RESUMO

BACKGROUND: Lead (Pb) content in lipsticks and potential life-long exposure of which might cause severe effects in consumers are an important concern for public. Thus, studies emphasize that lead exposure has no safe levels. METHODS: From 10 different brands, in total, 25 solid, gloss and creamy lipsticks are deployed from Turkish markets that are also categorized in two different price ranges. In order to evaluate the blood Pb levels in children, the United States Environmental Protection Agency's 'Exposure Uptake Biokinetic Model' is utilized. To assess the health risk of chronic usage both for children and adults, oral daily systemic exposure levels are calculated with the worst-case scenario and are compared with Maximum Allowable Dose Level for lipsticks. For lifetime risk assessment, exposure is assumed to start by age 7, and four different exposure scenarios have been deployed. RESULTS: The mean lead content of lipsticks shows significant statistical differences between the high- and low-priced lipstick groups. Daily level and total risk for lifetime Pb exposure from deployed lipsticks are below the acceptable risk levels but long-worn usage of products with routine monitoring of metal content is crucial for sensitive and unintended exposure groups.

RESUMO

Proteins in food and personal care products can pose a risk for an immediate immunoglobulin E (IgE)-mediated allergic response. Bioinformatic tools can assist to predict and investigate the allergenic potential of proteins. Here we present AllerCatPro 2.0, a web server that can be used to predict protein allergenicity potential with better accuracy than other computational methods and new features that help assessors making informed decisions. AllerCatPro 2.0 predicts the similarity between input proteins using both their amino acid sequences and predicted 3D structures towards the most comprehensive datasets of reliable proteins associated with allergenicity. These datasets currently include 4979 protein allergens, 162 low allergenic proteins, and 165 autoimmune allergens with manual expert curation from the databases of WHO/International Union of Immunological Societies (IUIS), Comprehensive Protein Allergen Resource (COMPARE), Food Allergy Research and Resource Program (FARRP), UniProtKB and Allergome. Various examples of profilins, autoimmune allergens, low allergenic proteins, very large proteins, and nucleotide input sequences showcase the utility of AllerCatPro 2.0 for predicting protein allergenicity potential. The AllerCatPro 2.0 web server is freely accessible at https://allercatpro.bii.a-star.edu.sg.

RESUMO

Fragrance chemicals are ubiquitous in cosmetics; however, they have been linked to allergic contact dermatitis. Allergy prevention involves two main strategies. Firstly, consumers are protected by limiting the maximum concentration of fragrance in a given product to avoid inducing allergies. Secondly, consumers who are already sensitized are protected by having the presence of such fragrance communicated to them. In this study, a validated GC-MS method was employed to quantify 26 allergens in 108 products marketed in Saudi Arabia.Additionally, a quantitative risk assessment (QRA) was performed on the studied cosmetics to determine the risk of inducing allergies. The results indicated that most allergens were present at acceptable concentrations, while 19 products carried a risk of inducing allergies. Furthermore, Lilial and Lyral, two prohibited fragrances, were detected in 97 products. It should be emphasized that this is the first study conducted in Saudi Arabia to evaluate the safety of the well-known 26 fragrance allergens. Hence, this study can potentially serve as a regional standard for future research.

RESUMO

Topical corticosteroids are used extensively in dermatology. Class 1 high potency topical steroids (HPTS) can result in unwanted side effects such as skin hypopigmentation, atrophy, and acneiform eruptions. HPTS are only legally available by prescription to ensure appropriate use in the United States (US). The authors have noticed a recent increase in patients presenting with steroid acne after buying HPTS products in beauty supply stores. These products are marketed as fade creams to treat hyperpigmentation and uneven skin tone. We assessed skincare products containing HPTS (clobetasol or betamethasone) in 33 beauty supply stores in Miami, FL; Washington, DC; and Baltimore, MD. Out of 33 beauty supply stores, 14 (42.42%) contained HPTS skincare products, and they were all located in Miami. Out of 15 stores visited in Miami, 14 (93.33%) contained skincare products with clobetasol, and 5 (33.33%) contained skincare products with both clobetasol and betamethasone. Of the stores selling HPTS skincare products, the number of different brands available ranged from 1 to 7, with an average of 4.21 different brands per store. Our study reveals that HPTS are readily available in over-the-counter skincare products in many beauty supply stores. HPTS skincare products were only available in one of three cities suggesting there may be a regional supplier distributing these products. It may also indicate that there is less oversight of retail stores in Miami with HPTS products. More studies are needed to quantify the availability of these products in different locations throughout the US. Further Studies can help identify this problem and raise awareness among consumers of the dangers of HPTS skincare products in beauty supply stores.

RESUMO

BACKGROUND: Cleansing is an important hygiene activity, necessary to prevent bacterial, fungal, yeast, and viral infection. However, in the presence of skin disease, cleansing can take on a new challenge: removing the sebum, sweat, externally applied substances, environmental debris, and organisms from the face without damaging the skin barrier. Since cleansers cannot easily distinguish between sebum and the intercellular lipids required to maintain skin integrity, unique cleansing technologies are necessary to provide mild cleansing for the many manifestations of sensitive skin. OBJECTIVE: This 4-week clinical study aimed to evaluate the appropriateness of a cosmetic facial foaming gel cleanser with a polymeric surfactant technology in a diverse sensitive skin population. METHOD: 85 subjects with sensitive skin due to eczema/atopic dermatitis, rosacea, acne, or cosmetic intolerance syndrome were evaluated via investigator grading, self-assessment questionnaire, noninvasive measurements, and digital photography. RESULTS: The foaming gel cleanser was well tolerated showing no significant increases in investigator-graded irritation endpoints. Sensitive skin subjects saw considerable reduction (P<0.05) in stinging, itching, burning, tightness, and overall sensitivity at 2 and 4 weeks. Improvements in smoothness, softness, clarity, radiance, and overall skin appearance, were observed by both the investigator and patients (P<0.05) at 2 and 4 weeks. CONCLUSION: The polymeric surfactant technology-based foaming gel cleanser provided a rich, foaming lather that felt gentle and left skin feeling comfortable.

RESUMO

BACKGROUND: During the last 15-20 years, allergic contact dermatitis from acrylates-containing nail cosmetics (acrylic nails, gel nails, gel nail polish) has been increasingly reported. 2-Hydroxyethyl methacrylate (HEMA) is considered to be the major allergenic culprit; few data on its presence in nail cosmetics are available. OBJECTIVES: To investigate (1) the frequency in which HEMA and di-HEMA trimethylhexyl dicarbamate are present in nail cosmetics; (2) whether nail cosmetics comply with EU regulations; (3) which other (meth)acrylates are present in nail cosmetics and how often. METHODS: One-line market survey. RESULTS: HEMA was present in nearly 60% of 394 cosmetic nail products and di-HEMA trimethylhexyl dicarbamate in 34%. Mandatory warnings on the packages of products containing HEMA were absent in 35% ('For professional use only') resp. 55% ('Can cause an allergic reaction'). Forty-five other (meth)acrylates were identified, of which the most frequent were hydroxypropyl methacrylate (25%), isobornyl methacrylate (16%) and trimethylolpropane triacrylate (12%). Some ingredient lists mentioned non-INCI names or non-specific names. CONCLUSIONS: HEMA was by far the most common ingredient of nail cosmetics, being present in nearly 60% of the products. Violations of EU legislation occurred in >30% (mandatory warnings missing) resp. 10% (mislabelling) of nail cosmetics.

RESUMO

BACKGROUND: The growing popularity of nail techniques based on acrylates has led to a higher frequency of sensitization in both nail technicians and users. OBJECTIVES: The study aimed to assess cases of allergic contact dermatitis (ACD) caused by acrylates in individuals with occupational or non-occupational exposure to nail techniques. METHODS: A preliminary study was conducted on 30 patients with ACD caused by acrylates in nail techniques, who were patch tested from September 2022 to March 2023 at the First Department of Dermatology and Venereology of Andreas Syggros Hospital, Athens, Greece. RESULTS: Thirty female patients with ACD to acrylates were documented (15 users and 15 nail technicians and users). The most common allergens were: 2-hydroxyethyl methacrylate (HEMA), 2-hydroxypropyl methacrylate (HPMA) and ethyleneglycol dimethacrylate (EGDMA), which tested positive in all 30 patients (100.0%). Twenty patients (66.7%) had been exposed to dental procedures involving acrylates, before the onset of ACD. Nail technicians exhibited extensive skin lesions, 40.0% experienced ACD within the first year of work and 13.3% during their professional practice. Three of them (20.0%) had to discontinue their work. CONCLUSION: Acrylates have been identified as potent allergens, necessitating the implementation of safety measures for the use of these chemicals in nail techniques.

RESUMO

BACKGROUND: Over the last 10 years, allergic contact dermatitis (ACD) from acrylate-containing nail cosmetics (acrylic nails, gel nails, gel nail polish) has been reported repeatedly. OBJECTIVES: To investigate the frequency and clinical features of ACD in nail cosmetics in a university hospital in Amsterdam, The Netherlands. PATIENTS AND METHODS: A retrospective study in patients diagnosed with ACD from acrylate-containing nail cosmetics at the Amsterdam University Medical Centers between January 2015 and August 2023. RESULTS: Sixty-seven patients, all women, were diagnosed with ACD from nail cosmetics, representing 1.6% of all individuals and 2.3% of all women patch tested in this period. Sixty-five of sixty-seven (97%) subjects had a positive patch test to 2-hydroxyethyl methacrylate (HEMA). Forty-nine patients (73%) were consumers and 18 (27%) were professional nail stylists. The sites most frequently affected with dermatitis were the fingers (79%), hands (40%) and the head and/or neck. Avoidance of contact with acrylate-containing products resulted in complete clearing of dermatitis in 80% of patients. CONCLUSIONS: ACD from acrylate-containing nail cosmetics is frequent in women patch tested in Amsterdam. Nearly all were identified by a positive patch test to 2-hydroxyethyl methacrylate in the (meth)acrylate series or the European baseline series.

RESUMO

BACKGROUND: Monitoring of adverse events induced by cosmetics performed by health authorities, known as cosmetovigilance, has been relied on the collection of case notifications. OBJECTIVES: We aimed to show how a contact dermatitis registry can contribute to the cosmetovigilance of emerging allergens. We used the example of phenylethyl resorcinol, an infrequent allergen with only 6 previous cases reported in Europe and Japan since 2013. METHODS: A systematic search in the Spanish Registry of Contact Dermatitis and Cutaneous Allergy (REIDAC) database was performed to identify patients with positive patch test to phenylethyl resorcinol or cosmetics that contains it between June 2018 and January 2023. We collected the main clinical features of these patients and compared them with those of patients recorded in the registry with similar epidemiological features. RESULTS: Thirteen patients with positive patch test to phenylethyl resorcinol were identified. All the patients were women with a mean age of 42 years (range 32-59) and their lesions were mainly in the face. CONCLUSION: Assessing the importance of infrequent allergens based solely on a case series is difficult. Multicentre registries facilitate the collection of cases and provide appropriate background information for new allergens.

RESUMO

BACKGROUND: Reports of allergic contact dermatitis (ACD) to phytonadione epoxide (PE) in cosmetics suggest that PE is as powerful a sensitiser as its parent compound phytonadione. OBJECTIVE: To evaluate a case series of ACD to PE in Spain. METHODS: We reviewed the records of 20 patients with ACD to cosmetics containing PE diagnosed across Spain between January 2019 and June 2023. RESULTS: All 20 patients developed patch test (PT) or repeated open application test (ROAT) reactions to cosmetics containing PE. All involved women with eyelid eczema. PT or ROAT with PE preparations were positive in 17/20 (85%). PE at 1%, 5%, 10% and 20% in pet. was patch-tested in 8/17, 14/17, 11/17 and 8/17 patients; being positive in 6/8 (75%), 13/14 (92.85%), 11/11 (100%) and 8/8 (100%), respectively. CONCLUSION: Regulators should, not only ban the specific dangerous cosmetic ingredients, but also consider to ban or keep under close surveillance those closely related products or derivatives that might potentially cause similar harmful effects. PTs with PE are suggested to be performed at a 5% concentration in pet. Higher concentrations (10% pet.) should be tested whenever PTs with 5% pet. PE are negative.

RESUMO

INTRODUCTION: Medical devices (MDs) have a long history of use, and come with regulatory frameworks to ensure user safety. Although topically applied MDs in the form of gels and creams might be used on damaged skin, their composition is often similar to that of cosmetic products applicable to intact skin, especially in terms of preservatives and fragrances. However, unlike cosmetics, these products are not subject to compound-specific restrictions when used in MDs. OBJECTIVE: This study aimed to identify and quantify preservatives and fragrances in topically applied MDs and assess their safety towards the Cosmetic Regulation (EC) 1223/2009. METHOD: Sixty-nine MDs available on the EU market were subjected to previously validated liquid chromatography tandem mass spectrometry (LC-MS/MS) and gas chromatography-mass spectrometry (GC-MS) methods to identify and quantify occurring preservatives and fragrances. RESULTS: Findings revealed that 32% of the examined MDs did not provide comprehensive ingredient lists, leaving users uninformed about potential risks associated with product use. Furthermore, 30% of these MDs would not meet safety standards for cosmetic products and, most significantly, 13% of the analysed samples contained ingredients that are prohibited in leave-on cosmetics. CONCLUSION: Results highlight the pressing demand for more stringent requirements regarding the labelling and composition of MDs to enhance patient safety. Improved regulation and transparency can mitigate potential risks associated with the use of topically applied MDs.

RESUMO

BACKGROUND: Fragrance substances are a frequent cause of contact allergy worldwide. Fragrance exposure varies by sex, age and possibly country, influenced by cosmetic availability, environmental conditions and cultural practices. OBJECTIVES: To systematically review and gather prevalence of sensitization to fragrance mix I (FM I) and fragrance mix II (FM II) in consecutively patch tested European dermatitis patients. METHOD: A total of 4134 publications on patch test results of European dermatitis patients, published from 1981 to 2022, were systematically reviewed according to a previously registered and published PROSPERO protocol. RESULTS: Eighty-four eligible original articles were analysed. Overall prevalence of sensitization to fragrance mix I (FM I) was 6.81% (95% CI: 6.37-7.28), and FM II was 3.64% (95% CI: 3.3-4.01). Sensitization to FM I was most prevalent in Central and Eastern Europe and to FM II in Western Europe. No clear time trends were observed. Among paediatric dermatitis patients, sensitization prevalence for FM I and FM II was 4.09% (95% CI: 3.37-4.96) and 2.17% (95% CI: 1.53-3.07). CONCLUSION: The frequency of positive patch test results for both FMI and FMII remains high. Sensitization is also prevalent among children. Enhanced regulation and labelling of cosmetic products play a vital role in averting exposure and sensitization to fragrance allergens.

RESUMO

Frequent use of methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) and MI in cosmetic products has been the main cause of widespread sensitization and allergic contact dermatitis to these preservatives (biocides). Their use in non-cosmetic products is also an important source of sensitization. Less is known about sensitization rates and use of benzisothiazolinone (BIT), octylisothiazolinone (OIT), and dichlorooctylisothiazolinone (DCOIT), which have never been permitted in cosmetic products in Europe. BIT and OIT have occasionally been routinely patch-tested. These preservatives are often used together in chemical products and articles. In this study, we review the occurrence of contact allergy to MI, BIT, OIT, and DCOIT over time, based on concomitant patch testing in large studies, and case reports. We review EU legislations, and we discuss the role of industry, regulators, and dermatology in prevention of sensitization and protection of health. The frequency of contact allergy to MI, BIT, and OIT has increased. The frequency of contact allergy to DCOIT is not known because it has seldom been patch-tested. Label information on isothiazolinones in chemical products and articles, irrespective of concentration, is required for assessment of relevance, information to patients, and avoidance of exposure and allergic contact dermatitis.

RESUMO

BACKGROUND: Professional ice hockey players may contract irritant and allergic contact dermatitis. AIMS: To investigate the presence of contact allergy (CA) in professional ice hockey players in Sweden. METHODS: Ten teams from the two top leagues were assessed for potential occupational exposure to sensitizers. Exactly 107 players were patch tested with an extended baseline series and a working series, in total 74 test preparations. The CA rates were compared between the ice hockey players and controls from the general population and dermatitis patients. RESULTS: One out of 4 players had at least one contact allergy. The most common sensitizers were Amerchol L 101, nickel and oxidized limonene. CA was as common in the ice hockey players as in dermatitis patients and significantly more common than in the general population. Fragrances and combined sensitizers in cosmetic products (fragrances + preservatives + emulsifier) were significantly more common in ice hockey players compared with the general population. CONCLUSION: The possible relationship between CA to fragrances and cosmetic products on the one hand and the presence of dermatitis on the other should be explored further.

RESUMO

BACKGROUND: Mainly women work as foot care specialists (FCS). They are at risk to develop occupational dermatitis (OD). OBJECTIVES: The objective of this study is to describe the contact sensitisation pattern of female FCS with OD. METHODS: In a retrospective study, patch test and clinical data collected by the Network of Departments of Dermatology (IVDK) from 2008 to 2022 were analysed. Data of 116 female FCS with OD were compared with data of 13 930 female patients with OD working in other professions and 78 612 female patients without OD. RESULTS: Hand dermatitis (93.1%) was significantly more common and face dermatitis (0.9%) significantly less common in female FCS with OD compared to other female patients with or without OD. Frequent suspected allergen sources were disinfectants, gloves, leave-on and nail cosmetics. Occlusion and wetness were important co-factors. The most common diagnoses were irritant contact dermatitis (26.7%) and allergic contact dermatitis (21.6%). No sensitisation to any of the baseline series allergens was significantly more frequent in female FCS with OD than in the two control groups. However, sensitisations to allergens which FCS are abundantly exposed to, including fragrances, preservatives, rubber ingredients and disinfectants, were most common. CONCLUSIONS: FCS should be aware of the OD risk and prevention should be promoted.

RESUMO

BACKGROUND: Considering consumer trends toward the use of "clean" personal care products and increasing recognition of childhood allergic contact dermatitis, we sought to characterize the allergen profile of such children's products. METHODS: Ingredients of baby washes/shampoos, bubble baths, and moisturizers identified using the "Clean Baby" filter on Target®'s online marketplace were analyzed for relevant pediatric contact allergens. RESULTS: Product compositions declared fragrance in 82% of products, Compositae in 46%, cocamidopropyl betaine in 45%, glucosides in 37%, propylene glycol in 12%, lanolin in 1%, and no allergens in 9%-methylisothiazolinone and formaldehyde were not found. CONCLUSION: Children are greatly impacted by atopic dermatitis and skin barrier dysfunction, which underscores a need for greater public awareness of sensitizing and irritating ingredients, particularly regarding pediatric personal care products.

RESUMO

BACKGROUND/OBJECTIVES: In the last 10 years methylisothiazolinone (MI) emerged as a global cause of preservative-related ACD. New Zealand has liberal regulations for the MI concentration limit in cosmetic products compared to Europe and Australia. The aim of this study was to evaluate the prevalence of MI sensitisation in New Zealand, explore sources of MI exposure and make recommendations on New Zealand regulations for MI use. METHODS: This retrospective study included data from patients who underwent patch testing with MI from 2008 to 2021 in a tertiary hospital dermatology clinic and a private dermatology clinic in Auckland, New Zealand. Patient baseline characteristics were recorded along with results of patch testing. Sources of MI exposure were identified from medical records. RESULTS: Over the study period, 1049 patch tests were performed in 1044 patients. MI was only tested as a stand-alone allergen from 2015; positive reactions to MI increased from 5.3% in 2015 to a peak of 11.9% in 2017 and then decreased to 6.4% in 2021. The most common source of MI exposure was shampoo or conditioner (27.7% of all relevant reactions) followed by occupational exposures to paints, biocides or glue (19.1%). CONCLUSION: Both sensitisation and ACD to MI appear to be decreasing, likely secondary to changes in product compounding due to stricter concentration limits internationally. We recommend New Zealand adopt lower MI concentration limits for cosmetics to match the limits of Australia and Europe.

RESUMO

Rinse-off cosmetic products, primarily shampoos, are frequently implicated in the onset of allergic contact dermatitis (ACD) caused by alkyl glucosides (AGs). AGs are increasingly popular surfactants and known contact allergens. Glucoside-induced ACD was most frequently observed with shampoos and skin-cleansing products in both consumer and occupational settings. Thereby, studies have shown that atopic individuals are the most susceptible to ACD. Also, several investigations have indicated that individuals with sensitive skin might be more prone to skin allergies. This is why the presence of AGs was investigated in shampoos and body cleansers marketed as hypoallergenic or for sensitive skin. For this purpose, the website of Amazon.com was surveyed. Four groups of cosmetics were obtained by using the following keywords: "hypoallergenic shampoo for adults," "sensitive skin shampoo for adults," "hypoallergenic body cleanser for adults," and "sensitive skin body cleanser for adults." The first 30 best-selling cosmetics in each group were investigated for the presence of AGs, by analyzing the product information pages. The results showed that as much as 56.7% of hypoallergenic shampoos contained AGs, as ingredients, whereas the percentage was somewhat lower for other product categories. Even though decyl and lauryl glucoside were nearly ubiquitously used AGs in cosmetics over the past decade, the most commonly present AG in our analysis was coco-glucoside. The results of this study indicated a necessity to include coco-glucoside in the baseline series of patch testing allergens. Industry, regulators, and healthcare providers should be made aware of the frequent presence of AGs in rinse-off cosmetic products marketed as hypoallergenic or for sensitive skin to ensure the safety and well-being of consumers and patients.

RESUMO

Aim: Lip care cosmetics products are any external preparation used by people to prevent drying, chapping, dullness, and beautification of lips. This study aimed to review the literature on allergic reactions induced by different types of lip care cosmetic products. Methods: A literature search was performed in PubMed from inception to June 2022. The study included articles published in English and available in full text. References of illegible articles were searched. Studies describing any patient who developed allergic contact dermatitis after the application of lip care cosmetic products were included. Results: A total of 47 reports consisting of 58 individuals experienced allergic reactions to lip care products. Several lip care cosmetics products, such as lipsticks, lip balms, lip salve, lip gloss, lip liner, and lip plumper, were found to be associated with allergic reactions. The most common ingredients that caused the allergic contact dermatitis were castor oil, benzophenone-3, gallate, wax, and colophony. Conclusions: Lip care cosmetics products contain several components that have been associated with allergic reactions. Awareness needs to be created among the general public and dermatologists regarding the presence of possible allergens in lip care cosmetic products.

RESUMO

OBJECTIVE: To study the ocular effects seen among eye cosmetic wearers in the Indian Population. METHODS: This cross-sectional study was conducted on female participants who had fulfilled the inclusion and exclusion criteria. A detailed history was obtained and thorough ophthalmic evaluation was done. Mann Whitney U test was used. Statistical analysis was done using IBM SPSS. p < .05 was taken as the level of statistical significance. RESULTS: Among a total of 225 participants in our study, the mean age was 24.23 ± 1.8, which comprised of young student females. Majority of the females used one eye cosmetic with Kajal (n = 156) being the most predominant. Most frequently encountered symptom upon using eye cosmetics was watering from eyes and ocular pain was the least encountered symptom. Anterior segment examination showed- allergic conjunctivitis and meibomian gland dysfunction being the most and least predominant, respectively. Our study highlights that Kajal predisposes the eyes to significant ocular morbidity with p = .039 for dry eye disease, p = .041 for allergic conjunctivitis, p = .036 for conjunctival pigmentation. Prolonged use of such formulations for more than 4 times a week (p = .046) or even daily (p = .031) for a duration of either 1-5 years (p = .033) or greater than 5 years (p = .027) was found to be statistically significant in causing ocular signs. Non removal of eye cosmetics at the end of the day was significant in causing allergic conjunctivitis (p = .035) and conjunctival pigmentation (p = .021). Plain tap water has been found to be the least effective technique in the removal of such ocular cosmetics with a statistical significance of p = .031 in causing ocular signs. CONCLUSIONS: Eye cosmetics are a significant contributor to the development of ocular surface diseases. Removal of products along with decreased usage seems to be a significant contributor in dampening unwanted adverse effects.
