ABSTRACT

The Modernization of Cosmetics Regulation Act of 2022 (MoCRA) amends the Food, Drug and Cosmetic Act (FDCA), elevating the standard of proof of safety (better known as a "safety standard") for cosmetics to the standard of a "reasonable certainty … [of] … safe."a standard equal to that of food ingredients. The standards of the proof of safety differ for various classes of FDA-regulated product categories e.g., cosmetics, dietary supplements, food ingredients and food itself. This manuscript describes the various standards of proof, the essential differences between the standards, key elements required to achieve a particular standard and, compares the standards to more familiar legal terms such as "a preponderance of the evidence" or "beyond reasonable doubt." The standards of proof for these product categories are also ranked according to increasing threshold for achievement of "safe" status. Lastly, this manuscript suggests how the requirements for the high standard of a "reasonable certainty of safe" (or "reasonable certainty of no harm") might be met.

ABSTRACT

OBJECTIVES: To determine the compliance of online vendors to the UK Opticians Act 1989 Section 27 requirements and safety regulations for cosmetic contact lens (CCL) sales and the quality of online CCL health information. METHODS: The top 50 websites selling CCLs on each three search engines, namely Google, Yahoo, and Bing, were selected. Duplicates were removed, and the remaining websites were systematically analyzed in February 2023. UK legal authorization for CCL sales was assessed using the Opticians Act Section 27 and safety regulations determined by the presence of Conformité Européene (CE) marking. The quality and reliability of online information was graded using the DISCERN (16-80) and JAMA (0-4) scores by two independent reviewers. RESULTS: Forty-seven eligible websites were analyzed. Only six (12.7%) met the UK legal authorization for CCL sales. Forty-nine different brands of CCLs were sold on these websites, of which 13 (26.5%) had no CE marking. The mean DISCERN and JAMA benchmark scores were 26 ± 12.2 and 1.3 ± 0.6, respectively (intraclass correlation scores: 0.99 for both). CONCLUSIONS: A significant number of websites provide consumers with easy, unsafe, and unregulated access to CCLs. Most online stores do not meet the requirements set out in the Opticians Act for CCL sales in the United Kingdom. A significant number of CCLs lack CE marking, while the average quality of information on websites selling CCLs is poor. Together, these pose a risk to consumers purchasing CCLs from unregulated websites, and therefore, further stringent regulations on the online sales of these products are needed.

ABSTRACT

Botanical dietary supplement use is widespread and growing, therefore, ensuring the safety of botanical products is a public health priority. This commentary describes the mission and objectives of the Botanical Safety Consortium (BSC) - a public-private partnership aimed at enhancing the toolkit for conducting the safety evaluation of botanicals. This partnership is the result of a Memorandum of Understanding between the US FDA, the National Institute of Environmental Health Sciences, and the Health and Environmental Sciences Institute. The BSC serves as a global forum for scientists from government, academia, consumer health groups, industry, and non-profit organizations to work collaboratively on adapting and integrating new approach methodologies (NAMs) into routine botanical safety assessments. The objectives of the BSC are to: 1) engage with a group of global stakeholders to leverage scientific safety approaches; 2) establish appropriate levels of chemical characterization for botanicals as complex mixtures; 3) identify pragmatic, fit-for-purpose NAMs to evaluate botanical safety; 4) evaluate the application of these tools via comparison to the currently available safety information on selected botanicals; 5) and integrate these tools into a framework that can facilitate the evaluation of botanicals. Initially, the BSC is focused on oral exposure from dietary supplements, but this scope could be expanded in future phases of work. This commentary provides an overview of the structure, goals, and strategies of this initiative and insights regarding our first objectives, namely the selection and prioritization of botanicals based on putative toxicological properties.

ABSTRACT

In cosmetic products, the ingredient propylparaben (CAS No 94-13-3, EC No 202-307-7) with the chemical names Propyl 4-hydroxybenzoate and 4-Hydroxybenzoic acid propyl ester is currently regulated as a preservative in a concentration up to 0.14% (as acid) (Annex V/12a). In addition, a safe concentration was established for mixtures of parabens, where the sum of the individual concentrations should not exceed 0.8% (as acid). However, in such mixtures the sum of the individual concentrations of butyl- and propylparaben and their salts should not exceed 0.14%. Propylparaben was subject to different safety evaluations in 2005 (SCCP/0874/05), 2006 (SCCP/1017/06), 2008 (SCCP/1183/08), 2010 (SCCS/1348/10), 2011 (SCCS/1446/11), and in 2013 (SCCS/1514/13). On the basis of the safety assessment of propylparaben, and considering the concerns related to potential endocrine disrupting properties, the SCCS has concluded that propylparaben is safe when used as a preservative in cosmetic products up to a maximum concentration of 0.14%. The available data on propylparaben provide some indications for potential endocrine effects. However, the current level of evidence is not sufficient to regard it as an endocrine disrupting substance, or to derive a toxicological point of departure based on endocrine disrupting properties for use in human health risk assessment. The SCCS mandate does not address environmental aspects. Therefore, this assessment did not cover the safety of propylparaben for the environment.

ABSTRACT

Next generation risk assessment (NGRA) is an exposure-led, hypothesis-driven approach that has the potential to support animal-free safety decision-making. However, significant effort is needed to develop and test the in vitro and in silico (computational) approaches that underpin NGRA to enable confident application in a regulatory context. A workshop was held in Montreal in 2019 to discuss where effort needs to be focussed and to agree on the steps needed to ensure safety decisions made on cosmetic ingredients are robust and protective. Workshop participants explored whether NGRA for cosmetic ingredients can be protective of human health, and reviewed examples of NGRA for cosmetic ingredients. From the limited examples available, it is clear that NGRA is still in its infancy, and further case studies are needed to determine whether safety decisions are sufficiently protective and not overly conservative. Seven areas were identified to help progress application of NGRA, including further investments in case studies that elaborate on scenarios frequently encountered by industry and regulators, including those where a 'high risk' conclusion would be expected. These will provide confidence that the tools and approaches can reliably discern differing levels of risk. Furthermore, frameworks to guide performance and reporting should be developed.

ABSTRACT

Analysis of spontaneous reports of adverse events is an important source of information that can be used to improve consumer products. Various agencies have adverse event reporting requirements and many companies collect such data directly from consumers. Nonetheless, a universal framework is absent that identifies and evaluates spontaneously reported adverse events, and, most important, assesses the potential association between exposure and adverse events. We are presenting a three-part framework: Phase I - Intake and Documentation of Original Incidents; Phase II - In Depth Review and Follow-up of Phase I Incidents (enhanced, tailored questionnaire); Phase III - Association Assessment. The basis for scoring the strength of association between exposure and adverse events requires assessment of standard factors of association including: temporality; biological, physiological, or pharmacological plausibility; results of de-challenge; results of re-challenge; and consideration of confounding factors. Scores tied to the answers to these questions are totaled for each incident to determine the strength of association between exposure and reported adverse event. We propose that consumer product companies come together to adopt such an association assessment framework to improve adverse event management, obtain maximum value from the data obtained, and use the knowledge derived to improve overall product safety for consumers.

ABSTRACT

The "SCCS Notes of Guidance for the Testing of Cosmetic Ingredients and Their Safety Evaluation, 11 th Revision" (SCCS/1628/21) contains relevant and updated information on the different aspects of testing and safety evaluation of cosmetic substances in Europe. The emphasis is on cosmetic ingredients for which a concern has been expressed for human health. Indirectly, the Guidance also provides some advice on the safety of finished products. A general aim is to improve harmonised compliance with the current cosmetic EU legislation, Regulation (EC) No 1223/2009, for which animal testing and marketing bans fully apply from 2013 onwards. This means that no in vivo testing of ingredients or finished products is allowed in Europe for the purpose of cosmetics. For this reason, the SCCS has closely followed the progress made in regard to the development and validation of alternative replacement methods, also referred to as new approach methodology (NAM). The "SCCS Notes of Guidance" are regularly revised and updated in order to incorporate progress made and experience gained over time, in particular on the use of NAMs, and the new methods and data that became available since previous revision (SCCS/1602/18) formed the basis of the current (11 th) Revision.

ABSTRACT

The Cosmetic Regulation (EC) No 1223/2009 specifically covers the risk of nanomaterials used in cosmetic products. If there are concerns regarding the safety of a nanomaterial, the European Commission refers it to the SCCS for a scientific opinion. The Commission mandated the SCCS to identify the scientific basis for safety concerns that could be used as a basis for identifying and prioritising nanomaterials for safety assessment, and to revisit previous inconclusive SCCS opinions on nanomaterials to identify any concerns for potential risks to the consumer health. The SCCS Scientific Advice identified the key general aspects of nanomaterials that should raise a safety concern for a safety assessor/manager, so that the nanomaterial(s) in question could be subjected to safety assessment to establish safety to the consumer. The Advice also developed a list of the nanomaterials notified to the Commission for use in cosmetics in an order of priority for safety assessment, and revisited three previous inconclusive opinions on nanomaterials to highlight concerns over consumer safety that merited further safety assessment.

ABSTRACT

In 2019, the Dutch Food and Consumer Product Safety Authority performed a market surveillance for toy-slime (23 samples) and putty (16 samples). For 35% of the toy-slimes and 13% of the putties, the migration of boron exceeded the European legal limit of 300 and 1200 mg/kg respectively. In 36% of the toy samples, methylisothiazolinone (MI) and chloromethylisothiazolinone (CMI) were detected in levels up to 25 and 38 mg/kg, respectively, much higher than the European legal limit for aqueous toys intended for children younger than three. 59% of the toys contained other preservatives such as 2-phenoxyethanol, p-hydroxybenzoic acid and parabens. In 2 toy-slimes and 2 putties N-nitrosodiethanolamine (NDELA) was found in amounts up to 2.3 mg/kg. A risk assessment was performed for boron and NDELA. The estimated exposure to boron did not exceed the health based guidance value. The estimated exposure to NDELA from 2 toy-slimes may pose a health risk. For 2 putties the estimated exposure to NDELA was somewhat lower, but health risks could not be excluded. The presence of isothiazolinones may lead to skin sensitisation. It is recommended to extend the legal limit for NDELA, MI and CMI in finger-paint and labelling requirements to other aqueous toys.

ABSTRACT

Customized cosmetics immediately made on the spot are now in the market. The present study surveyed 1084 consumers to obtain general insights into their perceptions and perspectives on this novel type of cosmetic. Over half of the total respondents (57.2%) answered they were likely to purchase customized cosmetics; however, a large proportion of consumers also thought microbiological (59.2%)/chemical safety (69.4%) of cosmetics were not good. This reflects consumer anxiety regarding safety issues concerning the customized cosmetics. Even customized cosmetics are regulated by the cosmetic act in each country (i.e., the Cosmetic Act in the Republic of Korea, the Federal Food, Drug, and Cosmetic Act in the USA, and EC Cosmetic Regulation 1123/2009 in Europe), there have been no specific regulations for customized cosmetics made on the spot worldwide so far. To dispel consumer concerns and establish a principled market for the new cosmetics in the field, proper management plans should be established based on consumer surveys. This study indicated that consumers thought it was important to manage the facility/equipment and safety of raw materials (19.7%, each). We believe this study provides a valuable resource for understanding consumers' perceptions and requirements on customized cosmetics, which contributes to establishing future regulations and guidelines.

ABSTRACT

Dermal contact is the main route of exposure for most cosmetics; however, inhalation exposure could be significant for some formulations (e.g., aerosols, powders). Current cosmetic regulations do not require specific tests addressing respiratory irritation and sensitisation, and despite the prohibition of animal testing for cosmetics, no alternative methods have been validated to assess these endpoints to date. Inhalation hazard is mainly determined based on existing human and animal evidence, read-across, and extrapolation of data from different target organs or tissues, such as the skin. However, because of mechanistic differences, effects on the skin cannot predict effects on the respiratory tract, which indicates a substantial need for the development of new approach methodologies addressing respiratory endpoints for inhalable chemicals in general. Cosmetics might present a particularly significant need for risk assessments of inhalation exposure to provide a more accurate toxicological evaluation and ensure consumer safety. This review describes the differences in the mechanisms of irritation and sensitisation between the skin and the respiratory tract, the progress that has already been made, and what still needs to be done to fill the gap in the inhalation risk assessment of cosmetic ingredients.

ABSTRACT

The labeling of all ingredients contained in consumer products has been requested by consumers concerned regarding their safety. Consequently, regulatory agencies have set guidelines for industries on how to provide safety information regarding the ingredients in their products. However, discordant opinions were raised from stakeholders, resulting in the formation of a risk communication forum among industries, regulatory agencies, consumer groups, and academia. There are several methods that might be utilized to provide ingredient information to consumers: (1) listing all ingredients on the label of products, (2) providing major ingredients on the label of products, (3) presenting all ingredients on the websites of each manufacturer, and (4) listing major ingredients on the label of products and the remainder of ingredients (not on the label) on the websites. Each method might have its own advantages and disadvantages with respect to providing the information regarding the names of the ingredients used in consumer products to the consumers. A continuous risk communication forum might be an effective tool to facilitate an improved understanding of chemical information, toxicological science, regulatory guidelines, labeling methods, and consumers' concern. This study suggests that risk communication efforts may be helpful and a good opportunity for stakeholders to exchange opinions and reach a harmonious conclusion on labeling of consumer products ingredients.

ABSTRACT

Despite widespread and prolonged use of adult novelties, their health safety is not regularly tested or legally regulated. In the EU, adult novelties are subjected to the General Product Safety Directive, placing the burden of proof regarding safe products onto the manufacturers. The aim of our pilot study was to expand knowledge on potential application of in vitro methods for hazard prediction of extracts from final products. We subjected extracts of 20 adult novelties, purchased on the Czech market to toxicological tests including NRU cytotoxicity assay, sensitization tests DPRA and LuSens and the YES/YAS endocrine assay. Four samples produced cytotoxicity. Sensitization potential was recorded by DPRA (three samples) while the LuSens reported ten samples. Regarding endocrine disruption, three samples produced antiestrogen and antiandrogen effects. Six samples exhibited androgenic potential and one sample showed estrogenic potential. Positive results with possible health effects were recorded repeatedly for samples made of ABS, PVC and latex. The study has confirmed promising usefulness of our test methods combination with regard to safety testing of this type of consumer products. The results should be evaluated with care, however, the data bring added-value to the limited knowledge of mixture toxicology and are indicative for further testing.

ABSTRACT

Safety issues regarding consumer products contaminated with trace amounts of chemicals are of great concern to consumers, with the degree of concern occasionally escalating to the psychological syndrome, chemophobia (i.e., the fear of chemicals). Hazardous substances frequently implicated in safety concerns include heavy metals (arsenic, mercury, cadmium, and lead), volatile organic compounds (VOC) such as benzene and o-toluidine, pesticides, carcinogens, radioactive substances, and endocrine disrupting chemicals (EDC) such as bisphenol A and phthalates. To improve communication of risk to society, members of academia, government, consumer organizations, and industry participated in this workshop to discuss and exchange perspectives on trace chemical safety. From the perspective of academia, integrated risk assessments need to be implemented to encompass various exposure sources and routes. The identification and investigation of new exposure-related biomarkers are also recommended to verify direct causal relationships between specific chemical exposure and effects on human health. As for regulation, governments need to establish and maintain acceptable limits for trace chemicals in products. In addition, harmonized efforts need to be undertaken among government agencies to share regulatory limits and effectively control trace chemicals in consumer products. Manufacturers need to faithfully abide by Good Manufacturing Practice (GMP) guidelines, monitor sources of contamination, and minimize these for consumer safety. To effectively resolve safety issues arising from trace chemicals exposure, collaborative efforts are needed involving academia, government, consumer organizations, and industry. Further, scientific evidence-based risk assessment is a critical approach to effectively manage trace chemical safety issues.

ABSTRACT

The control of Salmonella in low water activity foods poses a challenge for the food industry because of its thermal resistance. The use of surrogate bacteria in a food plant is considered a critical component to validate processing steps. The objective of this study was to evaluate the use of Pediococcus acidilactici ATCC 8042, a generally recognized as safe bacterium (GRAS), as potential surrogate for Salmonella in commercial toasted oats cereal (TOC) and peanut butter. P. acidilactici was compared to a five-serovar cocktail of Salmonella and Enterococcus faecium NRRL-B2354, separately. Cultures were inoculated into TOC and thermal kinetic parameters (δ, ß) were determined at 80, 85, 90, and 95 °C using the Weibull model. In peanut butter, δ and ß parameters were obtained at 63, 68, 73, and 77 °C. In TOC, the δ values (initial decimal reduction time) of P. acidilactici were 63 and 7 min at 80 and 95 °C, respectively, and at all four temperatures they were not significantly different from δ values of E. faecium. The δ value of Salmonella at 80 °C (139 min) was two-fold greater than the other two bacteria's values (p < 0.05). In peanut butter, δ values of P. acidilactici ranged from 31 min at 63 °C to 2.6 min at 77 °C, and at all temperatures they were not significantly different from E. faecium's δ values. In peanut butter, all Salmonella cocktail's δ values were significantly smaller than P. acidilactici's with values of 2 min at 63 °C and 0.4 min at 77 °C. These results indicated that P. acidilactici was as heat tolerant as E. faecium in these food matrices. However, the thermal inactivation kinetic parameters suggested that P. acidilactici can only be considered a Salmonella surrogate in TOC at temperatures above 85 °C. Because of its greater thermal tolerance in peanut butter, P. acidilactici may be used as Salmonella surrogate if an additional safety factor is recommended.

ABSTRACT

Nanotoxicology and nanosafety has been a topic of intensive research for about more than 20 years. Nearly 10 000 research papers have been published on the topic, yet there exists a gap in terms of understanding and ways to harmonize nanorisk assessment. In this review, we revisit critically ignored parameters of nanoscale materials (e.g. band gap factor, phase instability and silver leaching problem, defect and instability plasmonic versus inorganic particles) versus their biological counterparts (cell batch-to-batch heterogeneity, biological barrier model design, cellular functional characteristics) which yield variability and nonuniformity in results. We also emphasize system biology approaches to integrate the high throughput screening methods coupled with in vivo and in silico modeling to ensure quality in nanosafety research. We emphasize and highlight the recommendation regarding bridging the mechanistic gaps in fundamental research and predictive biological response in nanotoxicology. The research community has to develop visions to predict the unforeseen problems that do not exist yet in context with nanotoxicity and public health hazards due to the burgeoning use of nanomaterial in consumer's product.

ABSTRACT

PURPOSE OF REVIEW: The purpose of this article is to review clinical manifestations and management of common pediatric foreign body ingestions, with a particular focus on some of the current trends. RECENT FINDINGS: Foreign body ingestion (FBI) is a problem that is frequently encountered by pediatric providers. As new toys and products enter the marketplace, there may also be new dangers from those objects not initially recognized. Some of the recent trends and findings in pediatric FBI include an increase in adolescent injury from ingestion of laundry detergent pods because of a popular game where participants are encouraged to bite or swallow the pods, and injuries associated with ingesting parts of a popular toy known as a 'Fidget Spinner'. SUMMARY: Adverse events resulting from FBI range the entire gamut from nonexistent or minor symptoms to moderate injury and rarely may be fatal. Factors such as age, type of object ingested, anatomic location of the foreign body, and timing from ingestion to receipt of medical attention all determine the risk posed to the child and guide management decisions. Because of the constant development of products, and the potential for the emergence of new and dangerous trends among children, continued surveillance by the medical community is important in monitoring and managing injuries associated with FBI.
