ABSTRACT
Purpose:
This study aimed to extract the oil from Gryllus bimaculatus de Geer, evaluate its potential for cosmeceutical applications, and develop nanoemulsions to promote the cosmeceutical capabilities of the oil.Methods:
G. bimaculatus oil was produced by the cold pressing method. Its fatty acid compositions were assessed by fatty acid methyl ester/gas chromatographic-mass spectrometry. The antioxidant activities of the oil were investigated in terms of radical scavengers, reducing power, and lipid peroxidation inhibition. The whitening effects were investigated through anti-tyrosinase activities, whilst the anti-aging effects were investigated through inhibition against collagenase, elastase, and hyaluronidase. The irritant effects were investigated by the hen's egg chorio-allantoic membrane test and the cytotoxicity assay in immortalized human epidermal keratinocytes and human foreskin fibroblast cells. The nanoemulsions were developed, characterized, and evaluated for their stability and cosmeceutical properties.Results:
G. bimaculatus oil, rich in linoleic acid (31.08 ± 0.00%), oleic acid (30.44 ± 0.01%), palmitic acid (24.80 ± 0.01%), and stearic acid (7.61 ± 0.00%), demonstrated promising cosmeceutical properties in terms of antioxidant, anti-tyrosinase, and anti-skin ageing activities. Besides, the oil was safe since it induced no irritation or cytotoxicity. G. bimaculatus oil was successfully developed into nanoemulsions, and F1, composed of 1% w/w G. bimaculatus oil, 1.12% w/w polysorbate 80, 0.88% w/w sorbitan oleate, and 97% w/w DI water, had the smallest internal droplet size (53.8 ± 0.6 nm), the narrowest polydispersity index (0.129 ± 0.010), and a pronounced zeta potential (-28.23 ± 2.32 mV). All cosmeceutical activities of the oil were significantly enhanced after incorporation in the nanoemulsions (p < 0.001), particularly the whitening effects.Conclusion:
G. bimaculatus oil nanoemulsion was an attractive cosmeceutical formulation with potent whitening effects, along with antioxidant and anti-aging properties. Therefore, nanoemulsion technology was found to be an effective strategy for improving the cosmeceutical properties of G. bimaculatus oil.Key words
