sr-(Spider Polypeptide-1 Oligopeptide-178) is a single-chain recombinant polypeptide that repeats a part of spider silk protein. It is a white, soft powder produced by fermentation with gene-modified yeast in a nutrient-rich medium.
Due to its specific sequences, sr-(Wasp Spider Polypeptide-1 Oligopeptide-178) acts as a protective film-forming agent that shields skin and hair from environmental damaging factors, including pollution, UV radiation, and the blue-light spectrum. In addition, it is an emollient that provides a better sensory profile than conventional silicone-based ingredients.
Incorporated in skin care applications, sr-(Wasp Spider Polypeptide-1 Oligopeptide-178) reveals a healthy skin appearance, silky soft texture, and instant firming effect. It is rapidly biodegradable, friendly to skin microflora, and provides long-lasting protection without buildup.
In hair care applications, sr-(Wasp Spider Polypeptide-1 Oligopeptide-178) helps hair styling, improves curl retention, and exposes a healthier appearance. It can also be used in decorative cosmetics to enhance emolliency, pigment dispersion, and payoff. It is a biotechnological, stable, and potent peptide that inherits beneficial properties from spider silk and is used as a sustainable ingredient in various personal care products.References
