Hydrolyzed Silk Peptides
What is Hydrolyzed Silk Peptides?
Hydrolyzed silk peptides come from the fibroin protein in silkworm cocoons, specifically from Bombyx mori silk. Through hydrolysis, large silk proteins break into smaller, water-soluble peptides. In cosmetics, they serve as conditioning agents in skincare creams, serums, shampoos, and hair treatments. These peptides work by creating a thin, breathable film on the skin or hair surface, which helps retain moisture and provides a smooth feel. They act as humectants, attracting water to the surface, and contribute to antistatic properties in hair products. Their amino acid composition mimics some natural skin proteins, supporting a soft texture without clogging pores.
