Silk protein hydrolysate (Hydrolyzed Silk) is a high-quality cosmetic active ingredient, an aqueous solution of silk proteins broken down into peptides and amino acids. Due to its low molecular weight, this hydrolyzed protein has exceptional penetrating properties. It is widely used in the production of professional cosmetics to restore hair structure and improve skin elasticity.
Personal hygiene and therapeutic cosmetics manufacturers find it beneficial to purchase hydrolysate in bulk to ensure stable production and guarantee visible results for the end consumer. The price of hydrolyzed protein is determined by the dry matter concentration and purity of the substance.
Silk protein hydrolysate. What is it and how is it used?
Many manufacturers are interested in the question: what is silk protein hydrolysate and how does it work in a formula? The hydrolysis process makes the protein water-soluble and bioavailable. Protein hydrolysate acts as a powerful moisturizing agent, creating a light, breathable film on the surface of the skin or hair.
Silk protein hydrolysate is used in the following areas:
- For hair:hydrolyzed silk for hair restores damaged areas of the cuticle, prevents split ends and makes combing easier. In conditioners and masks,silk protein hydrolysate for hair gives strands a characteristic "silky" texture. shine and softness.
- For the face: silk proteins for the face deeply moisturize the dermis, stimulate regeneration and provide a slight lifting effect.
- In cosmetology: silk proteins in cosmetology are valued for their ability to retain moisture and protect the skin from dehydration.
To create a sought-after product, technologists prefer to buy silk proteins in the form of a standardized hydrolysate, which is easily mixed with other active ingredients in the aqueous phase.
