HYDROLYZED SILK
Hydrolyzed Silk is a widely used ingredient in the hair care segment. It is a kind of a protein that provides the required amino acids to hair shafts in order to make them stronger and shinier. This ingredient is also used in skincare because it protects the surface against harmful environmental factors and is hydrating. Hydrolyzed Silk protein is commonly found in products like shampoos, conditioners and lotions. This ingredient is quite similar to the proteins that are naturally present in the skin and hair. Hence, Hydrolyzed Silk works wonders in replenishing any lost protein that causes dryness and damage.

What is HYDROLYZED SILK used for?

Hydrolyzed Silk protein is extremely similar to the proteins found in our own bodies. It is thus an excellent external source of protein that positively impacts skin and hair.
  • Hair care: It aids in smoothness and silkiness. Due to lack of nutrition or chemical treatments, the hair shafts lose their protein and become dry, dull and damaged. Hydrolyzed Silk makes up for this loss of nutrition
  • Skin care: It acts as a humectant that pulls water to the outer layers of the skin and locks it. This results in a soft, supple and plump surface. Hydrolyzed Silk also forms a barrier on the skin to protect it against the harmful stressors of the environment. It is a good conditioning agent that makes cosmetic products more effective and prevents them from drying out the the surface that it is applied on. It gives a smooth texture to the products and a radiant glow to the skin

Origin

Hydrolyzed Silk is a natural ingredient that is derived from the leftover cocoons made by silkworms. The purest form of silk protein is extracted from this byproduct and is then cleansed, degummed and combed. After a controlled hydrolysis procedure, Hydrolyzed Silk protein is obtained. In its raw form, this ingredient appears as an amber colored liquid and has a characteristic mild odor.

Safety profile

Hydrolyzed Silk is a safe ingredient and is essential for the good health of skin and hair. Hydrolyzed Silk is not vegan as it is derived from an animal by-product. However, it is considered cruelty free as it is derived from the cocoons that have already been departed by the silkworms. Additionally, limited data shows no risk of use of Hydrolyzed Silk during pregnancy.
