Introduction-Hydrolyzed silk protein |
Water-soluble mixed amino acids, also called Fibroin-90, whose average molecular weight is about 90, which is acquired after the hydrolysis of silk fibroin. White or creamy white powder, or faint yellow transparent liquid, the ninhydrin reaction is positive.
Silk powder is a kind of silk protein with high molecular weight, water soluble. Silk Powder has the function of excellent natural humidity-control and caring for one’s skin, preventing part of ultraviolet radiation, prevent and curing some skin disease result from all kinds of dampness and dryness. It has super effect used in prevent sunshine produce.
The silk powder possesses the unique ability of absorbing oil, therefore it is suitable for the cosmetics applied to the oily skin. The particle size is from 5um to 100um with various specifications. Our extra fine Silk Powder can more easily mixed with cosmetic than common ones with thinner particle size.

Function of Hydrolyzed silk protein |
|
(1)Mixed amino acids, a kind of highly practical nutrient substance with higher nutritive value, is produced through biochemistry technology which adopts the raw material of mulberry silk in which alanine, serine and glycine account for more than 83%. (2)Glycine and Serine of silk essence are raw materials to synthesize protein in organisms, and are also precursors for synthesis of glutathione, which has a preventive effect on cardiovascular diseases, cancer and aging; Glycine also has an antidotal action on the detoxication of aromatic compounds which can cause cancer; alanine promotes the alcohol metabolism, protects the liver and prevents people from being drunk; tyrosine has a good effect on preventing senile dementia. (3)Silk essence can easily impenetrate into the dermis layer of skin, be quickly absorbed by the skin, and takes part in enzyme activities, which obtains the actions of humidity, moisturizing, UV radiation, inhibiting melanin production, preventing skin aging and nourishing the skin.
