Amino Acids
Silk
Amino Acids is also called the "Silk Essence", which the main
composition are the free amino acids and less amount of di-peptide
and tri-peptide with the average molecular weight of 90.
Application property
(1)The composition of silk essence is very easy to be
permeated to the derma layer of skin and to be absorbed by skin, so
as to meet the effectiveness of skin-nurturing.
(2)The silk essence have the better nourishing function
for the hair injured either by mechanism or chemicals, which can
permeate to the interior of injured hair (flaky structure) to repair
or protect it.
(3)The silk essence have a good dissolvability with
anionic, cationic, nonionic or amphoteric surfactants or multi-kinds
of oily materials, as well as a good compatibility in the formula of
cream or shampoo etc.
(4)Among the multi-kinds amino acid contained in
silk essence, the content of glycine is the highest. Not only can it
be used as the essential materials of synthesizing protein in the
internal of organism, but also as the precuror of synthesizing the
glutathione (GSH, GSSG), purine and heme, which the GSM plays a
certain preventive function for angiocardiopathy, carcinosis &
human senility. Meanwhile, the glycine also has the function of
detoxication for some aromatics which can cause cancer to human
body. The rich alanine in the silk essence has the functions of
promoting the metabolism of alcohol in human body to protect the
liver, and of reducing the blood sugar, therefore, it also is
accepted for the products of dispelling the effects of alcohol. This
property of silk essence have the wide application field in the
development of healthy foodstuff.

Package:
This product is packed in the aluminum-plastic compound bag in
vacuum condition 500gr, which the shelf life is
two years under the sealing condition.
Our
company is the pioneer of developing the silk essence successfully
in China and has got the import permission from the Japanese Medical
and Health Ministry to export the silk amino acids to Japan, which is widely applied in biscuit, candy, bean products, noodles,
ice cream, beverage and other nourishing foodstuffs.
