Benefits:
Protects hair from moisture loss and conditions it to provide a silky, smooth finish Provides moisture balance and promotes suppleness, shine and elasticity This form of protein can penetrate very deeply into the hair cortex to strengthen and repair
Silk amino acid (SAAs) also known as Sericin is a natural water-soluble glycoprotein extracted from raw silk. It is used as an additive in skin and hair care products due to its high levels of serine which has excellent moisture preservation characteristics. As a water-based additive it is used to provide a protective barrier and silky feel to lotions, soaps, personal lubricants, hair and skincare products.
Silk amino acids are produced by hydrolyzing (or breaking apart) silk proteins into smaller peptide chains, typically 18 to 19 amino acids in length. Silk amino acids have a lower molecular weight than silk protein powders and are moisturizing to skin and hair.
Silk amino acids are used in formulating shampoos, conditioner, hair treatments, bodywash, body lotions, cleansers, toners and facial moisturizers, mascara, lipstick and color cosmetics.
Silk fibroin is a product extracted from pure natural silk. Silk consists of sericin and fibroin, containing 18 amino acids. Among them, the content of silk, C, glycine is the most, accounting for more than 80% of the total, used in cosmetics silk essence, is a mixture of free amino acids from the decomposition of silk fibroin protein, its average molecular weight of about 90, easy to be absorbed by the human body.
Silk amino acid is a water-soluble mixed amino acid obtained after the hydrolysis of silk fibroin protein, and its average molecular weight is about 90, also known as silk fibroin-90. White to beige powder or light yellow transparent liquid, positive for ninhydrin reaction.
Application features:
With silk from feed silkworm as raw materials, refined through biological process to get the mixed amino acid (silk essence), more than 85% of whose content are alanine, serine and glycin, is a functionally prominent nutrient with higher nutritional value.
Glycin and serine can not only be used as the essential materials of synthesizing protein in organism, but also be used as the predecessor of synthesizing the glutathione (GSH, SSG), which has certain preventive actions on heart disease and cancer. Meanwhile, the glycin also has the detoxication effects for some aromatics which can cause cancer. The rich alanine also helps promoting the metabolism of alcohol in human body and protecting liver. Moreover, tyrosine has obvious effect on preventing the old from Alzheimer disease.
Silk amino acid is very easy to permeate the derma layer of skin and get absorbed, nurturing skin as well. Due to its action in the enzyme metabolism, silk amino acid can keep and adjust moisture, prevent skin from ultraviolet radiation, restrain splash generation, facilitate anti-aging for skin.
The main function of silk amino acids in cosmetics and skin care products is moisturizing agent, whitening and freckle removal. The risk coefficient is 1, which is relatively safe and can be used with confidence. It generally has no effect on pregnant women, and silk amino acids have no acne-causing effect.
Among them, the content of alanine, serine and glycine accounts for more than 85%, which is a nutrient with outstanding function and high nutritional value. In the case of a good degree of hydrolysis, silk essence easily penetrates into the dermis of the skin, is quickly absorbed by the skin, and participates in the activities of enzymes in the body to achieve the role of moistening, moisturizing, preventing ultraviolet radiation, inhibiting melanin production, anti-skin aging and nourishing the skin.
Applications:
Shampoos, conditioners, hair treatments
Body wash, cleansers
Body creams, lotions, and gels
Facial toners and moisturizers
Mascara, lipstick and color cosmetics
Nutritive products for brow and lash
Are silk amino acids really proteins?
Silk amino acids are derived from fibroin in silk. These amino acids are extracted from silk fibers and are used in a variety of products, including supplements and skin care products. However, while silk amino acids are derived from proteins, it is important to understand that not all amino acids are proteins.
Proteins are made up of amino acids held together by peptide bonds. While silk amino acids do contain amino acids, they are not linked together in the protein structure. This means that silk amino acids are not technically considered as a protein source.
Although silk amino acids are not considered a protein source, many manufacturers still claim that they are. This is because silk amino acids contain many of the same amino acids as proteins, including glycine, alanine and serine.
While silk amino acids may benefit overall health, they should not be used as a source of protein. If you want to increase your protein intake, it's best to do so through whole food sources, such as meat, eggs, and beans.
In summary, although silk amino acids are derived from proteins, they are not the source of proteins themselves. It is important to understand the science behind silk amino acids to avoid being frustrated by potentially inaccurate marketing claims. As always, it is important to maintain a balanced diet and consult a healthcare professional before adding any supplements to your daily diet.
Dosage information
There is insufficient evidence to recommend an optimal dosage of silk amino acids for human supplementation, although it is known that for any purpose where silk amino acids need to be absorbed a hydrolyzed form of the supplement is required. Hydrolyzed silk amino acids are not required if the target are the intestines or colon.
