Silk Peptides are a highly purified grade of natural silk power, processed in such a way as to retain the original physical structure and chemical composition of silk. This is a 100% natural silk protein, in a fine powder form for ease of use. It also has the unusual quality of holding and releasing moisture depending on the temperature and humidity of the surroundings. This product is easy to use, as it bonds well with essential oils, fragrant oils, colors and base materials used in skin and hair care. It is also stable over a wide range of pH levels again confirming the suitability of Silk Peptide for personal treatment products. Recommended usage rate is between 2-5% by weight.

Silk Additives - Which one is the right one?
Silk Powder, Silk Peptide, Silk Amino Acids; which one is best for your formulation? All of them contain 18 different amino acids, all come from the cocoon of the silk worm, and all have a chemical composition that is very close to that of human skin and hair making them a wonderful source of nourishment and maintenance.
The real difference is the size of the particles, which impacts water solubility and how deeply each one can penetrate the hair and skin. The more deeply it penetrates, the greater the therapeutic qualities but you'll lose some of the much coveted look and feel it provides on the surface.
Silk Peptide is the next size down from the powder and has better water solubility. Being a more refined product, its particle size allows it to penetrate the skin and hair thereby giving it a more therapeutic aspect to go along with appearance enhancements. The shine, elasticity, and smooth feel it provides to hair become apparent after it dries and turns into a protective crystalline film that is less sticky than collagen or keratin. Upon penetrating the skin, Silk Peptide helps to retain moisture and control the growth of melanin as well as still providing an attractive sheen.
Application: Silk Peptide can be used in a wide variety of products such as shampoo, conditioner, hair treatment, body wash, body lotion, cleaner, toner, makeup foundation, lipstick, mascara, color cosmetics.
