Silk Amino Acid 500 g

Bulk Silk Protein for Hair and Skin Care Formulations

Silk amino acid powder is a concentrated protein derivative obtained from natural silk fiber, widely used in hair and skin care manufacturing as well as in textile finishing and certain pharmaceutical applications thanks to its film-forming and moisture-binding properties. The 500 gram package is suited for studio and small-scale industrial production, giving formulators and brands a steady supply for regular batches of shampoos, masks, and serums without frequent reordering. This product belongs to the Amino Acids category, which brings together ingredients for building targeted formulas for skin and hair care.

The primary application is in leave-in and rinse-off hair care products, facial serums, lotions, and creams. Silk protein forms a thin film over the hair shaft that smooths the cuticle, reduces frizz, and adds shine, while on skin it helps bind moisture and leaves a noticeably softer feel. Beyond cosmetics, silk amino acid is used in textile impregnation processes, some pharmaceutical research formulations, and select nutritional products where a bioavailable amino acid source is desired.

When formulating, the powder is introduced into the water phase at temperatures no higher than 40-45 degrees Celsius to avoid degrading the protein structure, with typical usage levels ranging from 0.5 to 3 percent of the total formula depending on the desired intensity of the effect. The powder should first be dissolved in a small amount of warm water until fully uniform before being blended into the main batch under continuous stirring. It pairs well with other amino acids and protein complexes to reinforce the overall formula: combining it with Citrulline can support microcirculation and improve active ingredient delivery, while pairing it with Aspartic Acid is common in comprehensive hydrating blends.

For formulas requiring lighter texture or simplified dosing in smaller batches, the liquid version, Silk Amino Acids Liquid, can be added directly without pre-dissolving, making it convenient for trial runs. The powder form remains more cost-efficient for ongoing production thanks to its concentration and ease of storage.

Store the powder in a dry place away from direct sunlight, in a tightly sealed container, at room temperature, avoiding any moisture exposure that could cause clumping and reduce the ingredient's activity. Under proper storage conditions, the product retains its properties for an extended period, making it practical for maintaining production stock.
