Product Introduction
Silk Peptide Powder is derived from natural silk fibers and provides a peptide- and amino-acid-based ingredient profile for cosmetic and personal care formulations. Through controlled processing, the silk protein is prepared into a fine powder suitable for ingredient evaluation and formulation development.
In cosmetics and personal care products, silk-derived peptide ingredients can be used in skin- and hair-conditioning formulations, including creams, serums, facial masks, shampoos, conditioners, and other personal care products.
Its formulation performance depends on factors such as peptide characteristics, concentration, processing conditions, and compatibility with other ingredients. For B2B customers, Angelbio provides product specifications, samples, quality documentation, and technical support to assist with ingredient evaluation and product development.
