BIODEGRADABILITY
Hydrolyzed silk demonstrates excellent biodegradability both in vitro and in vivo, meaning it naturally breaks down after being absorbed by the skin without accumulating in the body, thereby avoiding metabolic burden. This characteristic positions it as a safe and eco-friendly cosmetic additive, aligning with modern consumer demand for green and healthy lifestyles.
EXCELLENT BIOCOMPATIBILITY
Hydrolyzed silk, a scleroprotein structurally analogous to human skin and tissues, exhibits high affinity for hair and skin surfaces. This biocompatibility facilitates enhanced skin absorption in cosmetic formulations while minimizing the risk of irritation and allergic reactions. Extensive research demonstrates that when cells derived from diverse human tissues—including epithelial cells, fibroblasts, keratinocytes, and bone marrow cells—are cultured on pure silk fibroin membranes, all cell types adhere, spread, and form intercellular connections. Notably, the majority of these cells remain viable on the membranes, further substantiating the excellent biocompatibility of hydrolyzed silk.
REPAIRING EFFECT ON HAIR
Hydrolyzed silk demonstrates adhesive properties on hair under humid conditions, enhancing smoothness and moisture retention. Incorporated into permanent perming products, silk proteins
prolong styling durability and facilitate the formation of curls and waves. Notably, its affinity for bleached or chemically damaged hair—resulting from cold wave treatments utilizing thioglycolic
acid or bromate salt solutions—enables effective mitigation of chemical trauma when applied in optimal concentrations. This dual functionality has cemented hydrolyzed silk as a widely adopted ingredient in haircare formulations, particularly for repairing compromised hair fibers.

advantage
1, Reduce the irritancy of surfactants: Through chicken embryo experiments, it has been confirmed that hydrolyzed silk can reduce the irritancy of foaming agents commonly used in products such as shampoo, shower gel, and facial cleanser, namely surfactants.
1.0%K12 1.0%K12+1.0% hydrolyzed silk
2, Moisturizing effect: Hydrolyzed silk is derived from the hydrolysis of natural silk, and the peptides formed after hydrolysis have excellent moisturizing ability, which can be applied in hair care and hair care products.
