Silk Protein Extract Liquid Form – Oil Soluble

Oil-soluble silk protein extract, derived from hydrolyzed silk proteins like fibroin and sericin, serves as a conditioning and moisturizing agent in cosmetics. Its low molecular weight (2,000-4,000 Da) enables better absorption, film-forming, and a luxurious silky feel on skin and hair.​ Skincare Benefits Enhances deep hydration, elasticity, and firmness while forming a protective barrier without greasiness. Ideal for oil-based creams, lotions, serums, anhydrous balms, and primers to plump skin, smooth texture, and improve moisture retention.​ Haircare Benefits Reduces breakage, boosts manageability, shine, and softness by coating strands and binding to keratin. Commonly used in shampoos, conditioners, treatments, and pomades at 2-5% levels.​ Formulation Notes Oil-soluble form (e.g., Cocoyl Hydrolyzed Silk) suits anhydrous or oil-phase products; add directly at 2-5%. Stable as clear/hazy liquid, store cool and dry; compatible with most surfactants.
