Description

Sericin is a natural globular protein derived from silk, primarily known for its unique film-forming, moisturizing, and biocompatible properties. This versatile biopolymer is gaining significant traction across various high-value industries due to its ability to enhance product performance and safety. Key sectors that utilize sericin include the cosmetics and personal care industry for skin and hair formulations, the biomedical field for wound dressings and tissue engineering, and the textile sector as a functional finishing agent.

Application

• Cosmetics & Personal Care: Used as a natural moisturizer, film-forming agent, and anti-aging component in creams, lotions, serums, and hair care products for its ability to retain moisture and improve skin elasticity.
• Biomedical & Pharmaceuticals: Employed in wound healing dressings, drug delivery systems, and as a scaffold material in tissue engineering due to its excellent biocompatibility and biodegradability.
• Functional Textiles: Applied as a natural finishing agent to impart antimicrobial, UV-protective, and moisturizing properties to fabrics.
• Food & Nutraceuticals: Explored as an edible coating to extend food shelf life and as a potential functional ingredient in dietary supplements.
• Advanced Materials: Incorporated into biodegradable films, hydrogels, and composites for packaging and other material science applications.
