Description

Protein Hydrolyzates, Silk is a specialized, high-purity ingredient derived from the controlled enzymatic or chemical hydrolysis of silk fibroin. This compound matters for its unique blend of bioactive peptides and amino acids, offering exceptional moisturizing, film-forming, and skin-conditioning properties. It is primarily needed by manufacturers in the premium cosmetics, personal care, and pharmaceutical industries seeking natural, high-performance functional ingredients.

Application

• Cosmetic & Skincare Formulations: As a key moisturizing and anti-aging agent in serums, creams, lotions, and masks.
• Hair Care Products: To improve hair strength, elasticity, and shine in conditioners, shampoos, and treatments.
• Pharmaceutical Topicals: As a skin protectant and healing promoter in ointments and dermatological preparations.
• Biomedical Materials: For research and development in tissue engineering, wound dressings, and drug delivery systems.
• High-End Functional Foods & Nutraceuticals: As a source of bioactive peptides (subject to appropriate regulatory approval and grade).

Quality Control

Our Protein Hydrolyzates, Silk is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and microbiological quality. Certificates of Analysis (COA) documenting key parameters such as peptide profile, amino acid content, and heavy metals are available upon request. We can supply grades suitable for cosmetic (INCI compliant) and pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed after each use to prevent caking or degradation due to moisture absorption.
