Hydrolyzed collagen

Hydrolyzed collagen (CAS 92113-31-0, EC 295-635-5) is a protein-derived ingredient produced by enzymatic or acid hydrolysis of animal collagen, yielding low-molecular-weight peptides and amino acids. It is commercially available under trade names including Colatron, Crotein SPO, Crotein SPA, Lexein X 350, and Gelita-Sol C. It carries no assigned E-code.

In personal care formulations, hydrolyzed collagen binds moisture to the skin and hair surface through hygroscopic peptide chains, improving elasticity and reducing transepidermal water loss. In food and nutritional products, it functions as a protein supplement and antioxidant stabilizer, where its free amino acid content helps scavenge reactive oxygen species and extend shelf life in processed formats.

Hydrolyzed collagen is supplied in food-grade and cosmetic-grade forms, typically as a spray-dried powder or concentrated liquid. Compliance documentation commonly covers REACH registration, FCC specifications, and Halal or Kosher certification depending on the collagen source. Packaging formats vary by supplier and application grade.
