Collagen

Collagen (CAS 9007-34-5) is a structural protein derived from animal connective tissue, available commercially under names including Avitene and Tachotop. It functions as a film-former, moisturizer, and rheology modifier across food, pharmaceutical, and cosmetic manufacturing.

Sourced primarily from bovine, porcine, or marine origins, the raw material choice directly affects regulatory status and end-market suitability. In food production, collagen is processed into edible casings for sausages and meat products.

It is also hydrolyzed into peptides for functional nutrition products such as protein supplements and fortified beverages. Cosmetic formulators incorporate it into skin creams, serums, and hair conditioners to improve moisture retention.

Pharmaceutical manufacturers use fibrillar collagen formats as hemostatic agents and wound dressings in surgical applications. It also serves as a matrix material in drug delivery systems and tissue engineering scaffolds.

Its biocompatibility is a primary procurement driver for medical applications. Collagen is supplied as powder, granules, solution, and membrane or sponge formats depending on the intended application requirements.

Standard grades include food-grade, USP, and Ph.Eur., with additional distinctions by source species and hydrolysis level. Buyers should confirm molecular weight range and origin certification when evaluating suppliers.

Particularly important are halal, kosher, or non-bovine status certifications. These factors ensure the material meets the specific regulatory and dietary needs of the target consumer market and industrial application.
