Collagen, CAS#9007-34-5
Appearance: It is a white or off-white free-flowing fine powder, tasteless and odorless, obtained by enzymatic hydrolysis of animal connective tissue.
Solubility: Soluble in warm water, forms a uniform colloidal solution; insoluble in ethanol, acetone and other organic solvents.
Stability & pH Performance: The pH value of its aqueous solution is 5.0–7.0. It maintains stable activity under mild temperature conditions; high temperature above 60℃ will cause denaturation and change its functional properties. It is stable under weak acid and neutral conditions.
Basic Function Features: It is a natural macromolecular protein composed of amino acids such as glycine, proline and hydroxyproline. It has good water retention, film-forming property and biocompatibility, and is easy to be absorbed by human body after hydrolysis.
Collagen, characterized by the general formula (C₁₀H₁₆N₂O₃)ₙ, presents as white to off-white fine powder. It dissolves in warm water to form a transparent colloidal solution, and will precipitate out when adding ethanol or acetone. Its aqueous solution is nearly neutral. The substance is a structural protein extracted from animal skin, bone and scale. Hydrolyzed collagen peptide has smaller molecular weight and better absorption performance. It is widely used as nutritional raw material, moisturizing agent and texture improver in food, health care and cosmetic industries.
