Elastin

Elastin (CAS 9007-58-3) is a structural protein derived from animal connective tissue, used across cosmetic, pharmaceutical, and biotech applications for its film-forming and moisture-retention properties.

Formulators source it as a functional ingredient that supports skin elasticity and surface conditioning in finished products. In personal care, it is incorporated into serums, creams, and hair treatments.

It forms a protective film on skin and hair surfaces, improving texture and reducing moisture loss. Pharmaceutical and biomedical researchers use it as a biomaterial scaffold component in tissue engineering.

In wound care applications, its biocompatibility supports cell adhesion and structural integrity. Cosmetic formulators also apply it in anti-aging product lines, where it functions as a humectant.

It binds water within the formulation matrix to maintain hydration. In biotechnology, hydrolyzed fractions are used as reference materials and research reagents for protein interaction studies and development.

The material is supplied as a lyophilized powder or liquid solution, depending on the grade and intended application. Cosmetic-grade and research-grade specifications are the most commonly available.

Purity levels vary by supplier and end-use requirement. Hydrolyzed forms are also commercially distributed, offering improved solubility for liquid formulation systems and diverse manufacturing needs.
