Pourquoi sourcer au Japon

UNESCO-listed Tomioka Silk Mill anchors the heritage; remaining sericulture cooperatives prioritise high-grade fibroin for cosmetic and biomedical channels.

Spec clé

Hydrolysed molecular weight typically 200–5,000 Da; glycine and alanine dominate amino-acid profile; beta-sheet content drives film-forming properties.

Produit fini typique

À propos de cet ingrédient

The structural protein of silk (~70-75% of cocoon mass), with hydrolysed forms used in cosmetics and biomedical applications. Distinct from sericin (the gum coating), fibroin's beta-sheet crystal structure gives it superior film-forming and tensile properties; medical-grade fibroin scaffolds are emerging in wound dressings and tissue engineering. Japanese sericulture in Gunma, Nagano, and Saitama supplies cocoon stock; specialty processors hydrolyse fibroin for cosmetic ingredient grades. Often paired with sericin in moisture-and-strengthening positioning.
