HYDROLYSED SILK ●
TL;DR. This ingredient functions mainly as a conditioning agent, humectant, and light film-former in hair and skin products. It helps improve slip, softness, and a smoother feel on the surface.
What does HYDROLYSED SILK do in a cosmetic formula?

Is HYDROLYSED SILK clean?
From a clean-beauty perspective, it is generally well tolerated and is not a common restricted-list issue. The main friction is that it is animal-derived, so vegan standards and some animal-welfare-focused frameworks may not accept it.
Is HYDROLYSED SILK sustainable?
This material is sourced from an animal-produced fiber and is biodegradable because it is protein-based. Sustainability depends heavily on traceability, animal-welfare practices, and whether the supply chain uses by-products or dedicated production.
Is HYDROLYSED SILK COSMOS-approved?
It can align with COSMOS-natural or COSMOS-organic formulas only when the animal-origin sourcing and processing meet the standard’s conditions. From a Green Chemistry lens, it scores well for biodegradability and mild aqueous processing, but less strongly where traceability or animal-derived sourcing is unclear.
How does HYDROLYSED SILK work chemically?
This material is a mixture of water-soluble peptides and amino acids generated by breaking down a structural animal protein into smaller fragments. It is commonly used around 0.1% to 2%, works well in mildly acidic to neutral formulas, and needs normal preservation because peptide-rich water phases can support microbial growth.
