HYDROLYZED EXTENSIN ●
TL;DR. This ingredient functions mainly as a conditioning and moisture-binding protein hydrolysate. In hair and skin formulas, it can help form a light film, improve feel, and reduce dryness perception.
What does HYDROLYZED EXTENSIN do in a cosmetic formula?
This ingredient functions mainly as a conditioning and moisture-binding protein hydrolysate. In hair and skin formulas, it can help form a light film, improve feel, and reduce dryness perception.
Is HYDROLYZED EXTENSIN clean?
From a clean-beauty perspective, this ingredient is generally low-friction and is not a common restricted-list issue. The main checks are the carrier, preservative system, and any residual processing aids used in the raw material.
Is HYDROLYZED EXTENSIN sustainable?
This material is plant-derived and based on renewable biomass. As a peptide-rich natural hydrolysate, it is expected to be biodegradable and does not raise the persistence concerns associated with many synthetic film-formers.
Is HYDROLYZED EXTENSIN COSMOS-approved?
It can align with COSMOS-natural and COSMOS-organic when the plant source, hydrolysis method, carrier, and preservation system meet the standard. It also fits several Green Chemistry preferences, including renewable sourcing, water compatibility, and biodegradability.
How does HYDROLYZED EXTENSIN work chemically?
The molecule is a mixture of short peptides and glycopeptides generated from a hydroxyproline-rich plant cell-wall protein, with polar amino acid and sugar residues that bind water and deposit lightly on keratin. It is water-soluble, used at low conditioning levels in leave-on and rinse-off products, and needs appropriate preservation because peptide-rich aqueous materials can support microbial growth.
