Description

Product Overview

Ectoine (also written Ectoin; INCI: Ectoine; CAS 96702-03-3) is a natural
osmolyte — a cyclic amino acid derivative produced industrially by fermentation. In cosmetic formulation it is
used as a moisturising and protective active, valued for its ability to bind water around cells
and to help skin cope with environmental stress.

Aogubio supplies Ectoine as a cosmetic-grade powder in bulk, with batch documentation for export markets.
