Ectoine Powder (CAS 96702-03-3) – China Manufacturer & Bulk Supplier
Ectoine (CAS 96702-03-3), also known by its INCI name Ectoin, is a naturally occurring cyclic amino acid derivative first isolated from halophilic bacteria thriving in extreme environments such as salt lakes and desert soils. It can withstand extreme salinity, heat, drought, and intense UV radiation. Chemically, it is (S)-2-methyl-1,4,5,6-tetrahydropyrimidine-4-carboxylic acid (C₆H₁₀N₂O₂, molecular weight 142.16).
Ectoine is non-toxic, non-irritating, biodegradable and well tolerated by human skin and mucosal tissue. That combination of efficacy and safety is why it has become a premium active in cosmetics, dermatology, ophthalmology, and biotechnology.
Runtai Chemical supplies fermentation-derived ectoine powder at ≥99% HPLC purity, from 100 g evaluation samples to 25 kg commercial drums. Full COA, TDS, and SDS documentation is provided with every shipment.
Product Advantages
- Superior moisture retention: Ectoine binds and structures water molecules around skin cells and proteins, delivering long-lasting hydration and measurably reducing transepidermal water loss (TEWL) — with effects that persist after application stops.
- Cell and membrane protection: It shields cell membranes, proteins and DNA from environmental stressors including UV radiation, heat shock, pollution and oxidative damage, making it a strong fit for anti-pollution and sensitive-skin formulations.
- Protein and enzyme stabilisation: By preventing aggregation and denaturation, ectoine stabilises enzymes, vaccines, therapeutic proteins and diagnostic reagents during processing, storage and transport.
- Anti-inflammatory and soothing: Clinical studies show ectoine reduces inflammatory responses triggered by UV exposure and allergens, and it is well suited to sensitive, reactive and post-procedure skin.
- UV and environmental photoprotection: Acting as a molecular photoprotectant, ectoine stabilises protein and nucleic acid structures against UV-induced damage — complementing, rather than replacing, conventional UV filters.
- Naturally derived and biocompatible: Produced by microbial fermentation, ectoine is non-toxic, biodegradable and non-comedogenic, supporting natural-origin and clean-beauty claims.
