Zein,CAS 9010-66-6, refers to a type of alcohol-soluble gluten protein extracted from corn. Zein appears as white to yellow powder, soluble in acetic acid, sodium lauryl sulfate, urea and strong alkali, but insoluble in water. Zein has film-forming properties, water resistance, antioxidant properties and heat resistance, and has broad application prospects in the fields of food processing, petrochemical industry, pharmaceutical manufacturing, papermaking and textile industry. We supply pharma grade, food grade and industrial grade zein powder with stable quality and full export documents.

1. Pharmaceutical industry (main applications): Enteric-coated tablets, sustained-release blocking layer, masking flavor coating; Wet granulation binder, improving tablet formation, moisture-proof and oxygen-proof, controlling drug release rate, included in pharmacopoeia as pharmaceutical excipients.
2. Food industry: Protective layer for nuts, candies, chocolate, grains, rice fortified with vitamins; Moisture-proof, anti-oxidation, brightening, anti-sticking, preventing oil seepage; Edible shiny coating.
3. Biodegradable new materials & packaging: Zein CAS 9010-66-6 for preparing biodegradable films and biodegradable coatings, replacing petroleum-based plastic coatings; Waterproof and oil-resistant coatings for paper and food packaging paper.
4. Cosmetics & personal care: Film-forming agent, protective film raw material, used in makeup, hair styling, skin protection film, locking moisture, brightening, film-forming and long-lasting makeup.
5. Inks, coatings, textiles, papermaking: Water-based ink binder, surface gloss agent; Fabric finishing agent, temporary shaping film; Ceramic adhesive.
6. Agriculture: Seed coating, protecting seeds, sustained-release agents, stress resistance and water retention.
1. Excellent film-forming property: After drying, the alcohol solution coating forms a shiny, flexible, dense and transparent film, with a natural luster on the surface.
2. Hydrophobic and oxygen-resistant, resistant to grease: The film layer is waterproof, oxygen-permeable, and resistant to oil migration, delaying the oxidation and deterioration of the contents.
3. Edible and biodegradable: Derived from natural plants, edible, degradable under composting conditions, green and sustainable.
4. Strong adhesion: Excellent binder for dry powder / wet granulation, stable in molding.
5. Certain antibacterial protection: Physical barrier against mold and bacteria, assisting in preservation.
6. Safe and compliant: FDA GRAS recognized, can be used as food and pharmaceutical excipients.
