Applications
1. Emollient for Skin Care: 2-Ethylhexyl stearate (CAS 22047-49-0) is a branched-chain emollient ester used in skin creams, lotions, and sunscreens, where it moisturises and conditions the skin with good spreading and a non-occlusive feel.
2. Colour Cosmetics Application: In foundations, lipsticks, and eye products, it improves application and texture, giving a smooth, even finish while carrying the colour and oil phase through the product.
3. Solvent, Carrier, and Wetting Agent: The ester also functions as a solvent, carrying agent, and wetting agent in cosmetic formulations, helping disperse and carry the other ingredients in the system.
4. Metalworking and Industrial Lubrication: It is used as a lubricant in the metalworking industry and for lubrication in plastics processing, where an ester-based lubricant is preferred.
5. Plasticizer For Resins And Polymers: The ester acts as a plasticizer, including use as a resin plasticizer in hair styling resins, and it is applied in plastics and PVC formulations.
Quality Assurance
Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.
Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
