Emulsifier MOA-3B is a high-purity, multifunctional nonionic surfactant, with excellent emulsifying ability, outstanding wetting and dispersing properties, superior chemical stability, and mild use characteristics as its core advantages.
Detailed Description
Emulsifier MOA-3B, with the chemical name fatty alcohol polyoxyethylene (3) ether (C12~14 carbon chain), belongs to nonionic surfactants. It is also known as AEO-3, laureth-3, or Laureth-3. Its appearance is a colorless to slightly yellow transparent liquid, with high active matter content and high product purity, ensuring stable and reliable performance during use.
This product has a moderate hydrophilic-lipophilic balance (HLB) value, exhibiting excellent emulsifying stability for various oil phase systems, especially suitable for the preparation of water-in-oil emulsions. At the same time, MOA-3B can effectively reduce interfacial tension, promote liquid spreading on solid surfaces, have a significant dispersing and stabilizing effect on solid particles, and significantly enhance the solubility of poorly soluble substances in aqueous or oil phase systems, providing greater flexibility for formulation design.
In terms of chemical stability, MOA-3B maintains good performance stability in both acidic and alkaline environments, and has excellent tolerance to hard water, broadening the scope of application of the product. The product pH is close to neutral, making it relatively mild and friendly to substrates and operators. In addition, the product has a closed-cup flash point above 150°C and is not classified as a flammable liquid.
