Question

What are the main characteristics of Emulsifier A-110 (Polyoxyethylene Oleate/OEO-110)?

Answer

Emulsifier A-110 (Polyoxyethylene Oleate/OEO-110) is a nonionic surfactant with natural oleic acid as the hydrophobic group and polyoxyethylene as the hydrophilic group. It integrates high-efficiency emulsification, excellent wetting and dispersion, broad chemical tolerance, superior compatibility, and low foaming tendency, making it a "versatile" emulsifying auxiliary.

Detailed Description

Emulsifier A-110 is a nonionic surfactant, appearing as a light yellow to yellow transparent oily liquid at room temperature. The length of the hydrophilic chain segment (polyoxyethylene) in its molecular structure is meticulously designed to ensure sufficient water solubility while maintaining a good balance with the oil-affinity group (derived from natural oleic acid). This enables rapid emulsification of various animal and vegetable oils, mineral oils, and organic solvents at low dosages, forming stable and fine oil-in-water (O/W) emulsions.

The core competitiveness of this product, distinguishing it from ordinary emulsifiers, lies in its "six-in-one" functional integration: high-efficiency emulsification, excellent wetting and dispersibility, broad chemical tolerance (no separation or layering in acid, alkali, or high-hardness water), superior compatibility (can be compounded with anionic, cationic, nonionic, and amphoteric surfactants in any proportion for synergistic enhancement), multifunctionality (also providing solubilization, lubrication, antistatic properties, etc.), and low foaming tendency (low foam volume and fast defoaming, especially suitable for industrial cleaning and circulating systems). This allows formulation engineers to replace multiple additives with a single product, simplifying processes and reducing overall costs.

In terms of safety and environmental protection, this product has extremely low acute oral toxicity (LD50 > 2000 mg/kg, classified as practically non-toxic), good biodegradability, is a non-hazardous substance, and has relaxed transportation and storage conditions, fully meeting the requirements of modern green chemistry for sustainable development.

Application Recommendations

Textile Industry: As a core emulsifying component in wool oils and spinning oils, it imparts good cohesion and smoothness to fibers, reducing friction and breakage during carding and spinning while providing antistatic properties.

Cosmetics and Personal Care: Used as an O/W emulsifier and solubilizer in creams, lotions, makeup removers, etc., capable of solubilizing fragrances and active ingredients, imparting a light skin feel to products.

Pesticide Formulations: An efficient emulsifier for preparing emulsifiable concentrates, oil-in-water emulsions, and microemulsions, with good emulsifying ability for various organic solvents and active ingredients, enhancing the spreading and penetration of spray liquid on target surfaces.

Metalworking Fluids: Provides dual performance of emulsification and lubrication, used in cutting fluids, grinding fluids, and rust-preventive emulsifying oils to protect tools and workpiece surfaces.

Industrial Cleaners: As a powerful degreasing component, it shows remarkable removal effect on mineral oils and animal/vegetable oils, with low foaming and easy rinsing, suitable for spray and immersion processes.

Emulsion Polymerization: Serves as the primary emulsifier in polymerization reactions of acrylates, styrene-acrylic, etc., producing polymer emulsions with uniform particle size and high stability, widely used in coatings and adhesive systems.

Precautions

  • Recommended storage temperature: 5°C to 35°C, avoid freezing or excessively high temperatures that may cause product deterioration, keep containers tightly sealed.
  • It is recommended to wear nitrile rubber gloves and protective goggles during operation, avoid prolonged direct contact with skin and eyes.
  • Can be compounded with various surfactants, but avoid contact with strong oxidizing agents.
  • After use, thoroughly wash hands and other possible contact areas. Do not eat, drink, or smoke in the work area.
  • Avoid direct discharge of the product without treatment into water bodies or soil. Waste disposal should be handled by qualified organizations in accordance with local regulations.
