Overview
Oleyl alcohol emulsifier is a fatty alcohol derivative derived from oleic acid, primarily used as a non-ionic surfactant. Its molecular structure includes a long hydrophobic chain and a hydrophilic hydroxyl group, enabling it to stabilize oil-in-water emulsions effectively. In industrial and consumer applications, it serves as a key ingredient in formulations requiring smooth textures, such as lotions, creams, and lubricants. Its biocompatibility and mildness make it suitable for sensitive skin products.
Physical and Chemical Properties
Oleyl alcohol emulsifier exhibits a low melting point (13-19°C) and high boiling point (330-360°C), reflecting its stability under moderate heat. It is less dense than water (0.85 g/cm³) and dissolves readily in organic solvents but not in water. Its non-ionic nature allows compatibility with a wide pH range, reducing the risk of precipitation in acidic or alkaline formulations. The emulsifier’s viscosity and clarity can vary slightly depending on the degree of ethoxylation.
Main Applications
In cosmetics, oleyl alcohol emulsifier is prized for its ability to create stable emulsions in moisturizers, hair conditioners, and sunscreens. It imparts a silky feel without greasiness. Pharmaceuticals leverage its solubilizing properties for topical creams and ointments. Industrially, it acts as a lubricant additive and textile softener. Its role in agrochemical formulations aids pesticide dispersion.
Safety and Storage
While oleyl alcohol emulsifier is low in toxicity, proper handling is essential. Use in well-ventilated areas and avoid prolonged skin contact to prevent irritation. Storage should be in tightly sealed containers to prevent oxidation. Regulatory bodies like the FDA and EU Cosmetics Directive approve its use in specified concentrations. Always consult Safety Data Sheets (SDS) for workplace guidelines.
B2B Procurement Guide
When sourcing oleyl alcohol emulsifier, prioritize suppliers with transparent quality control, such as batch-specific Certificates of Analysis (CoA). Key parameters to test include purity, peroxide value, and moisture content. Bulk procurement (e.g., drums or totes) often reduces costs. Negotiate contracts with clauses for consistent quality and delivery timelines. Sustainable sourcing options (e.g., RSPO-certified oleyl alcohol) may appeal to eco-conscious buyers.
