Overview
Decanol Polyoxyethylene Ether is a nonionic surfactant synthesized by the ethoxylation of decyl alcohol. It belongs to the alcohol ethoxylates family, characterized by a hydrophobic decyl chain and a hydrophilic polyoxyethylene group. The number of ethylene oxide (EO) units (denoted as 'n') determines its hydrophilic-lipophilic balance (HLB), making it versatile for formulations requiring specific solubility and surface activity. It is biodegradable and considered environmentally friendlier than many ionic surfactants.
Physical and Chemical Properties
The compound typically appears as a colorless to pale yellow viscous liquid or soft paste, depending on the degree of ethoxylation. Its solubility in water increases with higher EO units, while lower EO variants are more oil-soluble. Key properties include low foam generation, stability in acidic and alkaline conditions, and compatibility with other surfactants. The HLB range (typically 10-14) makes it suitable for both emulsification and detergency applications. Thermal stability is moderate, with decomposition occurring above 200°C.
Main Applications
In industrial settings, it serves as a wetting agent in textile processing (dyeing and scouring) and as an emulsifier in agricultural formulations. Its mildness also makes it suitable for cosmetic products like shampoos and skin cleansers. Household applications include liquid detergents and hard-surface cleaners, where it enhances grease removal. In institutional cleaning, it is valued for its low residue and compatibility with disinfectants. The specific EO chain length determines niche uses, e.g., shorter chains for degreasing, longer chains for solubilization.
Safety and Storage
Classified as a mild irritant, it requires standard personal protective equipment (gloves, goggles) during handling. While not highly toxic, prolonged skin contact may cause dryness or irritation. No significant environmental hazards are reported, but local regulations for surfactant discharge should be followed. Storage recommendations include keeping containers tightly sealed in well-ventilated areas at temperatures below 40°C. Shelf life is typically 2 years when stored properly. Incompatibilities include strong oxidizers, which may degrade the ethoxylate chains.
B2B Procurement Guide
Buyers should specify the average EO units (e.g., POE-6, POE-10) required for their applications, as this directly affects performance. Technical datasheets should provide HLB values, active matter content (usually 99% min), and pH range (neutral). Bulk purchases (drums or isotanks) offer cost savings, with prices influenced by crude oil derivatives' market trends. Quality certifications like ISO 9001 or ECOCERT (for cosmetics-grade) add assurance. Lead times vary; domestic suppliers in chemical hubs (e.g., Shanghai, Ludwigshafen) often stock common variants.
