Poly(oxy-1,2-ethanediyl), .alpha.-hydro-.omega.-hydroxy-, mono-C12-14-alkyl ethers, phosphates
CAS 68511-37-5
What Is Poly(oxy-1,2-ethanediyl), .alpha.-hydro-.omega.-hydroxy-, mono-C12-14-alkyl ethers, phosphates?
This synthetic ingredient is a specialized polymer used primarily in industrial and household cleaning products. Consumers may encounter it in laundry detergents, dish soaps, and surface cleaners where it helps with grease removal and foam control. While not a fragrance ingredient itself, it plays a supporting role in product formulations by improving the performance of scent delivery systems in cleaning products.
Safety Profile
GENERALLY SAFEWhat Does Poly(oxy-1,2-ethanediyl), .alpha.-hydro-.omega.-hydroxy-, mono-C12-14-alkyl ethers, phosphates Smell Like?
This material is essentially odorless in its pure form, functioning as a surfactant rather than a fragrance component. In formulations, it may carry slight chemical notes reminiscent of clean alcohols or faint waxy undertones, but these are typically masked by the primary fragrance oils in finished products. Its olfactory impact is negligible compared to its functional properties.
Chemistry, Properties & Perfumer Guide
The Chemistry
This compound belongs to the class of alkyl ether phosphates, synthesized through the ethoxylation of C12-14 fatty alcohols followed by phosphorylation. The resulting amphiphilic molecules contain both hydrophilic (polyoxyethylene and phosphate groups) and hydrophobic (alkyl chains) regions. This structure enables excellent surfactant properties, particularly in hard water conditions where the phosphate groups provide superior cleaning performance compared to non-ionic surfactants alone.

Tip: Use as a base surfactant system component rather than a fragrance material.
Alternatives & Comparisons
More common anionic surfactant with similar cleaning properties but different foam characteristics.
Amphoteric surfactant offering milder properties for personal care applications.
Safety, Regulatory & Sustainability
⚠ Regulatory Disclaimer
General reference only. Consult current IFRA Standards Library before formulating.
IFRA Status
Not restricted by IFRA as it is not a fragrance material.
GHS Classification
RIFM Assessment
Not evaluated by RIFM as it is not a fragrance material.
Sustainability
As a petrochemical-derived surfactant, this material raises typical environmental concerns associated with synthetic surfactants. However, its high efficiency at low usage levels and biodegradability through standard wastewater treatment help mitigate environmental impact. Some manufacturers offer bio-based versions using renewable feedstocks for improved sustainability profiles.
