Polyoxyethylene stearate Usage And Synthesis
Chemical PropertiesWaxy, light-tan solid; nearly odorless. Congealing range 39–45C. Soluble in water, alcohol, ether, and acetone; insoluble in mineral and vegetable oils.
UsesPolyoxyethylene stearate is an emulsifier and antifoaming agent used in processed foods, fruit jellies, and sauces.
Usespolyethylene glycol monostearate is an emulsifier.
UsesPEG-5 stearate is listed as particularly applicable for hand and body lotions and creams.
UsesPegosperse(R) 400 MS is a multifunctional surface active agent suggested for use in cosmetic formulations, household products, lubricants, textile chemicals, polishes and paper.
UsesPegosperse(R) 1500 MS is a mixture of polyethylene glycol esters. It is compatible with lipophilic compounds due to a higher free fatty acid content. Suggested applications: cosmetic formulations, lubricants.
UsesPegosperse(R) 1750 MS is a high molecular weight, high HLB surface active agent suggested for use in cosmetic formulations (emulsifier, viscosity modifier) and in lubricants (emulsifier).
DefinitionPolyoxyethylene stearate is a mixture of the monoand diesters of stearic acid and mixed polyoxyethylene diols having an average polymer length of 7.5 oxyethylene units.
Brand nameMyrj 53 (ICI Americas).
General DescriptionPolyoxyethylene (40) stearate is a neutral surfactant.
Safety ProfileVery slightly toxic by ingestion. Questionable carcinogen with experimental tumorigenic data. Experimental reproductive effects. When heated to decomposition it emits acrid smoke and irritating fumes. See also other polyethylene glycol monostearate entries and POLYETHYLENE GLYCOL.
