Chemical Name: Polyethylene glycol monocetyl ether; Polyethylene glycol monolauryl ether; Polyethylene glycol monooleyl ether; Polyethylene glycol monostearyl ether. Stability and Storage Conditions: Polyoxyethylene alkyl ethers are chemically stable in strongly acidic or alkaline conditions. The presence of strong electrolytes may, however, adversely affect the physical stability of emulsions containing polyoxyethylene alkyl ethers.On storage, polyoxyethylene alkyl ethers can undergo autoxidation, resulting in the formation of peroxides with an increase in acidity. Many commercially available grades are thus supplied with added antioxidants. Typically, a mixture of 0.01% butylated hydroxyanisole and 0.005% citric acid is used for this purpose. Polyoxyethylene alkyl ethers should be stored in an airtight container, in a cool, dry place. Source and Preparation: Polyoxyethylene alkyl ethers are prepared by the condensation of linear fatty alcohols
