Basic Information

• Chemical Name: Polyoxyethylene fatty acid ester.
• Type: Non - ionic surfactant.
• Molecular Formula: RCOO(CH₂CH₂O)nH.

Physical and Chemical Properties

• Appearance: They can be liquids, soft solids, solids or flakes.
• Solubility: The solubility properties depend on the length of the polyoxyethylene (POE) segment added to a specific fatty acid. When the number of ethylene oxide units added is less than 8, they are soluble in oil and hydrocarbon solvents. When 12 - 15 ethylene oxide units are added, they begin to be soluble in water.

Performance Characteristics

• Surface Activity: It has good surface activities such as emulsification, solubilization, wetting, dispersion, softening and antistatic properties. And it is non - toxic and non - irritating.

Main Uses

• Cosmetic Industry: It can be used as a thickener for shampoo and hair dye emulsion, a wetting agent for skin - care and moisturizing creams, a solubilizer for perfumes and essential oils, and an opacifier and pearlescent agent for cosmetics.
• Pharmaceutical Industry: Some types can be used as pharmaceutical excipients, such as oil - in - water emulsifiers, solubilizers, and bases for ointments and suppositories.
• Pesticide Industry: It can be used as an emulsifier for pesticide insecticides and herbicides.
• Paper Industry: It is used as a softener in the paper - making industry.
• Textile Industry: It can be used as a smoother and antistatic agent in textile oils.

Production Process

• The raw materials used to produce this product are fatty acids and ethylene oxide. The production method is usually the esterification reaction of fatty acids with ethylene oxide or polyethylene glycol.

Some Common Types and Their Properties

• Polyoxyl 8 Stearate: Also known as polyethylene glycol 400 monostearate, with the structural formula C₁₇H₃₅COO(CH₂CH₂)nH, where the average value of n is 8.
• Polyoxyl 40 Stearate: The average number of oxyethylene units is 40. It is a waxy, white to light tan solid, odorless or with a faint fat - like odor. It is soluble in water, alcohol, ether and acetone, but insoluble in mineral oil and vegetable oils.
