Polyoxyethylene dioleate is a type of fatty acid that is used in cosmetics as a substance that helps to mix oil and water together. It is usually found in the form of a liquid or semi-gel with a mild smell, and it has other names like dioleoyl ethylene glycol, ethylene glycol dioleate, peg-4 dioleate, or polyethylene glycol dioleate. This ingredient can also be used as a food additive.

What is the purpose of Polyoxyethylene dioleate in personal care products? It is used for its surfactant cleansing and surfactant emulsifying characteristics. Polyoxyethylene dioleate helps clean body surfaces and helps mix liquids that don't usually mix.

Names and identifiers that we found for this substance include: Polyoxyethylene dioleate, Dioleate, "Glycols, polyethylene, dioleate", Polyethylene glycol di-(9Z)-9-octadecenyl ether, and "Poly(oxy-1,2-ethanediyl), α-(1-oxo-9-octadecenyl)-ω-((1-oxo-9-octadecenyl)oxy)-, (Z,Z)-".

What Are Surfactant Cleansing Ingredients?

Polyoxyethylene dioleate has surfactant cleansing characteristics.

Surfactant cleansing ingredients are commonly found in various cosmetics, particularly those designed for cleansing, such as shampoo, body wash, and facial cleansers. These ingredients serve several purposes, including wetting body surfaces, emulsifying or dissolving oils, and suspending dirt and grime, making them easier to remove. Surfactants generally contribute to the foaming and lathering properties of cleansing products, making them more effective in removing impurities from the skin or hair.

What Are Surfactant Emulsifying Ingredients?

Polyoxyethylene dioleate has surfactant emulsifying characteristics.

Surfactant emulsifying ingredients helps mix two liquids that do not usually mix well by reducing the surface tension of the ingredients. The emulsification process involves suspending or dispersing one liquid in a second liquid, such as oil in water or vice versa. However, these two liquids have different properties that cause them to repel each other and not mix. This is where surfactants come in, as they can reduce the liquids' surface tension and allow them to mix.

Surfactants have two ends: a hydrophilic (water-loving) head and a hydrophobic (water-repelling) tail. When added to two liquids that do not mix well, the hydrophilic head attaches to the water-based liquid, while the hydrophobic tail attaches to the oil-based liquid. This creates a stable mixture of the two liquids and allows for a smooth and even distribution of ingredients in the cosmetic product.
