is a nonionic surfactant chemical compound widely used in various industries, especially in cosmetics and detergents. It is produced by the reaction between isotridecyl alcohol (a branched fatty alcohol) and ethylene oxide.

Structure and Properties

Structure: The structure of this compound consists of a branched hydrocarbon chain (isotridecyl) and an ethylene glycol chain. The number of ethylene glycol units in the chain can vary, and this affects the physicochemical properties of the compound.
Properties:
Emulsifier: This compound can act as an emulsifier and stabilize oil-water mixtures due to its hydrophobic part (hydrocarbon chain) and hydrophilic part (ethylene glycol chain).
Surfactant: Facilitates the reduction of surface tension between two phases and acts as a surfactant.
Softener: Gives softness and smoothness to the skin and hair.
Solvent: Soluble in many organic solvents.
Odorless and colorless: It is often odorless and colorless and is easily used in various formulations.
