LAURETH-4

LAURETH-4: what it is
LAURETH-4, also known as laureth-4, is an ethoxylated compound linked to a lauryl chain. Its structure combines an oil-attracting portion with one that interacts more readily with water, a feature that matters to how it behaves in cosmetic preparations.
The number 4 distinguishes this member of the laureth family: it refers to the degree of ethoxylation associated with the name, not to the amount placed in a product. The substance may also be described as a C12 alcohol with four ethoxylate units, wording that separates it from laureths with other numbers.
LAURETH-4: what it does in cosmetics
In cleansing products, LAURETH-4 helps water meet oily residues during rinsing. In practical terms, this supports a formula as it spreads and removes oil, dirt, and other components that do not dissolve well in water alone.
As an emulsifier, it helps keep water-based and oily components more evenly distributed in a preparation. It can also be part of fragrance compositions and, in hair products, its antistatic role relates to reducing the static electricity that makes dry strands fly away; these functions are not a specific treatment for skin or hair.
