OLETH-44

Description

OLETH-44 is a synthetic surfactant and emulsifier widely used in cosmetic and personal care formulations. This polyethylene glycol (PEG) ether of oleyl alcohol belongs to the broader category of ethoxylated fatty alcohols. Its structure consists of an oleyl chain attached to 44 ethylene oxide units, providing a balance between hydrophilic and lipophilic properties.

In skincare products, OLETH-44 primarily functions as an emulsifier, helping to blend oil and water-based ingredients into stable, homogeneous mixtures. It also acts as a mild surfactant, aiding in the cleansing process and enhancing the spreadability of formulations. The ingredient's high ethoxylation level contributes to its water solubility and emollient properties.

OLETH-44 is particularly valuable in creating light, non-greasy textures in moisturizers, serums, and sunscreens. It can improve the skin feel of products and may assist in the delivery of active ingredients. While generally considered safe for topical use, individuals with sensitive skin should perform patch tests as with any new skincare ingredient. As an ethoxylated compound, it may contain trace amounts of 1,4-dioxane, a potential contaminant that reputable manufacturers typically minimize through vacuum stripping processes.
