It may be plant- or animal-derived or made synthetically (Paula’s Choice Skincare uses the synthetic and plant-derived types). Ceteareth-25 also helps to keep ingredients soluble within a formula, allowing them to remain dispersed evenly throughout an emulsion. This ingredient is one of several ceteareths deemed safe as used in cosmetics. Concentration ranges from 1.3–10% depending on the type of formula and desired aesthetics; lower amounts may also be used, especially if ceteareth-25 is part of a blend.
