CIR Review: Based on similar structures, the CIR Expert Panel determined that the alkyl PEG ether compounds, including the Deceth ingredients could be reviewed together. Developmental and reproductive toxicity studies as well as mutagenicity data were all negative for these compounds. These compounds can irritate the skin. Therefore, the CIR Expert Panel concluded that the Deceth ingredients, as well as the other alkyl PEG ether ingredients were safe as used when formulated to be nonirritating.

Small amounts of 1,4-dioxane, a by-product of ethoxylation, may be found in the Deceth ingredients. The potential presence of this material is well known and can be controlled through purification steps to remove it from the ingredients before blending into cosmetic formulations.

More information about 1,4-dioxane.

The Deceth ingredients may be used in cosmetics and personal care products marketed in Europe according to the general provisions of the Cosmetics Directive of the European Union.

Deceth ingredients are polyethylene glycol ethers of Decyl alcohol that contain repeating ethylene oxide units. These ingredients are useful in cosmetics and personal care products as surfactant – emulsifying agents.
