SODIUM LAURETH-14 CARBOXYLATE.

Questionable CAS 33939-64-9 / CLEANSING, FOAMING, SURFACTANT - CLEANSING

Sodium Laureth-14 Carboxylate is an anionic surfactant primarily utilized for its robust cleansing, foaming, and emulsifying capabilities. It effectively reduces surface tension to remove impurities, making it a functional component in various rinse-off cosmetic formulations like facial cleansers.

Summary

Cleansing Foaming Surfactant - Cleansing

Science

Mechanism of Action

As an anionic surfactant, Sodium Laureth-14 Carboxylate operates by decreasing the surface tension between immiscible liquids, such as oils and water, thereby allowing them to mix. This action facilitates the emulsification and removal of lipid-soluble and particulate impurities from skin and hair surfaces, enabling thorough cleansing and efficient lather generation.

CIR Status
Not reviewed
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has not evaluated Sodium Laureth-14 Carboxylate. There are notable concerns regarding potential contamination with impurities such as ethylene oxide and 1,4-dioxane, attributed to its synthesis as a PEG derivative. However, the Environmental Working Group (EWG) assesses its overall hazard as 'LOW' concerning cancer, allergies & immunotoxicity, and developmental & reproductive toxicity. INCIDecoder also reports low irritancy.
