POTASSIUM LAURETH-5 CARBOXYLATE.

Valuable / SURFACTANT - CLEANSING

Potassium Laureth-5 Carboxylate is a sophisticated multi-functional ingredient primarily employed as a surfactant, cleansing agent, emulsifier, and foaming agent. It proficiently aids in impurity removal by facilitating the blend of oil and water, concurrently enhancing product stability and lather quality.

Summary

Cleansing Emulsifying Surfactant Foaming

Science

Mechanism of Action

This ingredient operates by effectively lowering the surface tension of liquids, thereby enabling the dispersion and removal of oil-based impurities from the skin and hair. Its unique carboxyl group allows it to demonstrate properties characteristic of both non-ionic and anionic surfactants. As an emulsifier, it stabilizes complex formulations by forming an interface between immiscible phases, preventing separation. Furthermore, it is recognized for its capacity to generate a rich, stable foam, contributing to an elevated sensory experience in cleansing applications.

Stability

This ingredient exhibits robust stability across a wide range of conditions, including hard water, acidic, and highly alkaline environments. It is noted to maintain greater stability under high alkaline conditions compared to some alternative surfactants and shows compatibility with strong acids. Foaming performance and stability are generally uninfluenced by pH variations.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Potassium Laureth-5 Carboxylate has not undergone a formal safety assessment by the Cosmetic Ingredient Review (CIR) Expert Panel or the SCCS. General toxicity concerns for cancer, allergies & immunotoxicity, and developmental & reproductive toxicity are rated low by EWG. However, there are significant concerns regarding potential contamination with byproducts of ethoxylation, specifically Ethylene Oxide and 1,4-Dioxane. Products incorporating this ingredient can achieve EWG VERIFIED™ status, provided they adhere to stringent use restrictions and warnings established through EWG's evaluation of company-specific data.
