MEA PPG-6 LAURETH-7 CARBOXYLATE.

Valuable / CLEANSING, SURFACTANT - CLEANSING

MEA PPG-6 LAURETH-7 CARBOXYLATE is a precision surfactant and emulsifier designed to reduce surface tension, effectively aiding in cleansing by mixing water with oils, sebum, and dirt. Its dual nature allows for the creation and stabilization of finely dispersed oil and water mixtures, enhancing formulation elegance and efficacy.

Summary

emulsifying surfactant cleansing foaming

Science

Mechanism of Action

This ingredient functions by lowering the surface tension between substances, which is critical for thoroughly blending water with oils, sebum, and environmental debris for effective cleansing. Its molecular structure contains both hydrophilic (water-loving) and lipophilic (oil-loving) components, enabling it to act as an emulsifier. This allows for the formation and stabilization of homogenous oil-in-water or water-in-oil emulsions, ensuring product stability and smooth application. Furthermore, it contributes to desirable foam quality and can offer moisturizing benefits within a formulation.

Stability

MEA PPG-6 LAURETH-7 CARBOXYLATE demonstrates robust physico-chemical stability, maintaining its integrity effectively even at lower pH levels. Similar carboxylate surfactants exhibit performance flexibility based on pH, acting nonionic in acidic environments and as hard water-tolerant anionic agents in alkaline conditions.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) panel has determined MEA PPG-6 LAURETH-7 CARBOXYLATE to be safe for use, provided it is formulated to be non-irritating. A broader CIR assessment covering related Alkyl PEG/PPG Ethers similarly concluded their safety under non-irritating formulation conditions. However, it is important to note that polyethylene glycol-based surfactants, including the Laureth-7 component, may potentially contain trace impurities such as 1,4-dioxane and ethylene oxide, which are recognized as potential carcinogens. The Scientific Committee on Consumer Safety (SCCS) was unable to fully evaluate the safe use of Laureth-7 in cosmetic products as of 2011 due to a lack of comprehensive pharmacological and toxicological data.
