DISODIUM LAURAMIDO MEA-SULFOSUCCINATE.

Valuable CAS 25882-44-4 / CLEANSING, FOAMING, SKIN CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING, SURFACTANT - HYDROTROPE

Disodium Lauramido MEA-Sulfosuccinate is a mild anionic surfactant distinguished by its effective cleansing and foaming properties. Its large molecular structure is designed to limit skin penetration, while simultaneously offering beneficial skin conditioning. This versatile ingredient is well-suited for a broad spectrum of precision skincare formulations.

Cleansing Agent Foam Booster Foaming Agent Hydrotrope Skin Conditioning Agent

Science

Mechanism of Action

This anionic surfactant primarily functions by reducing the surface tension of water, facilitating the emulsification and subsequent removal of oils and dirt from the skin. It effectively acts as a cleansing agent, foam booster, and foaming agent, while also providing hydrotropic and skin conditioning benefits. Its comparatively large molecular structure inherently restricts deeper epidermal penetration, contributing to its gentler profile.

Dusting Analysis

Not commonly dusted

As a primary surfactant and functional ingredient, Disodium Lauramido MEA-Sulfosuccinate is not typically used for 'dusting' or minimal inclusion; its efficacy is dependent on its active concentration.

Stability

Optimal stability is observed within a pH range of 5.0 to 9.0. As an ester, it is susceptible to hydrolysis in strongly acidic or alkaline environments. It maintains full compatibility with other anionic, non-ionic, and amphoteric surfactants. Prolonged exposure to high temperatures should be avoided, particularly when handling its concentrated paste form (30-45% active content), to prevent degradation or irreversible changes. Reversible cloudiness or crystallization may occur upon storage without impacting quality.

7%
Sensitization risk Unknown

The CIR Expert Panel has affirmed its safety for cosmetic use, provided formulations are non-irritating. Permitted concentrations are up to 3% in leave-on products and up to 7% in rinse-off applications. Potential for skin and eye irritation exists if not correctly formulated, underscoring the importance of precise concentration and excipient selection. Its larger molecular size is associated with reduced skin penetration.
