SODIUM C11-15 PARETH-7 CARBOXYLATE.

Questionable CAS 68603-23-6 / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Sodium C11-15 Pareth-7 Carboxylate is a synthetic surfactant and emulsifier frequently found in various personal care formulations. Its primary role involves reducing surface tension to facilitate cleansing and stabilizing oil-in-water emulsions, though its safety profile presents several areas of concern.

Summary

Cleansing Emulsifying Surfactant

Science

Mechanism of Action

This ingredient functions primarily as an anionic surfactant, effectively lowering the surface tension of aqueous systems. This action enables the thorough mixing of oil and water, facilitating the detachment and removal of lipidic and particulate impurities from skin and hair surfaces. Additionally, it acts as an emulsifier, stabilizing finely dispersed mixtures of immiscible phases, thereby contributing to product consistency and performance.

The Cosmetic Ingredient Review (CIR) Expert Panel has not evaluated Sodium C11-15 Pareth-7 Carboxylate. The Environmental Working Group (EWG) permits its use in VERIFIED™ products only under strict restrictions due to potential contamination by toxic impurities, and lists 'some' level of concern for genetic defects, cancer, reproductive toxicity, and respiratory/skin/eye irritation. While some sources suggest it is generally non-irritating, there is a notable likelihood of irritation, with the risk amplified when combined with other challenging ingredients, potentially leading to inflammation or dryness.

Verdict

Questionable

Given its unreviewed safety status, potential for toxic contamination, and noted likelihood of irritation alongside broader health concerns, Sodium C11-15 Pareth-7 Carboxylate is a questionable ingredient for formulations targeting precision skincare.
