SODIUM TRIDECETH-12 CARBOXYLATE.

Insufficient Data CAS 61757-59-3 / 68891-17-8 / CLEANSING, FOAMING, SURFACTANT - CLEANSING

An anionic surfactant celebrated for its exceptional cleansing and foaming capabilities, Sodium Trideceth-12 Carboxylate effectively reduces surface tension to emulsify lipid-based impurities, facilitating their efficient removal. Its unique molecular architecture ensures stable, high-volume foam, rendering it a valuable component in various rinse-off personal care formulations.

Summary

Cleansing Agent Surfactant Foaming Agent Emulsifier

Science

Mechanism of Action

This ingredient functions as an anionic surfactant, precisely lowering the surface tension at the interface between skin, water, and impurities. This action effectively solubilizes and encapsulates hydrophobic substances like sebum and environmental pollutants, enabling their thorough rinse-off. The distinctive C13 tridecyl chain combined with a high degree of ethoxylation contributes to its significant hydrophilicity and the generation of a stable, high-volume foam, enhancing the user experience. Furthermore, it acts as an emulsifier, stabilizing complex formulations by promoting the homogeneous dispersion of immiscible oil and water phases, preventing product separation. In hair care applications, it also contributes to improved wet combability and reduction of static electricity.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

A specific safety assessment by the Cosmetic Ingredient Review (CIR) for Sodium Trideceth-12 Carboxylate is not available. While chemically related surfactants like Sodium Laureth Sulfate are generally considered safe when formulated to be non-irritating, the Environmental Working Group (EWG) raises significant concerns regarding potential contamination with by-products such as ethylene oxide and 1,4-dioxane. This leads EWG to restrict its use in EWG VERIFIED™ products without robust purity substantiation. No specific SCCS opinion or FDA status for this exact ingredient has been identified.

Verdict

Insufficient Data

While effective as a cleansing and foaming agent with a low reported irritation profile, the absence of a specific CIR review and noted contamination concerns by EWG indicate insufficient data for a definitive endorsement without further safety substantiation.
