SODIUM DECETH-2 CARBOXYLATE.

Insufficient Data CAS 38815-93-9 / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Sodium Deceth-2 Carboxylate is an anionic surfactant valued for its effective cleansing and foaming properties in skincare and haircare formulations. It adeptly lowers surface tension, facilitating the emulsification and removal of impurities from the skin and hair, and is notably stable across varying pH levels.

Science

Mechanism of Action

As an anionic surfactant, Sodium Deceth-2 Carboxylate functions by reducing the surface tension between immiscible components within a product. This unique property enables it to attract and encapsulate lipophilic substances, such as dirt and natural oils, from the skin and hair, allowing them to be easily rinsed away with water. Furthermore, it actively contributes to the generation and stabilization of rich foam in cleansing formulations.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) has not specifically evaluated Sodium Deceth-2 Carboxylate, although assessments exist for related ethoxylated alcohol surfactants. The Environmental Working Group (EWG) entry notes general EU GHS Hazard Labeling Codes, including potential for skin or serious eye irritation, and general warnings for genetic defects or cancer, but explicitly states 'No Data' for specific cosmetic concerns such as skin allergies, irritation, developmental and reproductive toxicity, or carcinogenicity. Its FDA status pertains to use as a food additive (PAFA) with low concern, which is not directly applicable to cosmetic applications.

Verdict

Insufficient Data

While Sodium Deceth-2 Carboxylate is an effective cleansing agent with advantageous pH-independent foam stability for formulators, the absence of a specific CIR safety review and definitive data on its irritancy and sensitization potential in cosmetic applications warrants a cautious stance.
