TRIDECETH-20.

Valuable CAS 24938-91-8 (Generic) / CLEANSING, SURFACTANT - EMULSIFYING

TRIDECETH-20 is a polyethylene glycol ether of tridecyl alcohol, functioning as a multi-purpose surfactant. It is precisely engineered to act as a cleansing, emulsifying, and solubilizing agent within cosmetic formulations, offering broad compatibility across various skin types.

Science

As a non-ionic polyethylene glycol ether, TRIDECETH-20 effectively reduces the surface tension between different phases in a formulation. This allows it to stabilize oil-in-water or water-in-oil emulsions, facilitate the dissolution of oil-soluble ingredients into aqueous solutions, and aid in the removal of impurities from the skin surface.

Stability

TRIDECETH-20, as an ethoxylated compound, may contain trace amounts of 1,4-dioxane as a processing byproduct, which can be minimized through rigorous purification protocols. Similar to related ingredients, it is susceptible to oxidative degradation, with stability influenced by factors such as temperature, concentration, iron impurities, and oxygen exposure.


Safety

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that TRIDECETH-20 is safe for use in cosmetic products when formulated to be non-irritating. It possesses a potential for irritation if not properly formulated. The FDA permits its use as an indirect food additive. While EWG notes low concerns for cancer, allergies & immunotoxicity, and developmental toxicity, it highlights a high concern for contamination from ethylene oxide and 1,4-dioxane.
