GLYCERETH-7 TRIACETATE.

Insufficient Data CAS 57569-76-3 / SKIN CONDITIONING - EMOLLIENT, SOLVENT

Glycereth-7 Triacetate is a synthetic ester lauded for its multifaceted role in skincare, delivering hydration and a distinctive silky skin feel. It acts as both a humectant and an emollient, alongside its crucial functions as a solvent and coupling agent in complex formulations.

Humectant Emollient Solvent Coupling Agent O/W Emulsifier Wetting Agent Dispersant

Science

Mechanism of Action

Glycereth-7 Triacetate primarily functions as a synthetic humectant, efficiently drawing and retaining moisture to enhance skin hydration and impart a soft, silky texture. It also serves as an emollient, smoothing the skin and contributing a unique, slightly dry finish. Beyond skin benefits, it acts as a solvent, dissolving various cosmetic esters and oils, particularly valuable in sunscreens, and as a coupling agent to stabilize hydro-alcoholic systems by solubilizing difficult-to-dissolve esters. The ingredient further helps reduce tackiness in carbomer gels, improves gloss and lubricity without excessive oiliness, and acts as an O/W emulsifier and dispersant for pigmented products.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded 'insufficient data' for the safety assessment of Glycerin Ethoxylates (the broader group including Glycereth-7, the foundation for Glycereth-7 Triacetate), citing concerns over low-level reactions observed in Human Repeated Insult Patch Test (HRIPT) studies. Specific safety data for Glycereth-7 Triacetate itself is limited. As an ethoxylated chemical, there is a potential for trace contamination by carcinogenic impurities such as ethylene oxide and 1,4-dioxane, along with polycyclic aromatic hydrocarbons (PAHs) and heavy metals (e.g., lead, cobalt, nickel, cadmium, arsenic).

Verdict

Insufficient Data

Glycereth-7 Triacetate offers versatile humectant, emollient, and formulation benefits, but its safety assessment is hampered by insufficient data from the CIR and concerns regarding potential ethoxylated impurities.
