Dipentaerythrityl Tri-Polyhydroxystearate

Dipentaerythrityl Tri-Polyhydroxystearate is a high–molecular weight fatty-acid ester used mainly as an emollient/structuring and dispersing agent in color cosmetics and creams, typically at low to moderate percentages. As a non-volatile, non-reactive lipid-like material, it has a low likelihood of causing stinging or barrier disruption in patch testing and routine use, with irritation primarily limited to rare idiosyncratic reactions or impurity-related sensitivity. For patient safety in severely reactive skin, I score it as very gentle rather than inert because complete non-irritancy cannot be guaranteed across compromised barriers. Safety Notes: Dipentaerythrityl Tri-Polyhydroxystearate is used primarily as an oil-phase structurant/viscosity builder and pigment/wax dispersant in anhydrous or high-oil systems (e.g., lipsticks, lip oils, balms, stick foundations/sunscreens), where it can function as a key rheology modifier. In mass-market emulsions (leave-on creams/lotions, tinted moisturizers) it is often present at low levels (~0.1–2%) as a secondary stabilizer/texture aid, while the highest consumer-available levels are seen in anhydrous color cosmetics and heavy sticks/balms where it may reach ~8–12% to provide structure, payoff, and suspension.
