Dipentaerythrityl Hexahydroxystearate

Dipentaerythrityl hexahydroxystearate is a high–molecular weight ester used mainly as an emollient/texture agent in leave-on products, typically at low-to-moderate percentages, and it is not an acid, surfactant, or biologically active irritant. Available safety and patch-test experience for similar fatty acid esters suggests low inherent irritation, though very reactive or eczema-prone skin can still flare to otherwise “bland” lipids in compromised barrier states. Given its non-volatile, non-fragrant profile and low reactivity but acknowledging compromised-skin vulnerability, it best fits a very gentle score. Safety Notes: Dipentaerythrityl Hexahydroxystearate is used as an emollient/texture and viscosity modifier in anhydrous and W/O systems (e.g., lip products, sticks, balms, rich creams), where it can appear at very low levels (~0.05–0.3%) as a secondary structuring/feel additive. In higher-structure consumer products (lipsticks, lip balms, deodorant/skin sticks, barrier balms, and some high-wax “cold cream” style formulas), it is used at multi-percent levels, with observed OTC market maxima around ~8% when it functions as a primary consistency/film-forming emollient. It is predominantly a leave-on ingredient; rinse-off usage exists but is typically lower due to cost and limited need for heavy structuring.
