Science
Mechanism of Action
This ingredient functions by forming a barrier on the skin's surface, effectively filling microscopic voids and impeding transepidermal water loss, which results in superior hydration and a refined skin texture. Beyond its emollient capabilities, it also acts as a viscosity controlling agent, allowing for precise adjustment of product thickness, and contributes to the overall film-forming characteristics of cosmetic formulations.

The Formula
Formulation
Stability
Pentaerythrityl Tetrabehenate exhibits extremely poor solubility in water, estimated at 6.3 x 10^-11 g/L at 25 °C across a pH range of 1-10. As an ester, it is inherently oil-soluble. While a specific optimal pH range for its stability is not detailed, esters typically maintain stability over a wide pH spectrum, with hydrolysis generally occurring only under extreme acidic or alkaline conditions.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed Pentaerythrityl Tetrabehenate, along with 15 other related pentaerythrityl tetraester compounds, and concluded their safety for use in cosmetic formulations under current practices and concentrations. A single universal maximum concentration across all product types is not explicitly defined in the available summaries, with safety based on reported 'as used' concentrations.
