Pentaerythrityl Tetrabehenate

What is Pentaerythrityl Tetrabehenate?

Pentaerythrityl tetrabehenate is a synthetic tetraester formed by reacting pentaerythritol, a polyol derived from petrochemical sources, with behenic acid, a long-chain saturated fatty acid typically sourced from vegetable oils like rapeseed. This ingredient belongs to the class of fatty acid esters commonly used in anhydrous cosmetic formulations such as lipsticks, mascaras, and solid emollients. It works by providing a waxy, non-greasy structure that enhances product integrity, allowing for smooth application and adherence. In formulations, it contributes to viscosity adjustment, helping suspend pigments and other particles while imparting a soft, conditioning feel upon skin contact. Its high melting point supports stability in stick products, preventing breakdown under temperature changes, and it aids in creating a protective barrier that supports skin's natural moisture balance without greasiness.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Binder
Helps hold solid ingredients together to form cohesive tablets, compacts, or sticks, improving pressability, integrity, and wear of the finished product.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.

Benefits

- Enhances product texture for better spreadability and wear.

- Supports skin softness and smoothness through emollient properties.

- Improves formulation stability by binding and controlling thickness.
