Science
Mechanism of Action
This glyceryl diester functions primarily as a surface lubricant, reducing friction and enhancing the skin's texture for a visibly smoother and softer appearance. It acts as an effective emollient, contributing to overall skin conditioning.

The Formula
Formulation
Stability
Nominally a 1,3-diglyceride, this compound is prone to isomerization into the potentially biologically active 1,2-diester form. Precise formulation and rigorous testing are essential to manage the 1,2-diester content below levels that could induce epidermal hyperplasia. General glyceryl ester stability can also be influenced by pH conditions.
Safety
Safety Profile
The CIR Expert Panel considers Glyceryl Diisopalmitate safe for cosmetic use, provided the content of the biologically active 1,2-diester form is not sufficiently high to cause epidermal hyperplasia. Given that the proportion of these isomers is often unknown, each specific product formulation requires thorough examination and testing during development to confirm the absence of this effect. Diglycerides, as a class, are generally recognized as safe (GRAS) by the FDA for certain food applications.

Verdict
A valuable emollient for enhancing skin smoothness, but its safe incorporation into formulations requires stringent quality control and testing to manage the potentially biologically active 1,2-diester content.
