Science
Mechanism of Action
This ingredient works by forming a protective, occlusive film on the skin's surface, which effectively reduces transepidermal water loss. This barrier helps to lock in moisture, leading to improved lubrication, conditioning, and a smoother, softer skin feel. Beyond its direct skin benefits, its emulsifying properties stabilize oil-in-water mixtures, while its thickening action enhances the body and dispersibility of other components within a formulation.

Safety
Safety Profile
The CIR Expert Panel has deemed Glyceryl Diester ingredients, including Glyceryl Di-Hydroxystearate, safe for use in cosmetics under current practices and concentrations, provided that 1,2-diester content does not lead to epidermal hyperplasia. Diglycerides, which encompass Glyceryl Di-Hydroxystearate, also hold FDA approval for indirect food additive applications. While no specific maximum concentration for this exact ingredient was identified, related diesters have been safely incorporated at concentrations up to 43% (e.g., Glyceryl Diisostearate in lipsticks) and 2.3% (e.g., Glyceryl Distearate in eye products).
