Science
Mechanism of Action
This ingredient operates by forming a durable, protective film on the skin's surface. This film effectively minimizes transepidermal water loss, thereby enhancing skin hydration and maintaining the skin's good condition. Its adhesive properties improve product longevity and adherence, while its pigment-dispersing capabilities contribute to even cosmetic application. As an occlusive agent, it provides a protective barrier, and its water-insoluble nature is key to boosting waterproof attributes in formulations.

It exhibits good heat stability and excellent aging resistance, ensuring formulation integrity over time. Its inherent stability makes it particularly suitable for sensitive-skin formulations.
Safety
Safety Profile
While the specific combination 'GLYCERYL DIISOSTEARATE/HYDROGENATED ROSINATE' lacks a standalone CIR assessment, its individual components have been reviewed. Glyceryl Diisostearate has shown variable use concentrations in lipsticks (from 43% down to 0.54%), and Glyceryl Hydrogenated Rosinate demonstrated no sensitization at a 10% concentration in a mixture during clinical tests. It is generally considered well-tolerated for both rinse-off and leave-on products at appropriate concentrations, though patch tests are recommended for individuals with sensitive skin. Glyceryl Hydrogenated Rosinate is also recognized by the FDA as a food contact substance.
