Science
Mechanism of Action
This ingredient operates as a skin conditioning agent and emollient. It forms a protective, non-occlusive film on the skin's surface, which helps to maintain hydration by reducing transepidermal water loss, thereby contributing to a softer and smoother epidermal texture.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Distearyl Citrate, along with related alkyl citrate esters, is safe when used in cosmetic products at current practices and concentrations. This assessment is supported by studies, including a multigenerational dietary administration of an ester mixture up to 9.5%, which showed no reproductive or developmental effects. CIR also found that at typical cosmetic concentrations, this ingredient does not cause eye irritation, skin irritation, or allergic skin reactions.
