Science
Mechanism of Action
This ingredient primarily functions by creating a hydrophobic, non-occlusive film on the skin's surface. This film effectively minimizes transepidermal water loss (TEWL), resulting in softer and smoother skin by maintaining its condition. Beyond its skin benefits, it acts as a PEG-free emulsion stabilizer, particularly effective in water-in-oil (W/O) systems, a dispersant, and a thickening agent, thereby contributing to product consistency and stability.

Stability
Exhibits good thermal stability, making it suitable for various formulations. It functions effectively as a PEG-free emulsifier, providing excellent emulsion stabilization properties even at low concentrations, typically between 2% and 3%, making it ideal for W/O creams and lotions. It can also be utilized to formulate low viscosity W/O lotions with a light, non-oily feel, and W/O emulsions with high silicone oil content.

Safety
Safety Profile
ETHYLHEXYL POLYHYDROXYSTEARATE has not been specifically reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel. However, the Environmental Working Group (EWG) Skin Deep database rates it with a low hazard for common concerns such as cancer, allergies, immunotoxicity, and developmental & reproductive toxicity. Closely related ingredients, such as Ethylhexyl Hydroxystearate and Ethylhexyl Stearoyl Polyhydroxystearate, are considered non-comedogenic, non-toxic, non-sensitizing, and 'Irritant Free', with regulatory bodies like the EU and FDA permitting their use without restrictions.
