Science
Mechanism of Action
Functioning as a lubricant on the skin's surface, Ethylhexyl Stearate forms a hydrophobic barrier that effectively minimizes transepidermal water loss and locks in essential moisture. Beyond hydration, it acts as a proficient solvent for other ingredients, optimizing their distribution and enhancing the overall consistency of a product. It serves as a carrier, potentially improving skin hydration, mitigating irritation, and facilitating the penetration of active compounds.

Key findings
- 01 Human Repeated Insult Patch Tests (HRIPT) demonstrated Ethylhexyl Stearate to be non-sensitizing at concentrations up to 25.9% when used in a lip gloss formulation, and up to 38.8% in an eyebrow pencil formulation.
Transparency
Dusting Analysis
As an oil-soluble emollient and solvent, Ethylhexyl Stearate does not exhibit characteristics associated with dusting concerns in formulations.
The Formula
Formulation
Stability
Ethylhexyl Stearate is noted for its stability, with the raw material typically presenting a neutral pH.
Synergies
- Enhances the spreadability and uniform distribution of other ingredients within a formulation.
- Improves the penetration of active ingredients due to its carrier and solvent properties.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that stearate esters, including Ethylhexyl Stearate, are safe for use in cosmetics under current practices and concentrations, a conclusion reaffirmed in 2003, provided formulations are non-irritating. The FDA lists it as an active ingredient under TSCA.
