Science
Mechanism of Action
This ingredient functions by providing exogenous lipids that adhere to the skin, effectively filling gaps within intercorneocyte clusters to bolster the skin barrier. It creates a hydrophobic film on the skin's surface, which significantly reduces transepidermal water loss (TEWL), resulting in more moisturized and softer skin. Additionally, Ethylhexyl Isostearate serves as an effective solvent, facilitating the even distribution of other active ingredients and improving their delivery to the skin.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed Ethylhexyl Isostearate, along with other alkyl esters, as safe for use in cosmetics under current practices and concentrations, provided formulations are designed to be non-irritating. Stearate esters generally have a safe usage history across a broad range of concentrations.
