Used primarily as a multifunctional ester solvent in cosmetic and personal care formulations. Its unique structure allows it to act as a skin-conditioning agent, providing emollient properties that enhance product spreadability and leave a non-greasy feel on the skin. Commonly found in lotions, creams, and sunscreens, it helps improve the solubility of other ingredients while stabilizing emulsions. Due to its lipophilic nature with hydrophilic segments, it also serves as a penetration enhancer, aiding the delivery of active ingredients into the skin. Additionally, it is employed in some industrial applications as a plasticizer or lubricity additive in low-volatility systems.
