ISOEICOSANE

Description

Isoeicosane is a synthetic hydrocarbon ingredient used in various skincare and cosmetic formulations. This colorless, odorless liquid is derived from petroleum and belongs to the family of isoparaffins. With a molecular formula of C20H42, isoeicosane is composed of a branched chain of 20 carbon atoms.

In skincare products, isoeicosane functions primarily as an emollient and texture enhancer. It imparts a smooth, silky feel to formulations while helping to reduce tackiness and greasiness. This ingredient is particularly valued for its ability to improve the spreadability of products, making them easier to apply evenly across the skin.

Isoeicosane exhibits excellent stability and is resistant to oxidation, making it suitable for use in a wide range of cosmetic applications. It is often incorporated into foundations, lip products, and moisturizers to enhance their texture and improve wear time. Additionally, isoeicosane can act as a mild occlusive agent, helping to prevent moisture loss from the skin.

While generally considered safe for use in cosmetics, individuals with sensitive skin should perform patch tests before incorporating products containing isoeicosane into their skincare routine.
