What is ISOPROPYL ISOSTEARATE used for?

Isopropyl Isostearate has many uses in the personal care and cosmetic industry. It is a great emollient that provides intense moisturization and hydration to the skin. It also forms a protective barrier that helps prevent water loss, keeping the skin soft and supple. Because it is lightweight and non-greasy, Isopropyl Isostearate does not feel heavy on the surface of the skin and lets it breathe. In products like creams, serums, and lotions, this ingredient improves the spreadability and absorption to allow for an easier application and a smooth finish. Isopropyl Isostearate is also added to makeup formulations such as foundations, lipsticks, and eyeshadows, where it enhances the blend-ability and adherence of the products.

Origin

Isopropyl Isostearate is typically made by esterifying isostearic acid with isopropyl alcohol. This process involves combining the acid and alcohol in the presence of a catalyst, resulting in the formation of Isopropyl Isostearate and water. The reaction is then followed by purification steps to obtain the desired product.
