ALUMINUM ISOSTEARATES/STEARATES

Description

Aluminum Isostearates/Stearates are versatile cosmetic ingredients derived from the reaction of aluminum with isostearic and stearic acids. These compounds function primarily as opacifying agents, thickeners, and stabilizers in various skincare and cosmetic formulations. Their ability to form stable emulsions makes them valuable in creating creams, lotions, and foundations with desirable textures and consistencies.

In skincare products, Aluminum Isostearates/Stearates contribute to improved spreadability and a smooth, non-greasy feel upon application. They help create a protective barrier on the skin, which can aid in moisture retention and provide a temporary smoothing effect on the skin's surface. These ingredients are particularly useful in water-resistant formulations, such as sunscreens and long-wearing makeup products.

While generally considered safe for topical use, individuals with sensitive skin or those prone to allergies should perform patch tests before incorporating products containing these ingredients into their routine. It's important to note that Aluminum Isostearates/Stearates are not typically associated with significant skin penetration, primarily functioning on the surface level to enhance product performance and aesthetic qualities.
