Alumina

Description

Alumina, also known as aluminum oxide (Al2O3), is a versatile and widely used ingredient in skincare and cosmetic formulations. This white, crystalline powder is prized for its multifunctional properties, serving as both an abrasive agent and a thickening/stabilizing component in various products.

In skincare, alumina acts as a gentle physical exfoliant, helping to remove dead skin cells and improve skin texture without causing excessive irritation. Its fine particle size allows for effective exfoliation while minimizing the risk of microtears in the skin. Additionally, alumina functions as an opacifying agent, enhancing the appearance and texture of creams, lotions, and foundations.

The ingredient's absorbent properties make it valuable in oil control formulations, helping to reduce shine and manage excess sebum production. Alumina also exhibits antimicrobial characteristics, potentially contributing to the preservation of skincare products and supporting overall skin health.

From a formulation perspective, alumina aids in improving the stability and viscosity of emulsions, ensuring consistent product texture and performance. Its inert nature makes it compatible with a wide range of other skincare ingredients, allowing for versatile application across various product types.
