Aluminum Hydroxide

Description

Aluminum Hydroxide is a versatile inorganic compound widely used in skincare and cosmetic formulations. This white, amorphous solid acts as a multifunctional ingredient, serving primarily as an opacifying agent and pH adjuster. Its ability to scatter light effectively makes it valuable in products where opacity or a matte finish is desired, such as foundations and sunscreens.

In skincare, Aluminum Hydroxide plays a crucial role in stabilizing formulations, particularly in emulsions and suspensions. It helps prevent separation of ingredients and maintains product consistency over time. As a pH buffer, it assists in maintaining the optimal acidity level of products, which is essential for both product efficacy and skin compatibility.

Aluminum Hydroxide also functions as a mild astringent, potentially benefiting oily or acne-prone skin by temporarily tightening pores and reducing excess sebum. Its gentle nature makes it suitable for sensitive skin formulations. In sun protection products, it enhances the effectiveness of physical UV filters like titanium dioxide and zinc oxide by improving their dispersion and coverage on the skin. While generally considered safe for topical use, individuals with aluminum sensitivities should exercise caution.
