MAGNESIUM ALUMINUM SILICATE

Description

Magnesium Aluminum Silicate (MAS) is a naturally occurring mineral compound derived from purified clay. This versatile ingredient is widely used in cosmetic and pharmaceutical formulations due to its multifunctional properties. MAS is composed of a complex mixture of magnesium, aluminum, silicon, and oxygen atoms arranged in a layered structure.

In skincare products, MAS primarily functions as a thickening agent and stabilizer, enhancing the texture and consistency of creams, lotions, and gels. Its ability to form a colloidal network in aqueous systems helps suspend other ingredients and prevent separation. MAS also exhibits oil-absorbing properties, making it beneficial in mattifying products and those designed for oily skin types.

The ingredient is generally considered safe for topical use and is non-comedogenic, meaning it doesn't clog pores. MAS has a high degree of chemical inertness, which contributes to its compatibility with a wide range of other cosmetic ingredients. Its stability across various pH levels makes it suitable for diverse formulations.

While MAS is not typically associated with direct skin benefits, its role in improving product texture and stability indirectly contributes to the overall efficacy and user experience of skincare formulations.
