Bentonite

Description

Bentonite is a naturally occurring clay mineral derived from volcanic ash, renowned for its exceptional absorption and detoxifying properties. This versatile ingredient is composed primarily of montmorillonite, a type of smectite clay with a unique layered structure. When hydrated, bentonite swells significantly, forming a colloidal suspension with a high surface area and strong negative charge.

In skincare formulations, bentonite acts as a powerful adsorbent, drawing out impurities, excess oils, and toxins from the skin. Its ability to form a protective barrier on the skin's surface helps to soothe irritation and reduce inflammation. Bentonite also exhibits mild exfoliating properties, gently removing dead skin cells and promoting cellular turnover.

The mineral content of bentonite, including silica, magnesium, and calcium, provides additional benefits for skin health. These elements can help improve skin elasticity, promote healing, and support the skin's natural barrier function. Bentonite's pH-balancing effects make it suitable for various skin types, particularly oily and acne-prone skin.

When formulating with bentonite, it's crucial to consider its thickening properties and potential for altering product texture. Proper hydration and dispersion techniques are essential to maximize its efficacy in skincare products.
