Clay
What is Clay?
Clay is a naturally occurring, fine-grained mineral material primarily composed of hydrous aluminum phyllosilicates derived from the weathering of rocks over geological time. Sourced from deposits worldwide, it encompasses various types such as kaolinite, montmorillonite, and illite, though 'Clay' denotes a general cosmetic-grade mixture. In skincare, it falls under cleansing and masking agents, commonly featured in facial masks, scrubs, and purifying treatments. It functions through high adsorptive capacity, swelling upon water contact to form a spreadable paste that binds sebum, dirt, and surface pollutants. Upon drying, it contracts, aiding mechanical removal of debris while providing a mattifying effect and thickening texture in formulations for better application control.
