Bamboo charcoal powder is produced from bamboo through high-temperature carbonization. Its fine, porous structure provides excellent adsorption and oil-control effects. These characteristics make bamboo charcoal powder versatile for a wide range of cosmetic applications. Furthermore, its natural and eco-friendly properties align with modern consumers' preference for natural and sustainable products. Specifically, bamboo charcoal powder can serve as a substitute for chemical pigments commonly used in cosmetic products. Technically, the ultrafine texture of micro-nanosized bamboo charcoal powder allows it to be easily blended with various cosmetic ingredients, adding new functionality and market appeal to these products.
