Characterisation of Sugarcane Bagasse-Based Activated Carbon to Assess Its Suitability for Skincare Formulations

Abstract

The growing interest in natural and sustainable skincare products requires innovative strategies. This trend is driven by increasing consumer demand for products that are environmentally sustainable and skin-friendly. This study examines the characteristics of sugarcane bagasse-based activated carbon (SBAC) to evaluate its potential use in skincare formulations. Sugarcane bagasse was carbonised at 700°C and subsequently chemically activated with 30% (w/w) phosphoric acid (H3PO4) to enhance its adsorptive properties. The activated carbon was analysed for its physicochemical properties, including carbon content, moisture content, ash content, sulphur content, pH value, adsorption capacity, and removal efficiency. The results revealed a carbon content of 97.07%, moisture at 1.77%, ash content at 2.93%, sulphur content at 0.25%, a neutral pH of 7.04, an adsorption capacity of 148.80 mg/g, and a removal efficiency of 98.35% for methylene blue. The characteristics suggest potential benefits in skincare products, including enhanced impurity removal, reduced skin irritation, and improved skin clarity. The neutral pH of 7.04 and the low sulphur content of 0.25% indicate that this formulation is suitable for use on sensitive skin. The SBAC demonstrated significant adsorption capacity (148.80 mg/g) and removal efficiency (98.35%) for methylene blue, highlighting its potential for detoxification and purification of the skin. The findings suggest that SBAC serves as a viable natural ingredient for skincare formulations, offering a sustainable and effective alternative for skincare applications.
