With the concern of using herbal extract, some undesirable issues like greenish color is a very critical item in producing cosmetic. The plant extracts which are normally dark green might spoil the appearance of the products if they are added in cosmetic formulation. In order to solve this problem, an activated carbon granule tea bag system was assembled and batch experiments were conducted as a mechanism to eliminate the intense colour of plant extract without affecting activities. The system was tested with different concentration of cashew leaves extract (5%, 10%, 15%, 20%, 25% and 30%) in contact with (10 g, 15 g, 20 g and 25 g) granular activated carbon (GAC) from 0 to 6 hours. The study shows that the best condition for decolorisation is 15 g GAC using 20% cashew leaves extract (CLE). Therefore, this study suggests that the tea bag system is suitable to be used for decolorisation of CLE for cosmetic application.
