Soapnut has long been known as a natural, safe, and environmentally friendly detergent. Soapnut is a rich source of saponins, which act as natural surfactants. Cleaning products prepared from soapnut extract are usually dark brown due to the influence of raw material. Accordingly, they are not suitable for consumer tastes. Therefore, research on removing the color of soapnut extract is necessary to improve the sensory value and competitiveness of cleaning products in the market.

However, color removal can significantly reduce saponin content in soapnut extract, affecting cleaning products’ washing and foaming ability. Therefore, selected color remover must reduce initial color intensity significantly without lowering saponin content. Removal of color contributes to improving product quality, expanding applicability to the cosmetic field, and increasing the economic value of soapnut.
