The two kinds of Mukuroji lowered surface tension of water of 73 mN m-1 to 42 mN m-1, which is nearly equal to SDS of 41 mN m-1. Dispersion stability of the Mukuroji solutions was almost equal to that of SDS for less than 1 h. Emulsion stability of the Mukuroji solutions was slightly lower than that of SDS and kept for an enough period as well as SDS solution. Detergency tests using cloths showed that Mukuroji can be used as a detergent, however coloring matter contained in natural Mukuroji pericarps stained cotton cloth and lowered the detergency. The redeposition tests showed that Mukuroji reduced the redeposition of polyester cloth compared with SDS., 論文},
