식물성 왁스의 탈색 방법에서, 유기 용매에 용해된 식물성 왁스 원료를 압력 하에 식물성 왁스 원료에 함유된 안료에 대한 리젝션이 왁스 성분에 대한 리젝션보다 더 높은 나노여과 막과 접촉시켜, 탈색된 왁스를 함유하는 투과액을 제공하고, 안료를 잔류액에 농축시켰다. In the method for decolorizing a vegetable wax, a vegetable wax raw material dissolved in an organic solvent is contacted under pressure with a nanofiltration membrane having a higher rejection for a pigment, contained in the vegetable wax raw material, than for the wax components, providing a permeate containing decolorized wax and enriching the pigment in the retentate.
