Abstract

The invention provides a preparation method of an alpinia japonica extract for caring hair or skin, and a personal care product composition containing the alpinia japonica extract. The preparation method comprises the following steps: 1) crushing and press-squeezing the alpinia japonica to obtain residue and juice of the alpinia japonica; 2) adding water to the alpinia japonica residue with uniform mixing and allowing the mixture to stand for 30-45 min; 3) collecting water soluble substances with rest alpinia japonica residue for later use; 4) mixing the water soluble substance with the alpinia japonica juice, performing supercritical CO2 extraction and collecting an extract; 5) adding water to the alpinia japonica residue to decoct the alpinia japonica residue for 1-2 h, and filtering the decoction to collect an extract liquid; and 6) mixing the extract and the extract liquid. The preparation method is mild in operation conditions. The alpinia japonica extract has excellent effects of whitening and moisturizing skin when being used in skin care products, and also has excellent hair caring effect when being used in hair caring products.
