Deoiling fluffy washing-free hair drying spray and preparation method thereof

The invention discloses a deoiling fluffy washing-free hair drying spray and a preparation method thereof. The preparation method comprises the following steps: preparing rice starch into starch primary pulp, and then adding amylase for enzymolysis to obtain a starch particle core; the method comprises the following steps: mixing starch particle cores and high-activity polyether polyol, and reacting with an isocyanate substance to obtain oil absorption particles; the oil-absorbing particles are used as important components to prepare the oil-removing washing-free hair-drying spray. After the deoiling fluffy washing-free hair drying spray is sprayed and used, the oil absorption effect is good, and particles are rapidly dissipated; various coagulation, gathering and agglomeration phenomena are not easy to occur, a refraction effect is basically not generated, and a whitening phenomenon is avoided. 本发明公开了一种去油蓬松免洗干发喷雾及其制备方法。该制备方法包括如下步骤：将大米淀粉先预制淀粉原浆，然后加入淀粉酶酶解，得到淀粉颗粒核心；将淀粉颗粒核心、高活性聚醚多元醇先混合后，和异氰酸酯物质反应，得到吸油颗粒；以该吸油颗粒为重
