Nanometer acidified aliphatic ester and application thereof

The invention discloses nanometer acidified aliphatic ester. Firstly, aliphatic ester is prepared, the aliphatic ester is prepared from, by weight, 9-15 parts of palmitic acid, 4-8 parts of unsaturated linoleic acid, 63-70 parts of unsaturated oleic acid and 3-5 parts of octadecanoic acid, the aliphatic ester is subjected to nanocrystallization and then subjected to ozonization, the grain size iscontrolled to be 100 nanometers or smaller, the acid value is controlled not to be higher than 30 mg/kg, and the nanometer acidified aliphatic ester is obtained. The nanometer acidified aliphatic ester can be used for treating bromhidrosis. The clinic curative effect and safety of externally use of the nanometer acidified aliphatic ester for treating bromhidrosis are observed. The conclusion is that the nanometer acidified aliphatic ester is safe and effective when externally used for treating bromhidrosis. In addition, the nanometer acidified aliphatic ester can also be used for treating psoriasis, and the curative e
