Freezing-dried and non-freezing-dried hydroquinone mono-propionate beautifying effect nanometer emulsion and its preparation method

Abstract

The invention discloses freeze-drying, non freeze-drying hydroquinone monocarbonylate nano-emulsions for beauty treatment and a process for preparation. The freeze-drying nano-emulsions contain the following materials by weight proportion: hydroquinone monocarbonylate 0.5-4 parts, vitamin E 0.2-2.0 parts, isopropyl myristate 8-18 parts, octanoic acid capric acid triacetate 0.1-1.0 parts, octanoic acid capric acid glycedol 32-40 parts, polyglycerol fatty acid esters 10-14 parts, double distilled water 35-45 parts, manna sugar 15-25 parts, aminoacetic acid1-6 parts. The non freeze-drying nano-emulsions contain the following materials by weight proportion: monocarbonylate 0.5-4 parts, vitamin E 0.2-2.0 parts, isopropyl myristate 8-18 parts, octanoic acid capric acid triacetate 0.1-1.0 parts, octanoic acid capric acid glycedol 32-40 parts, polyglycerol fatty acid esters 10-14 parts, double distilled water 35-45 parts. The invention has the advantages of simple preparation method, easy practical operation and industrialization, stable quality of products, prolonged storage time, and effective and quick preparation. The whole process for preparion can be finished in less than 30 minutes. No special apparatus is needed. Great progress has been made in saving energy and materials, and reducing the environmental contamination.

Description

technical field [0001] The present invention relates to the preparation of biopharmaceutical preparation technology applied to skin pigmented diseases and cosmetic whitening and spot-removing products after improvement, in particular to a freeze-dried and non-freeze-dried hydroquinone monopropionate beauty effect nanoemulsion and its preparation method. Background technique [0002] With the development of society, the advancement of science and technology, and the continuous improvement of people's material, cultural, and spiritual living standards, beauty care is not only the pursuit of all beauty lovers, but also an important part of people's pursuit of high-quality and high-grade life in modern society.
