Abstract

The invention relates to a preparation method of a curcumin flexible liposome cream. The preparation method comprises the following three steps: preparing a curcumin flexible liposome, preparing freeze-dried powder from the curcumin flexible liposome, and preparing a curcumin flexible liposome cream. According to the preparation method disclosed by the invention, a curcumin liposome and a flexible liposome are prepared by virtue of a thin film dispersion process, and emulsible pastes of the curcumin liposome and the flexible liposome are prepared by virtue of an emulsification process so as to ensure that an optimal prescription is screened out and is subjected to stability evaluation and sensory evaluation, the utilization degree of curcumin can be improved, the emulsible pastes can be finer and more lubricant, and more choices can be provided in the application of cosmeceuticals in the future.

Description

technical field [0001] The invention relates to a preparation method of curcumin flexible liposome cream, which belongs to the field of chemistry. Background technique [0002] 1 Properties and functions of curcumin [0003] Curcumin is a yellow pigment extracted from the rhizomes of plants such as ginger. It is a polyphenolic substance with a small relative molecular weight, and it is generally considered to be the most effective ingredient in turmeric. Its structure is as follows: figure 1 shown. Physical properties: orange-yellow powder, slightly bitter taste, melting point 183°. Insoluble in water and ether, soluble in ethanol and propylene glycol, easily soluble in glacial acetic acid and alkali solution, reddish-brown in alkaline, yellow in neutral and acidic. It has strong stability to reducing agents and has coloring properties, but it is not sensitive to light and heat. Sensitive to iron ions. [0004] Curcumin has anti-inflammatory, anti-oxidation, anti-cance...
