Problems solved by technology

At present, the Chinese herbal medicine cosmetics prepared by licorice extract (flavonoids) are generally made of various medicinal plants, and the preparation process is complicated. In addition, the content of flavonoids in licorice extract is low, so that it prevents the formation of melanin, anti- Oxygen, anti-allergic, prevent skin aging and effectively remove superoxide ions, etc. are not ideal

Abstract

The invention relates to a liquorice whitening moisturizing lotion and a preparation method thereof, which belong to technology of preparing cosmetics by natural substances. The liquorice whitening moisturizing lotion is prepared by an effective active component of a liquorice cell extract with liquorice whitening effect, and comprises octodecyl alcohol, white oil, monoglyceride, an emulsifier-tween 80, span 80, glycerol, triethanolamine, a lilac compound, 2-methyl-4-isothiazoline-3-ketone, 5-chloro-2-methyl-4-isothiazoline-3-ketone and the effective active component of the liquorice cell extract. The preparation method comprises the combined extraction process of an effective liquorice component and the step of preparing the liquorice whitening moisturizing lotion from components such as the effective liquorice component, deionized water and the like. The liquorice cell whitening moisturizing lotion has high content of effective components, can better inhibit the formation of melanin, and achieve good whitening effect; in addition, the product does not contain other pharmaceutical ingredients, and has simple extraction and preparation processes.

Description

technical field [0001] The invention relates to a licorice whitening lotion and a preparation method thereof, which is a whitening lotion prepared from effective active ingredients of licorice cell extracts, and belongs to the technology of preparing cosmetics with natural products. Background technique [0002] Licorice (Glycyrrhiza uralensis Fisch.) is a perennial herb of the leguminous family and one of the most commonly used traditional Chinese medicines. It has always been said that "ten directions and nine herbs". Licorice is not only a traditional Chinese medicine, but also widely used in modern medicine, food, cosmetics and other fields. There is a huge demand for licorice in the market. At present, wild licorice resources are on the verge of exhaustion. One of the most effective methods to solve the shortage of licorice resources is to produce valuable active substances (active ingredients of licorice cell extract) by means of cell culture. The main active ingredie...
