Problems solved by technology

[0003] Most of the whitening products currently on the market achieve the purpose of whitening and cosmetic modification by adding titanium dioxide. Titanium dioxide is used to form a thin film on the skin to improve skin tone, but skin whitening is instant whitening, which cannot achieve real skin whitening. purpose, and if used for a long time, it is easy to cause clogged pores
Pearl powder is used in beauty products to play a whitening role, but most of the pearl powder with a larger particle size is added to beauty products, and the active ingredients cannot be better absorbed by the skin, which affects the beauty effect

Abstract

The invention discloses a preparation method of whitening pearl additive for cosmetics and relates to the technical field of beauty and cosmetics. The preparation method disclosed by the invention comprises the following steps: controlling a pearl powder particle size to be 100nm or less by adopting a nano pulverization technology, and extracting and purifying pomegranate bark to obtain polyphenol-enriched extract by adopting a microwave-ultrasound assisted low eutectic reagent extraction technology and a two aqueous phase extraction and CO2 counter-current extraction technology, and finally,uniformly mixing pearl powder, glycerin and polyphenol extract by adopting an emulsifying mixing technology, thereby obtaining the whitening pearl additive. According to the whitening pearl additive prepared by the method disclosed by the invention, the pearl powder is small in particle size, adsorption of skin on active ingredients is promoted, the cosmetic has a smooth hand feeling, and the antioxidant effect of the cosmetic is effectively enhanced. In addition, the whitening pearl additive is non-irritating and excellent in skin affinity and can be widely applied to cosmetics such as liquidfoundation, cream, sun cream, essence lotion and the like.

Description

technical field [0001] The invention relates to the technical field of beauty and makeup, in particular to a method for preparing a pearl whitening additive for cosmetics. Background technique [0002] In recent years, with the acceleration of people's life and work rhythm and the intensification of environmental pollution, people are facing more and more skin problems, especially dull skin and pigmentation have become common problems, and whitening cosmetics have therefore become skin care products. A hot spot in the development field. As people's consumption concepts become increasingly mature, consumers pay more attention to whitening cosmetics not only on their efficacy, but also on their safety. [0003] Most of the whitening products currently on the market achieve the purpose of whitening and cosmetic modification by adding titanium dioxide. Titanium dioxide is used to form a thin film on the skin to improve skin tone, but skin whitening is instant whitening, which c...
