Essence with whitening and moisturizing functions and preparation method thereof

Abstract

The invention discloses a preparation method of essence with whitening and moisturizing functions, which comprises the following steps: adding deionized water, pearl powder, a humectant, essence, xylitol, caprolactam-based silicone oil, trehalose, citric acid and niacin amine into a first reaction kettle, stirring to obtain a clear and transparent mixed solution, then adding a thickening agent, and sprinkling into the mixed solution; dissolved mixed liquid is guided into the filtering tank through the feeding pipe, the mixed liquid entering the filtering tank falls onto the filtering plate and enters the filtering cylinder through the flow guide holes, undissolved impurities in the mixed liquid can be filtered and separated through the filtering holes in the filtering cylinder, meanwhile, the adjusting motor drives the multiple filtering shafts to rotate, scraping plates on the filtering shafts rotate, and therefore the impurities in the mixed liquid can be filtered and separated. Impurities on the inner wall of the filter cartridge are scraped in time; guiding the separated mixed solution to a second reaction kettle through a liquid discharge pipe for continuous reaction to obtain a solution; and S2, adding the nymphaea hybrid extract and the preservative into the solution in the step S2, and stirring.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to an essence with a whitening and moisturizing function and a preparation method thereof.

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems, the object of the present invention is to provide a kind of essence with whitening and moisturizing function and its preparation method, which can improve the filter device on the original basis, so that the filter cartridge can pass through the scraper when filtering. The rotation enables the scraper to scrape off the impurities on the inner wall of the filter cartridge in time, thereby ensuring the overall filtration efficiency and effectively preventing clogging. Moreover, due to the reduction of clogging, the overall production efficiency can be effectively improved. And reduce the replacement frequency of the filter cartridge
