Manufacturing method of hydrogel cosmetic film

Abstract

The invention discloses a production method of a hydrogel skin caring film, and the production method comprises the following steps in sequence: (A) compounding: preparing feed liquid from carrageenan, potassium citrate, citric acid and preservative raw materials with deionized water; (B) pouring: pouring the feed liquid into a film mold which is a bottom support constituting an external package;(C) freezing: freezing the feed solution in the mold; (D) secondary pouring: pouring essence liquid into the mold, wherein the essence liquid contains thermally-instable active substances and high polymers that are not easily released by hydrogel; and (E) packaging: carrying out heat sealing and packaging. The production method disclosed by the invention has the advantages of high production efficiency, low contamination risk during production, and low energy consumption. Since the product contains skin caring components that are not suitable to be added during hydrogel film formation process, the quality and efficacy of the product are improved.

Description

technical field [0001] The invention relates to a manufacturing method of a cosmetic product, in particular to a manufacturing method of a hydrogel cosmetic patch. Background technique [0002] At present, the hydrogel beauty film based on the polymer hydrophilic gel is more and more favored by consumers because of its advantages of no carrier, all natural, no barrier, strong water locking effect and environmental protection, etc. There is a tendency to replace non-woven beauty stickers. For this reason, many cosmetic film manufacturers have invested in research and development of hydrogel cosmetic films, so that hydrogel cosmetic films can have more effects. [0003] For example, Chinese patent CN101444963 discloses a method for manufacturing crystal beauty film, which mainly consists of the following steps: A, ingredients; B, coating; C, freezing; D, cutting; E, loading into the bottom bracket; F, Bagging. However, this method has the following disadvantages: 1. There w...

Problems solved by technology

However, this method has the following disadvantages: 1. There will be residual materials in the coating and cutting process, which need to be reworked, and the rework process increases the risk of bacterial contamination and energy consumption, which is not conducive to environmental protection and low carbon; 2. The film layer needs to be completely frozen in the freezing process, otherwise it will affect the cutting effect and cause flow phenomenon, and the long freezing time will lead to time-consuming and energy-consuming, which is not conducive to improving production efficiency and environmental protection; 3. The packaging process is general Manual operation not only has the risk of bacterial contamination, but also is not conducive to improving production efficiency

This method also requires manual operation during packaging, which also has the risk of bacterial contamination and is not conducive to improving production efficiency.
