Natural makeup powders are makeup products made with natural ingredients that provide a light, natural look and are kinder to sensitive skin. Natural Makeup Powder is gradually becoming a market hotspot as a natural, healthy, and environmentally friendly makeup choice. A cosmetic freeze dryer is a low-temperature freezing, vacuum sublimation stabilization drying equipment, with the preservation of natural makeup powder nutrients, color, body shape, and other basic unchanged. In this paper, we will focus on the application of cosmetic freeze dryers in the freeze-drying processing of natural makeup powder, and discuss its advantages and technical characteristics.
A cosmetic freeze dryer is a kind of equipment that uses freezing and vacuum drying technology to remove water after freezing liquid substances. In the production of natural color cosmetics powder, cosmetic freeze dryer has the following advantages:
1) High efficiency and energy saving: Cosmetic freeze dryer adopts advanced freezing and drying technology, which can remove water efficiently and improve production efficiency while saving energy.
2) Preservation of active ingredients: In the freeze-drying process, the active ingredients in cosmetics are well preserved, ensuring product efficacy and quality.
3) Uniform drying: Cosmetic freeze dryers can realize a uniform drying effect, avoiding quality problems due to uneven drying of products.
4) Protect the color shape: In the freeze-drying process, it has been processed in a low temperature and vacuum environment to contain the oxidation reaction, and the moisture is physical migration can keep the molecular structure of the substance unchanged.
The lyophilization process of natural color powder mainly includes the following steps:
(1) Raw material preparation: natural ingredients and other formula ingredients are mixed proportionally to make the raw materials for color cosmetics powder.
2)Freezing: the raw materials are put into the cosmetic freeze dryer for freezing treatment so that the raw materials are rapidly frozen and form uniform crystals.
3) Drying: Under the vacuum environment, the frozen raw materials are subjected to drying treatment, so that the moisture is directly sublimated in the form of ice and water is removed.
4) Forming and packaging: The freeze-dried treated raw materials are molded and packaged to make natural makeup powder products.
Cosmetic freeze dryer has the following technical characteristics and development trends in the freeze-drying processing of natural color cosmetics powder:
(1) Intelligent: cosmetic freeze dryer gradually to intelligent, automation direction, improve production efficiency and product quality.
(2)Environmental protection and energy saving: cosmetic freeze dryers are paying more and more attention to environmental protection and energy saving in the process of designing and manufacturing to reduce the impact on the environment.
(3) multifunctional: the future of the cosmetic freeze dryer will be more multifunctional, able to adapt to different types of cosmetic production needs.
Cosmetic freeze dryers in the production of natural makeup powder can make the water in the cosmetics sublimation removed, the product will be transformed into solid or powder, so as to extend its shelf life, reduce bacterial growth, and maintain the active ingredients and color of the product. Freeze-drying technology has the advantages of simple operation, high production efficiency and stable product quality to meet the market demand.
