Main reasons for using pure water and deionized water in daily cosmetics:
Cosmetics are daily necessities for girls. Water is a very important part of cosmetics. Some ions or impurities in the water can not only make the cream and lotion agglomerate, but also age the skin. Therefore, pure and sterile water is the base solution for skin care products. The quality of water seriously affects the quality and use of cosmetics. Safety. Therefore, it is crucial to remove various ions, particles and other impurities in the water to fully meet the requirements of ultrapure water. Of course, the conductivity of the effluent of the ultrapure water equipment needs to be able to be controlled at one to five microseconds per square centimeter, which is also the only choice for cosmetics manufacturers.
The requirements of most cosmetics for deionized water reach the level of ordinary pure water, which reduces the salt content to less than 1.0mg / L, and reduces the electrical conductivity to 1-10 μs / cm <20? ¡ã C, or the resistivity of 0.1-1MΩ ¡¤ cm>. Another requirement for cosmetic water is that it contains no or as few microorganisms as possible. Cosmetic hygiene standards stipulate that the total number of bacteria in general cosmetics should not be more than 1000 per ml or more or less than 1,000 per g; the total number of bacteria in cosmetics for eyes, lips, oral mucosa, and cosmetics for infants and children should not be greater than 500 per g. Pseudomonas aeruginosa and Staphylococcus aureus cannot be detected. Microorganisms can multiply in cosmetics, resulting in product spoilage, unpleasant odor, separation and agglomeration of the product, and harm to consumers. Any water-containing cosmetics may grow bacteria, and the most common source of bacteria may be water itself. Therefore, ultra-pure water, which is non-microbial contaminated production water (mainly raw material water), must be used as the basic water for cosmetics production.

According to the special requirements of cosmetics production water, water treatment processes can be roughly divided into four types:
The first type: deionized water obtained by using an anion exchange resin. Generally, after passing through, the conductivity of the effluent water can be reduced to less than 10us / cm, and then the mixed bed can reach 1us / cm or less. However, the water cost of this method is extremely high, and there are too many particulate impurities, which can not meet the ideal requirements. It has been adopted less frequently.
The second type: pretreatment (that is, sand carbon filter + precision filter) + reverse osmosis + mixed bed process. This method is currently the most used because the cost of reverse osmosis investment is not high, and 90% of the Ions in water, the remaining ions are removed by mixed bed exchange, so that the conductivity of the effluent can be about 5-10us / cm. This is currently the most popular method.
The third type: two-stage reverse osmosis is adopted, and the process is as follows.
Tap water → multimedia filter → activated carbon filter → softeners → intermediate water tank → low pressure pump → precision filter → primary reverse osmosis → PH adjustment → mixer → secondary reverse osmosis Pure water tank → pure water pump → microporous filter → water point;
The fourth type: pre-treatment uses reverse osmosis like the second method, except that the mixed bed used later is replaced by EDI continuous desalting membrane block, so that the resin is not regenerated by acid and alkali, but is regenerated by electricity. This completely makes the whole process pollution-free, and the treated water quality can reach more than 15M. However, this method has a large amount of initial investment and low operating costs. It is best to make appropriate investments according to the situation of each company. The process is as follows.
Raw water → multi-media filter → activated carbon filter → water softener → intermediate water tank → low pressure pump → PH value adjustment system → high-efficiency mixer → precision filter → high efficiency reverse osmosis → intermediate water tank → EDI water pump → EDI system → microporous Device → water point
