Many people know that the chemical cosmetics industry production is the use of pure water equipment to produce water, so why do cosmetics production to use pure water or deionized water? Water is the most widely used in the production of cosmetics, the cheapest and most abundant raw materials, water has a good solubility, but also an important emollient material. Most cosmetics such as various creams and lotions in shampoo baths contain a lot of water. Water plays an important role in these cosmetics.

Many people know that the production of chemical cosmetics industry uses pure water equipment to produce water, so why should pure water or deionized water be used in cosmetics production?
Water is the most widely used in the production of cosmetics, the cheapest and most abundant raw materials, water has a good solubility, but also an important emollient material. Most cosmetics such as various creams and lotions in shampoo baths contain a lot of water. Water plays an important role in these cosmetics. The quality of water used in cosmetics production directly affects the quality of cosmetics production process and final products.
In order to meet the requirements of high stability and good usability of cosmetics, there are two requirements for cosmetics production water, including the concentration of inorganic ions and microbial contamination. Most cosmetics require deionized water to reach the level of general pure water, so that the salt content is reduced to below 1.0mg/L, the conductivity is reduced to 1~10 μs/cm <20 ℃, or the resistivity is 0.1~1 mΩ · cm> 〉. Another requirement for cosmetic water is that it contains no or as little microorganisms as possible. The hygiene standard for cosmetics stipulates that the total number of bacteria in general cosmetics shall not be more than 1000/ml or more than 1000/g; The total number of bacteria in cosmetics for eye, lip, oral mucosa and cosmetics for infants and children shall not be more than 500/g, while Pseudomonas aeruginosa and Staphylococcus aureus in fecal coliform shall not be detected. Microorganisms will multiply in cosmetics, resulting in product corruption, unpleasant odor, product separation and agglomeration, and harm to consumers. Any cosmetic product containing water can grow bacteria, and the most common source of bacteria is probably water itself, so modern cosmetic factories must use water that is free from microbial contamination.
