At present, the disinfectants commonly used in swimming pools include: disinfectants, flocculants, algicides, and PH conditioners. There are many ways to sterilize swimming pools. Commonly there are ozone disinfection and ultraviolet disinfection, but mainly chlorine disinfection. One, commonly used chlorine agents are: 1. Bleaching powder. It is a mixture of sodium hypochlorite and calcium chloride calcium hydroxide. It is mostly white or off-white powder or granules. It has obvious chlorine odor, is very unstable, and has strong moisture absorption. It is easily decomposed by the action of moisture, light and heat. Can react with carbon dioxide in the air. The aqueous solution is alkaline, and the available chlorine component released from the aqueous solution is oxidized, sterilized and bleached. The disadvantage is that there is precipitation, there will be a layer of white floating on the water surface, there are irritation to the gastrointestinal mucosa, respiratory tract, skin and eyes. 2. Sodium hypochlorite. It is a colorless or light yellowish green liquid and is alkaline. When it encounters light in the heat, it is easy to explode and decompose in organic matter. It is a dangerous product of strong oxidants. Under photosynthesis, it rapidly decomposes into sodium chloride, sodium chlorate and oxygen. When the PH value is greater than 6.5, it is separated into a large number of sodium ions and hypochlorite. The hypochlorite killing effect is only 1% of hypochlorous acid, and the secondary chlorine is stabilized. The fact that the acid does not become hypochlorite is the key to improving the bactericidal action. 3. Sodium dichloroisocyanurate, also known as excellent chlorine net, is an organic chlorine preparation, mostly white powder. Soluble in water, storage stability, has gradually become a substitute for sodium hypochlorite. 4. Trichloroisocyanuric acid, alias strong chloric acid. White crystalline powder, or granules, flakes, not easily decomposed in a dry environment, long storage time, high content of hypochlorous acid in the hydrolysis process, strong bactericidal effect. 5. Dichlorohydantoin. White powder, slightly soluble in water, forms hypochlorous acid during dissolution and is a sustained-release disinfectant. 6. Dibromohydantoin. White or light yellow powder, slightly soluble in water, water capacity of 2.2 g/L at 20 degrees. The aqueous solution is acidic. The hypobromous acid generated in the dissolution process has strong oxidizing properties, and decomposes the enzymatic enzymes in microorganisms, which has a strong bactericidal effect. Second, flocculants: Currently used flocculants are mainly aluminum chloride, alum, aluminum sulfate and so on. 1. Polyaluminum chloride. Yellow or gray yellow, red-yellow powder, or granules, can be quickly dissolved in water, decompose aluminum hydroxide micelles, so that the impurities in the water attached to the cluster precipitation, so that water clarification. Flocculation in alkaline water is better. 2. Alum. White solid or granular, acidic, in the same principle as aluminum chloride in water. 3. Aluminum sulfate. White tablets or granules, in the same way as aluminum chloride in water. Third, the algaecide: There are many types of algicide, but the main use of copper sulfate. Copper sulphate, also known as malachite green, beautiful blue particles, basically odorless, usually 0.5-1 kilograms per kiloton of water, after the administration of the water will be milky white, gradually turn blue, but the number of uses should not be too much. Fourth, PH value modifier: 1. Hydrochloric acid. A colorless, or pale yellow liquid, with a pungent odor, acidic to neutralize the water's alkalinity. 2. Sodium carbonate, also known as soda ash, is a white powder that is alkaline to neutralize acidic water. 3. Sodium bicarbonate, also known as baking soda, color, nature with sodium carbonate.

How to Clean Eye Makeup Brushes:
1. Holding bristles face down, run bristles under warm water.
2. Gently squeeze out any excess water and makeup residue.
3. Apply a dime size amount of mild soap and olive oil into the palm of your hand.
4. Massage the bristles into your palm in a circular motion under running water until the water runs clear, being careful not to submerge the brush.
5. Gently squeeze out any excess water using a clean towel.
6. Let the bristles air dry in an open space.
Please note that if our makeup brushes smell like paint since they have been sealed in the bag for long time, don't worry! Just wash them in water with little shampoo and wait them dry, the smell will disappear!
