  We like to focus on the ingredients of beauty products. But we prefer to touch the product and explore whether it really works. Alpha hydroxy acid is also known as AHA. It includes glycolic acid production , lactic acid and citric acid. These products do not meet the needs.   Now we analyze the most popular ingredient in the world - glycolic acid.   Glycolic acid is a naturally occurring substance that is added to skin care products. It is good for the skin and restores skin elasticity and moisturization. The original state of glycolic acid is a powder composed of colorless crystals. It is tasteless. Let's first understand its benefits and its related products.   The Benefits of Glycolic Acid Glycolic acid is very effective for skin treatment because of its high purity. The premise is safe and correct use. Many skin care products contain glycolic acid. Sensitive muscles can also be used. Glycolic acid is non-irritating and it can be used in skin care. Add more glyc...

  Brief Introduction of Expandable Microsphere The color of the expandable microspheres is white. Its average particle size is 10-30 μm. Its average density is about 1100 kg / m 3 . It has a thermoplastic shell comprising a low boiling liquid hydrocarbon. When the thermoplastic shell is softened at elevated temperatures, the increased pressure of the hydrocarbon will cause the microspheres to expand 40 to 100 times. When the internal pressure of the microsphere, the shell tension and the external pressure reach equilibrium, the microspheres no longer expand. Expandable microspheres have become the world's lightest application because the density of expanded microspheres is less than 30 kg / m3 (0.03 g / cm3).   Characteristics of Expandable Microsphere The first feature is cost savings. In thermoplastic materials such as PR, PP, PVC, PET, TPR, TPU, TPV, PA and paper/paperboard, expandable microspheres can be used as lightweight fillers and blowing agents. Expandable microspher...

  P olyether P olyol U ses Polyether polyol is abbreviated as polyether. It is an oligomer whose main chain contains ether bond (—R—O—R—) and the terminal group or side group contains more than 2 hydroxyl groups (—OH). It is prepared by addition polymerization of an initiator (a compound containing an active hydrogen group) with ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO), etc. in the presence of a catalyst. The largest polyether producers are all common polyether polyols. Polyether polyols are produced with glycerol (glycerol) as the initiator and epoxide, by changing the PO and EO addition methods (mixed addition or separate addition), addition ratio, addition order and other conditions.   The main purpose 1. Detergent or defoamer L61, L64, F68 are used to prepare low-foam, high detergency synthetic detergent; L61 and L81 are used as defoamers in the papermaking or fermentation industry; F68 is used as an antifoaming agent in the blood circulation of artif...

  Application Of Sodium Lauryl Ether Sulfate In Shampoo   The main surfactant used in shampoos is to impart a shampoo cleansing action through the washing process. There are many types of such surfactants, but mainly anionic surfactants. Nowadays, the amount of ammonium laureth sulfate (AESA) and (K12A) is also very large. The ammonium salt has a high foaming rate and is less irritating than the sodium salt. Some large brands use ammonium salt as the main surfactant. S odium lauryl ether sulfate  can be used in products for skin and sodium sulphate can be used in soap making.   Currently, the most commonly used shampoo main surfactants are lauryl ether sulfates (abbreviated as AES or SLES) and lauryl sulfates (AS or SLS), sometimes a mixture of the two. China generally uses sodium laureth polyoxyethylene ether sulfate and ammonium laureth polyoxyethylene ether sulfate, but mainly sodium salt.   The advantages of sodium salt 1. The sodium salt is less dependent o...
