CERESIN WAX YELLOW - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| properties | microcrystalline wax is odorless, tasteless, and is a white amorphous solid wax. It is a kind of high boiling point long chain hydrocarbons obtained from the residue remaining after Petroleum fractionation by solvent extraction and chemical treatment, and its composition is mainly C31-70 of branched chain saturated hydrocarbons, A small amount of cyclic, branched chain hydrocarbons, melting point of 60-85 ° C, with a variety of mineral waxes, vegetable waxes and hot fat oil miscible. Such a wax is large in particle size, has ductility, is not weak at low temperature, and has a property of preventing separation and precipitation of oil when mixed with liquid oil. Melting point of 77-80 ℃ microcrystalline wax with more or less ductility, similar to the soft wax, melting point of 88-90 ℃ microcrystalline wax is hard, the appearance like Montan wax (Montan wax) |
| Use | microcrystalline wax can be used as nutrition enhancer, emulsifier, film coating agent and lubricant. Microcrystalline wax has good oil absorption performance, and a variety of solvents, waxes to form a stable, uniform paste, and emulsifying, can be used as shoe polish, car wax, polishing wax, floor wax, polish wax, pill, protective agents, candles, wax toys, dental materials and cosmetics and other processing aids. In addition, the use of the raw material in the wax paper formula can make the handwriting clear and the abrasion resistance is significantly improved. Microcrystalline wax has a wide range of uses, is the latest achievements of the 90's synthetic wax, can be used to replace the same type of imported solid wax, reducing the cost of about 50%. It has good adhesion and ductility, and is not fragile at low temperature. Adding liquid oil can prevent oil precipitation. In cosmetics, it can be used as an oil phase raw material for cold cream, lipstick, hair wax and the like. used for cosmetics, color pen, shoe polish, various polish wax, etc. |
