What Is Microcrystalline Wax?
Microcrystalline wax, white amorphous amorphous solid wax, mainly branched saturated hydrocarbons of C31-70, containing a small amount of cyclic and linear hydrocarbons, odorless and tasteless. Insoluble in ethanol, slightly soluble in hot ethanol, soluble in benzene, chloroform, ether, etc .; it can be miscible with various mineral waxes, vegetable waxes and hot fatty oils. It is mainly made by using the refining method after taking the residue of petroleum fractionation as raw material. Used as glazing agent for paste products, rust inhibitor, carbon paper, candles, packaging impregnation and fruit coating; it is also used in cosmetics, color pens, shoe polish, various glazing waxes, etc. [1]

Chemical composition of microcrystalline wax
- Mainly branched saturated hydrocarbons of C31-70, containing a small amount of cyclic and linear hydrocarbons, the ash content is below 0.05%, and its heavy metals lead and arsenic content are below 2 × 10 -6 This kind of wax has large viscosity, has ductility, is not fragile at low temperature, and has the characteristics of preventing separation and precipitation of oil when mixed with liquid oil. Microcrystalline wax with a melting point of 77-80 ° C is somewhat ductile, similar to soft wax. Microcrystalline wax with a melting point of 88-90 ° C is hard and looks like montan wax. [1]
Microcrystalline wax synthesis method
- Refining method is mainly used. The residue after petroleum fractionation is used as a raw material, and a fraction of branched saturated hydrocarbons above C31 is extracted by distillation, and then deoiled and decolorized to obtain the fraction. [1]
Main uses of microcrystalline wax
- It is used as glazing agent for paste products, rusting agent, carbon paper, candle, packaging impregnation and fruit coating; it is also used for cosmetics, color pens, shoe polish, various glazing waxes, etc. [3]
