Microcrystalline Wax :
Microcrystalline wax is a type of petroleum-based wax derived from the petroleum refining process. Specifically, by de-oiling petrolatum or petroleum jelly. Microcrystalline differs from paraffin wax in that the crystal structure is more branched and the carbon chain is longer. The finer crystal structure makes microcrystalline wax more flexible than paraffin wax as well. This material has numerous properties that have made it popular to use in cosmetics and beauty products. Microcrystalline wax acts as a water-repelling agent for waterproof mascara, and as a structure formation agent for eyeliner pencils.
