The world of natural and synthetic waxes is filled with diversity. Waxes derived from hydrocarbons include paraffin and microcrystalline. While paraffin crystals are relatively large, microcrystalline, as its name suggests, is characterized by its tiny crystals. The smaller and finer crystalline structure of these waxes gives them greater flexibility compared to paraffin.

What’s more, microcrystalline waxes are generally denser, more viscous, darker and stickier than paraffin. They also have a higher molecular weight and a higher melting point.

Properties and applications of microcrystalline

The branched molecular structure of microcrystalline waxes gives them high viscosity and elasticity. Being highly cohesive, they have great adhesive power and resistance to water and vapor, and superb insulating and protective properties.

Microcrystalline is used in various applications, such as cosmetics, dentistry and industry, where it excels in laminating, coating and hardening materials. It is also used to protect wood, metals, stone and marble, on which it forms a delicate but resistant and flexible film.

Microcrystalline or paraffin?

Although in some cases, both paraffin and microcrystalline can be used, microcrystalline waxes have specific uses thanks to their greater flexibility and lower brittleness than paraffin. They also have a greater affinity with oils, which are trapped in their structure and cannot reach the surface. They are popular in the manufacture of dental supplies, as well as in shoe polishes, rubber bases and candles. In the cosmetics industry, crystalline waxes such as our Micro 721 Low Melting Point are essential in the manufacture of creams, lotions, stick products and depilatory waxes.
