  • Microcrystalline paraffin, method for producing microcrystalline paraffins, and use of the microcrystalline paraffins
    Publication number: 20060118462
    Abstract: Microcrystalline paraffin having a consistency in a rage of paste-like to solid, prepared by catalytic hydroisomerization of FT paraffins having a carbon chain length distribution in a range of 20 to 105 at temperatures above 200° C., and being free of aromatic compounds, heterocyclic compounds, and naphthenes.

  • Microcrystalline paraffin-
    Publication number: 20040192979
    Abstract: The invention relates to a novel and completely synthetic microcrystalline paraffin, said paraffin being obtained in a simple manner and with a high yield by the catalytic hydromerisation of paraffin FT comprising 20 to 105 carbon atoms. Said paraffins can be pasty to solid at room temperature and have a higher percentage of iso-paraffins than n-paraffins. Since they do not contain aromatic compounds they are particularly suitable for use in the pharmaceutical, cosmetic and food industries.

  • Kerze (candle)
    Patent number: 6096102
    Abstract: A candle comprising candle base materials of a variety of kinds, on the one hand of a candle base material of a first kind which consists in part of white oil and of copolymer, synthetic paraffin being further contained as a constituent, in particular of chain length C18 to C20, and on the other hand of a candle base material of a second kind consisting of conventional paraffin derived from crude paraffins. The different candle base materials are arranged one over the other in a layered manner.
