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.
