Synopsis This article is an introduction and general discussion regarding the use of F isher‐ T ropsch wax in petroleum jelly applications. Traditionally, petroleum jelly is prepared from a blend of microwax, paraffin wax and mineral oil that are all derived from crude oil. S asol W ax has successfully prepared a petroleum jelly based on predominantly to fully synthetic F isher‐ T ropsch wax. S asol W ax was awarded a patent P 53898 ZP 00‐29 N ovember 11 for a predominantly to fully synthetic petroleum jelly based on F isher‐ T ropsch wax blends. The benefits of F isher‐ T ropsch wax discussed in this article include the absence of aromatic compounds and polycyclic aromatic compounds in F isher‐ T ropsch wax as well as the sustainable production that is possible with F isher‐ T ropsch wax, as opposed to paraffin wax that may be affected by the closure of group I B ase O il plants. This article will be the first in a series of articles from the same authors, and follow‐up articles will include solid‐state nuclear magnetic resonance and crystallization studies to determine the influence of predominantly synthetic waxes on petroleum jelly network structures compared with more traditional mineral oil‐derived petroleum jellies, final product performance and stability of synthetic petroleum jelly used in, for example, personal care lotions or creams. The influence of oxygenated compounds and product safety and rheological properties (including primary skin feel upon application and secondary skin feel after application) of synthetic petroleum jellies compared with traditional mineral oil‐derived petroleum jellies are discussed.
