The various manufacturing processes
Petroleum jellies and petrolatum: How to avoid confusion.For 30 years, Aiglon has specialised in manufacturing petroleum jellies conforming to the requirements of the
1. The refining and rectification of a product distilled from crude petrol oil:
The refining methods vary according to the type of crude oil used and the general refinery process. With this type of procedure products of varying quality can be obtained, depending on the degree of purification - white, yellow, amber or brown products, pharmaceutical or technical grades. This process has limitations, and in any case, never meets the requirements of the French Codex Pharmacopeia.
2. The Fischer-Tropsch process::
Synthetic petroleum jelly is manufactured using synthetic hydrocarbons obtained by the hydrogenation of carbon monoxide.
3. The reconstitution process: :
This is a blend of paraffin, white mineral oil and microcrystalline wax. The reconstitution process produces the most pure petroleum jellies.[Dooms-Goossens A. et al.]
- The physical properties (drop melting point, viscosity, consistence, oil absorbance capacity)
- Their textures and sensorial qualities (fibre length, spread-ability, unctuosity, brilliance, adherence etc.).
- The product is manufactured from paraffin oil, wax and mineral paraffin, then the INCI name of the blend is composed of all the INCI names of the individual ingredients (Paraffinum Liquidum (and) Cera Microcristallina (and) Paraffin).
- The product is obtained by direct refining from crude oil and the INCI name is “petrolatum”.
Thus the INCI denomination of our petroleum jellies is « Paraffinum Liquidum (and) Cera Microcristallina (and) Paraffin”. Unlike petrolatum, these names, along with the CAS numbers of our petroleum jellies are not found on the CMR (Carcinogenic, Mutagenic and Reprotoxic) product list of the Cosmetic Directive end the Dangerous Substances Directive.
