Petroleum jellies and petrolatum: How to avoid confusion.

For 30 years, Aiglon has specialised in manufacturing petroleum jellies conforming to the requirements of the
French Codex Pharmacopeia, according to the reconstitution method
It's a good idea to recall the origins of petroleum jellies, and the influence of manufacturing methods on their physical and chemical characteristics.

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.]
It is this process in particular that determines the difference.
- Our petroleum jellies are of exceptional purity and stability
To manufacture our petroleum jellies according to the French Codex Pharmacopeia requirements we use highly refined pharmaceutical raw materials (mineral oil, microcrystalline wax and paraffin). Thus our petroleum jellies are of an incomparably superior purity and stability due to compliance with the PAH standards and the strictest carbonisable material. Unlike other pharmacopoeias, only the Codex petroleum jellies are authorised for oral use in pharmacy.
- We offer the largest range of petroleum jellies on the market, and make "made to measure" textures.
The flexibility of choice of raw materials allows us to control with the highest precision the essential qualities of the petroleum jelly:

  • The physical properties (drop melting point, viscosity, consistence, oil absorbance capacity)
  • Their textures and sensorial qualities (fibre length, spread-ability, unctuosity, brilliance, adherence etc.).
- Our petroleum jellies are not petrolatum.
According to the regulations of the International Nomenclature for Cosmetic Ingredients, there are two methods of manufacture for petroleum jellies:
  • 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.

We are the only GMP certified manufacturer of petroleum jellies.
The flexibility of our manufacturing has permitted us to rapidly set up new referential such as the GMP. In January 2008, AFSSAPS (the French Agency for the Safety of Health Products) delivered our certificate of conformity to GMP manufacturing, according to which, the operation of our facilities conforms to the principles of Good Manufacturing Processes for active ingredients.
Thanks to our know-how and our manufacturing flexibility, we develop "made to measure" petroleum jellies according to the needs of our customers and the final application.
