Primol N 542

Medicinal grade White Oil

Product Description

Primol N 542 is a purified mixture of liquid saturated hydrocarbons. It is a colourless, transparent oily liquid and is essentially odourless and tasteless. It is obtained from petroleum through several refining stages, including an ultimate purification by catalytic hydrogenation. Primol N 542 contains 5 ppm food-grade alpha-tocopherol (vitamin E) as an oxidation inhibitor.

Primol N 542 is manufactured to exceed the purity requirements of the Pharmacopoeias Due to its superior chemical inertness, it demonstrates better colour and oxidative stability than most mineral and vegetable oils, when stored and used under controlled conditions.

ExxonMobil White Oils are produced and controlled according to the ExxonMobil Product Quality Management System, EN ISO 9000 or equivalent standard.

 

Applications

Primol N 542 can be used in a variety of food-related, cosmetic and pharmaceutical applications subject to the applicable laws and regulations in each country (*).

Thermoplastics

Primol N 542 is recommended as a food packaging-grade plasticizer in Polystyrene. It offers an outstandingly low volatility but due to its high molecular weight, it is best used in grades at relatively low oil content, in order to maintain transparency for General Purpose PS grades.

Primol N 542 is recommended for use as an external lubricant for non-plasticized PVC.

Elastomers and Adhesives

Primol N 542 is used for producing food-contact or medical rubber articles, such as EPDM or butyl rubber. Because of its extremely low volatility, it is particularly well suited for the extension of Thermoplastic Elastomers when low fogging properties are required.

Primol N 542 is also recommended for Hot-Melt Adhesives formulations used in sanitary products.

(*) User must check compliance with applicable regulations. As an example, at the date of this publication, Primol N 542 is not considered as medicinal grade white oil in Japan. It cannot be used in Pharmaceutical applications in this country unless additional regulatory requirements are met.     

Properties and Specifications

Primol N 542 meets the requirements of the following specifications:

(*): Primol N 542 does not comply with theLiquid Paraffin definition of the European Pharmacopoeia due to the addition of an oxidation inhibitor and because of its high visocsity.
