Primol N 382

ExxonMobil specialties , New Zealand

Medicinal grade White Oil

Product Description

Primol N 382 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 382 contains 5 ppm food-grade alpha-tocopherol (vitamin E) as an oxidation inhibitor.

Primol N 382 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.



Primol N 382 can be used in a variety of food-related, cosmetic and pharmaceutical applications subject to the applicable laws and regulations in each country (*).



Primol N 382 is recommended as a food packaging-grade plasticizer in Polystyrene. It combines outstandingly low volatility and excellent compatibility with Polystyrene for optimal performance in General Purpose and High Impact PS grades.

Primol N 382 is recommended for use as an external lubricant for non-plasticized PVC.

Primol N 382 is an inert and protective catalyst carrier for polypropylene processes. It can also serve as a pigment powder dispersant in master batch compounding.


Elastomers and Adhesives

Primol N 382 is used for producing food-contact or medical rubber articles, such as EPDM or butyl rubber. It is particularly well suited for the extension of Thermoplastic Elastomers (TPE), such as SBS, SEBS or SEPS. Primol N 382 is also recommended for Hot-Melt Adhesives formulations used in sanitary products.

Cosmetics and Pharmaceuticals

Primol N 382 has many well-established applications in the pharmaceutical industry, like laxative jellies and ointments, and is also recommended as a component for many cosmetic products, such as creams and body lotions.
