Primol 352
Medicinal grade White Oil
Product Description
Primol 352 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 352 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 352 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 352 is recommended as a food packaging-grade plasticizer in general purpose and high impact polystyrene. Primol 352 is recommended for use as an external lubricant for non-plasticized PVC. Primol 352 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 352 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 352 is also recommended for Hot-Melt Adhesives formulations used in sanitary products.
Cosmetics and Pharmaceuticals
Primol 352 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.
Further detailed information is available in our bulletin White oils for Cosmetics.
(*) User must check compliance with applicable regulations. As an example, at the date of this publication, Primol 352 can be used as a food additive in USA subject to applicable FDA regulations, while it cannot be used as a direct food additive in European Union Member States
