WAXREX ™1281

ExxonMobil specialties , Canada

Product Description

Waxrex 1281 is a lower-range melting point semi-refined paraffin wax. It is derived from petroleum via a carefully controlled refining process to provide low color and controlled oil content. Waxrex 1281 meets the requirements for most industrial wax applications and Food and Drug Administration (FDA) standards for indirect food contact substances. Waxrex 1281 is a translucent crystalline material in the solid state and is water-white in color and low in viscosity when molten. It is composed mainly of normal, straight chain paraffin hydrocarbons that impart properties of water repellency.

Waxrex 1281 contains an oxidation inhibitor to enhance the natural resistance to oxidation.

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



Waxrex 1281 is primarily used as a component in the manufacture of candles subject to applicable laws and regulations in each jurisdiction*.

* User must check compliance with applicable regulations.
