Abstract
Slurries of pentaerythritol in a liquid oil in which pentaerythritol is substantially insoluble are disclosed. The slurries can contain up to 70 percent by weight or more of solid pentaerythritol. Suitable oils include propylene glycol, ethylene glycol, vegetable oils, glycerin and tall oil fatty acid. The slurries are stable and flowable allowing for shipment in bulk.
