PRP is a loose dry powder composed of hollow microspheres of beeswax, soy wax, and other natural waxes. PRP microspheres range in size from 10 microns to 150 microns. [ 4 ] The waxes that comprise PRP are natural hydrocarbons making them oleophilic (having a strong affinity for oils rather than water) and hydrophobic . [ 5 ]
Sorbents collect specific liquids or gases depending on the composition of the material being used in the sorbent. Some of the most common sorbents used to clean oil spills are made from materials that are both oleophilic and hydrophobic, have high surface area through structural designs that include pores and capillaries, and draw in liquid through capillary action.

Superabsorbent polymer powder. A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers [1] that can absorb and retain extremely large amounts of a liquid relative to its own mass.
Fuller's earth is a term for various clays used as an absorbent, filter, or bleaching agent. Products labeled fuller's earth typically consist of palygorskite (also known as attapulgite) or bentonite.

According to Dr. Ian Smith, a gasoline spill on a disposable tarp can be absorbed using cat litter. He recommends leaving the cat litter down for at least 48 hours. If you don't have cat litter ...
Super-absorbent polymers (SAP) similar to sodium polyacrylate were developed in the 1960s by the U.S. Department of Agriculture. [3] Before the development of these substances, the best water absorbing materials were cellulosic or fiber-based like tissue paper, sponge, cotton, or fluff pulp.
