Table 1. Relative efficacies of different absorbents for the uptake and removal of antifreeze and motor oil, which are common spills in garages, car dealers, etc. All data are standardized to reflect 17 in x 17 inch pad and the value followed by + is the standard deviation from an average of three replicates.

OilMaster - Oil Absorbent Pads. The eco-friendly, easy way to clean up oil spills and other hydrocarbon based liquid spills. Absorbs 16X times their weight in oil or other hydrocarbon based liquid. Perfect for quick response to oil spills, hydraulic fluid spills, gasoline and diesel spills, paint spills and more!
This information demonstrates that our products are very effective. The comparison products are a standard universal pad and a polypropylene pad. Both are about 1/8 in. thick.
The efficacy data is for oil and anti-freeze, which are the two most common spills in garages. The value for removal is determined by allowing a pad to completely saturate in the test material, and then removing and weighing immediately to determine the total amount of oil or anti-freeze that can be removed. This value is similar to those we find in product descriptions of competitive products.
It also is important to determine how much of the oil or antifreeze can be retained by the pads. Obviously, it doesn’t help much if the pads are used to absorb a spill but then drip and leak thereafter excessively. In the tests, they are allowed to drain for two hours and their retention data are in the second column. It also is important to determine how fast the pads work, this is provided in the last column.
Our standard OilMaster pads are better than the comparative universal pad in essentially every category. The level of oil and antifreeze removal is higher and the level of retention is much better. For antifreeze, the universal pad retains only 50% of the total that it removes. This universal pad is composed of numerous thin sheets and much of the removed product is simply held between the sheets and not actually absorbed by the material. The OilMaster pad is almost equal to the standard polypropylene pad in oil removal and, of the oil that it takes up, it is somewhat better in retention. The water repellent OilMaster pad is a little more effective than the standard one in oil removal, but it does not, of course, take up antifreeze, as is the case with the polypropylene pad. This water repellent pad floats on water and its primary use will be in spills on waterways, where it will directly compete with polypropylene.
These comparisons strongly indicate that both our standard and water repellent OilMaster pads are effective and as such, we have developed a comprehensive sorbent product line: the granular OilMaster 7X, a standard general purpose OilMaster pad and a water repellent OilMaster pad.
