Is Spill Magic an absorbent or an adsorbent?

Spill Magic is an absorbent. An absorbent acts like a sponge and actually takes on the nature of the absorbed material. But unlike a sponge, when used properly Spill Magic will not release the material – even when under pressure, as in a landfill. An adsorbent (clay) is like a rock, and when liquids coat the surface of the adsorbent, the surface will not absorb any more material. When landfilled the absorbed material can be released, but may also simply fall off the adsorbent into the landfill.
