Abstract
A composition for odor control includes (A) from 85 wt % to 99.5 wt % of an olefin-based compound and (B) from 15 wt % to 0.5 wt % of an odor suppressant. The odor suppressant includes a blend of (i) an ionomer, (ii) particles of zinc oxide, and (iii) particles of copper oxide. The composition has a methyl mercaptan odor suppression value of greater than 45% as measured in accordance with ASTM D5504-12.
