Nose Guard® Masking Agent

The screening agent “Nose Guard” is produced by Chevron Phillips Chemical in the US, which can effectively cover up the unpleasant smell caused by a small amount of tetrahydrothiophene. It is mainly used to reduce a small amount of odors remaining on the valve body, container, barrel, and the ground or the surface of the workbench contaminated by natural gas or liquefied petroleum gas. The screening agent “Nose Guard” cannot remove odors, but it can cover them up with a pleasant slight citrus scent.
