What is the white cream coroner's put under nose for decomposition smell?

The white cream that a coroner puts under their nose to mask the smell of decomposition is typically referred to as an "odor mask." These creams often contain substances like menthol or other aromatic compounds that help to neutralize or mask unpleasant odors. The use of odor masks is a common practice in forensic investigations to help professionals focus on their work without being overwhelmed by strong smells.
