odorless

This term describes a complete absence of olfactory detection. It is frequently used in scientific and industrial contexts to describe gases or chemicals that do not trigger a sensory response, which can be a safety hazard if a dangerous substance cannot be detected by smell. In consumer product marketing, the term suggests a neutral profile, indicating that a product has been stripped of natural scents or formulated without fragrances to prevent clashing with perfumes or causing allergic reactions.
