However, you could consider these options depending on the context:
* Perspirant: This focuses on reducing sweat, which is a common cause of body odor.
* Antiperspirant: This directly prevents sweat, which is a more powerful approach than simply masking odor.
* Odor enhancer: This would be the opposite in the sense that it intensifies body odor, though this is not a common concept.
* Something that causes body odor: This could be anything that makes you sweat more (like spicy food) or something that creates a strong odor (like garlic).
Ultimately, the best "antonym" for deodorant depends on the specific context you're using it in.
