How our long-lasting deodorants work
Chemicals produced by skin bacteria cause odor - so how can you stop them? Two natural methods: neutralize the odor-causing bacteria or bind up the odor molecules. Tom's aluminum-free Natural Long-Lasting Deodorant uses both ways to keep you smelling fresh, naturally. We use the odor-neutralization properties of zinc ricinoleate, sourced from castor beans, to trap and absorb bad smells. We also rely on the antimicrobial properties of the herbal ingredients coriander and lemongrass to neutralize odor-causing bacteria.
