The odour neutralizer The weapon of citric acids, found naturally in fruits such as lemons, is neutralisation. They do so by balancing the pH value of odours to the pH of water (that's a neutral 7, just in case you were wondering). The perfect demonstration of how they work is in every bottle of Febreze Air Effects.

Actor Kieran Mulcare, known for his roles on TV shows including Jessica Jones and Gotham, stars in the ad as Dave, the smell-less man with parents who are more impressed with their son whose “bleep don't stink,” than their friends' whose son is a lawyer.

The active ingredient in several Febreze products is hydroxypropyl beta-cyclodextrin (HPβCD). The molecule traps and binds volatilized hydrocarbons within its structural ring, retaining malodorous molecules, which reduces their volatility and thus the perception of their scent.

Precautions. What are potential effects of citric acid on the body to be aware of? It's possible that it can be harmful if swallowed in large amounts. It may also cause skin irritation and allergic skin reactions, eye irritation, or potentially serious eye damage, nose and throat irritation.

Many air fresheners use a buffering system to neutralize bad scents. The next type of mechanism would be to react with the molecules, like with amine based odors (body odors) which can react with a perfume ingredient to form a large molecule. Lastly, oxidation is another mechanism to remove bad odors.

Air fresheners introduce fragrance into the air of interior spaces either as droplets which transition to vapor, or as the molecules of fragrance ingredients directly evaporating from a source. Fragrance diffuses into the air to mask other odors or to introduce a specific odor.
