ODOUR ELIMINATOR
THE main ingredient is cyclodextrin which traps the odour molecule so your nose can’t detect it, then blasts your receptors with a strong chemical fragrance instead.
Air fresheners never ‘freshen’ the air, they merely mask smells with synthetic fragrance, by interfering with your ability to smell or by coating your nasal passages with an oil ‘ film’ that temporarily blocks your sensors. Some contain a ‘nerve-deadening’ chemical that can paralyse the senses for a short time. As you regain it your brain gets acclimatised to the smell in the air so it’s less offensive than before.
ALTERNATIVE: A small dish of bicarbonate of soda can help to absorb offensive smells.
