Have you ever noticed that a perfume you’ve had for a while doesn’t smell the same as when you first bought it? This change is often due to oxidation, a chemical process in which fragrance molecules react with oxygen over time, leading to a breakdown or alteration of the original scent. Ingredients like citrus oils or aldehydes are especially prone to oxidation, which can cause the fragrance to become sour, less vibrant, or even off-putting.
To combat this, perfume chemists often incorporate stabilizers or antioxidants into formulations to slow down the oxidation process and prolong the fragrance’s shelf life. However, proper storage also plays a key role in preserving the scent. Keeping the bottle out of direct sunlight, in a cool, dry place, and away from heat sources can significantly help prevent oxidation, ensuring that the fragrance maintains its original charm for as long as possible.
