One of the most demanding areas of perfumery. Here, a pleasing fragrance is simply not enough. Often, it must also remain stable in the most challenging of conditions as in a bleach-based cleaning product. Sometimes, the rate of release needs to be fast, such as in an aerosol air freshener. At other times, extremely slow â€” such as in scented candles or a fabric softener which gently releases its fragrance over days without being overpowering. Occasionally, the fragrance must do more than simply mask malodours - it must actively reduce them. Our fragrances do complete justice to these tasks.
