Applications of the perfume involves applying a fragrance oil or essence to a consumer product. Solubility of the fragrance in the product base is a major consideration. The wide variety of products like : aqueous fabric conditioner, or volatile silicone-fluid based antiperspirant or hair-dressing based mineral oil, could render the product immiscible, forming either droplets or a complete separation of layers. Dosing liquid fragrance in powder products can also affect a powder's flow characteristics or cause lumping.

    After successfully dosing the product with the perfume, tests have to be performed to ensure that the perfume remains evenly dispersed within the product and does not cause its physical and chemical characteristics to change significantly over time or over different climates.
