[42] \n Appendix II: Alcohol quantity in the perfumes \n Perfume oils are often diluted with a solvent, though this is not always the case, and its necessity is disputed. By far the most common solvent for perfume oil dilution is ethanol or a mixture of ethanol and water. Perfume has a mixture of about 10\u201320% perfume oils mixed with alcohol (acting as a diffusing agent delivering the fragrant odour) and a trace of water.

Colognes have about 3\u20135% perfume oil mixed with 80\u201390% alcohol with about 5\u201315% water in the mix. [43] \n Perfumer’s alcohol is often compared to other solvents commonly used in perfumery, such as ethanol, isopropyl alcohol, and carrier oils.

While each solvent has its unique characteristics and applications, perfumer’s alcohol is favoured for its ability to provide a neutral base with minimal odour interference, making it ideal for preserving the integrity of fragrance compositions.
