Introduction
During 1000 B.C. in Mesopotamia, perfumery started playing an important role in different cultures and Tapputi, a known perfumer, was named the world’s first chemist. Perfumes were first used by the Egyptians for their religious ceremonies and later on used by wealthy personals to cover up smell of illnesses and as home fragrances.[1] Perfume comes from the Latin word “per” means through and “fumum” means smoke. During ancient times, perfumes are made from oils extracted from plants then burnt to scent the air.[2]

There are a lot of method

Other ways are expressed oils method for extracting oils from citrus fruits, enfleurage method for flowers, carbon dioxide extraction and phytonic process. Perfumes come in two forms based on their carrier namely: alcohol-based and oil-based. Carrier is the solvent used to dissolve the essential oils and carries the fragrance to our skin. Perfumes may also be classified according to the concentration of the essential oil. The more concentrated the essential oil, the longer the scent will last.[1] Below are the

Preparation of Eau de Toilette
In a 50-mL beaker, 3.0 mL of essential oil and 1.0 mL of fixative were mixed thoroughly. Then, 30.0 mL of triple distilled ethyl alcohol and 3.0 mL of distilled water were poured and mixed in the solution. The solution was stirred well and transferred into an atomizer. The prepared solution was stored for ageing for atleast 2 days. Afterwards, the percent of essential oil was determined.

Results and Discussion
The eau de toilette was done by mixing 3.0 mL essential oil and 1.0 mL fixative. Essential oil is the main ingredient which highly contributes to the scent of the perfume while fixative promotes its lasting effect by equalizing the perfume with the vapor pressure which will decrease its volatility. There are two types of fixative: natural and synthetic. Natural fixatives are usually resinoids and animal products while the synthetic fixatives can be chemicals with low volatility.[4] Afterwards, a large volume of triple distilled water was mixed to the solution. Triple distilled alcohol was used to avoid impurities which might affect the clarity of the eau de toilette.[5] Then, distilled water was poured into the solution. The solution was transferred to an atomizer and stored for 2 days for ageing. The ageing process helps bind the oil and alcohol together and usually smells lighter than
