There are several different perfumes available and each one has a different fragrance. They are made up of different ingredients. They can be made of natural resources, chemicals or a combination.
Most perfumes use a blend of aromas that are usually found in concentrated essential oils. There is a formula that goes with each perfume in order to reach that particular scent that you are trying to get.
Essential oils can be either natural or synthetic, which will affect the result of your fragrance. Natural ingredients cost a little more but it is worth it when you get the natural scent to combine to make the best fragrance.
To use synthetic essential oils will have an affect on the results of your fragrance. The fragrance may not last long, may not smell natural, or may cause an allergic reaction.
There are other ingredients that go into making a perfume, including Ethyl Alcohol. This type of alcohol will mix well with the essential oils.
There are two fixatives that may be used to allow the fragrance to last longer. Phtalates is a substance that is used as a fixative. Phtalates may cause an allergic reaction in some people as well as other harmful effects.
Glycerin is another common fixative to use in preserving the perfume. Glycerin can also cause an allergic reaction. These ingredients are important to maintain shelf life. If you are making your own perfume you may leave a fixative out to enjoy the natural scents without any harmful ingredients.
