The below picture will show you the certain process obviously.

1.Collection of raw material and ingredients

Before the manufacturing process begins,the initial ingredients must be brought to the manufacturing center. There are three main categories of ingredients:

Plant substances are harvested from around the world, often hand-picked for their fragrance.

Animal products are obtained by extracting the fatty substances directly from the animal.

Aromatic chemicals used in synthetic perfumes are created in the laboratory by perfume chemists.

2. Extraction the oil from ingredients

Oils are extracted from plant substances by several methods: steam distillation, solvent extraction, enfleurage, maceration, and expression.

3.Blending different oils as scents with Alcohol

Once the perfume oils are collected, they are ready to be blended together according to a formula determined by a master/nose in the field. It may take as many as 800 different ingredients and several years to develop a special formula for a scent.

After the scent has been created, it is mixed with alcohol. The amount of alcohol in a scent can vary greatly. Most full perfumes are made of about 10-20% perfume oils dissolved in alcohol and a trace of water. Colognes contain approximately 3-5% oil diluted in 80-90% alcohol, with water making up about 10%. Toilet water has the least amount—2% oil in 60-80% alcohol and 20% water.

4.Aging

Fine perfume is often aged for several months or even years after it is blended and mixed. Following this, a "nose" will once again test the perfume to ensure that the correct scent has been achieved.

Each essential oil and perfume has three basic notes:

Top notes have tangy or citrus-like smells;

Middle notes (aromatic flowers like rose and jasmine) provide body.

Base notes (woody fragrances) provide an enduring fragrance. More "notes," of various smells, may be further blended.
