PRODUCTION OF LIQUID AND VAPORIZED PERFUME. A RESEARCH PROJECT MATERIAL ON CHEMICAL ENGINEERING
ABSTRACT
This research project was carried out principally for the production of liquid and vapourized perfumes from local raw materials. The local raw material were subjected to various processing conditions in order to obtain purified perfume. The methods generally used in this work include expression steam distillation and solvent extraction.
During the production of vapourized and liquid perfume the modern solvent for blending and holding perfume materials is highly refined ethanol mixed with more or less water according to the solubilities of the oils employed. This solvent with its volatile nature helps to project the scent it carries, and it is fairly inert to the solute and is not too irritating to the human skin.
The slight natural odour of the alcohol is remove by deodorizing of the alcohol. This is accomplished by adding a small amount of gum benzoic or other resinous fixatives to the alcohol and allowing it to mature for a week or two. The result is an almost odorless alcohol, the natural rawness having been neutralized by the resins. Other vehicles added to this includes benzene which is a solubilizer and methanol in their required proportions.
For vaporized perfumes , it has light quantity benzene while the liquid perfume has little or no of benzene and it contains more of the fragrance than the vapourized perfume.
However, it can be concluded that liquid and vapourized perfumes can be produced using local raw materials.
CHAPTER ONE
INTRODUCTION
The word perfumes take its name form the latin word perfumery (to fill with smoke) since in its original form, it was incense burner in Egyptian temple early it was found in a mixture of finely ground spices help together by Mgrrh or storax.
It occur in certain spices and flowers were steeped in fat or oil, the fat or oil would retain a portion of the odoriferous principle which can be blended by a constitutes like vehicle a solvent and fixture.
It also occur in some leaves, seals fruits and grasses. It first production data back to the 6th century BC when God gave Moses an instruction to make an acter of twin incense and Aaron shall burn there on sweet morning (ref Exodus 30:23)
