ABSTRACT
A project was carried out to produce high quality liquid air refreshner for domestic uses. The project was carried out using the following apparatus. Beakers (250ML), one conical flask, hydrometer, thermometer, two – 5ml of measuring cylinders, one reactor (plastic reactor), stirrer, weighing balance.
The chemicals used in the production of liquid air refreshner are: Amyl alcohol, ethanol, acetone, benzyl acetate, vitus vinyera (grape root extract), citranol (lemon grass extract), sodium benzoate, sodium lauryl sulphate, naphthalene, phenol and water as solvent.
Different sequence of addition of the chemicals was investigated and two correct sequence development. They are: Filtrate + Amyl Alcohol + Benzyl acetate + Acetone + Water + Sodium Benzoate + SLS + Naphthalene + Phenol. And Filtrate + Amyl alcohol + Water + Sodium Benzoate + Benzyl acetate + Phenol + Acetone + SLS + Naphthalene.
The effectiveness of the liquid air refreshner were tested using micro-organisms. From the result obtained, formation B gave phenol coefficient of 7.86 which was slightly above the standard phenol coefficient of odour control which is 7.74. Formulation A gave exactly 7.14 as the phenol coefficient which conforms with the standard phenol coefficient of odour control material costing as well as economics costing was equally carried out.
