Shoes polish production using the concept of chemical engineering process

Abstract

The popularity of shoe polishes started in mid-19th century and continued
throughout the 20th century leading to the rise of leather and synthetic shoe
manufacture. Substances like wax and tallow have been used as starting
materials for shoe polish hundreds of years ago, and these material
combinations are still in use today. Modern shoe polish production
employed a mixture of natural and synthetic materials that include wax,
lanolin, naphtha, ethylene glycol; turpentine, oil soluble dyes, and gum
Arabic were processed by straight forward chemical engineering method.
Flow charts are drawn to show typical industrial process; the material
balances are conducted through accumulation in which 70% and 30% feed
solutions of MA and MB streams contained 2kg and 1kg respectively were
mixed then fed into the heater unit at 100°C. The batch process showed
that the law of mass conservation exists where input is equal to output.
Laboratory determination of product quality was carried out, the shoe
polish showed density ≤ 0.99kg/L, specific gravity of 1.01, flash point
>93°C using setaflash closed cup, 84-89% of kiwi liquid wax shoe polish
was volatile, shoe polish was dispersible in water. Appearance: liquid wax
shoe polish can be neutral, black, brown, blue, or red.
