The traditional jar of black KIWI brand shoe polish contains a variety of substances: Heavy Naptha, 3', 6'-Bis-(Diethylamino) Flouran, 4-Diethylaminoazobenzene, Carnauba Wax, Stoddard Solvent, 1, 2,3-4 Trimethyl Benzene and Solvent Black 7. These materials are used to shine and protect leather goods.
Naptha is essentially a material that dissolves wax and enables it to be spread into a layer. The second ingredient listed, Flouran, is a type of dye. Diethylaminoazaobenzene is actually another type of dye that enables the production of intense colors. Carnauba wax, which is a more common ingredient, is used for waterproofing and helps to shine leather. Stoddard solvent also dissolves wax, while producing a very strong odor; Trimethyl Benzene is simply a by-product of this solvent. Finally, Solvent Black 7 is a dye that works at the cellular level.
