What is boot polish?
Lanolin, a hydrophilic grease from wool-bearing animals such as sheep or goats, acts as both a waterproofing wax and a bonding agent, giving the shoe polish its greasy feel and texture. It also prevents the naphtha from evaporating until the polish has been spread and buffed into a thin film on the leather surface. An essential ingredient in shoe polish is a thickener; without this, the polish would be too runny, making it difficult to use. Gum arabic, a substance from two sub-Saharan species of the acacia tree, is commonly used to increase the viscosity of the product.
