Are there any non-food uses of sugar?

Sugar is involved in the fermentation process to produce alcohol for human consumption and for industrial alcohol to produce industrial chemicals. It is used as a retarding agent for cement and glues and as a raw material in the manufacture of rigid polyurethane foams. Sucrose is used in the textile industry for sizing and finishing fabrics. Sucrose fatty acid esters are biodegradable surfactants for use in foods, cosmetics and detergents. These esters are also used to preserve fruit and vegetables.
