Making concentrated fabric detergent
Richard Craven of Unilever demonstrates how to make a bottle of super-concentrated fabric detergent. Water is just one of many components in these concentrated products. Several different solvents are added for those ingredients that do not dissolve in water. The solvents also help to bind the ingredients to the water. Stabilisers, optical brighteners, alkalis to neutralise and clean, four different surfactants, acids, two dyes to obtain the turquoise colour, fragrance and a lot of stirring result in this compact cleaning product.
