Concentrated cleaner in water-dissolvable pouch
Concentrated liquid cleaning fluid compositions for hard surface cleaning which are particularly suited for storage and dispensing from water-dissolvable plastic pouches. In use the pouches are placed in water whereupon the plastic pouch dissolves allowing the concentrated composition to become diluted in the water to provide a cleaner. The concentrated cleaning composition has good stability and does not affect the plastic or rate of dissolution of the pouch, and allows use of a variety of colorants and fragrances with a base product formulation. The formulation includes a linear alkyl benzene sulfonic acid (LABSA), a nonionic ethoxylated alcohol surfactant, and an alkanol amine or alkyl amine capable of reacting with the LABSA so that the sulfonic group is added to the amine.
