- the liquid, aqueous detergents contain 10 to 50% by weight of surfactants. You can contain an anionic or nonionic surfactant in the amount specified. However, it is also possible to use mixtures of anionic and nonionic surfactants. In such a case, the content of anionic surfactants in the liquid detergent is chosen from 10 to 30% by weight and the content of nonionic surfactants in the liquid detergent from 5 to 20% by weight, based on the total detergent formulation.
