Liquid detergent compositions comprising coacervate mixture of alkylcellulose and
carboxymethylcellulose and method for preparing them |
(57) Aqueous homogeneous liquid detergent compositions containing additive levels of alkylcellulose
and carboxymethylcellulose and a mixture of anionic and nonionic surface-active agents
are disclosed. The compositions have a pH in the neutral to mildly alkaline range.
The alkylcellulose/carboxymethyl- cellulose is present as a coacervate capable of
forming, in combination with the surfactants, a network of loosely associated droplets.
This network is tridimensional and provides means for stably and homogeneously suspending
detergent components/additives which otherwise could not be incorporated, particularly
ingredients which are substantially insoluble in the liquid compositions.
