Description

- 1 - C 679 (R) LIGHT ~UTY LIQUID DETERGENT COMPOSITION
-As liquid dishwashing detergent formulations become increasingly popular with the consumer, the performance of such detergent compositions for cleaning kitchen utensils, such as glasses, dishes and other apparatus, becomes more important. Many performance characteristics are associated with this type of detergent formulation, among which are foamability, detergency, soil suspending abilit~ and mildness. In addition, the consumer ; has become concerned with both the final appearance of the objects that are washed and the ease with which washing, rinsing and the - 10 drying of the kitchen utensils can be accomplished.
Spotting may be referred to as resulting from the break up of a once continuous liquid film followed by the isolation of liquid patches that become stranded on the solid surface. Upon the drying of these isolated liquid patches, spots will form from the solid residue that was dissolved or suspended in the liquid. One of the disadvantages associated with liquid dishwashing detergent compositions, therefore, is the need to dry the washed objects or apparatus with a towel so that spot and film formation from the minerals in the rinse water can be avoided or minimized to a large extent. Moreover, because of the amount of water that remains undrained on the glassware and plates and kitchen utensils, etc.7 the towel drying process tends to become time-consuming and an additional burden to the consumer, thereby leaving it more desirable to let the washed utensils or apparatus drain and dry by themselves under ambient conditions.

- 2 - ~ 67 Various attempts have been made to minimize the effect of the water hardness residue and film-forming deposits on washed kitchen utensils by applying various additives in the detergent formulations, either by complexing the water hardness salts, or by formulating special rinsing agents. However, the incorporation of complexing and/or soil suspending agents in the liquid formulations create processing and formulation problems, while any of the special rinsing agents that have been disclosed heretofore must be packed and applied separately in the washing solution.
It has also been proposed to improve the drainage properties of dishwashing compositions by incorporating an agent, such as gelatin or casein, which allows the rinse water to "sheet-off" the utensil, thereby leaving the surface dry. This rapid "sheeting-off"
effect reduces the effort involved in drying the washed objects and also improves their final appearance in terms of minimizing or altogether obviating the spotting and filming associated with suspended soil and water hardness.
Applicants have unexpectedly discovered that a liquid detergent composition containing a relatively small amount of a copolymer of N-vinylpyrrolidone and dimethylamino-ethylmethacrylate, having specific molecular weight limitations~ and a small amount of an alkali metal salt of casein, e.g., sodium caseinate, when added to an anionic surfactant, nonionic surfactant, or mixtures thereof, provides an excellent washing and cleaning composition with much improved drainage properties so as to render the cleaned objects virtually free from spotting andtor filming.
The liquid detergent composition will generally contain from about 2% to about 50% by weight, preferably from about 10% to about 30%
by weight of the total composition of an anionic surfactant compound.
Among the suitable synthetic anionic surface active agents that may be present in the liquid dishwashing detergent composition are the water-soluble hydrocarbon sulfates having the general

After the rinse, the substrate was placed on a rack to dry. The time at which drainage began and the percentage of the surface area of the substrate that dried due to this drainage were recorded.
The degree of benefit arising from the agent is directly related to the time at which drainage begins and the percentage of the area dried by this drainage. The benefit produced by drainage modification increases with increasing drainage rate and increasing percentage area dried by the enhanced drainage, provided that the rinse ~ater film drains as a uniform sheet, and does not break up into water droplets which produce objectionable spotting.
