• the sultaine, phosphine oxide, and amine oxide detergents impart superior detergency properties to the compositions of this invention.
• the preferred sultaine, amine oxide and phosphine oxide detergents impart cool, as well as hot, water detergency properties to the compositions. It is surprising that these surfactants do not detract from the excellent whiteness maintenance properties of the nonionic detergent surfactants when used in combination with the nonionic detergent surfactant. Sultaine detergents are preferred.
• the alkali metal pyrophosphates which form a part of the compositions of this invention are the conventional detergent builders found in built liquid detergent compositions.

• the emulsion is kept stable by the presence of the aforementioned specific emulsion stabilizers.
• the specific compositions described herein, and especially the compositions containing the sultaine detergents hereinbefore described are extremely sensitive to changes in the stabilizer and therefore the choice of stabilizers is considered to be critical.

• the specific emulsion stabilizers are particularly beneficial With respect to shipment conditions when the compositions are subjected to continuous shocks and agitation.
• the pH of the subject compositions must be maintained within the range 11.7 to 13.0. Failure to maintain the pH in this range can be disastrous with respect to product stability.

• Option-a1 ingredients include optical Whitening (brightening) agents. It has been discovered that only a limited number of optical whitening .agents are compatible in the compositions of this invention and particularly when the preferred sultaine detergents are used.
• Suitable optical brightening agents include at least one optical whitening agent selected from the 'group consisting of:
• compositions of this invention contain a quaternary ammonium salt, e.g., a quaternary ammonium germicide
• nonionic optical whitening agents are preferred.

• the above brighteners (optical Whitening agents) in the oily phase of the composition are considerably more compatible with the sultaine, phosphine oxide and amine oxide detergent surfactants (as well as cationic materials when they are present) when the composition is in the form of an oil-in-water emulsion as herein described, rather than a homogeneous aqueous solution.
• compositions can also contain from about 0.2% to 1.5% of soil suspending agents selected from the group consisting of alkali metal, ammonium and substituted ammonium carboxymethylcellulose and alkali metal, ammonium and substituted ammonium carboxymethylhydroxyethylcellulose. It is an advantage of the liquid detergent compositions of this invention that the more readily available carboxymethylcellulose salts can be used.
• the salts of car-boxymethylcellulose are less soluble than the salts of carboxymethylhydroxyethylcellulose and it is normally very difficult to use c-arboxymethylcellulose salts in liquid detergent compositions. By suspending the carboxymethylcellulose salts in the discrete phase, the problem of solubility is avoided.
• the carboxymethylcellulose can also be added by dissolving it in a silicate-water solution prior to adding it to the composition.
• germicides hereinbefore mentioned.
• Specific examples of such germicides include pentadecyl benzyl dimethyl ammonium chloride and tetradecyl diethyl methyl ammonium bromide.

• a pre-mix is formed containing the nonionic detergent surfactant; at least approximately one-fourth of the sultaine, phosphine oxide or amine oxide detergent surfactant; the optical whitening agents; the dyes, the carboxymethylcellulose and any caustic required to make the solution alkaline. These ingredients are mixed thoroughly.
• the emulsion stabilizer is prepared by hydrolyzing the copolymer described hereinbefore. A small amount of the nonionic detergent, about 2% to 80% by weight based on the amount of the unhydrolyzed emulsion stabilizer, is dissolved in water and then mixed with the emulsion stabilizer. The mixture is heated to from about 150 F. to about 200 F. to permit the emulsion stabilizer to hydrolyze which brings the pH down below 7. It is believed that the nonionic detergent surfactant reacts with the emulsion stabilizer to form an ester.
• the amount of nonionic detergent surfactant which is utilized in the hydrolysis of the emulsion stabilizer is very important since relatively minor changes in the amounts of the nonionic detergent surfactant cause very large changes in the viscosity of the final product.
• the use of larger amounts of nonionic detergent surfactant raises the viscosity.
• the hydrolyzed resin is made alkaline, preferably with either sodium hydroxide or potassium hydroxide.
• the pro-mix and the aqueous solution containing the hydrolyzed emulsion stabilizer are mixed together.
• Preferably at least a portion of the builder is added to the aqueous solution containing the emulsion stabilizer before the pre-mix is added to the aqueous solution.

• This dispersed phase is added to a solution of the emulsion stabilizer prepared as hereinbefore described and sodium acid pyrophosphate (or potassium acid pyrophosphate) in water and mixed thoroughly.
• Potassium or sodium hydroxide is then added as necessary to neutralize the sodium acid pyrophosphate; the other ingredients, e.g., the potassium nitrilo triacetate, potassium or sodium pyrophosphate, sodium silicate, etc., are added to this mixture.
