Table The figure shows the changes in conductivity, yield point and viscosity with changes in electrolyte and active ingredient concentrations. Figure ₁ shows the active ingredients consisting of 2 parts by weight of _sodium dodecylbenzenesulfonate and 1 part by weight of sodium _C12-18 alkyl 3 mole ethoxysulfate for various concentrations of sodium silicate with a Na2O:SiO2 molar ratio of 1/1.6. The conductivity of a 20.6% aqueous solution of The horizontal axis of the figure shows the amount of silicate in the composition expressed as weight percent solids. Added silicic acid solutions of between 0 and 7% produce substantially clear, optically isotropic compositions typical of the steps described herein. A stage composition is obtained between and which is cloudy and unstable and consists of non-space-filling flocs of spherulites. The composition of the stage according to the invention is obtained between. Although the composition is cloudy, it is a stable composition containing substantially space-filling flocs of spherulites, exhibiting a yield point and exhibiting only a single liquid phase upon high-G centrifugation. A step composition is obtained which contains non-space-filling flocs of G-phase spherulites. It can be seen that the stage composition is obtained in a conductivity trough near the first conductivity minimum. Figure 2 shows the effect of adding sodium nitrate to the same active ingredient aqueous system as in Figure 1. Beyond the step A, a second conductivity maximum is passed and then a second conductivity minimum is reached, which corresponds to the formation of a platelet composition by a step of approximately A. Figure 3 shows the changes in viscosity, conductivity and yield point when sodium carbonate is added to the same active ingredient system. The vertical axis on the left shows the viscosity at 136 seconds ^-1 (unit: Pascal-second), and the value in square brackets [ ] is the conductivity expressed in millisiemens cm ^{-2 (} mS-cm2). The vertical axis on the right side is the yield point (dyne cm ^-2 ). The horizontal axis is the total weight percent of sodium carbonate expressed as dry weight of sodium carbonate based on the total weight of the composition. In the case of sodium carbonate, no minimum value is found in conductivity (dashed line). The reason for this is that since the solubility limit of sodium carbonate has been reached, even if more sodium carbonate is added, it will only become suspended and the amount of dissolved sodium carbonate will not increase. Therefore no stages are observed. The rapid increase in yield point (right-hand peak) coincides with the onset of the phase at . This is a representative composition of the invention. Figure 4 shows the relative proportions of sodium dodecylbenzenesulfonate and coconut oil monoethanolamide in a composition containing sodium dodecylbenzenesulfonate, sodium tripolyphosphate, sodium carbonate and water in the ratio 0.2:0.5:0.1:1.0. Shows the effect of changing the ratio. The horizontal axis shows the weight ratio of coconut oil monoethanolamide/sodium dodecylbenzene sulfate, and the vertical axis shows the conductivity (mS・cm ^-1 ) (○ mark)
and viscosity (Pascal seconds x 10) (△ mark). Figure 5 shows coconut oil monoethanolamide at C _12-18
A relationship similar to that shown in FIG. 4 is shown when sodium alkyl 3 mole ethoxysulfate is used instead. The horizontal axis is the weight ratio of the above sodium ether sulfate/the above sodium alkylbenzene sulfonate. Figures 4 and 5 illustrate how compositions of the invention may be prepared by varying the active ingredients. Figure 6 contains suspended builder and has the following composition: wt % Sodium dodecylbenzenesulfonate 9 C _12-18 alkyl 3 moles Sodium ethoxy sulfate 4 Silicone defoamer 1 Fragrance 0.6 C _16-18 mixed mono/di -Alkyl sulfate 0.5 Fluorescent brightener 0.15 Sodium tripolyphosphate 19 Shows the conductivity (mS·cm ^-1 ) when sodium nitrate is added in various proportions to a detergent containing zeolite A 12 . No steps are visible in this graphical representation due to the sodium tripolyphosphate already present. The conductivity decreases from the maximum value at to the beginning of the stage at. Figure 7 shows the yield point (dyne cm) of the same system as in Figure 6.

Figure 9 shows the changes in the proportion of sodium silicate in a 20.6% by weight aqueous solution of sodium dodecylbenzenesulfonate, which is a mixture of sodium dodecylbenzenesulfonate and coconut oil monoethanolamide at a weight ratio of 10:4. Shows changes in conductivity. Again, no stages were observed. The reason for this is that the active ingredient is completely soluble in water even at room temperature. Therefore, the composition is cloudy and unstable in the absence of electrolyte. Figures 10 and 11 show Pt/C after freeze-fracture.
