Abstract: An apparatus for corring aqueous surfactant composition and sampling moisture content wherein the apparatus includes a device for delivering composition to a main collection port; a device for coring the composition in the main collection port to form a sample; a device for delivering the sample into an NMR sensor area; a device for measuring moisture level of the sample in the NMR sensor area; and a device for extracting the sample from the NMR sensor area or returning the sample to a main collection port which includes a cross feed piston assembly.

Abstract: The present invention relates to detergent bar compositions comprising a specific ternary system. Specifically the composition comprises (1) about 10% to 70% of a first synthetic anionic surfactant and (2) 1 to 20% of a mixture of surfactants comprising a second anionic different from the first and an amphoteric surfactant, wherein the composition comprises less than 5% soap. In such compositions, the throughput rate of a bar made from processing the compositions through a plodder is higher at a temperature below 100.degree. F. than it is above 100.degree. F., said temperature referring to the temperature reading at just after said bar is extruded through said plodder.

Abstract: A process for preparing an aqueous surfactant composition comprising blending defined ingredients, heating and/or mixing, removing a sample to be sampled by a device containing an NMR, determining moisture level and releasing for further processing.
