example 1
[0147] Example 1 - Preparation and Measurement of Certain Compositions of the Invention (E1-E9)
[0148] Compositions E1-E9 were prepared according to the following procedure: Unless otherwise indicated, all materials were added at the weight % indicated for each composition in Tables 1 and 2, the specific polyglyceryl nonionic used for each composition Surfactants, zwitterionic surfactants and anionic surfactants are those also shown in Table 1 and Table 2. Add 60 parts of water, sodium benzoate and sodium chloride (if available) to an appropriately sized vessel equipped with a hot plate and overhead mechanical stirrer. While mixing at 200-250 rpm and heating to 40-50°C, add the polyglyceryl nonionic surfactant. The zwitterionic and anionic surfactants are added and the batch is mixed at 40-50°C until homogeneous. The batch was mixed and cooled to below 30°C before it was adjusted to the desired pH (pH=4.5-4.9) with the necessary amount of citric acid and / or sodium hydrox...

[0157] Example 2 - Preparation and Measurement of Certain Compositions of the Invention (E10-E11)
[0158] Compositions E10 and E11 were prepared according to the procedure of Example 1 with the additional steps of adding glycerin with water and sodium benzoate, and adding any nonionic surfactants (such as coco for E11 ) along with zwitterionic and anionic surfactants. oleyl glucoside). The materials and amounts of E10 and E11 are shown in Table 4. Zero shear viscosity, maximum lather volume, turbidity, TEP, and average micelle size were measured as described above and reported in Table 5.

[0163] Example 3 - Preparation and Measurement of Comparative Compositions (C1-C3)
[0164] Comparative compositions C1-C3 were prepared according to the procedure of Example 2, except that no polyglyceryl nonionic surfactant was added. The materials and amounts of C1-C3 are shown in Table 6. TEP and average micelle size were measured as described above and reported in Table 7. Applicants note that the comparative examples were normalized to have the same surfactant concentration (% by weight) as the corresponding inventive examples (e.g., C1 corresponds to E2 without polyglyceryl nonionic surfactant and is normalized to to have a comparable surfactant concentration (14.28% by weight active substance); C2 corresponds similarly to E3; and C3 corresponds to the polyglyceryl nonionic surfactant replaced by the alkyl polyglucoside nonionic surfactant E2.
