Embodiment 1
[0091] A series of samples as described in Table 1 was prepared using the general procedure above (6 compositions per sample series; TAS was present in an amount of 0 (no TAS), 0.1, 0.2, 0.3, 0.4 or 0.5% by weight ).
[0092]
[0093] The viscoelastic properties of the compositions under harmonic oscillations were obtained using a TA ARES-G2 rheometer with a 50 mm parallel plate geometry (1 mm gap). Measurements were performed at 25°C. A frequency range of 0.01 to 100 Hz is applied to the composition at 1% strain, and the elastic modulus (G') and loss modulus (G") of the composition are measured as a function of frequency. The isotropic surfactant phase is where The primary surfactant microstructure is a surfactant phase of micelles of aggregated surfactant molecules. Preferably, the surfactant phase is an isotropic, rod-shaped micellar system, i.e., wherein the primary surfactant microstructure is a generally rod-shaped micellar system. For isotropic, rod-shaped micellar...
Embodiment 2
[0104] The compositions described in Table 2A were prepared according to the general procedure above. The pH of the composition ranges from 4.0 to 4.7. The respective initial viscosities of the resulting compositions were measured. Viscosity modifiers were post-added to the initially formed TAS-containing compositions (as indicated); sodium chloride was used to adjust viscosity up, or PPG-9 was used to adjust viscosity down. Based on the total weight of the initially formed composition, the viscosity modifier is post-added until an adjusted viscosity within the target viscosity of 4000 to 8000 cP is obtained, or the amount of viscosity modifier added reaches a maximum total amount. The viscosity modifier was post-added at 0.05% by weight up to a total of 0.2% by weight, and thereafter in 0.1% by weight increments up to a maximum total of 2.0% by weight. Sodium chloride was post-added to the TAS-free C1 and C2 compositions in increments of 0.2, 0.3 and 0.5% by weight, based o...
Embodiment 3
[0125] The compositions described in Table 3 were prepared by the general procedure described above and their initial viscosities were measured. The indicated amount of viscosity modifier was post-added to the initially formed composition and the viscosity of the final composition was measured. The final composition was stored at 45°C for 2 months and its viscosity was measured again. Viscosity was measured using the apparatus and conditions described above.
[0126]
[0127]
[0128] After 2 months at 45°C, the final compositions of Samples 7 to 12 were all within 15% of their fresh viscosities, and after storage, the final compositions of Samples 9, 10 and 11 were all within their fresh viscosities. Within 1% of viscosity.
