  • Patent number: 6682723
    Abstract: A paint containing a surfactant system capable of structuring a non-aqueous liquid composition, wherein the surfactant system comprises at least about 5% of a structuring particle. The surfactant system preferably further comprises a surfactant selected from the group consisting of anionic, nonionic, cationic, amphoteric surfactants and mixtures thereof. A well dispersed mixture of a non-aqueous liquid, for example, a nonionic surfactant, and at least about 25%, by weight of the surfactant system results in the mixture having a yield of at least about 2.0 Pa when measured at 20 sec−1 and 25° C. Moreover, the surfactant system should exhibit a peak when measured by SAXS x-ray diffraction, wherein the peak's center is between about the 1.5 to 2.5 v positions on the 2 theta axis. The structuring particles are most preferably structuring particles of sulfate and linear alkyl benzene sulfonate.
