Abstract Hydroxyfunctional carboxamide compounds of formula I Image (I) are included in thixotropic formulations containing highly disperse silica as a thickening or thixotroping component in order to activate the silica or enhance its effect, to ameliorate any tendency of the silica to settle and/or to prevent weakening of the thixotroping effect of SiO2 in formulations which themselves form relatively strong hydrogen bonds. The compounds of formula I may be added to silica-containing thixotropic liquid formulations to improve the thixotropy, or highly disperse silica may be coated with such compounds for later incorporation into liquid systems to render them thixotropic. - 43 -
