  A detergent composition with especially good foaming properties includes a di(C7-C9) alkyl sulphosuccinate, preferably a di(C8 alkyl) sulphosuccinate, and an unsymmetrical dialkyl sulphosuccinate in which one alkyl group is C7-C9 and the other is C3-C6, preferably a (C6 alkyl) (Ce alkyl) sulphosuccinate. A di(C3-C6) alkyl sulphosuccinate may advantageously be present. An especially preferred mixture comprises di(n-octyl), (n-octyl n-hexyi) and di(n-hexyl) sulphosuccinates. and this mixture may be prepared by esterifying maleic anhydride or the like with a mixture of n-octanol and n-butanol, followed by bisulphite addition. The detergent composition is preferably in liquid form and is suitable for shampoos, fabric washing and, in particular, manual dishwashing.

  The present invention relates to processes for preparing a stable suspension of carbon nanoparticles in a thermal transfer fluid to enhance thermal conductive properties, viscosity, and lubricity. One process is to disperse carbon nanoparticles directly into a thermal transfer fluid and other additives in the present of surfactants with intermittent ultrasonication. The second process is carried out in three stages. First, carbon nanoparticles are dispersed into a volatile solvent. Then, a thermal transfer fluid, surfactants, and other additives are added into this intermediate dispersion and mixed thoroughly. At last, the volatile solvent is removed to produce a uniformly dispersed nanofluid. The third process is to disperse carbon nanoparticles at an elevated temperature into a homogeneous mixture of surfactants and other additives in a thermal transfer fluid with help of a physical agitation. The present invention also relates to compositions of carbon nanoparticle nanofluids, such as nanolubricants and nanogreases. The nanofluid of the present invention is a dispersion of carbon nanoparticles, particularly carbon nanotubes, in a thermal transfer fluid in the present of surfactants. Addition of surfactants significantly increases the stability of nanoparticle dispersion. For nanogreases, carbon nanoparticles function both as a thickener to modulate viscosity and as a solid heat transfer medium to enhance thermal conductivity and high temperature resistance.
