  • Example 1 The formulation of Example 1 was used to form an abrasive wipe by impregnating a substrate having an abrasive surface (Tecnofibra T10, ex Tecnofibra, Italy) with the formulation at a formulation: substrate weight ratio of 2:1.
  • the abrasive wipe so formed was evaluated for its cleaning performance against a variety of typical kitchen and bathroom soils. Its streaks profile (i.e. any residues left behind after treatment of a surface with the wipe) was also measured using black ceramic and stainless steel tiles.
