Abstract

Wet-like cleaning wipes and similar articles are described. These wipes comprise a carrier that provides controlled fluid absorbency and an emulsion applied to the carrier. The emulsion comprises a continuous external lipid phase and a polar (e.g., water) internal phase. The emulsion is sufficiently brittle that it ruptures when subjected to low shear pressures during use to release the dispersed polar phase. The carrier allows the released internal phase to initially reach and remain on the surface being cleaned, but then absorbs the material at the end of the wiping process.
