Composition for cleaning or rinsing hard surfaces

49) A composition for the cleaning or the rinsing in an aqueous or aqueous/alcoholic medium of hard surfaces comprising at least one surface-active agent and at least one polybetaine (B), said polybetaine (B), said composition:

• carries, within a pH range from 1 to 14, a permanent anionic overall charge and a permanent cationic overall charge, each individual betaine unit carrying as many permanent anionic charges as permanent cationic charges, and
• exhibits an absolute weight-average molar mass (Mw) ranging from 5000 to 3 000 000 g/mol, preferably from 8000 to 1 000 000 g/mol, very particularly between 10 000 and 500 000 g/mol.

76) A process for cleaning or rinsing hard surfaces in an aqueous or aqueous/alcoholic medium, comprising the step of treating said surface with an efficient amount of a composition comprising at least one surface-active agent and at least one polybetaine (B)

• carrying, within a pH range from 1 to 14, a permanent anionic overall charge and a permanent cationic overall charge, each individual betaine unit carrying as many permanent anionic charges as permanent cationic charges, and
• exhibiting an absolute weight-average molar mass (Mw) ranging from 5000 to 3 000 000 g/mol, optionally between 10 000 and 500 000 g/mol,
• contributing to said surfaces antideposition and/or antiadhesion properties with regard to soiling substances capable of being deposited on said surfaces.
