Foam-forming composition utilizing zwitterionic polymeric foam intensifiers (stabilizers) to increase the volume of foam and / or alveolar omaterial and / or retention of foam and / or alveolar material in foaming and / or alveolar material forming compositions, and use thereof. Suitable foaming compositions and / or honeycomb material comprise one or more zwitterionic polymeric foam stabilizers which, in turn, comprise monomer units that have at least one part capable of maintaining a negative charge at a pH of 4. at 12 and at least one part capable of maintaining a positive charge within the same pH range. They are foaming compositions and / or honeycomb material, other than for dishwashing, such as champs, compositions for washing hands, body, hair, etc. laundry detergent compositions, especially laundry soaps and / or foam phosphate laundry compositions, hard surface cleaning compositions, foamy agrochemical compositions, foam flooring with oil and / or foamy extinguishing compositions fires. A preferred class of zwitterionic polymer suitable for use as a foam volume intensifier and foam duration has formula (1) where R is C1-12 linear alkylene, C1-12 branched alkylene and mixtures thereof, preferably C1-4 linear alkylene , C3-4 branched alkylene, more preferably methylene and 1,2-propylene. R1 and R2 are defined below. The x index ranges from 0 to 6; y is 0 or 1; z is 0 or 1. The index n has such a value that the zwitterionic polymers of the present invention have an average molecular weight of between 35,000 and 300,000 dalton. |
