Definitions

  • the present invention relates to the use of betaine as a foaming agent and a foam drainage reducing agent.
  • the present invention also relates to the implementation of betaine in processes involving the presence of foam.
  • foams are also used in fire suppression products. Foams are also used to generate light and / or porous materials: the material cures from the bubble wall forming composition, resulting in a structure comprising pores corresponding to the bubbles. Foams are also used to suspend and transport cuttings in construction operations, in the field of building and public works, particularly in excavation operations and / or tunnel drilling. Foam is also used as a visual marker on terrain. Foams are also used in the treatment of water as a depollution agent to remove particles or soiling.
  • anionic surfactants including alkyl ether sulfates, which have a useful detergency and generate a preferred foam.
  • a zwitterionic surfactant, cocoamidopropyldimethylbetaine, is also known and widely used.
  • the processes described above may require a relatively long lifetime of the foam, otherwise the operations and phenomena can not be completed or their effectiveness diminished.
  • the foam must remain present during the hardening time. The sooner the foam drains, the less pores will induce lightness and / or the desired porosity. In excavation operations, the earlier the foam disappears, the less material will be evacuated.
  • the invention responds to this need by proposing the use in a foaming aqueous composition, as foaming agent and agent for reducing the drainage of the foam, of a betaine surfactant chosen from the following:
  • R 1 represents a linear or branched, saturated or unsaturated alkyl group comprising from 16 to 24 carbon atoms
  • R ' 1 represents a linear or branched, saturated or unsaturated alkyl group comprising from 15 to 23 carbon atoms
  • - R 4 represents a divalent C 1 -C 4 alkyl group, optionally substituted with a hydroxyl group
  • - R 2 and R 3 which may be identical or different, represent a C 1 -C 2 alkyl group, optionally substituted with a hydroxyl group.
  • agent of the invention or "betaine surfactant”.
  • the invention also relates to a process for the preparation of foam in which the aqueous composition comprising the agent of the invention is foamed, for example by stirring and / or propelling with the aid of a gas.
  • the invention also relates to processes comprising a step of preparing foam and another step, simultaneous or subsequent. These may be industrial processes or operated in the private domain. The interest is particularly marked in the context of industrial processes.
  • the invention makes it possible in particular:
  • the agent of the invention provides in particular an excellent compromise between the amount of foam generated and its duration over time.
  • drainage is meant the flow of the water contained in the foam, which can lead to the degradation of the walls of the bubbles and finally to the gradual return to the state of aqueous composition free of bubbles.
  • the composition is an aqueous composition comprising the agent of the invention.
  • the agent of the invention has the ability to generate foam.
  • the foam can be generated by any conventional method, including agitation, relaxation, implementation of a propellant, implementation of an aerosol device etc.
  • the generated foam is low drainage. It is therefore an agent both foaming and reducing drainage.
  • the composition may comprise a foaming agent other than betaine surfactant. If this is the case, the weight ratio between the betaine surfactant and the other foaming agent is preferably greater than 4, preferably greater than 5, preferably greater than 10.
  • the composition is free of other foaming agent.
  • the composition comprises less than 0.1% by weight, preferably less than 0.05%, preferably not at all other foaming agent.
  • the generation of foam and the low drainage may therefore be, under the invention, the consequence of the agent of the invention substantially alone.

  • R 2 and R 3 are methyl groups
  • R 4 is the group -CH 2 -CH 2 -CH 2 -. advantageously:
  • R 1 represents an alkyl group, linear or branched, saturated or unsaturated, comprising from 18 to 22 carbon atoms
  • - R ' 1 represents an alkyl group, linear or branched, saturated or unsaturated, comprising from 17 to 21 atoms of carbon.
  • the groups R 1 and R ' 1 can correspond to residues of fatty acids, generally of natural origin, most often vegetable.

  • the group R ' 1 may correspond to a linear or branched, saturated or unsaturated fatty acid comprising from 15 to 23, preferably from 17 to 21, carbon atoms.
  • the group R 1 may correspond to a linear or branched, saturated or unsaturated fatty acid comprising from 16 to 24, preferably from 18 to 22, carbon atoms. It is customary to assimilate the groups R 1 and R ' 1 to the fatty acid to which they correspond.
  • fatty acids and groups are known. These are generally derived from vegetable oils. They can be present in mixtures. In the case of mixtures, all the groups (or corresponding fatty acids), irrespective of the number of carbon atoms, are included in the definition if the group (or corresponding acid) predominates in weight (relative majority, preferably absolute, preferably at least 75%) corresponds to the definition. It is common to reduce the name to the group (or corresponding acid) group (or acid) majority.

  • the invention makes it possible in particular to maintain a low drainage at relatively high temperatures, for example between 40 0 C and 80 0 C, which makes it particularly useful and advantageous in certain processes operated at relatively high temperatures.
