Abstract
Use of fatty amines of general formula: ##STR1## wherein R.sub.1 may be a hydrogen atom, or a straight or branched alkyl radical, saturated and containing 4 to 18 atoms of carbon and wherein R.sub.2 is a straight or branched alkyl radical, saturated and containing 4 to 18 atoms of carbon, together with surface agents, to obtain foaming mixtures leading to improved foams. 2 to 50% amines are added, with respect to the weight of the surface agents. Application in the field of fire extinguishing foams, drilling, and in the production of lightweight products.
Claims5
A method for improving the qualities of the foams obtained by foaming an aqueous solution of a surface agent of the anionic or amphoteric type, wherein the foaming is produced in the presence of 2 to 50% by weight, with respect to the weight of the said surface agent, of fatty amine of formula:
- ##STR3## wherein R.sub.1 is a hydrogen atom or a staight or branched alkyl radical, saturated, in C.sub.4 -C.sub.18, and R.sub.2 is a straight or branched alkyl radical, saturated, in C.sub.4 -C.sub.18.
Foaming agents permitting to obtain aqueous foams with improved properties, containing a surface agent of the anionic or amphoteric type and 2 to 50% by weight with respect to said surface agent of a fatty amine of formula:
- ##STR4## wherein R.sub.1 is a hydrogen atom or a staight or branched alkyl radical, saturated, in C.sub.4 -C.sub.18, and R.sub.2 is a straight or branched alkyl radical, saturated, in C.sub.4 -C.sub.18.
