A B S T R A C T Novel rubber latex compounds comprise an aqueous dispersion of a natural or synthetic rubber latex and as a foaming agent an alkyl alkoxy sulpho- succinamate of the formula:- Image wherein R represents an alkyl group having from 7 to 18 carbon atoms, one of X and Y represents a hydrogen atom and the other represents a sulphate group, n is an integer having a value of from 0 to 5 and R1 represents an alkylene group comprising 2 or 3 carbon atoms. These foaming agents com- bine the virtues of acceptable foaming properties with relatively high solubility in aqueous solution. They can be prepared and transported as aqueous concentrates containing up to 45% of solids material. Those co pounds wherein R represents a branched chain alkyl group are believed to be novel and are claimed as such.
