ABSTRACT:
Low foaming beta-amino propionic acid surface active agents are described having the following formula: ##STR1## where R is a C.sub.6 to C.sub.18 aliphatic hydrocarbon radical and n has an average value of from 0 to about 13.
The compounds of this invention produce only weak foams as compared with prior art beta-amino acids and have improved solubility and wetting properties over the entire pH range as compared to such prior art beta-amino acids. The compounds of this invention are particularly desirable for use either alone or in combination with other surface active agents and detergents in many washing and wetting applications where foaming is an undesirable characteristic. The compounds are also useful as emulsification agents.
