-20- TERTIARY DI-(.beta.-HYDROXY ORGANO)AMINE OXIDES AND THEIR PREPARATION ABSTRACT OF THE DISCLOSURE Disclosed are tertiary amine oxides which comprise an amine oxide nucleus substituted with an organic group and with two hydroxy groups which have carbon atoms in at least the .alpha., .beta. and y positions, a hydroxyl group on the .beta. -carbon atom, and have an effective chain length of at least 4 carbon atoms, said amine oxide being capable of being provided in ostensibly anhydrous form and being capable of being made at a concentration by weight of at least about 80% by oxidizing the corresponding tertiary amine with an oxidizing agent without solvent and withoutgelling during said oxidation. The novel tertiary amine oxides are useful as foam stabilizers, for example in stabilizing a foam of an alkyl benzene sulfonate foaming agent.
