Isotropic liquid detergent compositions containing ethoxylated nonionics and amine oxide surfactants, water soluble sequestering builders and a further hydrophilic surface-active agent are disclosed. These compositions provide superior detergency over a wide range of conditions including cold water detergency.

A process for the oxidation of nonaromatic tertiary amines to the respective amine oxides. An aqueous solvent system containing the tertiary amine is formed with an initial pH about equal to or greater than the pKa of the tertiary amine. In the absence of an oxidation catalyst, this aqueous system is contacted with gaseous molecular oxygen at an oxygen partial pressure of at least about 50 psi and a temperature of at least about 80°C. The resulting oxidation converts the tertiary amine to the respective amine oxide in fairly high yields without significant formation of other reaction products.

The present disclosure provides methods for generating percarboxylic acid compositions and/or peroxycarboxylic acid compositions formed external to a point of use in non-equilibrium reactions for use in certain bleaching and antimicrobial applications, in particular laundry applications. The compositions are generated external to a point of use, at alkaline pH levels, viz. greater than about pH 12, and optionally suitable for use with detergents and/or surfactants for synergistic bleaching efficacy. Methods of bleaching and/or disinfecting are further provided.
