Abstract
The disclosure is directed to novel detergent compositions having polyalkoxylated amine foam stabilizers. The new foam stabilizers of the inventive detergent compositions build or enhance foaming and are particularly useful because of their surprisingly mild, non-skin-irritating characteristics. Mildness is a requirement of components to be included in or used in applications such as liquid dish detergents, hand cleaners and car washes.
