Abstract
The surfactants of this invention are quaternary ammonium compounds based upon 2,4,7,9-tetramethyl-5-decyne-4,7-diol. These surfactants, not only decrease the surface tension of aqueous systems, but by virtue of the cationic nitrogen containing moiety have outstanding substantivity for hair, skin and textile fibers, lacking in the parent non-ionic.
