Abstract
An oral composition of acceptable taste substantially non-irritating to oral tissue, the composition containing an effective amount of a sodium lauryl sulfoacetate surfactant purified to contain less than 18% by weight impurities. An amount of a nonionic or amphoteric compound is included in the composition to enhance the foaming ability of the purified sodium lauryl sulfoacetate surfactant as well as to further reduce its irritancy potential.
Claims16
A substantially non-irritating oral composition which is a dentifrice toothpaste, gel, dental cream, mouthwash or rinse of an acceptable taste, the composition being comprised of an effective amount of a sodium lauryl sulfoacetate surfactant purified to contain about 18% or less by weight impurities, and is substantially free of bitter tasting impurities as well as oral mucosa irritating sodium lauryl sulfate, the effective amount being a concentration of about 0.5 to about 5.0% by weight at which concentration the purified sodium lauryl sulfoacetate is found unexpectedly not to have the normal bitter taste associated with unpurified commercial sodium lauryl sulfoacetate.
The composition of claim i wherein the purified sodium lauryl sulfoacetate surfactant has the following analysis:
- ______________________________________ wt % range ______________________________________ dodecyl sodium sulfoacetate 82.0-85.0 min. sodium chloride 7.5-8.0 max. sodium sulfate 7.5-8.0 max. sodium sulfoacetate <4 max. free alcohol <0.6-0.8 max. ______________________________________
