This invention concerns foaming aqueous compositions of body-cleansing agents containing anionic surfactants (A) with a strong foaming action and alkyl- (oligo)-glucosides (B) which are easily tolerated by the skin and a , combination of a zwitterionic surfactant (C) e.g. a betaine surfactant, and , an ampholytic surfactant (D) e.g. a cocoamphoglycinate, to improve foaming properties and viscosity. Combining betaine and ampholytic surfactants yields a particularly creamy foam structure, consisting of particularly tiny bubbles when using said compositions.

Why it's free to use
- Filed November 24, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 24, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 24, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
