Patent number: 5911981Abstract: Surfactant blends that generate a stable spherical foam are disclosed. The surfactant blends contain a nonionic surfactant or an amphoteric surfactant as the principal foaming agent, and a sufficient amount of an acylate lactylate to enhance foam volume and provide a foam that remains in a spherical form for up to about forty minutes. A method of generating a long-lasting foam also is disclosed.Type: GrantFiled: October 24, 1997Date of Patent: June 15, 1999Assignee: R.I.T.A. CorporationInventors: Gerd H. Dahms, James W. Cook

Patent number: 5885563Abstract: A shaving emulsion for an electric shaver is provided, which comprises water, n-decyl glucoside as a surfactant, and 2,2,4,4,6,8,8-heptamethylnonane (isohexadecane) as a lubricant. The shaving emulsion has excellent shaving properties, and is compatible with lacquer, printings and plastic, electrical, rubber and metal parts of the electric shaver. The mixture ensures that the shaving head can be very effectively rinsed and cleaned with water, so that an electric shaver which comprises a container in the form of a flexible plastic pouch (1) filled with such a shaving emulsion, is hygienic in use.Type: GrantFiled: September 23, 1997Date of Patent: March 23, 1999Assignee: U.S. Philips CorporationInventor: Cornelis P.G.M.
