Patent number: 7662855Abstract: Compositions for topical application for treating a skin disorder (e.g., acne) include a retinoid, which is solubilized completely in alcohol only with the aid of cosolvents such as esters (e.g., alkyl benzoate, isopropyl palmitate, isopropyl myristate, diisopropyl adipate and their derivatives). This completely solubilized retinoid can be used to formulate an emulsion system or liquid to powder suspension containing a second active, such as an antibiotic (e.g., clindamycin).Type: GrantFiled: November 9, 2004Date of Patent: February 16, 2010Assignee: Imaginative Research Associates, Inc.Inventors: Mohan Vishnupad, Naomi Vishnupad

Patent number: 6774100Abstract: Substantially anhydrous compositions having a viscosity greater than 1000 centipoise are prepared by combining a polar solvent with a thickening agent selected from the group consisting of acrylic acid polymers and polyacrylamides. These compositions are particularly suited for topical use to deliver beneficial agents to the skin of a user. Being anhydrous, the compositions are particularly well suited to effectuate the delivery of beneficial agents that are unstable over time in aqueous systems.Type: GrantFiled: December 6, 2000Date of Patent: August 10, 2004Assignee: Imaginative Research Associates, Inc.Inventor: Mohan Vishnupad

Patent number: 6462025Abstract: Two separate compositions, one containing an antibiotic and one containing benzoyl peroxide are packaged within and dispensed from a common dispenser. More particularly, a dual dispenser contains i) a first composition that is substantially anhydrous and includes a polar solvent, an antibiotic and a thickening agent selected from the group consisting of acrylic acid polymers and polyacrylamides; and ii) a second composition containing benzoyl peroxide or, alternatively, a retinoid. By packaging these two anti-acne active ingredients in this manner, long shelflife and convenient dispensing and application are provided.Type: GrantFiled: December 12, 2000Date of Patent: October 8, 2002Assignee: Imaginative Research Associates, Inc.Inventor: Mohan Vishnupad

Patent number: 5186857Abstract: The present invention relates to liquid, lotion-like aqueous oil-in-water dispersion compositons including emulsions containing large amounts of oil or oil/wax mixtures, a volatile organic foam-producing liquid, alone or in combination with foam suppressing agents, if necessary, to and surface active agent or agents which increase the solubility of the foam-producing liquid in the oil or oil/wax mixture. The present compositions are dispersions including mixtures which do not foam or self-dispense from a non-pressurized container at temperatures from RT to 120.degree. F., then can be poured onto a wet surface at room temperatures and spread to form a thin cleansing coating which will foam under ambient conditions to leave a residue of the oil or oil/wax mixture for cosmetic, medicinal, aesthetic, protection or other purposes.Type: GrantFiled: March 21, 1989Date of Patent: February 16, 1993Assignee: Imaginative Research Associates, Inc.Inventors: Jose E.
