Patent number: 11104865Abstract: The invention is in the field of hard surface cleaning compositions. There is need for compositions that foam copiously during the washing/cleaning stage. However, during the rinse stage, the foam should rinse-off as quickly as possible in minimum number of rinses-cycles so that the process becomes sustainable. Disclosed is an aqueous cleaning composition, having a pH of 6.5 or lower, comprising (i) 3.0 to 25.0% by weight alkyl ethoxy sulphate; (ii) 1.0 to 5.0% by weight amphoteric surfactant; (iii) 0.1 to 1.0% by weight fatty acids being saturated non-hydroxy C8-12 fatty acid and a saturated non-hydroxy C14-18 fatty acid, where ratio of amount of said C8-12 fatty acid to that of said C14-18 fatty acid is from 1:0.1 to 1:10 parts by weight; and (iv) 0.5 to 5% by weight non-ionic surfactant, wherein (iii) and (iv) together an antifoaming system, and wherein amount of non-alkoxylated anionic surfactant in said composition in less than 1.0% by weight.Type: GrantFiled: January 26, 2017Date of Patent: August 31, 2021Assignee: Conopeo, Inc.Inventors: Punam Bandyopadhyay, Maheshwara Shiva Naik

Patent number: 10443020Abstract: The invention is in the field of cleaning compositions. There is need for compositions that foam copiously when articles are washed. However the foam should rinse-off as quickly as possible in minimum number of rinses-cylces so that the process becomes sustainable. Disclosed is an aqueous cleaning composition comprising: (i) total Active Detergent (AD) level of 5 to 30% by weight, of which at least one-third is non-soap anionic surfactant; and, (ii) 0.1 wt % to 2 wt % of an antifoaming system containing saturated hydroxy fatty acid and saturated non-hydroxy C14-18 fatty acid, where the ratio between the amount of said saturated hydroxy fatty acid to that of said saturated non-hydroxy C14-18 fatty acid is from 1:0.75 to 1:5 parts by weight and where the pH of said composition is from 2 to 7.Type: GrantFiled: November 16, 2016Date of Patent: October 15, 2019Assignee: Conopco, Inc.Inventors: Punam Bandyopadhyay, Jiji Paul Kottukapally, Maheshwara Shiva Naik

Patent number: 9717666Abstract: The invention relates to a skin lightening composition, more particularly a composition which derives synergy between an active of natural origin and an active of synthetic origin. The present inventors have judiciously combined a selective salt of a dicarboxylic acid viz. disodium fumarate along with a specific extract of a plant source e.g. Salvia officinalis rich in certain organic aromatic acids to provide for synergic skin lightening benefits. They have further found that inclusion of certain activity enhancers in the composition of the invention improves the skin lightening efficacy.Type: GrantFiled: April 23, 2012Date of Patent: August 1, 2017Assignee: Conopco, Inc.Inventors: Punam Bandyopadhyay, Sujeetkumar Jha, Shilpa Atul Vora, Anita Damodaran

Patent number: 9283170Abstract: The present invention relates to a personal care composition for topical application having a skin lightening application. It is an object of the present invention to provide for a personal care composition that comprises fractions obtained from natural sources that gives enhanced skin lightening as compared to known fractions from natural sources.Type: GrantFiled: May 13, 2011Date of Patent: March 15, 2016Assignee: Conopco, Inc.Inventors: Punam Bandyopadhyay, Vishi Bansal, Vijay Ramchandra Gadgil, Rezwan Shariff, Ravi Kant Shukla

Publication number: 20150010483Abstract: The invention relates to a photo-stable sunscreen composition comprising a sunscreen stabilizer. It is an object of the present invention to provide a highly photo-stable sunscreen composition preferably extractable from a natural material while ensuring prolonged efficacy of the UV-A organic sunscreen used therein. The present inventors have achieved this by including Tanshinone IIA which is a diterpenoid othroquinone, which is present in certain plants, to achieve the desired sunscreen stabilisation.Type: ApplicationFiled: December 14, 2012Publication date: January 8, 2015Applicant: CONOPCO, INC., D/B/A UNILEVERInventors: Ravi Kant Shukla, Vijay Ramchandra Gadgil, Punam Bandyopadhyay, Lin Li

Publication number: 20120195840Abstract: The present invention relates to a personal care composition for topical application comprising selective fractions of natural materials having photoprotective and skin lightening applications. The inventors found that certain fractions of natural materials which are rich in anthroquinones or naphthaquinones e.g. those from the Rubiaceae family provide for enhanced broad spectrum photoprotection especially in the visible range while also exhibiting enhanced activity in a biochemical pathway viz. ty-rosinase inhibition which is indicative of improved skin lightening.Type: ApplicationFiled: September 21, 2010Publication date: August 2, 2012Inventors: Ravi Kant Shukla, Vijay Ramachandra Gadgil, Punam Bandyopadhyay, Anil Shankaranarayana Hegde
