Patent number: 11911496Abstract: The invention relates to stable, mild and moisturizing lamellar liquid cleansing compositions which possess a lotion-like appearance conveying signals of enhanced moisturization. However, these liquids often are either unstable or cause poor lather production and other sensory deficits The use of a specific ratio of total acyl isethionates to acyl glutamates or other divalent anionic surfactant in a structured liquid product improve stability and lather production, mildness and acceptable odor.Type: GrantFiled: August 31, 2022Date of Patent: February 27, 2024Assignee: Conopco, Inc.Inventors: Alyssa Nicole Kranzmann, Jamie Lynn Miller, Tirucherai Varahan Vasudevan

Patent number: 11904035Abstract: The invention relates to lamellar liquid composition comprising acyl isethionate, methyl acyl taurate, amphoteric and/or zwitterionic surfactant. Unexpectedly, applicants have found that, when ratio of isethionate to taurate is kept at about to 1:1, enhanced lather is achieved. Other criticalities include ratio of amphoteric and/or zwitterionic to anionic surfactant, total amount of surfactant, and pH.Type: GrantFiled: May 4, 2020Date of Patent: February 20, 2024Assignee: Conopco, Inc.Inventors: Douglas John Hiban, Jamie Lynn Miller, Tirucherai Varahan Vasudevan

Patent number: 11896699Abstract: The invention relates to aqueous skin cleansing compositions. Specific amounts and chain length of acyl glycinate and acyl glutamate when used in specified ratios, have been found to unexpectedly enhance lather volume and texture, as well as provide superior mildness.Type: GrantFiled: June 17, 2021Date of Patent: February 13, 2024Assignee: Conopco, Inc.Inventors: Yeyi Gu, Tirucherai Varahan Vasudevan, Kayla Marie Kemler, Adrienne Lyn King

Patent number: 11857508Abstract: The present invention relates to an isotropic concentrate composition that is easy to hydrate and transform into an end use wash composition. The end use wash composition resulting from the concentrate composition is suitable for topical application and for hand washing. The concentrate comprises fragrance oil and emulsifier at levels that unexpectedly result in a concentrate composition and end use composition that are free of ingredient precipitation that interferes with the appearance and usage of the compositions.Type: GrantFiled: January 20, 2021Date of Patent: January 2, 2024Assignee: Conopco, Inc.Inventors: Douglas John Hiban, Tirucherai Varahan Vasudevan, Mingchang Ye

Publication number: 20230398050Abstract: The invention is directed to a stable composition wash composition. The wash composition comprises a mixture of naturally derived and biodegradable sulfated polysaccharides. The wash composition has a viscosity of 40,000 cps or less, and surprisingly, is free of syneresis, discoloration and malodor, even after being stored at elevated temperatures.Type: ApplicationFiled: November 8, 2021Publication date: December 14, 2023Applicant: Conopco, Inc., d/b/a UNILEVERInventors: Douglas John HIBAN, Tirucherai Varahan VASUDEVAN
-
Publication number: 20230149273Abstract: The invention is directed to a stable, high polyol containing wash composition. More particularly, the invention is directed to a wash composition comprising polyol, surfactant and a gelling agent whereby the wash composition is air pocket free, has excellent moisturizing capabilities, a viscosity of 40,000 cps or less, and a slope from ?0.5 to 0.0. The isotropic composition has an oil-like appearance.Type: ApplicationFiled: February 26, 2021Publication date: May 18, 2023Applicant: Conopco, Inc., d/b/a UNILEVERInventors: Zhaowei DING, Kerin Frances JACOB, Tirucherai Varahan VASUDEVAN
-
Publication number: 20230049117Abstract: The invention is directed to a hydratable concentrated surfactant composition. The composition is pourable, easy to dilute, substantially free of sulfate and oil, comprises a C6-C14 acid, alcohol or both, an anionic surfactant comprising acyl isethionate and an amphoteric surfactant, zwitterionic surfactant or both. The composition is in lamellar phase and thickens and transforms to an isotropic phase upon dilution. The composition can be used as a concentrate in small volumes and diluted as used and needed or can be diluted with water in refill packaging to ensure a reduction in plastic waste.Type: ApplicationFiled: January 20, 2021Publication date: February 16, 2023Applicant: Conopco, Inc., d/b/a UNILEVERInventors: Douglas John Hiban, Teanoosh MOADDEL, Daniel Filipe PEREIRA, Tirucherai Varahan VASUDEVAN
-
Publication number: 20230014087Abstract: The invention is directed to a foam precursor liquid and foam cleansing composition that comprise a cellulose ether and surfactant. The precursor liquid results in a foam with excellent lather characteristics upon dispensing from a pump foam dispenser, and the liquid does not thicken to impede or clog the dispenser it is dispensed from. The foam precursor liquid is easily pourable prior to dispensing and makes refilling and reusing pump foam dispensers very convenient for consumers conscious about using less plastic.Type: ApplicationFiled: October 29, 2020Publication date: January 19, 2023Applicant: CONOPCO, INC., d/b/a UNILEVERInventors: Tirucherai Varahan VASUDEVAN, Zhaowel DING
-
Publication number: 20230000743Abstract: The invention is directed to a composition suitable for topical application that comprises a naturally derived preservative having benzoic acid or a derivative thereof. The composition is stable when preserved with the naturally derived preservative and when at a pH that is above the natural pH of skin to as high as 7.25.Type: ApplicationFiled: August 5, 2022Publication date: January 5, 2023Applicant: Conopco, Inc., d/b/a UNILEVERInventors: Kimberly Day, Morgan Nicole Kozar, Matthew Joseph Rienzo, Tirucherai Varahan Vasudevan
