Procter & Gamble has been awarded two new patents for transparent and clear personal cleansers.
In US Patent No. 11,904,034 B2 (Huan Wang, Mingxia Chan, Matthew Clair Ehrman, Singapore Anurag Makrandi), P&G has patented a transparent soap bar with a percent transmittance value of greater than approximately 40%. The bar soap contains a soap surfactant selected from the group consisting of alkali or alkaline earth metal, and ammonium salts of C6-C18 carboxylic acids; synthetic surfactant selected from the group consisting of an anionic surfactant, a nonionic surfactant, and mixtures thereof; a fragrance component that is comprised of ketone and/or aldehyde fragrance components; an amine component selected from the group consisting of a primary amine, a secondary amine, a tertiary amine, a substituted or unsubstituted 2-pyridinol N-oxide material, an amphoteric surfactant, and mixtures thereof; and an antioxidant salt selected from the group consisting of an alkali metal metabisulfite, an alkali metal sulfite, an alkali metal bisulfite and mixtures thereof.
P&G was also awarded US Patent No. 11,904,036 B2 (Brian Xiaoqing Song, Brooke Michele Cochran, Howard David Hutton, III, Andrei Sergeevich Bureiko, Peter Herbert Koenig), which covers a clear cleansing composition comprising an anionic surfactant; an amphoteric surfactant; cationic polymer; inorganic salts; and an aqueous carrier. The composition is substantially free of sulfate-based surfactant, does not form a coacervate prior to use, and has a viscosity of approximately 100 cP to 5,000 cP measured at 26.6°C.
