Abstract:
A method of making aluminum salt compositions using a combination of a basic organic buffer with a source of alkaline earth metal ions. This selection of basic organic buffer provides for a lower alkaline earth metal salt content in the composition made by the method.
Abstract:
An antiperspirant active composition comprising an aluminum salt, the aluminum salt (i) having an aluminum to chloride molar ratio of 0.3:1 to 3:1; and (ii) exhibiting an 27Al NMR spectrum with a species distribution including at least 90% A130 polyhydroxyoxoaluminum cation as the predominant species detectable by 27Al NMR within the aluminum salt. The composition can optionally include zirconium. Also disclosed are a method of making an antiperspirant active composition and the use of a heating step at elevated temperature to convert Al13 polyhydroxyoxoaluminum cations in the species detectable by 27Al NMR within an aqueous aluminum salt solution into Al30 polyhydroxyoxoaluminum cations in the species detectable by 27Al NMR without increasing a SEC Peak 3 area in the SEC chromatogram of the aluminum salt.
Abstract:
An anhydrous liquid antiperspirant/deodorant composition comprising a carrier comprising a cation and/or zwitterion and a hydrogen bond donor, wherein an amount of carrier is greater than an amount of any other material in the composition, and an antiperspirant active. This represents a new delivery form for antiperspirant actives and/or deodorant actives.
Abstract:
An antiperspirant active composition comprising an aluminum salt having an aluminum to chloride molar ratio of about 0.3:1 to about 3: 1, exhibiting a SEC chromatogram having a SEC Peak 4 to Peak 3 intensity ratio of at least 7 and a Peak 4 intensity greater than a Peak 5 intensity in aqueous solution. The composition can optionally include zirconium. Also, methods and processes of making the same.
