Patent number: 6566319Abstract: Cleaning compositions, especially laundry detergents and the like, comprising (i) modified alkylarylsulfonate surfactants, e.g., modified alkylbenzenesulfonates, which are the product of particular processes and (ii) cleaning adjuncts such as enzymes and bleaches. Processes for making the cleaning products, including processes comprising vinylidene olefin production, alkylation of arenes, sulfonation and domestic cleaning product formulation. VO production is used to introduce particular limited branching into an alpha-olefinic feedstock which, converted to dimer form, has from about 10 to about 16, preferably from about 12 to about 14 carbon atoms. Preferred processes maximize the amount of vinylidene olefin useful for detergent manufacture, and minimize deep internal olefin production.Type: GrantFiled: January 7, 2000Date of Patent: May 20, 2003Assignee: The Procter & Gamble CompanyInventors: Jeffrey John Scheibel, Kevin Lee Kott, Thomas Anthony Cripe, Daniel Stedman Connor, James Charles Theophile Roger Burckett-St. Laurent
