McNeil Nutritionals, Fort Washington, a division of McNeil-PPC Inc., says its Splenda[r] No Calorie Sweetener has become the top-selling low/no-calorie sweetener in United States retail outlets just two and a half years after its introduction. Splenda products, which include granular and packets sold at retail, had a 32.7% dollar share of the retail sugar substitutes market for the 12-week period ending April 20. That compares to 28.1 % for its closest competitor. Splenda has now led the market for 13 of the last 15 weeks. "Splenda¿as become the leader because consumers have responded so well to its taste and its versatility," said Debra Sandler, worldwide group v.p. marketing & strategic ingredient technology for McNeil Nutritionals. "People are learning that they can have the best of both worlds--the sweetness they love, without the calories or unpleasant aftertaste." Splenda, the brand name for sucralose, was launched into the consumer market in September 2000.
