The sale of the Ariel and Magistral brands fell: Procter & Gamble will have to find a new buyer. The operation had been closed in September and the buyer was the Argentine company Dreamco.

"The conditions are not met to proceed with the acquisition," the firm now said. A group of the 400 workers involved reportedly resisted the change in conditions resulting from the operation. The company, which settled in the country in the early 90s, has the Villa Mercedes plant, San Luis, where it produces diapers.
