The Brenneman Corporation has filed its response to the class-action lawsuit alleging severe allergic reactions to Brenneman’s All-Natural Hand Soap and Paint-Stripping Liquid. According to the filing, the product is labeled “Hyper-allergenic” in large letters on the front of the package, with an exclamation point; and if purchasers do not know the difference between “hypo” and “hyper,” their ignorance cannot be laid at the feet of the company.
