Kimberly-Clark cut annual sales and profit forecasts on Tuesday and said false claims about its diaper quality in China will continue to be a problem after hurting second-quarter sales. The Kleenex maker cited independent testing by a government-certified third party to refute Chinese social media claims that its Huggies diapers contained formamide. Chinese media reported in June that Huggies and two Chinese brands Babycare and Bibabebe tested positive for the toxic substance that can irritate the skin, eyes and breathing if inhaled. …The China hit overshadowed broader progress in Kimberly-Clark’s cost-saving and transformation efforts, adding another challenge to the company, which, like its peers, is grappling with meeting the needs of financially stretched consumers. Last month, Kimberly-Clark finalized a 51% stake sale in its international tissue business to Suzano, creating the $3.4 billion Arbex joint venture to compete with rivals Procter & Gamble and Essity.
