In a statement sent to USA TODAY on Sunday, Justin Comes, vice president of research and development for Skittles maker Mars Wrigley North America, said the company couldn't comment on pending litigation – but that its use of titanium dioxide and all Mars Wrigley ingredients are safe and manufactured in compliance with strict quality and safety requirements established by food safety regulators, including the FDA.
Lithopone 30% has a lower coverage power than titanium dioxide. For this reason, Lithopone 30% can only partially substitute titanium dioxide, between 5 and 40%.
