Health Canada is expanding its recall of certain hand sanitizers over fears the products may include industrial-strength ethanol, bringing the total now pulled back from the market to nearly two dozen.In a notice posted Friday afternoon, the department warns Canadians to be alert to the type of hand sanitizer as its recall list reaches 23 brands being recalled for containing the ingredient, which isn’t authorized for use in Canadian hand sanitizers.“Industrial-grade ethanol contains impurities that are not found in the type of ethanol approved for use in manufacturing hand sanitizers … In addition, chemicals that may not be approved for use in hand sanitizers are added to industrial-grade ethanol,” said the notice from Health Canada. .
