Contacted Mrs. Meyers to find out % acetic acid in product that intrigued me: lemon verbena vinegar gel. I guess the CA Cleaning Products Right to Know Act does not include percentage. They told me it is proprietary info, lol. Under the part 3 composition section of the MSDS: in lieu of list “For additional information on product ingredients, see www.caldrea.com.” so I guess that is a sister company which does not have the info. #cleaning#vinegar#aceticacid
