One year later ProNatural Brands received an EPA registration for a food contact sanitizer using naturally derived ingredients. One of their scientists then began developing other naturally derived formulations intended for the commercial cleaning market. They were told by a facilities director at a major university medical center that the environmental service personnel prefer to use less toxic and more environmentally friendly chemical cleaning products. The facilities director also remarked that harsh chemical cleaning products continually damaged the internal infrastructure (equipment, furniture, floors and walls) resulting in expensive annual replacement costs. ProNatural products were evaluated by the environmental services personnel at the medical center. They concluded that the ProNatural products, namely the food contact sanitizer and cleaner/degreaser, performed as well as their current products.
