SAPs are inert materials that have undergone extensive toxicity testing, demonstrating an exceptionally low toxicity profile for direct skin contact in humans. SAPs are used in baby diapers and feminine hygiene products, consumer markets that have extremely low tolerances for toxins due to the products’ intimate contact with human skin.
Further supporting the low toxicity of SAPs was the U.S. Food & Drug Administration’s 2001 approval of sodium polyacrylate SAPs for use as in indirect food contact. Following approval, SAPs became widely adopted for use in meat and poultry packaging. Not only are SAPs safe on their own, SAPs make food safer for consumers by absorbing blood and other fluids from meat that would otherwise present an ideal medium for the growth and spread of dangerous bacterial pathogens.
As an environmental waste treatment reagent, SAPs absorb and retain potentially harmful industrial fluids, preventing the leaching of contaminants into groundwater, surface water, soil, wildlife habitats, and landfill leachate.
