Safety of MACS- treated soft surfaces for skin and respiratory exposure. Author: Jeffrey F. Williams The active ingredients in the MACS formulation are safe for prolonged skin contact, and do not cause irritation or sensitization. The major functional active is a registered US EPA biocidal compound. The polymeric agents used to enhance binding to fibers are US FDA-GRAS listed (Generally Regarded As Safe) and are safe enough to be incorporated into many consumer cosmetic and food products. An extensive review of the contact and environmental safety of the MACS active compound class is included in EPA Document-HQ-OPP-2013-0220-0008. A closely related compound in the class (more potent than the MACS components) is widely used as a sanitizer in millions of recreational hot tubs and spas in the US, with no indication of toxicity or allergic sensitization after decades of exposure of human subjects in this intimate way. When measured using an Interscan 4000 Portable Gas Meter equipped with a Cl-sensitive electrode, MACS-treated masks released active Cl atoms at a barely detectable rate of <0.003 micrograms of chlorine per minute. This results in an exposure that is insignificant in comparison to the US OSHA occupationally-allowed rate over a working day of 0.5 ppm in 240 L of inspired air (https://www.osha.gov/dts/sltc/methods/inorganic/id101/id101.pdf).
