The material that you ship contains 20% isopropyl alcohol,\nmore than 75% water, and less than 5% of various non-hazardous surfactants. Specifically, you\nask if the product described meets the exception for aqueous solutions of alcohol under the\nHMR.\nThe answer is yes. Aqueous solutions ofalcohol, that contain no other hazardous materials, are\nexcepted from the requirements ofthe HMR when they contain 24% or less alcohol by volume\nand no less than 50% water.\nI hope this information is helpful.
