Abstract
Aqueous foam compositions comprising water and a mixture of ammonium lauryl sulfate, methyl polyoxyethylene cocoamine chloride, dimethyl cocoamine oxide and polyvinyl alcohol are used to suppress the formation of fumes from fumable materials by covering the material with said compositions in the form of foam, thereby causing the material to react with the water to prevent fume release.
