Acrylic acid CAS No. 2-Propenoic acid homopolymer 5. No carcinogenicity or mutagenicity data on acrylic acid, methyl acrylate or polyacrylic acid were available to the Working Group. No mutagenicity data on ethyl acrylate were available to the Working Group.
Acrylic acid is embryotoxic and teratogenic.
No case reports or epidemiological studies relating to the carcinogenicity of acrylic acid, methyl acrylate, ethyl acrylate or polyacrylic acid were available to the Working Group. Acrylic acid is used primarily for the production of acrylates and polymers, and human exposure may be expected to occur. The use of methyl acrylate, ethyl acrylate and polyacrylic acid in a variety of textile, surface coating and other applications suggests other occupational exposures. The data available to the Working Group do not permit an evaluation of the carcinogenicity to humans of acrylic acid, methyl acrylate, ethyl acrylate or polyacrylic acid. The Working Group noted the absence of data on carcinogenicity and mutagenicity for this group of substances and considered that suitable experiments should be undertaken.
