<p>A-methyl cyanoacrylate (MCA) composition for use in female sterilization which provides improved inhibition and long-term storage i.e., longer "shelf-life" of monomeric methyl cyanoacrylate. The composition which exhibits both improved shelf-life and improved effectiveness for female sterilization consists essentially of MCA, an organic carboxylic acid ranging in amount from about 12,500 ppm to about 60,000 ppm, sulfur dioxide ranging in amount from about 500 ppm to about 1,500 ppm and a component selected from the group consisting of hydroquinone, hydroquinone monomethyl ether, butylated hydroxyanisole and mixtures thereof, the component ranging in amount from about 50 ppm to about 250 ppm.</p> |
