The most hazardous substances that are released from silicones during condensation reactions include n-butanonoxime (suspected of carcinogenic effects and of causing sensitisation), as well as amines. The former are released from (neutral) oxime-cure systems, and the latter from (alkaline) amine-cure systems. As alternatives to neutral silicones, alcohol-cure systems can be used, which, in these concentrations, do not release many problematic alcohols (ethanol or methanol), as well as acid/acetate/acetic-cure systems (which are state of the art in sanitary use), which release small amounts of acetic acid. In the case of hybrid SMP, small amounts of alcohols are released as well, which do not pose health risks.
Oxime- and amine-cure silicones must not be used.
