I have been working with epoxy resin for several months - jewelry created at home, but in a separate room. The one I buy is non-toxic (according to GHS06 and GHS08), solvent-free and does not contain bisphenol. Despite this, I use all safety measures - mask, glasses, gloves. The room at the "robot" is ventilated, but recently I began to wonder if it is possible that working with resin in these conditions could somehow affect the effectiveness of bisyntactic contraceptive pills. (They are stored in a completely different room in the original packaging) - I have been using them for over 3 years My guess is that no studies have ever been conducted in this respect, but I prefer to ask pharmacists if any ingredient could still affect the effectiveness? I send below the information: "Resin: Product reaction: bis-[4-(2,3-epoxipropoxi)phenyl]propane Oxiran, Mono[(C12-14-alkyloxy)methyl]derivate" "Harden: Product reaction: 3-aminomethyl-3,5,5-trimethyl-cyclohexylamin" Please reply quickly.
