Question: What is the amount of flavour used on the condom? Will the flavour affect or dissolve the condom especially if kept long before use? Answer by R&D Manager: The flavour content is about 0.5% of the condom weight. Our flavoured condoms have a shelf life of 5 years which means that the condoms physical properties remain compliant to the ISO 4074 standard requirements for the shelf life which is 5 years from manufacturing date subject to the storage conditions as stated on the pack being complied with. Keeping the condoms in a cool environment is important as temperatures exceeding 35°C can deteriorate the condoms faster.
