Why do spermicide-coated condoms have a two or three year shelf life, as opposed to condoms that have a five-year shelf life? Is this because the latex will deteriorate more rapidly with the spermicide on it, or does the expiration date just mean that is when the spermicide is no longer effective?
(I know spermicide-coated condoms are virtually useless anyway, but I was just curious. I have some around that expire in a year, and I was wondering why.)
Usually if a post is responded to as quickly as some others (as long as it's within the same day, at least), it means the volunteers who have been on the boards are probably just not sure of the correct answer, and we try our best to refrain from posting unless we are as certain of an answer as we can be.
I tried doing some research on the half-life of Nonoxynol-9 itself, but wasn't able to find anything, so I can't comment on the shelf-life of the spermicidal lubricant itself (though that is definitely probable).
I'd reckon, due to the nature of spermicide, it's more likely a spermicidal lubricant will break down condom latex faster than just the conditions a normally lubricated condom endures.
