safety of lubes

There was actually a study on the safety of lubes in the rectum and how they are absorbed, and which lubes are safest, which can be found here:

Slippery Stuff is the only one considered safe for extended use in the anus and rectum.

The Slippery Stuff folks mention that Blue Label Gel does contain a small amount of parabens and acknowledge that large quantities of parabens might be a carcinogen. I'm down to injecting less than 2.5ml and don't sweat the trace of parabens I get when I'm on the road. (strictly a Shea user when at home.)

They offer a red label without the parabens. I've not tried it though so can't vouch for it's lube qualities.

The Blue label is now offered in a 1oz container suitable for carry-on luggage. If the Red label is also packaged that way, I might give it a try. Will need to order lube stuff next month so will try to retrive this thread and post results.

Thanks for the pointer. That study found Slippery Stuff safe because it is hyposmolar (doesn't pull water out of rectal cells). Unfortunately it didn't say whether its final 2 ingredients (sodium carboxylpolymethylene, methylparaben) are also safe.

Looks like there is no clear winner in water-based lubes. 🙁
