Virg,
(is that short for Virgo?) rib rib, I have a lot of Virgo in my astro chart, we tend to be the health conscious (or freaks) of the world. 😀
In doing a bit more research, I would say Probe does appear to be the safer of the commercial water-based lubes. I've not ever tried, but look to give it a whirl. K-Y never worked well for me and in researching it contains that darn benzoic acid.
I thought you might find the following site of interest:
http://www.cosmeticsdatabase.com/browse.php?category=lubricant/spermicide
Their site was down over the weekend for maintenance, so I couldn't access earlier. (Probe gets high marks). This database is by no means comprehensive, but does give quite a bit of info.
I want to dig into this research a bit more as well. I think the healthy oils would definitely be the best route. Coconut has good fats actually. Olive would be good.
Propylene glycol by the way is used in antifreeze. What form are they using in lubricants? Cosmetics and lubricants are not regulated by the FDA. And from my own experience, I would be reluctant to use any soy or soy-based/mixed oil. Soy is not a health food and actually is a known thyroid and endocrine system disruptor. My 2 cents.
Following suggestions by others, I have been looking into the use of oilive oil and coconut oil as safe internal lubes.
There is a very large amount of info on the web about the benefits of both coconut and olive oil. For some, they are miracle substances!
Again, back to the REAL issues for use in the Aneros world...
The coconut and olive oil is ingested and processed in the stomach. It is broken down and absorbed.
For us Aneros users, it is not broken down or metabolized. It is just taken into the bloosstream without being "processed". So, given that, can one trust the glowing testiminials apply to these oils for Aneros use? I do not know. It may be that either "path" to the blodstream may not matter. Then again, maybe the chemical reactions in the stomach are critical for these oils to be broken down to a "size"(?) that they can enter the bloodstream and be beneficial. Maybe, via the rectum, these oils are not beneifical and are "boulder" sized compared to their "size" when metabolized via the stomach.
Unfortunately, there just is not any facts or research that I can find on these kind of questions
Again, in the Aneros world, almost all assumptions do not apply, or, at least, need to be reconsidered.
All that said, I feel better about using all-natural, organic fluids that the commercial "personal lubricants"...
Just some things to consider and be aware of...
Bump ... with comment.
While the information here is "old" there are many gems of wisdom and experience to be considered. However, in the last eight years we have some more knowledge available.
Some observations:
About rectal absorption versus absorption further up the G.I. tract: Fluids in the rectum are absorbed and picked up by the Portal Vein where they are carried directly to the liver ( https://en.wikipedia.org/wiki/Hepatic_portal_vein ). This is the fast-bypass path that chemicals in the vaunted Coffee Enema employ to quickly reach the liver for a periodic 'cleansing'. Consider which undigested chemicals you care to send directly to your own liver.
About the various parabens:
Some years ago I was certified as an industrial inspector of petroleum storage and dispensing systems. While I always wore taped boots and gloves as well as a breathing device there was always the hazard of absorbing petrochemicals through skin contact, clothing contamination or contamination in the breathing device.
I was taught to be alert for diabetic-like tingling of my skin, particularly my fingers, as an indicator that bad stuff might have entered my bloodstream..
Imagine my surprise several years ago when I used a popular anal lube (not made in this country) and after an hour-long session felt "mentally dull" with tingling fingertips. Sure nuf. Both Glycol and Propyl Paraben were in the list of ingredients. Considering how many hours a week I'm exposed to lubes I've chosen to use water based lubes only during travel and choose from a short list of those containing no Glycerin and very little Paraben.

Organic expeller pressed virgin coconut oil with a bit of shea butter mixed in. All natural. The clear choice in my opinion. Heat 20% shea to 80% coconut oil in a glass jar in the oven on a very low temp to liquify. Make sure its not too hot before using! Just my 2 cents. I fall back on ky but try to minimize use of it.
