'[OT] Very thin lubricant for electric shaver'

Hi all,

I have an electric shaver that I'd like to keep lubricated. It comes with a
base station that uses small disposable cartridges filled with ethanol mixed
with some form of lubricant which is most likely polar (so that it can
dissolve in ethanol). Once this cartridge is empty, I don't want to buy
another and instead fill it up with my own liquid. I was contemplating using
isopropyl alcohol, but that alone wouldn't be enough as I'd need a polar
lubricant to mix with it.
Someone suggested glycerol, (they claimed it's used to lubricate machines in
the food industry). Can anyone verify this?

Do you guys know of any good, thin polar lubricants which are safe for skin
contact (since it's a face shaver)?

Or:

I could make something entirely non polar and use a non polar type (maybe
organic, hydrocarbon based) lubricant. Initially I made a fluid composed of
a liquid that I extracted form WD-40 (which is mineral oil, or so they
claim). It works okay, but I don't think it's very safe for skin contact on
a daily basis. Light hydrocarbons such as hexane (small chain hydrocarbons)
are too volatile and are no good as lubricants. Cooking oils tend to go
rancid, and their hydrocarbon chains are too long and make them very viscous
so they're no good in that regard either. Car oils are a no no, as they have
a good chance of being carcinogenic.

Honestly, the mineral oil that I extracted from WD-40 seems to be doing a
pretty good job, so maybe something similar will do

I don't know how safe it would be, but the first thing to come to my
mind was 3 in 1 oil.

Maybe baby oil (light mineral oil), sold in pharmacies?  The lubricant does not
have to be polar to be soluble in ethanol, btw.

It doesn't, but it will have an extremely low solubility. Hydrocarbons
(unless they have very long chains) will not be very soluble in polar
solvents. Long chain non polar hydrocarbons may be slightly soluble due to
London dispersion forces.

And baby oil is a good suggestion. I'll see if I can get some of that

Olive oil is made of Olives.
Corn oil comes from Corn
Cod liver oil ...

I dunno the name worries me.

Find out what the original is. Some plastics disintegrate in wrong oil. Apart from any effect it might have on raw skin

I'll take it to my lab and analyze it there when I get the time.

Saturated oils tend to keep a long time, so I'll try some of those. Oils
high in poly unsaturated hydrocarbon tails keep pretty well, due to being
more stable

Whoa, hang on. Are you saying that baby oil comes from ...

OMG, the trucks, the bassinet recycling warehouse, the
unusually flamboyant "Vacancy" signs on kindergartens ....

It all makes sense now. And baby powder ? You monsters
J&J, you monsters !!!!

With the amount of dust and small hairy bits a dry lubricant
might be better, eg graphite or molybdenum based. I have
some in a puffer, works wonders and doesn't clo

I initially thought that just spraying it with clippercide might work, but it sounds like this is some sort of auto-lubrication cartridge... is this correct?

LOL - can't argue with the flawless logic there. Sounds a bit like the sequel to Soylent Green :-)

Yes, cleaning (disinfecting) and lubrication cartridge

Sounds like clippercide...  not sure if that's available where you are, or if the fact it comes in aerosol will make it totally unusable - although I've found that spraying a can of aerosol into a jar or similar isn't unreasonable.

That's partly how I extracted the oil from WD 40. That, and a bit of
heating, and strong hydrochloric acid

Sorry, late to the party on this one, been on holiday, and reading my mails, this header line wasn't interesting at the time.

But, the above reminds me of a story told by a church missionary, IIRC they had been on a mission in the highlands of Papua New Guinea. Periodically they received deliveries from home, which included tinned food. The natives soon realised that the picture on the tin showed what was inside, peas, carrots, etc. Then the couple had a baby, and duly in time, received another delivery of foodstuffs from home, which now also contained tinned baby food. Only now the natives got all upset as there was a picture of a baby on the tin .... Eventually they managed to calm the natives down, pointing out that the food in the tin was for a baby, not that it contained tinned baby!
