Lubricating Grease

I saw a TV show about the making of lubricating grease. The first step is making a big vat of soap out of the base stock. Then additives are added to get the properties the grease needs for a specific application.

Could biodiesel glycerin be used as a base stock for lubricating grease? Anyone here know of a small grease manufacture that you could talk to and ask a few questions?

If you make liquid soap and tone down the water used it will thicken up. I'll go on a limb here and add if you then take cornstarch and dump a bunch into the soap it will get pretty thick.

How this would fare against proper lubricating grease though is a guess. One way to find out ...

Could be a good upside, too, especially on the farm equipment: KOH glycerin "grease" is going to be way more biodegradable than standard grease.

I could see its use on old-school chain-drive manure spreaders, hay rakes, hay balers, etc. (all the old, half-functional stuff I grew up with) where you about lay the grease on with a 5gal bucket and a glove.

I don't know how well it works as a high load lubricant but they sure get a pretty penny for it when sold as biodegraidable "tire soap" or "rubber lube".

This links to Napa's house brand, $7.99/gallon, Napa's Belknap brand named "Ruglyde" version of the same thing sells for $14.49/ gallon.

This links to all the Napa versions and sizes of there veg soap lubes.

This material safety sheet for the Ruglyde says it contains Potassium vegitable oil soap plus a bit of ethylene glycol. from reading other web discussions this helps keep it from drying out.

The safety sheet for the generic version here does not list the ingerdiants, just that it is non-toxic.
