Why can't you use Fryer Fats?

[Lucky7s]

What would happen if you used old fryer fat?

Like from a donut shop? Why do you have to use olive oil and coconut oil? Isn't that expensive? Why not just use fryer fat? Is there a way to filter it first?

Has anyone tried it? Would it smell bad? What if it was from a donut shop then would it smell good? :?: :?:

Just trying to save a few bucks.

I'm gonna go ahead & guess that it would be extremely unsanitary to do that.

People have done it. Look around the forum, do a few google searches. You will find info. I know there is a thread here where they used old bacon grease, and maybe another with hamburger/french fry grease.

I feel an "ick" factor about it myself. I'd probably do it if I were dirt poor (which could be any day now) and desperate.

Buying soaping ingredients are making me poor too. :wink:

I have an "ick" factor over using recycled oil as well but give it a go, for sure.

I think it would be a lot like rendering lard or tallow down - same amount of effort and you end up with a nice product. I don't have the time to do the rendering but I trully admire people who do the work, because there is a lot of it. Talk about returning to your roots, people in the 30s recycled their fats all the time...

I think it'll be DOS prone.
And if it's from a shop how will you know it's not contaminated with nasty stuff and the stuff used to clean out the fryer, etc.
But hey, I'd clean my floors with it.

Use it to run your generator, or to clean your garage floor, but not on your body.

I want togo on record as saying my post was not in support of using waste grease, it was in support of using the search function :wink: .

 

[babytinkie]

Waste grease was what was used by some people back in the day. When I first started researching homemade soap, I ran across a few articles about cleaning waste oils and grease. It seemed like a messy, smelly job to me, but some people do it.
If I remember correctly, you have to mix the oil/grease with water and boil it several times. I'd rather spend the money than the time and mess of cleaning.

The reason I started making soap is because it was a luxury. It feels wonderful, smells great, is an experience. I want it to feel like biting into a delicious chocolate.
Not like biting into a greasy fast food bacon cheeseburger. It just feels gross, and you know you'll feel gross later, too. That's what I imagine when I think of waste oils.

Is it possible? Yeah I'm sure it is! It will probably smell different, yeah.

jmo and to each their own!

Also, be warned, this is an expensive hobby! You can cut corners but no matter what you do you will end up spending money (more than you intend ...) on this addicting hobby.

It is my understanding that early soapers used whatever oils they could get their hands on. I see no problem with using waste grease, especially if its from a donut shop. I'm sure they can let you know what kind of oil it is. I mean, what the heck, try it...if its really bad, then chalk one up to experience.

Here's why NOT:

Oils used in cooking, are generally used at high heats ie: donuts...deep fryers, bacon...grills. They are heated to 350 degrees plus. Any oil raised to that temp will go rancid quicker than the 'virgin' oils that we use in soap. We monitor the temps only bringing the solid fats to a liquid form, anywhere from 140 - 170 in most cases.

You may pick up these oils for less than nothing but if your soap goes rancid right away, you're losing not only your time spent on clarifying the oils, but your time making the soap and now you're tossing all your efforts in the garbage because it is gross and unusable.

Sometimes 'FREE' bites you in the a_ _. :cry:

People did a lot of things out of need & deperation that we do not need to do today.

They also used the soap up quickly. It did not sit on shelves or get sold at craft shows to be tucked away and pulled out a year or 2 later after DOS has set in & oild have gone rancid as sigrid mentioned above.

You would have to know what kind of oil it is so you know the SAP value. I certainly wouldn't soap it 100% if it was some sort of veggie oil. JMO

I second that...

I mean you could use it, But in order for it to be really good for use youd need to "clean" it with chemicals...which kinda adds waaaaaaaaaaaay more work, and chemicals to the whole natural soap shebang....

making soap

I want to make cold hard cash producing soap. Making it with olive oil or pomace oil isn't gonna make it possible.

Lye is cheap. 100% organic additives are cheap for me, like mint, powdered walnut shells, and the like. The oil is the part that will kill me. How can I refine glycerin? The smells that are left over are the hard part. French Fry etc...

How can I clean the oil after it comes out of donut fryer? Boil it with water? Filter it? How can I get the smells out. Centrifuge? I'm talking about making 10,000 bars at a time and wholesaling them for a 1$ a piece. No ammonium laurel sulfate for me, 100% recycled, etc.....

Should I just make floor soap instead of body soap? I want to make body soap.

What makes soap go rancid?

They do it in Japan to go green.

One group sprinkles flour over the oil, and as it settles to the bottom, it takes the sediment with it. To me, that doesn't seem like it would work well. Another group boils the oil 1 to 1 with water. Let it separate and boil one more time, again with water. (All this boiling after letting the oil filter thru folded cloth to get any chunks out.)

To me, its too much work to play around with, but if you are serious, it can be done. I think Id let the bio deisel people have the used oil, and let the people who want $1 soap buy commercial.

Agree. You may want to slow down and do some more research and study on soapmaking/chemistry, et.c, before deciding what it is you want to do and how to do it.
