corn oil, canola oil, soybean oil?

[punkflash54]

I am just curious do they add any desirable effects to the soap? are they moisturizing in soap or anything like that? They are available everywhere and pretty cheap in price so i didnt know if they would add any benefits to my soap

 

[carebear]

they do contribute to a nice mild soap, but also to the likelihood of DOS (i.e., rancidity) so whether individual or combined it's generally recommended to keep the total under 15%.

actually I've never tried corn.

I agree with Carebear, I've never used corn oil, but canola, soybean are widely considered to contibute to DOS. The only corn oil that I have seen over here is VERY yellow in colour. I believe that they colour some of it (not sure with what?) for cooking pop corn.

thanks, yeah i was just curious because i see corn, soybean and canola oil everywhere but i dont read much about it when it comes to soap making

Soy causes some people allergic reactions (one of my customers told me); canola oil is a fav amongst many soapers cuz it's cheap, but I made a few batches with it and didn't like how it had less glide across the skin than my usual fav (olive); corn oil stinks in soap (I tried a batch without added scent, to test it), or maybe it was just old.

If you want to find out properties of oils, there is a chart on our SoapMaker website. Just click on the button 'base oils' and it will bring you to it.

Why not make a few small batches with the various oils you're curious about and see for yourself? it's the best way....

I have used corn oil in the past and thought it was fine in soap but the biggest concern with all of those oils is the dos.

I would LOVE to see the chart but couldn't find it...

Requires a little work, but you look at this page to see what the fatty acids contribute: http://soapcalc.net/info/soapqualities.asp

and this chart to see the the fatty acid profiles of the various oils http://soapcalc.net/calc/OilList.asp

But rather than using the "sort" page, I prefer to use the lye calculator page to see the profiles of the individual oils and blends http://soapcalc.net/calc/SoapCalcWP.asp

(take all with a grain of salt - there seem to be some synergistic effects of certain combinations, unsaponifiables impact the soap qualities, and the level of lye discount is very important. but it's a good place to start.)

Thanks so much for posting links! Off to check em out now.

 

[leishs]

thanx for posting the links.. checking them out now.. see if i can make sense of them!

 

[jdranch]

Thanks again for posting the links. I studied the table and have a few questions. I am going to post them in a new thread!

I've tried Corn and found it made the soap yellow. No DOS yet but it is only about a month old.
I have a batch with Soy and one with Canola (small percentages) curing as we speak!

I have always used generic crisco, which is basically hydrogenated soybean oil with no DOS problems (my oldest soaps are 2 yo). I recently started using soybean oil but it's too early to tell about DOS.
