Oils causing Dos

[LauraHoosier]

I just hated to have to revamp my soap when its going over so well with friends and family although I am considering changing up the recipe after the holidays.

If I do it will be noted as a separate line for starters this way if I decide to completely switch over it won't be a surprise and most will have had a chance to use one of the "new" bars.

That's a great chart. Thank you, I needed to know a lot of what's listed there.

Just wanted to bump this thread up again because it's really useful and also to ask if there are any oils we should add to the list?

I just used Rice Bran Oil for the first time, and I am curious about everyone's experiences with it. David Fisher on candleandsoap.about.com said he has heard it is prone to DOS, but he has personally not experienced it when he's used it.

I use RB at 10% and haven't had any issues.

Oil freshness is more critical than amount, I believe. I buy small amounts of high-lino oils from reliable high-turnover dealers, add ROE, store in fridge and use them quickly.

I posted recently about a soap I made 11-12 years ago with grapeseed as first oil, and there's no DOS in it, even now.

10% Sunflower will contribute .1% of vitamin E which is enough to provide anti oxidation protection. Combined with the BHA and BHT in packaged lard would seem to have the properties of a stable bar.

I have used 35% rice bran oil and 6% superfat in one of my soaps. It is almost 9 months old and no signs of DOS/rancidity. No preservatives, but with 0.5% GSE.

I have used RBO at about 25% and haven't had any problems with DOS.

I use alot of soy in my soaps, my favorite soap is 40% soybean although hydrogenated. I have soaps that were both colors and white, and no DOS. However... what I did notice, is if you put soybean oil or crisco in soapcalc the linoleic is very high, but hydrogenated soybean oil is very low, and thats what I use. There is a big difference between crisco and hydr. soybean as crisco adds rapeseed and or cottonseed. I get mine from soapers choice.
