Is this DOS?

[Jackofhearts]

This soap I made about a month ago and I've noticed these tiny off color dots. The FO is bamboo lotus and the oil bill is:
7% castor
7% coconut
25% olive
61% lard
6% SF

I've never encountered DOS before so I don't know what to think. It smells fine but I'm obviously concerned.
I've been storing it in a very dry room that is occasionally heated with a space heater otherwise it is quite cold.
Any thoughts would be helpful. Thanks so much!

I'm wondering if it is FO rather than DOS

I'm wondering the same thing. DOS is usually more orange from what I've seen. That looks more yellow.

Ok. Cool! It is definitely yellow. I had heard that DOS could be various shades including brown. I figured if it went one direction on the spectrum it could go the other.
Also, if it was DOS wouldn't it smell off?
Thanks!

I've only had one soap develop DOS and that was a shampoo bar that was left in the shower. The spot was a brownish orange and was really soft and had an odor to it. However, I'm not a pro on DOS by any means since I've only had it once.

Not DOS. most likely FO.

DOS smells rancid. I think it somehow "eats" any other scent. It stinks! I cannot imagine that is DOS if it doesn't smell like rancid oils.

In my limited experience with DOS, it also spreads. So keep an eye on those spots, and if they get larger.......you may be dealing with DOS. But DOS definitely smells "off" so if if grows and smells bad, then I'd feel comfortable saying you've got DOS.

I agree large areas of DOS do have a stale, rancid smell to me. But if it's only a spot or two -- I guess my smeller isn't too sensitive, because I can't pick up any off odor.

Jack -- I think the yellow spots on your soap are fragrance too. I made an infused oil with annatto seeds so I could make a yellow colored soap. After making the soap, I could see tiny suspicious looking bright-orange specks on several freshly cut bars. After a much closer look, I realized the specks were small particles of the annatto seed, not DOS. Whew!

I agree with deeanna, small spots of dos don't smell rancid to me. They smell, stale, or like "old soap". Once it takes hold, it definitely starts to smell stronger of funk. I had a piece of soap sitting in water in a crummy dish for a few months that developed dos.

It can start light like that and go darker, but I also agree it's probably fo. You'll know soon enough, especially if you use it and expose it to water. The more water exposure, the faster dos spreads. So after some use, no spreading and no smell? It's definitely fo!
