I was at the farmers market this morning and noticed a soap vendor so I checked out his stall and noticed he was selling soap covered in DOS. Oh the horror of it! I'm brand new to soaping (3 batches) and know better.
 
Are you sure it was DOS? Sorry... not to question your judgement, but you do say that you are brand new to soaping. There were a few times early in my soap life that I mistook fragrance morphing for DOS.

I'm pretty sure it was DOS. It looked spoiled.
 
Also, if they added in Herbs or such it can look like DOS.
I had that on a soap that I knew couldn't be DOS because it was under a month old.

DOS doesn't really bother me, but I wouldn't sell it. lol

Were ALL the soaps like that ?

The vendor said it was sage soap so maybe there were herbs in it. Whatever it was, it looked like spoiled soap and something that shouldn't be sold. I don't even give mine away yet because they're not perfect. In the interim I'm researching like crazy. Hopefully I'll get there soon...
 
A fairly sure test is to smell it ... DOS tends to be accompanied by a distinctive rancid or "dusty" smell.

Some other things that mimic DOS are unevenly dispersed colourants (turmeric does a really good imitation, with paprika able to make dos-like halos if the grind size is too big).

Then there's honey, carrots, pumpkin (ok, anything with carotene can mimic dos) ...

Sometimes there can be a reaction that isn't dos (I've been able to get a weird reaction with some colours that were never meant for soap, and they have gone an almost perfect dos colour, without the rancidity ... they are still soap without deformation after a year now, and no ugly smell).

That's another giveaway for DOS - it usually warps as well as smelling bad.

After all of that, you could be right too. :D

Some market soapers here have shown up with soap that I wouldn't dream of applying to my skin. Luckily our market is fairly savage on mediocre sellers, so they don't usually get to come back - the only time I've seen one back was the same person, but with a different product. They failed at that too and so, after two goes, vanished entirely.

Sage (and most botanicals) will turn brown after a while, especially if they are out in the sun. Sage doesn't completely turn (from memory, it's been a while since I put some in), so you could get an odd (very slight) greenish grey tinge to the brown ... if you saw a soap with flecks like that it could look like dos.

If the botanical isn't completely dry and is a bit too large, it can go off in CP soap.
You need to deliberately cause a soap to get dos, so you can smell and look at it :)
(You can do this by dipping a newly made bar of soap in rancid oil ... that's about the quickest method - the soap will soak in the oil and that will trigger dos. Alternatively cure the soap on something copper or brass - those metals do the same thing, trigger dos).

Happy DOSing :rolling: (sorry, new smiley, had to use it)
 
Usually a very dossy soap will smell very off and be somewhat sticky. Even UV rays can change the look of soap, it could be a green that faded to yellow in blotches. I sell at outdoor markets and the UV rays are brutal on soaps. Many times an older soap will be 4 times different in color than under the label.
 
Agreement with all of this. I make a patchouli mint soap and add a mint tea mix into the soap. In its early days it looks very much like cheese gone bad, but after a few months it looks quite lovely - if you like a simpler looking, herby type of soap. I got a bar of soap from a soapy friend last year, and finally pulled it out of the box to use earlier this year. (I am not a good friend and have too much soap in my personal stash to use all of it in a timely manner.) It had weird brown spots on the bar, that at first glance I thought were DOS. I did a deeper analysis - smelling, and digging my finger into the spots - and I don't know what it was, but I'm 100% sure it wasn't DOS. My friend no longer had bars to compare with, and I did feel "safe" using it, so I did. The brown spots were consistent through the soap. The only thing we could come up with was that the soap was white with colored "gumball" embeds. The brown spots were consistent around certain colors, so we suspect that something between the color she used for blue and red did not play well with either the soap process, the FO, or possibly aged poorly. (She's doing her own experiments to see if she can nail it down.) Anyways, sometimes what looks like DOS, isn't - and even experienced soapers may not be able to tell what it is for sure when it isn't DOS.

While the sage soap didn't appeal to you, that soaper may have clients that it does appeal to. That's ok. One of the great things about making your own soap is that you get to make what you like and not have to worry about what appeals to others. (At least, until you start selling... then all that goes to heck and you have to make tons of lavender soap that stinks up your house and you can't stand it.)
 
lol Lavender...No one who hasn't used it would believe you could not like it. EEK! I really like lavender but not when I am making anything with it.
 
Last craft fair I went to had a soaper selling DOS soap. All her soap was spotty, greasy and stunk but the lavender was the worse. It was the grossest display I ever saw.
Other people didn't know what it was but the smell was detering them. I didn't see anyone buy her soap but the other two soap booths were selling.
 
Mahogany from BB for me morphs into a suspiciously dos'y looking color (not to mention it did actually dos in some batches). Lemongrass looks like DOS after six months if I don't color it...it could've been the colorants. The smell would be the giveaway. Lavender and I are not friends because so far they ALL dos!

Lavander gave my soap dos when I started making my own soap several years back. I don't use it anymore in soap, I use it for leave on products only.

Ding ding ding....we have a winner! Just went back to the stall. You're right, its fresh herbs that discolored.
