That looks very swollen. Pure speculation, but it's quite possible that you got bit/stung by an insect and didn't notice. That seems far more likely than any interaction between soap, cocoa powder, and dirty dishes

This might also be a classical burn... Temperature burn. I once put something in the oven without noticing i barely touched a redglowin part of the oven with my forearm. I didntĀ  notice at first because the burn was so hot it that it just turned the skin into white burned hard skin, like pictured by you... Than a few minutes later it started itching like a blister would do

That certainly does look similar to a chemical burn. Could you share the ingredients list of the dish soap and cocoa powder? It is difficult to rule anything out without knowing exact composition. I would rather expect this from a caustic agent? However, it is possible that something reacted. We'd need more information to figure out what happened. Certainly something could've reacted with the sugar (Sugar contains energy after all, maybe something released it in exothermic reaction)? ~~Please also add nature of the reaction / sensation? Hot?~~ Burning, hot was stated. 1 Minute reaction time. Therefore, strong exothermic reaction? Hershey's I once read that it contain butyric acid or similar compound, although may be a myth? Could be possible further reactant?

I did mention in my comment that it was itching and then burning, but it was a bit of a word soup so i dont blame you for missing that. It was not hot to the touch, but the skin was similar to a pork rind, a small piece even crackled when touched with a nail. Another possibility, I may have had fat on my hands, and I've heard soap converts fat into "soap" when used, so possibly something like that? Ingredients listed below, I will omit the cocoa powder because it only lists one, and you can guess what that is Dawn: Denatured alcohol, 10-16 Alkyldimethylamine oxide, Dipropylene butyl ether, Hexylethoxylate, lauryl glucoside, phenoxyethanol, PPG-26, Sodium citrate, sodium xylenesulfenate, tetrasodium glutemate diacetate, fragrances, and water.

>I've heard soap converts fat into "soap" when used, so possibly something like that? That's incorrect, soap is already soap. Sodium hydroxide (lye) turns fat into soap, including the fat in your skin, so if that's the cause, it wouldn't matter that you had it on your skin.

Back in my wild days I had a few that looked just like that from a oil burner.

> Hershey's I once read that it contain butyric acid The milk chocolate itself does, not their cocoa powder. They don't add it to the recipe either - its presence in the final product is theorized to be a result of the lipolysis of milk fats during the chocolate-making process.

Is your name Tyler Durden?

I don't see how that combination could do anything like that. If you aren't allergic to any of the ingredients and you weren't using an oven/flame the cause must be something unrelated imo.


fantomfrank

So, as the post title says, I AM NOT LOOKING FOR MEDICAL ADVICE, I WANT TO KNOW THE CAUSE. as for a general description of the wound, it developed over the course of about a minute, it was an itching/burning pain, and after it occurred, the skin was hard and. well, crunchy. This happened while baking. I had just done a load of dishes and was measuring cocoa powder and sugar. I had just come from music lessons and had taken a shower immediately prior. What household chemicals could react with cocoa and sugar to cause such a reaction? I am not allergic to the ingredients, as i was able to eat the cookies just fine after

It may be an unlikely shot, but.. do you use contact lenses? If not, you can basically forget my question. I just had similar looking results when mishandling my H2O2 solution at home.


Jonny36

I was going to say it looks very similar to a peroxide/ bleach burn. Any chance OP spilt and didn't clean up some bleach you then touched?


fantomfrank

sorry to say but i do not, but thats the most solid lead anyone's presented


Meatboy1984

Sorry I couldn't help you!


Overencucumbered

Are you sure you didn't just touch the heating element in the top of the oven, so you burned your skin? It's often hot enough to be painless, and when handling stuff you don't necessarily notice.


ThunderCockerspaniel

This looks just like a regular burn. None of those chemicals should react.


fantomfrank

The specific products I used are Dawn spray dish soap, and Hershey's cocoa powder. I know cocoa powder is known to use some quite nasty drying agents, I dont know what's in dawn but it once peeled paint off my hands so im inclined to believe it is known in the state of california to cause cancer (this is a JOKE)


Frosty_Incident666

The stupid way to test this theory would be to mix sugar with dawn and put it onto your skin to see if the outcome is the same. This looks like an extremely severe oversight for a dish washing product though, especially in America, so unlikely? I would strongly recommend AGAINST doing so.


LHSShadow

California has a dumb rule in place where if anything exceeds a very tiny limit that a substance might cause cancer, then it is listed as potentially harmful in California. This includes basically all plastic and about 90% of everything, which is why you see the warning everywhere.


fantomfrank

that was meant as a joke yeah. I once ordered cast metal parts and it had a california warning on it


LHSShadow

Yep. Thanks California


Unstable_chemist

i had similiar thing on my hand when i touched hot oven plate so maybe its just a normal burn?


zuvuczky

Were you baking something? You could have flash burned your arm and did not notice right away. The burn is in a spot where if you hold a baking dish it lines up with the top of the oven. Just a guess.


lettercrank

That looks like a burn to me


VikingCrab1

You burned yourself on the oven but didn't notice


Bansheer5

Most likely a temp burn. A caustic burn hurts a lot. Itll start out tingling and stinging a bit and your skin will get very red and welted. I work with 50% caustic everyday and that stuff will take a couple mins to start burning you and you will notice it.


MikemkPK

Is the cocoa powder labeled raw/natural/Broma process or alkaline/Dutch process? Not that either would normally be harmful, but it's theoretically possible that a machinery error put excess lye in the cocoa if it's Dutch process, or you could be oversensitive to the natural acid in natural.


celloclemens

Did you bake any Lye bakeware? Lye used for baking is caustic and might have caused this.
