Does anyone know of any specific allergic reactions to any reloading components - particularly contact dermatitis and powder?

Thank you

Never is over 40 years of reloading.

i haven't seen it.. but anything is possible, i suppose

my skin was itchy when I tried to clean the cases - especially the primer hole...

Now I put all in a Ultrasonic bath and they are clean like new - and no contact problems with primer dust anymore...

I stopped reloading because I became allergic to the solvents in the powders. Just breathing the fumes not contact.
If it's just contact you can use gloves [different glove material will handle different chemicals].
Experiment to find exactly what you are allergic to ,then proceed from there.

You can be allergic to almost anything and the reaction can be almost anything !! The medical "profession" has been reluctant to admit that small molecules can cause a reaction as the definition only accepted large molecules like protein . The finally found that small molecules like chemicals combine in the body with large molecules and that causes a reaction. This isn't even called allergy .They call it MCS [multiple chemical sensitivity].You can PM me if you have other questions about it.

There is so little occasion for powder to contact the skin that I'm surprised that this question has arisen.

Fumes from the solvents are another thing entirely. Luckily, I have no sensitvity to solvent fumes, but inhaling the chemical carrier in many perfumes will prompt an asthsma-like reaction in me. Besides that, the perfumes usually have an unpleasant odor about them in the first place. Hand lotions, cologne, scented detergents, and laundry sheets all disgust me, and some of them make me wheeze.

I developed white spots on hands, doctor thinks it may be caused by Hornady's One Shot gun cleaner which I use to clean and lube my dies

Iam alergic to loaded ammo, i dont keep it around very long. itchy trigger finger

I am trying to track down possible causes of idiopathic hyperkeratosis and sloughing that recurs episodically and I know this was was long shot but there are no explanations for this phenomenon.

Thank you for your responses.

Oxon,
Where does this hyperkeratosis and sloughing occur?
You can answer by PM.
There are some issues that I have looked at.

I have seen it on the palms and on the soles of the feet. There are known palmo-plantar dermatologic diseases but most are genetic and non-sloughing.

Just a long shot but there is no medical explanation, yet it happens. It's very rare and most often just goes away but in two instances it has occurred in men in contact with loading materials.

Handle some while wearing nitrile . . . NITRILE gloves and see if you have issues.

Few more (actually a bunch) details about conditions that cause the issue.

Good one!

Wear gloves when using degreasers and cleaners that remove the oils from the skin. That kind of 'break-out' is not allergy, to me, but simply a response to loosing the oils the skin needs.
Being a chemist, I don't have reactions to any chemicals, but I do have reactions to environmental factors.
I have no idea how one can become sensitive to the solvents in the powder, since most powders have almost zero solvent left in them (my old bottle of PB powder, however, reeked of MEK). It just shows that some are very sensitive.

I suspect your "environmental factors" are indeed chemicals.

Allergies or acquired sensitivity is not restricted to solvents. Indeed, there are dermatologic responses to metal such as nickel.
