Peanut Oil in Shaving Soap. Does it Present a Risk of Allergic Reaction?

@Doc Dan recently posted a concern in the MWF "Order of the Fat" brotherhood thread (link at bottom) that the use of peanut oil in Haslingers new non-tallow soap formulation could pose a risk to those allergic to peanuts. Posting in a separate thread as a potential health risk is worthy of more attention.

For reference I've posted the ingredients for the new tallow free formula from the Maggards web site. Lots of conflicting messages on the web. Posted a link to a McGill university article on the topic that notes that those allergic shampoos and cosmetics (like hand cream) could have a skin contact allergic reaction. The National Peanut Board claims that the FDA does not consider well refined peanut oil an allergen. The McGill article does not that more highly refined products are less likely to cause an allergic reaction. Consensus seems to be that those allergic to peanuts should test a product with potential allergens to determine if it causes a reaction.

If anyone has additional information on the topic please chime in for the benefit of B&Bers for whom this may be a concern.

...on mice, in any event :p
This likely comes down to the need to test/trial any soap or cream for this and the many other ingredients that cause reactions fellow B&Bers have posted about. Earlier 2007 (link below) was inconclusive though noted anecdotal evidence of skin reactions.

Very interesting hypothesis.... Peanut allergies are nothing to sneeze at.

Sorry. I'll see myself out.....


On a serious note, allergies tend to get worse with repeated exposure....so truly DISCONTINUE use immediately if you have a reaction! Nothing to mess around with. Anaphylaxis is unpleasant to witness, and worse to have.
 
@Lane101 Thanks for posting this. You beat me to it.

I've seen people's skin and face swell after using shaving gel with peanut oil in it. I've seen people get sick after eating food cooked in peanut oil. Peanut allergies are worse than most allergies and they are never mild. Some are fatal. Peanut oil isn't all that safe. It is safer than peanuts themselves, but not entirely safe. People need to be aware of what is in their soaps.

I laughed, but in truth, peanut allergies are not hay fever. They are always serious and can be deadly.

Some might say that it is not an allergen, but knowing how serious peanut allergies always are, who would volunteer to be the test subject?
 
I just found out that Edge Shaving Gel now appears to use Sunflower Seed Oil. That replaces the peanut oil they originally used. Kudos to them.
