For chronic urticaria Is "technical grade" glycerine safe to use in a skin cream to stop the itching?

Question

I am making a cream using a recipe recommended on the International Chronic Urticaria Society's website.
The recipe is:
2 tsp glycerine
1/2 Cup Eucerin
1 bottle nasalcrom.

None of the big drug store chains seem to sell it anymore. I found a company called The Science Company and bought a bottle. I did not know that there were different grades until the bottle was delivered and the label warned that the product was not for household use

Answer 1

I would recommend you to consult with your dermatologist first, good luck
