Is there a reason it can only be used in certain concentrations? Fascinating!

Amy, that’s because red 33 is one of those dyes that can contain small amounts of lead. However, if used in concentrations up to 3%, the concentrations of lead are so minuscule that lead won’t pose a threat to human health as our body will just get rid of it.

Marguerite, grazie. Sono contenta che trovi questi post utili.
Do you know if red dye 33 contains iodine? I recently had abdominal surgery and my skin is really dry cause of the tape on the bandages and itched so much I was using hydrocortisone cream. Well that dried my skin more so I was using Johnson’s Baby lotion. Well, my skin is still dry after repeated uses and itches for awhile after I apply it. I am allergic to iodine so Im wondering if iodine is in the dye? Ive looked all over online but cant get any answers. Thanks so much!!
Kris, I did a search but unfortunately I couldn’t find any information about it. I am personally inclined to believe it doesn’t because it would have been mentioned somewhere if it did, but I could be wrong. I’m sorry I couldn’t be of more help and I hope you get better soon.
Thanks for trying! My surgery was 2 wks ago yesterday so Im doing pretty well. More healing to do inside but the incisions look great. (I had a laparoscopic removal of my ovaries so I have 3 small incisions and one a few inches long)
Kris, you’re welcome. That sounds awful but I’m glad you’re doing better and I wish you a speedy recovery!
