Preservatives: Liquid Germall Plus, zignorp asks: I went to Lotioncrafter to order more liquid germall plus, and I notice that in the EU it's restricted from being used in body lotion or body cream. Do you have any idea why that is?
I contacted Jen at Lotioncrafter, and she sent me so much great information, which you'll see linked below. It seems that it to do with one ingredient in liquid Germall Plus, iodopropynyl butylcarbamate.
This is from the Scientific Committee on Cosmetic Products and Non-Food products Intended for Consumers (July 1, 2004): Considering the biological and physiological properties of iodine in potentially different populations at risk in Europe, the SCCNFP is of the opinion that the daily bioavailable intake of iodine from cosmetic products should not exceed 20% of the recommended daily intake of 150 μg (This is, for example, equivalent to approximately 0.002% IPBC in all cosmetic products at a daily use of 18 g and at a percutaneous absorption rate of 20%).
This opinion is based on the idea that IPBC contributes iodine to our bodies that can be absorbed through the skin. There's 0.4% IPBC in liquid Germall Plus. If we use 0.5 grams liquid Germall Plus in 100 grams of lotion, we would have 0.002 grams IPBC. If we used 18 grams of lotion we'd use 0.36 mg IPBC. 20% or 0.20 is absorbed, so we are at 0.072 mg or 72 μg. I'm guessing that there's something like 30 μg iodine in this 72 μg IPBC, so that's how they work out the math? (I wasn't able to find out this last bit...)
For us Canadians, the government suggests we aim for 150 μg a day, and don't go over 1100 μg a day. I think we're well within this limit with using some liquid Germall Plus now and then. The suggested intake for Americans is the same at 150 micrograms a day.
Why does the EU suggest this while North American governments don't? I have no idea, to be honest. But it doesn't mean liquid Germall Plus is bad. I see sites all the time implying that if something isn't used or allowed in the EU it's bad - I'm looking at you, Food Babe - but that's not the case. I can't bring Kinder eggs into the States, but that doesn't mean they're poisonous or deadly, and it doesn't mean that Canada doesn't care about its citizens because we sell it here. It just means there are different standards and regulations in different countries.
As a final thought...18 grams a day a normal amount of various products to use in a day? I honestly don't know. I have given this some thought and I have no idea how much I use...but I'll be keeping track for a while out of curiosity. Anyone out there have some ideas? I'm really curious about it.
