In this post, 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 ?g (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 ?g. I'm guessing that there's something like 30 ?g iodine in this 72 ?g IPBC, so that's how they work out ...
