Thank you,
Penelope. I certainly do believe that certain things are definitely absorbed through the skin, after all there are plenty of topical medications that work quite effectively to treat certain diseases. And regulations have changed many times in my lifetime regarding OTC products that are topically applied for that very reason. And of course we all do have different levels of sensitivity to different types of things regardless of regulations. I, for example, can't use almost any commercially prepared hair conditioner on my hair without breaking out in unsightly and extremely itchy raised red blotches on my face and neck. Most people I know think that's really strange. But it is what it is and I just don't use hair conditioner and I'm fine most of the time.
I suppose that even with the IOC regulations that restrict the allowable amount of benzopyrenes in pomace olive oil it may still be a problem for someone with sensitivities. Benzopyrenes are apparently what is restricted in pomace olive oil in the European Union and members of the IOC (
reference). In the USA, however, it appears that what is restricted in pomace olive oil is halogenated solvents, heavy metals and pesticide residues (
USA reference). I don't really know how those compare to the European restrictions, though. And I don't really know if the imported pomace olive oil that I buy meets USA olive oil standards. I am guessing that it meets both European and USA standards, but of course I cannot be sure. For me I think it's okay. Additionally, I investigated around a bit to read about regulated hexane exposure limits in the USA at least, since that's where I live. I found
this and it leads me to believe that for me anyway, using pomace olive oil in soap is not going to create the kinds of exposures the CDC (Center for Disease Control) is concerned about. I couldn't find sufficient information from the WHO on hexane to address this topic; maybe I didn't delve deeply enough into the WHO articles, though.
But I thank you for sharing your concerns and now I better understand them, I think. And as a result of this conversation I did delve a little more deeply into the subject than I had previously, so that's always a good thing. Keeping educated is always good, IMO.
