Thank you. What I’m getting from this is that there probably aren’t hidden dangers — I’ll do it and evaluate, then I’ll know whether it’s good.

For what it’s worth, I haven’t seen ethoxylates reduce foam. I read this happens for the less soluble ones (those with few EO units relative to the carbon chain length), or some of more exotic variations: branched ethoxylates, propoxylates, etc.

I’d be curious to try a really good natural potassium hand soap, but I find natural soap to be finicky. I’ve never made or encountered one I liked much, so it seems clear that it’s just plain hard to make good soap. Unlike synthetic shower gel or hand wash.

Isn’t decyl glucoside based on decanol (C10)? I don’t know whether this is universal, but I see APG0810 as the name for glucoside based on a mix of C10 and C8 alcohols, and APG0812 includes lauryl glucoside as well.

It takes at least two uses (since by definition the later use prompts a worse reaction than the former). Sensitization is the process of becoming allergic to a chemical that was previously fine. The immune system learns to recognize it and subsequently, some reaction occurs.

If someone is not sensitive but has the potential to become sensitive, it could take years, and it may depend on the manner of use. I would expect if the product penetrates the skin (for example, using it with dry cracked skin), it would be much more likely to cause sensitization.
