Have you zap-tested the soaps? That's a much more reliable indicator of whether or not a soap is safe to use. A soap can have as high of a pH of 12.35 and still be safe (Jonson's Baby Oat soap has a pH 12.35 for example according to a test carried out by a dermatologic study and mentioned in the book, 'Scientific Soapmaking').
Unlike a pH test, a zap test will immediately tell you if your soap has any unreacted lye in it.
For what it's worth, here's the color chart that I have in my notes in regards to the Red Cabbage Juice test:
pH 1-2 pink (acid)
pH 3-4 dark red (acid)
pH 5-6 violet (acid)
pH 7-8 Blue (neutral to base)
pH 9-10 blue-green (base)
pH 11-12 greenish yellow (base)
Since lye-based soap is alkaline, it will always test out on the alkaline side of the pH scale (most soaps fall somewhere between 9 and 11.5), which with the cabbage test can show up as blue or green or any combination two, with maybe even a little yellow thrown in at times. While the test is good for telling you whether a substance is an acid or a base, it really won't tell you if your soap is safe to use. At most, it will tell your soap is alkaline, but that's something we already know since lye-based soap by definition is an alkali salt of a fatty acid.
This is not directed against you, MM, please don't take it that way. I just never understand why people don't zap test for safety. It is so easy, free, and much more idiot-proof (tested against me!) than anything else ...
Just might get me thinking, maybe a garlic tomato soapie . Think it will scare away this HOT weather we are having. Sorry a little detour from the original post. It was your fault Obsidian you brought up soaping with cabbage :crazy:
