...and tribulations! lol So, I have family who is allergic to almost everything, including the regular type of dishwashing liquid. I used a recipe from Arianne, since this person is also allergic to Coco Betaine, which is in the recipe from Humblebee. Here's the recipe. 550 grams of Sodium Cocoyl Isethionate (SCI) 148 grams of distilled water 48 grams of white vinegar 65 grams of sodium carbonate 5 grams lemon essential oil Since I was experimenting - first time and all - I used an older Lemon Unhinged from Mad Oils instead of buying yet another EO. Everything went fine, it came together easily, even if it did take an eternity! lol I put most in a container for my personal testing and a little bit (2 oz) in another container with a lid. Tried it, like it, seems to do fairly well. Noticed that the next day (or the day after) it turned brownish. Checked the untouched 2 oz package - it was brownish also. Not evenly brown, just rather mottled. My first thought was mold, but it still smells fresh and wonderfully lemony, even after a week of looking like this. Is this just from the FO? Mold? No preservative in the recipe, you'll notice.. Thanks for all you do for me! I appreciate all the help and inspiration I get here!
