welp, I finally experienced Castile slime. I recently made four nearly identical recipes of Castile. No coconut. Scent was used, different for each but at 3%. SF 0%. In each recipe the exact same oil was used. Currently we’re about 2-3 weeks in with most of them. In the first, it was a one pound recipe, two color, no water discount. I did use a mixture of lyes, both NaOH and KOH. This one has good lather, good scent retention, solid bar. No slime. Second, three colors, and a pencil line of AC. Same oil. Mixture of NaOH and KOH. CPOP. Scent is good. Good lather, glycerin rivers, but ready to be used faster than the others. 3rd two colors and one section uncolored, swirl. NaOH and half the amount of KOH of the previous batch. Strawberry scented and mouse approved. (Ugh). Tested it today. As soon as it got wet, it became a goo ball, a slime beast, so nasty to touch. Soap snot cling to my hands, made long strings and nasty. So gross. I will continue to test it for the next six months and see what happens. Fourth. All NaOH. Same oil. CPOP no color (tried a lw/hw design and failed miserably still made soap) FO. Here’s the interesting thing, no slime. Solid bar of soap, good lather. I do soap at really low temps, and I wonder if some of the slime is due to temp and not just NaOH. Both CPOP batches are about the same, even though one has just NaOH in it. I did note that in the epic Castile super lye post from several years ago, that one of the soapers notes that she hated the slime ropes in her Castile. She lives in the pnw. I live in the pnw. The pnw is famous for colder temps and high humidity. It rains a lot, is damp and it rains. Did I mention it rains? Like a constant drizzle. I personally have super lyed my previous Castile batches and added a bit of coconut, ahhhh bastile... and love that soap. I think there may be a few ways to combat slime. Change the formula a wee bit - The addition of oils like coconut, babassu, etc. changes things enough for a better soap to deal with. Use a combo of lyes - KOH brings a different property, but don’t use less than 5%. Heat. Castile soap is usually cooked for a while or HP and may do something to getting rid of slime. Either way, that slime is somewhat horrid, and I’m amazed that I have avoided it until now.
