I recently made a soap with a couple of oz of coco butter, swirled it with coco powder, and scented it with almond and a little vanilla select. Everyone swears they smell the chocolate. The power of the mind is an amazing thing.
I can honestly say it smelled worse than anything else I've made soap with (so far). I scented mine with almond and orange. Wait till you wash with it, I was very suprised what a good soap it made!!
I left my beer in a glass overnight and then actually boiled it to remove any alcohol. I then froze it and added my lye to the beer cubes--overkill maybe, but it didn't volcano on me at all. It did smell really bad. My soap is now cured and it turned out to be a really nice soap. Your soaps...
I've used tumeric often as a colorant for swirls. I've never colored the whole soap batch with it. I also never actually use the spice, I infuse it in olive oil for several days and then strain through a coffee filter. I just use the colored oil. It gives me a smooth color and not a speckled...
I mildly scented a soap with straight up peppermint essential oil. It smelled so strong at first. It's now 4 months old, the scent is very mild, but seems to be a little stronger when the soap is wet and bubbly. No tingle or burn.
I'm lucky I guess. I have well water, it's been tested and it's very pure and 'soft'. I've used distilled too and I can't tell the difference in the soap--even the bars that are almost a year old.
