I'll update this post as I test. CORNSTARCH: I don't notice any effect from the cornstarch. The soap bubbled and lathered just like a good little soap should. There was no dryness and left my skin feeling moisturized. I do have to say that I may have to look into OT FO's. I loved the Frosted Wineberry and have heard some other good things lately. MAYO: This little bar made my skin feel great. I don't know what it was about Mayo but it worked. AVACADO: SOUR CREAM: EGG YOLK: YOGURT: This bar went from bubbles to lather in under a second. Nice feel on the skin. I like this additive. CARROT PUREE: Wow, did this ever bubble. Again there was no dryness, this was a nice soap. CUCUMBER: I was a little worried about the yellow dots. I've never seen DOS (knock on wood) but I just figured it was the cucumber (I hope) Anyway, I thought the bubbles onthe carrot were wonderful...the lather on this bar, wow. It didn't take any work to get the lather started, just rubbed the bar and tons of lather. The scent was very light but nice. It was a good soap but I didn't like the yellow spots.
