I definitely agree with Navaria. Your cleansing number is too high. I think I noted on earlier posts that you were mature in your years; (me too). An emergency total hysterectomy instantly caused total hormone changes resulting in totally dry skin. If it were me, I would try to keep the cleansing number under 10. Personally I won't go higher than 8 and I use coconut milk sub to add additional SF.
PKO flakes are awesome, but combined with your coconut oil, that is what is causing your high cleansing nos. I also agree about the castor. If this is one of your first batches, I would recommend keeping it at 5%. Also if you want your mango seed butter to "count" - up to a minimum to 10%. How about adding some avocado oil or cheaper, some sunflower oil? - Easy to get, great for the skin. If your soap starts to get too soft, you can also add 3-5% beeswax, or crunchy version of candelia wax. Waxes are an easy way to add shine and hardness to your bars.
Finally - Though 1 lb batches are more economical, 2 lbs are better. - A little more forgiving if you don't measure out exactly in grams; slightly larger batches give you more working time Your current recipe will be more fluid, but once you start adding EO/FO and color, smaller batches are less forgiving and harder to save.
Okay, really finally.... As you continue to play around with recipes.....(become completely addicted) always save a bar of soap from your batches. a). It will help chronicle your soaping journey, b). Help identify problems - DOS, fading scent, color changes, etc - even if you don't plan to sell, you will eventually need to give some away. (the addictive factor is that great). Good luck - remember to post pics!
