I'm still new to CP soapmaking but I'll throw my 2 cents out here anyway..
I'm not sure beeswax can be used at such a high rate (I don't know how much palm you use in your recipes but I usually use it between 20 and 30%). I have a friend who keeps bees and he keeps giving me large amounts of beeswax, so I incorporate it 2-4% in my recipes to keep from getting ash and to make a bit of a firmer bar when I use a lot of soft oils.
I usually just throw it in with my hard oils to melt it in. I have had great results so far with my method. I'm sure soapbuddy will be along shortly to have a solid answer for you!
