i forgot, where are you located? i think castor is quite easy to get, but def not in supermarkets. check out the chemical stores, ask for minyak biji jarak. usually around Rp. 50K/L.
Pomace OO, hmmm... if you know where to look, you can def get it less than $10/L
you gotta buy in 5L jugs though. i've seen one in a supermarket for Rp. 85K/L. i only use pomace, as pure olive is def far too bloody expensive.
i think you are not listening to the good advices others have given you so far... that is to learn to use
lye calculator. a very easy one is from brambleberry.com (look for
lye calculator on the left hand side options). it is seriously the most straight forward calculator. by using a lye calc, you are saving yourself from creating a dangerous soap like shown in the above recipe (far too much lye). please please do not do that recipe, it is seriously dangerous.
2nd of all, you cannot use that much coconut oil w/o at least a 15% superfat (SF). otherwise, the soap is going to be far too drying. also, i don't see a point using castor if you already using that much coconut.
you are better off adding another oil or 2 to the bunch, like palm and a bit of OO or soybean or canola.
i would do something economical like:
50% palm
30% coconut
5% castor
15% soybean or canola
6% SF
CDEA, i did a quick google search and so far i cannot found its SAP value, therefore it should not be added to the lye calculation. it should be treated as an additive. it's a foaming booster as far as i know. personally, i think you don't need it, with 30% coconut + 5% castor, your bubble level is already 25, which is not bad at all.
also, scratch the sodium silicate if you don't even know what it's for. waste of money me thinks.
papaya extract, please contact the manufacturer for usage guide. is your extract powdered, water, or glycerine based? you have to find out about this first. read the ingredients, if it contains alcohol it can mess up with the soap if done CP. you might wanna do HP instead.
fragrance, again, each fragrance has its own usage guide, but generally, around 3-6% from total oils.
if you have some free time, please read this link below, it will give you a general knowledge on different oils and their characteristics:
