After looking over a dozen bars, I would safely guess that the ingredient list is just that...a list. In some lists it looks like some effort was made to list as for label.
When deconstructing a soap, I first write out the ingredients and then I check what conventional usage rates for the oils and butters are. Olive Oil is 100%, Coconut Oil is 15%-33%, Palm Oil is 33%, Shea Butter is 15%, Sunflower Oil is 20%. The soaps that list Sunflower Oil, omit Shea Butter.
Speaking for myself, I have two basic recipes...one for Regular Soap and one for Goat Milk Soap. Outside of the liquid, water vs goat milk soap, the difference between the recipes is that one has Cocoa Butter and the other doesn’t. I would hazard to guess that they are doing something similar.
The ‘holy trinity’ of soap making is 34% Olive Oil, 33% Coconut Oil and 33% Palm Oil. So I would start with the usage rate for Shea Butter at 15% leaving you with 85%. I think Castor Oil at 5% is important, so now we have 80%. From there, I would go with 25% each Coconut and Palm Oils, and round it out with 30% Olive Oil. Excepting the Castor Oil, these percentages match most of the bars.
