Please check... 4-oil recipe!

Hi every buddy!

My son and I have been practising We have made 1-, 2- and 3-oil soaps and now that we have some palm kernel oil, we'd like to attempt a 4-oil soap. This is our proposed recipe (soapcalc doc attached):

Olive oil (EVOO) - 60%
Coconut oil - 20%
Palm kernel oil - 15%
Castor oil - 5%

I have not had much luck with olive oil in large quantities and sometimes miss out important recipe details, so I'd appreciate it if you could give this a look-see and let me know if it needs tweaking or if I've missed anything?

Additional questions:
1. This looks like it will be a decently hard soap, yes? So I'll have no need for sodium lactate, am I right? I used it for a Castile soap, but since this has CO and PKO, am I right to assume that there is no need?
2. I had used bottled water before [we have hard water here] and 1 or 2 of our CO soaps had spots which we think were DOS. We are using distlled water for this soap to be safe... should we consider citric acid or not?

Thanks so much!

Palm kernel oil and just palm oil are two different types of oils with a different fatty acid profile. Palm kernel oil is sometimes used as a substitute for coconut oil in recipes because it contributes to the cleansing capabilities of a recipe. To combine Palm kernel oil with coconut oil in those quantities could make a very cleansing soap which many would find too harsh/drying. Try using a combined amount of the two of no more than 25% and make up the difference with OO.

Sodium lactate doesn't really make the soap any harder - it just makes it easier to unmold. I ran out about a year ago so I stopped using it, and to be honest I have not noticed any difference.

Thank you so much! I have much to learn! It does get awfully dry here in winter. I’ll amend the amounts.
