Salt Master Batching Oils – #3

My last 400 oz batch of Salt MB oils lasted me one year. And although I had just made several batches of salt bars and knew I wouldn’t need this for several months, I went ahead and made a new batch of oils to have on hand, bumping the amount up to 500 oz.

I knew I would get busy with making Holiday soaps, so I didn’t want to stop my momentum in case I was asked for a special batch of salt bars (which I was). I have held off on posting this Blog until I start using this master batch.

After combining and cooling, these oils go into the freezer to maintain freshness and stop the aging process of the oils so they will be as new as the day I made them when defrosting to use.


The Plan & Reality:
A basic recipe for salt bars is 70% Coconut Oil and 30% other oils. I have simplified my recipe from the previous one, where I used lots of leftover bits of oils I had on hand (which were frozen and still fresh).

I wanted to bump up the butters for a more luxurious soap, increasing them from 5% to 10%, using both Avocado and Shea butters. I also added Rice Bran oil, as it’s properties are similar to butters.

I decided to forgo the Palm oil for two reasons: salt bars are so hard they don’t need extra hardening from the Palm oil, and I thought it would be nice to have some Palm free soap for anyone that doesn’t find using sustainable Palm oil acceptable or just feels better to go Palm free.

I always like to include 5% Castor oil for lather (above 5% seems to cause acceleration). And I like the healing properties that Apricot & Sunflower Seed oil provide.
Recipe: 500 oz oils; 31.25 lbs; 44.4 lbs soap (plus PH salt)
5%    Apricot Kernel Oil               25 oz     709 grams
5%    Avocado Butter                    25 oz     709 grams
5%    Castor Oil                              25 oz     709 grams
70%  Coconut Oil (92 degree)   350 oz   9922 grams
5%    Rice Bran Oil                        25 oz     709 grams
5%    Shea Butter (organic)         25 oz     709 grams
5%    Sunflower Seed Oil             25 oz     709 grams

Total oils: 500 oz/ 14,176 grams

I melt all of these oils in containers in a microwave oven, then mix them together in a huge bucket and divide into five 1 gallon jugs and put in a freezer until I’m ready to use them (this stops the aging of the oils.)


After measuring & heating the oils & butters, they all go into a bucket and are stirred thoroughly to blend together

I entered this recipe into a Lye Calculator (I used Bramble Berry’s (found here) at my usual 10% Super Fat and then resized the batch over a dozen times to get different batch sizes. I then copied those down, with calculations included for the additives – here are some examples:

I started to kick myself for using up all of my 92 degree Coconut oil in this batch. Salt bars are so hard, it would have been better to use the less expensive 76 degree Coconut oil. However I go back and forth with this decision, as I didn’t have any 76 degree on hand and would have had to purchase it just for salt bars – with my dedicated soaping freezer full to the brim, I would have then had storage issues.
