Master Batch Soap Oils #6

Time to make another Master Batch of oils. I have been enjoying adding extra butters in holiday soaps to make them more luxurious, but it’s a bit of work running it through the lye calculator each time.

Bumping up the percentage butters from 10% to 15% has seemed to make my soap a little softer. So I am going to stay with 10% butters, just a bigger variety of them.

I doubled my Extract additive from 1% to 2% – hoping to get more of the benefits of them. And I bumped up my Palm Kernel Flakes from 5% to 7.5%, while decreasing the Palm oil proportionally. (Palm Kernel has a higher INS value than Palm Oil, so this should help create a harder bar. But I have found that Palm Kernel also accelerates trace, so I hesitate to add too much).

I have gotten some lovely oils and wanted to incorporate them all, so this is a larger variety of oils than you need, but I enjoy using them and like all the benefits of them.

I have been enjoying using this new blend of oils – they aren’t as dark as the last batch (less olive oil) and I have not had any acceleration issues with the higher amount of Palm Kernel Flakes. (For the next Master Batch, I may try increasing the Palm Kernel even more.)

  1. I will like to know what is the shelf life of your end product as hazelnut Oil have a short shelf life of 6month.

      I am blessed with having a large fridge & freezer for my use and have frozen my Master Batch jugs in the past. However, I seem to use up a batch in about 4 months, so it’s not really an issue.

      The freezing will stop the aging of the oils and the refrigerator will slow it down.
