The only change in this soap from Alkanet Experiment 1 is that it is superfatted at 15% instead of 8% - almost double. As you can see, the colour is very much the same. So, if I can make a conclusion based on only having carried out 1 experiment - alkanet colour results in soap are NOT related to superfatting.
Ah, there was actually 1 other difference in this soap. In the Essential Oil blend, this time one of the three oils is Benzoin, as fellow blogger mentioned that Benzoin may be a good fixative for Essential Oil scents. I have not used Benzoin before... and I have also never had this chunky thing happen before. This soap traced so quickly that it got kind of chunky. Can you see it on the top? I am blaming this on the Benzoin but I suppose it could be related to the high superfatting?
CONCLUSION from Alkanet Experiment 2
- Alkanet colouring in soap is not affected by increasing Superfat content
Getting back to the list of advice for altering Alkanet colour in soap:
- Changing water quantities in the soap
- Using different oils
I am adding two new possible suggestions from Michelle at http://soappixie.blogspot.com/
- Using oils in your recipe that produce a relatively white soap
- Avoid fragrance or essential oils that will drastically change the shade of your product
