Emulsion separation
Please be gentle with me, as I am learning. I have made a ” facial cleansing milk” which is basically a really lightweight lotion with a soapy surfactant. I love it, and I have been using it for quite some time.
I make a gallon at a time (masterbatch) without fragrance. When I run out of it in my shower, I remove some and add the appropriate amount of fragrance (.25%). I noticed separation, so I narrowed it down to what I thought the causes might be. It isn’t a temperature issue, and it isn’t an emulsifier issue. It is completely fine, until I add the fragrance.
These are my questions:
1) Do some fragrances just cause separation as a rule? If so, why?
2) I mix my fragrance in with a stick blender. Could this be “breaking the emulsion”?
