Sugar and Lemon Juice Fixative
This mixture is the most common for dabbing on the damp paste to keep it moist and help secure it to your skin. I prefer to use the unrefined evaporated cane juice (Sucanet) or jaggery, but many people use white sugar. I also mix mine a bit sweeter than most people I have talked to.
What you will need:
2tbsp sugar (again, I used the cane juice or jaggery)
2tbsp lemon juice
Mix thoroughly until the sugar is all liquified in the juice. I store the extra in the fridge until I need it again. So far I haven't had any problems with it, and presently there is a 2 month old batch of this in my fridge.
I have begun purchasing the large bottle of lemon juice concentrate, and simmering cloves in the juice for a couple of hours. I strain the lemon/clove juice back into the bottle and just keep in in my fridge until I need it.
