How to stop crystals forming in hair salt spray formula
I am working on a salt spray formula of:
Aqua - 54%
Alcohol denat. - 28%
Magnesium Sulphate - 5%
Sodium chloride - 4%
Other - qs
I am noticing large crystals forming inside the formula up the dip tube for the spray lid. I’ve never seen this before, does anyone have any ideas as to what these crystals are? Salt or Magnesium Sulphate? And what I could add to prevent recrystallisation?
