Salt Spray Help (Part 2)
Hi,
So my first two forays into making a salt spray turned out a spray that I’m pretty happy with. However, I’ve noticed that a film forms on the surface if the bottle is left sitting for a while. I’m thinking perhaps I don’t have the proper amount of Polysorbate 20 in the recipe, or I should be using a hand blender instead of hand stirring. Here is my recipe:Water - 480gMagnesium Sulfate - 60gPink Himalayan Salt - 10gKelp Bioferment - 8gDimethicone 500 - 30gPolysorbate 20 - 30gOptiphen - 6gI’m heating the water to near boiling in pyrex, and then adding all of the pre-mixed ingredients (except the salts) at one time, stirring vigorously, then adding the salts and continuing to stir. Like I said, the product itself is great, but I’d prefer to not have a product I have to shake before each use. Am I using an improper amount of Polysorbate 20?Cheers,D -

my initial suspicion is that your Optiphen and/or dimethicone are separating
rather than trying to fix this with a solubiliser I’d suggest using a more water-soluble preservative (e.g. DMDMH) in place of the former, and a water-miscible silicone (e.g. DC 193) in place of the latter
