surfactants and emulsifiers
I am working on a project that is a combination of oil and water, it contains about 14% oil. In addition to that 20% is sodium chloride. I am trying to get the mixture to first become a stable mixture while decreasing surface tension, (and here is where the problem comes in) and keep the viscosity very low (sprayable). I am trying to stay as natural as possible also.
The biggest problem that I am having is with that much salt surfactant that I have tried just thickens up to the point of shampoo consistency.
Any ideas and thoughts would be greatly appreciated.
I have not done much chemistry since college but find myself with another business venture that requires some. -

Use a surfactant that is not liable to thicken with salt.

20% NaCl in a o/w emulsion? Stable? Low viscosity? Sprayable? - good luck with that.

It sounds like you are trying to creating a sprayable emulsion that also includes a surfactant.
(1) 14% is a lot of oil to get into solution, you might consider dropping that down significantly.
(2) 20% NaCl … perhaps more like 2% … perhaps 20% is a typo
(3) Use Sucrose Stearate as the emulsifier. It will create a milky white emulsion that is water-thin.
