ingredient for producing fine particle makeup fixing spray

looking for a ingredient to produce a fine mist spray suitable for a make up fixing spray.
main ingredients are water, alcohol and a film former which is our secret ingredient. Its nothing amazing but is a low concentration of mix of gums.
Are there any dispersants to try make a thinner mist?
Have tried polysorbates, and quats so far.

    Could you work around your pH for the gums to be less thickened and eventually a thinner mist???????? Maybe the pH of your product is optimum for the gums to thicken and give viscosity????? Maybe a little play with the pH could help?????
    Its a very blind shot and I might be completely off the line though.

    cssci21, I'm reasonably sure you are without a fix here.  My guess is it isn't viscosity making your product "stream" instead of spray, it is polymer chemistry. Long-chain polymers, which may comprise one or more of your film-forming gums,do not lend themselves to atomization in a spray format, unless they are at very low levels of concentration.  In the event I'm mistaken, however, just add a little salt along with a little alkanolamide (to prevent clogging the spray valve.)

    To check if @chemicalmatt is correct, buy a powered sprayer to test with, so things like spring strength and orifice size are less of a problem.

  • hello everyone,
    strangely it has been solved by removing the alcohol and having only water and the low level of gums.
    Not sure how that works but viscosity seems to be the same must have been some interaction going on...

    @cossci21 Thanks for letting us all the know the real culprit.
