    hi all 

    i am making matte liquid lipstick all is going well the color, the formula, matte finish. it is amazing formula.

    i am facing one issue after some time my Lipsticks casing is having some liquid on it. is it because of volatile oils i am using in lipstick that evaporating from tube?
     
    i am using dimethicon 1.5 and isododecane in making lipsticks those are volatile and evaporating from tube. if yes how can i control this issue 

    waiting for your kind suggestion

    Probably isododecane. One thing you could do is changing the casing so one doesn’t see the droplets any longer or switch out isododecane.
    Do you have any pictures? Did you remove the casing with the drops and let it sit to see if all the oil really evaporates?

    i found one issue i added castor oil in lipstick base. that is not compatible with dimethicon 1.5 may be this was the issue dimethicon seperating from base and the evaporating from lipstick tube.

    what i did i removed castor oil from the base and added dimethicon 100 instead of castor oil.. hopefully issue will resolve. 
    secondly do let me know i adding vitamin e bit now base is free from any natural oil just adding dimethicon 100

    dimethicon 1.5
    isododecane 
    cyprylic capric
    candelila wax
    carnauba wax
    cetyl alcohol
    micro crystalline wax
    these are the base ingredients
    do i still need to add antioxidant?

    You’re saying the liquid carrier is separating from the waxes/pigment?

    yes transparent white liquid is leaking from lipstick tubes

      If that’s what’s happening to you, then you need to adjust the oil/wax ratio in your formulation. The leaking in the tube means you either overfilled it or your formula is not stable, which if depending on your case (liquid lipstick must be an emulsion so check your emulsifier amount) if it’s not an emulsion then check your waxes and oil ratio. Also thickening up the formulation might help too

      You can try to use Dermofeel Viscolid from Evonik, I just used it today and definitely helped me suspend the pigments (reason that you use Bentone right?) Lecithin can also work, Hydrophobic Fumed Silica from Sensient can also help. Look up suspending agents in Prospector…
