  • castor oil and octyldodecanol difference at liquid matte lipstick

    Posted by Anonymous on November 3, 2019 at 8:41 pm
    we manufacture all make up products in turkey
    matte liquid lipstick(isododecane based) when we use castor oil for grinding red7
    (cı15850) at 3 roll mill and when we put at base of matte liquid
    lipstick red7 is not open it self but if we use caprylic capric
    trigliseride or octylodedecanol its solving on matte lipstick base.
    what is the problem at castor oil ?
    In my opinion may be it causes because of polarity of castor oil
    I need your ideas..

    Caprylic Capric Triglycerides and Octyldodecanol are more polar than castor oil. I think your problem is the viscosity. Castor oil is very thick compared to Octyldodecanol, so you can’t wet your pigment properly. I haven’t worked with 3 roll mill, but this is the case with manual mixing.

    Are you saying that you’re not getting full color development with castor oil but you do with octyldodecanol/CCT?

    Seconding what @ngarayeva001 said: I don’t think polarity is the issue. And - castor oil is very frequently used for pigment grinding for its ability to wet pigments so I’m not sure we have enough information. Perhaps you could post the entire formula so we can help?

    @Sponge, you are right! I recently bought red #7 and red #6 in castor oil but my previous two were in octyldodecanol, so both should be fine.

    Is castor oil wetted pigment compatible with Isododecane in liquid matte lipstick ? @ngarayeva001 Because in my experience, castor oil will separate in IDD Based liquid lipstick.
