castor oil and octyldodecanol difference at liquid matte lipstick
we manufacture all make up products in turkey
In 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..
