    U mean alcohol( not denatured) doesnt solubilize salysilic acid? I dont think so…denatured makes it unfit for consumption but why is so important in cosmetics I dont know

    alcohol increases penetration of some actives like whitening agents, but with destroying the barrier layer on skin, so in high percentage it damages substances which keeps ur skin healthy and overall it dries the skin…but the qustion here is that why should we used denatured form?or is there any problem if we use not denatured one?

    sorry my english isnt very well:( , I think perry should hold some english training classes too ;)

    we face some problems in our nail polishes(sedimentation of pigment), so we want to change the solvent. and it seems that texaphor963 is a good one. we want to buy it, which companies sells? or is there a good alternative?

    @milliachemist here dibutyl phthalate is plasticizer…it is also fragrance  in formula. resins are binders and avoid other ingredinets from sedimentation.  

    @hishne1 it dries almost in 1 minute and it isnt very glossy…

    pH has little effect on viscosity, however the highest viscosity is achieved in neutral pH…
