Dimethicone cst 350 in lipstick
I am in progress of formulating a liquid lipstick. I am not a chemist, but have equipment and products I need to produce this lipstick/gloss, which will go for testing as soon as I am happy with it.
I was wondering if there is a usage limit on Dimethicone 350 in lipstick? The recommended level is 1-10%, from the supplier, but I am using 60%
Is this level too high, is there is a danger in this? From my research, it seems there is no FDA limit, no EU regulation limit- but Dimeth. does get alot of bad reviews which makes me worry about my level usage.
The reason I have used so much Dimeth is because my oil substitutes do not settle into the skin nicely. I have not managed to achieve the same results using oils such as vitamen E, Jojoba,coconut oil, and sweet almond oil.
I would appreciate any advice, or links to research. I have googled and googled but find nothing specifically on usage levels and problems associated to usage being too high.
