    Hello, my name is Priscilla Cortes.I’m a newbie and stumbled across this forum while researching wholesale distributors for cosmetic bases. Please excuse if I don’t express myself correctly as I’m not a chemist, just a cosmetic enthusiast! Trimethylsiloxysilicate has been the one ingredient that I still cannot get my hands on. There is a box sitting in my house full of waxes, silicones and oils that I plan to use to formulate my own lipstick and eyeliner. However, I’m specifically interested in trimethylsiloxysilicate due to its film forming and water repellency attributes. My research has only led me to dow corning and shin etsu, but how do I order? Is this available to individuals with small businesses or just large factories? I wonder if I can still get a functional product without this ingredient?

    Priscilla, your only hope for this is to find a distributor that will sell to a small business. Most distributors will not, for liability reasons. The biggest problem for liability is that if you, as an untrained formulator, produce a product that harms you or someone you give/sell it to, the supplier could get sued for letting you have a material that only a professional should be using.

    You can easily make lipstick and lipgloss without MQ Resin. In fact, you should, so that you get an idea of how your formulas perform without it.
    I would very, very strongly advise you against making eyeliner. Any product that gets that close to the eye has the potential to do enormous harm - if you don’t have the resources to do the safety and microbial testing, you should stay far away from it.

    Hi @Bobzchemist. I recently came up with a lipstick formula composed of isododecane, silicone gel (cyclopentasiloxane/ Dimethicone/Vinyl Dimethicone Crosspolymer) and a blend of waxes. The ingredients I purchased come from TKB TRADING and the conservatorie. The blend of waxes and oils is a prefabricated base. It is a light creamy stain, however, it is not what I want it to be. It doesn’t dry and has sheen. I thought that the cyclopentasiloxane in the silicone gel being a volatile fluid would leave a dry matte feel. I might be adding inappropriate amounts of ingredients. I heat everything over low heat until my wax melts and then add my pigments and blend with a handheld blender. The mixture sometimes gives me tiny clumps. Is it ok to heat silicone gel or is it only used in cold process? I work in the garage, I have blenders only for mixing my ingredients and a small electric stove. As for the eyeliner, I purchased a premade base also. It is from diycosmetics.com and presumably safe. It contains TRIMETHYLSILOXYSILICATE. I already formulate with it and added magnesium myristate and jojoba oil. Thank you very much for your expert opinion.

    This is not something that I can help with, sorry.
