Need help Formulating liquid to matte lipstick
Good morning !My friend and I are creating our own cosmetics. We want to specialize in liquid to matte lipstick. A formula that glides on wet and dries to a complete matte finish. I have tired dozens upon dozens of unsuccessful batches. However, I am very close! The problems I tend to have are 1. The color is not holding 2. The completed item separates into oil/water after a day or two and 3. My lips tend to burn when I apply the liquid lipstick. I think it I am getting the burning because I am mixing the magnesium sterate with an ingredient I am not supposed to be mixing it with. I am desperate for help as doing this is very frustrating. The magnesium sterate made the formula matte and everything, but it burned my lips! The product separates and sometimes the color goes on streaky and the color does not hold. Below is a list of my ingredients that I am working with. I am not sure if I need to add more of one ingredient or completely take out one ingredient. Percentage wise I need help. Could you please give me some advice and aid me to creating a formula that dries matte and the color goes on non-streaky and holds. Thanks so much!! Any help would be greatly appreciated!Typically I add items 1,2,3,4 together and heatAdd 9 ,6 & 7 to the batchThe 12 & 13And finally either beeswax, magnesium sterate or carauba wax to hold the mixture togetherTHIS IS JUST 1 EXAMPLE OF HOW I WOULD CREATE A BATCH. AS I MENTIONED I TRIED DOZENS UPON DOZENS AND HAVE FAILEDTHE INGREDIENT I ADD THE MOST OF IS ISODODECANE. SMALLER BUT EQUAL AMOUNTS OF Cyclopentasiloxane AND dimethicone ORDimethicone/vinyl dimethicone crosspolymer. THE REST IS SMALL PORTIONS.1.Isododecane2.Trimethylsiloxysilicate / Polypropylsilsesquioxane3.Cyclopentasiloxane4.dimethicone 3505.Magnesium Sterate6.Titanium Dioxide7.Dimethicone/vinyl dimethicone crosspolymer8.Kaolin9.Colors dispersed in castor oil10.Beeswax11.Carnauba Wax12.Phenoxyethanol13.Vitamin EPLEASE INBOX ME WITH HELP -

I think this is a case where you will need to retain a Cosmetic Chemist with Color experience. There are many listed in the resources section. Many of us do this to pay the bills and I think this goes a bit beyond free advice. Just my opinion.

Great point @microfomulation
This is a very complicated project that can’t be answered in a simple post.
To get more information yourself you could conduct a knockout experiment. This will tell you exactly what ingredient is causing the stinging. -
I really just need to know what ingredients cannot be mixed together. That would help a lot

Find trial formulas for liquid lipstick on the web, and use them as starting points. Making a liquid lipstick matte just requires adding mattifying agents.
Or, you could save yourself months, possibly even years, of formulating work and just hire a consultant. It all comes down to how much your time is worth. -
Unfortunately as Mark and Perry have said, you may have to pay someone for those answers.
It’s not a simple question of what can or can not be mixed with what. Even if it was that simple of question, you need to realize that you’re asking for an expertise that you don’t have and the chemist has worked hard to gain. You have to pay for that expertise. -
Where can I find a consultant? @bobzchemist
-
If you look in the “Anouncement Need Formulating Services? Here are some contacts” formulators post their contact info. Several Color Cosmetic Specialists have posted in the last few months.
I see three who have posted since April.

You can also look on LinkedIn

Well while agreeing with all the learned specialists here my first change would be elimination of castor oil pigments and use silicone compatible or coated pigments. Then I would look for further trials. Get rid of kaolin as well if you are using it as a filler or mattifier and look for other options compatible with this kind of formula.

I am also looking for a formulator for the same project and willing to pay for the service but did not find anyone under the Need Formulating Services section nor received any replies to my post. Im not familiar with Linked In but I may have to look into that
