I'm developing a metallic liquid lipstick recently and make NYX Liquid Suede Metallic Matte as my benchmark. The LOI is as below:
Isododecane, Octyldodecanol, Hydrogenated Polycyclopentadiene, Ethylene/Propylene Copolymer, Cera Microcristallina / Microcrystalline Wax / Cire Microcristalline, Tin Oxide, Water/Aqua/Eau, Calcium Aluminum Borosilicate, Glycerin, Sodium Chloride, Silica, Alumina, Aluminum Hydroxide, Synthetic Fluorphlogopite, BHT, Phenoxyethanol, Barium Sulfate (CI 77120). MAY CONTAIN / PEUT CONTENIR (+/-): Red 7 (CI 15850), Yellow 5 Lake (CI 19140), Blue 1 Lake (CI 42090), Red 28 (CI 45410), Red 30 Lake (CI 73360), Carmine (CI 75470), Iron Oxides (CI 77491, CI 77492, CI 77499), Manganese Violet (CI 77742), Titanium Dioxide (CI 77891), Mica.
I found that the formula contains water without any emulsifier. May I know if do I miss any emulsifier or how can it works without emulsifier? What's the theory behind?
Can anybody help me to figure it out?
Many thanks in advance!!!!
