Staining Liquid Lipstick
So I am formulating a Liquid Staining Lipstick which is Isododecane & Trimethylsiloxysilicate base. I am trying to achieve the maximum Stain potential for clients to claim extremely long lasting. I am using Red 27 and Red 21 Staining pigments (not the Lakes) but I am not getting the intense bright pink I am used to seeing. Is there any way to increase the intensity or stain power ? I am currently at 3 % of each pigment.

Any thoughts on the above ? Still can’t solve this problem. It seems that due to the lipstick being a “semi permanent” that dries down, setting the color in place, that creates a barrier to not allowing the staining pigments to adhere to lips and work with the pH. Any work around ?

That is a LOT of pigment, but then you are going for the stain so thus it must be that way. Since delivery seems to be the main problem, perhaps change the vehicle from a siloxane derivative to an organic one (i.e. isostearic acid) As for intensity, is there any whitening in your grind, i.e. titanium dioxide? That adds brightness if I recall.

Shade matches dictate whether there is TiO2 in the formula or not…. Either way I do not think it will pass the barrier formed by the Isododecane solvent base. I am coming to the conclusion there is not a way to have these dry down, transfer resistant liquid lipstick formulas with a stain that will penetrate the lip and add even more long lasting properties.
