Lake pigments settling in “lip gloss” formulation (photos)
I am trying to formulate a tinted “lip oil” which is essentially a type of lip gloss that is runnier. To give you an idea, a product example that is available in the market is Clarins Lip Comfort Oil.
The problem I’m facing is the lake pigments in the formula tend to settle out at the bottom after a while. Now I also notice some pigment settling in the commercial product (Clarins Lip Comfort Oil) but not as much as mine. I guess some pigment settling is normal in this kind of formulation since the end product is more fluid than a typical lip gloss but I’m wondering if there’s anything I can do to minimize it? I’m already using pre-dispersed lake pigments in castor oil and my formulation is actually less runny & slightly less pigmented than the commercial product.
Below is the formula that I’m currently working with.
43% Versagel ME 750
25% Polybutene 1300
7.5% Diisostearyl Malate
8% Tridecyl Trimellitate
5% C12-15 Alkyl Benzoate
2.8% Pre-dispersed Lake Pigments (in castor oil)
2% Sweet Almond Oil
1.5% Jojoba Oil
1% Cherry Kernel Oil
1% Tocopheryl Acetate
Would mixing with an overhead stirrer help? Or would a homogenizer help?
Also, would 0.5% Phenoxyethanol provide enough protection in this anhydrous formulation?
Your help would be greatly appreciated. Thank you in advance!
