Help with formulation of serum
Can someone tell me if this formulate would be good for a hydrating serum?
Water 66.9%
Hyaluronic acid 1.5%
Rose oil 0.5%
Aloe vera 3%
Xanthan gum 1%
Lecithin 1.5%
Glycerin 5%
Panthenol 3.5%
Vitamin e 1%
Vitamin c 10%
Ethylhexylglycerin 0.6%
Pe9010 0.5%
Niacinamide 5%
Also, is it possible to make the formula a pinkish color, or a mother of pearl color? Or add sparkles? I know it seems childish but I am trying to market it as a serum based on Aphrodite

Why 0.6% ethylhexyl glycerine? - You get it with Ashland’s PE 9010. Might increase 9010 a bit and add something for fungi and Gram + bacteria.

The xanthan gum + glycerin + panthenol may be a sticky combo, so you might want to test it out. If you are using 1.5% hyaluronic acid, you may not need that much additional xanthan gum.
The vitamin c may not be in the compatible pH range with the niacinamide, so you will have to consider the choice of vitamin c.

i would reduce the xanthan gum to .2%-.4%
is the aloe vera the powdered concentrated version? i would use it at.1-.5%
you can remove ethylhexylglycerin and leave pe9010 at 1%
panthenol can be used at.1-.5%
why is lecithin in the formula?
do research on the type of vitamin c you are using to see compatibility, % range, and ph range
you can use micas for the shimmer, sensient has a wide range of shades
HA can be reduced if you want a thinner serum it is at a high %
vitamin e can be reduced , it will not solubilize in this serum so it might seperate
hope this helps

Will the mica powder stain the skin?

Niacinamide together with ascorbic acid (I wonder if Vitamin C is ascorbic acid in your formula) can give Niacinamide Ascorbate with bright yellow color
