  • Help with formulation of serum

    Posted by sophia07 on June 16, 2024 at 7:58 pm

    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
