Vitamin C serum, solubilizer
I
make serum with ascorbic acid + vitamin E + ferulic acid. I decide to
solve ferulic acid by propanediol (vegetable).
I
know that most companies dissolve vitamin E by Laureth-23, but I want
something more compatibile with skin (not a polyethylene glycol
ester) .
I
want to dissolve vitamin E with Polyglyceryl-4 Caprate and I’m
wondering if P4C will be good for this solution- will it be stable in
pH 3? Some documents suggest that P4C is stable at pH >4. But one
recipe of serum with ascorbic acid have P4C in formula:Perfect C Serum, ingredients:
Hamamelis Virginiana (Witch Hazel) Water, Ascorbic Acid (L), Alcohol, Glycerin, Aqua (Water), Polyglyceryl-4 Caprate, Ergothioneine (L), Buddleja Davidii Meristem Cell Culture, Solanum Lycopersicum (Tomato) Fruit Lipids, Citrus Tangerina (Tangerine) Peel Oil, Lavandula Angustifolia (Lavender) Oil, Citrus Paradisi (Pink Grapefruit) Peel Oil, Elaeis Guineensis (Palm) Oil, Fructooligosaccharides (D-beta), Beta-Carotene (D), Glucosamine HCI (D), Wine Extract, Astaxanthin, Tocotrienols, Caprylic/Capric Triglyceride, Tocopherol (D-alpha), Ubiquinone (CoQ10), Benzyl Alcohol, Xanthan Gum
What do you think, have you tried this or similar mix?
