Cosmetics Formulation Development

Dear Staff, please inquire Grape Seed Extract to AHA using the formula below From the experiment, the mixture looked like it was not dissolved into the gel 1. Lactic Acid (AHA) 90% (normal grade - smell) 10% 2. Vitamin C (L-ascorbic acid) (Fine ) 10% 3. Disodium EDTA 2% 4. Grape Seed Extract ( Proanthocyanidins ) 2% 5. Pro Polymer™ (Gel Maker) 2% 6. 1,2-Hexanediol (Super-Purified, Odorless) 3% 7. น้ำกลั่น complete 100%, thank you.

Hello, the formula is not suitable for use. 1. Grape Seed Extract Very dark color, use at 2%. Make the formula unusable 2. Lactic Acid 10% + Vitamin C 10% makes the formula pH too low, it will irritate the skin.
