2% Salicylic acid in calming gel formula.
Hi there. I've been working on the perfect formula for this. I made a batch last night and it actually cleared most my black heads instantly. But it also stung a bit while it was on. Please read my formula and let me know if any feedback. Should i adjust the pH?
Anyways let me explain the formula. (All water used in this recipe was distilled water).
First i made a 10% SA solution in propanediol with a small amount of polysorbate 20 added as a stabilizer. (This was prepared a few weeks ago).
Next i made my gel out of hydroxyethylcellulose (HEC) and water. I used 2 percent HEC. I also added in a very small amount of Dr. Teal's Elderberry scented, magnesium bath salt. I used some propanediol to premix the HEC.
The next day, the gel was ready and i refridgerated it.
My next step was to make a preservative solution. I made a 10 percent solution of sodium benzoate in water and set that aside.
Finally i combined, 20 grams of my SA solution, 3 grams of my sodium benzoate solution, one drop of cherry blossom fragrance and then 77 grams of the HEC gel. Final weight was 100 grams.
For color, i dipped a toothpick into curcumin powder and gently swirled it into the solution.
After gently mixing (to avoid air bubbles) the end color was opaque but golden from the curcumin.
Texture was perfectly smooth and slippery. Scent was heavenly.
I tested the pH and i got exactly 3.0.
