Cosmetics Formulation Development

From this thread topic7421.html the staff suggested to mix Zinc PCA with Hi-EGCG™ (Green Tea Extract) can be used in a night regimen. but the web page information of Zinc PCA informs that *cannot be used with Azelaic Acid , Hi-EGCG™ , Melatonin Forte™, Atopi- Telmesteine ™, Four-EO™* is currently ordered and mixed into the same formulation using Zinc PCA 1% and Hi-EGCG™ (Green Tea Extract) 1% and started using the finished product. When these two substances are used in the same formula How will it affect and if I use Hi-EGCG™ (Green Tea Extract) in the formula, can I use it during the day? Thank you.

Hello, the team apologizes for the conflicting information. The study team will provide more information. Zinc PCA There was a problem with some ingredients. which the problem is the sedimentation of Zinc PCA Yes, this precipitation, the result is Zinc PCA is not effective on skin. because it turns into a powder in the formula and cannot be absorbed into the skin normally If the member mixes and does not find any precipitation no problem Because the team found that precipitation also depends on the pH of the formula, if not in the problematic range. no problem [For this specific The team itself is not complete. Therefore, it has to be said in general that if it can be avoided, it should be avoided in the mix.] There is no need to throw away the formula. just to filter or scoop the part where separation/sedimentation occurs Get out of the recipe

Thank you staff. From leaving the aforementioned product for about a week, I still haven't found any precipitation. This product is in the form of a gel with a pH of about 4-5. L-Carnitine 3% too

Hello, if you don't find any problems The formula is considered compatible. No problem, the pH is right for your skin.
