Hello Carbomer does not tolerate acidity or low pH. The formula uses Vitamin C Type ascorbic acid which is acidic. And make the formula have a low pH and make the gel texture a problem. The overall formula has 2 problems. 1. Choosing Carbomer cannot be used in this manner. Please use Gel Maker that can withstand acidity, such as Pro Polymer instead of 2. Vitamin C type ascorbic acid cannot be used in a formula like this. because it is unstable in water formulations. Members can study restrictions on use. ascorbic acid can be obtained from the website. Product details for this formula. To minimize modifications and can be mixed up into a formula Recommend to change Vitamin C type ascorbic acid to Ethyl Ascorbic acid which will be Vitamin C , a stable type that can live in water.

Hello, from the order history, it was found that the member used to order. AnyGel use AnyGel 1% creates a gel texture instead when mixed. disturb the members วัดค่า pH and notify the team again. If the pH is not lower than 2, there will be no problem. However, the team only knows that in the formula, members have Vitamin C type L-ascorbic acid and water, that's all. If there are other ingredients as well Please inform all for the team to check no ingredients to cause problems
