Cosmetics Formulation Development

Have ordered Urea Go for a trial and on the instructions page use Gluconolactone in approximately 15% of Urea to Stabilize Urea which found that when using this ratio, the pH value falls to more than 3, which the pH range used is 4-5.5 I want to know that 1. Can reduce % of Gluconolactone to get the pH in Can it be in the 4-5.5 range? Is it possible to stabilize or not? 2. If using the % according to the ratio above, can other alkalis be used to adjust the pH in the formula?

Hello, 1. Yes, the optimal pH will be around 4.0-4.50. Try to adjust the proportion like this. (In case the formula is actually used to produce must be adjusted to be in the range of every lot because each lot of raw materials produced has a pH range, not a fixed value) 2. It is not recommended to add alkali, use Gluconolactone in proper proportion. fit the desired value No need to add more alkaline.
