The yellow Cloure is coursed by the Tiosulfate that oxidates. if that process is gone to fare the product will no longer work very well. Although your ph is very important you need a ph of at least 10 -11 to have a propper function of that kind of product.

The discoloration and inactivity of hair removal creams could be due to a variety of reasons such as oxidation, degradation of active ingredients, microbial contamination, or improper storage conditions. Though pH and texture might remain unchanged, other properties of the formula can shift over time. It’s important to thoroughly investigate to pinpoint the exact cause and formulate a solution.
To fix it you first need to figure out what is the exact cause. Stability testing or a knockout experiment could help. If oxidation is the issue, incorporating antioxidants into your formula could help. If degradation of the active ingredient is causing the problem, then adjusting its concentration or stabilizing it with appropriate compounds could be a potential solution.
