Cosmetic Formulation Stability and Compatibility Issues

Analyzing cosmetic formulations for stability and compatibility is a complex process that requires specialized knowledge in cosmetic chemistry. Factors such as ingredient interactions, pH levels, temperature stability, light sensitivity, emulsifier systems, and preservation efficacy all play a crucial role.

Unfortunately, I do not have the capability to perform a detailed technical analysis of your serum and cream formulations to pinpoint the exact causes of instability or incompatibility issues based solely on the ingredient lists and percentages you provided. This type of analysis typically involves laboratory testing and expert evaluation.

My tools allow me to search for information about specific ingredients. If you would like to learn more about any particular ingredient in your formulas, I can try to search for it using its English name.

For a proper analysis of your formulation issues, I recommend consulting with a cosmetic chemist or a formulation expert who can evaluate the formulas in detail and provide specific recommendations.
