I am developing a gel-cream formula with the following ingredients: 1. `Carbopol Ultraz 21` 2. `Triethanolamine` 3. Actives: `Alpha Arbutin`, `Tranexamic Acid`, `B3`, `vit c (GO VC)` The problem I encountered is that after storing the cream for a while, it changed from white to light brown and developed a sour smell. I then tried preparing the formula again by adding `Active Protec ™ OX` 1% to the water phase. I found that the cream became thinner, resulting in a lotion-like texture, and thickened when in a high-temperature room. However, the color of the cream did not change at all. I would like to know what adjustments I need to make or if there are other anti-discoloration and anti-odor agents that would be suitable for this gel-cream formula. Please advise.
