I plan to use Galactomyces Ferment Filtrate 100% purely as a final product. I have two main questions regarding its stability and use: 1. If I use the raw material purely (100%), is it necessary to add an additional broad-spectrum preservative, or is the preservative already contained within the raw material sufficient? 2. What are the correct storage conditions? Can this ingredient be stored at normal room temperature, or must it be kept refrigerated (4°C to 8°C) to maintain its stability and shelf life?

I am formulating a facial spray mist and encountered a significant solubility issue. When adding Vitamin B6 (Pyridoxine Hydrochloride) to the main water phase, the entire solution became 'crystally and sparkly' and would not dissolve. My mixing process involved: 1. Dissolving Sebum-Reg™ (Capryloyl Glycine) in a portion of water using Sodium Bicarbonate (to achieve a higher pH necessary for Sebum-Reg™ dissolution). 2. Adding this high-pH Sebum-Reg™ solution to the main water phase. 3. Adding the Vitamin B6 afterward. The final pH of the resulting mixture was 4.6. I suspect the initial high pH environment created during the Sebum-Reg™ dissolution step caused the B6 to precipitate, even though the final pH was acidic. What is the proper procedure or advice for successfully dissolving both Vitamin B6 and Sebum-Reg™ in water for a stable facial mist formulation?

I am attempting to incorporate **PoreNin™ (Tannic Acid)** powder into a water-based formulation (serum or facial mist spray). I found that the powder is extremely difficult to dissolve in water, even with electric whisking. My current successful method is: * Making a slurry in `propanediol`. * Allowing it to sit for some time in the `propanediol`. Are there any other recommendations or alternative methods for effectively dissolving **PoreNin™ (Tannic Acid)** in a water-based serum or water-based facial mist spray?

I am attempting a **Hot Process** formulation using `Sucrose Cream Maker` in the oil phase. The oil phase consists only of Mineral Oil and Sucrose Cream Maker. When heating the oil phase to approximately **40°C** to ensure all solids dissolve into a liquid, I encountered two persistent issues (tried 3-4 times): 1. The `Sucrose Cream Maker` did not fully melt or dissolve. 2. Smoke started appearing, even though Mineral Oil and Sucrose Cream Maker should be stable at temperatures much higher than 40°C. What steps or precautions should I take, especially regarding the melting temperature and the smoking issue, when using `Sucrose Cream Maker` in this technique?
