I am encountering formulation issues with the following ingredients: 1. `Retinaldehyde` 0.1% used with `UltraSolve` 3% and `ActiveProtec UV` 1%. I followed the admin's advice, but it doesn't dissolve. I reduced the concentration to 0.03%, and it still didn't dissolve, requiring heat to dissolve it. Should heat be used? If so, what is the maximum temperature? (But it really doesn't dissolve without heat). 2. `Adenosine` 0.5%. It is stated to be water-soluble but does not dissolve. I tried heating and adding `Propylene Glycol`, `Ethoxydiglycol`, which dissolved it completely into a clear liquid (like a watery toner). However, it later precipitated. I tried again using `Sponge Gel`, but after refrigerating, significant precipitation occurred along the bottle sides. How can I make a watery toner (`น้ำตบ`) formulation with Adenosine without precipitation? Even in a gel, it still precipitates, but I prefer a watery toner. 3. `Clover Flower Extract (Biochanin A 98%)` 0.5%. It is very difficult to dissolve. I tried dissolving it in `Isopentyldiol` 5% but it didn't dissolve. It dissolved with heat, but I'm unsure if it can tolerate heat. In summary: * Can `Retinaldehyde` be heated? How to dissolve it if not? * How to prevent `Adenosine` precipitation in a watery toner formulation? Even in gel, it precipitates. * Can `Clover Flower Extract` be heated? How to dissolve it if not?
