Questions I missed: Solubility of our powdered ingredients

In this post, Lalla writes: If the solubility is 0.5% at 25°C, does it mean if we dissolve a higher concentration at say 35°C the allantoin will crystallize as it cools down? If I try to dissolve MSM and allantoin and caffeine in water, will their respective solubility decrease because of the other ingredients? Solubility is generally...

Experiments in the workshop: Facial cleanser with a ton of extracts – modified

This is kinda what happened here with this somewhat unappealing looking facial cleanser. But seriously, try...
