Solubility of Minoxidil in Methanol, Ethanol, 1-Propanol, 2-Propanol, 1-Butanol, and Water from 278.15 to 333.15 K

The conversation discusses two methods for making topical finasteride: using ethanol and propylene glycol or mixing it with topical minoxidil. The focus is on solubility and absorption, with a suggestion to crush pills finely and possibly mix with minoxidil at a slightly elevated temperature.

A user discusses their experience with dissolving high concentrations of minoxidil in various ethanol/PG ratios and mentions difficulties with combining it with RU58841. They note that a 5% minoxidil solution remains stable, while higher concentrations tend to precipitate.

A minoxidil solution with only ethanol and minoxidil may not be properly absorbed without additional ingredients like propylene glycol or vegetable glycerin. It's suggested to use a reputable brand and test the product for authenticity.

RU-58841 does not dissolve well in common Minoxidil solutions due to water content, requiring a 70/30 ethanol/propylene glycol mix. Users report using separate solutions for RU-58841 and finasteride/Minoxidil for better results.

The conversation is about the effectiveness of Minoxidil formulations with different alcohol and propylene glycol (pg) ratios. The user finds that a formulation with 20% pg and 80% ethanol dries faster but is concerned about absorption time.

Minoxidil can be used with isopropyl alcohol to create topical spironolactone. Spironolactone may dissolve better in ethanol or propylene glycol.
