Thermodynamic Modeling of the Gas-Antisolvent Process for Precipitation of Finasteride

The conversation discusses using Rogain foam as a solvent for topical finasteride due to an allergy to propylene glycol. The foam's ingredients, including alcohol SD 40B, are considered suitable for dissolving finasteride for easier application without skin irritation.

The conversation discusses using minoxidil foam as a solvent for topical finasteride. Ingredients of minoxidil foam include butane, cetyl alcohol, glycerin, and purified water.

The conversation discusses adjusting the isopropyl alcohol, propylene glycol, and water ratios in a topical finasteride solution for better scalp comfort and less dandruff. The user considers using 20ml IPA, 25ml PG, and 15ml water in a 60ml bottle, moving away from mixing finasteride with topical minoxidil.

The conversation is about using distilled water as a solvent for topical finasteride to reduce systemic absorption. The user is considering avoiding ethanol and propylene glycol to achieve this.

The conversation is about making homemade topical finasteride, discussing mixing it with Kirkland minoxidil and creating a solvent with alcohol, glycerin, and water. A formula suggestion includes 50% ethyl alcohol, 25% propylene glycol, and 25% distilled water.

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.
