Effect of Tocopheryl Polyethylene Glycol Succinate on the Percutaneous Penetration of Minoxidil from Water/Ethanol/Polyethylene Glycol 400 Solutions

Creating a propylene glycol-free Minoxidil and Tretinoin solution to reduce skin irritation and enhance effectiveness. An emulsifier like lecithin can help mix Tretinoin properly, and Minoxidil foam is an alternative without propylene glycol.

RU58841 mixed with Minoxidil seems less effective over time, so the user plans to switch to a PG and Ethanol dilution for better results. They also consider using rosemary oil with Minoxidil to enhance RU58841 absorption.

The user is using Dutasteride and oral Minoxidil for hair regrowth and is considering adding topical Minoxidil but is allergic to propylene glycol, which is present in the product they found. They need a solution with tretinoin that does not contain propylene glycol.

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.

Mixing RU58841 with cetosomal minoxidil is discussed due to scalp irritation from ethanol PG vehicles. A mixture of the two turned bright pink when left to dry.

The user is experiencing an allergic reaction to propylene glycol in Kirkland minoxidil and is considering switching to a foam version or a low-PG minoxidil solution. They are also contemplating oral minoxidil but are concerned about its long-term safety.
