Solvents for Dissolving Ferulic Acid

You've asked about dissolving Ferulic Acid, specifically if Butylene Glycol can be used instead of Ethoxydiglycol, and if there are other options.

Here's a breakdown of suitable solvents for Ferulic Acid:

• Ethoxydiglycol: This is the recommended and most effective solvent for Ferulic Acid. It is known for its excellent ability to dissolve many cosmetic ingredients and enhance skin penetration.

• Ethanol: Pure-Ferulic Acid™ is also soluble in ethanol. This is another effective option for dissolving Ferulic Acid.

• Butylene Glycol: While Butylene Glycol can dissolve Ferulic Acid, it is significantly less effective than Ethoxydiglycol. As mentioned in the previous reply, you would likely need a much higher concentration of Butylene Glycol (potentially 2-3 times more) to achieve the same level of dissolution as with Ethoxydiglycol.

• Diethylene glycol monoethyl ether (DGME): This is chemically related to Ethoxydiglycol and is also commonly used as a solvent in various products.

In summary, while Butylene Glycol can work, Ethoxydiglycol and Ethanol are more efficient solvents for Ferulic Acid. Diethylene glycol monoethyl ether (DGME) is another potential option.
