Dissolving Licorice Extract (Glabridin 40%) in Ethanol or Butylene Glycol

Licorice Extract (Glabridin 40%) can be dissolved in both Ethanol and Butylene Glycol.

While it is possible to dissolve it without heat, the product information recommends using heat at 50-60°C to help the dissolution process occur faster and more easily. Dissolving without heat may take longer or require more effort.

Regarding which solvent is better, the product information states that Glabridin can be dissolved in either Butylene Glycol or Ethanol. It does not specify that one is significantly better than the other for dissolution. Both are presented as suitable solvents, provided you use an adequate amount – specifically, the formula needs to contain Butylene Glycol or Ethanol in an amount at least 10 times that of the Glabridin being used.

The choice between Ethanol and Butylene Glycol may depend on other factors in your overall formulation, such as desired texture, skin feel, or compatibility with other ingredients.
