How to integrate herbal extract powders in topical skincare products? (When no liquid form is avail)
Herbal powders are often used in skincare as non treatment treatments. A good example is licorice root, which is used to reduce inflamation in both atopic dermatitis and acne - Dan of Acne.org even uses it in his Glycolic acid formula: Water, Glycolic Acid, Sodium Hydroxide, C12-15 Alkyl Benzoate, Cetyl Palmitate, Sorbitan Stearate, Glycerin, Cyclomethicone, Glyceryl Stearate, Butylene Glycol, Licochalcone (Glycyrrhiza glabra(Licorice) Root Extract), Tocopheryl Acetate, Squalane, PEG-12 Glyceryl Distearate, PEG-100 Stearate, Magnesium Aluminum Silicate, Xanthan Gum, Sorbic Acid, 1,2-Hexanediol, Caprylyl Glycol.
Now, in the case of licorice root it’s easy, just buy the liquid extract e.g. from lotioncrafter. But for say Pine Bark extract, do you a) try to solubilize the powder (I assume this won’t work) b) make a liquid extract using glycerin c) make a liquid extract/tincture using alcohol or d) find someone who can make b or c for you?Basically I’m asking for best practices in making liquid glycerin based extracts from powdered standardized ones
