From: Stabilization of ferulic acid in topical gel formulation via nanoencapsulation and pH optimization
Cumulative active permeation (a) through treated and untreated polysulfone membranes, and Strat-M membrane (skin mimic) from Gel B, and (b) through Strat-M membrane from ferulic acid aqueous solution, nanoencapsulated ferulic acid dispersion, and Gel B. Data represent mean ± SD (n = 3). Significant difference (p < 0.05): *Untreated membrane versus treated membrane, treated membrane versus Strat-M, and untreated membrane versus Strat-M. #Ferulic acid solution versus nanoencapsulated ferulic acid, nanoencapsulated ferulic acid versus Gel B, and ferulic acid solution versus Gel B. ##Gel B versus nanoencapsulated ferulic acid and ferulic acid solution. **Ferulic acid solution versus Gel B and nanoencapsulated ferulic.
