A lipophilic surfactant is an alternative method to enhance the glutathione partition. The purpose of this study was to determine the apparent partition coefficient (APC log) of glutathione; glutathione with additional surfactant at different HLB value of HLB 4.3; 5.5; 7; 11 and selected HLB was studied for penetration. The study was conducted by dissolving glutathione in water plus various HLB surfactants. Determination method of partition coefficient was done by shake flash method. The penetration test was conducted using the parameter of decreasing Matrix Metalloproteinase-1 expression on the balb-c male skin. The results can be used as a reference for topical glutathione formulations as these results are preformulation study. publisher: International Journal of Drug Delivery Technology 2018 type: Article type: PeerReviewed format: text language: en identifier: http://repository.uhamka.ac.id/id/eprint/874/1/IJDDT%2CVol8%2CIssue2%2CArticle1.pdf identifier: Fitria Nugrahaeni, Fitria dan Dewi Melani Hariyadi, Dewi dan Noorma Rosita, Noorma Partition Coefficient and Glutathione Penetration of Topical Antiaging: Preformulation Study.
