A topical application of a nonsteroidal anti-inflammatory drug (NSAID) may induct an adverse reaction of photoallergic contact dermatitis. The occlusive usage may provoke concomitant photoallergic sensitizations to an NSAID and other ingredients. We describe a 58-year-old woman with photoallergic contact dermatitis from ketoprofen and hydrogenated rosin glycerol ester in the applied compress. O...

Gum Rosin mengalami peningkatan produksi di Indonesia tetapi tidak diimbangi dengan sumber daya alam yang maksimal, umumnya dimanfaatkan dalam bentuk non-modifikasi bidang perindustrian dan digunakan sebagai bahan pada pabrik kertas (sizing agent), tinta cetak, pernis, perekat. Namun memiliki banyak kelemahan antara lain berupa padatan atau kristal, terjadi proses oksidasi secara alami, dapat m...

The title compound, C(20)H(32)O(2), has been isolated from hydrogenated rosin. There are two independent mol-ecules in the asymmetric unit. In each mol-ecule, the cyclo-hexane ring assumes a chair conformation, while the two cyclo-hexene rings adopt half-chair and envelope conformations. Inter-molecular O-H⋯O hydrogen bonding between carboxyl groups links pairs of independent mol-ecules into di...

The title compound, C(24)H(40)O(3)·C(2)H(6)O, is a substituted tetra-cyclo-[10.2.2.0(1,10).0(4,9)]hexa-decane derivative obtained from the reduction of maleopimaric acid which was isolated from a maleic anhydride modified rosin. In the crystal, the triol mol-ecule and the ethanol solvent mol-ecule are linked by hydroxyl O-H⋯O hydrogen bonds, giving a two-dimensional network structure.
