Thomas-Wilson, Amelia published the artcileReplacing Synperonic N in the Physical Developer fingermark visualization process: Reformulation, COA of Formula: C14H31NO2, the publication is Forensic Science International (2021), 110786, database is CAplus and MEDLINE.
The Phys. Developer solution currently recommended for use in the United Kingdom for fingermark visualization uses two surfactants: n-dodecylamine acetate (nDDAA) and Synperonic N. Synperonic N is covered by the EU directive 82/242/EEC, which sought to phase out chems. with degradation products more harmful than their precursor. This study explores the replacement of Synperonic N with alternative detergents and examines their ability to produce clear, stable solutions that are effective at developing fingermarks. The critical properties of the detergents were investigated, such as the critical micelle concentration and the hydrophilic-lipophilic balance, and planted mark comparisons were performed on promising formulations. Tween 20 was deemed unsuitable due to the production of cloudy solutions and the requirement to age the formulation to improve effectiveness. Brij C10 produced clear formulations; however, these were too stable causing unacceptably long exhibit processing times, and an addnl. preparation stage was necessary. Brij L23, Brij S10, Igepal CO-630, Polyoxyethylene (10) tridecyl ether and Tergitol 15-S-9 also proved to be unsuccessful alternatives. Decaethylene glycol monododecyl ether (DGME) was found to be a suitable alternative to Synperonic N and depletion series experiments suggested that a range of DGME and nDDAA detergent quantities were effective at developing marks. The processing time using DGME was similar to Synperonic N and the most favorable ratio of reagents is proposed in this paper as a reformulated Phys. Developer solution
