The inadequate attention is given currently to development and approbation of new forensic equipments within the forensic examination and in particular in the fingerprinting. Deliveries of special reagents applied to detect and fix fingerprints have been cut off by majority of foreign companies (e. g. Sirchie, BVDA, Foster Freeman etc.). In addition, absence of new developments is being recorded in this field by national manufacturers of forensic equipments. Circumstances indicated have caused the shifts in product mix, including consumables (both universal and customized) used both for crime scene investigation and in a laboratory environment - fingerprint powders. Based on the patent searches, the heuristic approach for development of new fingerprint powder compositions with enhanced adhesion ability as to sweat and grease deposits has been shown in this paper. Results of latent fingerprints detection by fingerprint powders have been illustrated on surfaces accepting fingerprints which differ in properties.
