Gallates – toxicological data and a pilot study on the prevalence of contact sensitization

Propyl, octy- and dodecyl gallates are largely used in food, cosmetic and pharmaceutical industry as additives – preservatives. The main source of exposure non-related with food consumption is their use of cosmetic products. Gallates are classified as skin sensitization human health hazard. This research aims to evaluate the prevalence of contact sensitization to gallates and to estimate the possible cross/concomitant sensitization to gallate mix and other cosmetics ingredients among cosmeticians and cosmetology students. Skin patch testing with Gallate mix along with 19 other haptens was performed among 109 participants – 37 cosmetology students, 26 cosmeticians, and 46 controls. The study established high prevalence of contact sensitization to gallates, with higher risk for students (45.9%) and cosmeticians (38.5%). A significantly higher (р = 0.008) prevalence of co-sensitization to decyl glucoside was established for the control group. Proper risk information, with complex programs for prevention of occupational skin diseases should be provided.
