Photochemical Stability of a Cotton Fabric Surface Dyed with a Reactive Triphenodioxazine Dye.

The paper describes the photochemical stability of a commercial triphenodioxazine dye (Reactive Blue_204) linked onto a cotton fabric. Preliminary studies have shown that as a result of irradiation, the dye and its photodegradation products can pass directly onto the skin under conditions that mimic human perspiration and cause side-effects. The cotton dyed fabric was photo irradiated at different time intervals.

[Research on immune system response, skin and hepatic reactivity in laboratory animals after retro-auricular topical administration of two reactive textile dyes].

Aim: To evaluate immune system response, skin and hepatic reactivity in Swiss mice after retro auricular local administration of two textile dyes.

Material And Methods: On 3 groups of white Swiss mice: group I (Cibacron Yellow F-4G), group II (Cibacron Orange P-2R) and control group (DMSO dimethylsulfoxide), substances were applied on left retro auricular ear, in dose of 25 microL solution 10% in DMSO (the dyes were not soluble in water), once a day, for 7 days. After euthanasia, blood samples were taken to assay differential cell count, peripheral neutrophils activity (NBT test), serum opsonic capacity, peritoneal macrophages activity (phagocytic and bactericidal capacity), and activity of spleenic T-lymphocytes with rossetting capacity, and spleen cells forming Jerne plaques.

[Experimental study of immune reactivity in Swiss mice due to topical administration of three textile dyes].

Unlabelled: Reactive Red 183, Reactive Red 2 and Reactive Blue 204 (red dye, green dye and blue dye) are three reactive dyes frequently used in textile industry. In some atmospheric conditions ( high temperature, perspiration, pH values, UV/IR radiations), some quantities of these hydrolyzed dyes, could pass from textile clothes directly into the human skin.

Material And Method: There were used 4 groups of white Swiss mice (with similar weight and number of both sexes), control group and 3 groups, treated once daily with a retro-auricular application of different reactive dyes.
