If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Poisons A and B/

/LABORATORY ANIMALS: Acute Exposure/ Acid Green 25 was investigated with regard to its eye irritation and staining properties. 0.2 mL of a 10 % aqueous solution was repeatedly applied to the conjunctival sac of one eye of each of the 6 or more albino rabbits per group for 4 weeks (twice daily on five days per week; 40 applications in total). One hour after each application, the eyes were scored for irritation according to the Draize system and for evidence of staining. In addition, scoring took also place the next day just prior to the first application of that day. A 10 % aqueous solution of Acid Green 25 did cause a slight or spotty discoloration in the orbital tissue of some animals under the described test conditions. One hour after the application (figures are given for day 5) a mean irritation score of 2 was determined, indicating that immediately after application mild irritant effects were present. 24 hours after the applications of the 10 % solution no indications for eye irritation were noted at any scoring throughout the entire study period. No dermal irritation was observed during the epidermal induction in the control group. As Acid Green 25 epidermally applied at 50 % in 1 % CMC causes black staining of the skin, erythema formation could not be evaluated. However, no edema formation was noted. Since a black discoloration was also observed after removal of the challenge patch, depilation was performed 3 hours prior to challenge reading. Skin reactions were observed neither in the control nor in the test group. No test substance-related clinical signs of toxicity were observed. Acid Green 25 had no skin sensitizing effect under the conditions of the Maximization test, in which the skin barrier is compromised.
/LABORATORY ANIMALS: Subchronic or Prechronic Exposure/ Acid Green 25 dissolved in bi-distilled water containing 1% CMC was administered daily to groups of 10 males and 10 female Wistar HanIbm WIST(SPF) rats by gavage in a total volume of 10 mL/kg bw 100, 300, 1000 mg/kg bw/day over a period of 13 consecutive weeks. In addition, an equally sized control group received the same dose volume of the vehicle. Homogeneity and the stability of the test solutions were evaluated. Mortality was checked twice daily, clinical signs were recorded once daily. Detailed clinical observations, individual body weights and food consumption were recorded weekly. An ophthalmological examination was performed in all animals before treatment and at week 13 for the control and high dose group only. During week 13 relevant parameters of a functional observational battery (modified Irwin screen test) were evaluated as well as grip strength and locomotor activity. Clinical laboratory investigations (hematology, blood/clinical biochemistry and urinalysis) were performed at the end of the treatment period. All animals were subjected to a detailed necropsy and a number of organs (adrenals, brain, heart, kidneys, liver, ovaries, testes, spleen, thyroid and thymus) were weighed and several tissues and organs were fixed and stored for further examinations if required. No substance-related mortalities and significant clinical signs were noted in the treated animals. Discoloration of faces and gastrointestinal tract was noted in all treated groups. No test item related findings were noted in the weekly performed clinical observations. The functional observational battery as well as grip strength and locomotor activity measurements in week 13 did not reveal test item related effects. No effects were noted with regard to body weight, body weight development and food consumption during the study period. At necropsy, effects on organ weights were noted for kidney only. The absolute and/or the relative kidney weight increased for both sexes at 300 and 1000 mg/kg bw/day, being more pronounced at 300 mg/kg bw/day. The kidney/brain ratio also revealed statistically significant increases at both doses or at 300 mg/kg bw/day only. A detailed analysis of the individual data revealed no clear dose response and that effects were seen for one parameter only (absolute weight increased, relative not, etc.) Furthermore, the brain weights (absolute and relative) in females were slightly decreased compared to control controls for all treated groups, without revealing a dose-response relationship. Some changes in hematology parameters were found at the highest dose level. Urinalysis revealed a significant increase in urine volume in males of the high dose group. No abnormalities were noted in the histological investigation or with regard to markers of kidney physiology.

wherein n is a number from 0 to 2 and HX represents an inorganic or organic acid. The process includes reacting 2-methoxymethyl-4-nitrophenol with a halogenacetamide to form 2-(2-methoxymethyl-4-nitrophenoxy)acetamide; rearranging the 2-(2-methoxymethyl-4-nitrophenoxy)acetamide to form 2-methoxymethyl-4-nitroaniline and then catalytically hydrogenating the 2-methoxymethyl-4-nitroaniline and, when n=1 or 2, subsequently reacting with the inorganic or organic acid, to form the 1,4-diamino-2-methoxymethylbenzene of formula (I), or the salt if n=1 or 2. Compositions and methods of dyeing hair containing the 1,4-diamino-2-methoxymethylbenzene or its salt are also described.
