The diversity of benzotriazole derivatives useful as anti- foggants is exemplified by an Ilford Ltd. Schanker has noted that gastrointestinal absorption was greatest for acidic compounds having pKa values greater than 3 and basic compounds with pKa values less than 8. Pure 2H-benzotriazole apparently has not been isolated, although numerous derivatives are stable see, for example, Benson and Savell, Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical foam. Ciba-Geigy Corporation supplies the Tinuvin compound in standard fibre drum containers with a net weight of pounds. Mice bearing either mammary adenocarcinoma or Crocker Sarcoma were treated with re- peated injections of benzotriazole or its 6-chloro- or 6-nitro-derivative. The manufacturer's specifications are given in Table 5 for benzotriazole commercial chemicals where the specifications supplement or are different from the data in Table 2. All of the compounds caused severe arrests in the gastrula and yolk-plug stages stages which caused the ectoderm of the blastocoel roof to become in- dented or bulged, and later collapsed and wrinkled. These products provide the handling ease of a liquid without the formation of an alkaline salt. Eastman Kodak Company evaluated the toxicity of 5-methyl-lH-benzotriazole in guinea pigs, when applied as a moistened solid to the skin under occlusive bandage for 24 hours. A copper sheet dipped into inhibited oil containing 0. These products are widely used in the water treatment, engine coolant and metal working industries. Therefore, the incorporation of an ultraviolet absorbing 2- 2'-hydroxyphenyl -benzotriazole compound into the emulsion or base of a microfilm, for example, makes the film opaque to the light to which the copy material is most sensitive, making it difficult or impossible to achieve clear copies. The causes of fog are complex and varied. Tinuvin type compounds are usually used, generally in combination with other UV absorbers Cantatore and Sordini, ; Compostella, and antioxidants Balaban, Fog is analogous to "noise" in electronic parlance where design parameters are usually optimized to give the highest signal-to- noise ratio possible. Effects on Isolated Organelles d. Mixtures 5 3. Although practic- ally colorless to the human eye, benzotriazole compounds absorb over a broad range in the ultraviolet region of the electromagnetic spectrum and dissipate the absorbed energy, usually not by bond breaking and free radical formation, but by harmless physical vibration and the emission of heat. One of the most widely used plastics stabilized with benzo- triazoles is polypropylene. Do not let this chemical enter the environment. In spite of the amount of attention these compounds have received in photochemical studies, it appears that 1-substltuted benzotriazoles are not particularly important commercial materials. Analytical Methods Since the middle 's, interest in developing analytical methods for benzotriazoles has corresponded to increasing use of these chemicals for anticorrosion purposes. Keep away from heat, sparks and flame. Section 7 - Handling and Storage Handling: Use with adequate ventilation. In addition to the oral toxicity studies, Tinuvin was tested for subacute dermal toxicity Ciba-Geigy Corp. Consequently, physical protection is not possible with these materials; apparently both the hydrogen atom and at least two nitrogen atoms are needed in the five-member ring to obtain anti- corrosion properties. Benzo- triazole dust is considered a severe explosion hazard Dorsett and Nagy, , besides being a health hazard if inhaled see Section III-B. Benzotriazole compounds react readily to form stable metal complexes which are capable of protecting the metal particularly copper from further chemical attack. Show this safety data sheet to the doctor in attendance. However, the effect of benzotriazoles on film speed seems to be variable. The 1H and 2. Their technique involved the direct incubation of tumor fragments with benzotriazole solutions followed by implantation into susceptible hosts to determine viability of the treated fragments. No deaths resulted and tumor growth was not inhibited by this treatment. The film is thermally and chemically quite stable. Combustion generates toxic fumes. Stabilization processing enjoys wide use wherever speed and convenience are critical such as police work, medicine, journalism, and professional studio proofing, especially when a permanent print is not necessary. Benzotriazole is used in direct-positive dye diffusion- transfer cplor processes. The oxida- tion products of the benzotriazoles are dark in color; hence, the darker the material in solution , the more impurities are present. The aqueous sodium benzotriazole solution is added to the reaction mixture containing crude benzo- triazole. Get medical aid if irritation develops or persists.

Many of its derivatives, such as the 2- 2'-hydroxyphenyl - benzotriazoles, are not soluble in water to any appreciable extent. For personal protection see section 8. Photochemistry Considering that benzotriazoles generally exhibit broad ultra- violet absorption see Section I-A-3 , the compounds which are the main concern of this work are, on the whole, remarkably stable to ultraviolet radiation, particularly at wavelengths encountered at the surface of the earth nm.

Complete price listings are given in Table Three of the five rabbits having abraded skin developed a well-defined but transitory erythema on day two of the study. Section 4 - First Aid Measures Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Neurotoxicity: No data available. Environmental Exposure Factors A. Acute Toxicity The acute toxicity of a chemical substance refers to the adverse physiologic effects produced by single dose exposure. Toxicity to Amphibians 4. Benzotriazole may also be in the monobath chemical packet whose contents coats the negative and receiving layers during processing of dye diffusion processes, where its presence is said to have a great effect on the quality of the color image Loznevoi et al. Acute Inhalation Toxicity A report on the inhalation toxicity of benzotriazole to rats indicated that the substance may present a severe respiratory hazard Sherwin-Williams Company, Minimize dust generation and accumulation. Acute Dermal Toxicity Investigations conducted by the Sherwin-Williams Company indicated that neither benzotriazole nor tolyltriazole is significantly toxic to rabbits by dermal exposure. Avoid breathing dust. Velox and Velox Premier papers manufactured by Eastman Kodak Company, widely used in large mass pro- duction commercial photofinishing operations, are examples of well-known blue- black emulsions which almost certainly contain benzotriazole. Nevertheless, it is recommended that, in accord- ance with good industrial practice, unnecessary personal contact with these chemicals be avoided. Bromide ion is therefore more correctly viewed as a development restrainer than an antifoggant. In the case of biodegradable plastics with water soluble UV protective coatings, the stabilizers get into the environ- ment sooner rather than later. The product at this point is of relatively high purity, but may be further purified, if necessary, by recrystallization from a different solvent, such as benzene. In all cases, the rabbits were completely free of adverse skin reactions edema or erythema resulting from the chemical exposure. Benzotriazole and alkylbenzotriazoles have also been recommended in the formulation of dishwater detergents Ciba-Geigy, a. From Disposal 87 6. Screening results are presented in Table 20 and demonstrate that benzotriazole was found to be tumor inhibitory against Ca Regulatory information The general trend shown in the table is towards importing increasing amounts of these compounds. It does not represent any guarantee of the properties of the product. Stability and reactivity Scoop up with a nonsparking tool, then place into a suitable container for disposal. Pick up and arrange disposal. Experimental evidence is not available, however, to support this theory. Only very limited subacute toxicity data are available concerning the benzotriazole derivatives. In later studies conducted by Adler and Albert , benzotriazole was investigated for pharmacologic action because of its struc- tural relationship to naturally occurring indole derivatives. Thus, the following compounds behave similarly with respect to preventing the corrosion of copper: benzotriazole, 4-, 5-, 6-, or 7-methylbenzotriazole, 4-, 5-, 6-, or 7-chlorobenzotriazole, and nap- thotriazole. Treatment was made six days per week for four weeks. Intramolecular hydrogen bonding in the Tinuvins is the key to their effectiveness as UV stabilizers. Lund and Kwee attribute the reduction of benzotriazole in acidic solution to a four electron mechanism whose final product is o-aminophenylhydrazine: H While the polarographic data in this work was not gathered specifically in order to develop analytical techniques for the molecules studied, it demonstrates that polarography is a feasible technique for the benzotriazole derivatives investi- gated. Subacute Toxicity e. The product is also high in purity. Avoid breathing vapours, mist or gas. The ions of zinc, lead, copper, cobalt, nickel, and iron do not interfere. In summary, it is clear that the question of the exact mode of action of this and other similar antifoggants is far from settled. Provide appropriate exhaust ventilation at places where dust is formed. A UV absorber such as Tinuvin and an antioxidant are also added to prevent breakdown of the lacquer under the influence of UV radiation. Autoignition Temperature: Not available. From Use In anticorrosion applications, benzotriazoles have little oppor- tunity to contaminate the environment, except by slow leaching or migration processes. Other transition metals form stable complexes with benzotriazole. In all of these applications, benzotriazole is used with other inhibitors. The lack of cross-interferences in these methods suggests their use in a number of applications, including mining and effluent analysis. The compounds were administered orally to four groups of ,ten rats five male and five female which were observed for 14 days after treatment. If victim is conscious and alert, give cupfuls of milk or water. In spite of the amount of attention these compounds have received in photochemical studies, it appears that 1-substltuted benzotriazoles are not particularly important commercial materials. The results, summarized in Table 28, indicate that compounds 2 and 3, which were not inhibitory at the two-cell stage, in- hibited the neurula very strongly.
