C.I. Solvent yellow 14: Does not have an individual approval but may be used under an appropriate group standard

C.I. SOLVENT YELLOW 14 is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. This chemical is incompatible with strong oxidizing agents and strong acids (NTP, 1992).

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SMALL SPILLS AND LEAKAGE: If a spill of this chemical occurs, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with acetone and transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the adsorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with a combination filter cartridge, i.e. organic vapor/acid gas/HEPA (specific for organic vapors, HCl, acid gas, SO2 and a high efficiency particulate filter). (NTP, 1992)

SKIN SENSITIVITY OF RED 225 & ITS IMPURITIES DETERMINED BY PATCH TEST. COMMERCIAL PREPN SHOWED POSITIVE REACTIONS IN ALL 6 SUBJECTS. SUDAN I ISOLATED & IDENTIFIED. SUDAN I ALSO SHOWED POSITIVE REACTIONS IN ALL 6 SUBJECTS.

Most organic azo dyes are potential skin sensitizers, the most important of which are paraphenylenediamine and its analogs. Water soluble azo dyes are more likely to cause clinical sensitization than insoluble dyes. ... In addition to allergic eczematous contact dermatitis, color developing solutions have caused lichen planus like eruptions. /Organic dyes/

"Kumkums" are colored cosmetics frequently applied to the center of the forehead by Hindu women. Pigmented allergic contact dermatitis to "kumkum" was reported recently. It was associated with Brilliant Lake Red R and Sudan I allergy. These might be the causitive allergens. Three of 7 brands of red "kumkums" analyzed by gas chromatography-mass spectrophotometry were found to contain various concentrations of Sudan I. They ranged from 2.789 mg/g to 8.694 mg/g. Sudan I is probably the cause of pigmented allergic contact dermatitis in red "kumkum".

A carcinogenesis bioassay of C.I. solvent Yellow 14 (94.1% pure), a widely used monoazo dye, was conducted by feeding diets containing 250 or 500 ppm of C.I. Solvent Yellow 14 to groups of 50 F344 rats of either sex for 103 weeks. Similar groups of 50 B6C3F1 mice received diets containing 500 or 1,000 ppm of C.I. Solvent Yellow 14 for 103 weeks. Groups of 50 untreated rats and mice of either sex served as controls. Throughout the bioassay, mean body weights of dosed rats and mice were slightly lower than those of controls. No compound-related clinical signs or effects on survival were observed. Increases in nonneoplastic lesions included cardiac valve fibrosis for male and female rats, lymphoid hyperplasia of the lung for male rats, and for female rats, bile duct hyperplasia, focal atrophy of the pancreatic acinus, and nephropathy. None of these effects were observed in mice. Under the conditions of this bioassay, C.I. Solvent Yellow 14 was carcinogenic in male and female F344/N rats, as evidenced by increaed incidences of neoplastic nodules of the liver. C.I. Solvent Yellow 14 was not carcinogenic for B6C3F1 mice of either sex.

Sudan I activated by pre-incubation with microsomal enzymes of rat livers covalently binds to DNA from calf thymus. Benzenediazonium ion formed from Sudan I by activation with microsomal enzymes is the principal active metabolite, which binds to DNA. Enzymatic hydrolysis of modified 14(C)-labelled DNA, followed by separation of deoxynucleosides on a Sephadex G-10 column revealed that deoxyguanosine is the principal target for the binding of activated Sudan I.
