  • Signal Word:no data available

  • Hazard Statement:no data available

  • First-aid measures: General adviceConsult a physician. Show this safety data sheet to the doctor in attendance.If inhaled If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician. In case of skin contact Wash off with soap and plenty of water. Consult a physician. In case of eye contact Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician. If swallowed Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician. /SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. 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/

  • Fire-fighting measures: Suitable extinguishing media Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Wear self-contained breathing apparatus for firefighting if necessary.

  • Accidental release measures: Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8. Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Accidental Release Measures. Personal precautions, protective equipment and emergency procedures: Avoid dust formation. Avoid breathing vapours, mist or gas. Environmental precautions: Do not let product enter drains. Methods and materials for containment and cleaning up: Sweep up and shovel. Keep in suitable, closed containers for disposal.

  • Handling and storage: Avoid contact with skin and eyes. Avoid formation of dust and aerosols.

SINGLET OXYGEN REACTIONS IN AQUEOUS SOLUTION. PHYSICAL AND CHEMICAL QUENCHING RATE CONSTANTS OF CROCIN AND RELATED CAROTENOIDS

Manitto, Paolo,Speranza, Giovanna,Monti, Diego,Gramatica, Paola

, p. 4221 - 4224 (2007/10/02)

Thermal decomposition of 3-(1,4-epidioxy-4-methyl-1,4-dihydro-1-naphthyl)propionic acid (2) has been used to measure both the physical and chemical quenching rate constants of 1O2 (kQ and kR, respectively) by water-soluble 8,8'-diapocarotenoids such as crocin (1a) and its derivatives (1b,c).The value of kQ was found to be slightly lower than the diffusion controlled rate constant in all the solvents examined, whereas kR showed strong dependence on the medium, going from ca. 108 in H2O to 106 M-1s-1 in DMF and DMSO.These findings suggest that both energy- and electron-transfer mechanisms are involved in the quenching of O2 (1Δg) by crocinoids.

13-cis-Crocin: A new Crocinoid of Saffron

Speranza, Giovanna,Dada, Giuseppe,Manitto, Paolo,Monti, Diego,Gramatica, Paola

, p. 189 - 192 (2007/10/02)

A new crocinoid isolated from saffron was shown to be a stereoisomer of crocin, i.e. 13-cis-crocin.In the light of this finding, the old question of the natural occurrence and structure of neocrocins in saffron is discussed.
