SRP: Criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

The Food and Drug Administration (FDA) is revising its requirements for cochineal extract and carmine by requiring their declaration by name on the label of all food and cosmetic products that contain these color additives. This final rule responds to reports of severe allergic reactions, including anaphylaxis, to cochineal extract- containing food and carmine-containing food and cosmetics and will allow consumers who are allergic to these color additives to identify and thus avoid products that contain these color additives. This action also responds to a citizen petition submitted by the Center for Science in the Public Interest (CSPI).

Flash point data for this compound are not available. It is probably combustible. (NTP, 1992)

Not Classified

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)

SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces 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. STORAGE PRECAUTIONS: You should store this material at ambient temperatures. (NTP, 1992)

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

Toxicity

Carminic acid occurs as a glucosidal coloring matter from the scale insect Coccus cacti L., Homoptera (cochineal)(1).

Carminic acid's production and use as a colorant in cosmetics(1) and as pigments and stains in photography and chemistry applications(2) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 440(SRC), determined from a structure estimation method(2), indicates that carminic acid is expected to have moderate mobility in soil(SRC). The pKa values of carminic acid are 2.81, 5.43 and 8.10(3), indicate that this compound will almost entirely exist in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization from moist soil is not expected because the acid exists as an anion and anions do not volatilize(SRC). Carminic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 5.07X10-27 mm Hg at 25 °C(SRC), determined from a fragment constant method(5). Biodegradation data in soil were not available(SRC, 2010).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 440(SRC), determined from a structure estimation method(2), indicates that carminic acid is expected to adsorb to suspended solids and sediment(SRC). The pKa values of 2.81, 5.43 and 8.10(3) indicate carminic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(SRC). According to a classification scheme(4), an estimated BCF of 3.2(SRC), from an estimated log Kow of 0.97(5) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation data in water were not available(SRC, 2010).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), carminic acid, which has an estimated vapor pressure of 5.07X10-27 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase carminic acid may be removed from the air by wet or dry deposition(SRC). Carminic acid contains chromophores that absorb at wavelengths >290 nm(3), and therefore may be susceptible to direct photolysis by sunlight(SRC); its UV absorption maxima is approximately 500 nm in water(4) and primary aliphatic alcohols(5).

Carminic acid is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(1). Carminic acid contains chromophores that absorb at wavelengths >290 nm(1), and therefore may be susceptible to direct photolysis by sunlight(SRC). Carminic acid's UV absorption maxima in water is 500 nm(2); in primary aliphatic alcohols (methanol, ethanol, 1-propanol, 1-butanol, 1-hexanol and 1-octanol) the absorption maxima was measured as 496 nm(3).

An estimated BCF of 3.2 was calculated in fish for carminic acid(SRC), using an estimated log Kow of 0.97(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of carminic acid can be estimated to be 440(SRC). According to a classification scheme(2), this estimated Koc value suggests that carminic acid is expected to have moderate mobility in soil. The pKa values of carminic acid are 2.81, 5.43 and 8.10(3), indicating that this compound will almost entirely exist in anion form the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).

The pKa values of 2.81, 5.43 and 8.10(1) indicate carminic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(SRC). Volatilization from moist soil is not expected because the acid exists as an anion and anions do not volatilize(SRC). Carminic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 5.07X10-27 mm Hg(SRC), determined from a fragment constant method(2).

Occupational exposure to carminic acid may occur through dermal contact with this compound at workplaces where carminic acid is produced or used. Use data indicate that the general population may be exposed to carminic acid via ingestion of food and beverages containing carminic acid dyes, and dermal contact with cosmetic products containing carminic acid.

Drug Information

Chemicals and substances that impart color including soluble dyes and insoluble pigments. They are used in INKS; PAINTS; and as INDICATORS AND REAGENTS. (See all compounds classified as Coloring Agents.)|Natural or synthetic dyes used as coloring agents in processed foods. (See all compounds classified as Food Coloring Agents.)

The food coloring carminic acid redox cycles to produce free radicals. These radicals, in the presence of trace amounts of iron salts, readily damage membrane lipid and degrade the carbohydrate deoxyribose. Damage to membrane lipid appears to involve mainly organic oxygen radicals such as alkoxy and peroxy radicals, whereas that to deoxyribose implicates the hydroxyl radical formed in a Fenton-type reaction. Antioxidants and iron chelators prevent such damage.|The antitumor agent carminic acid did not bind to DNA but nicked it slowly, more rapidly when reduced in situ, & still more when prereduced at the quinone moiety.

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. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)
