Cobaltous arsenate

== Description ==
A pale to medium violet pigment. Cobaltous arsenate, or light cobalt violet, occurs in nature as cobalt bloom or erythrite. Once it was synthetically produced in 1880, it became an important permanent, violet pigment. Cobaltous arsenate is now rarely used because of its toxicity. It has been replaced by the use of cobaltous phosphate and cobaltous ammonium phosphate. Cobaltous arsenate was used as a colorant in paints, glass, glazes, and enamels.

Cobaltous oxide

== Description ==
A dark gray crystalline powder. Cobaltous oxide was obtained by roasting native cobalt ores (cobaltite, smaltite). Commonly called zaffre, it is used to manufacture smalt, a blue pigment. Smalt is the fused product of finely ground zaffre mixed with potassium silicate (glassmakers fine white sand). In Europe, zaffre was used as early as the 14th century as a pigment for paints, glazes and glass. Cobalt oxide is used to give a blue color to structural glass, bottles, and optical filter glasses. It is also used to minimize the yellow tint from iron impurities in window glass.

Cochineal (Dactylopius coccus) LC

== Description ==
The cochineal is a scale insect in the suborder Sternorrhyncha, from which the natural dye carmine is derived. Cochineal lives on catcti in the genus Opuntia. Cochineal is native to tropical and subtropical South America as well as Mexico and Arizona. These insects are brushed off and dried for storage. 
The insect produces carminic acid that deters predation by other insects. Carminic acid, typically 17-24% of dried insects' weight, can be extracted, then mixed with aluminium or calcium salts to make carmine dye.

HPLC-DAD-MS analysis was performed with an Agilent 1100 liquid chromatography system consisting of an automatic injector, a gradient pump, a HP series 1100 DAD, and an Agilent series 1100 VL on-line atmospheric pressure ionization electrospray ionization mass spectrometer. Separations were done on a Vydac 214TP52 analytical column (2.1 mm diameterX250 mm; 5-ím particle size). The column was eluted at a flow rate of 0.2 mL/min with a tertiary gradient of water (A),acetonitrile (B), and 1% (v/v) aqueous formic acid (C) with the following elution program: 0 min, 90% A, 5% B, 5% C; 0-55 min, a linear gradient to 35% A, 60% B, 5% C; 55-60 min, a linear gradient elution to 15% A, 80% B, 5% C; 60-62 min, isocratic elution at 15% A, 80% B, 5% C; 62-70 min gradient elution to 90% A, 5% B, 5% C; and reequilibration with the latter solvent for 15 min. The mass spectrometer was run both in the negative and positive ion mode.

Cockroach

== Description ==
General name for flat, oval-shaped brown insects of the family Blattidae. They are common household pests and can grow to 9 cm long. Cockroaches are nocturnal and sensitive to light. They have highly sensitive antennae that enable them to detect tiny amounts of food and moisture. Their ability to sense air movements allows them to flee from danger. Both the nymphs and adults feed on almost anything, such as starchy, sugary, and proteinaceous foods. They will eat cloth that is sized with starch or glue. Common desiccating powders such as boric acid, Dri-die and sulfur are used along with pesticides to exterminate cockroaches. Pyrethrin powder is also commonly used but it is most effective as an attractant and knock-down agent, not as as insecticide. 
See also American cockroach, brown banded cockroach, German cockroach and oriental cockroach.
== Risks ==
Can produce surface erosion on many types of materials
