Glutaral

Johnson and johnson brand OF glutaral

C5H8O2 (100.0524)


Glutaral is used as an antimicrobial agent in sugar mills and as a fixing agent in the immobilisation of glucose isomerase enzyme preparations for use in the manufacture of high fructose corn syrup. It is a polymerized isomer of glutaraldehyde known as polycycloglutaracetal used as a fertilizer for aquatic plants. It is claimed that it provides a bioavailable source of carbon for higher plants that is not available to algae. Though not marketed as such due to federal regulations, the biocidal effect of glutaraldehyde kills most algae at concentrations of 0.5 - 5.0 ppm. These levels are not harmful to most aquatic fauna and flora. Adverse reactions have been observed by some aquarists at these concentrations in some aquatic mosses, liverworts, and vascular plants. Glutaraldehyde is a colorless liquid with a pungent odor used to disinfect medical and dental equipment. It is also used for industrial water treatment and as a chemical preservative. Glutaraldehyde is an oily liquid at room temperature (density 1.06 g/mL), and miscible with water, alcohol, and benzene. It is used as a tissue fixative in electron microscopy. It is also employed as an embalming fluid, is a component of leather tanning solutions, and occurs as an intermediate in the production of certain industrial chemicals. Glutaraldehyde is frequently used in biochemistry applications as an amine-reactive homobifunctional crosslinker. The oligomeric state of proteins can be examined through this application. However, it is toxic, causing severe eye, nose, throat and lung irritation, along with headaches, drowsiness and dizziness.

Ethyl acrylate is found in pineapple. Ethyl acrylate is a flavouring ingredient Although there are some reports claiming that ethyl acrylate is a carcinogen, major respected bodies regard the evidence of human carcinogenicity as weak and/or inconsistent. The International Agency for Research on Cancer stated, "Overall evaluation, Ethyl acrylate is possibly carcinogenic to humans (Group 2B)." The United States Environmental Protection Agency (EPA) states, "Human studies on occupational exposure to ethyl acrylate have suggested a relationship between exposure to the chemical(s) and colorectal cancer, but the evidence is conflicting and inconclusive. In a study by the National Toxicology Program (NTP), increased incidences of squamous cell papillomas and carcinomas of the forestomach were observed in rats and mice exposed via gavage (experimentally placing the chemical in the stomach). However, the NTP recently determined that these data were not relevant to human carcinogenicity and removed ethyl acrylate from its list of carcinogens." (Occupational exposure generally involves exposure that occurs regularly, over an extended period of time). Ethyl acrylate is an organic compound primarily used in the preparation of various polymers. It is a clear liquid with an acrid penetrating odor. The human nose is capable of detecting this odor at a thousand times lower concentration then is considered harmful if continuously exposed for some period of time.
