Formaldehyde, 10%, Buffered
Formaldehyde is a colorless hazardous gas produced by the oxidation of methanol and utilized in laboratory applications as an antiseptic, disinfectant, histologic fixative, and general-purpose chemical reagent. Methanal, methylene oxide, oxymethyline, methyl aldehyde, and oxomethane are some of its other names. Formaldehyde 10% in water solution, is used as a disinfectant and to preserve biological specimens. Formaldehyde 10% Buffered is highly suited for high-throughput laboratories owing to its brief fixing time, but it can also be utilized for long-term tissue storage. Biologically, it has been found that Formalin fixation develops between the aldehydes and the proteins leading to a gel that preserves the in vivo interaction of cellular elements.
Formaldehyde is a naturally occurring organic compound with the formula CH₂O. It is the simplest of the aldehydes. The common name of this substance comes from its similarity and relation to formic acid. Formaldehyde is an important precursor to many other materials and chemical compounds. Read more here.
Formaldehyde is readily soluble in water and is commonly distributed as a 37% solution in water; formalin, a 10% solution of formaldehyde in water, is used as a disinfectant and to preserve biological specimens. Formaldehyde, solutions (formalin) (corrosive) appears as a colorless liquid with a pungent irritating odor. Read more here.
More Information About Formaldehyde
How Dangerous Is Formaldehyde? Aside from ALS risk or other nervous system consequences, formaldehyde is a respiratory irritant that causes chest pain, shortness of breath, coughing, and nose and throat irritation, according to the ATSDR. It can also cause cancer, and has been linked to an increased risk of asthma and allergies in kids. Read more here
37% Formaldehyde Solution Uses
37% Formaldehyde Solution is used in the U.S. poultry industry as a disinfectant on poultry farms, in brooder houses, hatcheries and hatchery vehicles. It reduces contamination levels caused by bacteria, viruses and molds throughout the production process. Using formaldehyde as the primary disinfection agent controls key organisms, such as Salmonella, Pseudomonas, Proteus, E. coli, H.capsulatum, Staphylococcus, Streptococci and Aspergillus.
Information On Formaldehyde From PubChem
Formaldehyde is a colorless poisonous gas synthesized by the oxidation of methanol and used as an antiseptic, disinfectant, histologic fixative, and general-purpose chemical reagent for laboratory applications. Formaldehyde is readily soluble in water and is commonly distributed as a 37% solution in water; formalin, a 10% solution of formaldehyde in water, is used as a disinfectant and to preserve biological specimens. Environmentally, formaldehyde may be found in the atmosphere, smoke from fires, automobile exhaust and cigarette smoke. Small amounts are produced during normal metabolic processes in most organisms, including humans. At room temperature, formaldehyde is a colorless, flammable gas that has a distinct, pungent smell. It is also known as methanal, methylene oxide, oxymethyline, methylaldehyde, and oxomethane. Formaldehyde is naturally produced in small amounts in our bodies. It is used in the production of fertilizer, paper, plywood, and urea-formaldehyde resins. It is also used as a preservative in some foods and in many products used around the house, such as antiseptics, medicines, and cosmetics. Formaldehyde, solutions (formalin) (corrosive) appears as a colorless liquid with a pungent irritating odor. Contains 37-50% formaldehyde by mass and varying amounts of methanol, added to prevent precipitation of formaldehyde polymers (formaldehyde exists in solution as CH2(OH)2 and its polymers HO(CH2O)xH where x averages about three). Formalin free of methanol is also shipped but must be kept warm (about 30°C (86°F)) to prevent polymerization. Pure formaldehyde, a gas, is not handled commercially because it tends to polymerize exothermally and may ignite. Vapor from formalin solution is flammable and an explosion hazard when exposed to flame or heat. Skin and eye irritant. Confirmed carcinogen.
Formaldehyde Safety And Hazards Information From PubChem
Exposure Routes: inhalation, skin and/or eye contact Symptoms: Irritation eyes, nose, throat, respiratory system; lacrimation (discharge of tears); cough; wheezing; [potential occupational carcinogen] Target Organs: Eyes, respiratory system . The probable oral lethal dose for humans is 0.5-5 g/kg, or between 1 ounce and 1 pint for a 150 pound person. Acute -- below 1 ppm, odor perceptible to most. 2-3 ppm, mild tingling of eyes. 4-5 ppm, increased discomfort, mild lacrimation. 10 ppm, profuse lacrimation; can be withstood only for few minutes. 10-20 ppm, breathing difficult, cough, severe burning of nose and throat. 50-100 ppm, acute irritation of respiratory tract, very serious injury likely. Skin -- primary irritation from strong solutions, gas. Delayed -- sensitization dermatitis. Suspected carcinogen. Effects in women include menstrual disorders and secondary sterility. Solutions splashed in eyes have caused injuries ranging from severe, permanent corneal opacification and loss of vision to minor discomfort. In people sensitized to formaldehyde, late asthmatic reactions may be provoked by brief exposures at approximately 3 ppm.
Formaldehyde can be found naturally in food up to the levels of 300 to 400 mg/kg, including fruits and vegetables (e.g. pear, apple, green onion), meats, fish (e.g., Bombay-duck, cod fish), crustacean and dried mushroom, etc. Ingestion of a small amount of formaldehyde is unlikely to cause any acute effect.

Formaldehyde Poisoning is a disorder brought about by breathing the fumes of formaldehyde. This can occur while working directly with formaldehyde, or using equipment cleaned with formaldehyde. Major symptoms may include eye, nose, and throat irritation; headaches; and/or skin rashes. Read more here.
Formaldehyde (systematic name methanal) is a naturally occurring organic compound with the formula CH2O (H−CHO). It is the simplest of the aldehydes (R−CHO). The common name of this substance comes from its similarity and relation to formic acid. Formaldehyde is an important precursor to many other materials and chemical compounds. In 1996, the installed capacity for the production of formaldehyde was estimated at 8.7 million tons per year. It is mainly used in the production of industrial resins, e.g., for particle board and coatings. In view of its widespread use, toxicity, and volatility, formaldehyde poses a significant danger to human health. In 2011, the US National Toxicology Program described formaldehyde as "known to be a human carcinogen". Read more here.

Great just what we needed
I purchased this product to use as a fixative in the preservation of hearts from small animals (squirrel, skunk, fox, etc). I have only done 4 preservations (formalin, then alcohol) thus far, but so far so good.
