Non-flammable, combustible when exposed to open flames and high heat.
Toxicological data
1. Skin irritation: Glutaraldehyde is irritating to the skin and mucous membranes of humans and animals. 5% glutaraldehyde can cause severe irritation symptoms, but 2% glutaraldehyde only stains the skin a shiny brown color.
2. Systemic toxicity: Glutaraldehyde has mild systemic toxicity in humans.
3. Acute toxicity: 2% fortified acidic glutaraldehyde. Mouse vein: LD5026±1.6mg/Kg. Death time is 4 days; rat vein: LD5024±2mg/Kg Death time 0~2 days; oral administration to mice: LD50 298±25mg/Kg Death time.Film hardening agent for picture tubes. This product is used to produce the central stimulant drug Lobelia hydrochloride. Glutaraldehyde is a fast-acting and broad-spectrum chemical sterilant. A low-concentration glutaraldehyde aqueous solution can show activity against many microorganisms at room temperature, and is pathogenic against reproductive bacteria, viruses, and mycobacteria. Molds and bacterial spores have a high sterilizing effect and are very toxic to humans. Some people say that formaldehyde was used at the beginning of this century, and chemical disinfectants such as ethylene oxide were used in the 1930s. Glutaraldehyde is currently the third milestone. In 1973, the World Health Organization (WHO) recommended the third product as a disinfectant for hepatitis B virus. Among known aldehydes, glutaraldehyde is the best protein cross-linking agent. The characteristics of cross-linking are high activity, fast reaction, high binding capacity, stable product, and strong resistance to boiling water, acid, and enzymes. Therefore, Leather tanned with glutaraldehyde has excellent properties such as sweat resistance, heat resistance, and soaping resistance.
2.In oil field chemicals, it can be used as water Biocides for base oil well fracturing fluids, cross-linking agents for cellulose, etc. As a water treatment bactericide, glutaraldehyde can be widely used in the sterilization of circulating water systems. It can effectively control the number of microorganisms in various water systems and effectively peel off biological slime and biofilm. The input amount is generally 50 to 100mg/L. . It has the advantages that quaternary ammonium salt series fungicides cannot match. It does not foam, is easy to use, and has good compatibility with corrosion inhibitors.In actual use, glutaraldehyde is often used Use in combination with other chemicals such as quaternary ammonium salts.
3.Use As a water treatment bactericide, it can be widely used in the sterilization of circulating water systems. It can effectively control the number of microorganisms in various water systems and effectively strip off biological slime and biofilm. . It does not foam, is easy to use, and has good compatibility with corrosion inhibitors. The dosage is generally 50~100mg/L. It can be combined with chromium for tanning leather.
