Composition of phthalyl diformaldehyde disinfectant

Abstract

A composite disinfectant is prepared from phthalic aldehyde, non-ionic surfactant, amphoteric ionic surfactant, cationic surfactant, pH value regulator and water to distilled water. Its advantages are broad spectrum, no irritation and odor, quickly taking its effect, high safety, and no corrosion to steel.

Description

technical field

[0001] The invention relates to a chemical disinfectant, in particular to a phthalaldehyde disinfectant composition. Background technique

[0002] Existing high-efficiency chemical disinfectants are limited in terms of sterilization of metal instruments due to their shared toxicity and metal corrosion. For example, peracetic acid has a strong pungent smell and bleaching effect. When the concentration is slightly higher, it is easy to cause skin damage and cannot be used for disinfection of precision instruments and sharp equipment; the activated chlorine dioxide disinfectant has poor stability and cannot be used. More than 24 hours, due to its strong oxidizing properties, it is obviously not suitable for long-term sterilization of endoscopes; ethylene oxide is less safe because of its active chemical properties, flammability, explosion, and toxicity; Due to its strong pungent smell and obvious toxicity, the frequency and scope of formaldehyde application are...

Examples

Embodiment 1

[0017] A kind of o-phthalaldehyde disinfectant composition, the volume weight percentage of its each component is:

[0018] Phthalaldehyde 0.5% Nonylphenol Ethoxylates 0.1-0.2%

[0019] Lauryl Betaine (BS-12) 0.05-0.1%

[0020] 1NNaOH or NaHCO 3 Adjust the pH value to 6.0-7.5

[0021] Distilled water balance

Embodiment 2

[0023] A kind of o-phthalaldehyde disinfectant composition, the volume weight percentage of its each component is:

[0024] Phthalaldehyde 0.5% Nonylphenol Ethoxylate 0.1-0.25%

[0025] 1NNaOH or NaHCO 3 Adjust the pH value to 6.0-7.5

[0026] Distilled water balance

Embodiment 3

[0028] A kind of o-phthalaldehyde disinfectant composition, the volume weight percentage of its each component is:

[0029] Phthalaldehyde 0.5% Nonylphenol Ethoxylates 0.1-0.2%

[0030] Lauryl dimethyl benzyl ammonium chloride (1227) 0.01-0.15%

[0031] 1NNaOH or NaHCO 3 Adjust the pH value to 6.0-7.5

[0032] Distilled water balance

[0033] The high-efficiency o-phthalaldehyde disinfectant of the above-mentioned embodiments 1, 2, and 3 is particularly suitable for the immersion disinfection and sterilization of moisture-resistant and heat-resistant instruments. Through experimental observation, it is compared with the existing 2% glutaraldehyde disinfectant for disinfection and sterilization performance In the test, regardless of its sterilizing effect, bactericidal stability, or other performances, it is more superior. The performance comparison of the two disinfectants is shown in the following table:
