Description
Technical Field
The invention belongs to the field of daily chemical disinfection and sterilization, and particularly relates to a composition beneficial to the stability of a PCMX (prestressed concrete cylinder pipe) degerming liquid and the degerming liquid containing the PCMX.
Background
The sterilization products are widely used, wherein the sterilization agent p-chlorom-xylenol (PCMX) has low toxicity and good sterilization and bacteriostasis capability, and is widely used in the sterilization products. PCMX is poorly soluble in water and in organic solvents such as isopropanol and ethanol. The current general technical method is to add castor oil soap and solvents such as terpineol, ethanol or isopropanol into the formulation of the degerming product to form a relatively stable PCMX aqueous solution. However, when the sterilized product is stored for a long time or when the temperature is changed, the stability of the system is challenged, and problems of high-temperature delamination or low-temperature precipitation occur. The prior technical proposal for solving the stability of the PCMX aqueous solution is to add a large amount of non-aqueous solvent, thereby increasing the cost and material consumption of the degerming product.

Preferably, the fatty acid salt comprises castor oil soap. Further, the mass percentage of the castor oil soap in the fatty acid salt is 70-100%. The castor oil soap comprises castor oil potassium soap, castor oil sodium soap, castor oil magnesium soap and castor oil monoethanolamine soap, wherein the castor oil potassium soap is preferred.
Preferably, the fatty acid salt further comprises oleate. Further, the mass percentage of the oleate in the fatty acid salt is 0-30%. The oleic acid soap comprises oleic acid potassium soap, oleic acid sodium soap, oleic acid magnesium soap and oleic acid monoethanolamine soap, wherein oleic acid potassium soap is preferred.
Further preferably, the mass ratio of the ricinoleic acid amide polyoxyethylene ether to the fatty acid salt is preferably 1:5.
preferably, the composition is prepared as follows: 1) Uniformly mixing 1/3 part of ricinoleic acid amide polyoxyethylene ether and fatty acid salt; 2) Adding water with the formula amount into the mixture obtained in the step 1), and stirring until the water is completely dissolved; 3) Adding the rest 2/3 parts of ricinoleic acid amide polyoxyethylene ether into the step 2), and uniformly mixing.
In order to achieve the second purpose, the invention adopts the following technical scheme:
the PCMX-containing antibacterial solution comprises PCMX and also comprises the composition, wherein the mass percentage of the composition is 5-18%.
Preferably, the mass ratio of PCMX to the composition is 0.2-0.5:1.
compared with the prior art, the invention has the following advantages:
1, the ricinoleic acid amide polyoxyethylene ether and the fatty acid salt are compounded, and compared with the fatty acid salt single surfactant, the HLB value of the composition is optimized. When the composition is applied to a sterilization liquid containing PCMX, the composition helps to establish a stable PCMX solution system, further helps to reduce the dosage of solvents such as isopropanol, terpineol and the like, improves the green of the product and has good economic value.
2, compared with fatty acid salt, the composition can help the stability of PCMX at a lower dosage, reduce the content of castor oil double bonds in the system, and reduce the problem of discoloration of the sterilizing liquid caused by oxidation of the castor oil double bonds.
The invention is described in detail below for a better understanding and implementation.
