In vitro study | Cetylpyridinium chloride (CPC), as the active ingredient of antibacterial mouthwash, has broad-spectrum antibacterial activity and rapid bactericidal effect on Gram-positive bacteria, especially on yeast. A 0.05% concentration of PCP as a mouthwash resulted in an immediate reduction in bacterial numbers from 2.0 log steps to 2.5 log steps(> amp; Gt; 99%). After 1 hour of use, the number of bacteria will return to 1 log step (= 90%). CPC is able to inhibit plaque, thereby reducing gingivitis. Compared with chlorhexidine, CPC has a lower residual effect, so it has a weaker effect on plaque and gingivitis. CPC has definite curative effect on oropharyngeal candidiasis. In dental clinics, CPC mouthwash can significantly reduce infectious aerosols, thereby protecting staff and patients. Even in the case of prolonged use of CPC (up to 6 weeks), the balance of the flora in the oral cavity is not disturbed. |
In vivo study | Cetylpyridinium chloride increases the risk of severe allergic reactions such as swelling of the mouth, face, lips or tongue, difficulty breathing, rash and hives. Ingestion of high concentrations of Cetylpyridinium chloride can cause lung injury. Cetylpyridinium chloride is toxic if swallowed or inhaled. |

introduction | decadecane pyridine chloride is a cationic quaternary ammonium compound, and it is also a very important surface activity and fungicide in life. Under the same conditions of use, the killing rate of heterotrophic bacteria, iron bacteria and sulfate unwilling bacteria is better than that of dodecyl dimethyl benzyl ammonium chloride, dodecyl dimethyl benzyl ammonium bromide and other commonly used quaternary ammonium salt fungicides. |
biological activity | Cetylpyridinium chloride is a cationic quaternary ammonium compound as an oropharyngeal disinfectant. |
use | antiseptic. |
Production method | In a mixture of 48mlSOCl 2 and 0.3gHCON(CH 3) 2, the temperature is controlled at 30-35°C under stirring, and 81g of decanol is dropped. After dropping, the mixture is boiled for 30min, cooled, and distilled to obtain a fraction of 138-140 ℃ (pressure 270Pa), which is chlorodecane with 92.2% yield. 80g of chloropetane and 32g of dry pyridine were heated to 150-160 ℃ in an oil bath, reacted for 12-15h, after the reaction, 80ml of dry acetone was added, and the mixture was heated and dissolved in a water bath before cooling to obtain a product with 994% yield. The melting point is 87-88 ℃. |
