Cetylpyridinium chloride (CPC) is a cationic quaternary ammonium compound used in some types of mouthwashes, toothpastes, lozenges, throat sprays, breath sprays, and nasal sprays. It is an antiseptic that kills bacteria and other microorganisms. It has been shown to be effective in preventing dental plaque and reducing gingivitis. It has also been used as an ingredient in certain pesticides. Cetylpyridinium chloride may cause brown stains between the teeth and on the surface of teeth. However, these stains can be easily removed by a dental hygienist during a routine check-up.

用途

消毒防腐药。

1.是一种阳离子季铵盐，主要通过改变细胞膜的渗透性来达到杀菌的效果，不会产生耐药性
2.在pH4~10之间对广泛的革兰氏阳性和革兰氏阴性细菌都有效，具有广谱杀菌的效果。
3.与常用的阴离子类聚合物，如聚丙烯酸钠完全互溶；卡波类的阴离子聚合物预先用少量增溶剂增溶的情况下也可得完全透明体系；AES体系中，无需增溶剂即可完全溶解形成透明体系。
广谱杀菌、抗静电、抗粉刺、去屑、美白、除臭、防腐。
应用：面膜、湿纸巾、漱口水、护肤霜、除菌皂、洗发香波、唇膏、除臭产品、女性护理液等。
