Cetylpyridine chloride destroys harmful bacteria.
Cetylpyridinium chloride (CPC) is a chemical that destroys or cleans harmful bacteria from organic surfaces. It is often found in various oral sprays, mouthwashes, and lozenges, as well as other types of surface disinfectants. The human throat, nostrils, and mouth are lined with mucous membranes, which can absorb a host of potentially dangerous germs, chemicals, and viruses. An antiseptic such as cetylpyridinium chloride can penetrate mucous membranes and potentially inhibit the growth and spread of these infectious substances.
Some bathroom cleaners and surface disinfectants contain cetylpyridinium chloride.
Microorganisms that irritate and multiply in moist tissues are usually airborne, although they can be transmitted through contact with various foods, drinks, or items placed in the mouth or nose, such as straws or fingers. Symptoms of a mucous membrane infection often include swelling, discoloration, or an unpleasant odor. In the mouth and nose, these symptoms can also manifest as plaque on the teeth, gingivitis around the gums, sore throat, or sinusitis.
Small amounts of cetylpyridinium chloride are often found in oral products such as toothpaste.
CPC uses lymph, the fluid between cells, to travel through the layers of the skin and across the membranes of smaller infectious organisms, which have fewer cells than human tissue. In small doses, cetylpyridinium chloride, along with other chemicals, can kill harmful bacteria without causing permanent damage to affected tissue. Small amounts of this chemical are often included in many oral care products, including mouthwashes, toothpastes, lozenges, and various sore throat sprays.
Small amounts of CPC can be found in medications used to treat sore throats.
It is not uncommon for rashes, skin irritation, nausea, or bleeding to occur when CPC is used in large amounts. Many symptoms of cetylpyridinium chloride overexposure may reflect symptoms of the bacteria that initially infected the area. Other examples of possible damage may include brown discoloration of the teeth, epidermal swelling in areas exposed to the chemical, prolonged numbness, burning sensation, and difficulty breathing. Other much more serious symptoms can include ulcers in the mouth or throat, permanent lung damage, seizures, and paralysis.
A variety of sprays that treat sore throats may contain small amounts of cetylpyridinium chloride.
In its purest form, cetylpyridinium chloride is a tasteless, odorless, fine white powder that can be fatal if inhaled or ingested. In addition to its toxicity, the chemical is combustible and should be kept away from heat sources or areas where sparks could occur. Some cleaners, shampoos, and fabric softeners may also contain CPCs. To properly handle any product that contains CPCs, always read and follow the instructions on the package. Gloves or masks should be worn to prevent or minimize skin contact when indicated.
