C21H38ClN

Basic Info

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.

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

ALKYLPYRIDINIUM DERIVATIVES ARE LESS BIODEGRADABLE THAN MONOALKYLTRIMETHYL & ALKYLBENZYL DIMETHYL AMMONIUM CHLORIDES. /ALKYLPYRIDINIUM DERIVATIVES/

12.3 Bioaccumulative potential

Whole body BCF values of 21, 22, and 13, were measured for clams, fathead minnows, and tadpoles, respectively, under flow-through conditions over a 7-day period, for a structurally-similar compound, cetylpyridinium bromide(1). An estimated BCF of 2 was calculated for cetylpyridinium chloride(SRC), using a log Kow of 1.71(2) and a regression-derived equation(3). According to a classification scheme(4), these BCF values suggest the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of cetylpyridinium chloride is estimated as 200(SRC), using a measured log Kow of 1.71(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that cetylpyridinium chloride is expected to have moderate mobility in soil. However, quaternary ammonium compounds are known to sorb strongly, and rapidly in well-mixed systems, to a wide variety of materials (such as sewage sludge, sediment, clay)(4) and the mobility of cetylpyridinium chloride in soil may be considerably less than estimated(SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
