Acute inhalation toxicity of cetylpyridinium chloride

Food and Chemical Toxicology, 1991
Cetylpyridinium chloride (CPC) is a quaternary ammonium salt and cationic surfactant. It has been used as a biocide in personal hygiene products and a charge control additive in some reprographic toners. CPC is orally toxic to rats, mice and rabbits and can cause severe eye irritation.

The interaction of amylopectin with cetylpyridinium chloride

Journal of Colloid Science, 1961
Abstract The complex which is formed between amylopectin and cetylpyridinium chloride (CPC) in dilute aqueous NaOH is indicated by a turbidity, measured spectrophotometrically. No significant turbidity is apparent in the absence of any of the components.

Influence of Cetylpyridinium Chloride on Corneal Permeability to Penicillin

Journal of Pharmaceutical Sciences, 1979
The epithelial surface or the deepithelialized anterior stromal surface of isolated rabbit corneas was perfused for 3 hr with 14C-penicillin in 25 mM Ringer-bicarbonate solution with or without 1% albumin and with or without 0.02% cetylpyridinium chloride.

Efficacy of Cetylpyridinium Chloride Used as Oropharyngeal Antiseptic

Arzneimittelforschung, 2011
Cetylpyridinium chloride, (CPC, CAS 123-03-5) as active ingredient of antiseptic oral mouthrinses has a broad antimicrobial spectrum with a rapid bactericidal effect on gram-positive pathogens and a fungicide effect on yeasts in particular. There are gaps in its effectiveness against gram-negative pathogens and mycobacteria.

Bioadhesive Lozenge for the improved Delivery of Cetylpyridinium Chloride

Journal of Pharmaceutical Sciences, 1990
Conventional lozenges produce a high initial release of drug in the oral cavity, which rapidly declines to subtherapeutic levels, and requires multiple daily administration with associated problems of systemic toxicity and compliance. Various multilayer compacts containing cetylpyridinium chloride were evaluated in vitro using release into simulated ...

Spectrophotometric determination of cetylpyridinium chloride in pharmaceutical products

Journal of Pharmaceutical and Biomedical Analysis, 2001
The aim of this work is to study the formation of chelate compound of strontium (Sr(II)) with bromopyrogallol red (BPR) and cetylpyridinium chloride (CPC) and to develop a simple, rapid and sensitive method for spectrophotometric determination of CPC in pharmaceutical products, based on the influence of micellar media on the absorption spectra of the ...

Interaction of Cetylpyridinium Chloride with Giant Lipid Vesicles

Langmuir, 2005
The interaction of cationic surfactant cetylpyridinium chloride, CPC, with giant lipid vesicles prepared from 1-palmitoyl-2-oleoylphosphatidylcholine, POPC, was examined at various concentrations of the lipid component. The lipid concentration was determined by a spectrophotometric method.

Inactivation Kinetics of Mushroom Tyrosinase by Cetylpyridinium Chloride

Journal of Protein Chemistry, 2003
Cetylpyridinium chloride (CPC) was found to inactivate tyrosinase from mushroom (Agaricus bisporus). CPC can bind to the enzyme molecule and induce the enzyme conformation changes. The fluorescence intensity (at 338.4 nm) of the enzyme decreased distinctly with increasing CPC concentrations, and a new little fluorescence emission peak appeared near 372

Evaluation of cetylpyridinium chloride for infection control in storage solution

Journal of Oral Rehabilitation, 2003
summary  Storage solution is used in in vitro experimental studies to prevent dehydration of teeth collected immediately after extraction and to prevent bacterial and fungal growth in the storage media. The chemical nature of the storing agent may affect the tooth structure and material properties at the tested interface.

Antimicrobial properties of an orthodontic adhesive combined with cetylpyridinium chloride

American Journal of Orthodontics and Dentofacial Orthopedics, 2006
Patients undergoing fixed appliance treatment are at greater risk for increases in salivary and plaque levels of Streptococcus mutans and an elevated risk of dental caries. Cetylpyridinium chloride (CPC) is known to be an effective antiplaque agent. The purpose of this study was to investigate whether incorporating CPC into a commercially available ...
