Acute inhalation toxicity of cetylpyridinium chloride
Food and Chemical Toxicology, 1991Cetylpyridinium 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.

Study of cetyltrimethylammonium and cetylpyridinium adsorption on montmorillonite
Journal of Colloid and Interface Science, 2006Adsorption of cetyltrimethylammonium (CTA) and cetylpyridinium (CP) onto Na-rich montmorillonite (MMT) was studied. For this purpose, the adsorption isotherms of CTA and CP, along with desorption curves of metal cations (Na+, K+, Ca2+, Mg2+), were obtained by means of capillary isotachophoresis and atomic absorption spectrometry.

Journal of Molecular Structure, 2019
Abstract The cetylpyridinium (CP) dipicrylamide (DPA) ion pair has been synthesized and characterized by the FT-IR and NMR (1H and 13C) spectroscopy, theoretically studied and tested as ion-exchanger for cetylpyridinium selective electrodes. The molecular dynamics and further DFT optimization indicate face-to-face π-π stacking interaction between ...

Influence of Cetylpyridinium Chloride on Corneal Permeability to Penicillin
Journal of Pharmaceutical Sciences, 1979The 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.

The Ordering of Cetylpyridinium Bromide on Vermiculite
Clays and Clay Minerals, 1978AbstractX-ray superlattice reflections, infrared spectroscopy, and chemical analyses have established that cetylpyridinium bromide (CPB) is highly ordered when adsorbed on vermiculite. The molecules, which stand at about 57° to the silicate surface, form close-packed arrays.

The interaction of amylopectin with cetylpyridinium chloride
Journal of Colloid Science, 1961Abstract 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.

Efficacy of Cetylpyridinium Chloride Used as Oropharyngeal Antiseptic
Arzneimittelforschung, 2011Cetylpyridinium 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, 1990Conventional 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, 2001The 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 ...
