A Novel Electrochemical Sensor Based on Printex L6 Carbon Black Carrying CuO/Cu2O Nanoparticles for Propylparaben Determination
(2018-12-01)
The paper reports the development of a new sensor based on Printex L6 (CPL6) carbon black modified with copper oxides (CuO/Cu2O) nanoparticles and its application towards the determination of Propylparaben (PP). In fact, ...
Parabens inhibit hNaV 1.2 channels
(Elsevier Masson, 2020-08)
Propylparaben, a commonly used antimicrobial preservative, has been reported as an anticonvulsant agent targeting neuronal Na+ channels (NaV). However, the specific features of the NaV channel inhibition by this agent have ...
Anticonvulsant effect of sodium cyclamate and propylparaben on pentylenetetrazol-induced seizures in zebrafish
(Wiley-liss, Div John Wiley & Sons Inc, 2017-04)
Screening for novel anticonvulsant drugs requires appropriate animal seizure models. Zebrafish provide small, accessible, and cost-efficient preclinical models applicable to high-throughput small molecule screening. Based ...
Parabens Removal from Domestic Sewage by Free-Floating Aquatic Macrophytes
(Springer, 2019-08-01)
Parabens are substances that prevent or delay the deterioration of cosmetics, drugs and food caused by the action of microorganisms. Recent studies report their potential to affect human health. The present study reported ...
A simple and highly selective molecular imprinting polymer-based methodology for propylparaben monitoring in personal care products and industrial waste waters
(Elsevier Science, 2018-02-04)
In this work, a novel molecularly imprinted polymer (MIP) proposed as solid phase extraction sorbent was developed for the determination of propylparaben (PP) in diverse cosmetic samples. The use of parabens (PAs) is ...
Análise de parabenos em águas superficiais urbanas por extração em fase sólida on-line usando cromatografia líquida acoplada à espectrometria de massas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação de Mestrado Profissional em Química - PPGQCâmpus São Carlos, 2017-05-24)
Parabens are the most popular antimicrobials used for more than 100 years in personal care products, the most known are methylpaben, ethylparaben, propylparaben and butylparaben. The continued release of these antimicrobials ...
Electrodeposition of WO3 on Ti substrate and the influence of interfacial oxide layer generated in situ: A photoelectrocatalytic degradation of propyl paraben
(Elsevier B.V., 2019-01-15)
Ti/TiO2-WO3 photoanode composites were successfully synthesized through a simple electrochemical deposition of WO3 films on Ti substrate. The electrochemical deposition was evaluated in the following periods: 2.5; 5; 10; ...
Propylparaben applied after pilocarpine-induced status epilepticus modifies hippocampal excitability and glutamate release in rats
(Elsevier Science, 2017-03)
Propylparaben (PPB) induces cardioprotection after ischemia–reperfusion injury by inhibiting voltage-dependent Na+ channels. The present study focuses on investigating whether the i.p. application of 178 mg/kg PPB after ...
Drug-excipient compatibility studies in binary mixtures of Avobenzone
(Society of Cosmetic Chemists, 2013-10)
During preformulation studies of cosmetic/pharmaceutical products, thermal analysis techniques are very useful to detect physical or chemical incompatibilities between the active and the excipients of interest that might ...
