Sirichai S, Hasajitto C.
PMID: 15636528
Anal Sci. 2004 Dec;20(12):1741-4. doi: 10.2116/analsci.20.1741.

This paper describes the methodological optimization and validation of a simple micellar electrokinetic chromatography for the rapid simultaneous separation of 2-methyl-4-isothiazolin-3-one, methylparaben, ethylparaben, propylparaben, and butylparaben. By using a 30 mM phosphate buffer (pH 7.2) containing 30 mM sodium...

J Food Prot. 1980 Mar;43(3):191-194. doi: 10.4315/0362-028X-43.3.191.

Inhibition of Salmonella typhimurium and Staphylococcus aureus in Trypticase Soy Broth by the propyl ester of p-hydroxybenzoic acid (propyl paraben, 0 to 500 ppm) and butylated hydroxyanisole (BHA, 0 to 400 ppm) alone and in combination was studied. A...

Solid-State Characterization and Compatibility Studies of Penciclovir, Lysine Hydrochloride, and Pharmaceutical Excipients.

Materials (Basel, Switzerland)

Meira RZC, Biscaia IFB, Nogueira C, Murakami FS, Bernardi LS, Oliveira PR.
PMID: 31569620
Materials (Basel). 2019 Sep 27;12(19). doi: 10.3390/ma12193154.

The physical and chemical characterization of the solid-state properties of drugs and excipients is fundamental for planning new formulations and developing new strategies for the treatment of diseases. Techniques such as differential scanning calorimetry, thermogravimetry, X-ray powder diffraction, Fourier...

Simultaneous Determination of Isothiazolinones and Parabens in Cosmetic Products Using Solid-Phase Extraction and Ultra-High Performance Liquid Chromatography/Diode Array Detector.
