Stir bar sorptive-dispersive microextraction for trace determination of triphenyl and diphenyl phosphate in urine of nail polish users.

J Chromatogr A 2019 May 7;1593:9-16. Epub 2019 Feb 7.

Department of Analytical Chemistry, University of Valencia, 46100, Burjassot, Valencia, Spain. Electronic address:

This work describes a new analytical method useful for monitoring the human exposure to the endocrine-disrupting plasticizer triphenyl phosphate (TPP) via nail polish use. The method allows trace determination of this parent compound and its main metabolite, namely diphenyl phosphate (DPP), in urine samples of nail polish users. The method is based on a novel microextraction technique termed stir bar sorptive-dispersive microextraction (SBSDME) using a magnetic composite made of CoFeO magnetic nanoparticles embedded into a mixed-mode weak anion exchange polymer (Strata-X-AW), followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS).

Actas Dermosifiliogr 2018 Jul - Aug;109(6):508-514. Epub 2017 Nov 3.

Hospital General de Alicante, Alicante, España.

The first reported cases of allergic contact dermatitis from acrylates in manicure procedures in relation to the application of porcelain nails were published decades ago. The frequency of sensitization has increased due to the introduction of the so-called permanent nail polish containing photo-bonded acrylates, mainly involving the beauticians who apply them, and to a lesser extent, the consumers. The recent commercialized permanent polish kits for domestic use could trigger even higher degrees of sensitization. Read More

Simultaneous determination of alcohols including diols and triols by HPLC with ultraviolet detection based on the formation of a copper(II) complex.

J Sep Sci 2017 Nov 26;40(21):4168-4175. Epub 2017 Sep 26.

School of Science, Tokai University, Hiratsuka, Kanagawa, Japan.

We developed a reversed-phase high-performance liquid chromatography method with ultraviolet detection using on-line complexation with Cu(II) ion for analysis of five alcohols including diols and triol (methanol, ethanol, 1,2-propanediol, 1,3-propanediol, and glycerol). The Cu(II) ion concentration in the mobile phase had a great influence on the peak areas of these alcohols, but not on their retention times. Column temperature (25-40°C) and pH of the mobile phase did not affect the separation of analytes. Read More

Contact Sensitization to Allergens in Nail Cosmetics.

Dermatitis 2017 Jul/Aug;28(4):231-240

From the *Icahn School of Medicine at Mount Sinai; and †Department of Dermatology, Icahn School of Medicine at Mount Sinai, New York.

Ingredients found in the nail cosmetic industry, including but not limited to methacrylate and acrylate monomers, formaldehyde, and toluene sulfonamide-formaldehyde resin, can incite allergic contact dermatitis. An eczematous outbreak presents on areas surrounding the nail plate and may spread through contact transfer of the allergen, commonly to the face and neck. Even components that were originally deemed nonsensitizing, such as the ubiquitous cyanoacrylate adhesive family, have been found to be allergenic. Read More

Improving tribological and anti-bacterial properties of titanium external fixation pins through surface ceramic conversion.

J Mater Sci Mater Med 2017 Jan 24;28(1). Epub 2016 Nov 24.

School of Metallurgy and Materials, University of Birmingham, Birmingham, B15 2TT, UK.

In this study, an advanced ceramic conversion surface engineering technology has been applied for the first time to self-drilling Ti6Al4V external fixation pins to improve their performance in terms of biomechanical, bio-tribological and antibacterial properties. Systematic characterisation of the ceramic conversion treated Ti pins was carried out using Scanning electron microscope, X-ray diffraction, Glow-discharge optical emission spectroscopy, nano- and micro-indentation and scratching; the biomechanical and bio-tribological properties of the surface engineered Ti pins were evaluated by insertion into high density bone simulation material; and the antibacterial behaviour was assessed with Staphylococcus aureus NCTC 6571. The experimental results have demonstrated that the surfaces of Ti6Al4V external fixation pins were successfully converted into a TiO rutile layer (~2 μm in thickness) supported by an oxygen hardened case (~15 μm in thickness) with very good bonding due to the in-situ conversion nature.
