Aim: Demodex parasites have been linked to dermatological disorders, especially rosacea, without a proven mechanism. Moreover, some anti-Demodex agents demonstrate dual therapeutic effect related direct on the skin disorder along with decreased number of mites. Despite being considered first-line treatment approach for azelaic acid's efficacy against mites has not investigated. In current study...

A UPLC-MS/MS method was developed for simultaneous determination of 7 whitening ingredients: nicotinamide, kojic acid, Tranexamic raspberry glycoside, azelaic magnesium ascorbate phosphate and β-Arbutin in cosmetics. The active components were extracted from cosmetics by supersonic extraction with sodium chloride dichloromethane to disperse the sample, 0.015 mol/L potassium dihydrogen solution ...

Abstract For peanuts, roasted at 170 °C, the formation of selected glycerol-bound oxidized fatty acids (GOFAs), namely 9-oxononanoic acid (9-ONA), azelaic (AZA) and octanoic acid, was observed by GC-MS (EI). The content as well AZA increased with continuous roasting time (from 59 mg/kg peanut oil to 101 from not detectable 8 oil, respectively), whereas 9-ONA initially decreased 25 (20 min) agai...

A series of novel bio-polyester nanocomposites based on glycerin and azelaic acid as monomers incorporating hydroxyapatite (HA) nanoparticles were fabricated via in situ polymerization method. Chemical structure the samples was investigated by 1H-NMR, 13C-NMR, Fourier-transform infrared spectroscopy (FTIR). Energy dispersive X-ray-mapping analysis illustrated that well dispersed poly (glycerol ...

The crystalline structure of two biodegradable odd-odd polyesters (i.e., poly(nonamethylene pimelate) (PES 9,7) and poly(nonamethylene azelate) (PES 9,9)) was investigated by means of electron and X-ray diffraction of single crystals and oriented fibers, respectively. Truncated rhombic crystals were obtained with an aspect ratio that was strongly depended on the supercooling degree. The crystal...

Microalgae oil serves as a feedstock for a biorefinery approach to mid-chain (di-)carboxylic acid esters, currently only accessible via demanding synthetic routes. Via the butenolysis of monoand poly-unsaturated fatty acids, short-chain unsaturated fatty acid methyl esters and monoand di-enes were produced in a high selectivity. These olefins were further processed into value added linear mid-c...
