The lecture topics reported on actual trends and drivers in the European household laundry and care market, on performance testings of machine and hand dish detergents, on an update on disinfectants under the BPR options and of the revision of the Nordic Swan Ecolabel. Current issues in laundry hygiene at low washing temperatures and the occurrence of B-lactamases in washing machines as well as of microbial loads in food-associated appliances were discussed. By means of a model for a smelly washing machine, the appearance of malodor in washing machines can be simulated, so that by microbiota analysis a strain selection and identification of fungi and bacteria becomes possible.

Effects of a clean subcritical degreasing system on wool fibers / Qiao Xia in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CXVI, N° 5 (05/2021)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. CXVI, N° 5 (05/2021) . - p. 162-167 Titre : Effects of a clean subcritical degreasing system on wool fibers Type de document : texte imprimé Auteurs : Qiao Xia, Auteur ; Yinxuan Wang, Auteur ; Zongcai Zhang, Auteur ; Hong Dai, Auteur Année de publication : 2021 Article en page(s) : p. 162-167 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Caractérisation Dégraissage (nettoyage) Laine brute Pentane Le pentane est un alcane linéaire de formule C5H12. Le terme pentane désigne aussi par extension abusive17 les trois isomères C5H12 : le n-pentane, le 2-méthylbutane ou isopentane et le 2,2-diméthylpropane ou néopentane. Ces diverses molécules comportent toutes cinq atomes de carbone. Utilisations : Le pentane est un solvant couramment utilisé en chimie organique. Propriétés chimiques : Le pentane brûle dans l'air selon la réaction : C5H12 + 8O2 —> 5CO2 + 6H2O (Wikipedia) Stabilité thermique Thermogravimétrie Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : It makes sense to use environmentally friendly methods of degreasing in fur-making process. In this study, subcritical n-pentane was used to degrease wool fibers. Thermogravimetric analysis (TGA) was used to observe and analyze the properties of the subcritical n-pentane degreased wool fibers. The results showed that the thermal stability of the fibers increased. Fourier Transform Infrared (FTIR) spectroscopy was used to analyze the structural changes of macromolecular chains in wool fibers. It was found that when the pressure was higher than 0.4 MPa, the wool fibers underwent a conformational change with the α-helix changing to β-folding. If the pressure was as high as 0.6 MPa, the disulfide bonds in the wool fibers scale layer appeared to break. X-ray powder diffraction experiment was used to study changes in wool fiber aggregation morphology. It was demonstrated that the crystalline zone of wool fibers changed and the fibers index grew, from 22.89% to 30.19%. Field emission scanning electron microscopy and ultra-depth of field microscopy was used to analyze changes in the surface morphology of wool fibers. The results suggested that after the treatment, the wool fibers were not damaged and the impurities on the wool surface were reduced.

While keeping up with changing market dynamics they look to maintain or improve cleaning efficacy. Selecting the right ingredients is important to meet user needs for performance and efficiency and this article will discuss the most effective green chelants available for I&I cleaning – glutamic acid diacetic acid (GLDA) and methylglycine diacetic acid (MGDA). Both are readily biodegradable or biodegradable under anaerobic conditions and perform at high pH where other green chelants may underperform. GLDA is the preferred option for liquid formulations while MGDA is preferred for solid applications. Note de contenu : - How chelants work - The role of chelants in industrial cleaning : Textile cleaning - Cleaning and detergents - Comparisons of sequestering builders in detergents - GLDA and MGDA are the preferred green chelants - Stability constants indicate the strength of chelant/metal ion bonds - GLDA and MGDA vs citrate and phosphonates - Effect of GLDA and MGDA - GLDA and MGDA formulation guidelines - GLDA as performance booster for laundry detergents - Green chelates in strong degreasers for hard surface cleaning (HSC) - Green chelates in automatic dishwashing (ADW) formulations - Table : Chelants comparisons En ligne : https://drive.google.com/file/d/13il9rrUI8NsrL0Ne7XsuExHSjeBJCl8h/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=38942 [article]
