[article]  inGLOBAL PERSONAL CARE > Vol. 23, N° 2 (02/2022) . - p. 39-40 Titre : A biodegradable, broad-spectrum antibacterial Type de document : texte imprimé Auteurs : Anna Gripp, Auteur ; Christine Abbastante, Auteur Année de publication : 2022 Article en page(s) : p. 39-40 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Antibactériens Bactéries à gram négatif Bactéries à gram positif Chlorure de cétylpyridinium Conservateurs (chimie) Déodorants Formulation (Génie chimique) Peau -- Soins et hygiène Index. décimale : 668.5 Parfums et cosmétiques Résumé : When it comes to formulating personal care products, it is critical to select the most effective anti-bacterial agent. Especially when it comes to preservation, no single preservative is equally effective against all types of microorganisms. Cetylpyridinium chloride (CPC, Figure 1) is a quaternary ammonium compound that a literature search shows to be biodegradable and which offers effectiveness against many organisms. In the US, it may be used as a preservative and the FDA lists it as an antimicrobial agent. Outside the US, it may be used as an antibacterial agent. CPC has also been used widely in in over-the-counter products including mouthwash, throat lozenges, generally at 0.1-0.2%, nasal sprays and antiseptic (first aid) creams and lotions. Vertellus offers CPC in two forms : powder and liquid. The trade name for the liquid form is ‘Freshstatâ„¢ Cetylpyridinium Chloride’ and it is a 40% CPC in propylene glycol solution. This form provides formulation ease and production flexibility. Our CPC is made in the USA, comes in US and European Pharmacopeia forms, and also in technical grades. Based on common knowledge of commonly used preservatives, Table 1 compares a 40% CPC solution in propylene glycol to a variety of commonly used preservatives, i.e. methylparaben, ethyl paraben, propylparaben, butylparaben, phenoxyethanol, imidazolidinyl urea and chlorphenesin. This shows that CPC is effective over a broad pH range and exhibits broad anti-microbial efficacy against grampositive and gram-negative bacteria, broad spectrum activity, where the others have activity against fewer of these microorganisms.

Green chelating agents for industrial & institutional cleaning / Anna Gripp in SOFW JOURNAL, Vol. 149, N° 3 (03/2023)  

[article]  inSOFW JOURNAL > Vol. 149, N° 3 (03/2023) . - p. 38-43 Titre : Green chelating agents for industrial & institutional cleaning Type de document : texte imprimé Auteurs : Anna Gripp, Auteur ; Martin Heus, Auteur ; Sorel Muresan, Auteur Année de publication : 2023 Article en page(s) : p. 38-43 Langues : Anglais (eng) Catégories : Chélates Dégraissage (nettoyage) Détergents Nettoyage industriel Textiles et tissus -- Lavage Index. décimale : 668.5 Parfums et cosmétiques Résumé : Formulators in the industrial and institution (I&I) cleaning market are challenged to develop more efficient systems such as low temperature wash for energy conservation, lower cost and /or with a more sustainable footprint. 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]
