Vaisselle -- NettoyageIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Measures to avoid unpleasant odours in dishwashers and washing machines entail improving the hygiene status by, among other things, achieving wash temperatures of >50° or 60°C. The development of a phosphate-free dishwasher detergent required a complete reformulation to ensure 100% product performance in washing and rinsing in systematic individual tests of the ingredients. Excellent drying of plastics is the biggest challenge in dishwashing. Excellent drying performance depends on the spreadability of the water droplets through the formation of a larger, evenly distributed water surface and the resulting removal from the plastic surface by water sheeting. Combining excellent defoaming surfactants with excellent wetting surfactants significantly improves drying performance on plastics.

Lactique, AcideL'acide lactique est un acide organique qui joue un rôle dans divers processus biochimiques. Un lactate est un sel de cet acide. Contrairement à ce que peut laisser penser son nom, l'acide lactique n'est pas présent uniquement dans le lait, mais également dans le vin, certains fruits et légumes, et dans les muscles.
L'acide lactique est un acide alpha hydroxylé, sa formule chimique est C3H6O3 et sa structure se reflète dans son nom systématique, l'acide 2-hydroxypropanoïque.

Vaisselle -- NettoyageIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Natural origin, safety and sustainability range among the top trends in home care. This includes the preservatives used in such formulations. Consumers are becoming increasingly aware of the potential allergenic and sensitising properties of common active substances. Regulatory bodies are reacting to new scientific evidence and restricting the application of these ingredients. Here, we present L(+)-lactic acid as a viable alternative to synthetic and hazardous preservatives. We demonstrate its efficacy in simple aqueous surfactant solutions and typical home care formulations including softener, surface cleaner and hand dish wash detergent.

Titre : Green raw material & product preservation : Sustainable, readily biodegradable preservation is key for consumer products, as well as their components Type de document : texte imprimé Auteurs : Amber Yarnell, Auteur ; Stephen Foster, Auteur ; Jonathan Rabiei, Auteur ; Jenna Blankenship, Auteur Année de publication : 2021 Article en page(s) : p. 2-7 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Benzoate de sodium Le benzoate de sodium, de formule chimique (Na+ + C6H5COO-)(NaC6H5COO) est le sel de sodium de l'acide benzoïque, connu sous le nom E211 comme additif alimentaire. Soluble à raison de 640 parts pour 1000 d'eau à 25 °C. Il précipite en présence d'un acide concentré (ex.: l'acide sulfurique concentré) en donnant de l'acide benzoïque (très peu soluble dans l'eau) dont on peut analyser plus facilement le point de fusion. Sa dissolution aqueuse engendre une augmentation du pH.
L'acide benzoïque est produit industriellement selon 3 voies :
1. Oxydation de naphtalène en anhydride phtalique en présence de catalyseur oxyde de vanadium. L'anhydride phtalique est ensuite décarboxylé produisant l'acide benzoïque.
2. Oxydation d'un mélange de toluène et d'acide nitrique produisant l'acide benzoïque.
3. Hydrolyse du trichlorobenzène produisant l'acide benzoïque.
L'acide benzoïque est ensuite dissout dans une solution d'hydroxyde de sodium pour former du benzoate de sodium.
Le benzoate de sodium est utilisé comme conservateur alimentaire, autorisé sous condition et référencé en Europe sous le code E211.

Vaisselle -- NettoyageIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : What does the word “sustainable” mean to the everyday consumer? While it’s clear that sustainability is growing in importance for home care and consumer products, the term can encompass a number of different considerations; biodegradability, ingredient origin, ethical sourcing, safety, potential hazards, and eco-friendly packaging are all critical aspects that can impact whether a product is perceived as a green choice (Figure 1).
Green labels are increasing in popularity, as they make it easier for consumers to decipher which products align with their personal values and find them on store shelves. While the criteria for each green label certification is different, they each look at certain factors to determine which products meet standards for sustainability. Ingredient selection is an important part of the process of applying for a green label certification, and many programs use approved or restricted ingredient lists to provide guidance to manufacturers seeking certification.Note de contenu : - The importance of ready biodegradability

Vaisselle -- NettoyageIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Trisodium citrate is an ecologically friendly, non-toxic alternative to phosphorus-based builders in automatic dishwashing detergent (ADWD) tablets. It exists in two forms: trisodium citrate dihydrate (TSC), which contains two water molecules in the crystal, and trisodium citrate anhydrous (TSA). The latter is produced by removing the water of crystallisation from the crystalline matrix, thus creating a porous structure. TSA can be loaded with liquid substances and will remain a free-flowing powder because of these pores. In the present analysis, the effects of TSC, TSA and mixtures thereof on critical tablet parameters, such as disintegration and stability, were examined. The study shows that replacing part of the TSC in the formulation with TSA decreases disintegration time and increases breaking strength after tablet pressing. This finding is supported by an existing patent (EP 3 431 575), which additionally shows that mixtures of TSA and TSC improve tablet cleaning performance. Furthermore, the present study demonstrates that the storage stability in polypropylene packaging of tablets containing TSA/TSC mixtures is comparable to that of tablets which only use TSC as the builder. Thus, TSA and TSC are not only eco-friendly builders, but can be used to modulate tablet disintegration time and stability as needed. Note de contenu : - Experimental procedure
- Results : Mixing TSA and TSC accelerates tablet disintegration
- TSA increases breaking strenght
- Equally good storage stability in polypropylene

Vaisselle -- NettoyageIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Rinse surfactants are core ingredients of automatic dishwashing (ADW) product formulations, integral to key performance aspects. As Home Care product launches with environmental and ethical claims now exceed those without, formulators require the support of ingredient developers to quickly identify new more sustainable surfactant options suitable for delivering on these criteria plus consumer-demanded high effectiveness in rinse performance.
To effectively achieve this balance, the surfactant creator is challenged to replace some or all ingredient building blocks with more renewable, sustainable alternatives.
Supporting more efficient and systematic surfactant development for sustainable ADW formulations, Clariant has introduced a new system for efficiently pre-screening surfactant characteristics and relating them to required ADW performance benefits. The process advantages extend beyond Clariant’s faster and resource-saving development of market-relevant ingredients. The pre-screening also provides performance indicators plus temperature and concentration dependent measurements to support customers’ selection of surfactants based on specific needs and formulations.
This paper details the unique combination of laboratory methods employed to ultimately select the best-performing surfactant within a product group. The pre-screening study example features renewable substances with RCI >50% compared to benchmark petrochemical-based products.Note de contenu : - Introduction : Efficiently finding ingredients for changing needs
