A distinction should be made between the malodour on the textiles after washing and the malodour generated by microbial growth of remaining microorganisms during the drying process. The malodour-causing light volatile substances are, chemically speaking, fatty acids, nitrogen and sulphur compounds. Note de contenu : - Axillary odour
- Malodour formation on textiles
- Odour sources in the washing process

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. Note de contenu : - TABLES : Biomonitors of risk group 1 and 2 were tested in the same cleaning cycles in the diswasher
- FIGURES : Functions and ingredients of diswasher tabs - Phosphate-free builders reduce the carbon footprint by approximately 67 % - Amylase and protease work very effectively together in removing complex food residues (washing conditions : 30 minutes soaking - rinsing only - no scrubbing) - Excellent drying performance ofoptimised rinse aid formulations in warewashing machines

EnzymesUne enzyme est une protéine dotée de propriétés catalytiques. Pratiquement toutes les biomolécules capables de catalyser des réactions chimiques dans les cellules sont des enzymes ; certaines biomolécules catalytiques sont cependant constituées d'ARN et sont donc distinctes des enzymes : ce sont les ribozymes.
Une enzyme agit en abaissant l'énergie d'activation d'une réaction chimique, ce qui accroît la vitesse de réaction. L'enzyme n'est pas modifiée au cours de la réaction. Les molécules initiales sont les substrats de l'enzyme, et les molécules formées à partir de ces substrats sont les produits de la réaction. Presque tous les processus métaboliques de la cellule ont besoin d'enzymes pour se dérouler à une vitesse suffisante pour maintenir la vie. Les enzymes catalysent plus de 5 000 réactions chimiques différentes2. L'ensemble des enzymes d'une cellule détermine les voies métaboliques qui peuvent avoir lieu dans cette cellule. L'étude des enzymes est appelée enzymologie.
Les enzymes permettent à des réactions de se produire des millions de fois plus vite qu'en leur absence. Un exemple extrême est l'orotidine-5'-phosphate décarboxylase, qui catalyse en quelques millisecondes une réaction qui prendrait, en son absence, plusieurs millions d'années3,4. Comme tous les catalyseurs, les enzymes ne sont pas modifiées au cours des réactions qu'elles catalysent, et ne modifient pas l'équilibre chimique entre substrats et produits. Les enzymes diffèrent en revanche de la plupart des autres types de catalyseurs par leur très grande spécificité. Cette spécificité découle de leur structure tridimensionnelle. De plus, l'activité d'une enzyme est modulée par diverses autres molécules : un inhibiteur enzymatique est une molécule qui ralentit l'activité d'une enzyme, tandis qu'un activateur de cette enzyme l'accélère ; de nombreux médicaments et poisons sont des inhibiteurs enzymatiques. Par ailleurs, l'activité d'une enzyme décroît rapidement en dehors de sa température et de son pH optimums.

SurfactantsIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : The 64th SEPAWA Congress was held in conjunction with the 131h European Detergents Conference (EDC) at the Estrel Congress Center in Berlin.
The change of venue to Berlin was well received, as evidenced by an increase in the number of delegates, to more than 3,000 from 49 countries, as well as growth in the number of exhibitors, to 254 companies. These figures represented new records for both participants and exhibitors.
A programme of 39 scientific lectures offered a broad range of comprehensive information on the characteristics and functions of surfactants and detergents, examining both the scientific basis of these products in the 13th European Detergents Conference, as well as their practical applications in the different sessions on detergents, cleaning products and cosmetics. The lecture series "forum for Innovations" featured 69 short presentations on new product developments, applications and procedures for detergents and cosmetics.
The Detergents Committee of the German Chemists Society (GDCh/HAD) and the SEPAWA Specialist Group Legislation, Environnent and Consumers (LUV) addressed the subject of the sustainability of detergent ingredients with joint reports on the biodegradability of fragrances in detergents, the traceability of certified oil palet products and the marketplace for RSPO credits, and current legislative regulations.
The cosmetics lectures covering care and protection of skin and hair by individual substances and new applications were presented in conjunction with the SEPAWA Specialist Group Cosmetic Applications and Technology (CAT) and the German Society for Scientific and Applied Cosmetics (DGK).
The German Society of Perfumers (DGP) presented an interactive show about fragrances entitled "Bridge of Senses", shared treasures from the Osmothèque in Versailles and revealed new paths in the perfumery sector.
The SEPAWA Young Researcher Award was presented for 3 outstanding master's, 2 bachelor's and 3 doctoral theses. The SEPAWA Innovation Award for new developments in the field of cosmetics and detergents was granted to 3 prizewinners.
In addition, the GDCh Specialist Group Detergency and Formulations awarded the Young Researcher Award for outstanding scientific research at the 13th European Detergents Conference.Note de contenu : - Structures and properties of surfactant, nano, micro and gel systems

Produits nettoyantsIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : A method of treating textiles with an antimicrobial agent over a plurality of wash cycles, each consisting of a wash cycle and a subsequent treatment cycle, by dispensing the textile with a solution of a predetermined concentration of an antimicrobial agent containing a metal ion such as silver ions. The concentration is not sufficiently high enough in the first wash cycle to achieve a predetermined antimicrobial efficacy for the textile, but sufficient to achieve the predetermined antimicrobial efficacy for the textile due to the combination of the first wash cycle and one or more subsequent wash cycles. This process can reduce the antimicrobial load of the entire laundry inventory by 50 to 90%. Note de contenu : - Laundry hygiene in the institutional sector
- Antimicrobial effectiveness of textiles through infused silver ions
- Taking water quality into account
- Germ transmission through bed sheets and patient
