Dispergieren scherempfindlicher Polymere ohne Viskositätsverlust mittels Vakuum-Expansions-Methode
Dr. Hans-Joachim Jacob
(ystral gmbh, Ballrechten-Dottingen, Germany)
Polymere werden in Home- und Personal Care-Produkten überwiegend als Verdicker aber auch als funktionelle Additive eingesetzt. Sie erfordern einen kolloidalen Aufschluss und eine maximale Dispergierung, sind aber in der Regel bereits unmittelbar nach ihrer Hydratation äußerst scherempfindlich. Hauptproblem sind Polymeragglomerate, die beim Pulvereintrag entstehen und bei deren Abbau das bereits hydratisierte Gel bereits geschädigt wird.
Die Problemlösung bietet ein Verfahren, bei dem die Primärpartikel des Polymerpulvers noch vor dem Eintrag in die Flüssigkeit durch Vakuumexpansion vereinzelt, beim ersten Kontakt mit der Flüssigkeit vollständig benetzt, sofort dispergiert und agglomeratfrei hydratisiert werden. Anschließend braucht nicht mehr dispergiert zu werden. Es entstehen keine Agglomerate.
Mit diesem Verfahren lassen sich mit geringstem Polymereinsatz maximale Effekte erzielen. Viskosität, Thixotropie-Index, Transparenz, Filmbildungs- und Benetzungsverhalten und viele andere Eigenschaften erreichen ein bisher unerreichtes Niveau. Ein nachträgliches unkontrolliertes Verdicken ist ebenfalls ausgeschlossen.
Das Verfahren basiert auf einem Vakuum, welches direkt in der Flüssigkeit erzeugt wird. Der Polymereintrag erfolg unter maximalem Vakuum. Dir Polymerpartikel liegrn dabei komplett vereinzelt vor. Die Maschine kann an beliebigen Bahältern eingesetzt werden, es erfordert keinen Vakuumbehälter.
Das Verfahren arbeitet staub-und verlustfrei und kann problemlos in bestehende Anlagen integriert werden.
Im Vortrag wird auf die komplett unterschiedlichen Anforderungen beim Dispergiern von Carbomeren, Polyethylenoxiden, Zellloseethern, Xanthanen, Bentonen und anderen rheologischen Additiven im Detail eingegangen. Obwohl sich die Verarbeitungsmethoden für die genannten Pulvertypen grundlegend unterscheiden, können alle diese Produkte mit einer gemeinsamen Maschine verarbeitet werden.
Die Funktion wird im Detail vorgestellt und anhand sehr unterschiedlicher Polymere erläutert.

Apparative Methoden zum Vergleich der Reinigungsleistung an unterschiedlich ausgerüsteten oder behandelten textilen Materialien
Eva Gierling, Roswitha Hild, Florian Girmond
(Hohenstein Institute, Bönnigheim, Germany)
Immer wieder stehen Kunden oder Hersteller vor der Frage, welche Ausrüstung (z.B. soil-release) für unterschiedliche Verwendungszwecke auf dem eingesetzten textilen Material die geeignetste ist, und ob diese auch nach Gebrauchsbelastung noch funktionsfähig ist.
Im Vortrag werden unterschiedliche Test-Setups vorgestellt, in denen apparative die Unterschiede in der Abreinigung bzw. Aufnahme von verschiedensten Verfleckungen oder Flüssigkeiten, z.B. aus dem Lebensmittelbereich, erfasst werden. Der Vorteil der entwickelten, hauseigenen Methode besteht darin, dass hierbei nicht nur der Effekt im Neuzustand des Materials, sondern auch nach Gebrauchsbelastung (z.B. Scheuerpozesse oder Alterung) erfasst werden kann.

Zweckmäßige Testmikroorganismen zur Bewertung der Hygienewirksamkeit von Haushaltsgeschirrspülmaschinen
Caroline Amberg, Daniel Faeh
(Swissatest Testmaterials.ch, St. Gallen, Switzerland)
Food hygiene is a key measure to prevent food-borne infections. In the kitchen, hygiene hotspots can be found as chopping boards, kitchen work surfaces and cleaning clothes harbouring often more E. coli and Salmonella sp. than toilet seats. With the decreasing temperatures of dishwashing processes, the question comes up, if critical items like chopping boards still will be safely cleaned by a future dishwashing process.
In a recent study, the impact of temperature, detergent, soils and cycle duration on microbial reduction was investigated testing different potential test microorganisms in a lab test. The study aims to select relevant and differentiating test microorganisms for in situ tests in dishwashing machines.

Verbesserte Plastiktrocknung im gewerblichen Geschirrspülen
Dr. Arend J. Kingma
(BASF SE, Ludwigshafen, Germany)
Recent work in our labs has focused on the behaviour of low foaming surfactants as rinse aids in mechanical ware wash machines. More specifically we have evaluated single products as well as various mixtures in their wetting behavior on glass, steel, china and various plastics.
Initially we determined the contact angle of the surfactant solutions (60ppm) at 80°C, a temperature where normally the rinse step in a commercial ware wash machine is conducted.
These data were combined with the results of the circulation foam tests and used to chose the best performing surfactants and mixtures. These were then tested in a commercial ware wash machine on their drying performance, correlating these results with the respective contact angles.
In addition to the drying performance we measured the foam behaviour in the ware wash machine, using wheat flour, egg and milk powder as soil and a mixture of chelating agent and NaOH as detergent. This allowed us to find the optimum between plastic drying and defoaming.
In the presentation we show that the possibility exists to optimise formulations by using the wetting behavior and defoaming action data of the tested surfactants.

UV-Absorber für PET-Verpackungen – die attraktive Alternative zu UV-Filterzubereitungen
Anna Olshanskaya, et al.
(Milliken Europe, Gent, Belgium)
Today’s home and personal care formulations are highly complex. In addition to managing the stability and compatibility of products, formulators are faced with the challenges of meeting regulatory requirements and consumer needs. Requirements for good product quality at a reasonable price have been surpassed by market trends demanding producers to balance creativity, sustainability and effectiveness to grab consumer attention.
To differentiate their products on the shelves, the personal- and home-care industries are embracing memorable colors, active ingredients and special additives to catch the eye. However, some of these ingredients, particularly natural ones, are sensitive to UV influence and require special UV protection in order to keep a formulation effective and safe for its whole shelf life. One option is to add UV filters directly into the formulation. But the use of mainly organic, benzophenone-4 type UV filters to stabilize UV-sensitive ingredients adds complexity for the formulator. Furthermore, lack of compliance with most organic/natural based regulations excludes their use in natural-based products.
Milliken offers an alternative way to provide UV protection to formulations without reworking the composition. The company has developed a special additive for PET packaging which is used as a UV absorber and has a wider range of UV protection than other products (up to 390 nm). It has proven efficacy in protecting sensitive ingredients such as vitamins and dyes. The additive is crystal clear, which retains the high transparency of PET without any unwanted shading. Use of the Milliken UV absorber additive in the packaging instead of a filter in the formulation avoids the complexity, and potential for incompatibility, of an additional formulating step. Importantly, it gives more freedom in formulation design and confidence in the end-product quality, as it is possible to extend the formulation shelf-life and avoid color fading while keeping the visual appeal of a product in transparent packaging.

Die Formulierung von Flüssigwaschmitteln mit Enzymen und starken Chelatbildnern
Henrik Lund
(Novozymes A/S, Denmark)
Household care liquid laundry detergents benefit by the inclusion of strong chelators (metal-complexing compounds), both for specific stain removal, but also to prevent a negative influence of metal ions found in the wash water. Such a reduction in overall detergency can be reduced surfactant performance, incrustations, chalky or iron deposits in the machine and/or fabric. Another well-known and inevitable performance factor of modern liquid detergents are the multienzyme solutions. However, some enzyme classes, e.g. proteases and amylases are dependent on certain metal ions for optimal stability and may therefore be sensitive to the presence of strong chelators. This, chelator – enzyme conundrum, becomes a limiting factor, reducing the formulation flexibility for soapers who strive to use the best from both worlds of chelators and enzymes, in the production of high performance, sustainable detergents.

Dr. Rebecca Blell
(Borregaard AS, Sarpsborg, Norway)
Exilva, the world’s first commercial scale Microfibrillated Cellulose (MFC) produced by Borregaard, belongs to a new class of sustainable rheological additives with multifunctional properties.
The factory is located at Borregaard’s production facility in Sarpsborg, Norway, and uses Norwegian spruce as the raw material. The proprietary process technology has been developed by Borregaard over the last 10 years and is vital to achieving Exilva’s high performance.
The world’s first commercial-scale production facility for Exilva microfibrillated cellulose (MFC) has a capacity of 10.000 metric tonnes of 10% Exilva paste. The plant will be in operation from Q3 of 2016.
Borregaard currently also operates a demonstration plant with a capacity of 1000 tons 10% paste.
Exilva is designed to enhance stability and rheological performance thanks to its three-dimensional network of microfibrils in water and in polar organic systems. The features of Exilva, beyond rheology, are shown in various formulations.
In personal care applications results show that Exilva functions not only as a rheology modifier, but also show excellent soft focus performance, improved skin feel, improved stability of the finished product, and all of these properties together combined. In addition, the stability of Exilva in a wide pH range (1 to 13) allows its use in a wide range of applications including house hold products, providing flexibility when producing formulations.
Borregaard, producer of Exilva, has one of the world's most advanced and sustainable biorefineries. By using natural, sustainable raw materials, Borregaard produces advanced and environmentally friendly biochemicals that can replace oil-based products.

Mikrobielle Tenside: Vom Labor auf den Markt
Dr. Sophie Roelants¹ ², Wim Soetaert¹ ², et al.
(¹ Bio Base Europe Pilot Plant, Ghent, Belgium; ² InBio.be (Ugent), Ghent, Belgium)
Biosurfactants have been the subject of an impressive amount of research efforts, both by academia as by the industry. Two major factors that have been limiting real commercialization of biosurfactants in the past are firstly the limited structural variety and secondly the high production price due to low inherent productivities, small scale and/or a lack of process knowledge.
A solution can be offered by an integrated process design (IPD) approach, where the entire innovation chain is taken into account. Genetic engineering on one side of the spectrum generates new strains, which are subsequently subjected to thorough investigation of the production processes, with feedback coupling to the strain level. Subsequent scale up on one hand enables assessing the scalability of the processes and performing techno-economical and LCA analyses, but on the other hand also results in the generation of kg scale biosurfactant samples of high purity. The availability of such large amounts of a portfolio of molecules enables thorough application research of the new molecules and their derivatives in a vast variety of sectors.
This approach has been applied for one of the showcases of biosurfactant production: the yeast Starmerella bombicola. The development of a molecular toolbox enabled the generation of several new S. bombicola strains, efficiently producing new-to-nature biosurfactants. These new strains were subjected to an iterative optimization process, while the production processes (fermentation and purification) for each new biomolecule/strain were investigated in parallel. Dedicated application research identified possible valorization options and a business case for the commercialization was recently finalized. Finally, successfull scale up to the 15 m³ scale proved technical feasibility and generated the first big batch of (new-to-nature) biosurfactants. The combination of these efforts is expected to result in real market penetration of these molecules in the near future.
