60 Years Sinner Circle: The Future of Washing and Cleaning
Prof. Dr. Thomas Müller-Kirschbaum, Henkel AG & Co. KGaA
Spoken Language: German Category: Home Care / Other (SC HC Special) Sixty years ago, Dr. Herbert Sinner, head of detergents development at Henkel, has defined chemistry, mechanical power, temperature and time as the four universal factors which determine the success of a wash cycle. If each of these factors represent a circular sector with a size representing the relative contribution of the particular factor, all four circular sectors have to add up to a full circle, named for its inventor Sinner Circle. The validity has not changed. But the demands for the several factors have significantly changed. The same is true for their content und understanding. For this reason, it will be fascinating to extend the development of the Sinner Circle and to anticipate the future of washing. Four megatrends will have significant impact: New business models, new product forms and product designs, new ingredients and cleaning technologies and the requirements of a climate-neutral circular economy. Intensity and dynamic of change are driven by growing digitalization. Like industrial processes are reproduced in “digital twins”, the digitalization of the Sinner Circle will create a digital twin of the wash cycle. This will enable fully new opportunities for prediction and optimization. The factor chemistry will need to change the most. Liquid and convenient product forms will increase. Biochemistry will catch up with chemistry. Disruptive innovations will derive from a better molecular understanding of stains and soiling. Ecotoxicological properties of all ingredients will improve further. The trend for compaction will be driven by digital business models like ecommerce. In order to meet the needs of a climate-neutral circular economy, the footprint of ingredients must be reduced. The development of the Sinner Circle results in a visionary outlook into the future of washing and cleaning – and show which next steps are required today.

Automatic Dishwashing Gels – a Trending Product Format with Special Formulation Needs
Frank-Peter Lang, BASF SE
Spoken Language: English Category: Home Care / Cleaning Agents Gel formulations are the fastest growing category in modern Automatic Dishwashing (ADW). Already known in the market for some years, their share of new product launches peaked at 31% - tendency growing. Driven by the consumers demand for convenience and product aesthetics, this innovative product format comes with significant challenges regarding formulation technology and formulation stability. Water-based gel formulations often suffer from various ingredient incompatibilities and therefore disappoint in terms of performance. The aesthetically unpleasing appearance of increased spotting and filming leads to less shine of dishes and cutlery, which is a stronghold of modern ADW tablets. Recent application test results and a high-performance formulation approach will be shown.

Towards More Naturally Sourced, High Performance Cleaners – Vegetable-Based Narrow Range Ethoxylates
Dr. Sorel Muresan, Nouryon
Spoken Language: English Category: Home Care / Cleaning Agents Consumers are increasingly aware of their responsibility to the environment in the selection of their cleaning products, with an increasing focus on renewable and sustainably sourced surfactants. Of course, this wish is accompanied by an expectation of excellent product performance along with low ecotoxicity and minimal environmental persistence. In household hard surface cleaning, ethoxylates of fatty alcohols have traditionally been used in such formulations, with the hydrophobe moiety usually originating from a synthetic, crude-oil derived source. Newly introduced vegetable-based narrow range ethoxylate products offer superior cleaning, environmental performance, low odor and desirable physical characteristics that can meet and exceed formulator requirements, and delight consumers. Incorporation of these surfactants into hard surface cleaning formulations will mean that today’s consumer need no longer compromise their product performance whilst still achieving their sustainability aspirations.

Exploring New Applications on Personal Care: Balancing our Skin Microbiota
Andrea Maltagliati, ROELMI HPC
Spoken Language: English Category: Personal Care / Skin Microbiome A biotechnological GMO-free metabolite from selected bacterial strain (INCI: Ectoin) allows fastest recovery of skin from stress, in order to maintain better conditions for a good growth and equilibrium of skin microbiota. Independent from peculiar human microbiome composition, it is effective on whatever skin type, as its first target is the homeostasis of skin microenvironment and the response to unbalanced conditions. Ingredient efficacy has been tested and validated by in-vitro and in-vivo tests performed by external and independent lab. The maintenance of cells homeostasis after osmostress has been performed in-vitro by addition to the cell culture medium salt (simulating marine environment), chlorine (simulating swimming pool environment) and artificial and raised temperature conditions (simulating sweat). Results confirmed the ability to equilibrate the environment around cells after external stresses, allowing a better survival and activity of cells. Cell viability and metabolism are improved (respectively +26.6% and +71.6%). Ectoin enhanced the surface expression of ß-Defensin in cells treated with LPS ina in-vitro evaluation of the synthesis promotion of antimicrobial peptides that contribute to the skin’s antimicrobial defense on cell cultures, resulting in a protective effect by balancing cells external environment. A clinical-instrumental study has been carried out on 20 healthy Chinese subjects, aged between 18-80 years old, living in Beijing. Product effects were evaluated after 14 and 28 days of daily product use to quantify the composition of skin flora (paying attention to pathogens species reduction and resident species balancing). In-vivo genomic tests confirm the skin protection activity with particular attention towards Skin Microbiome’s balance (Phylum and Genus), showing a more balanced skin microbiome compared to placebo. In-vivo dermatological tests confirm the promotion of healthier skin (+5.5% moisturization, +4.8% elasticity) and skin profilometry by decreasing skin roughness (-13.3%) and wrinkle appearance (-7.8%) as well as better skin smoothness, thanks to microbiota’s homeostasis.

OXISMOOTH® Line: Multifunctional Green Emollients that Deliver Unique Benefits with Superior Sensory Experiences
Alexandra Sartori, Oxiteno S/A
Spoken Language: English Category: Personal Care / Hair and Skin Care One of the major trends in the Cosmetics and Personal Care market is the increase of consumers’ awareness regarding health and well-being and their preference for more natural formulations, to the detriment of those based mostly on petrochemical derivatives. Such trend demands an increasing supply of environmentally friendly and sustainably produced cosmetic ingredients from the industry. In terms of synthetic ingredients, one of the main targets for replacement has been silicones. The claim "silicone-free" is one of the most seen in the market today, so alternatives for this substitution are gaining huge importance. Emollients are ingredients that provide a smooth and pleasant feeling to the skin and hair, and are often used in moisturizing creams and lotions, anti-aging face creams and sunscreens, and also in shampoos, hair conditioners, among other skin and hair care products. Mainly due to cost constraints, most of the emollient esters used today still consist of molecules produced from petrochemical derivatives. In this scenario, Oxiteno developed a new line of emollients from 100% renewable resources, consisting of the following ingredients: isoamyl caprylate/caprate, isoamyl cocoate and isoamyl palmitate/stearate. All three esters are manufactured with isoamyl alcohol, which is obtained in a sustainable approach by purifying the fusel oil, a residue from the production of ethanol from sugarcane, and fatty acids derived from vegetable oils that enabled the line to be approved COSMOS by Ecocert. All esters of the new platform are biodegradable, free of preservatives, non-occlusive, non-cytotoxic / phototoxic and dermatologically tested. Isoamyl Caprylate/Caprate is also an effective solvent of UV filters for sunscreens, consisting of a "green" alternative to other common synthetic solvents. OXISMOOTH line efficacy and application results indicate that a range of sensory attributes as well as high spreadability, low tack, rapid absorption and improved combability can be achieved.

Extremosio™: A Novel Cosmetic Active with Autophagic Effect to Prevent and Reduce Skin Aging
Dr. Elodie Metral, NAGASE Personal Care
Spoken Language: English Category: Personal Care / Skin Care Aging is an ineluctable phenomenon resulting from the progressive failure of maintenance and repair cell functions. Skin is the organ which aging signs are the most visible. Indeed, this loss of cell functions leads to wrinkles, dryness and age spots. Autophagy is a natural cellular detoxification process which maintains cell health by recycling long-lived proteins and damaged organelles. It homeostatically occurs around skin basal layer and is activated in specific conditions, for example, when toxic cytoplasmic materials need to be removed. By aging, autophagy process is decreased, and this leads to the accumulation of defective molecules which consequently interferes with normal cellular mechanism that result in the loss of cell functions. Trehalose, a naturally occurring disaccharide, was recently characterized as a safe autophagy inducer. Since trehalose itself is hydrophilic, Extremosio™, consists of plurilamellar liposomes loaded with trehalose, is designed to improve penetration and provide an innovative solution to this significant impairment of the autophagic flux. Both in vitro and in vivo studies demonstrated the capability of Extremosio™ with activation of autophagy and reduction of age-related skin damages. In vitro study showed that Extremosio™ protects keratinocytes from UVB-induced damage and senescence, as well as prevents and reduces skin pigmentation. Moreover, human study proved the improvement of skin quality after application of 5% Extremosio™ for 45 days in comparison to placebo. The subjects were able to find the improvement of the skin in hydration, homogeneity and reduction of wrinkles with Extremosio™. To conclude, Extremosio™ is a novel anti-aging solution that reactivates the natural cellular detoxifying system, thus helping the skin cells to fight against ageing via autophagy activation. Furthermore, considering the numerous emerging processes involving autophagy (i.e. cell response to pollution, sebum composition), Extremosio™ may be capable to help protecting or improving the skin for a general and complete cosmetic strategy.

Effective Cleaning through a Second Skin – New Insights Verify Why Proteins Improve Cleaning
Dr. Matthias Reihmann, GELITA AG
Spoken Language: English Category: Home Care / Cleaning Agents The innovative easy-to-clean concept with functional collagen peptides that form hydrophilic protective films has been used successfully in professional vehicle cleaning over the last few years. In addition to excellent cleaning results, significantly extended cleaning cycles and reduced water consumption are well documented benefits. Meanwhile the protein protection films are also used in household cleaners. Here, the current focus is on effective ready-to-use products with simplified and reduced cleaning processes even with mild alkaline formulations. For the first time, the mode of action of the proteins was tracked and measured in real time by means of a quartz crystal microbalance during application of a glass cleaner formulation. It was found that during the cleaning process most probably multilayer of proteins and surfactants are formed on the cleaned surface. These layers create an effective easy-to-clean effect during the repeated application of the glass cleaner. Even after extensive rinsing with pure water, a compact protein film remains on the surface which acts as an effective barrier against resoiling. The easy-to-clean effect of this protective layer was also confirmed macroscopically with several exemplary household cleaner formulations according to the IKW method for all-purpose cleaners on a Wet Abrasion Scrub Tester.

New Laundry Carboxymethyl Cellulose with Significantly Improved Performance
Steven Patterson, Procter & Gamble
Spoken Language: English Category: Home Care / Cleaning Agents Carboxymethyl cellulose (CMC) has long been used in laundry detergent applications as a cotton anti-redeposition agent. The correlation between polymer molecular weight (and hence solution viscosity), degree of carboxymethyl substitution (DS) and observed anti-redeposition benefit has been studied by several groups and it is generally agreed that molecular weight and degree of substitution must be balanced to achieve good water solubility while retaining good affinity for cotton surfaces in the wash. In the case of wood-pulp derived carboxymethyl cellulose, this involves a DS of 0.4-0.7, with some authors reporting a sharp drop in performance at DS > 0.7. In recent years, developments in the synthesis and production of carboxymethyl cellulose have led to improved control of the regioselectivity of the carboxymethylation reaction. This has enabled ‘blocky’ polymers to be produced where the carboxymethyl groups are clustered together on the cellulose backbone rather than randomly distributed. This can also influence the ratio of substitution at the three available hydroxyl groups (C2, 3, 6) in the glucose repeating unit. Through modeling the carboxymethyl cellulose molecular structure, especially with regards to solution viscosity, DS and degree of blockiness (DB), we have identified a new grade of this polymer which significantly outperforms the standard detergent grade CMC material. The increased performance of the new polymer can be explained by the combination of its high degree of substitution (and resulting impact on fabric surface charge) and high degree of blockiness, which enables such a high DS polymer to adsorb onto cotton resulting in high levels of surface charge, as measured by zeta potential. An added advantage of the new polymer is increased robustness to cellulase leading to strong anti-redeposition performance when combined with a cleaning cellulase enzyme.
Spoken Language: English Category: Home Care / Other (Biosurfactants) Biosurfactants are rapidly expanding their market share due to favourable characteristics for use in personal care and household cleaning products. In particular, many biosurfactants have antimicrobial, moisturizing, controllable foaming and are 100% biodegradable. At present biosurfactants tend to be used in high end products due to their relatively high production cost. We present results from the development of a novel gravity based integrated separation technique for the controlled production and in situ separation of glycolipid biosurfactants during fermentation. This technique has enabled us to increase productivity to >5.5 g l-1 h-1 and titer to > 900 g l-1, initially for sophorolipid biosurfactants. We have demonstrated our technology with an additional biosurfactant, mannosylerythritol lipids, and identified its suitability with a range of biosurfactants, enabling dramatic reductions in production costs. We have formed a consortium of companies and researchers, able to develop and manufacture cost effective biosurfactants for a given product requirement, and are providing samples of our products for testing. This technology platform is set to make biosurfactants an economically viable alternative to traditional surfactants across a range of industries, including the home cleaning sector where sophorolipids are already in commercial use.

Fluidized Bed Processing Options for Value Added Product Forms
Katja Oppermann, Glatt Ingenieurtechnik GmbH
Spoken Language: German Category: Home Care / Detergents Development of innovative products requires state-of-the-art technologies. Fluidized and spouted bed processes offer almost unlimited possibilities in terms of particle structure of dry product forms. Most of these possibilities are strongly linked to drying or solidification mechanisms. Such processes are usually multiphase problems and must be designed accurately. Optimal evaluation of process conditions and parameters as well as material properties allows to directly design particulate products like homogeneous grains, porous agglomerates or layered products having hierarchical structures. With making use of this knowledge innovative products can be developed and manufactured effectively. That offers benefits for producers as well as for users. For instance, spray agglomeration makes products easier and more safe to handle, better to dose, better in homogeneity. Using fluidized bed agglomeration technology, stability, functionality and processability as well as instant properties can be significantly improved. Main fields of application are besides cosmetics, detergents and cleansers the food, feed and pharmaceutical industry as well as fine chemicals, where high performance products are needed. The contribution shows actual status of research activities at Glatt applying various processing principles, creating different particle structures and using different technical configurations of plants. In addition, various drying principles and technologies will be presented in order to achieve optimum product performance. The basis of every product development is the comprehensive knowledge of the targeted application, which is used to select suitable process options to realize certain particle properties. Industrial case studies of sodium percarbonate, enzymes, aromas, detergents and surfactants illustrate the purpose of various process options and machine configurations based on fluid bed technology.

Cleaning Process with Indication Means
Dr. Dipl.-Phys. Wolfgang Thimm, E.G.O. Elektro-Gerätebau GmbH
Spoken Language: German Category: Home Care / Other (Technology & Machinery: Cleaning Household Appliances) The idea of a cleaning process with indication means will be presented. In a cleaning process for dishes, laundry or similar things the items will be cleaned in a first cleaning section for a certain time. In a second step indication means will be added to the items. The indication means are created in a way that the attach to dirt. In a third step the indication means will be detected with a sensor to determine which of the items are already clean enough and which of the items contain still dirt, which needs to be removed. In a fourth step the items which still contain dirt will be cleaned another time. The cleaning process targets to save energy, water consumption and especially time. Especially the detection of dirt avoids that the cleaning process will be continued although the items are already clean enough. Literature: Thimm, DE 10 2016 202 267 A1, 2017

Novel Multifunctional Magnesium-Based Carrier for Facile Handling of Automatic Dishwashing Actives
Dr. Tobias C. Keller, Omya International AG
Spoken Language: German Category: Home Care / Detergents Hydromagnesite (HM) is a naturally occurring mineral consisting of hydrated basic magnesium carbonate. Through appropriate crystal growth control and processing, it can be synthesized as platelet-shaped crystals arranged into an accessible, house of cards-like structure. The extraordinary porosity of the resulting material makes HM an attractive carrier that can be loaded with up to 2.5 times its own weight worth of fluids while remaining a free-flowing powder. This is of great advantage in homecare applications, where active substances such as automated dishwashing (ADW) surfactants often come in the form of highly viscous, wax-like, and/or sticky fluids. To avoid the connected difficulties in handling, the actives are loaded onto an HM carrier, transforming them into a powder that can be readily incorporated into solid-state formulations such as granules or tabs. In this contribution, we pioneer the application of HM as carrier for homecare applications. Through a detailed characterization of the physico-chemical properties of different HM samples, the structure-performance relationships describing the loading and release properties are revealed. The high-surface of the carrier promotes the rapid dissolution of loaded actives, particularly for highly viscous products at low temperatures. On top of that, we provide evidence that hydromagnesite can reduce the Calcium hardness of water by actively scavenging Ca2+ ions via the ion-equilibrium, while simultaneously acting as seed crystal. The applicability of the attained results in ADW has been confirmed in build-up trials, where a high quantity of HM (10 wt.%) was added to a commercial dishwashing formulation. Comparison with the non-modified formulation indeed revealed an improved performance. The attained results confirm that HM are attractive carriers for actives in homecare applications, which are particularly well-suited for ADW due to their unique multifunctionality.
