Download or read book Rheology Essentials of Cosmetic and Food Emulsions written by Rüdiger Brummer and published by Springer Science & Business Media. This book was released on 2006-05-27 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cosmetic emulsions exist today in many forms for a wide variety of applications, including face and hand creams for normal, dry or oily skin, body milks and lotions, as well as sun-block products. Keeping track of them and their properties is not always easy despite informative product names or partial names (e.g. hand or face cream) that clearly indicate their use and properties. This practical manual provides a detailed overview that describes the key properties and explains how to measure them using modern techniques. Written by an expert in flows and flow properties, it focuses on the application of rheological (flow) measurements to cosmetic and food emulsions and the correlation of these results with findings from other tests. Beginning with a brief history of rheology and some fundamental principles, the manual describes in detail the use of modern viscometers and rheometers, including concise explanations of the different available instruments. But the focus remains on practical everyday lab procedures: how to characterize cosmetic and food emulsions with different rheological tests such as temperature, time, stress and strain, both static and dynamic. Also the critical topic of how the results correlate with other important product characteristics, for instance, skin sensation, pumping performance, stability etc. is carefully explored. Many pictures, illustrations, graphs and tables help readers new to the measurement of cosmetic emulsions in their daily work as well as to the more experienced who seek additional special tips and tricks.

This book was released on 2011-09 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surfactants are important in our daily life because they were widely used in household products, cosmetic, food and pharmaceutical industries as emulsifier, wetting agent, cleanser, foaming agents, solubilizers, conditioners, thickener and also to produce emollients. Therefore, nature of the surfactants is relatively important and is expected to be human friendly as the surfactants will be directly contacted with human. In recent years, biosurfactants such as glycolipids have drawn a large attention in the industrial applications especially in cosmetic and pharmaceutical industries. In this book, sucrose fatty acid ester which is a non-toxic and human friendly glycolipid surfactant was used in the preparation of olive oil-based emulsions for cosmetic and pharmaceutical applications. The results provide the information on the effect of the emulsion droplet size to the stability and rheological properties such as viscoelastic and viscosity of the emulsions.

Available in PDF, EPUB and Kindle. Book excerpt: Emulsions occur either as end products or during the processing of products in a huge range of areas including the food, agrochemical, pharmaceutical, paint and oil industries. Despite over one hundred years of research in the subject, however, a quantitative understanding of emulsions has been lacking. Modern Aspects of Emulsion Science presents a comprehensive description of both the scientific principles in the field and the very latest advances in research in this important area of surface and colloid science. Topics covered include emulsion formation, type, stability (creaming, flocculation, ripening, coalescence), monodisperse and gel emulsions, and applications. Emphasis has been placed on relating the chemistry of the surfactant or protein adsorbed at the oil-water interface to the principles of the physics involved in the bulk emulsion property. The book has been written by a collection of the world's leading experts in the field, and covers both experimental and theoretical approaches. Modern Aspects of Emulsion Science fills a real gap in the market, being the only book of its kind in print. As such it will prove essential reading for graduates and researchers in this subject, in both academia and industry.

Download or read book Large Amplitude Oscillatory Shear (LAOS) Rheology of Pickering Emulsions written by Kunal Choudhuri and published by . This book was released on 2016 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emulsions are a class of disperse systems consisting of two immiscible liquids. The liquid droplets (the disperse phase) are dispersed in a liquid medium (the continuous phase). In order to disperse two immiscible liquids, a third component is required, namely the emulsifier. The choice of emulsifier is crucial not only for the formation of the emulsion but also for its long term stability. Pickering emulsions are emulsions of any type, either oil-in-water (o/w), water-in-oil (w/o), or even multiple, stabilized by solid particles in place of surfactants. Pickering emulsions are named after S.U. Pickering whose paper is considered the first report of o/w emulsions stabilized by solid particles adsorbed at the surface of oil droplets. The 'surfactant-free' character of these emulsions makes them attractive to several applications fields, in particular cosmetic and pharmaceutical applications where surfactants often show adverse effects.Typically in Pickering emulsions, the droplet interfaces are stabilized by the presence of particles. These particles can modify the flow properties or rheology of the emulsions by modifying the interaction between the droplets. Hence an understanding of emulsion flow properties is of fundamental interest and of value for many applications. This research work is focused on studying and analyzing the Large Amplitude Oscillatory Shear (LAOS) Rheology of Pickering emulsions stabilized by Poly(methyl methacrylate) or PMMA particles. With the help of the MITlaos framework, intra-cycle nonlinearities such as strain stiffening/softening and shear thickening/thinning have been studied for these Pickering emulsions. Firstly, the repeatability aspect of the experimental protocol has been studied followed by the LAOS analyses at three different strain percentages. The analyses have been compared for the slip v/s no-slip cases as well and the elastic and viscous nonlinearities have been quantified. Finally, the prospect of analyzing the LAOS Rheology at two different volume fractions of particles have been performed. In these experiments, elastic and viscous nonlinearities are not observed at low strains but they become more prominent as the strain percentages are increased. Through the use of Chebyshev decomposition of the stress response and alternate moduli to quantify the nonlinearities, we gain physical insight about the sample behavior as it is subjected from low to higher strains/strain-rates. These physical insights can be obscured by conventional rheology characterization test protocols like Small Amplitude Oscillatory Shear (SAOS) techniques.Another aspect of the thesis work is aimed to combine rheology with imaging using a 20X objective lens on the Discovery Hybrid Rheometer (TA-Instruments, DHR-3). This imaging allowed me to correlate between the droplet deformations and the large amplitude rheology. At low strains, the droplet deformations are reversible, as observed from the comparison of the images taken before and after the sample is subjected to shear. At large strains, however, the droplet deformations are irreversible. As the emulsion yields from being 'solid-like' to 'liquid-like' in response to the increasing strain, the permanent droplet deformations become kore prominent. The observations of the imaging studies using the DHR are complemented by the results of the LAOS analyses.
