This book was released on 2000-10-18 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers the different concepts of hydrophile-lipophile balance (HLB) of surfactants and solid particles and the main physicochemical properties of surfactant and solid interfaces which are used to definite the hydrophile-lipophile balance. The book comprehensively analyses all interfacial and bulk properties of surfactants used for the determination of HLB (such as interfacial tension, distribution coefficient, adsorption, surface pressure, surfactants solubility, structure characteristics, distribution between heteropolar phases, micellar formation, chromatographic characteristics, phase separation in emulsions, phase inversion temperature, formation of three phase systems).The central point of the book is the energetic interpretation of the balance, i.e. the hydrophile-lipophile ratio. At the same time the HLB-number systems of Griffin and Davies and other independant methods of the hydrophile-lipophile balance definitions are discussed: PIT, polarity indexes, surfactant affinity difference etc. The possibility of application of the different characteristics of the hydrophile-lipophile balance as a criterion of phase inversion in emulsions and microemulsion systems water-oil-surfactant are considered.For the first time the different methods of the hydrophile-lilophile balance definition for solid particles in compact and dispersed form are suggested by the author. The use of hydrophile-lipophile characteristics of solid particles as a criterion of phase inversion in emulsion stabilisation and for other applications is discussed.

Download or read book Surfactants written by Bob Aveyard and published by Oxford University Press, USA. This book was released on 2019 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characteristically, surfactants in aqueous solution adsorb at interfaces and form aggregates (micelles of various shapes and sizes, microemulsion droplets, and lyotropic liquid crystalline phases). This book is about the behaviour of surfactants in solution, at interfaces, and in colloidal dispersions. Adsorption at liquid/fluid and solid/liquid interfaces, and ways of characterizing the adsorbed surfactant films, are explained. Surfactant aggregation in systems containing only an aqueous phase and in systems with comparable volumes of water and nonpolar oil are each considered. In the latter case, the surfactant distribution between oil and water and the behaviour of the resulting Winsor systems are central to surfactant science and to an understanding of the formation of emulsions and microemulsions. Surfactant layers on particle or droplet surfaces can confer stability on dispersions including emulsions, foams, and particulate dispersions. The stability is dependent on the surface forces between droplet or particle surfaces and the way in which they change with particle separation. Surface forces are also implicated in wetting processes and thin liquid film formation and stability. The rheology of adsorbed films on liquids and of bulk colloidal dispersions is covered in two chapters. Like surfactant molecules, small solid particles can adsorb at liquid/fluid interfaces and the final two chapters focus on particle adsorption, the behaviour of adsorbed particle films and the stabilization of Pickering emulsions.--Provided by publisher.
Download or read book Pharmaceutical Dosage Forms and Drug Delivery written by Ram I. Mahato and published by CRC Press. This book was released on 2017-11-22 with total page 667 pages. Available in PDF, EPUB and Kindle. Book excerpt: Completely revised and updated, this third edition of Pharmaceutical Dosage Forms and Drug Delivery elucidates the basic principles of pharmaceutics, biopharmaceutics, dosage form design, and drug delivery – including emerging new biotechnology-based treatment modalities. The authors integrate aspects of physical pharmacy, chemistry, biology, and biopharmaceutics into drug delivery. This book highlights the increased attention that the recent spectacular advances in gene therapy and nanotechnology have brought to dosage form design and drug delivery. With the expiration of older patents and generic competition, the biopharmaceutical industry is evolving faster than ever. Apart from revising and updating existing chapters on the basic principles, this edition highlights the emerging emphasis on drug discovery, antibodies and antibody-drug conjugates as therapeutic moieties, individualized medicine including patient stratification strategies, targeted drug delivery, and the increasing role of modeling and simulation. Although there are numerous books on pharmaceutics and dosage forms, most cover different areas of the discipline and do not provide an integrated approach. The integrated approach of this book not only provides a singular perspective of the overall field, but also supplies a unified source of information for students, instructors and professionals, saving their time and money.
