Surfactants are in everyday products such as detergents, foodstuffs, and cosmetics. Their molecules have one part which is water soluble and another which is not. This gives them two valuable properties: they adsorb at surfaces, and they stick together in water. This book treats the physical chemistry and physics underlying surfactants.
Surfactants... today you have probably eaten some, or rubbed others on your body. Plants, animals (including you) and microorganisms make them, and many everyday products (e.g. detergents, cosmetics, foodstuffs) contain them. Surfactant molecules have one part which is soluble in water and another which is not. This gives surfactant molecules two valuable properties: 1) they adsorb at surfaces (e.g. of an oil droplet in water), and 2) they stick together (aggregate) in water. The aggregates (micelles) are able to dissolve materials not soluble in water alone, and adsorbed surfactant layers, at the surfaces of particles or (say) oil droplets in water, stop the particles or drops sticking together. This is why stable emulsions such as milk do not separate into layers. This book treats the basic physical chemistry and physics underlying the behaviour of surfactant systems.
In this book, you will first learn about some background material including hydrophobic hydration, interfacial tension and capillarity (Section I). Discussion of surfactant adsorption at liquid/fluid and solid/liquid interfaces is given in Section II, and includes thermodynamics of adsorption, dynamic and rheological aspects of liquid interfaces and the direct characterisation of surfactant monolayers. In Section III, a description is given of surfactant aggregation to give micelles, lyotropic liquid crystals, microemulsions and Winsor systems. There follows a discussion of surface forces and the way they confer stability on lyophobic colloids and thin liquid films (Section IV). Various dispersions stabilised by adsorbed surfactant or polymer (including solid in liquid dispersions, emulsions and foams) are considered in Section V. The wetting of solids and liquids is explored in Section VI. Like surfactants, small solid particles can adsorb at liquid/fluid interfaces, form monolayers and stabilise emulsions and foams. Such behaviour is covered in Section VII. It is assumed the reader has a knowledge of undergraduate physical chemistry, particularly chemical thermodynamics, and of simple physics. Mathematics (elementary algebra and calculus) is kept at a level consistent with the straightforward derivation of many of the equations presented.
About the Author: Bob Aveyard is Professor Emeritus at the University of Hull, where he was Personal Chair in Colloid and Surface Chemistry. He was awarded Colloid and Interface Science Group Medal of the Royal Society of Chemistry in 1994 for "contributions to colloid and surface chemistry". Aveyard has 40 years experience teaching at undergraduate, postgraduate and postdoctoral levels, contributing to courses for industrial researchers, and directing research sponsored by Government and major British and overseas companies. He spent a sabbatical year with BP Research at Sunbury (1987-1988). He earned his Ph.D. at Sheffield University, and did postdoctoral research in the Department of Colloid Science at Cambridge University.

Additional Delivery Information (and some really important bits):
UK Delivery
Orders for delivery in the UK are normally despatched by Royal Mail, using the RM 48 Tracked Service with most orders delivered to you within a few days of placing your order with us. For larger parcels, Courier and Signed For delivery services may be used. Signed Books are shipped in our specially made book mailing cartons, with the books themselves wrapped in paper to protect them. Sometimes we may ship your order in several parts, particularly if you have 'Pre-Order' titles in your order or titles which are held in stock with our publishing partners.
The Really Important Bit: Because we use tracked, courier and signed for delivery services, please use an address at which your parcel can be received during the normal working day, for example, you may want to have your order delivered to your work address if you're not at home during the day.
First Item @ £3.75 (sometimes a shipping supplement may be added for particularly heavy books or specific postcodes*)
2 Items & over @ £5.00 in total
Another Really Important Bit: There are a number of Postcodes in the UK for which we will need to charge a shipping supplement, this will be calculated once we know the size and weight of the shipment. For these orders we will contact customers to agree a suitable and economic method of shipping. There may also be additional time required for delivery to some areas of the United Kingdom. Where possible, we will ship book orders (under 2kg) by Royal Mail to all UK postcodes. Large multiple book orders and books over 2kg are often shipped via APC Overnight or similar, regardless of Postcode.

First Item @ £15.00 (sometimes a shipping supplement will be added for particularly heavy books)
2 Items & over @ £30.00 in total
A really, really important Brexit bit: From 1st January 2021 shipments to EU addresses may incur additional costs which could be requested by Fed Ex at the time of delivery. These costs may vary from country to country and are not within our control and will be in addition to the costs paid to us for your delivery.
