About this title

Review

Aims to teach the important principles behind surfactant aggregation and how these can be applied to the various systems which result from such aggregation. - British Book News; In summary, Surfactant Aggregation is a valuable new book. It could serve as a reference or textbook in advanced chemistry courses and it will provide a firm foundation for dealing with application problems - Polymer News; Mathematics has been kept to a minimum, the book is compact, easy to read, has adequate references and is well illustrated with clear diagrams and data... This book is the best reference book available on surfactant theory and should be essential reading for those involved in the manufacture or use of surfactants. - Chemistry in Britain; ...a broad ranging and concise account of surfactants generally. Although the approach is basically one of the fundamental science underlying the behaviour of surfactants, connections are made throughout with industrial applications and living systems. Readers in academia will value this connection. Those in industry will use the book to improve their understanding of the basic principles and as a handy reference for unfamiliar surfactant topics. It will give an ideal overview with both breadth and depth for students and others new to surfactants. Attention to detail is impressive yet the writing style is straightforward and easy to read. References are plentiful and illustrations are helpful...strongly recommended for anyone with an interest of involvement in surfactants - Journal of the Oil and Colour Chemists Association
