Preface

In 2001, we published the first edition of the Handbook of Cosmetic Science and Technology with 71 chapters written by leading experts in their field of cosmetology, who have largely contributed to the international success of the Handbook.

Since publication, comments were collected from readers and reviewers to detect improvements that could be added to this edition. Most feedback was highly positive as illustrated by some of the following: ‘‘ . . . excellent overall coverage of most aspect of cosmetology . . . ;'' ‘‘ . . . contains a lot of scientific information about the physical properties of cosmetic ingredients . . . ;'' ‘‘ . . . an excellent balance of authors from major cosmetic houses and with many academic leaders coming from a huge range of countries provides an international view of cosmetics . . . ;'' ‘‘ . . . an extensive and comprehensive index can be considered as a measure of the book's value . . . .'' This feedback was highly appreciated and motivated us in continuing the adventure and in initiating a second edition that, we hope, will receive the same success as the first one.

Like in all first editions, a few improvements were suggested and were taken into account; it was mainly to develop a more systematic chapter organization as well as making some chapters more accessible and readable for nonexpert readers. Furthermore, cosmetology is, today, a fast moving science with new ingredients, new technologies, and changing regulations. Thus, it was necessary to publish a second edition to remain an up-to-date and practical Handbook of Cosmetic Science and Technology.

The objectives pursued with the second edition are multiple. Most chapters, recognized as essential for the cosmetologist, were kept but simplified, reviewed for overlapping with others, made more readable, and mainly updated with new developments or new anticipated trends. Some chapters had to be largely revisited such as in Part VI: Regulatory and Safety Considerations, that is probably the fastest changing field. Many chapters were added to cover new ingredients and technologies identified by the editors. That is mainly evident in Part III: Cosmetic Ingredients where many new, active, and promising ingredients have emerged. Testing the products has also improved, in terms of physicochemistry as well as in cell culture models or in skin measuring techniques. Chapters were added or re-designed to reflect such an evolution. Finally, some gaps in the first edition were filled with chapters on additional product types, adding more emphasis on ethnic skin and its differences in cosmetics requirements.

The editors are grateful to the authors, who contributed to the previous edition and updated their chapters, and to the new authors who agreed to share their experiences on emerging subjects, sometimes with unpublished information.

Finally, it is anticipated that future editions will benefit in the same way as this edition, from readers' suggested additions, deletions, and improvements.
