Essential Oils: Contact Allergy and Chemical Composition

Essential Oils: Contact Allergy and Chemical Composition provides a full review of contact allergy to essential oils along with detailed analyses of the chemical composition of essential oils known to cause contact allergy. In addition to literature data, this book presents the results of nearly 6,400 previously unpublished sample analyses, by far the largest set of essential oils analyses ever reported in a single source of scientific literature. Covering 91 essential oils and two absolutes, the book presents an alphabetical list of all 4,350 ingredients that have been identified in them, a list of chemicals known to cause contact allergy and allergic contact dermatitis, and tabular indications of the ingredients that can be found in each essential oil. The book discusses contact allergy and allergic contact dermatitis for each of the oils and absolutes, sometimes able to provide only one or two reports but drawing upon considerable amounts of literature in other cases, such as with tea tree oil, ylang-ylang oil, lavender oil, rose oil, turpentine oil, jasmine absolute, and sandalwood oil. While limited information on the main components and their concentrations would be enough for most dermatologists, this book gives extensive coverage not only to improve levels of medical knowledge and quality of patient care, but also for the benefit of professionals beyond clinical study and practice, such as chemists in the perfume and cosmetics industries, perfumers, academic scientists working with essential oils and fragrances, aromatherapists, legislators, and those involved in the production, sale, and acquisition of essential oils.

Anton C. de Groot, 1980-2002 dermatologist in private practice in two hospitals in ‘s-Hertogenbosch, The Netherlands. PhD 1988: Adverse Reactions to Cosmetics. Author of over 500 publications including 70 book chapters and 14 books, of which 4 are international (mainly for dermatologists) and 10 in Dutch for general practitioners, medical students, skin therapists, podiatrists/pedicures and (parents of) patients with atopic dermatitis. Regularly teaches dermatology to medical students at the University of Groningen. Member of the Editorial Board of the journal Dermatitis (specialized in contact allergy). Co-founder and former 10-year Editor-in-Chief of the Dutch Journal for Dermatology and Venereology. Anton C. De Groot is an honourary member of the American Contact Dermatitis Society, he was specifically recognised for his contributions to the field through his series Monographs in Contact Allergy Further information can be found on the author's website www.patchtesting.info Erich Schmidt completed his studies in business economics at the Landshut University of Applied Sciences, Bavaria, Germany. Since he first began working with essential oils in a middle-sized German company that designed and produced perfume compositions, his interest in analyzing the compositions of essential oils increased. He eventually established an analytical laboratory and as the use of aromatherapy grew in Germany, he provided information about risks, safety evaluation, and genuineness of essential oils. In 1995 he was chosen as the German responsible representative of the International Organization for Standardization’s Technical Committee 54, Essential Oils. Since 2005, he has authored or coauthored more than 90 publications in numerous journals, and contributed two chapters to the Handbook of Essential Oils.

Review :
" 'Essential Oils – contact allergy and chemical composition'... can be very helpful not only to dermatologists, but also for other professionals, such as chemists working in the perfumery and cosmetic industry, academic scientists working with essential oils and fragrances, aromatherapists, legislators, and those involved in the production, sale, and acquisition of essential oils. Unique features of the book are included in the final chapters: A table of all chemicals which can be found in each essential oil with concentrations. An alphabetical list of 4,350 ingredients identified in the oils and absolutes, with their synonyms and CAS numbers, specifying in which oils each chemical can be present. A book that represents a 'must to have' for all of us involved in the fascinating world of essential oils." – Luigi Mondello, for the Journal of Essential Oil Research, November 2016, http://dx.doi.org/10.1080/10412905.2016.1245825. ‘Every dermatologist who patch tests his or her dermatitis patients with more than only the European baseline series, should have, according to the reviewer, a copy of this book. It will be the standard for this subject for a very long time. The book should also be useful to academic scientists working in the field of essential oils and fragrances, cosmetic chemists, analytical chemists, perfumers, aromatherapists, and legislators.’ – T.L. Diepgen, Heidelberg, for Dermatologie in Beruf und Umwelt, 2017;65(1):41. ‘This interesting book, written by two well-known scientists, results a fundamental tool to be kept in the library as consultant mean useful not only for all students of the chemical and medical community, but also for dermatologists and cosmetic chemists, who wish to know the chemical composition of the more known essential oils and understand their capacity to cause possible contact allergy. … I think that also this book will represent a milestone for Dermatologists and Cosmetic Chemists. This is my hope.’ – P. Morganti, J. Appl. Cosmetol., 34. 158-160 (July / December 2016).
