Book excerpt: Hydroquinone has a variety of uses principally associated with its action as a reducing agent which is soluble in water. It is a major component in most photographic developers for film and paper, and is used as a topical application in skin whitening to reduce the colour of skin. In this book, the authors present current research in the production, uses and health effects of hydroquinone. Topics discussed include the cellular effects of hydroquinone; the involvement of cigarette smoke-related hydroquinone in the pathogenesis of age-related macular degeneration; hydroquinone solubility and separation processes; the transport and transfer processes of poly(o-aminophenol)film electrodes in the presence of the hydroquinone/p-benzoquinone redox couple and the detection of thiols using hydroquinone on gold surfaces.

Download or read book Hydroquinone written by M. Gillner and published by . This book was released on 1994 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluates the risks to human health and the environment posed by exposure to hydroquinone, a chemical found in natural form in a number of plants and animals. Hydroquinone is manufactured for a large variety of commercial applications, including use as a developer in black-and-white photography in the production of medical and industrial X-ray films, in the manufacture of rubber antioxidants and antiozonants and antioxidants for food preservation and as a chemical intermediate for the production of agrochemicals and performance polymers. Hydroquinone and products containing hydroquinone are used in cosmetics and medical skin preparations as a depigmentation agent to lighten small areas of hyperpigmented skin and to treat various other disorders of pigmentation. The most extensive section evaluates studies of toxic effects in experimental animals and in vitro test systems. Particular attention is given to recent studies indicating that co-exposure to hydroquinone and various other phenolic compounds can greatly potentiate the toxic effects of the individual compounds causing cytotoxic, immunotoxic, and genotoxic effects. Although data from human studies were judged inadequate to evaluate carcinogenic potential, the report notes a well-documented association between exposure to hydroquinone and various skin disorders. Long-term exposure to airborne hydroquinone has been observed to cause a range of ocular disorders. Citing evidence that skin-lightening creams containing hydroquinone are frequently inadequately labeled and contain concentrations exceeding the permitted limit the report recommends that over-the-counter sale of these products be restricted. The report also calls for the development of health education programs to discourage the use of these creams for whole body skin lightening.

Download or read book Materia Medica of New and Old Homeopathic Medicines written by David S. Riley and published by Springer. This book was released on 2017-12-21 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: David S. Riley’s interest in the history, methodology and results of homeopathic drug provings began with his exposure to homeopathy in 1988 and his later study at the Hahnemann College of Homeopathy in Albany, California. The homeopathic drug provings published here are the result of his investigation of the research methods associated with homeopathic drug provings and contemporary research methodology. Dr. Riley has developed explicit and transparent research tools for (1) symptom selection criteria, (2) electronic data collection, and (3) blinding to reduce bias. These homeopathic drugs provings follow good clinical practice research guidelines (GCP) and incorporate the guidelines suggested by Dr. Samuel Hahnemann more than 200 years ago
Download or read book Active Ingredients Used in Cosmetics written by Council of Europe. Committee of Experts on Cosmetic Products and published by Council of Europe. This book was released on 2008-01-01 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ingredients are used in cosmetics to give them specific properties. Certain ingredients, so called active ingredients, may produce pharmacological or toxic effects under certain conditions. Cosmetic products containing such ingredients may pose a health risk both because of their potential toxicity and because they may mask underlying serious diseases and consequently cause a dangerous delay in diagnosis and treatment.The objective of this study is to give safety information on certain active ingredients which give raise to toxicological concerns and for which restrictions of use in cosmetics should be considered.Monographs were prepared for 45 active ingredients for which no specific regulations exist including, inter alia, information about uses, properties, a risk evaluation of the use in cosmetic products considering as toxicological endpoints both systemic and local effects. Each monograph includes a bibliography, conclusions and recommendations.The study complements a series of three volumes containing monographs about the safety of certain natural ingredients used in cosmetics and will serve as a useful reference in the field, for health authorities, manufacturers and health professionals in particular.
Download or read book Light induced Electron Transfer Between Chlorophyll and Hydroquinone and the Effect of Oxygen and Beta Carotene written by Eiji Fujimori and published by . This book was released on 1966 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light-induced electron spin resonance (ESR) absorption is not observed in degassed benzene solutions of chlorophyll a with hydroquinone. In the presence of methanol, however, the characteristic hyperfine pattern of p-benzosemiquinone ion radical is formed. This photoreduction of chlorophyll by hydroquinone is enhanced apparently by a small amount of triethylamine and inhibited by beta-carotene.
