This book was released on 2015 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The test described in this Test Guideline allows the identification of corrosive chemical substances and mixtures and it enables the identification of non-corrosive substances and mixtures when supported by a weight of evidence determination using other existing information. The test protocol may also provide an indication of the distinction between severe and less severe skin corrosives. This Test Guideline does not require the use of live animals or animal tissue for the assessment of skin corrosivity. The test material (solid or liquid) is applied uniformly and topically to a three-dimensional human skin model, comprising at least a reconstructed epidermis with a functional stratum corneum. Two tissue replicates are used for each treatment (exposure time), and for controls. Corrosive materials are identified by their ability to produce a decrease in cell viability below defined threshold levels at specified exposure periods. Coloured chemicals can also be tested by used of an HPLC procedure. The principle of the human skin model assay is based on the hypothesis that corrosive chemicals are able to penetrate the stratum corneum by diffusion or erosion, and are cytotoxic to the underlying cell layers.

Download or read book Live Cell Assays written by Christophe Furger and published by John Wiley & Sons. This book was released on 2016-07-14 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell assays include all methods of measurements on living cells. Confined for a long time to research laboratories, these emerging methods have, in recent years, found industrial applications that are increasingly varied and, from now on, regulatory. Based on the recent explosion of knowledge in cell biology, the measurement of living cells represents a new class of industry-oriented research tests, the applications of which continue to multiply (pharmaceuticals, cosmetics, environment, etc.). Cellular tests are now being positioned as new tools at the interface between chemical methods, which are often obsolete and not very informative, and methods using animal models, which are expensive, do not fit with human data and are widely discussed from an ethical perspective. Finally, the development of cell assays is currently being strengthened by their being put into regulatory application, particularly in Europe through the REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) and cosmetic directives.

Download or read book OECD Guidelines for the Testing of Chemicals Section 4 Test No 498 In vitro Phototoxicity Reconstructed Human Epidermis Phototoxicity test method written by OECD and published by OECD Publishing. This book was released on 2023-07-04 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skin phototoxicity (photoirritation) is defined as an acute toxic response elicited by topically or systemically administered photoreactive chemicals after the exposure of the skin to environmental light. The in vitro reconstructed human epidermis phototoxicity test (RhE PT) is used to identify the phototoxic potential of a test chemical after topical application in reconstructed human epidermis (RhE) tissues in the presence and absence of simulated sunlight.
