sensitiser - Dictionary definition and meaning for word sensitiser Definition (noun) (chemistry) a substance other than a catalyst that facilitates the start of a catalytic reaction Se hela listan på ed.ac.uk The packaging of products containing 0.1% of a sensitizer must bear the inscription “Contains ‘name of sensitizer’. May produce an allergic reaction.” The aim is to protect individuals already sensitized by providing information which enables them to avoid products containing ingredients which may elicit their allergy. Substances can be classified as skin sensitisers if there is evidence from experimental tests or in humans that the substance can lead to sensitisation by skin contact. From information in the Classification and Labelling Inventory, there are over 14 000 substances on the EU market with some indication of a skin sensitising concern. 7 exposure to substances. Photosensitisation is potentially important but its mechanism of 8 action is poorly understood, and it is not discussed in this document.

9 Definition of skin and respiratory sensitisation 10 A skin sensitiser is an agent that will lead to an allergic response in susceptible 11 individuals following skin contact. Sensitizers are chemical substances that can cause sensitization in the lungs (respiratory sensitizers) or to the skin (skin sensitizers) after exposure. Once individuals are sensitized, they can have severe reactions to further exposure, even if the exposure quantity is below the regulated occupational exposure limits. GHS Classification Criteria for Skin Sensitization.

Europe. Repeated exposure to the sensitiser, impaired skin barrier like in Given the special risks that substances classifiedas carcinogenic, mutagenic or toxic for packaging andlabelling of dangerous substances (2), may entail for human or toxic for reproduction categories 1, 2 or 3, or as a respiratory sensitiser.
Sensitizer or sensitiser may refer to: . Chemical sensitizer, a chemical that causes allergic reaction in normal tissue after exposure; Explosive sensitizer, a chemical that promotes the rate of propagation of an explosive; see Chemical explosive#Sensitizer
Skin Sensitizer A substance that will induce an allergic response following skin contact. The definition for "skin sensitizer" is equivalent to "contact sensitizer". The authors suggested that the probable determinants of sensitization are the N(CH 3) 2 or the N(C 2 H 5) 2 moieties in the para position of the benzene ring structure and that cross-reactivity is limited to substances with amino groups substituted with at least two alkyl groups (see Figure 1). GHS classifies a substance as a skin sensitizer if: (a) “there is evidence in humans that the substance can lead to sensitization by skin contact in a substantial number of persons,” or (b) “there are positive results from an appropriate animal test” . When considering the hierarchy of controls, this would mean either substituting for a non-sensitizing product or using technical controls to contain the product as much as possible.
Medical definition of sensitizer: one that sensitizes: as. b: a substance that sensitizes the skin on first contact so that subsequent contact causes inflammation A sensitizer is defined by OSHA as "a chemical that causes a substantial proportion of exposed people or animals to develop an allergic reaction in normal tissue after repeated exposure to the chemical." Definition of sensitizer in the Definitions.net dictionary. Meaning of sensitizer.
It establishes the set of criteria to which a drug substance or drug product should conform to be considered acceptable for its intended use.

In crystallography, atomic packing factor (APF), packing efficiency, or packing fraction is the fraction of volume in a crystal structure that is occupied by constituent particles. It is a dimensionless quantity and always less than unity.
