“…In particular one study did yield ambiguous results, (Stimulation Index (SI) 30 scores ranging 2.0-3.2), likely due to local inflammatory reactions elicited by the intradermal injection of the additive; on the contrary, the other study was fully negative (SI range 0.41-1.05). A clinical case study carried out in 1988, available only as an abstract, could not be evaluated due to the limited information reported (Senff et al, 1988).…”

Selenium is an essential trace element for vertebrates, involved in a series of vital metabolic functions. Sodium selenite is a safe and efficacious source of selenium for all animal species/categories. The use of sodium selenite as a source of selenium in animal nutrition is safe for the consumer, provided that the total maximum authorised content of selenium in complete feed is respected. The additive is an irritant to the skin, eyes and mucosae, whereas it is not a skin sensitiser. Systemic exposure to selenium could result from dermal contact. Users/workers handling the additive would be exposed to selenium by inhalation at levels which constitute a risk. The use of sodium selenite in animal nutrition up to the maximum authorised content in feed would not raise concerns to the environment.

“…A few reports of contact allergy to non-amine hardeners have been published in the case of dicyandiamide (Senff et al 1988), dodecenyl succinic anhydride (Göransson 1977), methylhexahydrophthalic anhydride (Kanerva et al 1997), hexavalent chromate, an accelerator additive (Handley and Burrows 1994;Bruze et al 1996) and polysulfides (Bruze et al 1996).…”

Epoxy resins are normally used in what is called an epoxy-resin system. This system consists of the epoxy resin and a hardener, and reactive diluent or other additives, such as fillers, modifiers, pigments and reinforcements. Epoxy ResinsEpoxy resins contain at least two cyclic three-membered ring structures containing oxygen, called epoxy groups, oxirane or epoxide groups, in their molecules. The term "epoxy resin" may refer to the resins in both the uncured thermoplastic and cured thermoset state. The uncured resins can be cross linked through the use of a variety of curing agents or hardeners to form cured plastics with insoluble three-dimensional structures.The reaction products of epichlorohydrin [CAS 106-89-8] and bisphenol A [CAS 80-05-7] resulted in the first commercial epoxy resins, which are generally mixtures of monomeric diglycidyl ether of bisphenol A (DGEBA), with a molecular weight (MW) of 340 Da, and oligomers with a higher MW (Fig. 1). Apart from the DGEBA and higher oligomers, side reactions result in the formation of low levels of impurities.DGEBA epoxy resins with a low average MW of 350-400 Da are liquids with a relatively high viscosity, and they contain up to and more than 90% monomeric DGEBA. Resins with a high average MW of over than 900 Da are solids (Muskopf and McCollister 1987), but may contain more than 15% DGEBA (Henriks-Eckerman and Laijoki 1986b).DGEBA epoxy resins account for about 75% of the epoxy resins used worldwide. Non-DGEBA epoxy resins possess special properties that have made them competitive with DGEBA resins for certain applications. A list of chemical names and CAS numbers of available epoxy resins is given in Table 1. The resin or mixture of resins chosen for a particular application depends on the desired balance of properties. For example, brominated epoxy resins are semisolids and resistant to ignition, and epoxy resins based on diglycidyl ether of bisphenol F (DGEBF) are less viscous and exhibit better chemical resistance than DGEBA epoxy resins (Ponten and Bruze 2001). Triglycidyl isocyanurate (TGIC) is one of the non-DGE-32 L. Kanerva et al. (eds.), Condensed Handbook of Occupational Dermatology
