Zeolites are nanoporous, crystalline aluminosilicate materials comprised of a series of strictly uniform channels and cavities repeating along the tri-directional structure of the lattice. Over the last 30 years, researchers have increasingly recognized the desirable properties of these materials as hosts for photochemical reactions. This review will endeavor to draw attention to the properties of zeolite materials that make them appealing substrates for hosting guest molecules during photochemical reactions. An overview of some classical examples in zeolite host-guest photochemistry will be presented along with a brief description of a new use for zeolite materials as protective encapsulators.

“…Since 2001, cysteamine hydrochloride (HCl) has become a common ingredient of permanent waving products in Japan . Cases of allergic contact dermatitis caused by cysteamine HCl are still considered to be rare; however, it was frequently positive in a multicentre patch test study in which we participated …”

In addition to the Japanese baseline allergen series version 2008,11 we used cysteamine HCl 1% and 0.5% pet. (Table S1). We also included the participants' own perming solutions, as used by them at the salon, for open tests. RESULTSDetails of the 3 male and 4 female hairdressers, ranging in age from 22 to 73 years, are shown in Table S2. Regarding the cysteamine HCl patch tests, 5 patients showed positive reactions to both 1% and 0.5%. One patient showed a positive reaction to 1% alone, and the other patient, who had a positive reaction to 0.5%, had not been tested with 1% (Table 1). The results of the open test showed that, among 6 patients tested with the reducing agent of the permanent wave products, 5 showed erythema, partly oedema, or papules. Moreover, 6 patients also showed strong positive reactions to components of oxidative hair dye products and related substances. On the other hand, none of the 7 patients showed a positive reaction to ammonium thioglycolate. DISCUSSIONThe active chemicals used to create permanent waves are salts and esters of thioglycolic acid, L-cysteine, and cysteamine HCl. Contact dermatitis caused by cysteamine HCl is reportedly rare, and all cases were related to occupational use. 8,9 On the other hand, Tanita et al reported that 18.8% of 48 hairdressers showed positive patch test reactions to cysteamine 1% pet.in Japan. 12 In a Japanese multicentre study, 10 4.5% of patients (6/132) showed positive patch test reactions to cysteamine HCl 0.5% pet., and 12.6% (24/191) showed positive patch test reactions to cysteamine HCl 1% pet. Although 1% cysteamine HCl had exclusively been used for patch testing, the multicentre study showed that 1% cysteamine HCl may cause false-positive reactions, so a 0.5% concentration was regarded as being more suitable. 10

“…Sensibilisierungen gegen Ammoniumthioglykolat sind insgesamt selten, lassen sich aber häufiger bei Friseuren als bei ihren Kunden nachweisen und haben in den letzten Jahren etwas zugenommen [27,29]. Cysteaminhydrochlorid wurde erst kürzlich als neues Kontaktallergen in sauren Dauerwellemitteln identifiziert [16].…”

Hairdressers are exposed to a broad variety of substances known for their strong sensitizing and irritant capacities. Especially wet work and handling of hair-care products causes a high risk for occupational skin disease. Lately, due to new regulations regarding substances and techniques used as well as improved skin protection, the prevalence of occupational skin disease in hairdressers has significantly declined. It is of great importance to fulfill and extent these requirements to further minimize the risk of occupational skin disease in this profession.
