Jacob P Thyssen et al.
Contact dermatitis, 62(2), 102-108 (2010-02-09)
Most cosmetics and industrial products contain preservatives. Preservative allergy is common and, historically, changing contact allergy epidemics caused by preservatives have been observed. In 1997, Alan Dillarstone predicted a stable development of preservative allergy following mandatory ingredient labelling on cosmetic
National Toxicology Program technical report series, (555)(555), 1-171 (2010-08-21)
1,2-Dibromo-2,4-dicyanobutane is used in cosmetics and other household products. 1,2-Dibromo-2,4-dicyanobutane was nominated for study by the National Institute of Environmental Health Sciences because of its widespread use as a component of numerous over-the-counter health care products. Male and female F344/N

It is not known if reduced elicitation thresholds are evident among polysensitized individuals when using allergens to which the patients are already sensitized. Reduced elicitation thresholds may be an expression of increased reactivity in this patient group. To examine and

A simple and rapid gas chromatography (GC) method with mass spectrometry (MS) detection has been developed for the determination of methyldibromo glutaronitrile (MDBGN) in cosmetic products. The presence of this preservative in commercial cosmetic samples is prohibited since 2007 because

Contact dermatitis, 59(2), 90-95 (2008-09-02)
A key consideration when undertaking risk assessments should be the potential for synergy between contact allergens. Previously, this concept has only been investigated during elicitation in contact allergic individuals. To determine whether there exists evidence for synergy between contact allergens

Methyldibromoglutaronitrile (MDBGN) is a preservative, which was approved for use in cosmetics in the mid-1980s. The incidence of allergy to MDBGN rose during the 1990s, but is now decreasing due to regulatory intervention. Experimental studies with other allergens have shown

We inform about a case of occupational allergic contact dermatitis (OACD) to methyldibromoglutaronitrile (MDBGN) in industrial hand degreasing moist toilet paper. To our knowledge, this is the first published case of OACD to MDBGN in industrial hand degreasing toilet papers.

Euxyl K400 is a widely used preservative in cosmetics, topical drugs, cutting fluids, etc. This antimicrobial product has two active components: methyldibromoglutaronitrile (MDGN), also known as 1,2-dibromo-2,4-dicyanobutane, and 2-phenoxyethanol, in a proportion of 1 to 4. The aim of this

To evaluate chemicals (e.g. lipophilic chemicals, pre/pro-haptens) that are difficult to correctly evaluate using in vitro skin sensitization tests (e.g. DPRA, KeratinoSens or h-CLAT), we developed a novel in vitro test termed "Epidermal Sensitization Assay: EpiSensA" that uses reconstructed human

Methyldibromoglutaronitrile/phenoxyethanol (Euxyl K 400) is a preservative found in both personal care products and industrial sources. Although Euxyl K 400 initially appeared to have low sensitizing potential, increased prevalence of contact allergy to Euxyl K 400 led to regulatory intervention.
Louise Arup Fischer et al.
Contact dermatitis, 61(4), 201-208 (2009-10-15)
Allergic contact dermatitis is common and can be prevented. The relationship between thresholds for patch tests and the repeated open application test (ROAT) is unclear. It would be desirable if patch test and ROAT data from already sensitized individuals could

in Europe, methyldibromoglutaronitrile (MDGN) was banned because of excessive rates of contact allergy. However, it is unclear whether the concentrations used for testing MDGN are optimal, as different groups have used varying concentrations with quite different rates of positive reactions.

Delayed-type hypersensitivity represents a significant clinical and public health challenge. Patients undergoing patch testing may exhibit positive reactions to more than one allergen. It is recognized that reactions to specific pairs of allergens are associated, reflecting a combination of exposure

In order to map the frequency of contact hypersensitivity (CH) to epoxy resin, methyldibromoglutaronitrile (MDBGN), tixocortol pivalate (TP) and budesonide patch tests were carried out. The tests were performed in 1448 patients. Most patients belong to the allergic and irritative

Occupational contact dermatitis is common in healthcare workers. Although irritant contact dermatitis resulting from wet work is the most frequently reported cause, healthcare workers also constitute high-risk group for the development of allergic contact dermatitis and contact urticaria.

While the use of methyldibromo glutaronitrile (MDBGN) in leave-on products is clearly associated with high sensitization or elicitation risk, such a clear-cut relation could be questioned with regard to rinse-off products. The objective of this study was to find a

Although genetic factors probably account for differences in susceptibility to contact allergy, they have not yet been identified, partly due to an insufficient understanding of 'susceptibility'. Regarding polysensitization (PS) as a sign of increased susceptibility, we studied the relationship between
