The preservative 2-(thiocyanomethylthio) benzothiazole: a potential allergen in leather products.

Contact Dermatitis 2019 Apr 21. Epub 2019 Apr 21.

Department of Dermatology, Cliniques universitaires Saint-Luc, Brussels, Belgium.

Background: Allergic contact dermatitis (ACD) from leather is common, and several responsible allergens, such as tanning agents, glues, mercaptobenzothiazole- derivatives, dyes, but also antimicrobials and antifungals are involved.

Material And Methods: Three female patients were referred to the Departments of Dermatology in a Belgian university hospital following skin reactions caused by leather products (shoes, belt, and car seats). They were patch tested with the European Baseline Series and samples of suspected leather products, and additionally with 2-(thiocyanomethylthio)benzothiazole (TCMTB), an antifungal agent previously reported as a contact allergen in footwear.

Evaluation of in vitro testing strategies for hazard assessment of the skin sensitization potential of "real-life" mixtures: the case of henna-based hair coloring products containing p-phenylenediamine.

Contact Dermatitis 2019 Apr 21. Epub 2019 Apr 21.

Laboratory of Education and Research in In Vitro Toxicology - Tox In, Faculty of Pharmacy, Federal University of Goiás, Goiânia, GO, Brazil.

Background: Allergic contact dermatitis reported to henna-based hair coloring products (HPs) has been associated with adulteration of henna with p-phenylenediamine (PPD).

Objectives: To develop a testing approach based on in vitro techniques that address key events within the skin sensitization adverse outcome pathway to evaluate allergenic potential of HPs.

Methods: The following in vitro assays were used to test the sensitizing capacity of hair dye ingredients: micro-direct peptide reactivity assay (mDPRA); HaCaT keratinocytes-associated IL-18 assay; U937 cell line activation test (USENS)/IL-8 levels; blood monocyte-derived dendritic cell test; genomic allergen rapid detection (GARD skin).

Molecular docking predictions of fragrance binding to HLA molecules.

Contact Dermatitis 2019 Apr 7. Epub 2019 Apr 7.

Division of Cosmetics, Office of Cosmetics and Colors, Maryland.

Background: Over 4000 small chemicals have been identified as allergens capable of inducing skin sensitization.

Authors:
Anton C de Groot

Contact Dermatitis 2019 Mar 6. Epub 2019 Mar 6.

acdegroot publishing, Wapserveen, The Netherlands.

In this article, contact allergy to Myroxylon pereirae resin (MP) (balsam of Peru) is reviewed. The topics presented include the uses, the chemical composition, the frequency of sensitization, the relevance of positive reactions, the MP-containing products causing allergic contact dermatitis, co-reactivity with other fragrance and non-fragrance materials, the sensitizers, the usefulness of MP as a "marker" of fragrance allergy, and the effectiveness of and indications for "balsam-restrictive" diets. Sensitization to MP occurs in 4% to 8% of patients routinely tested for suspected contact dermatitis. Read More
