Three in vitro methods for the prediction of the skin sensitization hazard have been validated. However, predicting sensitizer potency is a key requirement for risk assessment. Here, we report a database of 312 chemicals tested in the KeratinoSens™

(E)-4-(ethoxymethylene)-2-phenyloxazol-5(4H)-one, commonly referred to as oxazolone, is the most potent skin sensitizer in published databases as determined with the murine local lymph node assay. It has been used very widely in immunological researc

A key step in the skin sensitization process is the formation of a covalent adduct between the skin sensitizer and endogenous proteins and/or peptides in the skin. A published peptide depletion assay was used to relate the in vitro reactivity of frag

Axillary odor is known since 50 years to be formed upon the action of Corynebacteria on odorless axilla secretions, but the nature of the bacterial enzymes involved in this process remained a mystery. We identified the known axilla odor determinant 3

Human axillary odor is known to be formed upon the action of Corynebacteria sp. on odorless axilla secretions. The known axilla odor determinant 3-methyl-2-hexenoic acid was identified in hydrolyzed axilla secretions along with a chemically related c

Bioaccumulation in aquatic species is a critical end point in the regulatory assessment of chemicals. Few measured fish bioconcentration factors (BCFs) are available for fragrance ingredients. Thus, predictive models are often used to estimate their

The defensive secretion of the ventral glands of both species, Hoplocampa testudinea and H. flava is mainly composed of acetogenins. Major compounds are (E)-2-octenal, (E,Z)- and (E,E)-2,4-decadienal and (E,Z,Z)-2,4,7-decatrienal that was identified

The betaine lipids diacylglycerylhydroxymethyltrimethyl-β-alanine (DGTA) and diacylglyceryltrimethylhomoserine (DGTS) can be identified by derivatization of their polar groups. Demethylation, deacylation and silylation of DGTS yields demethyl-deacyl

Summary The phosphoglyceride phosphatidyl- O -[ N (2-hydroxyethyl)glycine] (PHEG) has been isolated from Fucus serratus L. (Fucales, Phaeophyceae) and its structure determined by IR, NMR, MS and chemical data of the intact lipid (formerly called PX),

Skin sensitizers chemically modify skin proteins rendering them immunogenic. Sensitizing chemicals have been divided into applicability domains according to their suspected reaction mechanism. The widely accepted Schiff base applicability domain cove
