Hydroxycitronellal, an important ingredient in fragrances, was studied for its sensitizing potential in human skin. Fifteen human maximization tests were conducted with hydroxycitronellal obtained from four different sources at induction concentrations from 5 to 12%. No reactions were induced at

Household and cleaning products often contain both allergens and irritants. The aim of this double-blinded, randomized, paired study was to determine whether patch testing with an allergen (hydroxycitronellal) combined with an irritant [sodium lauryl sulfate (SLS)] cause a stronger patch

Food and chemical toxicology : an international journal published for the British Industrial Biological Research Association, 42(11), 1719-1725 (2004-09-08)
The clinical relevance of patch test reactions is often difficult to determine. Use tests have been developed to further evaluate the significance of patch test results. We review studies that have defined correlations between the threshold concentrations at patch testing

Contact dermatitis, 48(6), 324-330 (2003-10-09)
Recently, we showed that 10 x 2% of consecutively patch-tested hand eczema patients had a positive patch test to a selection of fragrances containing fragrances relevant to hand exposure. In this study, we used repeated skin exposure to a patch
