Systemic exposure was measured in humans after hair dyeing with oxidative hair dyes containing 2.0% (A) or 1.0% (B) [14C]-p-phenylenediamine (PPD). Hair was dyed, rinsed, dried, clipped and shaved; blood and urine samples were collected for 48 hours after application. [14C] was measured in all materials, rinsing water, hair, plasma, urine and...

We monitored the exposure of hairdressers to oxidative hair dyes for 6 working days under controlled conditions. Eighteen professional hairdressers (3/day) coloured hairdresser's training heads bearing natural human hair (hair length: approximately 30 cm) for 6 h/working day with a dark-shade oxidative hair dye containing 2% [14C]-para...

Background and objective: The dopamine agonist rotigotine has been formulated in a silicone-based transdermal system for once-daily administration. The objective of the present study was to characterise the mass balance of rotigotine in humans after administration of a single transdermal patch containing radiolabelled [14C]rotigotine and to...

Background: Vitamin A is widely used in cosmetic preparations. Given that oral Vitamin A and its metabolites present a potential reproductive risk, the present study investigated the effect of topical Vitamin A on human endogenous plasma levels of Vitamin A and its metabolites. Methods: Two groups of 14 female volunteers of child-bearing age...

The health risks of inhalation exposure to volatile organic solvents may not only depend on the total external dose, but also on the pattern of exposure. It has been suggested that exposure to regularly occurring peak concentrations may have a stronger impact on the brain than constant exposure at the same average level. Recent animal...

We investigated the absorption of a commercial [14C]-PPD- containing oxidative dark-shade hair dye in human volunteers as well as in vitro using human or pig ear skin. The hair of eight male volunteers was cut to a standard length, dyed, washed, dried, clipped and collected. Hair, washing water, materials used in the study and a 24-h scalp wash...

In the organism of mammals, important detoxification pathways of arylamines are catalysed by N-acetyltransferase 2 (NAT2). A recent case-control epidemiology study suggested that human NAT2 slow acetylators exposed to oxidative hair dyes may be at greater risk to develop bladder cancer. We therefore profiled urinary [14C]-metabolites and NAT2...

Objectives: To assess excretion kinetics of free and total (free + conjugated) 2-butoxyacetic acid (BAA) following dermal and inhalation exposure to butoxyethanol (BE). Methods: Six male volunteers were derma lly exposed for 4 h to a 50% aqueous solution of BE on an area of 40 cm2 of the volar forearm. Six other male volunteers were exposed by...

The potential human health risk of UV filters depends on their toxicity and the human systemic exposure which is a function of the extent of percutaneous absorption of the topically applied substance into the human organism. Using a 'mass balance' approach, a study was designed to investigate the systemically absorbed dose of [14C]-Mexoryl SX®...

Malathion was applied to roses in three Finnish greenhouses by hand held lance sprayers. The potential dermal exposure of applicators to this insecticide was measured. Total urine production of each applicator was also collected up to 24 h post application. In the urine samples the specific metabolite of malathion, malathion monocarboxylic acid ...

The validity of in vitro and in vivo methods for the prediction of percutaneous penetration in humans was assessed using the fungicide ortho-phenylphenol (OPP) (log Po/w 3.28, MW 170.8, solubility in water 0.7 g/L). In vivo studies were performed in rats and human volunteers, applying the test compound to the dorsal skin and the volar aspect of...

In vitro and in vivo skin absorption of the pesticide propoxur (2-isopropoxyphenyl N-methyl carbamate, commercially Baygon(TM) and Unden(TM); log Po/w 1.56, MW 209.2) was investigated. In vivo studies were performed in rats and human volunteers, applying the test compound to the dorsal skin and the volar aspect of the forearm, respectively. In...
