What does this research mean for the field?

Sensitization to benzisothiazolinone (BIT) is increasing in dermatitis patients, and consumer products with prolonged skin contact contain BIT concentrations several orders of magnitude higher than CMIT/MIT. Novelty: ClaimNovelty.CONFIRMATORY. Consensus alignment: ConsensusAlignment.SUPPORTS_CONSENSUS.

What question did this study set out to answer?

The research aims to develop a method for analysing isothiazolinones due to rising sensitisation rates.

Key Points

The research aims to develop a method for analysing isothiazolinones due to rising sensitisation rates.
Analysis of consumer products containing isothiazolinones.
Comparison of concentrations of benzisothiazolinone and CMIT/MIT.
Evaluation in dermatitis patients in western Sweden.
Confirmed increasing sensitisation rates to benzisothiazolinone in dermatitis patients.
Product analysis revealed BIT concentrations significantly higher than CMIT/MIT.

Abstract

Results confirm previous reports indicating that sensitisation to BIT is increasing in dermatitis patients in western Sweden. Analysis of products showed that concentrations of BIT can be several orders of magnitude higher than those of CMIT/MIT in products to which skin contact can be frequent and long lasting.
