One hundred twin pairs patch tested with primary irritants*

Abstract
The cutaneous sensitivity to benzalkonium chloride, sodium lauryl sulphate and potash soap was determined in 54 monozygotic and 46 dizygotic twin pairs. Comparing the intra-pair reaction strength a higher degree of concordance was found among monozygotic than among dizygotic twins, and even more so when monozygotic twins were compared with matched controls.
