Some phthalates are classified in the hazard class reproductive toxicity category 1B and they are subject to authorisation or they have restrictions according to the REACH Regulation. The presence of six phthalates in detergents and cleaning products was determined using two different methods. The phthalates determined were dimethyl phthalate (DMP), diethyl phthalate (DEP), din-butyl phthalate (DBP), bis (2-ethylhexyl) phthalate (DEHP), benzyl butyl phthalate (BBP) and di-n-octyl phthalate (DOP). Method 1 consisted of gas chromatography and mass spectrometry, and method 2 consisted of reverse-phase liquid chromatography and mass spectrometry. Using method 1 phthalates were determined in 14 out of the 27 samples, and 4 out of the 6 analysed
