The sum parameter of organic halogens is determined in cosmetics. Here, the samples are extracted by steam distillation or extraction with a solvent to analyse the organic halogen content. The main causes for a positive finding in cosmetics are preservatives from the class of organic halogens. The sum parameters are characterized precisely by the fact that all the substances belonging to the group of organic halogen compounds which are soluble in hot water can be determined. There is no danger that individual substances in the class can be overlooked.
