ConsExpo is a computer program that enables the estimation and assessment of exposure to substances from consumer products such as paint, cleaning agents and personal care products. The model is developed by the National Institute for Public Health and the Environment.

ConsExpo is used within and outside Europe by governments, institutes and industries to assess the exposure to chemical substances from everyday consumer products. ConsExpo can be used for the safety assessment of industrial chemicals (REACH) and biocides.

Exposure via inhalation, via the skin or by oral intake can be assessed. Users choose the most appropriate scenario and fill in exposure parameters such as body weight and exposure duration. The program consists of both screening models and higher tier models for an exposure estimation.

Information about circumstances under which consumers are exposed to chemical substances from consumer products is available in so-called fact sheets. For several product categories so-called default parameter values are provided which can be used as a basis for the calculations in ConsExpo Web. These default values are also available in the database that is coupled to ConsExpo Web. By means of the fact sheets, the exposure assessment may be carried out in a transparent and standardised way.


In October 2016, ConsExpo Web was launched. ConsExpo Web contains the functionalities of ConsExpo 4.1 and the emission tool. The current version is ConsExpo Web version 1.0.5. The update of ConsExpo Web is realised by RIVMNational Institute for Public Health and the Environment in collaboration with the counterpart institutes ANSES (France), BfR (Germany), FOPH (Switzerland) and Health Canada. These institutes will continue to work on the further development of the instrument. In the future, ConsExpo Web can easily be expanded with new applications, such as for example an exposure assessment for short term exposure. Also, the content of the factsheets will be updated.

ConsExpo Web version 1.0.1 is released in July 2017. Exposure estimations made with this version of ConsExpo Web can be imported into Chesar through a ConsExpo Web export file. Chesar is the CHEmical Safety Assessment and Reporting tool of the European Chemicals Agency (ECHA). The development of this export functionality was financed by ECHA. Besides the introduction of a Chesar export functionality, the option to export graph data to excel was added and a few bugs were fixed.

ConsExpo Web version 1.0.2 is released in January 2018. As a new feature, the possibility to calculate a peak exposure (time weighted average for 15 min) for inhalation exposure is added. New also is that users can choose from a default list for the parameters body weight and inhalation rate. Furthermore, standard values from the updated Fact Sheet Cleaning Products (2018) are included in the fact sheet default database.
