Integrating new habits and practices data and homecare products into the Creme RIFM aggregate exposure model

The Research Institute for Fragrance Materials (RIFM) and Creme Global, in collaboration with fragrance and consumer products industries, have developed an aggregate exposure model for fragrance ingredients in cosmetics, personal care, and air care products. At the core of this model is product concentration data provided by manufacturers (fragrance suppliers and consumer product companies) and habits and practices survey data collected by Kantar Worldpanel. The model is dynamic and flexible, allowing for updates based on new data and evolving science, with several updates released since its inception. In the most recent phase of model development (Phase III), the 2007-2008 Kantar Worldpanel survey data have been updated, replacing them with habits and practices survey data collected in 2014 and 2015 for the same products acquired during the Phase I and Phase II updates to the model. In addition to replacing existing data, the new survey includes data on additional products, countries, and expanded age groups. The list of products in the model was also expanded to include several household care products. This manuscript summarizes the new data and presents comparisons between the exposure factor inputs for the new and old models.
