The EU is expected to launch a consumer APP to strengthen the improvement of the SVHC phase-out rate. Recently, the EU REACH authorities, NGOs and academic units have worked together to promote the AskREACH APP project, aiming to enhance consumers' knowledge and understanding of substances of very high concern (SVHC) in products. What are the negative risks of these SVHCs to the human body and the environment, and help consumers identify the SVHCs contained in products so that consumers can make informed purchasing decisions. This project was initiated by the German Environmental Protection Agency (UBA) and has brought together more than 20 project partners from 13 EU member states to assist in the development and construction of this APP, which is expected to be launched in the spring of 2019. Another purpose of the plan is to encourage manufacturers to replace SVHC in their products. Through the transparent information of the APP, it reminds retailers, manufacturers, importers and their supply chain manufacturers that they must comply with the requirements of REACH regulations, while strengthening the supply chain. information communication. The ultimate goal of this project is, of course, to increase consumer awareness of SVHC in products, leading to the replacement of all SVHC in products marketed in the EU with safer chemicals. For this project to be successful, it will require an EU central IT system that includes the following three elements: – An information center where companies can upload SVHC data in products; – In addition to providing consumers with multiple language options, a smart APP, this APP must also be used at the sales location through big data technology
