Therefore, it is necessary to explore how to give full play to the important roles of standardization in the development of circular economy, how to make use of standardization to accelerate the promotion and application of advanced technology for circular economy and to develop the circular economy with the help of standardization.展开更多
This paper introduced the development of Technical Safety Standards for Cosmetics(TSSC). It explained changes in TSSC in detail and put forward related suggestions for implementation.

As the investment and implementation actions improve and the social economic criteria are delimited by regulatory frameworks, it is extremely necessary to monitor previous performances and further prospects, regarding projects, it is necessary to measure the extent of which efforts have been meeting regulatory requirements and aiming to contribute with sustainable development. In this context, the use of indicators has been a major management tool.展开更多
