Faced with the EU's strict restrictions on D4, domestic cosmetics companies are also taking active actions. On the one hand, they strengthen communication and cooperation with raw material suppliers to jointly explore alternatives to D4; on the other hand, they strengthen product safety assessment and quality testing to ensure that products comply with relevant domestic and international regulations. In addition, some companies have also launched a series of environmentally friendly cosmetics that do not contain D4 through technological innovation and product research and development to meet consumers' demands for environmental protection and health. These measures not only help to enhance the international competitiveness of enterprises, but also make positive contributions to promoting the green development of the cosmetics industry.
