With the increasing global awareness of environmental protection and the promotion of regulatory policies, the development of environmentally friendly defoamers has become an inevitable trend in the industry. In the future, environmentally friendly defoamers will pay more attention to the greenness of raw materials, using renewable resources, bio based materials, or materials with low toxicity and low volatile organic compound (VOC) content to reduce environmental pollution. While maintaining excellent defoaming performance, environmentally friendly defoamers will develop towards high efficiency and multifunctionality, such as possessing antibacterial and antioxidant functions, to meet the diverse needs of different industries for defoamers. Combining Industry 4.0 technology, the production of environmentally friendly defoamers will be intelligent, improving production efficiency and product quality. At the same time, we provide customized services and develop suitable defoamer products based on customers' specific needs.

The introduction of green raw materials and advanced technologies may increase production costs. How to control costs while maintaining environmental performance is a major challenge for the development of environmentally friendly defoamers. Environmentally friendly defoamers need to find a balance between performance, stability, and environmental friendliness, and breaking through technological bottlenecks requires time and research and development investment. Traditional defoamers have a certain foundation and customer base in the market, while environmentally friendly defoamers require time and effort to improve market acceptance.

In the future, what we need to do is to increase investment in technological innovation and research and development, and develop environmentally friendly defoamers with excellent performance and controllable costs. At the same time, the government should introduce relevant policies to encourage and support the research and application of environmentally friendly defoamers, such as providing tax incentives, financial support, etc. At the same time, strengthen market education and promotion work to enhance customers' awareness and acceptance of environmentally friendly defoamers.

The development of environmentally friendly defoamers in the future will show a trend towards greening, efficiency, intelligence, and customization. Faced with challenges such as cost control, technological bottlenecks, and market acceptance, it is necessary for the government, enterprises, and research institutions to work together to promote the widespread application and sustainable development of environmentally friendly defoamers through strategies such as technological innovation, policy guidance, and market promotion.
