The system works by pre-dosing chemical product into individual water-soluble sachets using a dedicated packaging machine, so that end users add the entire sealed unit directly into a process (such as a wash or treatment bath) without opening the packaging or handling the raw chemical directly, and without needing to measure a dose themselves. The biodegradable, bio-based film dissolves fully once immersed in hot water, leaving no packaging waste to dispose of and eliminating the risk of operators being exposed to concentrated product during transfer, a safety benefit alongside the environmental one.

Cefic frames the innovation as an example of how industrial performance, sustainability and user safety can converge in a single, relatively modest engineering solution, one achievable by a specialised SME rather than requiring the capital scale of a multinational producer. For smaller chemical formulators facing similar packaging waste and dosing accuracy challenges, TCN's approach illustrates that meaningful Responsible Care innovation does not necessarily require large R&D budgets, but rather a willingness to rethink a routine operational step that is often taken for granted.
