• Objective Trichlorethylene, a substance of very high concern (SVHC), has been widely used as a degreasing or cleaning material for metal parts and surfaces. However, it is being replaced by detergents blended with trans-1,2-dichlorethylene (tDCE) and other compounds owing to the regulation of SVHC use in various countries. However, tDCE is difficult to use in some processes because of its low flash point. Therefore, it is necessary to develop a new bio-friendly detergent additive that can reduce the flammability of the synthesized detergents. Methods The synthesis of heptafluoro-3-(2,2,2-trifluoroethoxy)propane (HFP), a new substance, was confirmed by nuclear magnetic resonance and Fourier transform infrared (FT-IR) spectroscopy, and the effect of detergents containing HFP was confirmed through the dyne pen, contact angle, and FT-IR. Results With the addition of HFP, the flash point of the detergent increased, the detergent containing HFP did not exhibit metal corrosion, and the cleaning effect was maintained. Conclusion The developed HFP is expected to contribute to the development of bio-friendly detergents because it has low biotoxicity and can be used in various industrial cleaning processes. This is because detergents containing HFP exhibit low corrosiveness and excellent cleaning effects.
