Using dispersants is known to be an effective solution to accelerate the natural dispersion and being an appropriate oil spill response strategy. By breaking up large oil chunks into small droplets, dispersants are generally intended to help reducing further oil exposures and slicks. Collecting property data of circulating crude oil in South Korea and understanding the interaction between crude oils and dispersions need to be preceded for the effective dispersant use. This paper provides an property analysis of three selected oils which have the same composition of spilt oils from the Herbei Spirit Incident and conducts an emulsification and toxicity experiment with selected domestic and foreign dispersants. Results will present a direction of future domestic dispersants' development which aimed at eco-friendly and safety.
