Dispersant compositions for treating oil slicks on cold water

The compositions comprise a solution of surface-active agents in a ternary mixture of water, hydrocarbon solvent and glycol ether. The surface-active agents are a mixture of wetting agent and emulsifying agents, the latter consisting of two blends of sorbitan derivatives, blend A having an HLB of 8....

Zusammenfassung:The compositions comprise a solution of surface-active agents in a ternary mixture of water, hydrocarbon solvent and glycol ether. The surface-active agents are a mixture of wetting agent and emulsifying agents, the latter consisting of two blends of sorbitan derivatives, blend A having an HLB of 8.5 - 9.5 and blend B having an HLB of 8 - 10, the weight ratio A:B being of from 1:2 to 4:1.
