Abstract

Phospholipid concentrates from natural or synthetic phospholipids and physiologically acceptable organic solvents and further additives of the following composition: PA1 20-60 wght. % phospholipids PA1 0-23 wght. % glycerin PA1 5-62.5 wght. % organic solvent PA1 0-30 wght. % co-emulsifier PA1 0-35 wght. % dissolving intermediary PA1 0-15 wght. % water PA1 0-15 wght. % vegetable oil or neutral oil The phospholipids are a mixture of phosphatidyl choline, phosphatidyl ethanol amine, N-acetyl phosphatidyl ethanol amine, and other phosphatides, the concentrates perferably containing a mixture of 10-50 wght. % phosphatidyl choline, 10-30 wght. % phosphatidyl diethanol amine, 10-30 wght. % N-acylphosphatidyl ethanol amine, and 3-10 wght. % other phosphatides, in relation to the total quantity of phospholipids. The phospholipid concentrates are particularly suitable as auxiliary agents in the production and application of spray mixtures containing plant protectants.
