PHOSPHOLIPID CONCENTRATES AND THEIR USE AS AN AUXILIARY SUBSTANCE FOR THE PRODUCTION OF SPRAYERS CONTAINING PLANT PROTECTION PRODUCTS.

摘要

Phospholipid concentrates from natural or synthetic phospholipids and physiologically acceptable organic solvents and further additives of the following composition: 20-60 wght. % phospholipids 0-23 wght. % glycerin 5-62.5 wght. % organic solvent 0-30 wght. % co-emulsifier 0-35 wght. % dissolving intermediary 0-15 wght. % water 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.
