Abstract
Amido alkyl amine oxides, optionally blended with ether carboxylates, amphoteric surfactants, chelants, solvents, hydrotropes and/or wetting agents are used to prepare glyphosate solution concentrates.
Claims20
A herbicidal solution concentrate comprising from 30% by weight, to saturation of a water soluble glyphosate salt and from 8 to 20% by weight of surfactant comprising:
- 10 to 100% by weight based on the total weight of surfactant of an alkyl and/or alkenyl amido amine oxide of the formula:
- where R is a C6-20 alkyl or alkenyl group, m is 1 to 4, and p and q are independently 0 to 3;
- and from 0 to 90% by weight based on the total weight of surfactant of ether carboxylate.
A composition according to any foregoing claim containing at least 10% of an ether carboxylate which is a compound of the formula RO[CH2CH2O]mCH2CO2M where R is an alkyl, alkenyl or alkylphenol group having from 6 to 20 aliphatic carbon atoms m is 1 to 30 and M is potassium, ammonium or an amine.
A process for preparing a glyphosate solution concentrate comprising mixing water, a water-soluble glyphosate salt, an alkyl ether carboxylate, and an amido alkyl amine oxide.
