Adjuvants & Formulations

Bimonthly newsletter for agchem specialists (former Adjuvant Newsletter)


March / April 2017

Pesticide formulations according to the ionic liquid approach
Ionic liquids attract increasing attention. These liquid salts are used as replacements of volatile organic solvents and as tunable materials. The ionic liquid approach is also used to improve the performance of active ingredients. Even more recent is the use of mixtures of ionic liquids as so-called designer solvents. Adjuvants & Formulations explored the state-of-the-art of ionic liquids as ‘green solvents’ in agrochemical formulations and as agrochemical active ingredients.

Patents in brief
Inventors at a specialty chemical company present a water conditioner that - although not mentioned - may act as penetration enhancer. Adjuvants & Formulations also reports about compositions that are suitable for formulating water-sensitive active ingredients, novel solid glyphosate and glufosinate formulations that are not hygroscopic, a rice-safe oxadiazon formulation, a photolysis-stable sulfentrazone formulation and an approach to transform water-insoluble actives into water-soluble compounds.
