ABSTRACT:
FIELD OF THE INVENTION
The invention relates to solutions, solid and liquid dispersions, and emulsions of biologically active organic compounds, in particular, herbicides and safeners, insecticides, fungicides, acaricides, nematicides, pheromones and repellents, and more particularly, insecticidal active substances.
BACKGROUND OF THE INVENTION
Formulations of herbicidal, fungicidal or insecticidal active substances typically employ adjuvants, such as solvents, inert fillers, such as chalk, kaolin or silica, in particular surface-active substances. These formulations enable the preparations to wet substrates well and/or allow easy dispersion in water when they are used. In the case of the water-dispersible granules, adjuvants allow rapid disintegration after introduction into water.
There are processing and application problems associated with the preparation of formulated bio-active compounds, especially those having a relatively low melting point of 100° C. and below. The prior art suggests a variety of solvents used in conjunction with these substances. Suitable suggested solvents are the high-boiling alkylbenzenes and xylenes, 1- or 2-methylnaphthalene, dimethylnaphthalenes, and other polynuclear aromatic compounds. Other water-immiscible solvents suggested include paraffin oils, vegetable oils, alicyclic compounds, alkanols, such as cyclohexanol and isooctyl alcohol, ethers, ketones, such as cyclohexanone, 4-methylcyclohexanone and isophorone, and esters, such as ethyl benzoate and tri-n-butyl phosphate. Many of these solvents have a low flash point temperature and are bioaccumulative, presenting hazards and toxicity problems.
Surprisingly, a class of organic solvent has been found to be highly effective for dissolving organic bio- active compounds, which has generally a high flash point, and is not bioaccumulative. The invention provides a solvent for formulated bio-active compounds that bio-degrades into non-hazardous, and is non-bioaccumulative.
SUMMARY OF THE INVENTION
The invention therefore relates to bio-active preparations, as solutions, solid or liquid dispersions, suspensions and emulsions comprising a bio-active compound and a water soluble or oil soluble acetal. Particular exemplary embodiments include emulsifiable concentrates (EC), water dispersible granules (WG), and suspoemulsions.
An further object of the present invention is to provide oil-in-water (O/W) emulsions of bio-active compounds and acetal in the oil phase, in stable colloidal dispersion in water.
Another object of the present invention is to provide formulated bio-active compounds characterized as having low volatility, high flash point and which are toxicologically safe.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Broadly, the bio-actives in solution, dispersion, emulsion or adsorption onto solids, together with acetals according to the present invention are active organic compounds, in particular, herbicides and safeners, insecticides, fungicides, acaricides, nematicides, pheromones and repellents.
