Definitions
- the present invention relates to stable emulsions containing cinnamaldehyde and diallyl disulfide.
- the stable emulsions utilize Emulsogen ® EH and S rfonic ® CO 36 to form .a superior emulsion stability system.
- Emulsions generally refer to heterogeneous systems that comprise two immiscible liquids.
- emulsions provide formulation vehicles fo deliver)' of herbicides, insecticides, fungicides, bactericides, and fertilizers,
- Emulsions are inherently unstable, meaning that once they are formed, the immiscible liquids tend to revert or separate.
- Emulsifying agents such as surface- active agents, can be used to increase the stability of the emulsions.
- stable or “stability” means that the droplet particles of one liquid are uniformly distributed into another liquid and that this status is maintained for a desirable amount of time.
- Emulsions are especially useful in the field of agriculture wherein numerous lipophilic active ingredients must be dissolved and suspended into water prior to application to the plants.
- An oil-in- water emulsion (O/W emulsion) is an emulsion wherein liquid oil droplets are finely dispersed in water. Preparing stable O/W emulsions in very difficult and frequently involves extensive experimentation to determine formulations that provide stable concentrated products for end-use diluted emulsions.
- the emulsion system plays an essential role in providing stable emulsions, but identification of a proper system is complex and not easy to identify because of the required optimization of many different formulation characteristics, such as interfacial tension, viscosity, relative density, and temperature.
- Calsogen ⁇ EH (available from Clariant) is an emulsifier, specifically, an iso-Cl ' 2 alkyl benzene sulphonate calcium salt.
- Surfonic ® CO 36 (available from Huntsman., Inc.) is a surfactant and it contains poiyglycol esters of castor oil.
- Cinnamaldehyde is a naturally occurring organic compound that can be derived from the bark of trees of the genus Cinnamomu . Cinnamaldehyde is a viscous oil that has low solubility in water. Cinnamaldehyde does not present any known risk to humans or the environment and is considered to have a minimal safety risk. For this reason, it is not regulated by the Environmental Protection Agency ("EPA") because it is exempt from the Federal Insecticide, Fungicide, and Rodenticide Act (“FiFRA"). See 40 C.F.R. 152.25(f).
- EPA Environmental Protection Agency
- Cinnamaldehyde is known to have pesticidal activity.
- cinnamaldehyde- is effective against nematodes. See, for example, U.S. Patent No. 6,251,951 Bl.
- Diallyl. disulfide (4,5-dithia- 1 ,7-octadiene) is a naturally occurring organosulfi.tr compound that can be derived from garlic and plants of the genus Allium, Diallyl disulfide is an oil that has low solubility in water. Diallyl disulfide does not present any known risk to humans or the environment and is considered to have a minimal safety risk. For this reason, it is not regulated by the Environmental Protection Agency ("EPA") because it is exempt from the Federal Insecticide, Fungicide, and Rodenticide Act (“FIFRA"). See 40 C.F.R. ⁇ 152.25(f).
