limonene; and
water; and
wherein copper is present in an amount of about 5% to about 10% by weight of the composition; and
wherein said composition is homogenous and does not exhibit phase separation for at least 30 days when maintained at 25° C. in a stationary condition; and
wherein the one or more alpha olefin sulfonate surfactants are present in an amount of about 0.1 to about 15% by weight of the composition.
2. The composition of claim 1 , wherein:
said one or more alpha olefin sulfonate surfactants comprise a linear carbon chain in the range of about 4 to about 20 carbon atoms.
3. The composition of claim 1 , wherein:
the one or more alpha olefin sulfonate surfactants are present in an amount of about 0.1 to about 10% by weight of the composition.
4. The composition of claim 1 , wherein:
the one or more alpha olefin sulfonate surfactants are present in an amount of about 0.1 to about 5% by weight of the composition.
5. The composition of claim 1 , wherein:
copper is present in an amount of about 7% to about 10% by weight of the composition.
6. The composition of claim 1 , wherein:
said one or more alpha olefin sulfonate surfactants comprise a linear carbon chain in the range of about 4 to about 20 carbon atoms.
7. The composition of claim 1 , wherein:
said one or more alpha olefin sulfonate surfactants comprise a linear carbon chain in the range of about 8 to about 20 carbon atoms.
8. The composition of claim 1 , wherein:
said one or more alpha olefin sulfonate surfactants comprise a linear carbon chain in the range of about 12 to about 20 carbon atoms.
9. The composition of claim 1 , wherein:
said one or more alpha olefin sulfonate surfactants comprise a linear carbon chain in the range of about 14 to about 20 carbon atoms.
10. The composition of claim 1 , wherein:
said one or more alpha olefin sulfonate surfactants comprise a linear carbon chain in the range of about 14 to about 16 carbon atoms.
11. A composition, comprising:
copper complexed with one or more alkanolamines;
one or more alpha olefin sulfonate surfactants;
one or more additional surfactants selected from the group consisting of anionic, nonionic, or cationic surfactants;
water;
wherein said composition is homogenous and does not exhibit phase separation for at least 30 days when maintained at 25° C. in a stationary condition; and
wherein the one or more alpha olefin sulfonate surfactants are present in an amount of about 0.1 to about 15% by weight of the composition.
12. The composition of claim 11 , wherein:
the one or more additional surfactants include a hydroxyalkane sulfonate surfactant.
13. The composition of claim 11 , wherein the copper complexed with one or more alkanolamines constitutes at least about 5% by weight of the composition.
14. The composition of claim 13 , wherein the copper complexed with one or more alkanolamines constitutes no more than about 50% by weight of the composition.
15. The composition of claim 14 , wherein the copper complexed with one or more alkanolamines constitutes about 10% to about 40% by weight of the composition.
16. The composition of claim 11 , also comprising d-limonene, 1-limonene, or a combination thereof.
17. A method of controlling the growth of algae comprising the step of adding to a body of water an algaecidally effective amount of the composition of claim 1 .
18. The method of claim 17 , wherein the algae to be treated include one or more of Hydrodictyon spp., Pithophora spp., Lyngbya spp., Oscillatoria spp., Nitella spp., Chara spp., Phormidium spp., Microcystis spp., Anabaena spp., Aphanizomenon spp., Nodularia spp.
19. A method for treating a surface or environment comprising applying to the surface or environment (i) a composition of claim 1 , or (ii) a composition prepared by combining a composition of claim 1 with another substance.
20. The method of claim 19 , wherein said another substance is an aqueous liquid medium.
21. The method of claim 19 , which is a method for algaecidally treating an aquatic environment.
