Definitions
- the present invention pertains to synergistic compositions suitable for use in the treatment and preservation of wood and wood products.
- the antimicrobial compositions of this invention include wood preservative compositions comprising a polymeric betaine and an iodopropynyl compound. These combinations are especially useful in protecting wood and wood products from spoilage resulting from the growth of microorganisms, especially microorganisms that produce mold and sapstain.
- antimicrobial materials included halogenated compounds, organometallic compounds, quaternary ammonium compounds, phenolics, metallic salts, heterocyclic amines, formaldehyde adducts, organosulfur compounds, and the like.
- No single organic antimicrobial compound is able to provide protection against all microorganisms and is suitable for all applications.
- other limitations may restrict the usefulness of certain antimicrobials. For example the stability, physical properties, toxicological profile, regulatory considerations, economic considerations or environmental concerns may render a particular ingredient unsuitable for a particular use. There is a need, therefore, to constantly develop new combinations that will offer broad spectrum protection from a variety of needs.
- a judicious choice of combinations may provide a way to maximize benefits while at the same time minimize problems.
- a combination wherein the antimicrobial activity is enhanced while the less desirable properties are suppressed or reduced can provide a superior product.
- the task is to find such combinations that will provide protection against a wide variety of problem microorganisms, will not adversely affect the product to be protected, will maintain its integrity for an extended period of time, and will not have any strong adverse effects on health or the environment.
- the present invention is directed to certain synergistic preservative compositions comprising a polymeric betaine and an iodopropynyl compound.
- the present invention is also directed to methods for controlling mold and/or sapstain on wood or wood products by application of an effective amount of such compositions to the wood or wood product substrate.
- iodopropynyl compounds such as 3-iodo-2- propynyl butyl carbamate (IPBC) are combined with polymeric betaines such as didecyl bis(hydroxyethyl) ammonium borate (DPAB), they form wood preservative compositions that are surprisingly more effective against microorganisms that produce mold and/or sapstain on wood or wood products than either single component alone.
- polymeric betaines and iodopropynyl compounds complement one another in a way that could not be anticipated.
- the polymeric betaines and iodopropynl compound show synergistic activity. This unexpected synergistic activity offers a number of advantages in the preservation of wood and wood products.
- This invention relates to the synergistic wood preservative composition
- polymeric betaine or more precisely didecyl bis(hydroxyethyl) ammonium borate (DPAB), and 3-iodo-2-propynyl butyl carbamate having the properties of providing effective and broader control of microorganisms that produce mold and sapstain.
- DPAB didecyl bis(hydroxyethyl) ammonium borate
- 3-iodo-2-propynyl butyl carbamate having the properties of providing effective and broader control of microorganisms that produce mold and sapstain.
- Suitable polymeric betaines are described in, for example, U.S. Patent No. 5,304,237, the entire contents of which are incorporated herein by reference.
- the structural formula of DPAB is:
- the antisapstain compositions of the invention can be prepared as solutions or emulsions by conventional means by using water or organic liquids as a solvent.
- a preferred form
- the quantity and ratio of polymeric betaine and IPBC will depend upon the specific application.
- the wood preservative composition will contain from about 1 to 100 parts by weight polymeric betaine per about 1 to 100 parts by weight IPBC. More preferably, the composition will contain about 1 to 90, 1 to 80, 1 to 70, 1 to 60, 1 to 50, or 1 to 40 parts by weight of polymeric betaine per 1 to 90, 1 to 80, 1 to 70, 1 to 60, 1 to 50, or 1 to 40 parts by weight of IPBC.
- a preferred weight ratio of polymeric betaine to IPBC is from about 30:1 to about 1:30, more preferably 20: 1 to 1:20, even more preferably 10:1 to 1: 10.
- a particularly preferred ratio of polymeric betaine to IPBC is from 5: 1 to 10: 1 parts by weight, i.e., about 5 to 10 parts by weight polymeric betaine per part by weight IPBC.
- Other preferred ratios of polymeric betaine to IPBC include 1: 1, 2: 1 to 1:2, 3:2 to 2:3, 3:1 to 1:3, 4: 1 to 1:4, 4:3 to 3:4, 5: 1 to 1:5, 5:2 to 2:5, 5:3 to 3:5, 5:4 to 4:5, 6: 1 to 1:6, 6:5 to 5:6, 7: 1 to 1:7, 7:2 to 2:7, 7:3 to 3:7, 7:4 to 4:7, 7:5 to 5:7, 7:6 to 6:7, 8:1 to 1:8, 8:3 to 3:8, 8:5 to 5:8, 8:7 to 7:8, 9: 1 to 1:9, 9:2 to 2:9, 9:4 to 4:9, 9:5 to 5:9, 9:7 to 7
- the preservative composition may be advantageous to supply the preservative composition in concentrated form with about 15, 20, 25, 30, 35, 40, or 45 percent by weight of solvent to about 50, 55, 60, 65, 70, 75, or 80 percent by weight solvent.
- the composition may comprise more than 80 percent by weight of solvents, for example from 80 to 99.9, 85 to 99.9, 90 to 99.9, 90.5 to 99.9, 91 to 99.9, 91.5 to 99.9, 92 to 99.9, 92.5 to 99, 93 to 99.9, or 95 to 99.9 percent by weight of solvent.
- Typical solvents include water and/or organic solvents, including aromatic organic solvents, polar and non-polar organic solvents, and aliphatic organic solvents.
- the concentrate is generally diluted about 10 to 200 times to working solution strength by the addition of water (or another solvent).
- the diluted solution or emulsion can be applied to wood by conventional treating methods such as immersion, brush, spray, flooding, or pressure.
- antimicrobial mixtures provide a high level of activity over a prolonged period, providing the strengths of the individual ingredients while minimizing the weaknesses of each. It is this type of complimentary activity that allows one to use less biocide in combination to achieve a desired effect at levels that cannot be achieved with any of the individual ingredients.
- halopropynyl compounds that can be used in accordance with the present invention, for the most part, are well known and can be generally identified by the following structure:
- YC C-CH 2 X
- X can be (1) oxygen that is part of an organic functional group; (2) nitrogen that is part of an organic functional group; (3) sulfur that is part of an organic functional group; or (4) carbon that is part of an organic functional group.
- the functional group of which oxygen is a part is preferably an ether, an ester, or a carbamate group.
- the functional group of which nitrogen is a part is preferably an amine, an amide, or a carbamate group.
- the functional group of which sulfur is a part is preferably a thiol, a thiane, a sulfone, or a sulfoxide group.
