O-phenylphenol/alkoxylated amine wood protection compositions
A composition for protecting wood from decay, mildew and sapstain comprises o-phenylphenol in combination with an alkoxylated amine, wherein the weight ratio of alkoxylated amine to o-phenylphenol ranges from 1:1 to 10:1. Organic or inorganic acids may be added to enhance solubility of the alkoxylated amines.
1. A composition for protecting freshly cut Douglas fir from sapstain, consisting essentially of an aqueous emulsion containing 0.1 to 0.5 weight percent of o-phenylphenol and an alkoxylated amine in a weight ratio of 1:1 to 9:1 relative to the weight of o-phenylphenol.
2. The composition of claim 1 wherein the alkoxylated amine has the formula
wherein R 1 is a C 8-20 alkyl and R 2 is -[CH 2 CH(X)0] b H and a and b are integers ranging from 1 to 20, and X is selected from the group consisting of hydrogen, methyl, ethyl and phenyl.
3. The composition of claim 2 wherein R 2 is
n is an integer from 1 to 4, each a,b,c are integers ranging from 1 to 20, and X is selected from the group consisting of hydrogen, methyl, ethyl and phenyl.
4. The composition of claim 2 wherein R 1 is cocoalkyl.
5. The composition of claim 2 wherein R 1 is tallowalkyl.
6. The composition of claim 5 wherein R 2 is N,N 1 ,N 1 -tris-(2-hydroxyethyl)-N-tatlowalkyl-1,3-diaminopropane.
7. The composition of claim 1 further comprising a monocarboxcylic acid.
