Claims (17)

1. A composition, comprising:

a. succinic acid, glutaric acid, adipic acid, pimelic acid, and azelaic acid, or the salts or esters thereof;

b. at least one of oxalic acid, suberic acid, sebacic acid, undecanedioic acid, dodecanedioic acid, tridecanedioic acid, tetradecanedioic acid, pentadecanedioic acid, 2-octenedioic acid, 2-nonenedioic acid, 2-decenedioic acid, and 2-undecenedioic acid, or the salts or esters thereof; and

c. at least one of 2-nitro-suberic acid, 2-nitro-azelaic acid, 2-nitro-sebacic acid, 2-nitro-undecanedioic acid, 2-nitro-dodecanedioic acid, 2-nitro-brassylic acid, 2-nitro-tetradecanedioic acid, 2-nitro-pentadecanedioic acid, 2-nitro-hexadecanedioic acid, 2-nitro-heptadecanedioic acid, 2-nitro-octadecanedioic acid, 2-nitro-nonadecanedioic acid, and 2-nitro-icosanedioic acid, or the salts or esters thereof.

2. The composition of claim 1 , wherein

a. succinic acid is present in an amount of from about 5 to about 18 wt %, glutaric acid is present in an amount of from about 8 to about 28 wt %, adipic acid is present in an amount of about 10 to about 29 wt %, pimelic acid is present in an amount of about 10 to about 20 wt %, and azelaic acid is present in an amount of about 8 to about 13 wt %, or an equivalent amount of the salts or esters thereof, and

b. if present, oxalic acid is present in an amount up to 10 wt %, if present suberic acid is present in an amount of to about 9 to about 20 wt %, if present sebacic acid is present in an amount of about 1 to about 10 wt %, if present undecanedioic acid is present in an amount of about 1 to about 8 wt %, if present dodecanedioic acid is present up to about 5 wt %, if present tridecanedioic acid is present up to about 4 wt %, if present tetradecanedioic acid is present up to about 2 wt %, and if present pentadecanedioic acid is present up to about 0.4 wt %, or an equivalent amount of the salts or esters thereof.

3. The composition of claim 1 , wherein

a. succinic acid is present in an amount of from about 10 to about 11 wt %, glutaric acid is present in an amount of from about 15 to about 18 wt %, adipic acid is present in an amount of about 16 to about 18 wt %, pimelic acid is present in an amount of about 15 to about 17 wt %, and azelaic acid is present in an amount of about 10 to about 12 wt %, or an equivalent amount of the salts or esters thereof, and

b. if present, oxalic acid is present in an amount up to 10 wt %, if present suberic acid is present in an amount of about 13 to about 15 wt %, if present sebacic acid is present in an amount of about 5 to about 9 wt %, if present undecanedioic acid is present in an amount of about 3 to about 6 wt %, if present dodecanedioic acid is present in an amount of about 1 to about 3 wt %, if present tridecanedioic acid is present in an amount of about 0.5 to about 1.5 wt %, if present tetradecanedioic acid is present up to about 0.2 wt %, and if present pentadecanedioic acid is present up to about 0.2 wt %, or an equivalent amount of the salts or esters thereof.

4. The composition of claim 1 , wherein

a. succinic acid is present in an amount of from about 5 to about 40 wt %, glutaric acid is present in an amount of from about 8 to about 27 wt %, adipic acid is present in an amount of about 10 to about 29 wt %, pimelic acid is present in an amount of about 10 to about 20 wt %, and azelaic acid is present in an amount of about 1 to about 13 wt %, or an equivalent amount of the salts or esters thereof, and

b. if present, oxalic acid is present in an amount up to 10 wt %, if present suberic acid is present in an amount of to about 4 to about 20 wt %, if present sebacic acid is present up to about 10 wt %, if present undecanedioic acid is present up to about 8 wt %, if present dodecanedioic acid is present up to about 5 wt %, if present tridecanedioic acid is present up to about 4 wt %, if present tetradecanedioic acid is present up to about 2 wt %, and if present pentadecanedioic acid is present up to about 0.4 wt %, or an equivalent amount of the salts or esters thereof.

5. The composition of claim 1 , wherein the acids are at least partially in the form of an alkaline metal salt.

6. The composition of claim 1 , wherein the acids are at least partially in the form of esters.

7. The composition of claim 6 , wherein the esters are C 1-4 alkyl esters.

8. The composition of claim 1 , wherein the acids are in the form of free acids.
