A method of making a stable formulation of salicylic acid and chitosan, comprising the steps of:
- adding hydrolyzed chitosan to a first aqueous solution to form a second aqueous solution, wherein the first aqueous solution comprises salicylic acid and an inorganic base in an amount sufficient to stabilize the salicylic acid;
- and
- adding humic acid to the second solution in an amount sufficient to stabilize the hydrolyzed chitosan, whereby a stable formulation is formed which comprises at least about 4% salicylic acid and wherein:
- the salicylic acid and the hydrolyzed chitosan are present in a molar ratio of about 2:1;
- the inorganic base and the salicylic acid are present in a molar ratio of about 1:1;
- and
- the humic acid is present in an amount sufficient to stabilize the hydrolyzed chitosan.
A method of making a stable formulation of salicylic acid and chitosan, comprising the steps of:
- adding hydrolyzed chitosan to a first aqueous solution to form a second aqueous solution, wherein the first aqueous solution comprises salicylic acid and an inorganic base in an amount sufficient to stabilize the salicylic acid;
- and
- adding humic acid to the second solution in an amount sufficient to stabilize the hydrolyzed chitosan, whereby a stable formulation is formed which comprises at least about 2% hydrolyzed chitosan and wherein:
- the salicylic acid and the hydrolyzed chitosan are present in a molar ratio of about 2:1;and
- the inorganic base and the salicylic acid are present in a molar ratio of about 1:1.
A method of making a stable aqueous formulation of salicylic acid and chitosan, comprising the steps of:

- and
- adding humic acid to the second solution in an amount sufficient to stabilize the hydrolyzed chitosan, whereby a stable formulation is formed which comprises about 31% salicylic acid and about 16% hydrolyzed chitosan.
A stable aqueous formulation, comprising:
- at least about 4% salicylic acid;
