Claims13
An adhesive composition comprising:
- lysine, alpha ketoglutaric acid, and water,
- wherein the lysine and the alpha ketoglutaric acid are present in the form of an aqueous salt solution and do not form precipitates in the adhesive composition.
An adhesive composition comprising
- lysine, alpha ketoglutaric acid, and water, wherein
- a mixing molar ratio of the lysine to the alpha ketoglutaric acid is in a range of 1.7:1 to 1:3 such that a precipitate does not form in the adhesive composition if the adhesive composition is stored at a temperature of −18° C. or greater and less than 40° C. for 14 days or longer.
A method of preparing an adhesive composition, the method comprising:
- mixing lysine, alpha ketoglutaric acid, and water to prepare a mixture;
- and
- stirring the mixture at a temperature of less than 40° C.,
- wherein the respective contents of the lysine, the alpha ketoglutaric acid, and the water are adjusted such that precipitates of lysine and alpha ketoglutaric acid do not form in the adhesive composition.
