    Abstract: A poly-lysine derivative obtained by a process comprising the steps of (a) heating an aqueous lysine solution to boiling (b) increasing temperature of the aqueous lysine solution to a reaction temperature in the range of about 105°C to about 180°C (c) keep the reaction temperature in the range of about 105°C to about 180°C until i. melt viscosity of the reaction mixture in the range of about 350 m Pa*s to about 6,500 m Pa*s when measured at 160°C and ii. an amine number in the range of about 100 mg KOH/g to about 500 mg KOH/g is achieved (d) optionally, the vacuum applied is released (e) add alkyl-carboxylic acid or alkenyl-carboxylic acid in amounts of 2.5 mol% to 10 mol%, relative to the theoretical amount of poly-lysine comprised in the reaction mixture (f) increase or keep the reaction temperature in the range of about 105°C to about 180°C until number of free alkyl-carboxylic acid or alkenyl-carboxylic acid is ≤ 9% by weight, relative to the total weight of the reaction mixture. wherein vacuum is applied either in step (a), (b) and/or (c) and water is removed continu- ously during the whole process.
