Synthesis of keratin foaming agent

Abstract

The samples of technical protein foaming agents based on keratin materials like wool were obtained
by method of alkaline hydrolysis. The optimal parameters for the hydrolysis of keratin-containing raw
materials were established: the duration of the process was 3 hours, the concentration of the NaOH reagent
solution was 5%, the reaction temperature was 403K, the feedstock ratio was NaOH = 1:7.5. Conducted
by IR-spectroscopic studies of the hydrolysis reaction products were shown the identify of the samples
of keratin foaming agents, obtaining at 403K and at 433K. It is established that at a temperature above
403K the quality of the product of hudrolysis significantly not improve. Proposed structure of the samples
has α-helical configuration of laying chain and samples of amino acids with peptide bonds. The samples
obtained by hydrolysis of keratin materials are natural surfactants and after modification ther can used as
foaming agents in fire fighting and foamers for construction.
