This study relates to develop protein surfactants having high foaming stability, cleaning properties, biodegradation and safety. Protein surfactants have provided a means of retaining the mildness of the nonionic surfactants, maintaining the foaming power and detergency of anionic surfactants. Protein surfactants have the potential for use as surfactants, but the potential has been limited by the cost of their commercial preparation. A series of long chain acyl peptides were easily prepared by treating an acid chlorides with the appropriate peptides in an aqueous system. Two series of acylated glycines and peptides[(1) the acyl glycine derivatives, varying the length and nature of the acyl chain(acyl glycine); (2) The capryloyl, lauroyl, palmitoyl and stearoyl derivatives of peptides(acyl peptide-185, acyl peptide-245, acyl peptide-300 and acyl peptide-410)] were synthesized and purified.
