Surface active acylated amidated peptides and polypeptides

Claim 1

A METHOD FOR MANUFACTURING SURFACE ACTIVE COMPOSITIONS, WHICH COMPRISES: HEATING AND REACTING AN AMINESUPPLYING COMPOSITION HAVING AT LEAST ONE ACYLATABLE AMINO HYDROGEN AND SELECTED FROM THE GROUP CONSISTING OF WATER-SOLUBLE ALIPHATIC ALKYLOLAMINES AND WATER-SOLUBLE ALIPHATIC POLYAMINES WITH A PROTEINACEOUS COMPOSITION HAVING MORE THAN ONE PEPTIED GROUP UNDER CONDITIONS SUCH THAT THERE IS PRESENT DURING THE REACTION LESS THAN 20% WATER BASED ON THE WEIGHT OF SSAID PROTEINACEOUS COMPOSITION, SAID REACTION BEING CARRIED OUT BY REMOVING WATER OF CONDENSATION FROM THE REACTION MIXTURE AND CONDUCTING THE REACTION UNTIAL AN ALIQUOT PART OF THE REACTION PRODUCT IS SOLUBLE IN A DILUTE AQUEOUS ACID, WHEREBY WATER-SOLUBLE AMIDES OF THE CNSTITUENT AMINO ACIDS AND POLYPEPTIDES OF SAID PROTEINACEOUS COMPOSITION ARE FORMED; FURTHER HEATING AND REACTING SAID AMIDATED AMINO ACIDS AND POLYPEPTIDES WITH AN ACYLATING AGENT SELECTED FROM THE GROUP CONSISTING OF FATTY ACIDS, FATTY ACID ESTERS AND MIXTURES THEREOF TO A TEMPERATURE AND FOR A TIME SUFFICIENT TO SPLIT OUT WATER WHEN SAID ACYLATING AGENT IS A FATTY ACID AND TO A TEMPERATURE AND FOR A TIME SUFFICIENT TO SPLIT OUT AN ALCOHOL WHEN SAID ACYLATING AGENT IS A FATTY ACID ESTER, WHEREBY ACYLATED AMIDES OF THE CONSTITUENT AMINO ACIDS AND POLYPEPTIDES OF SAID PROTEINACEOUS COMPOSITION ARE FORMED.
