Abstract
Official abstract text for this publication.
The present invention provides a method of producing an aqueous solution containing an N—C 8-22 acyl acidic amino acid and/or a salt thereof and having pH 8.4-9.5, including the first step for reacting an acidic amino acid and/or a salt thereof with a C 8-22 fatty acid chloride in a water solvent at pH 10-13 to form an N—C 8-22 acyl acidic amino acid salt, and the second step for adjusting the pH of the aqueous solution after the first step to 8.4-9.5.
First claim
Opening claim text (preview).
The invention claimed is: 1. A detergent comprising an aqueous solution, wherein said aqueous solution comprises: (A) 1.0 to 10.0 wt % of at least one member selected from the group consisting of an acidic amino acid and a salt of an acidic amino acid: (B) 10.0 to 30.0 wt % of at least one member selected from the group consisting of an N—C 8-22 acyl acidic amino acid and a salt of an N—C 8-22 acyl acidic amino acid; and (C) 0.5 to 5.0 wt % of at least one member selected from the group consisting of an N—C 8-22 acyl acidic amino acid dipeptide and a salt of an N—C 8-22 acyl acidic amino acid dipeptide, and said aqueous solution has pH of 8.4 to 9.5. 2. The detergent according to claim 1 , wherein said aqueous solution further comprises at least one member selected from the group consisting of an N—C 8-22 acyl acidic amino acid tripeptide and a salt of an N—C 8-22 acyl acidic amino acid tripeptide. 3. The detergent or starting material thereof according to claim 1 , wherein said aqueous solution further comprises at least one member selected from the group consisting of a C 8-22 fatty acid and a salt of a C 8-22 fatty acid. 4. The detergent according to claim 2 , wherein said aqueous solution further comprises at least one member selected from the group consisting of a C 8-22 fatty acid and a salt of a C 8-22 fatty acid. 5. The detergent according to claim 1 , wherein said aqueous solution is substantially free of a hydrophilic organic solvent.
