Abstract

Official abstract text for this publication.

The present disclosure provides derivatives of amino acids that have branched alkyl structures and surface-active properties. The amino acid can be naturally-occurring or synthetic, or they may be obtained via a ring-opening reaction of a lactam, such as caprolactam. The amino acid may be functionalized to form a compound that is surface-active and have advantageous surfactant characteristics. The compounds of the present disclosure have low critical micelle concentrations (CMC) as well as superior ability to lower the surface tension of a liquid.

First claim

Opening claim text (preview).

The invention claimed is: 1. A surfactant compound 6-((2-butyloctyl)oxy)-6-oxohexan-1-aminium chloride, having the following formula: and having a critical micelle concentration (CMC) of about 0.15 mmol in water. 2. The compound of claim 1 , having a surface tension in water equal to or less than 49 mN/m at a surface age of 1,000 ms or greater. 3. A liquid composition comprising: water; and the surfactant compound 6-((2-butyloctyl)oxy)-6-oxohexan-1-aminium chloride, having the following formula: and having a critical micelle concentration (CMC) of about 0.15 mmol in water. 4. The liquid composition of claim 3 , wherein the surfactant compound has a surface tension in water equal to or less than 49 mN/m at a surface age of 1,000 ms or greater.
