Abstract
The present disclosure provides siloxane derivatives of amino acids that have 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 with a siloxane group to form a compound that is surface-active and has surfactant characteristics. The compounds have low critical micelle concentrations (CMC) as well as the ability to lower the surface tension of a liquid.
Claims15
A liquid medium, comprising:
- water;
- and
- a compound of Formula I:
- wherein R1 and R2 are the same or different, and comprise at least one group selected from the group consisting of C1-C6 alkyl, optionally the C1-C6 alkyl may include one or more of oxygen, nitrogen, or sulfur atoms or groups that include at least one of these atoms, and the alkyl chain may be optionally substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;
- R3 is selected from the group consisting of alkenyl, alkynyl, ester, alcohol, aryl alkyl, alkoxy alkyl ether, alkyl phosphate, C3-C8 carboxylic acid, C1-C10 alkyl benzoic acid, and a C1-C6 linker attached to a second molecule of Formula I, wherein the second molecule is the same or different;
- n is an integer from 1 to 12;
- and
- X is selected from the group consisting of chloride, bromide, and iodide.
