  • Publication number: 20230265112
    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.

  • Publication number: 20100264364
    Abstract: The invention comprises a method of enhancing viscosity and/or viscoelasticity of surfactant solution using nanoparticles. The particle allow a formulator to tailor-make a solution of defined rheology (viscosity and/or viscoelasticity) using nanoparticles to control these properties. Further, the particles allow independent control of each of the variable and further allow the variable to be controlled without use of additional surfactants, polymer and other components traditionally used for this end. The invention also comprises compositions thereof.
