The present invention relates to microemulsions and methods of preparing and using the microemulsions.

Surfactant microemulsions

Monomeric and oligomeric compounds of Formula (I) comprising hydrophobic alkyl or alkenyl ester moieties and hydrophilic carboxylate moieties: wherein Ris C-Calkyl, Ris C-Calkyl or C-Calkenyl, Y is a cation, Z is a sulfur-containing moiety, and n and k are integers as defined herein. The compounds of Formula (I) have surfactant properties. Also provided are compositions comprising the compounds of Formula (I), and methods of using the compounds or compositions for cleaning purposes.

Anionic surfactants

Hydrocarbyl terminated polyester compounds comprising sulfur-containing repeat units that are useful as plastic modifiers, polymer blend compositions comprising the hydrocarbyl terminated polyester compounds, methods for modifying the performance properties of polymers, and methods for preparing the hydrocarbyl terminated polyester compounds.

Plastic modifiers

Methods for using sulfur-containing compounds comprising short chain aliphatic ester or amide moieties as solvents and compositions comprising these compounds are provided.

Sulfur-containing compounds as solvents

Formulations comprising hydroxy methionine analog and having low levels of sulfate ions and bisulfate salts, processes for preparing the formulations, compositions comprising the formulations, and methods of using the formulations.

Hydroxy methionine analog formulations suitable for specialty chemical applications

The present invention provides sulfoxide compounds comprising hydrophobic ester or amide moieties such that the compounds have surfactant properties. Also provided are methods for using the sulfoxide compounds or mixtures of the sulfoxide compounds in a variety of applications.

Sulfoxide-based surfactants

The present invention provides sulfur- or selenium-containing compounds comprising hydrophobic moieties and ethoxylated ester or ethoxylated amide moieties such that the compounds have surfactant properties. Also provided are methods for using the disclosed compounds or mixtures thereof in a variety of applications.

Ethoxylated surfactants

Antimicrobial compositions comprising sulfur- or selenium-containing, fatty-acylated alpha-hydroxy acid compounds and methods of using said compounds or compositions to inhibit microbial growth.
