Described herein are hemi-aminal ethers and thioethers of N-alkenyl cyclic compounds that may be produced through a reaction comprising: (A) at least one first reactant represented by a structure (I), wherein X is a functionalized or unfunctionalized C1-C5 alkylene group optionally having one or more heteroatoms, and each R1, R2, and R3 is independently selected from the group consisting of hydrogen and functionalized and unfunctionalized alkyl groups optionally having one or more heteroatoms, and (B) at least one second reactant having at least one hydroxyl moiety or thiol moiety. The hemi-aminal ethers and thioethers of N-alkenyl cyclic compounds may comprise a polymerizable moiety, in which case they may be left as-is or used to create homopolymers or non-homopolymers, or they may not comprise a polymerizable moiety. A wide variety of formulations may be created using the hemi-aminal ethers and thioethers of N-alkenyl cyclic compounds, including personal care, oilfield, and construction formulations.
The present invention relates to esterified glycerylated alkyl glycoside and to a process for making same. The esterified glycerylated alkyl glycoside have one or more polyglyceryl moieties and one or more acyl moieties, wherein all of the one or more acyl moieties are situated on the one or more polyglyceryl moieties via an ester linkage. These compounds have been found to be useful as emulsifiers and coemulsifiers in the formulation of a phase stable emulsions suitable for use in personal care, home care, industrial and institutional, and health care applications.

The present invention relates to an amphiphilic hybrid delivery system in micellar form for delivery of agrochemicals, based on a hydrophilic polyethylene glycol (PEG) polymer conjugated to a hydrophobic dendron, the dendron comprising at least one pH-dependent or enzymatically cleavable hydrophobic end group that is covalently attached to the dendron, wherein the micelle disassembles upon enzymatic or pH-dependent cleavage of the hydrophobic end group. The hydrophobic end group that is conjugated to the dendron may comprise an agrochemical, and/or the micelle may (non-covalently) encapsulate an agrochemical. The present invention further provides methods of use thereof and to a kit comprising same.
Thiocarbonate compounds which, in one embodiment, are utilized as a rheology modifier or associative thickener. The thiocarbonate compounds thicken or increase the viscosity of a composition, preferably an aqueous composition when used in an effective amount. In one preferred embodiment, the thiocarbonate compounds include at least one hydrophilic group containing repeat unit such as derived from acrylic acid, and at least one hydrophobic group to enhance association with other compounds and thus increase viscosity of a composition. Aqueous composition comprising a latex and thiocarbonate associative thickeners are described.
Disclosed are multi-purpose polymers that are the polymerization product of a monomer mixture comprising at least one amino-substituted vinyl monomer; at least one nonionic vinyl monomer; at least one associative vinyl monomer; at least one semihydrophobic vinyl surfactant monomer; and, optionally, comprising one or more hydroxy-substituted nonionic vinyl monomer, crosslinking monomer, chain transfer agent or polymeric stabilizer. These vinyl addition polymers have a combination of substituents, including amino substituents that provide cationic properties at low pH, hydrophobic substituents, hydrophobically modified polyoxyalkylene substituents, and hydrophilic polyoxyalkylene substituents. The polymers provide surprisingly beneficial Theological properties in acidic aqueous compositions, and are compatible with cationic materials. Additionally, this invention relates to the incorporation of a basic material after the addition of an acidic material to reduce the pH of the composition without negatively impacting the viscosity of the composition. The multi-purpose polymers are useful in a variety of products for personal care, health care, household care, institutional and industrial care, and industrial applications.
