摘要:
A method of conditioning fabrics with a composition containing novel agents which contain either an ester or a NH link between a glyceric carboxyl group and a quaternary ammonium group is described. The compounds based on glyceric acid are both effective fabric conditioners and biodegradable, and may be formulated in any conventional physical form to form the fabric conditioning composition.

A method of using the composition is also described.

A class of malonates having the structures: ##STR1## has been identified as providing effective bleach precursors. These precursors are employed in conjunction with a peroxygen compound.
摘要:
A bleach precursor compound, its peroxygen acid derivative, and detergent compositions containing these materials are disclosed herein. The bleach precursor structurally comprises a quaternized ammonium or phosphonium group linked to a carbonate moiety having a leaving group. Upon perhydrolysis in the presence of hydrogen peroxide and a basic aqueous media, there is generated a peroxycarbonic acid bleach.

Water-treatment compositions are provided which contain a water-soluble, water-treatment polymer and, optionally, additional water-treatment chemicals. The polymers are prepared from water-treatment monomers and a photo-inert, latently-detectable moiety which is covalently bonded to the polymer backbone. When the residue of the photo-inert moiety is contacted with an amount of a photoactivator which is effective to cause the residue of the photo-inert moiety to absorb within a wavelength ranging from 300 to 800 nanometers, the residue of the photo-inert moiety is detectable at concentrations of less than 100 parts per million. Methods are also provided which allow for the determination of the concentration of low levels, i.e., less than 100 ppm, of the water-treatment polymer present in an aqueous system.
摘要:
For use in microelectronics applications, an improvement to an epoxy resin composition to reduce bleeding of the composition when it is applied to a silicon or metal substrate consists in the addition to the composition of a polyhydroxyl compound having two or three hydroxyl groups, or of a monohydroxyl compound that also contains one or more phenyl groups. The hydroxyl compound is present in the composition in a ratio by weight to the flexibilizing compound of from 1:3 to 1:10.
摘要:
Latex binders are disclosed which are used to prepare freeze-thaw-stable latex coating compositions which may be free of volatile freeze-thaw/open-time additives. The latex binders are prepared by combining a polymer which is the polymerization product of a polymerizable saccharide monomer, an acrylic monomer and, optionally, a monomer selected from styrenic monomers, ionic monomer and wet adhesion monomers. The latex coating compositions are freeze-thaw stable, even in the total absence of a volatile freeze-thaw additive, and exhibit improved open-time when compared to a latex coating composition which does not contain a volatile freeze-thaw additive. Methods for preparing the freeze-thaw-stable latex coating compositions are also disclosed.
