  • Patent number: 5954998
    Abstract: A stable liquid peracid precursor composition for delivering a bleaching and cleaning material is provided in which the liquid peracid precursor composition combines a dispersion medium which comprises a stabilizing effective amount of a liquid matrix and an emulsifier, and a dispersed phase that comprises a peracid precursor. The bleaching and cleaning material comprises either a hydrophobic or hydrotropic generated mono- or diperoxyacid, or mixtures thereof.
    Type: Grant

  • Patent number: 5814242
    Abstract: Preferred embodiments of the invention are heterocyclic cationic activators with the structure of Formula I ##STR1## wherein A is a saturated ring formed by a plurality of atoms in addition to the N.sub.1 atom, the saturated ring atoms including at least one carbon atom and at least one of O, S, and N atoms, the substituent R.sub.1 bound to the N.sub.1 atom of the Formula I structure including either (a) a C.sub.1-24 alkyl or alkoxylated alkyl where the alkoxy is C.sub.2-4, (b) a C.sub.4-24 cycloalkyl, (c) a C.sub.7-24 alkaryl, (d) a repeating or nonrepeating alkoxy or alkoxylated alcohol, where the alkoxy unit is C.sub.2-4, or (e) --CR.sub.2 R.sub.3 C.tbd.N where R.sub.2 and R.sub.3 are each H, a C.sub.1-24 alkyl, cycloalkyl, or alkaryl, or a repeating or nonrepeating alkoxyl or alkoxylated alcohol where the alkoxy unit is C.sub.2-4, the R.sub.2 and R.sub.3 substituents being each H, a C.sub.

  • Patent number: 4972017
    Abstract: A polymeric film material for the rinse release of wash additives comprises a blend of polyvinyl alcohol and an alkyl cellulose. A metalloid oxide cross-linking agent is present in an amount sufficient to sharply reduce the solubility rate of the film blend in an alkaline wash, yet allow dissolution in a less alkaline rinse. Optionally, a hydrophobic cationic species is included to further reduce the dissolution rate in the wash pH. The films remain intact during normal wash cycles and over a range of typical water temperatures, then rapidly dissolve in the rinse. The film can be used to microencapsulate an additive, or made into a water-soluble pouch, or as a soluble seal for a pouch or container.

  • Patent number: 4828744
    Abstract: Conventional polyvinyl alcohol envelopes will not readily dissolve in wash water which has a significant borate concentration and a pH frequently encountered in wash liquors. Herein, such films are rendered sufficiently soluble in such solutions. In the preferred embodiment this is done by utilizing a polyvinyl alcohol film wherein at least a portion of the polyvinyl alcohol has a number average molecular weight below about 50,000, or a polyvinyl alcohol film containing a polyhydroxy compound having a binding constant with borate of at least about 800M.sup.-2, or utilizing a polyvinyl alcohol film having an acid having an acid dissociation constant of 10.sup.-9 M or larger; or a polyvinyl alcohol film containing mixtures thereof.

  • Patent number: 4561993
    Abstract: A thixotropic cleaner comprising about 6 to 12% of a precipitated silica; about 0.05 to 2.5% of a cationic, nonionic or zwitterionic or amphoteric surfactant, or mixtures thereof, that has the ability to hydrogen bond and mixtures thereof; an acid; and an abrasive.The relationship between the relatively narrow ranges of precipitated silica and hydrogen bonding surfactant is critical and responsible for the favorable viscosity, ability to suspend abrasives, and minimal or lack of syneresis. All of these advantageous characteristics are stable over an extended period of time.

  • Patent number: 4457855
    Abstract: This invention relates to dyes which are resistant to hypochlorite attack, exemplary of which are anthraquinone dyes of the general formula: ##STR1## wherein X.sub.1, X.sub.2, X.sub.3, X.sub.4, R.sub.5, R.sub.6, R.sub.7, and R.sub.8 are defined within the specification. The invention also relates to hydrophobic latex particles, such as polyethylene, in which such dyes are deposited. A combined liquid bleaching and dyeing composition is disclosed which includes the aforementioned particles in hypochlorite liquid bleach at a pH above about 11. This composition has sufficiently long shelf life for the purposes of ordinary commerce.
