  • Patent number: 6225273
    Abstract: Disclosed are photochemical super oxide generators useful as photobleaches for laundry detergent compositions and as photobleaches or photodisinfectants for use in hard surface cleaning compositions. The compounds described herein comprise an amino-containing electron transfer moiety bonded to the photosensitizing unit wherein the amino-containing moiety is capable of transferring an electron to the photochemically excited &pgr; electron cloud of the photosensitizer unit thereby enabling superoxide formation.

  • Patent number: 6099589
    Abstract: In fabric laundry procedures, commercial and household laundry detergent compositions commonly contain an optical brightener composition. Brighteners adjust the optical properties of the fabric in such a way that the fabric appears to be white even after repeated washings. Often white fabrics can yellow during use. Fluorescent optical brighteners having an optical blue aspect, mask the yellowing of the fabric. Common laundry detergents fail to have sufficient brightening capacity to brighten heavily soiled white cotton items used in household, commercial, institutional or fast-food food surface. A process for improving the whiteness of soiled white cotton, preferably terry cloth, items involves contacting the soiled white fabric item with a presoak containing an effective proportion of a fluorescent optical brightener composition, removing the item from the presoak and separating the presoak composition from the fabric item producing an extracted item.

  • Patent number: 5972038
    Abstract: The performance of photobleaches such as the zinc phthalocyanines is enhanced by means of alkylene amino/carboxylate or alkylene amino/phosphonate chelants. Thus, sulfonated zinc phthalocyanine plus diethylenetriamine pentaacetate provide enhanced photobleaching of laundered fabrics. Detergent compositions comprising the improved photobleach systems are provided.
