Definitions

  • the present invention relates to heavy-duty liquid laundry detergent compositions containing anionic synthetic surfactant, detergency builder, specific proteolytic enzyme and calcium ion.
  • the compositions provide improved cleaning performance, particularly through-the-wash, of enzyme-sensitive stains such as grass, blood, gravy and chocolate pudding.
  • Laundry detergents containing high levels of anionic surfactant and builder, and capable of providing superior cleaning performance are currently available. Some of these compositions also contain enzymes to enhance removal of enzyme-sensitive stains. However, it is believed that such compositions are enzyme-limited in that they can denature and expose stains to enzymatic action faster than currently available enzymes can cleave and break up the stains.
  • Enzyme performance can also be limited by a lack of adequate stability in liquid detergents.
  • the stabilization of enzymes is particularly difficult in built, heavy-duty liquid detergents containing high levels of anionic surfactant and water.
  • Anionic surfactants, especially alkyl sulfates, tend to denature enzymes and render them inactive.
  • Detergent builders can sequester the calcium ion needed for enzyme activity and/or stability.
  • the compositions can contain 10-60% surfactant, including anionics, and up to 40% builder.
  • U.S. Patent 4,404,115, Tai, issued September 13, 1983 discloses liquid cleaning compositions, preferably built liquid detergents, containing enzyme, 1-15% alkali metal pentaborate, 0-15% alkali metal sulfite, and 0-15% of a polyol having 2-6 hydroxy groups.
  • the compositions can contain 1-60% surfactant, preferably a mixture of anionic and nonionic in a weight ratio of 6:1 to 1:1, with or without soap.
  • the compositions also preferably contain 5-50% builder.
  • the compositions preferably contain from about 20% to 50% surfactant, which can be anionic. In a preferred embodiment, the compositions contain about 3% to 15% of a saturated fatty acid. They are othervise substantially free of builders, but can contain minor amounts of sequestrants.
  • the enzymes are said to be useful in laundry detergents, both liquid and granular. They can be combined with surfactants (including anionics), builders, bleach and/or fluorescent whitening agents, but there is no disclosure of specific detergent compositions.
  • Copending European Patent application EP-A-199 405 discloses liquid detergent compositions comprising the proteolytic enzymes herein and boric acid.
  • This invention relates to heavy-duty liquid laundry detergent compositions comprising, by weight:
  • the liquid detergents of the present invention contain, as essential components, anionic synthetic surfactant, detergency builder, specific proteolytic enzyme, calcium ion, and water.
  • the compositions herein provide improved cleaning performance, particularly through-the-wash, on enzyme-sensitive stains such as grass, blood, gravy and chocolate pudding.
  • anionic surfactant and builder in the present compositions provides an effective matrix for denaturing stains and exposing sites to enzymatic action.
  • the anionic surfactant is believed to be the primary denaturing agent, whereas the builder controls water hardness that would otherwise complex the anionic surfactant and interfere with its denaturing action.
  • the surfactant and builder matrix herein can denature and expose more sites on stains than currently available enzymes can cleave during the washing process. This is particularly true at low washing temperatures (e.g., in the range of 15°C to 35°C) where enzymes are catalytically slow.
  • the present proteolytic enzymes appear to be superior to other proteases in catalytic efficiency. They thus can take advantage of the stain denaturing power of the compositions herein and provide significant stain removal benefits. In contrast, they provide little or no benefits in detergent compositions containing less anionic surfactant and builder.
  • compositions of the present invention contain from 7% to 50%, preferably from about 10% to about 40%, and most preferably from about 15% to about 30%, by weight of an anionic synthetic surfactant.
