Definitions

  • the present invention relates to heavy-duty liquid detergents containing anionic synthetic surfactant, fatty acid, water-soluble detergency builder, proteolytic or amylolytic enzyme, boric acid or a boron compound capable of forming boric acid in the composition, and calcium ion.
  • Boric acid has been found to provide improved enzyme stability in the built, anionic-based compositions herein.
  • the stabilization of enzymes is particularly difficult in built, heavy-duty liquid detergents containing high levels of anionic surfactants 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, O ⁇ 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.
  • Japanese Patent Application J78028515 assigned to Nagase and Co., Ltd., published August 15, 1978, discloses liquid detergents containing sorbitol and borax as an enzyme-stabilizing system.
  • EP-A-0 028 865, Polfo and Barrat relates to homogeneous aqueous enzyme-containing liquid detergents containing saturated fatty acids, minute level of enzyme accessible calcium and low level of short chain carboxylic acid, especially formic acid.
  • This invention relates to heavy-duty liquid detergent compositions comprising, by weight:
  • the liquid detergents of the present invention contain, as essential components, anionic synthetic surfactant, fatty acid, water-soluble detergency builder, proteolytic or amylolytic enzyme, boric acid or a boron compound capable of forming boric acid in the composition, calcium ion, and water.
  • Boric acid provides superior enzyme stability in the built, anionic-based liquid detergents herein. While not intending to be limited by theory, it is believed that boric acid and calcium form intramolecular bonds which effectively cross-link or staple an enzyme molecule together, thereby holding it in its active spatial conformation. Surprisingly, boric acid appears to be a better enzyme stabilizer in the present compositions than in compositions which are less stressful to enzymes, such as those containing less anionic surfactant and little or no builder.
  • compositions of the present invention contain from 10% to 50%, preferably from 12% to 35%, and most preferably from 15% to 25%, by weight of an anionic synthetic surfactant.

  • Boric acid is believed to be particularly effective at stabilizing enzymes in such stressful compositions.
  • compositions herein can optionally contain other synthetic surfactants known in the art, such as the nonionic, cationic, zwitterionic, and ampholytic surfactants described in the above-cited Barrat et al and Laughlin et al patents.
  • a preferred cosurfactant used at a level of from 2% to 25%, preferably from 3% to 15%, more preferqbly from 4% to 10%, by weight of the composition, is an ethoxylated nonionic surfactant of the formula R 1 (OC 2 H 4 ) n OH, wherein R 1 is a C 10 ⁇ C 16 alkyl group or a C S -C 12 alkyl phenyl group, n is from 3 to 9, and said nonionic surfactant has an HLB (hydrophile-lipophile balance) of from 10 to 13.
