Definitions

  • the present invention is directed to laundry detergent compositions, and more particularly to laundry detergent compositions comprising a surfactant blend of personal care surfactants which surprisingly inhibits dye transfer, while maintaining high cleaning capabilities without the need of a separate polymeric dye transfer inhibition agent.
  • One of the major problems associated with laundry detergent compositions is the tendency of some colored fabrics to release dyes into the launder liquor during the laundering process.
  • the released dyes (or so-called fugitive dyes) are typically transferred onto other fabrics which oftentimes have colors that are completely different than the fugitive dyes. Dye transfer may thus cause unwanted discoloration of other fabrics present in the laundering process.
  • the original dyed fabric begins to fade and/or, if the released dye is absorbed in other areas of the original dyed fabric, discoloration of the dyed fabric may also occur.
  • a well known solution to the dye transfer problem described above is to complex and/or absorb the released dyes before the dyes have a chance to become attached to other fabric articles in the laundry liquor.
  • various water-soluble polymers have been added to prior art detergent compositions in order to inhibit dye transfer.
  • EPA 372 291 discloses a process for washing discoloration-sensitive fabrics in which the washing solution contains several water-soluble polymers such as N-vinylimidazole, N-vinyloxazolidone, N-vinylpyrrolidone and copolymers thereof to inhibit dye transfer.
  • Detergent compositions generally comprise anionic surfactants.
  • Prior art water-soluble polymeric dye transfer inhibition (DTI) agents are believed to interact with monomers of the anionic surfactant, thereby reducing the overall dye transfer inhibition performance.
  • nonionic surfactants are typically added to reduce the level of the monomers of the anionic surfactant.
  • the addition of nonionic surfactants to the detergent composition thus stabilizes the dye transfer inhibition agent.
  • DTI stabilizers are continuously being sought.
  • WO 98/53034 discloses a laundry detergent composition which includes a dye transfer inhibition agent such as polyvinylpyrrolidone (PVP) .
  • PVP polyvinylpyrrolidone
  • the DTI stabilizing agent disclosed in this reference is a combination of surfactants selected from amphoteric, zwitterionic, semipolar surfactants and mixtures thereof. The reference does not disclose however that the DTI stabilizing surfactants can be employed alone to inhibit dye transfer during the laundering process. Indeed, in all the reference examples, a water-soluble polymer such as PVP is employed to prevent dye transfer.
  • WO 98/53034 may prevent dye transfer, it requires the presence of an extra component, i.e., a DTI stabilizing surfactant, which adds to the overall cost of the final product. In addition to increased cost, extra processing steps are needed to manufacture the same.
  • the present invention provides a surfactant blend comprising personal care surfactants which quite unexpectedly can be used with various detergent surfactants to substantially inhibit dye transfer.
  • the surfactant blend of the present invention can also function as a cleaning agent in various detergent compositions.
  • the inventive surfactant blend serves multiple roles in the detergent composition.
