Definitions

  • This invention relates broadly to bleaching compositions. More particularly, this invention relates to bleaching compositions which derive their bleaching activity from a compound having an active oxygen content. Still more particularly, this invention relates to peroxyacid bleaching compositions.
  • Peroxygen bleaching agents in general and peroxyacid compounds in particular have long been recognized as effective bleaching agents for use when the adverse color and fabric damage effects of harsh active halogen bleaching agents cannot be tolerated. See, for example, Canadian Pat. No. 635,620, issued January 30,1962, to McCune. U.S. Pat. No. 3,414,593, issued December 3,1968, to Robson, discloses alpha-sulfo peroxy fatty acid compounds as detergents and bleaching agents.
  • Peroxyacid bleach compositions having increased solubility are also disclosed in U.S. Pat. No. 4,126,573, November 21, 1978, to Johnston.
  • 1,687,804 discloses that inorganic and organic peroxide which has a high proportion of available oxygen but an ordinarily low efficacy as a bleach may be activated by the addition of 1-20% of an organic peroxide which is a more active bleach.
  • the preferred activating organic peroxyacids are the fatty acids.
  • hydrophilic peroxyacid bleaches are effective bleaches for hydrophilic soils, but ineffective for bleaching hydrophobic soils, and vice versa, hydrophobic peroxyacid bleaches are more effective on hydrophobic soils.
  • hydrophobic peroxyacid bleaches are more effective on hydrophobic soils.
  • other peroxyacid bleaches, hydrotropic are somehwere in between the hydrophilic and hydrophobic bleaches in effectiveness on a particular type of soil. Bleaching ineffectiveness on a particular type of soil equates with poorer overall bleaching. This problem has not been recognized and addressed in modern peroxyacid bleach art.
  • the present invention is directed to a laundry bleach comprising a mixture of peroxyacid bleaches of general formulae wherein R, and R 2 are alkylene groups containing from 1 to 20 carbon atoms, or phenylene groups and X and Y are hydrogen, halogen, alkyl, aryl, alkylammonium or a group which provides an anionic moiety in aqueous solution, said mixture being selected from
  • the two essential components of the present invention are at least two peroxyacid compounds selected from different classes of peroxyacids. These will be described in turn below.
  • the peroxyacid bleach composition of the instant invention comprises a mixture of at least two peroxyacid compounds.
  • the preferred peroxyacid compounds are "normally solid", i.e., dry or solid at room temperature.
  • the peroxyacid compounds of the present invention in general, are the organic peroxyacids, water-soluble salts thereof which yield a species containing a -0-- moiety in aqueous solution, and adducts of the organic peroxyacids and urea.
  • R, and R 2 are alkylene groups containing from 1 to about 20 carbon atoms or phenylene groups
  • X and Y are hydogen, halogen, alkyl, aryl, alkylammonium or any group which provides an anionic moiety in aqueous solution.
  • Such X and Y groups can include for example, wherein M is H or a water-soluble, salt-forming cation. It is preferred that the acids used in the present invention be dried to a moisture level lower than 1.0%, and preferably lower than 0.5%.
  • peroxyacids are classified as either (1) hydrophilic, (2) hydrophobic, or (3) hydrotropic. These classifications are based on their different levels of effectiveness on real world soils.
  • Real world soils contain hydrophilic and/or hydrophobic components.
  • a hydrophilic bleach is most effective on a hydrophilic bleachable soil, such as tea (tannic acid based), fruit juices, and the like.
  • hydrophobic bleaches are most effective on hydrophobic bleachable soils, such as body soils (fatty acid/ triglyceride based).
  • Hydrotropic bleaches find utility on both types of soils, but are less effective on hydrophilic soils than hydrophilic bleaches and less effective on hydrophobic soils than hydrophobic bleaches. Combinations of peroxyacids of the different classes result in better overall bleaching than is achieved with a single peroxyacid.
  • the "hydrophilic bleach” is defined as a peroxyacid whose parent carboxylic acid (or the salts thereof): (1) has no measurable critical micelle concentration (CMC) below 0.5 moles per liter (M/1) and (2) has a chromatographic retention time of less than 5.0 minutes under the following high pressure liquid chromatographic (HPLC) conditions:
  • hydrophobic bleach is defined as a peroxyacid whose parent carboxylic acid (or salts thereof) has a CMC of less than 0.5M.
  • the "hydrotropic bleach” is defined as a peroxyacid whose parent carboxylic acid (or salts thereof) has no measurable CMC below 0.5M and has a chromatographic retention time of greater than 5.0 minutes under the HPLC conditions described above.
  • the CMC is measured in aqueous solution at 20°-50°C.
  • hydrophobic peroxyacid bleaches there been found that those which have a long hydrocarbon chain with the percarboxylate group at one end (e.g., perlauric acid) tend to be more effective (on an equal available oxygen basis) in the bleaching of hydrophobic stains from fabrics than those which are not constructed in this way, e.g., peroxybenzoic acid and diperoxydodecanedioic acid.
  • the long chain peroxyacids with the percarboxylate groups at one end have a structure similar to surface active agents (surfactants). It is believed that in a washing solution, their hydrophobic "tail” tends to be attached to the hydrophobic stains on the fabrics, thereby causing a localized increase in bleach concentration around the stain and thus resulting in increased efficiency in bleaching for a given concentration of active oxygen in the bleaching solution.
  • surface active agents surfactants
  • surfactants be present in the bleaching solutions in which the peroxyacids are used.
  • Surfactants should generally be present in the bleaching solution at a level of at least 150 ppm. It is the usual practice to bleach fabrics in a laundering solution which contains a laundry detergent. Such detergents contain surfactants and are generally used at solution concentrations which provide more than 200 ppm surfactant to the solution. Thus, if the bleach compositions herein are to be used with a laundry detergent there is no need to incorporate a surfactant into the bleach composition.
  • surfactants are incorporated into the bleach compositions herein they will generally be present at levels of from 0.5% to 60%, preferably from 20% to 30% of the composition. Examples of suitable surfactants are given below.

  • the complex aluminosilicates i.e., zeolite-type materials
  • zeolite-type materials are useful detergency builders herein in that these materials soften water, i.e., remove hardness ions.

  • a description of zeolite materials and a method of preparation appear in U.S. Pat. No. 2,882,243, Milton, issued April 14,1959.
  • aminophosphonate stabilizers which are commercially available compounds sold under the names Dequest 2000, Dequest 2041 and Dequest 2060, by The Monsanto Company, St. Louis, Missouri. (Dequest is a Registered Trade Mark). These compounds have the following structures:
  • aminophosphonate compounds can be used in their acid form, represented by the above formulas, or one or more of the acidic hydrogens can be replaced by an alkali metal ion, e.g., sodium or potassium.
  • Additional stabilizers can also be used, primarily to protect the peroxyacids against decomposition which is catalyzed by heavy metals such as iron and copper. Such additional stabilizing agents are preferably present at levels of from 0.005% to 1.0% of the composition. These additional stabilizers can be any of the well-known chelating agents, but certain ones are preferred.
  • U.S. Pat. No. 3,442,937, Seenewald et al., issued May 6, 1969 discloses a chelating system comprising quinoline or a salt thereof, an alkali metal polyphosphate, and optionally, a synergistic amount of urea.
