Definitions

  • the present invention relates to cleaning compositions and, more particularly, to a new class of cleaning compositions that treat stains and oily dirt on colored fabrics, textiles, and hard surfaces.
  • cleaning compositions particularly commercial laundry detergents and soaps available in the marketplace, function as substances that physically remove dirt, soil, and stains from the textile surfaces being cleaned.
  • These commercial detergents and soaps are surface active materials containing surfactants and concentrate at the textile surfaces where the dirt resides.
  • the cleaning surfactants are in equilibrium with like surfactants in the wash cleaning liquid. Simply stated, these surfactants physically incorporate (dissolve) the dirt, oil, or stains in their micelles and then transport them away from the textile surfaces and into the bulk of the cleaning liquid.
  • hypochlorites Typical commercial bleaching agents contain hypochlorites .
  • a hypochlorite is a chemically strong oxidizing agent generally preferred to weaker hydrogen peroxide. Hypochlorite is effective as a stain-removing bleach, but has a major drawback, viz., it indiscriminately bleaches (i.e., discolors) many colored materials, attacking and altering the fabric color. Thus, in cleaning laundry textiles, commercial hypochlorite bleaches can only be used for white clothing. As a result, one has to resort to the chemically less aggressive oxygen based bleaches (e.g., peroxides and peroxy acids) when one wants to clean stained or oil-soiled colored textiles.
  • oxygen based bleaches e.g., peroxides and peroxy acids
  • hypochlorite bleaching of white textiles The results are rarely as satisfying as those obtained from hypochlorite bleaching of white textiles. It should also be noted that the aggressive bleaching nature of hypochlorite weakens the fabric of clothing. Thus, after a number of washings, the treated materials are usually less durable.
  • the present invention offers a powerful new approach to cleaning in general and, in particular, to cleaning of colored textiles without harming the fabric. It combines the chemical bleaching of hydrogen peroxide at a higher pH level and the uniquely powerful oil-solubilizing terpenes to give a vastly superior and efficacious product.
  • the new laundry compositions of this invention comprise a source of hydrogen peroxide and hydrophobic solvents and/or surfactants in a dry formulation.
  • hydrophobic surfactants usually, but not limited to, nonionic surfactants
  • hydrophobic solvents One specific and very effective class of hydrophobic solvents is the terpene hydrocarbons and, more specifically, d-limonene.
  • the new formulations of this invention are unique because they run counter to current wisdom. Terpene hydrocarbons are never suggested for use alongside hydrogen peroxide. From a chemical composition point of view, terpenes, specifically d- limonene, would not be expected to be stable for extended periods of time in the presence of hydrogen peroxide. To stabilize a composition combining terpene hydrocarbons and hydrogen peroxide and enlist their combined cleaning qualities, this invention uses a ry" formulation. The dry formulation is also configured to provide a pH that maximizes the bleaching power of the hydrogen peroxide.
  • compositions are disclosed suggesting the use of the combination of hydrogen peroxide and terpenes.
  • the description relates to a product incorporating hydrogen peroxide and the hydrophobic terpenes in a liquid composition. The function of this liquid composition is not for the laundering of textiles and fabrics .
  • liquid composition is not formulated for high pH levels exceeding 9.5, which enhance the bleaching effects of the hydrogen peroxide.
  • These patents teach away from the present invention by using very low pH levels. These low pH levels make the liquid combination of terpenes and hydrogen peroxide stable in solution.
  • laundry cleaning compositions combining the chemical cleaning (bleaching) ability of hydrogen peroxide with the physical cleaning ability of hydrophobic solvents, like the terpene hydrocarbons, specifically d-limonene.
  • the compositions are dry formulated at a pH level enhancing the capability of the hydrogen peroxide to bleach the fabrics and textiles to which they are applied.
  • the enhancing pH level exceeds approximately 9.5.
  • the invention features new and unique compositions providing improved cleaning efficacy for all types and colors of fabrics, as well as extending the range and types of stains and dirt commonly treated by present day commercial laundry compositions.
  • compositions of this invention incorporate both hydrogen peroxide and hydrophobic solvents or surfactants like d-limonene in a dry formulation where the pH level exceeds approximately 9.0 in order to maximize the bleaching power of hydrogen peroxide .
  • liquid formulations containing peroxide A major disadvantage of liquid formulations containing peroxide is their instability. This is particularly true of the liquid composition when hydrogen peroxide is mixed with terpenes. Such liquid combination can only be formulated at a low pH, i.e., less than 8. However, the effectiveness of hydrogen peroxide as a bleaching agent increases dramatically as the pH level rises above 9.5 to 10.
  • the improved efficacy as a bleaching agent in this elevated pH range is believed to be due to the fact that at this higher pH level there is broader based bleaching.
  • the hydrogen peroxide can bleach not only as an oxidizing/reducing agent, but also as a powerful nucleophilic agent via the hydroperoxide anion. This nucleophilic anion has been found in appreciable quantities at pH levels above 9.5 to 10.
  • the invention utilizes soda ash to boost the pH level of the compositions.
  • One of the major advantages of the formulations of the present invention is their ability to be directly applied in paste form to fabrics such as clothes and carpets .
  • the dry formulations can be mixed with a little water to form this paste, and the paste can be gently applied to the fabric surface.
  • the high pH level provides excellent bleaching action to stains. Additionally, fatty acid-based stains, which constitute a common source of oily stains in laundry textiles, are more readily removed from surfaces at pH levels above 9.
  • formulations described herein are primarily directed to laundry cleaning, these compounds have additional use as cleaners for hard surfaces such as tile, grout, ceramics, porcelain, plastics, fiberglass, carpets, upholstery, concrete, wood decks, etc.
  • compositions containing an encapsulated hydrogen peroxide source are formulations containing an encapsulated hydrogen peroxide source.
  • the encapsulation offers greater stability both for the peroxide and the terpene.
  • Another advantage of compositions disclosed herein is their inherently safer use, transport, and storage compared to their liquid counterparts.
  • compositions of this invention are the effectiveness of the terpenes at temperatures lower than heretofore reported for other hydrophobic solvents.
  • Another aspect of this invention is improved stain removal on a broad range of stain types, including oil and grease, fruit and vegetable, enzymatic, such as grass and blood, and particulate-based gray and mud/clay stains.
  • Amphoteric Surfactants 0.5 - 5.0 Sodium Perborate or Percarbonate (each as a monohydrate or a tetrahydrate) 8 - 60
  • the terpenes used in this invention can be selected from a group consisting of: d-limonine, 1-limonine, dipentene, ⁇ -pinene, ⁇ -pinene, and combinations thereof.

Abstract

L'invention concerne des compositions de nettoyage fonctionnant d'une manière particulière. Ces nouvelles compositions présentent une efficacité améliorée pour le nettoyage de tous les types de surfaces. Dans les applications de lessives textiles, ces composition présentent en outre un pouvoir nettoyant élevé pour tous les types et toutes les couleurs de textiles, et permettent en outre d'élargir l'éventail des taches et les types de taches et de salissures pouvant être traités habituellement au moyen des compositions de lessive commerciales existantes.
