Definitions

  • the present invention is directed to improved hard surface cleaning compositions and concentrates thereof, which feature blooming when the concentrate is added to a larger volume of water.
  • Cleaning compositions are commercially important products and enjoy a wide field of utility in assisting in the removal of dirt and grime from surfaces, especially those characterized as useful with "hard surfaces".
  • One particular category of cleaning compositions are those which are classed as pine oil type cleaning compositions which typically contain a significant amount, e.g, 5%wt. of naturally derived and/or synthetically produce pine oils. Such compositions generate a milky or cloudy appearance when diluted with water in dilutions useful for cleaning applications, and are generally provided as concentrated composition which is subsequently diluted with water by an end user/consumer to form a cleaning composition therefrom. While such pine oil type cleaning compositions are commercially significant and in popular use, their use is not without attendant shortcomings.
  • pine oil in a cleaning composition are known to leave undesirable surface residues, particularly on hard surfaces.
  • pine oils require the inclusion of surfactants which are useful in solubilizing and stabilizing the pine oil.
  • surfactants which are useful in solubilizing and stabilizing the pine oil.
  • the pine oil itself are categorized as undesired volatile organic compounds ("VOC").
  • VOC undesired volatile organic compounds
  • This blooming effect (also sometimes referred to as "break" in the United Kingdom and in other countries) is an important indicia for consumer acceptance for certain products, those which traditionally use pine oil to providing the blooming effect, as well as other products which do not contain pine oil but which nonetheless exhibit this very desirable blooming behavior when added to a larger volume of water to form a cleaning and/or disinfecting composition therefrom.
  • compositions which exhibit blooming when added to a larger volume of water, but which may be selectively imparted with any of a number of different appearances and fragrances which is possible by the judicious selection of any of a number of dyes, fragrances, other colorants which may be added to the concentrate compositions to provide a desired color and a desired scent.
  • Such compositions are commercially acceptable, shelf stable concentrated cleaning and/or disinfecting compositions which exhibit blooming when diluted in water.
  • the blooming behaviour is provided although the concentrate compositions contain no pine oil or pine oil fraction (such as a te ⁇ ineol fraction) in any significant amount, other than minor amounts such a might be used in a fragrance constituent, as the compositions do not rely upon pine oil or pine oil fractions to provide their blooming characteristic when diluted with water.
  • aqueous blooming type, hard surface cleaning and/or disinfecting concentrate compositions which comprise the following essential constituents which provide a "blooming system" which is inco ⁇ orated in these compositions: a cationic quaternary ammonium surfactant; an anionic carboxylated alcohol alkoxylate surfactant; a surfactant compatibilizing agent; and, water.
  • the concentrate compositions may include further optional constituents which do not undesirably reduce or which diminish the operation ofthe blooming system described herein especially one or more further surfactants including anionic, cationic, nonionic, zwitterionic and/or amphoteric as well as mixtures thereof, one or more organic solvents such as lower alkyl alcohols, lower alkyl diols and glycol ethers, as well as one or more fragrances, coloring agents, chelating agents, germicidal compositions including those based on phenolic compounds, as well as other conventional additives.

In this way, a cleaning composition which has the physical appearance and blooming characteristic of a conventional pine oil type cleaning composition may be provided without the presence of pine oil.
  • blooming type cleaning and/or disinfecting compositions may be produced such as by including different fragrances, i.e., those characteristic of lemon, various flora, in conjunction with a desired coloring additives, i.e., green, yellow, amber, red, etc. may be added as desired.
  • a blooming type cleaning and/or disinfecting compositions may produced. "Blooming” may be described as the change ofthe water's appearance from essentially colorless and transparent to that of a milky white or milky yellowish white, cloudy appearance.
  • the lack ofthe overall amounts of pine oil typically found in prior art pine oil type cleaning concentrates, as well as the necessary compatibilizing agents required to solubilize the pine oil in such prior art cleaning concentrate provides the benefits of reduced volatile organic content of a concentrate or cleaning composition, as well as reduces the propensity of such compositions to form undesirable residues, especially pine oil residues upon cleaned surfaces.
