Definitions

  • This invention relates to liquid detergent compositions.
  • it relates to aqueous detergent compositions suitable for use as general purpose household cleaning compositions.
  • Powdered cleaning compositions consist mainly of builder or buffering salts such as phosphates, carbonates, silicates etc., and although such compositions may display good inorganic soil removal, they are generally deficient in cleaning ability on organic soils such as the grease/fatty/oily soils typically found in the domestic environment.
  • Liquid cleaning compositions on the other hand, have the great advantage that they can be applied to hard surfaces in neat or concentrated form so that a relatively high level of surfactant material is delivered directly to the soil. Moreover, it is a rather more straightforward task to incorporate high concentrations of anionic or nonionic surfactant in a liquid rather than a granular composition. For both these reasons, therefore, liquid cleaning compositions have the potential to provide superior grease and oily soil removal over powdered cleaning compositions.
  • liquid cleaning compositions still suffer a number of drawbacks which can limit their consumer acceptability.
  • they generally contain little or no detergency builder salts and consequently they tend to have poor cleaning performance on particulate soil and also lack "robustness" under varying water hardness levels.
  • they can suffer problems of product form, in particular, inhomogeneity, lack of clarity, or inadequate viscosity characteristics for consumer use.
  • the higher in-product and in-use surfactant concentration necessary for improved grease handling raises problems of extensive suds formation requiring frequent rinsing and wiping on behalf of the consumer.
  • oversudsing may be controlled to some extent by incorporating a suds- regulating material such as hydrophobic silica and/or silicone or soap, this in itself can raise problems of poor product stability and homogeneity and also problems associated with deposition of insoluble particulate or soap residues on the items or surfaces being cleaned, leading to filming, streaking and spotting.
  • a suds- regulating material such as hydrophobic silica and/or silicone or soap
  • terpenes herein specified are valuable in regulating the sudsing behaviour of the instant compositions in both hard and soft water and under both diluted and neat or concentrated usage, while terpenes of the terpene alcohol class are also valuable for providing effective control of product viscosity characteristics.
  • Terpenes are, of course, well-known components of perfume compositions and are often incorporated into detergent compositions at low levels via the perfume. Certain terpenes have also been included in detergent compositions at higher levels; for instance, DE-A-2, 113,732 discloses the use of aliphatic and alicyclic terpenes as anti-microbial agents in washing compositions, while GB-A-1,308,190 teaches the use of dipentene in a thixotropic liquid detergent suspension base composition.
  • DE-A-2,709,690 teaches the use of pine oil (a mixture mainly of terpene alcohols) in liquid hard surface cleaning compositions. There has apparently been no disclosure, however, of the combined use of a terpene cleaning agent with a polar solvent of low-water solubility.
  • the present invention thus provides liquid detergent compositions which are stable homogeneous fluent liquids having excellent suds control across the range of usage and water hardness conditions and which provide excellent shine performance together with improved cleaning characteristics both on greasy/oily soils and on inorganic particulate soils with little tendency to cause filming or streaking on washed surfaces.
  • a liquid detergent composition comprising a water base together with:
  • Preferred terpenes are mono- and bicyclic monoterpenes, especially those of the hydrocarbon class, which can be selected from terpinenes, terpinolenes, limonenes and pinenes. Highly preferred materials of this type include d-limonene, dipentene, a-pinene, ,B-pinene and the mixture of terpene hydrocarbons obtained from the essence of oranges (eg. cold-pressed orange terpenes and orange terpene oil phase ex fruitjuice).
  • Terpene alcohols, aldehydes and ketones can also be used, however, the alcohols, in particular, providing valuable but unexpected improvements in viscosity regulation when incorporated in the compositions of the invention at a level, preferably, of from 1% to 3%, more preferably from 1.5% to 2.5%.
  • the terpene is used in combination with a polar solvent (i.e. containing at least one hydrophilic group) having a solubility in water of from 0.2% to 10% by weight (g/100 g solution), preferably from 0.5% to 6% by weight, for example benzyl alcohol.
  • compositions of the invention also preferably contain from 0.005% to 2%, more preferably from 0.05% to 0.7% of an alkali metal, ammonium or alkanolammonium soap of a C 13 -C 24 , especially C 13 -C 18 , fatty acid.
  • the fatty acid is fully saturated, for example, by hydrogenation of naturally occurring fatty acids. Addition of the soap, particularly to compositions containing terpene hydrocarbons, is found to provide significant synergistic enhancement in the suds-suppression effectiveness of the system.
  • a calcium sequestrant is also desirable in the present compositions, providing not only cleaning advantages on particulate soil, but also, surprisingly, advantages in terms of product homogeneity and stability.
  • the sequestrant component is a water-soluble inorganic or organic polyanionic sequestrant having a calcium ion stability constant at 25°C of at least 2,0, preferably at least 3.0, the weight ratio of surfactant:sequestrant preferably lying in the range from 5:1 to 1:3, especially 3:1 to 1:1.
  • the sequestrant has an anion valence of at least 3 and is incorporated at a level of from 0.5% to 13% by weight.
  • the composition itself preferably has a pH in 1 % aqueous solution of at least 8.0.
  • the sequestrant can be selected from the water-soluble salts of polyphosphates, polycarboxylates, aminopolycarboxylates, polyphosphonates and amino polyphosphonates and added at a level in the range from 1 to 9%, especially 2 to 8%, more especially 3 to 7% by weight of the composition. Adjustment of the sequestrant level and surfactant:sequestrant ratio within the above specified ranges is important for providing compositions of optimum stability.
  • a notable feature of the instant compositions is the suds-suppression effectiveness of the terpenes in liquid compositions based on ampholytic or zwitterionic surfactants.
  • ampholytic or zwitterionic surfactants are notoriously difficult to control the sudsing behaviour of these surfactants in a cost-effective manner using conventional suppression agents such as soaps, waxes etc.
  • the terpenes are thus particularly valuable in this respect.
  • anionic, nonionic, zwitterionic and amphoteric surfactants can be used in the present compositions.
  • a typical listing of the classes and species of these surfactants is given in US-A-3,663,961.

  • the paraffin sulfonates are highly preferred.

  • alkane chains of the foregoing non-soap anionic surfactants can be derived from natural sources such as coconut oil or tallow, or can be made synthetically as for example using the Ziegler or Oxo processes.

  • Suitable nonionic surfactants include alkoxylated nonionic surfactants and also those of a semi-polar character.
