Definitions

  • the present invention relates to improvements relating to cleaning compositions and in particular to improvements relating to cleaning compositions comprising surfactants and solvents.
  • compositions for use in cleaning of household and industrial hard surfaces comprise solvent components, in addition to surfactants. These solvents are generally intended to improve cleaning performance by assisting in the removal of greasy or waxy soils. The advantages associated with the presence of solvents in such compositions are particularly marked at low surfactant levels, such as are found in compositions for use on highly reflective surfaces upon which high levels of surfactant residues cannot be tolerated.
  • solvent components are immiscible with water or have a relatively low level of miscibility above which they form emulsions and therefore those compositions which comprise levels of solvent above the miscibility limit either need to be shaken vigorously prior to use or the solvent needs to be present as a stable emulsion.

  • the cleaning composition further comprises an anionic surfactant. It is envisaggd that a broad range of anionic surfactants can be used in the embodiments of the present invention, some of which are listed below.

  • the anionic detergents are the magnesium salts of primary alcohol sulphates. These are believed to be more readily biodegradable than other surfactants and are available in commercial quantities from renewable resources.
  • Primary alcohol sulphates are mixture of materials of the general formulation:
  • R is a C 8 to C 18 primary alkyl group and X is a solubilising cation.

  • compositions are formed when the surfactant system consists solely of the magnesium salt of an anionic surfactant, particularly the magnesium salt of a primary alcohol sulphate.
  • compositions according to the present invention therefore comprise:
  • magnesium salt of an anionic surfactant preferably the magnesium salt of primary alcohol sulphate

Provided that these components are present at sufficiently low levels they do not interfere with the function of the invention.
  • compositions directly onto a soiled surface rather than cleaning the surface with a cloth or sponge dampened with the compositions. It is believed that the evaporation of one of the components of the cleaning composition is critical to the use of the inventive compositions in practice and that evaporation proceeds more effectively during the spraying operation and from a surface than from a cloth.
  • a further aspect of the present invention comprises a process including the steps of:
  • a yet further aspect of the present invention relates to a homogeneneous composition
  • a homogeneneous composition comprising solvent and surfactant which decomposes into a solvent-water emulsion as a portion of the solvent evaporates, packaged in a container adapted to produce a spray.
  • Figure 1 is a graph showing the cleaning efficiency of commercial n-butoxy propan-2-ol (DOWANOL PnB) with concentration, and,
  • Figure 2 illustrates the cleaning efficiency of the compositions prepared as examples in graphical form.

  • PAS Magnesium salt of C 10 -C 18 primary alcohol sulphate: anionic surfactant.
  • NON Dobanol 91-350FA [RTM]: nonionic surfactant. From figure 1 it can be seen that the cleaning efficiency of PnB-based compositions is particularly dependent on PnB concentration in the range between 5 and 7 wt% concentration on product. To obtain these results 1.0 ml of each neat sample was applied with a sponge on to soiled Decamel [RTM] tiles (soiled with 80/20 fat/particulate soil at 0.25mg/cm.cm) and wiped using 10 reciprocal Sheen rubbing cycles (76 g/cm.cm applied load) . The percentage cleaning efficiency was calculated from reflectance measurements.
  • Single phase compositions were formed by simple mixing of the components according to the formulations given in Table 1, the balance of the formulation being water.
  • Example 1 is a control experiment to illustrate the base-line cleaning effect of a single phase system containing PnB.

  • compositions of example 3 are clear, homogeneous systems which, in use, lose the alcoholic solvent to the ambient and reach a composition at which there is just sufficient alcohol present to solubilise all of the PnB present. At this composition, further loss of volatile solvent results in phase separation of the PnB.

  • each sample was applied to a black ceramic tile and spread over the surface with a clean, dry cloth to form a thin film which was allowed to evaporate to dryness.
  • the film was observed closely by eye to determine the formation of any emulsion (indicated by a transformation from a transparent film to an opaque film) .
  • the only sample observed to form an emulsion was that of example 13, an embodiment of the invention.
  • Examples 14-27 illustrate the effect of the choice of surfactant on product performance.
  • PnB are normally phase separated into an aqueous phase and an excess solvent phase. However, in the presence of the co- solvent the formulations of examples 16-19 exhibited a single phase.
  • Examples 14 and 15 are control experiments to illustrate the cleaning effect of a single phase system containing PnB, below the maximum miscibility.
  • the cleaning performance of these compositions appears slightly better in the presence of the nonionic surfactant (comparative example 14) than the anionic surfactant (comparative example 15) .
  • This is in agreement with the results noted in respect of comparative example 1 mentioned above.
  • embodiments 17 and 19 that the addition of IPA or IMS as co-solvents in the presence of a slightly increased level of PnB improves the cleaning performance greatly. This is in agreement with the results discussed above comparing examples 1 and 3 as mentioned above.
  • Examples 16 and 18 are examples using a nonionic surfactant. Although these compositions had a cleaning performance approaching that of embodiments 17 and 19, the compositions became cloudy on storage. It is to be noted that the anionic surfactant in compositions according to the preferred embodiment of the present invention exhibits better cleaning performance than the nonionic surfactant (compare examples 16 and 17) .
  • Comparative examples 20-27 shows that combinations of solvent which fall outside of the scope of the present invention did not have effective cleaning performance. In these comparative compositions no emulsion was formed on the evaporation of the volatile solvent component.

Abstract

L'invention concerne une composition homogène, aqueuse de nettoyage comprenant un tensioactif et un solvant, et elle est caractérisée en ce qu'ils forment une émusion de solvant et d'eau lors de l'évaporation d'au moins une partie du solvant. Dans ce type de systèmes le système de solvants est sélectionné de manière qu'il comprend: un premier constituant solvant en une quantité telle qu'il représente un niveau supérieur à la limite de miscibilité de ce constituant avec l'eau, et, un second constituant solvant suffisamment volatile pour que, en utilisation, il s'évapore de la composition pour laisser un mélange du premier constituant solvant et d'eau, ledit second constituant solvant représentant un niveau tel que le premier constituant solvant est solubilisé dans la composition. Le fait d'utiliser le second solvant comme auxiliaire dans la solution du premier solvant permet d'obtenir des compositions claires, stables, isotropes. Lors de l'utilisation, le second constituant solvant volatile s'évapore de la composition dans son ensemble et le premier constituant solvant restant ainsi que la phase aqueuse se séparent, formant ainsi une émulsion, de manière que l'action de nettoyage du premier constituant solvant est renforcée. L'émulsion formée comporte une phase dispersée grossière. La composition de l'invention présente les avantages d'un produit stable sans émulsion du point de vue du stockage, du dosage et de la production, elle utilise un niveau relativement faible de solvants et elle offre les caractéristiques avantageuses de nettoyage d'un système à solvants libres.
