Definitions
- the present invention relates to a process and composition for cleaning surfaces.
- a first aspect of the invention provides a packaged, aqueous or solvent-containing, nonionic cleaning composition, in a container provided with a spray jet adapted to deliver the composition to a surface in the form of a spray, characterised in that the dosage applied to the surface by each operation of the spraying apparatus falls in the range 0.15-0.5ml and the said dose is applied over an area of at least 50 cm2 when the spray jet is operated 15cm from the surface.
- a second aspect of the invention relates to a process for cleaning a hard surface which comprises the step of spraying a composition comprising a nonionic surfactant from a container provided with a spray jet, onto a surface in the form of a spray, characterised in that the dosage applied to the surface by each operation of the spraying apparatus falls in the range 0.15-0.5ml and the said dose is applied over an area of at least 50 cm2 when the spray jet is operated 15cm from the surface.
- the dosage applied to the surface by each operation of the spraying apparatus falls in the range 0.2-0.4ml: dosages of 0.25-0.35ml are particularly preferred.
- Prior-used sprays for hard-surface cleaners typically deliver upwards of 0.7ml per spraying operation, i.e. larger dosages than the sprays of the present invention. It is particularly preferred in the practice of the invention dosage is equivalent to at least 0.3ml of product delivered over an area of 80cm 2 .
- the preferred cone angles of the spray are such that 0.15-0.5ml of product is delivered over a circular region of at least 10cm diameter.
- the preferred droplet pattern on the surface is such that, for each pump cycle, a calculated 10-40 ml of product are delivered over each square meter of surface.
- Typical cone angles in embodiments of the present invention are 25-75 degrees.
- Prior-used sprays for hard-surface cleaners often deliver the product in a relatively narrow cone or jet as well as delivering significantly larger quantities of product per pump cycle.
- an important feature of the present invention is the reduced dosage and/or increased coverage as compared with the prior art.
- the preferred droplet size distribution is such that for a 10g discharge less than 350mg of product is present in droplets having a particle size of less than 7 microns. Preferably, less than 700mg of product is present in droplets having a particle size of less than 30 microns.
- the mean particle size will lie in the range 50-100 micron. It is believed that this avoids the problem of respirable particles whilst ensuring that product is delivered to the surface rather than remaining suspended in air. It is also believed that the use of this range of distribution gives good coverage of the surface and promotes the meniscus cleaning effect mentioned above.
- the droplet size range for a typical product presently on the market appears to be 30-700 microns with a peak at around 250 microns.
- compositions according to the present invention can be a simple solution or in a more complex form such as a microemulsion.
- compositions comprise 2-30% of nonionic surfactant, more preferably 3-13% nonionic.
- Anionic surfactant is optional.
- Preferred nonionic surfactants include, alkoxylated alcohols, particularly ethoxylated C8-C18 alcohols having 3-8 moles of ethylene oxide per mole of alcohol.
- Other nonionic surfactants may be employed, a plurality of said surfactants are disclosed in 'Nonionic Surfactants' by Schick (Arnold: surfactant science series, volume 1).
- the preferred concentrations of surfactant fall into the range 5-15%wt total surfactant, with levels of around 10%wt being particular preferred. These concentrations are higher than those typically used for spray compositions, but due to the lower dosage of the composition and the improved cleaning efficiency which is seen with the practice of the present invention it is possible to reduce the overall usage of surfactant. Not only does this have a direct environmental consequence, but there is an indirect benefit in that less packaging is used for the smaller containers in which the product may be packaged and less fuel in consumed in shipping the product. There is also a direct benefit to the consumer that effective cleaning can be obtained with a light yet effective delivery device.
- Hydrophobic oils are optional components of compositions according to the present invention. Suitable oils include oils which rapidly dissolve troglyceride. When oils are present preferred oils include limonene, para-cymene, dibutyl ether and butyl butyrate.
- Solvents are preferably present at levels of 3-20%wt, with levels of 5-10% being particularly preferred. Glycol ether and/or lower alcohols having 1-5 carbons are preferred as solvents although the use of short alkyl chain esters including ethyl acetate and/or pyrrolidones including N-methyl pyrrolidione, is also envisaged.
- the solvent is selected from: propylene glycol mono n-butyl ether, dipropylene glycol mono n-butyl ether, propylene glycol mono t-butyl ether, dipropylene glycol mono t-butyl ether, diethylene glycol hexyl ether, methanol, ethanol, isopropyl alcohol, ethylene glycol monobutyl ether, di-ethylene glycol monobutyl ether and mixtures thereof.
- Particularly preferred solvents are selected from the group comprising ethanol (preferably as industrial methylated spirits)., propylene glycol mono n-butyl ether (available as 'Dowanol PnB' [RTM]) and di-ethylene glycol monobutyl ether (available as 'Butyl Digol' [RTM] or 'Butyl Carbitol' [RTM]). These solvents are preferred due to cost, availability and safety factors. We have determined that this selection of solvents gives enhanced cleaning performance as regards inks and dyestuffs.
- compositions of the present invention can be alkaline, acidic or neutral, it is preferred that the composition are rather strongly alkaline, having preferred pH of >10.
- composition comprises 1-10% of an alkanolamine, with levels of 2-6%wt being particularly preferred.
- alkanolamines include: 2-amino-2-methyl-1-propanol, mono-ethanolamine and di-ethanolamine. These materials are believed to give improved cleaning on tough or aged soils.
- Suitable polymers include PVP, available in the marketplace as Polymer PVP K-90.
- Suitable levels of PVP polymer range upwards from 50ppm. Levels of 500-1500ppm are particularly preferred.
- the composition preferably has a pH of >10 and comprises, in admixture with water,: a) 3-13% nonionic surfactant b) 0-10% solvent c) 2-6% alkanolamine d) 0-5% buffer/alkali, and, e) 50-1500ppm polymer.
- compositions have a pH of >10 and comprise, in admixture with water,: a) 3-13% nonionic surfactant (most preferably, C10-EO5 nonionic surfactant) b) 5-10% solvent (most preferably, diethylene glycol mono-n-butyl ether) c) 2-6% alkanolamine (most preferably, 2-amino-2-methyl-1-propanol) d) 1-5% buffer/alkali (most preferably, sodium or potassium carbonate), and, e) 500-1000ppm polymer (preferably PVP), said composition being packaged in a container adapted to produce a spray of 0.15-0.5ml of product per spraying operation, said spray having an average drop size in the range 30-300 microns.
- nonionic surfactant most preferably, C10-EO5 nonionic surfactant
- solvent most preferably, diethylene glycol mono-n-butyl ether
- 2-6% alkanolamine most preferably, 2-amino-2-methyl-1-prop
- Cleaning performance was determined on soiled DECAMEL (RTM, ex. Formica) sheets. 0.5mg/cm 2 (based on non-volatiles) of soil were deposited on an 'A4' sized area of 'DECAMEL' test surface by spraying.
- the soil comprised 1% glycerol tripalmitate, 0.5% glycerol trioleate, 0.5% kaolin, 0.2% liquid paraffin, 0.1% palmitic acid, 0.02% carbon black in methylated spirits. The soil was allowed to age for 24 hours at room temperature prior to cleaning.
- compositions were prepared by mixing the components given in table 1 below. 10% Imbentin 91-35 (TM) C10-EO5 nonionic surfactant, 8% Butyl Digol (TM): diethylene glycol mono-n-butyl ether, 4% 2-amino-2-methyl-1-propanol, 2% Buffer/alkali (sodium carbonate) to 100% Water
- composition is a concentrate (as regards surfactant) as compared with conventional spray cleaning compositions which comprise around 4%wt surfactant, 5% solvent.
- Table 2 and figure 1 show results for six sprays using the composition described above.
- the compositions were sprayed onto unbaked soiled DECAMEL tiles prepared as described above using a variety of pumps. These pumps are identified in table 2 as P1-3 and C1-3.
- the P-series pumps were obtained from 'Perfect Valois' (TM) and the C-series pumps from 'CALMAR' (TM).
- the P-series pumps are identified by manufacturers codes as follows: P1: PZ2/290 4627, P2: PZ2/290 3020, P3: PZ2/290 2502.
- the C-series pumps are identified by manufacturers codes as follows: C1: M300 HV, C2: M300 60 degree orifice, C3: M300 30 degree orifice.
- 'DS' is the mean particle concentration averaged over a five minute period from spraying, in air, of particles per cc of a diameter less than 7 microns. Higher figures for the 'DS' correspond to lower average droplet diameters in the spray.
- cone diameter is as measured at 15cm, i.e. it is the diameter of the spray pattern at 15cm from the spray head.
- the dose is the dose applied to the tiles over the area sprayed with product. In all instances more than one cycle of the spraying apparatus was used.
- Effort is the total effort required to clean a tile completely, measured in terms of the total effort applied by a human operator in Ns..
- compositions were prepared by mixing the components given in table 5 below.
- compositions were applied to soiled DECAMEL tiles in three ways, by means of a conventional trigger spray, by means of a pipette and at low dosage accordance with the invention.
- Table 6 below, provides details of the dosage (ml), effort required to clean (Ns) and cleaning efficiency (10/[ln(effort) x dose]). Efficiency was defined without reference to the spray coverage in this instance.
