Description

GLASS AND CERAMIC CLEANING COMPOSITIONS
Technical Field
The present invention relates to general purpose cleaning compositions with a reduced tendency to leave streaks on cleaned surfaces, particularly glass and ceramic surfaces.
Background of the Invention
Many glass and ceramic cleaning operations employ an aqueous cleaning liquor of which a part remains as a film on a surface in the final stages of cleaning and dries by evaporation. As such an aqueous cleaning liquor dries, components which are less volatile than water remain in the film and reach relatively high concentrations. This modifies the surface tension properties of the liquor such that the film breaks up into patches of liquid. These patches roll-up into droplets. The droplets scatter light so as to cause the surface to appear less clean than desired. For the purpose of the present specification this defect in cleaning performance will be referred to as
'streaking' as the droplets are often arranged in lines, so as to give the impression of unsightly streaks on hard and shiny surfaces such as ceramic tiles or glass (whether on windows or on mirrors) .
Streaking is a particular problem when liquid, nonionic detergents and/or solvents are use in a cleaning liquor. Liquid nonionics are preferred in certain compositions so as to reduce solid deposits on cleaned surfaces and solvents are employed to improve cleaning performance. EP 66342 relates to the problem of streaking and discloses the use of rosin/maleic anhydride adducts to prevent streaking. However, the compositions of that disclosure are formulated at a pH of greater than 10 in order that the resinous material remains in solution. Formulation at this pH is undesirable for a number of reasons including harshness or even damage to the skin of users.
Known anti-streaking glass cleaning compositions typically comprise low levels of surfactants in aqueous mixtures of glycol ethers and alcohols. In use, the volatiles evaporate leaving no residue behind. It is however preferable that compositions contain low levels or be completely free of the glycol-ether and alkanol solvents. While these materials are common components of light duty cleaning compositions, it is believed that these solvents can attack painted and plastics surfaces such as window surrounds, i.e. while the effects of long term exposure of uPVC and other common window frame materials to these solvents have not been fully evaluated, doubt exists that frame materials, including the frame per se and any flexible seals will remain unaffected after repeated exposure to the glycol ether and alkanol solvents.
Other solvent systems are known in different arts.
EP 0458969 discloses cleaning compositions which comprise a polyoxyalkyene containing poly organo siloxane of 'low' molecular weight (3-8 di-organo siloxane groups). These are described with especial reference to cleaning of metal objects such as pumps and the like.
Brief Description of the Invention
We have now determined that silicone glycols of a particular molecular weight range are effective in preventing streaking of cleaning compositions which contain liquid, nonionic surfactants, particularly on glass and ceramic surfaces. This has enabled us to prepare non- streaking, solvent-free glass cleaning compositions.
Accordingly, the present invention provides a cleaning composition comprising:
(a) 0.05-10%wt of a liquid, alcohol alkoxylate, non-ionic surfactant, and,
(b) at least 5% on total surfactant of a silicone glycol having a molecular weight in the range >3, 000-40, 000.
Without wishing to limit the invention by reference to any theory of operation, it is believed that the synergistic interaction of the selected nonionic surfactant and the selected silicone glycol polymer maintains a low surface tension in the drying film and prevents roll-up of droplets to form streaks as described above. This provides the benefit of preventing streaking without requiring the use of volative glycol ethers and alcoholic solvents.
According to a second aspect of the present invention there is provided a method of cleaning a glass or ceramic surface which comprises the step of treating the surface with a composition which comprises:
(a) 0.05-10%wt of a liquid, alcohol alkoxylate, non-ionic surfactant, and,
(b) at least 5% on total surfactant of a silicone glycol having a molecular weight in the range >3, 000-40, 000. Detailed Description of the Invention
Typically, the cleaning composition comprises up to 10% of the liquid alcohol alkoxylate surfactant. Preferably, the surfactant level falls in the range 0.05-5%wt on product as low levels of nonionic are associated with particularly low levels of streaking. Surfactant levels in the range 0.05- 0.5%wt, are particularly preferred as these are sufficient to provide the cleaning effect and minimise the level of streaking. The level of surfactant should not be so low that it minimises cleaning effect. Particularly good results are obtained when the nonionic level is in the range 0.5-0.1wt%. i.e. around 0.3%wt.
Preferably, the ratio of surfactant (a) to glycol (b) is in the range 1:1-20:1. The most preferable ratios are those between 1:1-3:1 as these can be shown to provide composition which require less cleaning effort when used.
Algohpl Ethpxylate
In preferred embodiments of the invention the alcohol alkoxylate surfactant is a propoxylate or ethoxylate (or a mixed system) of the general formula:
CH3- (CH2)a- (CH2CH20)n- (CH2.CH2-CH2-0)m-OH
where a is 2-20, n is 0-20, m is 0-5 and m+n is at least one.
Particularly suitable alcohol alkoxylates are those wherein a is 8-14, n is 4-10 and m is 0-2, those wherein a is 2-6,n is 0-4, and m is 0-2. More particularly, the following alkoxylates have been found suitable: Inbentin 91-35 (RTM ex. Kolb)
Dobanol 91-5 (RTM ex. Shell)
Dobanol 91-6 (RTM ex. Shell)
Dobanol 91-8 (RTM ex. Shell)
Silicone Glvcol
Silicone glycols as typically used in the present invention are molecules of the general formula:
(CH3)3-SiO- (CH3.SiO.CH2-CH2-CH2-R)x- (CH3. SiO.CH3)y-SiO- (CH3)3
wherein -R is a polar group.
-x and y are such that the overall molecular weight of the molecule falls in the range 3000-40000.
R is preferably a polyalkoxy chain of the general formula:
R= - (CH2-CH2-0)z- (CH2-CH.CH3-0)w-R2
Wherein R2 can be alkane, such as butyl, ethyl or methyl but is preferably H and w and z are not both 0.
Preferred silicone glycols comprise polyalkyene oxide modified dimethylpolysiloxanes with a molecular weight in the range 10,000-35,000, particularly those with a molecular weight of 20,000-30,000 as we have determined that these materials are less likely to form streaks due to their low surface tension effects in drying films.
Suitable silicone glycols are available in the marketplace from the DOW Chemical Company as DC190 (TM) and DC193 (TM) . It is preferable that the silicone glycol is selected such that the compositions of the invention form 'self-healing' films, i.e. films which when scratched exhibit the properties of flowing so as to repair the scratch.
Preferred Compositions
Typical preferred formulations according to the present invention comprise:
(a) 0.05-5%wt of a liquid, alcohol alkoxylate surfactant of the general formula:
CH3- (CH2)a- (CH2CH20)n- (CH2-CH2-CH2-0)m-OH
where a is 2-14, n is 0-8, m is 0-2 and m+n is at least one, and,
(b) polyalkyene oxide modified dimethylpolysiloxane with a molecular weight in the range 20,000-30,000, having the general formula:

2) x and y are such that the overall molecular weight of the molecule falls in the range 3000-40000
3) the ratio of (a) : (b) is in the range 1:1-5:1. In order that the present invention may be further understood it will be described hereafter by way of examples .

The extent of streaking was determined through the following test. Solutions were spread onto clean microscope slides, which had previously been washed in water and rinsed with acetone before drying at ambient temperature. The surface of the slide was observed under reflected light using a high resolution microscope equipped with interference contrast lighting (Leitz Aristomat) which allows the easy detection of residual surfactant and its classification as a streaky deposit of droplets (s) or a non-streaky film (f) .
The self healing properties of the film were determined by scratching the film with the point of a metal seeker and observing the results using the microscope. Films which were unstable to scratching are indicated 'F*' in the table. For examples 8-12 the concentrated compositions were spread very thinly using paper tissue. Comparative examples are marked with an asterisk.

The addition of silicone digol to these compositions prevents streaking, (see examples 4-6, 11-16 and 19-20) . However the streaking is not prevented if the ratio of the digol to the nonionic is too low (see comparative examples 9-10) or the molecular weight of the digol is too low (see comparative examples 2-3 and 7) .
Bearing all of the above in mind, it can be seen that of the examples only those compositions which have the selected ratio of silicone digol to nonionic surfactant exhibit the formation of self-healing films on the surfaces.
