Definitions
- the present invention relates to hard surface cleaning compositions which contain a UV absorbing agent.
- EP697481 (CIBA-GEIGY, 1995) concerns textile treatment with a composition comprising a UV absorbing compound (UV filter), emulsifying agent, water and polysiloxane (i.e. silicone) in an otherwise aqueous textile treatment composition which comprises: a) a non-reactive UV filter b) an emulsifying or dispersing agent for the UV filter c) water d) optionally, a polysiloxane based product.
- UV filter UV absorbing compound
- emulsifying agent i.e. silicone
- US 5,767,054 describes surface disinfection and cleaning compositions comprising as essential ingredients a biocidal agent, a solvent and a perfluoroalkanoic acid tenside. These compositions are intended for medical instruments and surfaces. They may also contain a UV filter, especially when the compositions are used to clean sensitive synthetic leather. The fluoroaliphatic tenside is said to leave a thin film on the cleaned surface. However, such tensides are expensive and not suitable for normal "household use" hard surface cleaning compositions.
- Normal hard surface cleaning compositions comprising the usual anionic and/or nonionic detergent surfactants, are not normally expected to leave a useful protective layer of any kind on a cleaned surface due to the tendency of these compositions to remove an agent from the surface rather than to deposit it.
- UVB range 280-320nm
- UVA range 280-320nm
- UVB filters UVA filters
- UV filter compounds which absorb more light in the UVA than in the UVB range are better suited for protection of many hard surfaces against the deleterious effects of sunlight than UV filter compounds which have most of their absorbtion in the UVB range (UVB filters) . This holds particularly for indoor surfaces.
- a hard-surface cleaning composition comprising:
- a second aspect of the present invention relates to a method of reducing UV damage to hard surfaces which comprises the step of treating the surface with a cleaning composition as described above.
- UVA filters are defined as set out below:
- the absorbtion spectra of UV filter compounds were measured over the entire UVA and UVB ranges.
- the percentage of absorbance in the UVA range can be calculated using the formula:
- UVA x 100% relative UVA absorbance Spectral area (UVA+UVB)
- UVA filters are defined as UV filter compounds for which the relative UVA absorbance is at least 50%.
- Suitable compounds are among the benzotriazol derivatives e.g. those marketed by Ciba-Geigy as "Tinuvin” such as: Tinuvin 328 (2- (2H-benzotriazol-2-yl) -4 , 6-ditert . pentyl- phenol, having a relative UVA absorbance of 59%), Tinuvin 234 (2- (2H-benzotriazol-2-yl) -4 , 6-bis ( 1-methyl-l- phenylethyl) phenol) and Tinuvin 327 (2, 4-ditert .
- Tinuvin 328 (2- (2H-benzotriazol-2-yl) -4 , 6-ditert . pentyl- phenol, having a relative UVA absorbance of 59%)
- Tinuvin 234 (2- (2H-benzotriazol-2-yl) -4 , 6-bis ( 1-methyl-l- phenylethyl) phenol
- Tinuvin 327 2, 4-
- Uvasorb SV (2- (2H-benzotriazol-2-yl) -4- methylphenol)
- Uvasorb S26 (2- ( 3 ' -tert-butyl-2 ' -hydroxy- 5 ' -methylphenyl) -5-chlorobenzotriazole)
- Uvinul D50 TM bis (2 , 4-d ⁇ hydroxy-phenyl) methanone, having a relative UVA absorbance of 66%) marketed by BASF.
- the benzotriazol derivatives are particularly effective and Tinuvin 328 is especially preferred because of its stability.
- laundry detergent compositions comprise so called optical whiteners or brighteners, i.e. fluorescent compounds which absorb UV light and re-emit part of this as visible, particularly blue light.
- optical whiteners or brighteners i.e. fluorescent compounds which absorb UV light and re-emit part of this as visible, particularly blue light.
- Such compounds have no use in the hard surface cleaning compositions of the present invention and are therefore not comprised in the term ⁇ UV filter' .
- Suitable levels of UV filters are from 0.01%wt upwards, preferably at least 0.05%, more preferably at least 0.08%. Higher amounts than 2%wt rarely serve a useful purpose and the amounts are preferably at most 1%, more preferably at most 0.5%.
- compositions of the invention are liquid, more preferably aqueous liquids and are preferably not macroscopic emulsions.
- the pH of the composition can fall in the range 1.0- 12, it is preferable that the pH of the composition is not below 2.0, more preferably not below 3.0. Above pH 8.5 the benefit of some UV filters falls off while other UV filters may successivefully be used up to pH 12. Below pH 3.0 damage to some hard surfaces may occur, especially to enamel surfaces.
- the preferred pH is from around 3.0 to 11 for compositions according to the present invention, more preferred 3.5-10.
- a base such as sodium hydroxide sodium carbonate, ammonia or an alkanolamine and/or an acid such as citric acid or other di/tricarboxylic acids are generally used to bring the pH to the desired level.
- compositions of the present invention comprise at least one detergent surfactant.
- surfactants may be chosen from a wide range of anionic, nonionic, cationic, amphoteric or zwitterionic surfactants well known in the art.
- the overall level of surfactant in the compositions of the invention is 0.1-
- compositions according to the invention comprise at least a nonionic surfactant in an amount of 20% by weight or more, more preferably 30% or more, of the total amount of surfactant in the composition.
- Suitable anionic surfactants are e.g. water-soluble salts, particularly alkali metal, alkaline earth metal and ammonium salts, of organic sulphate esters and sulphonic acids having in the molecular structure a C8-C22 alkyl radical or a C10-
- anionic surfactants are water soluble salts of: - long chain (i.e. 8-22 C-atom) alcohol sulphates
- PAS especially those obtained by sulphating the fatty alcohols produced by reducing the glycerides of tallow or coconut oil; alkyl benzene sulphonates, such as those in which the alkyl group contains from 6 to 18 carbon atoms; secondary alkanesulphonates .
- nonionic surfactants are very useful surfactants for use in the compositions according to the examples. They are preferably used in an amount of 0.1-
- nonionic surfactants can be broadly described as compounds produced by the condensation of alkylene oxide groups which are hydrophilic in nature, with an organic hydrophobic compound which may be aliphatic or alkylaromatic in nature.
- the length of the hydrophilic or polyoxyalkylene radical which is attached to any particular hydrophobic group can be readily adjusted to yield a water-soluble or water dispersible compound having the desired balance between hydrophilic and hydrophobic elements.
- Particular examples include: the condensation products of straight or branched chain aliphatic alcohols having 8-22 C-atoms with ethylene oxide, having 2-15 moles of ethylene oxide per mole of alcohol; condensates of alkylphenols, whose alkyl group have 6-16 C- atoms, with 2-25 moles of ethylene oxide per mole of alkylphenol; condensates of ethylene oxide with the reaction product of ethylenediamine and propylene oxide, the condensates containing 40-80% of ethylenoxy groups by weight and having a molecular weight of from 5,000 to 11,000.
- nonionic surfactants are: tertiary amine oxides of general structure RRRNO, where one R is a C8-C22 alkyl group (preferably C8-C18) and the other Rs are each C1-C5 (preferably C1-C3) alkyl or hydroxyalkyl groups, for instance dimethyldodecylamine oxide; tertiary phosphine oxides of structure RRRP0, where one R is a C8-C22 alkyl group (preferably C8-C18) and the other Rs are each C1-C5 (preferably C1-C3) alkyl or hydroxyalkyl groups, for instance dimethyl-dodecylphosphine oxide; dialkyl sulphoxides of structure RRS0 where one R is a C10-
- C18 alkyl group and the other is methyl or ethyl, for instance methyltetradecyl sulphoxide; fatty acid alkylolamides; alkylene oxide condensates of fatty acid alkylolamides; alkyl mercaptans; alkyl polyglycosides .
- alkoxylated alcohols more particularly ethoxylated alcohols are most preferred as surfactants.
- Cationic surfactants can be included in the compositions of the invention.
- the cationic surfactants are quaternary ammonium salts of the general formula R ⁇ R 2 R 3 RN + X " , wherein all of the radicals are hydrocarbons with or without hydroxy substitution, at least one of the radicals R1-R4 is a C6-C22 alkyl, alkaryl or hydroxyalkyl, at least one of the radicals R1-R4 is a C1-C4 alkyl or hydroxy alkyl and X is a monovalent anion equivalent.
- Rl and R2 are the same or different C1-C4 alkyl or hydroxy alkyl
- R3 is a C6-C22 alkyl, alkaryl or hydroxyalkyl

- Preferred levels of cationic surfactant are around 0.2-3%wt.
- compositions can further comprise one or more amphoteric surfactants, preferably betaines, or other surfactants such as amine-oxide and alkyl-amino-glycinates .
- amphoteric surfactants preferably betaines, or other surfactants such as amine-oxide and alkyl-amino-glycinates .
- Betaines are preferred for reasons of cost, low toxicity and wide availability.
- Polymers :
- compositions according to present invention comprise a water soluble polymer.
- a water soluble polymer may be included for obtaining antiresoiling benefits on the surfaces treated with the compositions. Also, such polymers help in retaining the UV filter on the surface.
- the polymers may be cationic, nonionic or anionic.
- Anionic polymers are particularly preferred, especially those having an average molecular weight of less than 1,000,000 since it is believed that as the molecular weight increases above this limit the cleaning benefit of the polymer is reduced
- these anionic polymers are polymers bearing carboxylate functional groups, although the use of other anionic polymers is possible.
- anionic polymers are those which under proper pH conditions are capable of carrying a negative charge.

- the level of polymer is at least 0.05% at which level the anti-resoiling benefits become particularly significant. Even more preferably at least 0.1% of polymer is present, most preferably at least 0.2%. Higher levels of polymer than 3% or even 2% do not give significant further cleaning advantages taking common dilution factors into account, while increasing the cost of compositions. However, for very concentrated products which are strongly diluted prior to use, the initial polymer level can be as high as 5%.
- compositions according to the invention do contain an anionic polymer then anionic surfactants are preferably only present in relatively small amounts i.e. below 2% of the composition, preferably below 1%.

- the level of insect repellent required will vary with the nature of the material used. For essential oils and terpenoids, preferred levels are 0.1-5% on product .
- compositions according to the invention can contain other minor ingredients which are not essential, but aid in their cleaning performance and in maintaining the stability of the product .
- Hydrotropes are useful optional components.
- the use of hydrotropes enables the cloud point of the compositions to be raised without requiring the addition of anionic surfactants.
- Suitable hydrotropes include, alkali metal toluene sulphonates, alkali metal xylene and cumene sulphonates, alkalimetal short chain aliphatic sulphonates, urea, polyglycols, >20EO ethoxylated alcohols, short chain, preferably C2-C5 alcohols and glycols.
- Preferred amongst these hydrotropes are the sulphonates, particularly the cumene, xylene and toluene sulphonates.
- the aromatic sulphonate hydrotropes are not considered anionics surfactants.
- Typical levels of hydrotrope range from 0-5% for the sulphonates. Correspondingly higher levels of urea and alcohols are required. Hydrotropes are not always required for normal concentration, such as sprayable products, but may be useful if lower EO or longer alkyl ethoxylates are used or the cloud point needs to be raised considerably. Typically, the cloud point of the final composition should preferably be 15
- the sodium cumene sulphonate (SCS) is the most preferred hydrotrope.
- a further optional ingredient for compositions according to the invention may be a suds regulating material, which can be employed in compositions according to the invention which have a tendency to produce excessive suds in use.
- a suds regulating material is soap.
- Soaps are salts of fatty acids and include alkali metal soaps such as the sodium, potassium, ammonium and alkanol-ammonium salts of C8- C24 fatty acids, and preferably C10-C20. Particularly useful are the sodium and potassium and mono-, di- and tri- ethanolamine salts of the mixtures of fatty acids derived from well known vegetable oils.
- the amount of soap generally is at least 0.005%, preferably 0.5% - 2% by weight of the composition.
- suds regulating materials are organic solvents, hydrophobic silicas, silicone oils, hydrocarbons, and mixed EO/PO nonionic surfactants.
- Bleaching compounds generally serve no useful purpose in cleaning compositions of the present invention and will therefore normally be absent.
- compositions according to the invention are preferably liquid, more specifically aqueous solutions of the active ingredients. They may be concentrated, such as to be diluted by the consumer before use. They may also be more diluted ("normal" concentration) which are also suitable for direct application on the surface. In the latter case the total amount of surfactant in the composition is preferably at most 8%, more preferably at most 7%.
- Such compositions are very suitable for delivery to the surface as a spray or foam using a suitable dispensing system such as a trigger spray head or other devices known in the art.
- compositions according to the invention are intended for cleaning hard surfaces and therefore the invention also provides a process for cleaning hard surfaces and at simultaneously protecting it against UVA induced damage comprising applying to the surface a cleaning composition as described above, either as a dilute aqueous solution or neat.

- Tinuvin 328 and Uvinul M40 were predissolved (2.5%) in diethylene glycol n-butyl ether, which solutions were thereafter dispersed in 5% Imbentin 91- 3.5 solution.
- the UV filter solutions were diluted with 5% Imbentin 91-3.5 solution to give spectra with maximum absorbances below 2.
- the solution spectra were measured on a Perkin Elmer Lambda 40 Bio UV/visible spectrophotometer . 1cm pathlength UV compatible cuvettes were used. The wavelength range scanned was 500nm-250nm. Measurements were made at 20°C.
- the UV filters used in the above cleaning compositions were Uvinul D50, Uvinul M40 and Tinuvin 328.
- Uvinul D50 was dispersed as such in the cleaning compositions.
- Uvinul M40 was first dissolved in diethylene glycol n-butyl ether (10% wt solution) which solution was thereafter incorporated at 1% in the cleaning composition.

- TM covered with MYLAR 1000D film (Du Pont de Nemours) .
- L*a*b* The colour of the samples before and after exposure was measured using a Dr Lange Colour Meter, using the CIELab colour space, L*a*b*.
- L* measures light-dark. The larger L*, the lighter, so a negative dL* signifies darkening.
- a* measures red-green, positive a* are red, negative are green.
- b* measures blue-yellow, positive b* are yellow, negative are blue.
- b* was positive, so a positive db* indicates an increase in yellowness.
- pine and beech woods give rapid responses, in terms of colour change, in simulated sunlight, and therefore can act as a rapid test of sunscreen efficacy.
- test pieces were treated with cleaning composition 1 containing either Tinuvin 328, Uvinul D50 or Uvinul M40. According to the definition given herein the former two are UVA filters and the latter is a UVB filter.
