Definitions
- the present invention relates to a cleaning composition for hard surfaces that is useful against tough soil especially greasy soil.
- the cleaning composition comprises specific alkyl quaternary ammonium cationic surfactants that are very effective against toughened soil on hard surfaces.
- a particular type of stain which is very hard to remove from a hard surface is an aged, dried or baked stain which is frequently the residues of cooking oils and greases.
- Oil stains and other greases are usually easy to remove when they are not hardened and/or dry, however when they are dried and hardened, e.g. by aging or baking, the stains are particularly difficult to remove.
- WO97/44427 discloses an alkaline aqueous hard surface cleaning composition which exhibits good cleaning efficacy against hardened, dried or baked greasy soil deposits.
- the composition comprises non-ionic surfactants based on amine oxides, chelating agents, caustic and a glycol ether solvent system comprising one glycol ether or glycol ether acetate solvent having a solubility in water of not more than 20 wt%, and a second glycol ether or glycol ether acetate having a solubility of approximately 100 wt%, wherein the ratio of the former and latter is from 0.5:1 to 1.5:1 and other optional ingredients.
- the compositions comprise no anionic or cationic surfactants.
- compositions require many ingredients among which are at least two different glycol ether compounds. Furthermore it was found that the addition of anionic or cationic surfactants to these compositions decrease the cleaning properties.
- Another object of the invention is a cleaning composition that requires less effort in the cleaning task.
- Another object of the invention is the provision of a cleaning composition that has a simple formulation, does not require many ingredients and is easy to formulate.
- a further object of the invention is the provision of a cleaning composition that does not require a glycol ether system.
- Yet another object of the invention is the provision of a cleaning composition that requires only small amounts of non-ionic surfactants or even no non-ionic surfactants.
- a cleaning composition comprising 0.1-10 wt% of a quaternary ammonium compound of the formula R1R2R3R4N+ wherein R1 is an C10-C16 alkyl, R2, R3, R4 are each H or C1-C3 alkyl or substituted C1-C3 alkyl, and wherein the composition comprises a non-ionic surfactant in an amount of less than 3 wt%.
- Cationic quaternary amino compounds are known in the art.
- US 4,264,479 and US 4,065,409 disclose surfactant systems comprising mixtures of a non-ionic detergent, a tertiary amine oxide or amphoteric detergent, and a quaternary ammonium halide.
- the detergent system has at least 3 surfactants present.
- WO03/031549 is directed towards a cleaning composition that is efficient in removing both food and industrial grease from hard surfaces.
- the improved cleaning compositions contain certain non-ionic surfactant and quaternary amine salts combined with a slightly water-soluble polar organic compound.
- the quaternary amine salts have a general formula wherein one alkyl has 10-20 carbon atoms and one alkyl has 1 to 5 carbon atoms. There is however no disclosure of a quaternary amine salt that has the general formula as depicted in claim 1, i.e. a amine salt with 3 short chain, alkyl (1-3 carbon atoms) or H, and 1 medium chain alkyl (10-16 carbon atoms).
- US 5,061,395 is directed to alkaline cleaning compositions comprising a combination of a cationic and a non-ionic surfactant with at least one chelating agent and an alkaline sodium component.
- the cationic surfactant may be an ammonium halide surfactant, however these ammonium surfactants comprise two lower alkyl (C1-C7 alkyl) and two substituents being either a phenyl group or a C8-C20 alkyl.
- a quaternary amine salt that has the general formula as depicted in claim 1, i.e. a amine salt with 3 short chain, alkyl (1-3 carbon atoms) or H, and 1 medium chain alkyl (10-16 carbon atoms).
- EP 0 621 335 is directed to an aqueous solution of a quaternary ammonium compound, a non-ionic surfactant and a glycol ether solvent.
- the quaternary ammonium surfactant comprises two lower alkyl (C1-C7 alkyl) and two substituents being either a phenyl group or a C8-C20 alkyl.
- US 4,443,363 discloses a detergent composition comprising a specific non-ionic surfactant and a selected quaternary ammonium surfactant wherein the quaternary ammonium is substituted with three C1-C8 alkyl and one C1-C4 alkyl.
- the present invention is directed to a cleaning composition comprising a quaternary ammonium compound.
- Quaternary ammonium compounds have the formula R1R2R3R4N+. It was found that mono-alkyl quaternary ammonium compounds were superior in cleaning performance. With mono-alkyl quaternary ammonium compounds is meant a quaternary ammonium compound wherein R1 being a medium alkyl substituent with a length between 10 and 16 C-atoms and R2, R3, and R4 each being a shorter alkyl substituent, i.e. C1-C3 alkyl, or being H. The C1-C3 alkyl may be substituted.
- C10-16 alkyl is an alkyl with a length between 10 and 16 C-atoms, e.g. decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl.
- C10-C16 alkyl may comprise a mixture of alkyl chain lengths from C10 to C16, wherein the mean alkyl chain length of the mixture is in the range C10-C16.
- Preferred R1 are C10-C14 alkyl, e.g.
- R1 is a linear alkyl.
- the shorter substituents R2, R3, R4 may be H or a short alkyl with 1 to 3 C-atoms, e.g. methyl, ethyl or propyl.

- Example 1 Primary (first-time) cleaning
- DHCO Dehydrated castor oil
- Cleaning compositions are evaluated on 10.0 x 10.0 cm pieces of 304 grade brushed stainless steel. Test pieces are previously unused, and are pre-cleaned prior to use.
- Test pieces are soaked for at least 1 hour in ⁇ 17 % by weight potassium hydroxide in 50/50 % by weight aqueous methylated spirits to remove any surface contamination from the metalworking process, which might influence wetting of the surface by the DHCO soil. After soaking, surfaces are thoroughly rinsed in running tap water and allowed to dry naturally in air, stored vertically.
- the stainless steel tile is pre-weighed (to 4 decimal places).
- a 5.0 x 5.0 cm area in the centre of the stainless steel surface is marked out by a square of adhesive masking tape.
- 0.040 gram (+/-4 mg) of DHCO is applied to the central templated area of the surface and distributed over the 25cm 2 area of surface using a purpose-made spreader, to produce an even film of oil.
- the masking tape template is carefully removed and the soiled tile is reweighed.
- test surfaces are heated in an oven at 100°C for 60 minutes. Test surfaces are allowed to cool and equilibrate for at least 1 hour. The test surface is reweighed and the weight of aged oil (W initial ) calculated.
- Cleaning by the composition under test is carried out in a Martindale Abrasion Tester apparatus (SDL International) over a fixed number of full lissajous figures (16 cycles), using a 1.5 cm diameter circle of non-woven cleaning cloth ('Ballerina', Unilever) attached to the cleaning head. By each full lissajous figure, the entire surface of the tile is cleaned once.
- the head has a total mass of 994 gram, applying a cleaning force of about 560 gram/cm 2 to the soiled test surface.
- the soiled tile is fixed centrally in the Abrasion Tester's sample well and 20.0 gram cleaning composition under test is introduced. Immediately, the cleaning head is secured in place and the Abrasion Tester apparatus run for the required number of lissajous figures. The cleaned tile is removed and rinsed free from cleaning product and any loose soil under a running tap. The surface is allowed to dry, stored vertically, and then reweighed. The weight of any remaining DHCO soil (W final ) is calculated.
- Soil Removal W initial - W final W initial ⁇ 100 %
- the outlined method is used to demonstrate the superior primary (first-time) cleaning of the compositions of the invention.
- compositions were at a fixed pH (11.4), adjusted by addition of sodium hydroxide or hydrochloric acid, as required.
- the above compositions are made to 100% with demineralised water.
- Examples 1 to 6 containing cationic surfactant according to the invention show a significant boost in tough oily soil removal compared to compositions with alcohol ethoxylate nonionic (comparative Example A), benzalkonium chloride cationic (comparative Example C) and secondary alkane sulphonate anionic (comparative Example D) as sole surfactant.
- Examples 1 and 3 with mono-coco and mono-C12-14 cationic surfactants give better cleaning compared to Example 5 with mono-C16 cationic surfactant.
- Example 2 binary mixtures of cationic and nonionic surfactants according to the invention (cationic:nonionic ratio 4:1), provide good cleaning.
- Example 2 is much superior to a binary composition of ratio 1:1.5 (comparative Example B).
- compositions were at a fixed pH (10.0), adjusted by addition of sodium hydroxide or hydrochloric acid, as required.
- the above compositions are made to 100% with demineralised water.
- Example 7 with mono-C12-14 cationic surfactant according to the invention, gives superior cleaning to alcohol ethoxylate or secondary alkane sulphonate (comparative Examples E & F).
- compositions of the invention Secondary (next-time) cleaning by compositions of the invention is demonstrated by the same basic method as previously described to assess primary cleaning, with the following differences in the method:
- compositions of the invention were at a fixed pH (10.0), adjusted by addition of sodium hydroxide, as required.
- the above compositions are made to 100% with demineralised water.
- the results show the ability of cationic surfactant in compositions of the invention (Examples 8 & 9) to deliver a secondary (next-time) cleaning effect on oily soil compared to alcohol ethoxylate nonionic (comparative Example G).
- the mono-coco cationic Arquad C-35 (Example 8) gives a statistically superior effect to mono-C12-14 Praepagen HY (Example 9).
- Arquad C-35 (Example 8) of the present invention gives as good a secondary cleaning effect as Genamin BTLF (C22 mono-alkyl cationic - comparative Example H) of prior art WO 98/28391 .
- Genamin BTLF C22 mono-alkyl cationic - comparative Example H
- cationic surfactants of WO 98/28391 are more difficult to formulate than the cationic surfactants of the present invention and do not provide as good primary cleaning of tough oily soils.
