Definitions

  • the present invention is in the field of hard surface treatment compositions; and in particular relates to hard surface treatment compositions to render a substrate hydrophobic and also repellent to aqueous stains and soils, as well as giving good cleaning on tough soils and stains.
  • Water droplets have a tendency to stick to surfaces. These water droplets are usually a mixture of water and fine particulate matter in the form of dust or dirt. The particulate matter is either present on the surface before being wetted or is already in a mixture with water when the droplets come in contact with the surface. When the water droplets settle on a surface and eventually dry up, they leave spots or streaks on the surface giving a stain-like appearance. Such an appearance on surfaces is not appreciated by present day consumers.
  • Metal soap based compositions have been proposed in the past for imparting hydrophobicity to surfaces.
  • Our co-pending application IN-2963/MUM/201 1 describes hard surface cleaning compositions. It particularly relates to a method and composition for cleaning of a surface and imparting repellence of soils. It relates to the object of providing a stable surface cleaning composition which can make the surface hydrophobic and oleophobic as well as provide superior cleaning; and proposes a composition comprising fluoro silane with a solvent and a polyvalent metal salt was found to render both hydrophobicity and oleophobicity making the surface less susceptible to soiling, by both aqueous and oily stains and also provides better cleaning.
  • composition described therein is an opaque composition due to the presence of metal complexes, and the use of which is also less preferred as is it not perceived as being eco-friendly.
  • hydrophobic composition which is transparent and devoid of metals.
  • US 2004/0077517 and US 2004/0171515 disclose laundry (wash, rinse or care) composition comprising a cationically modified polymer and metal ions and cationic surfactants. They further disclose that the formulation may be applied onto both soft and hard surfaces. They further disclose the use of solvents including low molecular weight alcohols and glycols. What remains to be desired is a composition that imparts improved hydrophobicity to a surface.
  • US 2004/0077517 and US 2004/0171515 do not disclose the use of glycol ethers in the compositions. The present inventors have shown that inclusion of glycol ethers enhance the repellence to water in addition to cleaning.
  • IN-1293/MUM/201 1 describes a hard surface cleaning composition comprising poly- aluminium-chloride (PAC), soap of C8-C18 fatty acid, a surfactant selected from non- ionic surfactants or quaternary ammonium cationic surfactants, poly vinyl alcohol(PVA) and a quaternary silicon oil.
  • PAC poly- aluminium-chloride
  • PVA poly vinyl alcohol
  • metal soaps formed therein contribute to the opaqueness of the composition, thereby leaving a need for transparent hydrophobic compositions.
  • Hard surface cleaning compositions comprising carboxylic polymers are disclosed in W097/24425 (The Procter & Gamble Company). These compositions provide improved cleaning and especially improved gloss on a surface, thought to be caused by the combination of a carboxylic polymer, surfactant and a divalent ion. However, improved results on the subsequent cleaning remain to be desired.
  • compositions providing a next time cleaning benefit are not performing well on cleaning; they do not provide good stain removal, and leave water streaks and/or spots after wetting a treated surface upon drying. It is therefore an object of the present invention to provide easier cleaning upon the subsequent wash; also knows as a next time cleaning benefit.
  • composition comprising a solvent, a carboxylic polymer, a metal ion and a cationic surfactant and having a pH of between 2 and 6, provides both stain repellence as well as good primary and secondary cleaning.
  • the present invention provides a hard surface cleaning composition
  • the invention further provides for a method for cleaning a hard surface comprising the steps in sequence of: (a) treating a surface with the composition according to anyone of the preceding claims; (b) leaving the surface for soils or stains to deposit; and (c) cleaning the surface with the compositions according to any one of the preceding claims.
  • primary cleaning is meant that the composition itself, upon first use on a surface provides cleaning efficacy.
  • secondary cleaning is meant that after first applying the composition to a surface, then leaving it to dry and leaving it for dirt to deposit, cleaning efficacy is obtained while applying the composition for a second or subsequent time.
  • the invention provides a hard surface treatment composition
  • sodium/potassium of the following acids: acrylic acid, C2-7 dicarboxylic acids; a water miscible glycol ether; a siloxane; a metal salt and a cationic surfactant, wherein the pH is from 2 to 6, preferably from 3 to 5.
  • the composition leaves a deposition of a complex on the hard surface that is treated with the composition.
  • the polymer-metal complex that forms in the current composition provides a more hydrophobic layer that is better and more homogeneously deposited onto the surface than the hydrophobic layers that have been disclosed in the art.
  • the deposition is only achieved in the pH range of the invention. This imparts hydrophobicity to the surface and makes it water repellent. Hydrophobicity is measured by the contact angle of a water droplet on a treated surface. A contact angle above 90° is acceptable, above 100° is preferred.
  • the polymer is typically a block or alternate copolymer having moieties A and B, wherein:
  • A polystyrene, polyethylene, polypropylene, polyisobutylene, and
  • B Water soluble alkali metal salt (sodium/ potassium) of the following acids: acrylic acid, C2-7 dicarboxylic acids;
  • the copolymer may be a styrene/maleic copolymers, selected from block or alternate copolymer having, wherein A is selected from polystyrene; and B is maleic acid, forming the preferred polymers including
  • Block copolymers consist of two or more block sequences, at least one of which is not a homopolymer or uniformly random copolymer sequence. In case of random copolymers the composition changes continuously along the polymer chain and with conversion, without giving rise to a detectable block structure (JOURNAL OF APPLIED POLYMER SCIENCE VOL. 1 1 , PP. 1581-1591 (1967))

  • the polymer composition concentrations beyond the scope of the invention deteriorate hydrophobicity.
  • the composition comprises a water miscible glycol ether to improve the hydrophobicity or water repellency imparted by the composition, and to also enhance the cleaning properties of the composition. It is thought that these properties are imparted to the composition due to the HLB of the glycol ether.
  • Water miscible glycol ethers used in the present invention are of the formula wherein, is a substituted or unsubstituted C 2 - C 4 alkyl group, aryl group (preferably phenyl), or alkylaryl group; and R 2 is a substituted or unsubstituted C 2 - C 4 alkylene group.

  • water miscible it is meant that at least 5% of the glycol ether is soluble in or miscible with water.
  • the composition further comprises a metal ion. It is thought that the metal ion of the salt aids in the deposition of a complex on the surface and imparts additional hydrophobicity. This is thought to be due to the metal polymer complex formation, which deposits on the surface of the substrate. It also aids the deposition of the optional siloxane onto the surface. It is further thought that a higher positive charge on the metal ion also helps in deposition on negatively charged surfaces like glass or ceramics.
  • the metal ion is selected from water soluble trivalent and tetravalent metal ions; and/or bi valent transition metal ions. Any combination of two or more of the metal or transition metal ions is also included in the purview of the present invention.
