Definitions

  • Cleaning compositions known in the art for cleaning toilet bowls are effective at maintaining a hygienic surface (antimicrobial), but typically such cleaning compositions, tend to have low cleaning efficacy on submerged surfaces.
  • any feature of one aspect of the present invention may be utilised in any other aspect of the invention.
  • the word “comprising” is intended to mean “including” but not necessarily “consisting of” or “composed of”.
  • the term “comprising” is meant not to be limiting to any subsequently stated elements, but rather to optionally also encompass non-specified elements of major or minor functional importance. In other words, the listed steps or options need not be exhaustive.
  • the words “including” or “having” are used, these terms are meant to be equivalent to “comprising” as defined above. It is noted that the examples given in the description below are intended to clarify the invention and are not intended to limit the invention to those examples per se.
  • the sum of a), b), c) and d) is in the range of 0.1 to 10 wt%, more preferably 1 to 9 wt%, even more preferably 2 to 8 wt%, most preferably 3 to 7 wt%.
  • the one or more unsaturated terpenes comprises limonene, alpha-terpinene, terpinolene, cymene, phellandrene or mixtures thereof, more preferably limonene.
  • unsaturated terpene preferably means that the terpene does contains unsaturated (carbon-carbon) bonds and does not contain a hydroxy group.
  • the substituted phenol, the aliphatic terpene alcohol and the unsaturated terpene are present in the ratio 1:0.5:0.5.
  • a substituted phenol e. g. thymol or eugenol or butyl phenol
  • an aliphatic terpene alcohol e. g. menthol
  • an unsaturated terpene e. g. limonene, alpha terpinene or terpinolene is present in 0.5 part.
  • the composition comprises an effervescent system having a basic component and an acidic component.
  • a method of preparing a unit dose cleaning composition comprising the steps: i. combining a basic component, an acidic component and a cationic surfactant, with a) one or more substituted phenols selected from thymol, sec-butylphenol, carvacrol, eugenol, propylphenol or mixtures thereof, preferably thymol, b) one or more aliphatic terpene alcohols, preferably menthol; and c) one or more unsaturated terpenes selected from limonene, alpha-terpinene, terpinolene, cymene, phellandrene or mixtures thereof, preferably limonene to provide a cleaning composition, preferably a solid cleaning composition.
  • compositions in tablet form) according to Table 1 were prepared.
  • a limescale removal test was carried out in a plastic device having similar shape and dimension of a typical siphon of a toilet.
  • 12 tablets (per composition according to Table 1) were mounted on a silicon plate (P) on the inclined side (60° angle) of the apparatus (corresponding at 24 cm 2 area).
  • a second silicon plate (L) had 8 limescale tablets (corresponding at 16 cm 2 area) mounted on it placed horizontally on the bottom of the apparatus.
  • the device was filled with 2 litres of tap water, afterwards 80 g of neat products (mentioned in Table 1) are added. After 30 minutes contact time, the mounted tablets are removed, rinsed for 30 seconds under gently running tap water and then dried at 70 ° C overnight before re-weighing to calculate the tablets weight loss. A minimum of 3 replicates are used to assess each system.
  • limescale removal ability of compositions according to the invention was also evaluated using Carrara marble tiles (8 cm c 3 cm c 1 cm) as a representative surface.
  • the method measures the level of dissolution of calcium carbonate which is the main component of the marble as well as limescale. Calcium carbonate dissolution obtained due to these test compositions is then evaluated by gravimetric method. Briefly, the tiles were cleaned with dried with compressed air to remove marble residues followed by placing them in an oven (105°C for 2h). After 2h, the tiles were removed and were cooled at room temperature in a glass dryer; and were weighed to record the ‘initial weight’ in grams. Such tiles were then used further.
  • the tiles were soaked into a plastic cylinder with 80 g of test compositions (10 g of a composition dissolved in 70 mL water) shown in table 3 for 1h (along with a solution at 2% HCI as reference that provided 4.01 ⁇ 0.03 % soil removal). After this, the tiles were rinsed under tap water to remove all product residues. The tiles were then placed in an oven (105°C for 2 h), cooled at room temperature in a glass dryer thereafter; and weighed to record the ‘final weight’ in grams.
