Definitions

  • the present invention relates to a liquid detergent composition that provides desirable foaming and soil removal properties. More particularly, the invention concerns a foaming aqueous detergent composition that contains:
  • liquid detergent compositions according to the present invention include liquid hand dishwashing detergents and liquid hard surface cleaning compositions.
  • liquid detergent compositions according to the invention readily form a cleaning liquid with a rich, creamy foam when mixed with water. After cleaning, the foam can easily be removed from cleaned surfaces by rinsing the surface with only a small amount of rinsing water.
  • One way of saving water is to reuse the water and another way is to reduce the amount of water being used.
  • Washing processes including laundry, dishwashing and other household cleaning processes, require large amounts of water throughout the world.
  • the amount of water required in these washing process is largely determined by the amount of water needed to rinse the newly cleaned article or surface.
  • large quantities of water are required to rinse off the foam residues.
  • Liquid detergent compositions are widely used to clean all kinds of articles and surfaces. These liquid detergent compositions should be capable of removing all kinds of soils. Furthermore, in order to achieve a good cleaning result, redeposition of soils onto the newly cleaned articles or surfaces should be prevented.
  • liquid detergent composition it is also desirable for the liquid detergent composition to provide sustained foaming in dilute cleaning liquid in the presence of the soils being cleaned. However, once an article or surface has been cleaned, this foam is no longer desired and should be removed with difficulty, e.g. by rinsing. Especially in view of the growing scarcity of consumable water it is important to provide liquid detergent compositions that on the one hand provide sustained foaming in the dilute cleaning liquid and that on the other hand provide fast and easy removal of foam residue by rinsing.
  • WO 99/35237 describes a clear microemulsion liquid cleaning composition which comprises approximately by weight:
  • WO 00/59454 describes a liquid lamellar cleansing composition comprising:
  • WO 2006/081944 describes a low foaming aqueous liquid detergent composition comprising a carboxylic ester and/or low-degree alkoxylated derivative, surfactant and water.
  • WO 2016/030226 describes a liquid detergent composition having foaming and cleaning characteristics in the main wash, yet significant foam reduction during rinse.
  • the compositions comprise an anionic surfactant system, nonionic surfactant and saturated fatty acids.
  • US 4017409 describes liquid household cleaner compositions comprising anionic surfactants, organic or inorganic builder salts, a suds suppressing system comprising fatty acid ester and water.
  • WO 2011/075642 describes a foaming liquid detergent composition comprising:
  • the inventors have developed a liquid detergent composition which is very effective in removing soil from surfaces and which, upon dilution with water, readily produces a cleaning liquid with a rich, creamy foam, which foam can easily be removed from the cleaned surface using only a limited amount of rinsing water.
  • the liquid detergent composition of the present invention comprises:
  • first and second anionic surfactants in the liquid detergent composition are largely responsible for the formation of a rich, creamy foam when the detergent composition is mixed with water to prepare a cleaning liquid.
  • the fatty acid ester of the liquid detergent composition was found to substantially improve foam rinsability after cleaning.
