Definitions
- the present invention refers to a liquid rinse aid composition
- a liquid rinse aid composition comprising a biosurfactant selected from the group of mannosylerythritol lipids, the use of such compositions in an automatic dish washer and methods for cleaning kitchenware and/or tableware in an automatic dishwasher comprising bringing such a composition into contact with said kitchenware and/or tableware during the rinse step.
- Rinse aids are added during the rinsing step of automatic dishwashing programs to prevent droplet formation, so that water drains from the surfaces in thin sheets, rather than forming droplets, which prevents "spotting".
- “Spotting" on washed items is caused by droplets of water drying and leaving behind dissolved limescale minerals, thereby rendering the washed table- or kitchenware less attractive to the consumer.
- Rinse aids can also improve drying performance as there is less water remaining to be evaporated off the washed items.
- a thinner sheet of water also has a larger surface-area than a droplet of the same volume, which increases the likelihood of water molecules evaporating. This results in less energy consumption in order to dry the washed items.
- rinse aids comprising nonionic surfactants.
- conventional rinse aids entirely rely on nonionic surfactants derived from ethoxylated fatty alcohols.
- Such surfactants are synthesized from petroleum fractions and therefore require high amounts of energy and non-renewable resources during production. Consequently, there is a need for rinse aid compositions being more environmentally friendly and saving recources. It was therefore an object of the present invention to provide a rinse aid composition yielding excellent spotting results, in which at least a part of conventional nonionic surfactants is saved. This object is met by the use of particular, selected surfactants known in the art as biosurfactants.
- Biosurfactants are surfactants which can be produced by biotechnological processes, i.e. using fungi or bacteria, from renewable resources, like sugars and/or oils derived from plants.
- a further advantage of biosurfactants is that these compounds are readily biodegradable.
- a drawback of the replacement of conventional nonionic surfactants by biosurfactants is a decrease in drying and spotting performance of the resulting rinse aids.
- the present inventors have surprisingly found that drying and spotting performance of rinse aid compositions comprising biosurfactants can be improved by incorporating mannosylerythritol lipids into such rinse aid compositions.
- Mannosylerythritol lipids are molecules having the general formula (I) below.
- n may be an integer having a value between 1 and 24, preferably between 2 and 18, more preferred between 4 and 12 and between 14 and 18, most preferred 3, 4, 5, 9, 10, 11, 15, 16 or 17.
- Such biosurfactants are typically produced using bacteria of the species Pseudozyma or Ustilago.
- Mannosylerythritol lipids have previously been described as used in cleaning compositions.
- WO 2018/197623 A1 WO 2015/091250 A1 and WO 2018/191174 A1 describe compositions comprising biosurfactants useful for cleaning hard and/or soft surfaces.
- EP 3 290 020 A1 and US 2010/168405 A relate to the use of mannosylerythritol lipids in medicinal or cosmetic compositions, while WO 2016/066464 A1 , EP 3 341 458 A1 , EP 3 290 500 A1 , DE 10 2015 217 506 A1 and DE 10 2014 225 184 A1 refer to mannosylerythritol lipid containing detergents, particularly laundry detergents.
- Mannosylerythritol lipids may also be used as thickeners or corrosion inhibitors, as disclosed in WO 2018/167285 A1 and EP 2 872 480 A1 , or WO 2018/095975 A1 , respectively.
- the rinse aid composition according to the present invention is defined as being free of a specific component, "free" in this context means that, despite efforts taken to avoid the presence of said component in the rinse aid composition, a total amount of not more than 10 ppm, preferably not more than 5 ppm, more preferred not more than 2 ppm of said component may be present in the rinse aid composition according to the present invention. Most preferred the inventive rinse aid composition contains less than 1 ppm, or 0 ppm of any undesired components.
- the rinse aid composition according to the present invention comprises at least one biosurfactant selected from the group of mannosylerythritol lipids.
- Said biosurfactant(s) may be of any of the subtypes MEL-A to MEL-D as defined in Formula (I) above or a mixture of mannosylerythritol lipids of said subtypes.
- This means that of the two hydroxy groups present in the at least one biosurfactant, 0 to 2 may be acetylated and n may be an integer having value between 1 and 24, preferably between 2 and 18, more preferred between 4 and 12 and between 14 and 18, most preferred 3, 4, 5, 9, 10, 11, 15, 16 or 17.

- the rinse aid composition according to the present invention is a liquid rinse aid composition. It may therefore comprise 50 to 98 wt.-%, preferably 75 to 95 wt.-%, more preferred 80 to 90 wt.-%, based on the total weight of the rinse aid composition, of a solvent or a mixture of solvents.
- the solvent or mixture of solvents may comprise one or more solvents selected from water, ethanol, 2-propanol and/or glycerol and preferably comprises water.
- the rinse aid composition according to the present invention is free of enzymes cleaving such bonds.

- RL 1 200 abbreviated as Raphynal V1 200
- RL 2 a mixture of approx. 65 to70 % diramnolipids and approx. 15 to 20 % mono-ramnolipids
- RL 3 sophorolipid-based biosurfactant
- MEL mannos
- Dishes were washed in a Miele GSL-2 dishwasher over 6 cycles in the standard program at 50 °C (rinsing time 8 minutes). The water hardness was 9 °GH.
- Dishes were checked for droplets and spotting after 4, 5 and 6 cycles, respectively.
- the number of droplets were determined 30 minutes after finishing the respective number of cycles, while spotting was determined 3 hours after finishing the respective number of cycles, both by visual inspection of an experienced person.
- Drying performance was rated on a scale of 0 to 10, wherein 0 stands for no droplets remaining on the respective dishes and wherein 10 stands for a high number of droplets.
- Results are shown in Figures 1 and 2 .
- the values are given as average values over 4, 5 and 6 cycles for all dishes of the same respective material and as average values for all dishes over 4, 5 and 6 cycles (right column).
- an inventive rinse aid composition comprising mannosylerythritol lipids as biosurfactants shows better average drying and spotting performance over all tested dishes than rinse aids containing other biosurfactants.
