Description

Unit dose tablet compositions

Technical field

The present invention relates to unit dose tablet compositions. The invention further relates to methods of preparing such compositions and methods of treating surfaces with such compositions.

Background technique

Unit dose cleaning compositions, such as detergent tablets, are among the most popular products among consumers due to their ease of handling, dispensing and storage. This composition is used for cleaning surfaces such as bathroom surfaces, kitchen surfaces and cleaning laundry surfaces.

There have been many attempts to formulate unit dose cleaning compositions that are resistant to breakage (to withstand transportation, accidental drops, etc.) yet dissolve quickly. However, there is a dichotomy in that as compression force is increased in an attempt to provide a composition that is resistant to breakage, the dissolution rate of the tablet becomes slower. On the other hand, low compression improves solubility at the expense of tablet strength. This problem is exacerbated by the fact that conventional tablet compositions have relatively poor long-term storage stability characteristics and, to compensate, must be manufactured to higher compression specifications.

Attempts to provide unit dose cleaning compositions of acceptable strength and solubility have been described in the art. For example WO 2000/43488 A1 discloses a detergent tablet for washing machines having one or more phases, at least one of which is in the form of a compressed granular solid, said tablet comprising: a) a polymer a disintegrant having a particle size distribution such that at least 90% by weight thereof has a particle size below about 0.3 mm and at least 30% by weight has a particle size below about 0.2 mm; and b) water-soluble A hydrated salt having a solubility of at least about 25 g/100 g in distilled water at 25°C.

However, the detergent tablets of WO 0043488 A1 still had poor solubility when added to a bowl of water, which meant that the detergent tablets did not meet consumer expectations, especially in washing laundry.

GB 2 339 575 A (PROCTER&GAMBLE) discloses cellulose disintegrants for detergent compositions.

DE 198 43 938 A1 (HENKEL KGAA) discloses shaped bodies for washing and cleaning agents which contain as formulation component a material selected from the group consisting of alkali metal sulfates and/or alkaline earth metal sulfates and/or alkaline earth metal carbonates and/or alkaline earth metal phosphoric acid.

These shaped bodies are said to comprise advantageous properties with regard to application technology if at least 60% by weight of the specified alkali metal salts and/or alkaline earth metal salts contain particle sizes greater than 600 microns.

The tablets are said to exhibit good disintegration properties.

In one embodiment, the sterile tablet contains sodium dichloroisocyanurate dihydrate and at least one swellable disintegrant that aids in rapid disintegration of the tablet. A disinfecting cleaning tool assembly and cleaning method are also disclosed.

The composition is also advantageous in that it requires less filler than typical tablet dosage compositions.

Preferably, the unit dose cleaning composition contains no more than 15% by weight filler, more preferably no more than 10% by weight, and most preferably no more than 7% by weight filler.

Preferably, though, the composition includes some filler, and this should be at least 5% by weight of the composition.

More preferably, the unit dose cleaning composition has a DFS _air /DFS _water radial fracture stress (DFS) ratio in the range of 6 to 50, preferably 7 to 45.

The DFS _air /DFS _water ratio can be measured using techniques known to those skilled in the art. DFS can be measured using a texture analyzer such as the CT3 Brookfield Texture Analyzer. For example, DFS _air /DFS _water can be measured using a TA instrument model TA-XT2i and Texture Experte software (Texture Technologies Corp., Scarsdale, NY, USA/-Stable Micro Systems, Surrey, England, UK). The instrument is calibrated using a 5kg load cell and equipped with a stainless steel flat-bottomed cylindrical probe (Kobe probe) with a surface area of ^1cm2 . The method involves positioning the tablet on the flat surface of the probe. The probe moves until a trigger force is detected, at which point TA is set to maintain a predetermined nominal force for a given period of time (60 seconds). When a tablet begins to disintegrate, TA measures the distance through which the tablet is compressed when immersed in a medium (water). During the experiments, the constant temperature of the medium was maintained at 18° C. by means of a thermos-type double-walled bath and a heat bath/circulator (Haake, Karlsruhe, Germany).

Examples of the aforementioned nonionic surfactants include, but are not limited to, Neodol (trademark, available from Shell) ethoxylate, which is a higher primary aliphatic alcohol containing about 9 to 15 carbon atoms, for example, with 4 to 10 moles of epoxy C9 to C11 alkanol condensed with ethane (Neodol 91-8 or Neodol 91-5), C12-13 alkanol condensed with 6.5 moles of ethylene oxide (Neodol 23-6.5), condensed with 12 moles of ethylene oxide C12-15 alkanol (Neodol 25-12), C14-15 alkanol condensed with 13 moles of ethylene oxide (Neodol 45-13), etc. Such ethoxy condensates (ethoxamers) have HLB (hydrophobic-lipophilic balance) values of about 8 to 15 and provide good O/W emulsification, while ethoxy condensates with HLB values below 7 contain less than 4 ethylene oxide groups and tend to be poor emulsifiers and poor detergents.

Suitable amphoteric surfactants include derivatives of aliphatic secondary and tertiary amines containing an alkyl group of 8 to 18 carbon atoms and an aliphatic group substituted by an anionic hydrosolubilizing group, such as 3-dodecylamine.
