Definitions
- the present invention relates to the use of bentonite or one or more derivatives thereof in a fabric treatment composition to provide anti-wrinkle properties and/or ease of ironing benefits to a fabric treated with said fabric treatment composition.
- the invention further relates to a method of reducing the creasing of fabric, and to a method of providing ease of ironing benefits to a fabric.
- Ironing of fabrics after laundering is generally regarded as one of the most unpopular household chores. There have, to date, been two approaches taken to making ironing less of a household chore.
- the first approach has been to make the ironing process easier (involving less time and effort for the person doing the ironing). This is referred to herein as an ease of ironing effect.
- silicone oils have been used in rinse conditioners to give this effect.
- the second approach has been to try to prevent garments becoming creased (this is referred to herein as an anti- creasing effect) during the laundering process, thus eliminating the need for ironing.
- This approach is disclosed in e.g. EP 150 872 .
- This second approach has several additional advantages over the first; firstly, it is attractive to consumers because they will not have to iron the fabrics at all (thus saving time and effort, and, avoiding a household chore completely) and secondly it reduces energy consumption and hence is environmentally favorable.
- This second approach has generally been found to be more difficult to achieve. However, it has been found that increased levels of active ingredients are often required in the product to achieve the effect.
- the present invention is directed towards providing reduced creasing of fabric during laundering and/or easier ironing of fabric that has been laundered.
- bentonite or one or more derivatives thereof contained in fabric treatment compositions provide for anti-wrinkle effects and/or ease of ironing effects. Furthermore, wearing comfort after ironing of the fabric is improved due to moisture managing properties of the bentonite.
- the present invention therefore relates to the use of bentonite or derivatives thereof in a fabric treatment composition to provide anti-wrinkle properties and/or ease of ironing benefits to a fabric treated with said fabric treatment composition.
- the present invention relates to a method of reducing the creasing of fabric by applying thereto during a laundering operation a fabric treatment composition comprising bentonite or one or more derivatives thereof.
- the invention relates to a method of providing ease of ironing benefits to a fabric by
- the present invention relates to the use of bentonite or one or more derivatives thereof as ironing aids in fabric treatment compositions.
- At least one relates to one or more, i.e. 1, 2, 3, 4, 5, 6, 7, 8, 9, or more. If used in combination with a compound, the term does not relate to the absolute number of molecules but rather to the number of different types of said compound. "at least one surfactant” thus means that at least one type but that also 2 or more different surfactant types can be present.
- viscosities referred to herein are viscosities measured at 20°C by a Brookfield LVT, Spindle No. 3 at 12 rpm.
- Free of means that the referenced composition does not contain more than 0.5 wt.%, preferably no more than 0.1 wt.%, more preferably no more than 0.05 wt.% of said component relative to the total weight of the composition. Most preferably, said component is not contained at all.
- the fabric treatment compositions as described herein may be used as detergents for textiles, carpets or natural fibers, fabric conditioners, as well as treatment compositions for pre laundering treatment of fabrics, and post-laundering treatment of fabrics.
- the present invention is based on the inventors' surprising finding that by use of bentonite and/or one or more derivatives thereof in fabric treatment compositions, anti-wrinkle effects and/or ease or ironing effects may be achieved. Furthermore, wearing comfort after ironing of the fabric is improved due to moisture managing properties of these types of minerals.
- the present invention relates to the use of bentonite or derivatives thereof in a fabric treatment composition to provide anti-wrinkle properties and/or ease of ironing benefits to a fabric treated with said fabric treatment composition.
- Bentonites are clays that are comprised primarily of, and whose properties are typically dictated by, a smectite clay mineral (e.g. montmorillonite, hectorite, nontronite, etc.). Smectites are generally comprised of stacks of negatively charged layers (wherein each layer is comprised of two tetrahedral sheets attached to one octahedral sheet; the tetrahedra formed by silicon and oxygen atoms and the octahedra formed by aluminum and oxygen atoms together with hydroxyl radicals) balanced and/or compensated by alkaline earth metal cations (e.g.
- alkali metal cations eg. Na + and/or K + .
- the relative amounts of the two types (alkaline earth metal and alkali metal) of cations typically determine the swelling characteristic of the clay material when placed in water.
- Bentonites, in which the alkaline earth metal cation Ca 2+ is predominant (or is in a relative majority), are called calcium bentonites; whereas, bentonites in which the alkali metal cation Na + is predominant (or is in a relative majority) are called sodium bentonites.
- a preferred clay is bentonite clay, which comprises predominantly montmorillonite clay.
- bentonite in the form of natural bentonite and/or bentonite in the form of synthetic bentonite, in the context of the present invention referred to as "derivatives of bentonite”, may be employed advantageously.
- natural refers to the presence of the mineral in deposits found in the earth (formed via modification of volcanic ash deposits in marine basins by geological processes). Accordingly, a natural deposit of bentonite containing primarily (or a relative majority of) Na + cations may be referred to as natural sodium bentonite, whereas, a natural deposit of a bentonite predominantly containing (or containing a relative majority of) Ca 2+ cations may be referred to as natural calcium bentonite.
- Synthetic bentonites for example synthetic analogues of Na and Ca bentonite, may also be synthesized (by using hydrothermal techniques, for example).
- Synthetic sodium bentonite may also refer to bentonite obtained by treatment of calcium bentonite with, but not limited to, sodium carbonate or sodium oxalate (to remove the calcium ion and substitute it with a sodium ion). Typically, such a treatment may be varied to impart different levels of ion-exchange or Na + for Ca 2+ substitution.
- Natural sodium bentonite (generally, irrespective of the part of the world in which the deposit is located) is colored. The color ranges from brown to yellow to gray. By comparison, natural calcium bentonite has a more aesthetically pleasing white color. Consequently, synthetic sodium bentonite that is obtained by treatment of this white calcium bentonite is also white. As a result, natural calcium bentonite and synthetic sodium bentonite find more widespread use in the detergent industry, as compared to natural sodium bentonite.
- the fabric treatment composition as described herein comprises natural sodium bentonite and/or natural calcium bentonite.
- the clay may exhibit a particular range of particle size, as determined, for example, by sieving techniques according to ASTM D1921-06 ("Standard Test Method For Particle Size (Sieve Analysis) of Plastic Materials"). Alternative methods known to those skilled in the art may also be utilized for determining particle size. For example, other sieving techniques may be used or electronic laboratory equipment known for determining particle size may alternatively be employed.
- the clay may be characterized by having a particle size such that at least 95 wt % of the clay has a particle size that is in the range from 50 micrometers to 2,000 micrometers, preferably from 50 micrometers to 1,500 micrometers, or from 50 micrometers to 1,000 micrometers, or from 50 micrometers to 500 micrometers, or from 50 micrometer to 300 micrometers, or from 50 to 200.
- the clay can be characterized by having an average particle of 50 micrometers to 2,000 micrometers, preferably from 50 micrometers to 1,500 micrometers, or from 50 micrometers to 1,000 micrometers, or from 50 micrometers to 500 micrometers, or from 50 micrometer to 300 micrometers, or from 50 to 200.

- soil release polymer refers to polymeric soil release agents having soil release properties, i.e. having the property to enhance the cleaning efficacy of the cleaning composition by improving release of greasy and oil during the laundry process.
- Polymeric soil release agents are characterized by having both hydrophilic segments, to hydrophilize the surface of hydrophobic fibers, such as polyester and nylon, and hydrophobic segments, to deposit upon hydrophobic fibers and remain adhered thereto through completion of washing and rinsing cycles and, thus, serve as an anchor for the hydrophilic segments. This is commonly done to enable stains occurring subsequent to treatment with the soil release agent to be more easily removed in later washing procedures.
