Definitions
- the present invention relates to fabric treatment compositions which comprise a transition metal cation sequestrant and a dispersant, and are suitable for domestic use.
- the invention also relates to a method of conferring an improved whiteness benefit to white textile articles during fabric laundering.
- the effectiveness of these fluorescent whitening agents is dependent on the amount of UV light and the quantum yield (a measure of the efficiency of the UV to visible light conversion process). Thus, a reduction in available UV light or a reduction in the quantum yield will be seen as a reduction in whiteness.
- the present invention therefore provides in a first aspect, a method of conferring an improved whiteness benefit to a white textile article during a laundry process, comprising the steps of:
- an aqueous liquor comprising a laundry treatment composition which comprises a florescent whitening agent and an active agent, and, b) contacting the white textile article with the aqueous liquor of a);
- a transition metal cation sequestrant i) a transition metal cation sequestrant; and, ii) a dispersant which comprises one or more of naphthalene sulphonate- formaldehyde condensates, acrylic polymers, sulphonated styrene/maleic anhydride copolymers or a mixture thereof; and, that the white textile article is first contacted with the laundry treatment composition comprising the active agent during a wash step, and is further contacted with active agent made available from a different and separate rinse-added laundry treatment composition.
- the method to improve whiteness involves contact of the white textile article with further active agent. This may occur from providing additional composition comprising the active agent (either in a similar product format or different product format) to subsequent steps of the laundry process.
- the 'active agent' described herein refers to an agent comprising two parts, the transition metal cation sequestrant and dispersant.
- the white textile article is contacted with further active agent during the laundry process. This may suitably happen in various ways.
- contact with further active agent may suitably happen by addition of a second portion of active agent to a subsequent laundry step, i.e. the active added to the main wash and to one or more rinse steps.
- the laundry treatment composition comprises an anionic or nonionic detersive surfactant, where the further active agent is incorporated in a different and separate rinse- - A -
- the rinse-added laundry treatment composition comprises a quaternary ammonium compound.
- the aqueous liquor of a) is an aqueous main wash liquor, and contact with further active agent occurs during a rinse step of the wash process. More preferably, contact with further active agent occurs during the final rinse step of the wash process. Even more preferably, contact with further active agent occurs during all rinse steps of the wash process.
- the transition metal cation sequestrant is able to bind Cu" and/or Fe".
- the sequestrant has a binding capacity (log k) for copper(ll) and iron(ll) of greater than 8.
- Non-limiting examples include tetrasodium etidronate, ethylenediamine tetraacetic acid (EDTA), iminodisuccinic acid sodium salt (IDS), ethylene diamine disuccinic acid trisodium salt (EDDS), ⁇ /, ⁇ /, ⁇ /', ⁇ /'-tetrakis (2- hydoxypropyl) ethylene diamine (TPED), gluconic acid sodium salt, nitrilotriacetic acid sodium salt monohydrate (NTA), (1 -hydroxy ethylidene) diphosphonic acid potassium salt.
- IDS for example BaypureTM CX (ex. Bayer), and TurpinalTM 4NP (ex. Solutia).
- Suitable dispersants include naphthalene sulphonate-formaldehyde condensates, acrylic polymers, and sulphonated styrene/maleic anhydride copolymers.
- the laundry composition used in the method of treatment comprises a fluorescent whitening agent.
- it may comprise a blue or violet dye instead of, or additionally to the fluorescent whitening agent.
- fluorescent whitening agents can be found in "Formulating Detergents and Personal Care Products", Louis Ho Tan Tai, published in 2000 by AOCS Press, at pages 125-128.
- the fluorescent whitening agent is typically present in detergent formulations at a level of 0.1 wt.% on weight of total formulation.
- the sequestrant and dispersant present in the method according to the invention are present in the aqueous liquor at a level of from 0.001 g/L to 1.Og/L, preferably from 0.0015g/L to 0.5g/L, to each required stage of the wash process.
- Extended release for a main wash composition means that release of the active agent (the sequestrant and dispersant) occurs at least in part after the main wash of a laundry process.
- An example is a composition which releases active species across the wash, i.e. active species are released during the main wash and at least the first rinse step.
- the delayed release composition will release active species across the main wash and all subsequent rinse steps.
- An improved whiteness benefit as used herein is defined as either enhancing the whiteness of the textile article, or otherwise preserving the perceived whiteness of the textile article from damage by the washing process.
- the white textile article is defined as a textile article which comprises substantial white areas; preferably, it is a solely white textile article.
- the textile article is cotton or cotton rich.
- the article comprises at least 50% cotton fibres by weight.
- the present invention is based on the surprising finding that ensuring the extended presence of a transition metal cation sequestrant and dispersant that can bind or prevent aggregation of metal species, in certain stages of a domestic wash cycle (i.e. both the main wash and at least one of the rinse stages) produces an unexpectedly large whiteness benefit when compared to addition of the active agent in just the main wash.
- the method of the invention is applied to a white textile article, preferably a non- keratinaceous textile article, more preferably a cellulosic or cellulose containing textile article.
- the laundry process to which the method of the present invention applies can be any laundry process comprising a wash and a rinse step.
- the process may be manual, such as hand-washing or, more preferably, semi-automatic or automatic such as performed by an automatic washing machine.
- the laundry process generally comprises at least one main wash step and a final rinse step. Typically, there will be more than one rinse step.
- a laundry process according to the present invention preferably comprises a main wash step, at least one, preferably two, most preferably three or more intermediate rinse steps and a final rinse step.
- the laundry process is preferably facilitated by an automatic washing machine.
- Such a laundry process typically comprises at least one main wash step, in which textile articles are contacted with the or each main wash liquor.
- This liquor comprises an aqueous solution or dispersion of a main wash detergent product.
- the main wash liquor is usually drained from the machine and one or more rinses takes place. Typically a series of sequential rinses takes place, culminating in a final rinse.
- rinse liquor refers to the rinse water. Each rinse is usually drained from the machine before the next rinse is applied, although alternative processes are known whereby the first rinse can be added to the machine without draining the wash liquor - draining and subsequent rinses can then follow.
- intermediate rinse means a rinse which is not the final rinse of the laundry process and the term “final rinse” means the last rinse in the series of rinses.
- a composition comprising a benefit agent, such as a rinse conditioner, is added to the final rinse only.
- a benefit agent such as a rinse conditioner
- the active agent is preferably present both in the main wash and preferably throughout the rinses, or in at least in one (preferably the first) of the rinses.
- the present invention is not concerned with those instances where the active agent is present only in the main wash, or is only present in the final rinse.
- an extended release composition is used in the main wash in the method of the invention.
- the active agent is entrapped, preferably encapsulated in an extended release matrix.
- the active agent is added by means of a dispensing device containing said active agent entrapped in a 'slow-release' formulation.
- the slow release formulation preferably comprises a carrier material for the active agent.
- the carrier material is at best sparingly soluble in the wash or rinse liquor.
- the extended release matrix may be any material which is capable of providing extended release of an active agent over an extended period of time.
- the further active agent is added from a composition which slowly releases the active agent, but is large enough to be retained between wash/rinse steps of the laundry process.
- the active agent can be suitably delivered by encapsulation in an extended release granule of a sufficient size (between 3 ⁇ m and 10mm) that it is retained in the drum during the wash and rinse steps of the laundry process.
- the further active agent is added from a composition which slowly releases the active agent, but is large enough to be retained between wash/rinse steps of the laundry process.
- the active agent may also be delivered in an extended release matrix used for multiple laundry processes (i.e. used for multiple wash/rinse cycles); it may alternatively be delivered by an automatic dosing system whereby the required amount is automatically added to each laundry process, or to each wash or rinse step of the laundry process.
- a polyalkylene glycol, preferably poly[ethylene glycol] (PEG), based carrier material is used in a preferred embodiment of the invention.
- the amount of the active agent within the PEG carrier is such that the concentration of transition metal sequestrant and dispersant present in the wash liquor or rinse liquor is from 0.001 g/L to 1.Og/L, preferably from 0.0015g/L to 0.5g/L
- One preferred dispensing device is a dispensing ball or 'shuttle', more preferably a dual or multi compartment dispensing device.
- the dual or multi-compartment dispensing device comprises the active agent entrapped on a carrier material with one or more separate compartments available for the incorporation of a solid or liquid detergent in a separate compartment of the device to the extended release active agent formulation.
- the dispensing device can be tailored for a single use, i.e. for a single wash with one or more rinse cycles.
- the dispensing device can be tailored for use on multiple occasions, i.e. numerous wash and rinse cycles.
- the dispensing device will preferably take the product form of an extended release dispensing device present in the main wash drum, tray or sump of the washing machine.
- the present invention may be put into effect by means of a so-called “smart shuttle".
- a so-called “smart shuttle” which may include means for measuring parameters of the liquor, release of materials occurs when predetermined conditions are met.
- a device of this general description is disclosed in US 2004/0088796.
- the Aqueous Liquor The Aqueous Liquor
- the aqueous composition (be it the main wash liquor, or a rinse liquor) comprises the active agent.
- the textile is contacted with the aqueous composition comprising the active agent in the main wash and further active agent is made available during a subsequent rinse step of the laundry process for contact with the white textile articles.
- the active agent may be simply the transition metal cation sequestrant and dispersant, or it may, in addition, comprise other beneficial components.
- the active agent is comprised in an aqueous composition as described above.
- This aqueous composition comprising the active agent is prepared by the dissolution or dispersion of the active agent in the wash or rinse liquor.
- the active agent Prior to said dissolution/dispersion, the active agent may exist in any suitable form.
- Preferred formats are that the active agent is:
- a) included in a composition for example a laundry detergent or rinse conditioner composition, which may be a powder, liquid, gel or tablet composition; b) encapsulated in a capsule or capsules, immobilised in a suitable carrier or matrix, for example in a slow release formulation; c) held on a support; or, d) simply used as the neat compound itself, with or without other components.
- a laundry detergent or rinse conditioner composition which may be a powder, liquid, gel or tablet composition
- encapsulated in a capsule or capsules immobilised in a suitable carrier or matrix, for example in a slow release formulation
- c) held on a support or, d) simply used as the neat compound itself, with or without other components.
- the active agent and further active agent can be added to the wash or rinse liquor manually, for example during hand washing or a semiautomatic washing process.
- manual addition include using a scoop or a jug to add a measured quantity of the active agent directly into the wash or into one or more rinse liquors.
- the scoop or jug may be calibrated.
- the active agent may be added to the wash or rinse liquor by means of automatic dosing by a washing machine with automatic dosing functionality.
- addition should be to every wash stage including the, or each, main wash and all the rinses. This may be accomplished by modification of the washing machine design such that the machine comprises specific dispensing means to ensure that materials are added to the water being supplied into the washing drum.
- washing machines are supposed to last for a number of years it is preferable to provide means to ensure that the present invention can be put into effect with an existing washing machine.
- the active agent in whichever form, may be contained in a dispensing device.
- the dispensing device may be suitable for use in the drum or the drawer of a washing machine. It may be attached to the interior of the drum, or the sump of the washing machine, or attached to the water inlet so as to come into contact with the water for the wash or rinse liquor before the water enters the washing machine. This may either be used for a single or a plurality of washes and in either case may be consumed entirely (such as a tablet or granular composition) or partially (such as a 'shuttle'). In the case of a dispensing device attached to the water inlet of the machine it is convenient that the device can be bypassed if the user wishes to employ a bleaching composition although this is not strictly necessary if a sufficient excess of bleach is present.
- contact with the further active agent means that the concentration of active agent in the aqueous composition is replenished or increased during the laundry process or is kept substantially constant throughout the process.
- the replenishment typically occurs when fresh water is taken into the washing process and comes into contact with the source of active agent thus causing dissolution of a quantity of the agent into the water.
- the active agent can have extended release into the liquor through all or part of the laundry process.
- the present invention does not rely on carry-over of already dissolved transition metal sequestrant or dispersant from the wash into subsequent stages of the laundry process.
- Contact with the further active agent means that a separate rinse-added composition comprising the mild reducing agent is added to a rinse step and contacted with the fabric.
- the active agent may be immobilised in a slow release matrix, immobilised in a slow release matrix, dissolution and/or dispersion into the liquor takes place when the water for a main wash or rinse is taken in by the machine and contacts the immobilised formulation.
- extended release is meant a means by which addition of the active agent to the wash or rinse liquor is allowed to progress in portions over time. This can be through an automatic dosing device either as part of the washing machine, or exterior to the washing machine.
- the means for extended release is through a device which allows for constant contact between the wash or rinse liquor and the extended release device. More preferred is a device which allows constant contact between a constant available surface-area of the active agent immobilised on a carrier material.
- the preferred embodiment of the product is formulated so that the active agent is dispensed from the slow release formulation in an amount such that the concentration of transition metal cation sequestrant and dispersant are independently maintained at a level of from 0.001 g/l to 1.Og/I preferably from 0.0015g/l to 0.5g/l.
