Definitions
- This invention relates to fabric stain removal methods for ambient-active fat/oil based stains, particularly but not exclusively as a pre-treatment or direct application.
- aqueous substrate cleaning is performed at cold or ambient temperatures. These temperatures are a challenge for fat/oil stain removal technology which relies on water temperatures of 40 - 70 degrees. In the case of modern washing machines, stain removal mainly relies largely on the heating of water above ambient temperatures in the washing machine. This accounts for a large proportion of the laundry related greenhouse gas footprint which needs reducing for environmental reasons.
- the objective of the invention is the removal of fabric stains from stained fabric, where the fabric stains comprise fat/oil.
- the invention provides a method for removing a stain comprising fat/oil from a stained fabric, comprising the step of applying to the stain, a fabric stain removal composition comprising an arginine compound and a surfactant.
- the invention provides a method of the first aspect of the invention, wherein the step of applying the fabric stain removal composition is a pre-treatment step using a pre-treatment device, wherein the pre-treatment device comprises (i) a storage chamber storing said fabric stain removal composition and (ii) a dispenser for locally applying said fabric stain removal composition to a stain on a fabric.
- the invention provides use of arginine compound, preferably in combination with a surfactant, in the removal of oil/fat stains from a stained fabric, preferably in the removal of fat stains, at ambient temperatures.
- the removal of oil/fat stains at low temperatures is radically improved and so offers improved laundry cleaning in regions where ambient washing occurs out of habit or necessity. Improved washing performance at lower temperatures is generally desirable but increased low temperature performance may also help inhibit the adoption of hot water washing in these countries, a rising trend as standards of living increase and more people are able to afford washing machines.
- the invention provides stain removal performance of fat based soil and/or stains in an ambient temperature cleaning processes (with low temperature wash liquor) without serious consideration to the temperature sensitivity of ingredients during storage.
- the formulation can therefore be designed more freely, on the basis of other considerations.
- substrate includes fabric, and clothing and other surfaces such as cutlery, crockery and other domestic hard surfaces.
- arginine compound is intended to include any suitable arginine compound, including stereoisomeric and racemic forms, derivatives, and substituted derivative and mixtures thereof.
- ambient-active is intended to mean less that 25 degrees Celcius and preferably 22 degrees Celcius or less, more preferably 15 degrees or less but always greater than 1 degree Celcius and "active" means effective in achieving stain removal.
- stain removal is means removal as measured in terms of Remission units or a Remission index. For a visible (by the human eye) effect, effective stain removal is represented by remission equal to or greater than 2 Remission units and preferably greater or equal to 5 units.
- wt% means “% by weight”. Unless specified otherwise, all percentages mentioned herein are by weight calculated relative to the total composition.
- the stain may comprise oil or fat, preferably fat. However, it is often found that other biological material may be included in the stain.
- the method of the invention preferably comprises an aqueous washing process. Accordingly it is preferred that the method comprises the step of adding water to the composition to form an aqueous wash liquor
- the method comprises localised application of the composition to a stain or stained area of the fabric.
- the method may be pre-treatment method, and be followed by a subsequent aqueous washing step. Pre-treatment steps may take place without further addition of any water (beyond any contained in the composition).
- the pre-treatment process may comprise the step of soaking the substrate in an aqueous solution to which the treatment composition has been added.
- the second step of the method of the invention may be a 'main' wash and may be a manual washing process or a washing process in a washing machine.
- the second step may use any suitable detergent composition.
- this detergent composition comprises one or more surfactants and/or other functional ingredients, adjuncts etc. as described below.
- the method of the invention is less than 90 minutes in duration, more preferably less than 60 minutes and most preferably less than 30 minutes.
- the pre-treatment step is preferably less than 5 minutes, and more preferably less than 2 minutes.
- the pre-treatment device may be by any suitable device such as roll-on applicator or tube, sprays, aerosols, pastes, a pump-operated dispenser or the like.
- the pre-treatment device may comprise a scrubbing member having brush, bristles, tufts, projections, embossments etc or any combination thereof to further aid application of the detergent composition to a substrate.
- the treatment composition is ambient-active. Accordingly, the temperature of the wash liquor step of aqueous washing process is therefore less than 40 °C and preferably less than 30 °C and more preferably less than 25 °C and more preferably less than or equal to 22 °C further more preferably 15°C or less at all times during the washing but excluding drying. Encouraging low temperature wash liquor is advantageous environmentally and financially.
- the treatment composition of the invention and/or any detergent composition used subsequently may comprise any of the following ingredients.
- compositions may comprise enzymes.
