Definitions
- the present invention relates to a process of bleaching fabrics with a composition comprising a peroxy carboxylic acid.
- Detergent compositions suitable for laundry applications are well known in the art. It is also known that detergent compositions relying on hypochlorite as a bleaching agent can be preferred over oxygen bleaches, mainly for performance reasons, especially at lower temperatures. Typically used oxygen bleaches are the oxygen bleach precursors perborate or percarbonate that react with an activator species to produce hydrogen peroxide.
- hypochlorite bleaches there are some limitations to the convenience of hypochlorite bleaches.
- hypochlorite bleaching may cause yellowing and/or damage of the fabrics which are being bleached. This holds particularly true for synthetic fabrics and indeed there is a standing prejudice against using hypochlorite bleaches on synthetic fibers, as evidenced by warnings on labels of commercially available hypochlorite bleaches.
- fabrics made of or containing synthetic fibers are labeled by their manufacturers as non-bleachable.
- the manufacturer is therefore faced with achieving a balance between cleaning performance and fabric and/or colour damage.
- the Applicant has identified a bleaching agent, peroxy carboxylic acid, that is milder than hypochlorite, yet still provides improved cleaning performance versus the oxygen bleach precursor bleaching agents currently used in most fully formulated detergent compositions.
- Peroxy carboxylic acids are known in the art for example EP 435 379. However, despite the apparent suitability of this bleach, it has been found that cleaning performance is occasionally not sufficient to meet consumer expectations.
- the bleaching processes described herein provide effective bleaching performance and effective stain removal performance even when relatively short soaking time conditions are used, for example below 30 minutes, more preferably below 10 minutes and most preferably below 5 minutes. Furthermore, the bleaching processes described herein even provide effective bleaching performance and effective stain removal performance when soaking is carried out in cold water, for example 4°C.
- the present invention provides a process of bleaching fabrics that best fits the needs of today's consumers, i.e. a process of bleaching fabrics that provides effective bleaching and stain removal performance in reduced time periods and/or by using cold water.
- the laundry bleaching operations according to the present invention are safe to the fabrics per se and/or fabrics colours. Indeed, it has been surprisingly been found that when formulating the composition used in the salt and process as described herein, the safety (both fabric safety and colour safety) delivered to the fabrics bleached therewith according to the process of the present invention is improved as compared to formulating the same ingredients in a granular composition. Summary of the invention
- the present invention encompasses a process of bleaching a fabric comprising the steps of :
- the present invention encompasses a process of bleaching fabrics as described herein after.
- fabrics any types of fabrics including for example clothes, curtains, drapes, bed linens, bath linens, table cloths, sleeping bags, tents, upholstered furniture and the like.
- the process of bleaching fabrics herein is suitable for both natural fabrics and synthetic fabrics.
- natural fabrics it is meant fabrics made of cotton, viscose, linene, silk and/or wood.
- synthetic fabrics it is meant those made of synthetic fibers like polymeric fibers (polyamide, polyester, lycra® and elasthane®), and those made of both natural and synthetic fibers.
- the process of bleaching fabrics according to the present invention comprises the steps of:
- the fabrics are left in contact with the composition comprising peracid (in the so-called "soaking step") for a period of time sufficient to bleach the, fabrics.
- This period of time typically ranges from 1 minute to 24 hours, preferably from 3 minutes to 12 hours and more preferably from 4 minutes to 6 hours.
- the process of bleaching according to the present invention provides effective bleaching performance and effective stain removal performance even upon shorter soaking time, typically below 1 hour, preferably below 20 minutes and more preferably from 4 minutes to 15 minutes.
- the composition may be diluted with water at a dilution level of up to 500 times its weight, preferably from 5 to 200 times and more preferably from 10 to 80 times. Such dilution may occur for instance in hand laundry applications as well as by the other means such as in washing machine.

- the process of bleaching fabrics according to the present invention provides improved bleaching performance and improved overall stain removal performance, as compared to the same process where the bleaching composition used is a composition based on activated hydrogen peroxide at the same total level of bleaching agents. Also these benefits are obtained with the process of bleaching fabrics according to the present invention with short soaking time in both cold or hot aqueous baths. Indeed, effective bleaching performance is provided on a variety of bleachable soils, from hydrophobic to hydrophilic soils on both hydrophilic and hydrophobic fabrics. Effective bleaching performance herein also includes effective whiteness.

- washing may be conducted before or after the fabrics have been soaked in the bleaching composition according to the process of the present invention.
- the fabrics are preferably washed in a separate step from the process of the present invention to get optimum bleaching and stain removal performance.
- conducting the process herein and washing with a detergent composition in the same step may cause chemical interaction between the peracid and the conventional detergent ingredients typically present in a conventional detergent composition, i.e. enzymes, surfactants and the like and thus may reduce the bleaching performance and/or overall stain removal performance.

- the tensile strength in a fabric may be measured by stretching said fabric until it breaks.
- the force needed to break the fabric is the "Ultimate Tensile Stress” and may be measured with a stress-strain INSTRON ® machine available from INSTRON.
- the loss of tensile strength is the difference between the tensile strength of a fabric taken as a reference, e.g. a fabric which has not been bleached, and the tensile strength of the same fabric after having been bleached with a composition of the present invention.
- a tensile strength loss of zero means that no fabric damage is observed.
- the colour safety can be evaluated visually by comparing side by side fabrics soaked with a composition of the present invention and a reference composition. Differences and graduations in colour can be visually assessed and ranked according to Panel Score Units (PSU) using any suitable scale. PSU data can be handled statistically using conventional techniques. Alternatively, various types of optical apparatus and procedures can be used to assess the improvement in colour safety afforded by the present invention. For example when evaluating colour safety on fabrics measurements with Hunterlab colour Quest 45/0 apparatus can be used.
