Description

<Desc / Clms Page number 1>

 The present invention relates to a method of treating a carpet or carpet using a liquid composition. More particularly, the present invention relates to a method of treating a carpet or carpet comprising applying a liquid composition to said carpet or carpet using an electric spray device such that said composition provides a non-irritating property for the mucous membranes.

 Rugs or carpets made from synthetic or natural fibers and their blends are commonly used in homes and businesses as flooring. Various types of fibers can be used in the manufacture of carpets, including polyamide fibers, polyester fibers and wool, cotton and even silk fibers in the case of carpets.

 However, carpets or rugs, whether made of natural or synthetic fibers, are all prone to getting dirty and stained when in contact with many household items. Foods, fats, oils, beverages, especially coffee, tea and soft drinks, especially those containing acid dyes, can cause unsightly dark spots on carpets or carpets. fouling as a result of the presence of particles of dirt, clay, dust, that is to say particulate soils in general, coming into contact with the fibers of the carpet or carpet and adhering to those this. These last soils often appear in the form of a diffuse layer of dirt rather than in the form of spots and tend to accumulate, especially in so-called "zones of intense traffic", especially near doors as a result of heavy use of rugs or carpets in these areas.

 Liquid compositions for treating carpets and rugs are already known in the art, for example as described in WO 95/04127. To improve the cleaning performance of said liquid compositions, surfactants are added to carpet and carpet cleaning compositions as described, for example, in EP-A-0 794 244.

 The liquid carpet and carpet treatment compositions can be applied to a carpet or carpet of all kinds of

<Desc / Clms Page number 2>

 by using, for example, manual spraying devices, such as hand-activated trigger spray devices, pressurized aerosol sprays, such as pressurized aerosol cans, electric sprayers, etc. Large areas, such as carpets or rugs, are often difficult to treat with manual spray devices or pressurized aerosol sprays. The large area to be treated requires the application of a high quantity of liquid composition. Pressurized aerosol sprays convey only a limited quantity of product and have negative effects on the environment. Manual spraying devices require repeated manual operation of the device to apply the composition to the large area. This is laborious for the user and results in uneven distribution of the liquid composition on the treated surface. As a result, electric spray devices are a preferred form of application for liquid carpet and carpet treatment compositions. Electric spray devices suitable for use in carpet and carpet treatment applications are known in the art, for example, as described in the pending patent application PCT / US99 / 07347.

 However, liquid carpet and carpet treatment compositions comprising a surfactant applied to a carpet or carpet using an electric spray device may cause irritation of the mucous membranes of the user of said spray device or other persons standing near where the composition is sprayed on the carpet or carpet. During the application of the liquid composition, the electric spray device forms a fine spray of droplets of said composition. This fine spray of droplets includes droplets that are small enough to form an aerosol or mist of droplets. This aerosol remains at least partially suspended in the air for a limited period of time and can therefore be inhaled by the user or those which are very close. When the inhaled composition comprises a surfactant, it has been found that these compositions may cause irritation of the mucous membranes, for example, in the nose, mouth, throat or eyes.

 The object of the present invention therefore lies in a method of treating a carpet or carpet comprising the application of a liquid composition on the carpet or carpet using an electric spray device so that the user or persons who are nearby are not affected by mucosal irritation.

 Furthermore, an object of the invention is a method of treating a carpet or carpet which provides excellent overall cleaning performance on various types of stains, including particulate stains, grease stains, bleach stains and / or enzymatic stains.

 It has now been found that the above objects can be achieved by a method of treating a carpet or carpet according to the present invention.

 An advantage of the carpet and carpet treatment method according to the present invention is that said method provides a safe, easy and quick way for the user to clean a carpet or carpet, while also providing excellent overall cleaning performance. .

 More preferably, the carpet and carpet treatment method of the present invention provides excellent cleaning performance when used both for cleaning the entire carpet or carpet or for localized stains on the carpet or carpet.

 Advantageously, excellent cleaning performance is achieved on various types of stains and soiling, including enzymatic stains as well as particulate stains and / or grease stains, particularly in so-called "areas of heavy traffic. "heavily soiled.

 Another advantage of the present invention is that the carpet and carpet treatment method of the present application can be applied to all types of carpet and carpets, particularly those consisting of delicate natural fibers. The present invention is also suitable for use in cleaning textiles and wear-resistant fabrics, for example, upholstery, carpets, curtains.

 Yet another advantage of the carpet and carpet treatment method and compositions of the present invention is that they can be applied directly to the carpet or carpet without causing

<Desc / Clms Page number 4>

 damage. In particular, the compositions used in the present process are safe for all known types of carpet and carpet dyes, even the well-known particularly sensitive natural dyes.

 It is known that certain surfactants have the advantage of low irritation of the skin, eyes and / or mucous membranes. For example, EP-A-0 396 340, JP-A-07197079 and GB 2 236 321 disclose compositions comprising sulfosuccinate surfactants, wherein said compositions have the advantage of low skin irritation , eyes and / or mucous membranes. However, no spray application is described.

 DE-OS-21 16 147 discloses a sprayable carpet and carpet cleaning shampoo comprising a specific sulfosuccinamate surfactant, sodium lauryl sulfate and a specific sulfosuccinate surfactant. Moreover, said carpet and carpet cleaning shampoo offers the advantage of a lack of irritation of the mucous membranes due to the presence of the surfactant system.

However, carpet and carpet cleaning compositions applied to the carpet or carpet are not disclosed using an electric spray device.

 The present invention provides a method of treating a carpet or carpet comprising applying a liquid composition to said carpet or carpet using an electric spray device, wherein said composition comprises an anionic surfactant not an irritant judged to be non-irritating to the mucosa as measured in a surfactant solution at 5% active ingredient using the Draize test method.

<Desc / Clms Page number 7>

 much better still less than 500 micrometers and most preferably 350 to 10 micrometers.

 By "mean diameter" D (v, 0.9) less than 1500 micrometers "for a droplet size distribution, it is meant that 90% of the distributed droplet spray (expressed as a volume unit) has a lower droplet diameter. At 1500 micrometers, for example, a D (v, 0.9) of less than 1500 micrometers indicates that 90% of the total volume sprayed is dispensed with droplets having a diameter of less than 1500 micrometers.

The particle size distribution of a droplet spray can be determined by following the procedure detailed below
Appropriate test equipment is the Malvern Mastersizer S LongBed with a 1000 mm lens and a maximum particle size range of 3,475 micrometers. The Malvern Mastersizer S LongBed offers an opening of 21 cm (between its lenses) to receive the sprayed flow. In all measurements made on Malvern, the surface of the lenses must remain free of contamination by spraying. In this mounting procedure, the distance from the laser sprayer opening is set at 8 cm to minimize lens contamination. At a distance of 8 cm, the spray is directed towards the laser beam to center the laser on the spray cone. At least three measurements must be made for each pulverized composition in order to determine the particle size distribution of the droplet spray. The electric spray devices that can be used in the test according to the present invention are preferably constituted by a battery operated system. If this battery system is used, a "complete load test" is carried out "Full load test" here means that the current is kept constant by connecting the battery sprayer to a direct current of 3.9 V from an external power source to ensure a constant spray force.

The Draize test method (Draize, JH, Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics, US Food and Drug Administration, Topeka, Kansas, 1959) is used to test ingredients (such as surfactants) in foods, drugs and / or cosmetics to determine their irritation properties with respect to skin, eyes, mucous membranes, etc.
A typical test according to the Draize test method involves between six and nine rabbits. Rabbits are traditionally used because of their size and convenience of use. A predetermined amount (for example 0.1 ml) and a predetermined concentration (for example a solution of surfactant with 5% of active ingredient, preferably a surfactant solution containing 10% of active ingredient, better still a solution of surfactant; at 20% active ingredient) of the test substance are instilled, placed or sprayed into the lower eyelid of one eye of each rabbit, the untreated eye acting as a control. Damage to the eyes is visually calibrated by an expert who estimates the level of irritation (eg taking into account redness) at intervals of 1, 24, 48, 72 and 168 hours after exposure and subjectively determines a value of irritation to the test substance The assessment is based on the degree of redness of the cornea and the inflammation of the iris and conjunctiva The degree of total irritation is presented in the form of a scale numbered from 0 to
110, where 110 denotes a high level of irritation. A score between 0 and 10 is required to consider a chemical as "non-irritating", that is, so that the substance (for example the surfactant) is "judged" non-irritating to the mucous membranes. A rating between 11 and 25 defines a slightly irritating chemical. A score between 26 and 56 defines the chemical as moderately irritating. A score between 57 and 110 defines the chemical as a serious irritant
