DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a physically stable liquid cleaning composition comprising a nonionic surfactant, a polymer and a specific amphoteric surfactant. These liquid compositions can be used for a variety of cleaning applications including washing, softening, carpet cleaning, dishwashing, furniture cleaning, especially hard surface cleaning, glass cleaning or toilet cleaning, oral / dental compositions and cosmetics. Can be used in applications.

BACKGROUND OF THE INVENTION Various liquid aqueous cleaning compositions have been disclosed in the art. For example, much of the focus on liquid cleaning compositions has been to provide excellent cleaning of various surfaces and soils. Thus, liquid cleaning compositions have been developed based on various cleaning / soil release components to improve overall cleaning performance. For example, co-pending European Patent Application No. 9778008.5 describes a re-stain prevention polymer (ie, a copolymer of N-vinylpyrrolidone and a monomer unsaturated with an alkylene or a mixture thereof) and a nonionic interface. A liquid aqueous cleaning composition comprising an active agent and particularly suitable for cleaning hard surfaces is disclosed.

However, a drawback associated with the formulation of such liquid aqueous cleaning compositions comprising at least one nonionic surfactant and a polymer such as a polyvinylpyrrolidone homopolymer or copolymer is that they are physically unstable. It tends to be. In fact, the presence of such polymers, such as polyvinylpyrrolidone homopolymers or copolymers, in liquid aqueous nonionic surfactant-containing compositions is dependent on the relative concentrations of nonionic surfactants and polymers, and more particularly, on non-ionic surfactants. Depending on the concentration of the ionic surfactant, a cloudy composition can result, even over extended periods of storage, typically several days, or even immediately after incorporation into the composition. In other words, the higher the concentration of the nonionic surfactant in the aqueous liquid composition, the higher the physical instability of the composition due to the addition of such a polymer thereto. Thus, this physical instability is particularly noticeable when concentrated compositions are needed (e.g., when the total concentration of nonionic surfactant is 6%).
% Or higher). More specifically, in these concentrated liquid aqueous compositions, the polymer tends to separate from the composition immediately after its intended incorporation, thereby resulting in polymer-rich and other non-ionic Although it is high in type surfactant, it becomes two separate transparent aqueous phases. This separable phase separation phenomenon is indicated in the scientific literature as "separable coacervation".

[0004] Thus, it is an object of the present invention to provide a liquid aqueous cleaning composition comprising at least one nonionic surfactant and a polymer, especially a so-called "concentrated" liquid cleaning liquid, exhibiting improved physical stability. To formulate the composition. It can be said that the physical stability of the liquid aqueous composition comprising at least one nonionic surfactant and a polymer is improved by adding to this composition a specific amphoteric surfactant as defined hereinafter. Currently found. In a preferred embodiment of the invention, the invention is an extended composition comprising at least one nonionic surfactant, a polymer and such an amphoteric surfactant at a level of 6% or more by weight of the total composition. Provide a concentrated liquid aqueous composition that is physically stable during storage.

An advantage of the present invention is that it can be used in the washing / washing of fibers or in embodiments of the invention where the composition according to the invention further comprises a bleaching agent, in addition to bleaching of fibers, domestic applications,
It is applicable to a wide range of washing operations, including dishwashing applications, carpet applications or even dental or cosmetic applications. fact,
The compositions herein may be used in both the neat and diluted state, for example at dilution levels up to 1: 400 (composition: water), with the surface (human skin and / or mouth) and limitations of the organism Not made of inorganic materials including fibers, clothing and carpets and made of various materials such as shiny and matte ceramic tiles, vinyl, waxless vinyl, linoleum, melamine, glass, plastic, plastic wood. It can be used to clean any surface, including hardened surfaces.

[0006] The compositions of the present invention are desirably applied for cleaning hard surfaces. For example, the composition of the present invention comprising a nonionic surfactant, an amphoteric surfactant and a homopolymer or copolymer of vinylpyrrolidone as a polymer may further comprise Alternatively, in a preferred embodiment of the invention comprising a mixture thereof, a particularly improved cleaning is provided. Advantageously, these desirable liquid cleaning compositions, when used to clean hard surfaces, provide both effective first and second cleaning capabilities.
More specifically, these cleaning powers, and especially the second cleaning powers, give the surfaces according to the invention a good luster and at the same time a typical oily stain such as kitchen oil and Obtained for various types of stains / soils, including other severe stains such as baked / sticky food residues typically found in the kitchen.

Another advantage of the compositions according to the invention consisting of nonionic surfactants, amphoteric surfactants and polymers as defined herein is that they are capable of imparting a good shine to the surface to be cleaned. That is. In fact, it is observed that the composition is washed with the composition of the present invention and subsequently has less traces of water and / or even the deposition of calcareous scales, for example, on surfaces which come into contact with water during the rinsing. Advantageously, the advantage of the radiance imparted to the surface persists even after several rinsing cycles, thus reducing the formation of water marks on the surface and / or the deposition of calcareous scale. It provides long lasting protection, and therefore a long lasting shining surface.

Xanthan gum and derivatives thereof are available, for example, from Kelco under the trade names Keltrol RD, Kelzan S or Kelzan T. Such polymers are desirable in the liquid compositions herein for various reasons due to the end use envisioned for these compositions. For example, vinylpyrrolidone homopolymers and copolymers have the advantage that when used typically for washing or washing, they act as polymers and / or discoloration inhibitors to reduce re-staining.

More particularly, such vinylpyrrolidone homopolymers and copolymers contribute to an effective second cleaning performance associated with the compositions herein when hard surfaces are first treated with them. Is desirable in compositions of the present invention suitable for cleaning hard surfaces. Without being limited by theory, it is generally the property that such polymers, such as vinylpyrrolidone homopolymers or copolymers, are absorbed by the hard surface initially treated by them in a manner that leaves a hygroscopic layer. It is presumed that it has indeed. The resulting hygroscopic layer attracts and retains ambient atmospheric water to more effectively reduce the adsorption of once treated soil and / or to facilitate removal of soil subsequently deposited thereon. Less work on removing stains during a second cleaning operation compared to a similar dirty hard surface initially treated with a similar composition without the aforementioned polymer (Ie, less rubbing and / or wiping and / or less chemical manipulation). An advantage of the composition of the present invention is that the initial cleaning power is also increased compared to a similar composition without the vinylpyrrolidone homopolymer or copolymer described above. Such polymers, such as the vinylpyrrolidone homopolymers and / or copolymers, polysaccharide polymers or mixtures thereof previously described herein, when present in a liquid cleaning composition according to the present invention, may be used in a composition according to the present invention. It has been found that it reduces or even prevents the deposition of calcareous scale and / or traces of water on such surfaces that have been initially washed with the object, thereby providing a long lasting gloss. Furthermore, the presence of such a polymer in the composition of the invention produces a smoother surface, which can be sensed by touching said surface.

Prolonged by the presence of said amphoteric surfactant in a given composition consisting of a non-ionic surfactant and a polymer compared to the time required to observe phase separation by a similar composition Is meant. In fact, the compositions according to the invention are physically stable, ie they do not undergo phase separation when stored at 20 C for 4 months, and more typically at 20 C for 6 months. Advantageously, the present invention provides for the addition of small amounts of amphoteric surfactants thereto, to nonionic surfactants (eg, at 6% and higher levels) and polymers (
(E.g., at a level of 0.4% or higher) allows the formation of physically stable concentrated aqueous liquid compositions. In fact, due to the lack of an amphoteric surfactant as defined herein, at these concentrations of nonionic surfactant and polymer in an aqueous medium, the polymer becomes nonionic surfactant in order to form a polymer-rich aqueous phase. It tends to separate from the surfactant and leave a separate aqueous phase rich in nonionic surfactants. This discrete phase separation can be detected visually with or without microscopy.

, Applied to a sponge, and used to clean the tiles with a Sheen scrub tester. The number of strokes required for 100% cleaning is recorded. A minimum of 6 repetitions can be performed for each result made in duplicate on the control with each dirty tile. The second diluted wash ability can be evaluated by the following test method:
According to the procedure detailed for the first wash, the tiles used in the further tests are used and directly re-soiled without further washing or rinsing first. Care is taken that the method of washing is used with the Sheen scrub tester to wash the same parts where the test composition was previously washed by them. 100
The number of strokes required for% cleaning is recorded. A minimum of 6 repetitions can be performed for each result made in duplicate on the control with each dirty tile. This recontamination and cleaning procedure can be repeated up to five times.

The test method for evaluating the washing ability of the stock solution is the same as described above, except that the test composition and the control are used undiluted, and the rinsing after washing is repeated with clean water. . This repetition of rinsing may be repeated up to five times prior to the second re-contamination process for cleaning performance evaluation. The end result of good gloss is good spreading of the liquid composition on the surface when the surface is treated and less formation of water marks and poor solubility in water when the water evaporates Due to low salt deposition. The ability of a composition to provide a "gloss" to the surface indicates the ability of the composition to leave no water marks after evaporation of the water. This can be assessed by human visual grading. In a suitable test method, two rectangular areas (10 cm x 4 cm) of a sink (made of either stainless steel or ceramic) are a composition according to the invention and a control composition, for example the same composition but Containing no polymer. Three grams of the composition are first poured on each surface to be treated and then wiped using a Spontex sponge (10 strokes). Each treated surface is then rinsed with 200 grams of tap water and left to dry. After the surfaces treated with the composition according to the invention and those treated with the control composition have dried, they are compared with one another and evaluated by visual grading to assess the difference in gloss. Evaluation is generally performed by applying a Panel Score Unit (PSU). In the persistent gloss test method, the test methods described above may be performed,
However, the repetition of rinsing and drying is repeated several times. Each time when both surfaces are dry they are compared with each other and evaluated by visual grading to see the difference in gloss. The assessment is generally made by applying a Panel Score Unit (PSU).
