The technical field to which the invention relates.

The present invention relates to a stable soluble products with a single dose, which offer plenty of useful effect in the care of fabrics.

The level of technology

Currently, consumers want to use a product with improved care for fabrics that provides such benefits as improved softness, reduced creasing fabric, less mechanical damage during washing, less discoloration and less stalling/spasavanje. Cationic polymers known in the art for providing improved care for fabrics. There is therefore a strong need to add these polymers in liquid products with a single dose, which dissolve quickly and easily disperse in solution. However, recently it has been discovered that the addition of cationic polymers in a liquid product with a single dose leads to poor solubility, since cationic polymers can form complexes with anionic-charged water-soluble or dispersible film.

Accordingly, there remains a need for inclusion of such cationic polymers in liquid products with a single dose without affecting the solubility of the covering film.

The invention

In accordance with the present invented the eating we offer the product with a single dose, containing non-aqueous liquid composition comprising: a cationic polymer and a fatty acid or salt; non-aqueous liquid composition is enclosed within a water-soluble or dispersible film. The present invention also provides a method of obtaining products with a single dose, including the stage at which: pre-mixed cationic polymer with a fatty acid or salt with the formation of the premix cationic polymer/fatty acids; unite premix cationic polymer/fatty acid or salt with a non-aqueous liquid raw material with the formation of non-aqueous liquid composition and encapsulate non-aqueous liquid composition in a water-soluble or dispersible film.

Detailed description of the invention

The present invention relates to the use of cationic polymers to enhance beneficial effects when taking care of fabrics, in particular, how to provide these beneficial effects, including improved softness, easy to use unit dosage form. Articles in single dose in accordance with the present invention contain cationic polymer and a fatty acid or salt in the nonaqueous compositions encapsulated using a water-soluble or dispersible film. It has been unexpectedly found that the fatty acids and salts can prevent the complexation of cationic polim the RA with a water-soluble or dispersible film and so to prevent the reduction of the cationic polymer to the solubility of the film. I believe that the cationic polymer preferably forms complexes with fatty acid or salt and therefore cannot be associated with a film.

All percentages, ratios and proportions used in this application are given in mass percent encapsulated part of the articles in single doses (including such articles with multiple offices, if applicable) unless otherwise stated, i.e. not taking into account the mass of encapsulating material.

Articles in single dose:

Non-aqueous liquid composition containing a cationic polymer and a fatty acid or salt, is the product of a single dose containing at least one fluid-filled compartment. Fluid-filled separation refers to the separation of the products of a single dose containing liquid capable moistened tissue, such as clothing. These products contain a single dose in one easy to use form dosing: cationic cellulose polymer and cellulase enzyme contained in the nonaqueous composition encapsulated in a water soluble or dispersible film.

The product of a single dose may be of any form, shape and material that are acceptable for retaining the non-aqueous composition, i.e., not allowing the release of non-aqueous composition, and any additional component of the product unit is eskers to the contact of the product with a single dose with water. The exact implementation will depend, for example, the type and number of tracks in a product with a single dose, the number of branches in the product single dose and on the characteristics required for the product of a single dose kept, protected and delivered or released compositions or components.

The product of a single dose contains water-soluble or dispersible film that completely covers the at least one internal volume containing a non-aqueous composition. The product of a single dose may optionally contain additional compartments containing non-aqueous liquid and/or solid components. Alternatively, any additional solid component can be suspended in a fluid-filled compartment. The unit dosage form with multiple offices may be desirable for reasons such as:

separation of incompatible ingredients; or if it is desirable that the proportion of ingredients was released in the wash sooner or later.

It may be preferable to any unit that contains a liquid component, also contained an air bubble. The air bubble can have a capacity of less than 50%, preferably less than 40%, more preferably less than 30%, more preferably less than 20%, most preferably less than 10% of the volume of simple is the Christianity of the specified branch. Without being bound by theory, believe that the presence of the air bubble increases the portability of the product of a single dose to the movement of the liquid component within the compartment, thereby reducing the risk of leakage of the liquid component of the Department.

Water-soluble or dispersible film: water-Soluble or dispersible film typically has a solubility of at least 50%, preferably at least 75%, more preferably at least 95%. The method of determining the water solubility of the film, see Test methods. Water-soluble or dispersible film typically has the time of dissolution in less than 100 seconds, preferably less than 85 seconds, more preferably less than 75 seconds, most preferably less than 60 seconds. The method for determining the time of dissolution of the film, see Test methods.

For example, it may be preferred that the mixture of polymer present in the film, if one polymeric material has a higher solubility in water than the other polymeric material, and/or one polymer material has a higher mechanical strength than the other polymeric material. The use of copolymers and mixtures of polymers can have other benefits, including improved long-term stability of water-soluble or dispersible film to the wet ingredients. For example, US 6,787,512 discloses a copolymer film of polyvinyl alcohol containing a hydrolyzed copolymer of vinyl acetate and a second monomer sulfonic acid for improved resistance to detergent ingredients. An example of such a film is sold Monosol from Merrillville, Indiana, US, under the trademark: M. It may be preferable to use a mixture of polymers having different average molecular weight, for example a mixture of polyvinyl alcohol or its copolymer with an average molecular weight of from 10000 to 40000, and other polyvinyl alcohol or copolymer with an average molecular weight of from 100,000 to 300,000.

Also useful are polymeric compounds, for example, containing hydrolytically degradable and water-soluble polymer mixture, such as polylactide and polyvinyl alcohol, the floor is aimie by mixing polylactide and polyvinyl alcohol, typically containing from 1 to 35% by weight of polylactide and from 65% to 99% by weight of polyvinyl alcohol. The polymer present in the film can be either hydrolyzed from 60% to 98%, more preferably from 80% to 90%, to improve the dissolution/dispersion of the film material.

Columns and detectors are kept at 40°C. the Flow is set at 0.5 ml/min

To further reduce any interaction between the cationic polymer and a water-soluble or dispersible film non-aqueous liquid composition may contain a cationic polymer present in the form of particles. That is, the cationic polymer is not soluble in non-aqueous liquid composition or incompletely soluble in non-aqueous liquid composition. Acceptable forms particles include solid substances that are not completely water-containing and/or another solvent, but also include solids, partially gidratirovana and/or solvated. Partially hydrated or solvated particles are those which contain water and/or other solvent at levels that are insufficient, that is to cause complete solubilization of the particles. The advantage of partial hydration and/or solvation of the cationic polymer is that if you formed any agglomerates, they have low durability filtration of sediment and easy re-dispersing. Such hydrated or solvated particles generally contain from 0.5% to 50%, preferably from 1% to 20%, of water or solvent. While water is preferred, may be used any solvent capable of partial solvation of the cationic polymer. Particles of the cationic polymer is preferably as small as possible. Acceptable particles have an average diameter square D90 less than 300 microns, preferably less than 200 microns, more preferably less than 150 microns. The average diameter square D90 is defined as 90% of the particles having a size less than the area of a circle having a diameter D90. The method of measuring particle sizes, see Test methods.

Fatty acids

In addition to the cationic polymer non-aqueous composition of the product unit dose can contain from 0.2% to 40%, preferably from 0.5% to 30%, more preferably from 1% to 20%, by weight of fatty acids or its salts. Acceptable fatty acids and salts include having the formula:

R1COOM,

where R1 is a primary or secondary alkyl group of 4-30 carbon atoms, and M depict is to place a cation, hydrogen or other solubilizers cation. While acid (where M is a cation, hydrogen) is acceptable salt is preferred because it has a greater affinity for the cationic polymer. Therefore, fatty acid or salt, preferably chosen so that the pKa of the fatty acid or salt was less than the pH of the non-aqueous liquid composition. For this non-aqueous composition preferably has a pH of from 6 to 10.5, more preferably from 6.5 to 9, most preferably from 7 to 8.

The alkyl group represented by R1 may be a mixture of chains of different lengths and may be saturated or unsaturated, although it is preferable that at least two-thirds of the R1 groups had a chain length from 8 to 18 carbon atoms. Non-limiting examples of acceptable sources alkyl groups include fatty acids derived from coconut oil, solid fat, tall oil and oil palm kernels. To minimize the odor, however, it is often desirable to use initially saturated carboxylic acid. Solubilisers the cation M may be any cation which imparts water solubility to the product, although monovalent fragments in General preferred. Examples of acceptable solubilizing cations for use in the present invention include alkaline metals such as sodium and potassium, which are particularly preferred, and amines, that is their as triethanolamine, ammonium and morpholine. Although using a large part of the fatty acids should be included in the non-aqueous composition in neutralized salt form, it is often preferable to keep the amount of free fatty acids in the composition, as it can help maintain the viscosity of the nonaqueous composition.

The ability of the fatty acid or salt to prevent complexation of cationic polymer with a water-soluble or dispersible film depends on the level of fatty acids. If there is little or no fatty acid is present, the cationic polymer is fully capable of forming a complex with a water soluble or dispersible film. Such films have poor solubility, which leads to undesirable residues film on the fabric after washing. If non-aqueous liquid composition contains high levels of fatty acids, the film dissolves too easily and may even start to dissolve after contact with wet hands or surfaces.

Therefore, by regulating the levels of fatty acid solubility of the film can be adjusted. For example, to balance how easily soluble encapsulating film with sensitivity to leak due to contact with wet hands and surfaces. Additionally, using such means may be COI is used over a wide range of films for products with a single dose in accordance with the present invention, including lower cost, more soluble film. Such films are usually unacceptable, because they have a tendency to leak and education polluting residue after contact with wet hands and surfaces. However, due to the solubility of the film of the cationic polymer contained in the products of a single dose can be adjusted using the levels of fatty acids, and the problem of leakage and contamination due to contact with wet hands and surfaces can be removed.

EXAMPLES

Example 1 represents a non-aqueous liquid composition in accordance with the present invention containing cationic polymer (LK400) and fatty acid. Product single dose in accordance with the present invention formed as encapsulating non-aqueous liquid composition in a polyvinyl alcohol film (M, comes Monosol). Comparative example 1 and comparative example 2 both include the same level of cationic polymer, but do not contain fatty acid or salt. Comparative example 1 replaces fatty acid additional polyethylene glycol 200. Comparative example 2 includes a mixture of other anionic surfactants, nonionic surfactants, propane diol and a cationic polymer, but does not contain fatty acids. In all three examples, the cationic polymer is present in the form of particles.
