- impregnating agents frequently use fluorocarbon resins and / or silicones (also fluorinated) as impregnating active ingredients which can be prepared both as aqueous products and also as solvent-based products. Depending on the field of application and form of application, these known agents are structured differently.
- Non-fluorinated silicones usually have a lower impregnating effect compared to fluorocarbon resins and fluorinated silicones. Often they have only a water-repellent effect and only rarely a small oil-repellent effect.
- the invention has for its object to provide a composition for impregnating and / or care products, on the one hand has a good water-repellent effect and on the other hand, as environmentally friendly as possible. Furthermore, the composition should have a good oil and dirt repellent effect.

- a so-called cationic polymer Surprisingly, it has been shown that the impregnation effect of such a composition is substantially better than the sum of the impregnating effects of the individual constituents.
- impregnating agents include, among others, fluorocarbon resins and silicones (siloxanes / silanes / silicone resins, also fluorinated).
- Cationic polymers can be obtained by incorporation of nitrogen-containing basic groups into synthetic or natural macromolecules.
- Examples of such cationic polymers are:
- Polyalkyleneimines such as polyethyleneimine
- Polyvinylamine such as polyvinylammonium chloride, poly-diallyldimethylammonium chloride
- Polyamides or polypeptides of predominantly basic amino acids (lysine, arginine, histidine,
- Cationic polymers further include chitosan and its derivatives. If more deacetylated 2-amino-2-deoxy-.beta.-D-glucopyranose units are present as acetylated in the naturally occurring chitin in the total molecule, this is called chitosan. The degree of the resulting deacetylation may vary.
- chitosan in acidic solution is a polycation with a high charge density.

- cationic biopolymers such as polyamides or polypeptides of predominantly basic amino acids (polylysine, polyarginine, polyhistidine, polycitrulin and their heteropolymers) are preferably used for the compositions according to the invention.
- cationic plastic dispersions such.
- the cationic polymers also include other basicly functionalized plastic dispersions.
- a non-fluorinated siloxane such as aminosiloxane, amino-amido-siloxane, alkyl-aminosiloxane, alkyl-amido-aminosiloxane or polyether-functionalized siloxane in combination with a cationic polymer is preferably used.
- the known impregnating active ingredient may be a functionalized siloxane of the type aminoalkyl-polydimethylsiloxane, amidoaminoalkyl-polydimethylsiloxane, alkyl-
- impregnating agents are cationic, z. B. amino-functionalized fluoroacrylate resins for the synergistic effect with a cationic polymer and fluorinated silicones (also largely functionalized).
- the known impregnating agent may be a fluorocarbon resin of the fluoroalkylated acrylate copolymer type or fluoroalkyl-modified polyurethanes (of the polyester and polycarbonate type) or fluoroalkylated polysulfonamides or a fluorinated silicone of the fluoroalkyl-aminoalkyl-polydimethylsiloxane or fluoroalkyl type.
- a single one of the above known impregnating agents can be combined with one or more of the cationic polymers or a single cationic polymer with one or more of the known impregnating agents, as well as several known impregnating agents can be combined with several of the cationic polymers.
- the synergistic impregnation enhancement occurs in the presence of relatively extreme concentration ratios of the components.
- concentration ratio of known impregnating agent to cationic polymer may be about 20: 1.
- the impregnation enhancing effect also remains with an excess of the cationic polymer, e.g. obtained at a ratio of about 1:20.
- a cationic polymer can be added to a known impregnating agent in order to improve the impregnating effect of the impregnating agent.
- a small proportion of cationic polymer can be used in particular in conjunction with a substantially reduced proportion of known impregnating active to achieve an at least the same impregnating effect as can be achieved by the known impregnating active ingredient alone in its usual concentration. This makes it possible, the proportion z.
- silicone siloxane / silane / silicone resin
- fluorocarbon resin or fluorinated silicone in an impregnating low, without a loss of impregnating Effect against a higher proportion of these impregnating agents without the presence of a cationic polymer occurs.
- a cationic polymer such as chitosan, functionalized polyacrylate or functionalized polyurethane does not entail any of the problems of (eco) toxicological properties known from conventional impregnating agents, it is advantageous, owing to the synergistic effect, to increase the proportion of an impregnating active ingredient which is problematic in terms of its ecological properties.
- fluorocarbon resin or fluorinated silicone in an impregnating and / or conditioning agent wherein an overall impregnating effect is achieved in connection with a cationic polymer, which is otherwise only by a high proportion of the less environmentally acceptable active substance such. Fluorocarbon resin or fluorinated silicone in the impregnating or care agent would be achieved.

- a more compatible active ingredient such as, for example, because of its bioaccumulation problematic agent such as fluorocarbon resin in an impregnating agent by the synergistic effect of the invention.
- aminosiloxane because the impregnation effect by the cationic polymer in combination with aminosiloxane gives an overall impregnation, which was previously achieved with fluorocarbon resin alone.
- Another advantage of the synergistic effect according to the invention is that even the proportion of non-fluorinated siloxane in an impregnating agent according to the invention can be reduced or kept low. Since siloxane is not readily biodegradable, a small amount in an impregnant is advantageous for environmental reasons.
- the total active ingredient content (dry) of an inventive impregnating agent based on non-fluorinated silicones may be from about 0.1 to about 60% by weight, preferably from 0.3 to 40% and in particular from 1 to 20%.

- the remainder up to 100% may include water and / or solvents as well as additives.
- a preferred range of the total active ingredient content is up to about 10.0%.
- the ratio of non-fluorinated cationic polymer silicone may vary between about 20: 1 and 1:20 and preferably between 10: 1 and 1:10, in particular between 10: 1 and 1:10 and in particular between 5: 1 and 1: 5. Ratio Examples are 0.5: 1, 2.5: 1 and 3.5: 1, with 0.7, 1.2, 1.7, 2.4 and 3.4: 1 embodiments given below.
- the total active ingredient content (dry) of an impregnating agent based on fluorocarbon resin or fluorinated silicones according to the invention with a cationic polymer is usually lower than with non-fluorinated silicone.
- the total active ingredient content may be about 0.1 to about 40 wt%, preferably 0.3 to 25% and 0.5 to 10%.
- a practical embodiment with fluorocarbon resin and chitosan is reported with a total active ingredient content of 0.56%.
- the ratio of fluorocarbon resin or fluorinated silicone as classic impregnating agents and the cationic polymer may vary in an impregnating agent according to the invention depending on the desired degree of reduction of classical impregnating active strength. For example, it is possible to reduce the concentration of a fluorocarbon resin by 60% without loss of impregnating effect, if instead a suitable cationic polymer is added to the impregnating agent and the concentration ratio (weight ratios) of impregnating agent to cationic polymer of 0.1: 1, preferably 0, 2: 1 is not exceeded. A practical embodiment is represented with a ratio of 0.12: 1. Overall, a ratio in the range of 0.05: 1 to 0.3: 1 can be provided.
- the proportion of cationic polymer is always higher than that of fluorocarbon resin or fluorinated silicone, while when using non-fluorinated silicone, the level of silicone may also be higher than that of cationic polymer.
- a composition according to the invention also comprises solvent-based compositions.
- siloxane is used in synergistic composition with chitosan, preferably as a microemulsion in water.
- An impregnating agent according to the invention can also be present as a gel or paste.
- Water-soluble or water-dispersible impregnating agents can be used to form water- and oil-repellent effects, for. B. be used on floor coverings.
- the substances penetrate into absorbent materials such as e.g. Wood, stone, cork superficially and reduce the surface energy of the substrates so strong that the wetting ability of the surface is greatly reduced by liquids. This results in an increased contact angle of a water drop on the substrate surface. Furthermore, the take-up speed of such treated surfaces is greatly reduced. In this case, almost no or only a weak film formation often occurs on the substrate.
- This liquid repellency makes it possible to protect moisture-sensitive and absorbent floor coverings from moisture damage or the ingress of liquid dirt by treatment with these impregnating / care products.
- each of chitosan having a degree of deacetylation of 95% and a molecular weight of 300,000 to 500,000 g / mol (Da) is used.
