- Advantageous embodiments of the detergent additive according to the invention are the subject of the dependent claims.
- the detergent additive according to the invention for improving the soft feel of textile products has at least the following components:
- the clay mineral may be both a natural and a synthetically produced clay.
- the terms clay and clay mineral are used synonymously herein. The construction of particularly advantageous clay minerals will be discussed in detail in the following sections. Of the _
- Clay minerals on the softness of textile fibers such as cotton
- the clay mineral due to its morphological properties, e.g. platelet-shaped aluminosilicates having a particle size diameter smaller than 2 microns, and its chemical-physical properties, such as the sliding behavior, deposited between and / or on the cotton fibers. This allows the fibers to slide better with each other, which leads to the improvement of the soft touch.

- the combination of clay mineral and PVP / VA copolymer improves according to one aspect of the invention, the deposition of the clay mineral on the textile fiber and thus increases the softness of the clay mineral.
- the detergent additive contains a surfactant.
- a surfactant Generally, those skilled in the art - -
- surfactants are charged (ionic surfactant) or uncharged (nonionic surfactant), surface-active organic compounds, wherein at least one hydrophilic molecular segment is soluble in polar solvents and poor or insoluble in nonpolar solvents. Furthermore, the surfactant contains at least one further hydrophobic molecular segment which is soluble in non-polar solvents and poorly or not soluble in polar solvents.
- a general definition of surfactants can also be found, for example, in Römpp Chemie-Lexikon, 9th edition, Georg Thieme Verlag Stuttgart, 1995, p. 4495-4499. Accordingly, surfactants are substances which reduce the interfacial tension and have a characteristic structure of at least one hydrophilic and one hydrophobic group.
- preferred clay minerals are smectite clay minerals. These clays have a structure of layered polysilicate units. Examples of smectic clay minerals are beidellite, hectorite, saponite, stevensite, nontronite and montmorillonite or bentonite.
- the surfactant is a nonionic surfactant.
- nonionic surfactants are hydrophobic hydrocarbon chains and hydrophilic ethylene oxide chains, propylene oxide chains or polyols.
- Nonlimiting examples of nonionic surfactants are fatty alcohol ethoxylates, polyethylene glycol ethers, alkyl glycosides, alkyl polyglycosides, sorbitan fatty acid esters, alkylphenyl ethoxylates, alkyl phosphine oxides and silicone surfactants.
- the PVP / VA copolymer is a copolymer containing only polyvinylpyrrolidone and polyvinyl acetate monomer units.
- the PVP / VA copolymer contains, in addition to the vinylpyrrolidone monomer units and the vinyl acetate monomer units, one or more other monomer units. These other monomer units may be contained in a proportion of 0.1 to 20 mol% in the PVP-VA copolymer. Suitable monomers are, for example, vinylimidazole, vinyl oxazolidone, vinyl propionate, methyl or ethyl (meth) acrylate.
- the PVP / VA copolymer generally has a vinyl pyrrolidone monomer unit content of about 1 to 99%.
- the PVP / VA copolymer has a proportion of vinyl acetate (VA) monomer units of at least about 20%, preferably at least 30%, more preferably at least 40%, more preferably at least 50%. It has thus been found that the improvement of the softness surprisingly increases with increasing content or proportion of the PVP / VA copolymer on VA. It is further preferred that the PVP / VA copolymer has a proportion of vinyl acetate monomer units of not more than about 90%, preferably not more than 80%, more preferably not more than 75%.
- the PVP / VA copolymer has a ratio of vinylpyrrolidone monomer units to vinyl acetate monomer units of between about 80:20 and 20:80, in particular between about 70:30 and 30:70.
- powdery PVP / VA copolymers are preferably used.
- Such powdery PVP / VA copolymers preferably have a ratio of vinylpyrrolidone monomer units to vinyl acetate monomer units of between about 70:30 and 60:40.
- PVP / VA copolymers which are processed in dissolved form, for example as an aqueous-alcoholic solution. These have a higher proportion of vinyl acetate monomers.
- An exemplary copolymer has a ratio of vinyl pyrrolidone monomer units to vinyl acetate monomer units of about 50:50.
- the PVP / VA comonomers preferably have a molecular weight in the range of 100,000 to 1,000,000 g / mol. Preferred ranges for the molecular weight are 300.00 - 900,000 g / mol and 500,000 to 800,000 g / mol.
- the detergent additive contains at least one carrageenan.
- the carrageenan both alone and in combination with the clay mineral, the surfactant and / or the PVP / VA copolymer, further improves the soft feel.
- Carrageenans are known to the person skilled in the art and it is possible to use all known carrageenans in the context of the present invention. They are the salts of linear galactose polysaccharides (of marine origin).
- ⁇ -carrageenan is a chain molecule composed of the other building blocks, ß-D-galactosido (1, 4) - ⁇ -D-galactose. These dimers are linked 1, 3-glycosidically.
- the primary alcohol group of ⁇ -D-galactose is esterified with sulfuric acid, and the hydroxy groups on C2 of both galactoses are also approximately 70% esterified with sulfuric acid.
- ⁇ -carrageenan thus has a sulphate content between 32 and 39%.
- K- and ⁇ -carrageenan are composed of the dimer carrabiose in which ⁇ -D-galactose is 1,4-glycosidically bound to ⁇ -D-3,6-anhydrogalactose. These dimers are linked by 1,3-glycosidic bonds to form a chain molecule.
- the difference between the two carrageenan types lies in the sulfation.
- the sulfate ester group is located at C-4 of galactose, the sulfate content fluctuates - -
- ⁇ -carrageenan the hydroxy group on the C-2 of the anhydrogalactose is additionally esterified with sulfuric acid.
- the sulphate content is between 28 and 35%.
- the average molecular weight of carrageenan is between 100,000 g / mol and 800,000 g / mol.

- the smectite clay mineral is a bentonite.
- bentonite consists for the most part of montmorillonite.
- the aluminosilicate montmorillonite is a three-layer material composed of two SiO 4 tetrahedral layers, between which there is an octahedral layer of predominantly aluminum ions. Isomorphous replacement of the trivalent aluminum ions by divalent ions, such as calcium or magnesium, produces a negative excess -
- the bentonite By exchanging these cations, the bentonite also acts as an ion exchanger. In addition to the different charges, cations such as Na + and Ca 2+ also significantly influence the swelling behavior of the bentonite. For example, embedded calcium ions have a narrower layered structure, while embedded sodium ions allow a more open stratification of the bentonite. In addition, the bentonite is able to store surfactants and thus to change its absorbency of textile fabric.
- the particle size of the clay mineral can have an influence on the improvement of the softness.
- the clay mineral is in particulate form, wherein at least 10 wt .-%, preferably at least 14 wt .-%, more preferably between about 10 and 50 wt .-% of the particles, more preferably between about 10 and 30 wt .-% of the particles have a particle size of less than about 600 ran.
- the particle sizes can be determined by standard methods such as the laser diffraction method using a Fritsch Particle Sizer Analysette 22 Economy (Fritsch, DE) according to the manufacturer's instructions, also with regard to sample pretreatment.
- the sample is homogenized in deionized water without addition of auxiliaries and sonicated for 5 minutes.
- the particle size determination is carried out as described in Jasmund / Lagaly, “Tonminerale and Tone", Steinkopf-Verlag Darmstadt (1993), page 16 and referenced therein Tributh & Lagaly (1986) "Preparation and identification of soil and Deposit Sites ", GIT laborz. Lab 30: 524 and 771.
- the above preferred particle sizes of the clay mineral are according to an alternative aspect of the present invention also independent of the use of the clay mineral in a detergent or detergent additive in combination with the PVP / VA copolymer, the surfactant and / or the carrageenan.
- the clay mineral is in activated form, i. Bi- or trivalent cations stored between the layers are exchanged for monovalent ions, such as sodium ions or protons.
- activated clay minerals are used in a manner known per se, e.g. made with soda. By exchanging the ions, the swelling capacity of the bentonite increases, which in turn influences the absorption properties.
- the clay mineral in particular the bentonite, is characterized in that at least 50%, preferably at least 60% and particularly preferably at least 80% of the cation exchange capacity (CEC) of monovalent cations, such as Na + , K + or NH 4 + , is formed.
- CEC cation exchange capacity
- the detergent additive contains at least 80 wt .-%, preferably at least 85 wt .-% clay mineral, such as bentonite.
- clay mineral such as bentonite.
- the high proportion of clay mineral, such as bentonite lowers the cost of the detergent additive compared to the surfactant or the other polymeric additives.
- the percentage data refer to a clay mineral, which still has a residual moisture content of about 10 wt .-%.
- the nonionic surfactant of the detergent additive is particularly preferably selected from the group of fatty alcohol ethoxylates and polyethylene glycol ethers.
- Both groups have the same basic structure of a linear or branched hydrophobic hydrocarbon chain (C x ) and a hydrophilic ethylene oxide chain (EO y ) with terminal alcohol group (s). These control both the efficiency, ie the required amount of surfactant, and the temperature sensitivity of the surfactant class.
- C x linear or branched hydrophobic hydrocarbon chain
- EO y hydrophilic ethylene oxide chain
- s terminal alcohol group

- more than 0.1 wt .-% no further improvement is usually observed, so that a higher proportion of fatty alcohol ethoxylate and / or polyethylene glycol ether from an economic point of view is no longer or at best limited makes sense. In most cases an addition of up to 0.06 wt .-% is sufficient to obtain the desired properties.
- the detergent additive based on the mass of clay mineral, more than 0.001 wt .-%, more preferably more than 0.01 wt .-%, particularly preferably more than 0.01 wt .-% polyvinylpyrrolidone polyvinyl acetate (PVP / VA ) Copolymer.

- the percentages refer to the solids content of the water glass.
- the modulus (SiO 2 : Na 2 O) of the water glass is preferably selected in the range from 2.4 to 3.5, more preferably from 2.6 to 3.4. It has surprisingly been found that with a water glass-based binding system, for example, granules are easier to loosen and thus show improved soft-grip effects.
- the use of water glass also avoids the formation of compact flakes of charged polymers (partially protonated copolymer PVP / VA) and oppositely charged clay fins, which on the one hand dissolve worse and on the other hand would also deposit on the fiber to a lesser extent. This effect can be circumvented by using an aqueous binder system based on a waterglass.
