Description

c3)   0.5 to 5 wt.% of a co-surfactant selected from the group consisting of alkoxylated C8-C18 fatty alcohols with a degree of alkoxylation of < 3, aliphatic C6-C14 alcohols, aromatic C6-C14 alcohols, aliphatic C6-C12 dialcohols, monoglycerides of C12-C18 fatty acids, monoglycerol ethers of C8-C18 fatty alcohols and mixtures thereof, preferably from the group consisting of alkoxylated C8-C18 fatty alcohols with a degree of alkoxylation of < 3.

[0034] The detergent preparation contains an organic solvent as a fifth essential component. The weight proportion of the organic solvent with respect to the total weight of the detergent preparation is preferably 7 to 20 wt.%, preferably 10 to 18 wt.%.

[0035] Preferred organic solvents are selected from the group of ethanol, n-propanol, i- propanol, butanols, glycol, propanediol, butanediol, methylpropanediol, glycerol, diglycol, propyl diglycol, butyl diglycol, hexylene glycol, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol propyl ether, ethylene glycol mono-n-butyl ether, diethylene glycol methyl ether, diethylene glycol ethyl ether, propylene glycol methyl ether, propylene glycol ethyl ether, propylene glycol propyl ether, dipropylene glycol mono methyl ether, dipropylene glycol mono ethyl ether, methoxytriglycol, ethoxytriglycol, butoxytriglycol, 1-butoxyethoxy-2-propanol, 3-methyl-3-methoxybutanol, propylene-glycol-t-butylether, di-n-octylether and mixtures thereof, preferably from the group of propanediol, glycerol and mixtures thereof.

[0036] The detergent preparation is preferably a low-water substance mixture. Detergent preparations of this kind which contain, with respect to the total weight thereof, less than 18 wt.%, preferably less than 15 wt.%, of water are preferred.

[0037] Essential for the development of the desired optical and rheological properties of the detergent preparation is the addition of 0.3 to 8 wt.%, preferably 0.4 to 6 wt.%, and in particular 0.5 to 4 wt.% of salt of a divalent cation (in each case with respect to the total weight of the detergent preparation).

[0038] Preferably, the use of salt of divalent cations is from the group of divalent metal cations, preferably of magnesium and calcium salts, preferably the magnesium and calcium salts, preferably from the group of magnesium chloride, magnesium sulfate, calcium chloride and calcium sulfate, particularly preferably from the group of magnesium chloride and calcium chloride, in particular calcium chloride.

[0039] Essential for the long-lasting fragrance release is the addition of the fragrance capsules in weight proportions of 0.01 to 1 wt.%. Preferably, the detergent preparations contain, with respect to their total weight, 0.01 to 0.7 wt.%, preferably 0.02 to 0.5 wt.% fragrance capsules.

[0040] Fragrance capsules are usually characterized by a fragrance-containing core and a layer or shell surrounding this core. The capsules known to a person skilled in the art can be used as fragrance capsules. Preferred group of fragrance capsules can be assigned to two groups: -     fragrance capsules are selected from the group of fragrance capsules containing melamine- urea-formaldehyde, fragrance capsules containing melamine-formaldehyde, fragrance capsules containing urea-formaldehyde; -     biopolymer-containing fragrance capsules, in particular from the group of protein-containing fragrance capsules and polysaccharide-containing fragrance capsules, in particular gelatincontaining fragrance capsules, chitosan-containing fragrance capsules, starch-containing fragrance capsules and alginate-containing fragrance capsules.

[0041] In a particularly preferred embodiment, the fragrance capsules comprise a core material and a barrier layer surrounding the core material as well as a stability layer arranged on the outer surface of the barrier layer, the stability layer comprising at least one biopolymer.

[0042] The detergent preparation is preferably free of organic opacifying agents. “Free of,” as used in this context, means that the corresponding component is present in the preparation in an amount of < 1 wt.%, preferably < 0.1 wt.%, even more preferably < 0.01 wt.%. In particular, a component of this kind is not deliberately added. The liquid, surfactant-containing detergent preferably contains in particular no styrene-acrylate copolymers (INCI: styrene / acrylates copolymer).

[0043] The detergent preparation may be free of enzyme preparations. These components are in particular not contained because they can adversely affect the turbidity and thus the appearance of the formulation. For example, detergent preparations which contain, with respect to the total weight thereof, less than 2 wt.%, preferably less than 1 wt.%, particularly preferably less than 0.1 wt.% and in particular no enzyme preparation are preferred.

[0044] The detergent preparation is also preferably free of phosphonates. “Free of,” as used in this context, means that the corresponding component is present in the preparation in an amount of less than 2 wt.%, preferably less than 1 wt.% and particularly preferably less than 0.1 wt.%. In particular, a component of this kind is not deliberately added. The liquid, surfactant-containing detergent preferably contains no phosphonate

[0045] In an alternative embodiment, the detergent preparation contains at least one optical brightener, preferably a stilbene-type optical brightener. This is contained in the detergent preparation, with respect to the total weight thereof, in an amount above 0 wt.%, but preferably in an amount below 1 wt.%, particularly preferably in an amount below 0.6 wt.%. Stilbene-type brighteners for use in detergent preparation are preferably selected from the group of triazinyl derivatives of 4,4’-diamino-2,2’- stilbenesulfonic acid, in particular DAS1 (disodium 4,4-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)amino]stilbene-2,2-disulfonate) and DSBP (disodium 4,4-bis(2-sulfostyryl)biphenyl).

[0046] Alternatively or in addition to the optical brightener, the detergent preparation may contain at least one red, blue or violet dye. This is contained in the detergent preparation, with respect to the total weight thereof, in an amount above 0 wt.%, but preferably in an amount below 0.1 wt.%, particularly preferably below 0.02 wt.%, for example between 0.001 and 0.01 wt.%. A dye of this kind is used, for example, for the purpose of masking a possible yellowish hue in the preparation.

[0054] As described at the outset, the described combination of active ingredients results in an advantageous product appearance while simultaneously providing a lasting fragrance effect and high physical stability of the dispersed fragrance capsules.

[0055] The detergent preparations preferably have a cloudy white appearance. The Nephelometric Turbidity Unit (NTU) is frequently used as an indication of transparency. It is a unit, used e.g. in water treatment, for measuring turbidity, e.g. in liquids. It is the unit of turbidity measured with a calibrated nephelometer. High NTU values are measured for clouded compositions, whereas low values are determined for clear compositions.

[0056] In absolute values, the detergent preparation preferably has a turbidity (HACH Turbidimeter 2100Q, 20 °C, 10 ml cuvette) above 60 NTU, preferably above 100 NTU and in particular above 400 NTU.
