Description

The The invention relates to a frost-resistant fabric softener containing a softening compound, an antifreeze compound, a perfume and an emulsifier. The invention further relates to the use a softener and a process for its preparation.

The Provision of frost-resistant softener, is by the consumer as of course naturally in such areas desired, in which the climatic conditions this require. It is a known problem that softener formulations, which are in the form of dispersions, often an unsatisfactory Have low temperature stability, that is that they are influenced by the cold, especially after storage not only thicken significantly at temperatures below 0 ° C, but also precipitations, irreversible gels (training of areas with extremely high viscosity within the Weichspülers) and / or phase separations, etc. show. As a result of such precipitations, gels or phase separations, which also represent a considerable aesthetic defect, lose the fabric softener to a very large extent Functionality and can no longer be appropriate be used. For example, the gels dissolve even when "warm" the fabric softener not more and a dosage and / or a dispersion during the rinsing process is no longer possible.

The problem of the lack of cold stability of fabric conditioners is in the WO 04/099354 A1 for example, by adding an antifreeze compound such as ethylene glycol, propylene glycol, diethylene glycol or dipropylene glycol.

The Adding an antifreeze compound is sufficient for stabilization the fabric softener against cold as long as the amount to perfume in the softener formulation not more than 0.5 wt .-% is. When increasing the Perfume quantity decreases the frost stability of the softener strong.

liquid Fabric softeners often contain so-called esterquats as softening agents Compounds in the form of solvent-containing dispersions be used. As a solvent is used for cost reasons frequently Isopropanol. However, it has been shown that softener with an antifreeze compound and a plasticizing esterquat compound, which was used as isopropanol dispersion, at room temperature or 40 ° C are often not stable on storage. Storage-stable fabric softener with Esterquats and antifreeze compound are becoming common only when using dipropylene glycol instead of isopropanol receive. Dipropylene glycol-containing dispersions of Esterquats are however, due to the higher commodity price of dipropylene glycol significantly more expensive than isopropanol-containing softener.

It Therefore, an object of the present invention is a cheap To provide fabric softener with high perfume content, over a wide temperature range and in particular is frost stable.

These The object is achieved by a fabric softener containing a softening compound, an antifreeze compound, a perfume in an amount of more than 0.5% by weight and an emulsifier by mixing a premix of the perfume and the Emulsifier with the other components of the softener.

It Surprisingly, it has been shown that when the perfume before adding to the remaining components of the softener mixed with an emulsifier, a frost-resistant fabric softener can be obtained with increased perfume content.

It it is preferred that the ratio of perfume to emulsifier in the premix between 3: 1 and 1: 3 and preferably between 2: 1 and 1: 2 is. Particularly preferred is the ratio Perfume to emulsifier in the premix at 1: 1.

It has been shown that at these mixing ratios particularly frost-stable fabric softener can be obtained.

Farther It is advantageous that the amount of softening compound 5 to 80% by weight, preferably 6 to 40% by weight, more preferably 7 to 20 wt .-% and particularly preferably 8 to 15 wt .-%, each based on the entire fabric softener is.

softener with these amounts of softening compound show a good conditioning effect on textiles treated with it.

Further it is preferred that the amount of antifreeze compound 5 and 50% by weight, more preferably between 10 and 35% by weight and most especially preferably between 15 and 30% by weight, based on the fabric softener, is.

softener with these amounts of antifreeze compounds show even at extreme low storage temperatures (-20 ° C) is sufficient Frost stability.

It it is preferred that the antifreeze compound is a polyol and indeed particularly preferred is a polyol which is selected from the group consisting of ethylene glycol, Propylene glycol, diethylene glycol, dipropylene glycol, glycerol, pentaerythritol, Hexylene glycol, glucose, sorbitol and / or sucrose is included.

polyols are effective antifreeze compounds and especially these polyols give the fabric softeners additionally good viscosity properties at "normal room temperature" (20 °) and at temperatures below 0 ° C.

Especially the preferred plasticizing compound is an alkylated, quaternary compound Ammonium compound used, wherein at least one alkyl chain is interrupted by an ester or amido group, as these compounds have good softening properties and biodegradable are.

Surprisingly It has been found that the emulsifier also has a stabilizing effect Influence on the storage stability of the fabric softener at room temperature or at 40 ° C. So can these softening compounds in the form of isopropanol-containing Dispersions are used without the storage stability the corresponding softener at room temperature or 40 ° C drops or is no longer sufficient.

It is advantageous as an emulsifier an alkoxylated fatty alcohol and / or to use an alkyl glycoside, since these inexpensive and effective Emulsifiers for the perfume are.

It it is particularly preferred that the alkoxylated fatty alcohol is a ethoxylated and / or propoxylated primary alcohol with 10 to 18 carbon atoms and on average 1 to 20 moles of alkylene oxide (AO), preferably 2.5 to 19 AO, per mole of alcohol. These Emulsifiers are in liquid form and can so easy, fast and efficient with the perfume to one Premix be processed.

It It is preferred that the perfume be in an amount larger 0.5 to 3 wt .-%, preferably in amounts of 0.75 to 2 wt .-% and extremely is preferably present in amounts of 1 to 1.5 wt .-%.

The The invention further relates to the use of the invention Fabric conditioner for conditioning textile fabrics.

The Invention also relates to a process for the preparation of a softener, containing a softening compound, an antifreeze compound, a perfume in an amount of more than 0.5% by weight and a Emulsifier, at first a premix of the perfume and the emulsifier and then with this the other constituents of the softener is mixed.

Due to their small molecular structure essential oils pass through the skin and / or the mucosa in the bloodstream and the tissue. On In this way they can influence the whole organism.

A Variety of essential oils can in the invention Fabric softeners are used. Suitable essential oils include, for example, oils from Abies Sibirica, Amyris Balsamifera, Anise (Illicium verum), Lemon balm (Melissa officinalis), Basil (Ocimum Basilicum), Piments Acris, Beesbalm (Monarda Didyma), bergamot (Citrus aurantium bergamis), birch (Betula aba), Bitter orange (Citrus aurantium amara), hibiscus, hundred-leaved Rose (Rosa Centifolia), Calendula officinalis, California nut (Torreya Californica), Camellia sinensis, Capsicum Frutescers oleoresin, Caraway (Carum Carvi), Cardamom (Elettaria Cardamomum), Cedarwood (Cedrus Atlantica), Chamaecyparis obtusa, Chamomile (Anthemis Nobilis), cinnamon (Cinnamomum cassia), lemongrass (Cymbopogon nardus), Clary sage (Salvia scarea), carnation (Eugenia caryophyllus), Coriander (Coriandrum sativum), coriander seeds, cyperus esculentus, Cypress (Cupressus sempervirens), Eucalyptus citriodora, Eucalyptus Globulus, Fennel (Foeniculum Vulgare), Gardenia Florida, Geranium Maculatum, Ginger (Zingiber officinale), Camelina (Camelina sativa), Grapefruit (Citrus grandis), hops (Humulus lupulus), Hypericum Perforatum, Hyptis suaveolens, indigo shrub (Dalea spinosa), jasmine (Jasminum officinale), Juniperus communis, Juniperus virginiana, Labdanum, Laurel Nobilis, Lavandin (Lavandula hybrida), Lavender (Lavandula angustifolia), Lemon (Citrus Medica Limonum), Lemongrass (Cymbopogon Schoenanthus), Leptospermum Scoparium, Lime (Citrus Aurantifolia), Linden (Tilia Cordata), Litsea Cubeba, Lovage (Levisticum officinale), Citrus Nobilis, Massoy bark, Real chamomile (Chamomilla recutita), Moroccan Chamomile, Musk Rose (Rosa Moschata), Myrrh (Commiphora Myrrh), myrtle (myrtus communis), picea excelsa, nutmeg (myristica Fragrans), Olax Dissitiflora, Olibanum, Opoponax, Orange (Citrus Aurantium dulcis), Palmarosa (Cymbopogon martini), parsley seeds (Carum Petroselinum), Passiflora (Passiflora Incarnata), Patchouli (Pogcstemon Cablin), Pelargonium Graveolens, pennyroyal (Mentha Pulegium), Peppermint (Mentha piperita), Pine (Pinus palustris), Pinus Pinea, Pinus Pumiho, Pinus Sylvestris, Rosemary (Rosmarinus Officinalis), rose, rosewood (Aniba Rosseodora), rue (Ruta Graveolens), sage (Salvia officinalis), Sambucus nigra, sandalwood (Santalum Album), Sandarak (Callitris Quadrivalvis), Sassafras Officinale, Sisymbrium Ino, Spearmint (Mentha viridis), Marjoram (Origanum marjoram), Violet (Viola odorata), wood tar, thuja occidentalis, thyme (Thymus vulgaris), Vetiveria zizanoides, Wild mint (Mentha arvensis), Ximenia americana, yarrow (Achilles millefolium), ylang ylang (Cananga Odorata) and mixtures thereof.

The Perfume is in a premix with an emulsifier in introduced the fabric softener. As an emulsifier can preferably nonionic surfactants such as alkoxylated Fatty alcohols, alkoxylated fatty acid alkyl esters, alkyl glycosides, Amine oxides, primary amines or secondary amines be used. Particularly preferred as emulsifiers alkoxylated fatty alcohols and / or alkyl glycosides used.

The alkoxylated fatty alcohols used are preferably ethoxylated and / or propoxylated primary alcohols having preferably 10 to 18 carbon atoms and an average of 1 to 20 moles of alkylene oxide (AO), preferably 2.5 to 19 AO, per mole of alcohol in which the alcohol radical is linear or preferably in the 2-position may be methyl branched or may contain linear and methyl-branched radicals in the mixture, as they are usually present in Oxoalkoholresten. In particular, however, alcohol ethoxylates with linear residues of alcohols of native origin having 12 to 18 carbon atoms, for example, coconut, palm, tallow or oleyl alcohol, and on average 2 to 8 ethylene oxide (EO) per mole of alcohol are preferred. The preferred ethoxylated alcohols include, for example, C _12-14 alcohols with 2.5 EO, 3 EO, 4 EO, 6 EO or 7 EO, C _9-11 alcohol with 7 EO, C _13-15 alcohols with 3 EO , 5 EO, 7 EO or 8 EO, C _12-18 alcohols with 3 EO, 5 EO or 7 EO, C _16-18 alcohols with 12 and mixtures of these, such as mixtures of C _12-14 -alcohol with 2 , 5 EO and C _12-18 -alcohol with 7 EO. The degrees of ethoxylation given represent statistical means which, for a particular product, may be an integer or a fractional number. Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE). Nonionic surfactants containing EO and PO groups together in the molecule can also be used according to the invention. Here, block copolymers with EO-PO block units or PO-EO block units can be used, but also EO-PO-EO copolymers or PO-EO-PO copolymers. Of course, it is also possible to use mixed alkoxylated nonionic surfactants in which EO and PO units are not distributed in blocks, but randomly. Such products are available by the simultaneous action of ethylene and propylene oxide on fatty alcohols.

Furthermore, end-capped, alkoxylated fatty alcohols without free OH groups can also be used as emulsifiers. An example includes a n-butyl end-capped C ₁₂ -C ₁₄ fatty alcohol with 10 EO (Dehypon LS 104 ex Cognis).

It It has been found that too high a degree of alkoxylation of Fatty alcohols, in particular a degree of alkoxylation greater 20 AO, does not cause sufficient frost stabilization.

In addition, other suitable emulsifiers also alkyl glycosides of the general formula RO (G) _x can be used in which R is a primary straight-chain or methyl-branched, especially in the 2-position methyl-branched aliphatic radical having 8 to 22, preferably 8 to 10 carbon atoms and G is the symbol which represents a glycose unit having 5 or 6 C atoms, preferably glucose.

The dissolution delay compared with conventional amorphous sodium silicates may have been caused in various ways, for example by surface treatment, compounding, compaction / densification or by overdrying. In the context of this invention, the term "amorphous" is also understood to mean "X-ray amorphous". This means that the silicates do not yield sharp X-ray reflections typical of crystalline substances in X-ray diffraction experiments, but at most one or more maxima of the scattered X-rays which have a width of several degrees of diffraction angle. However, it may well even lead to particularly good builder properties if the silicate particles provide blurred or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline regions of size 10 to a few hundred nm, with values of up to a maximum of 50 nm and in particular up to a maximum of 20 nm being preferred. Particularly preferred are compacted / compacted amorphous silicates, compounded amorphous silicates and overdried X-ray amorphous silicates.
