Description

"Textile treatment agent"

The present invention describes a composition for textile cleaning and care as well as its use and method using such a composition. In particular, the invention describes a composition which, in addition to further constituents, contains unsaturated C18-C24 fatty acids and unsaturated C20-C24 fatty alcohols.

The machine cleaning of textile fabrics is usually not only used to remove dirt and stains, but also for textile care. The care of textiles includes areas as diverse as scenting, coloring or finishing. Another aspect of textile care relates to influencing the perceptible surface softness of the textile, which is to be improved in the machine washing process by means of softening active ingredients.

Fabric softeners are generally added to the washing liquor in the last rinse of the machine wash in order to prevent the "dry rigidity" effect that occurs when the laundry is drying. The dry rigidity is caused by the formation of hydrogen bonds between the cellulose fibers. The fabric softening active ingredients lie on the fiber surface and weaken the interactions between the fibers. Due to the reduced stiffness of the item of laundry, the effort required when ironing is reduced and the wearing comfort is increased.

The group of fabric softening active ingredients includes, in particular, synthetic compounds from the groups of esterquat, cationic polymers and silicones.

The German patent DE 197 14 044 C1, for example, discloses fabric softener compositions based on a combination of esterquats and silicones.

The international patent application WO 2019/070838 A1 describes aqueous fabric softener compositions which contain a combination of a cationic polymer and a saturated fatty acid. The compositions can comprise, as an optional additive, unsaturated fatty acids.

The European patent application EP 2997959 A1 describes a cosmetic formulation which, in addition to an ester quat, can also contain unsaturated fatty alcohols.

Against this technical background, the object was to provide a textile treatment agent which, on the basis of natural raw materials, largely dispenses with synthetic active ingredients, achieves a fabric softening effect that the consumer can perceive. The textile treatment agent should be able to be packaged as a liquid, for example as a highly concentrated liquid, in particular as a surfactant-rich and water-poor formulation and for Incorporation into water-soluble packaged dosing units (detergent sachets) should be suitable. The textile treatment agent should be configurable as an independent fabric softener as well as as a component of a full-fledged textile detergent or a textile treatment additive, for example a fragrance composition or a colorant. Finally, in contrast to conventional fabric softeners, which are introduced into the washing liquor towards the end of the washing process, the textile treatment agent should already be metered into the washing liquor at the beginning of a washing process.

This problem was solved by combining specific unsaturated fatty acids and fatty alcohols in a surfactant-organic carrier.

A first subject matter of the claim is a composition for textile treatment comprising a) at least one unsaturated C18-C24 fatty acid; b) at least one unsaturated C20-C24 fatty alcohol; c) 5 to 80% by weight of surfactant and / or organic solvent.

In addition to a carrier based on surfactant and / or organic solvent, the composition according to the invention comprises at least one unsaturated C20-C24 fatty alcohol and at least one unsaturated C18-C24 fatty acid as further essential constituents.

The compositions can contain a single unsaturated C18-C24 fatty acid or else a mixture of different unsaturated C18-C24 fatty acids.

For the technical effect of the composition, in particular its fabric softening effect, it has proven to be advantageous if the proportion by weight of the unsaturated C18-C24 fatty acid in the total weight of the composition is 0.01 to 12% by weight, preferably 0.01 to 8% by weight. % and in particular 0.01 to 4% by weight.

Particularly preferred unsaturated C18-C24 fatty acids are selected from the group α-linolenic acid, stearidonic acid, eicosapentaenoic acid, docosahexaenoic acid, linoleic acid, palmitoleic acid, vaccenic acid, oleic acid, elaidic acid, gondoic acid ((11Z) -11-eicosenoic acid), gadoleic acid ((9Z) -9 - eicosenoic acid), erucic acid and nervonic acid.

The monounsaturated fatty acids have proven to be technically particularly effective C18-C24 fatty acids, with the co-9 fatty acids again being particularly preferred. Due to their softening effect, particularly preferred compositions are therefore characterized in that the unsaturated C18-C24 fatty acid is selected from the group of co-9 fatty acids, in particular from the group oleic acid, gondo acid and erucic acid, very particularly preferably from the group gondo acid. As stated above, the compositions can also contain mixtures of various unsaturated C18-C24 fatty acids. Due to their availability and their impressive fabric softening effect, the use of a mixture of oleic acid, gondo acid and erucic acid is particularly preferred.

A second essential component of the compositions is the at least one unsaturated C20-C24 fatty alcohol.

Again, the compositions can contain a single unsaturated C20-C24 fatty alcohol or else a mixture of different unsaturated C20-C24 fatty alcohols.

The proportion by weight of the unsaturated C20-C24 fatty alcohol in the total weight of the composition is preferably 0.01 to 12% by weight, preferably 0.01 to 8% by weight and in particular 0.01 to 4% by weight.

With regard to their fabric softening effect, the use of unsaturated C20-C24 fatty alcohols is particularly preferred and is selected from the group of monounsaturated fatty alcohols. The unsaturated C16-C22 fatty alcohol is particularly preferably selected from the group of palmitoleyl alcohol, oleyl alcohol, cis-11-eicosen-1-ol, and erucyl alcohol (cis-13-docosen-1-ol), very particularly preferably from the group cis-11 -Eicosen-1-ol and erucyl alcohol.

Due to their availability and their impressive fabric softening effect, the use of a mixture of cis-11-eicosen-1-ol and erucyl alcohol is particularly preferred.

The weight ratio of unsaturated C18-C24 fatty acid to unsaturated C20-C24 fatty alcohol is preferably 10: 1 to 1:10, more preferably 2: 1 to 1: 2 and in particular 5: 4 to 4: 5. Corresponding mixtures are available from sustainable sources and can be incorporated into the compositions in a simple manner.

In summary, a particularly preferred composition is characterized in that it contains a) mixtures of oleic acid, gondo acid and erucic acid, b) mixtures of cis-11-eicosen-1-ol and erucyl alcohol and c) 5 to 80% by weight of surfactant and / or contains organic solvent.

In addition to the unsaturated C18-C24 fatty acids and unsaturated C20-C24 fatty alcohols described above, the compositions can also contain their esters. The content of the corresponding esters in the compositions is due less to the desired fabric softening effect than to the origin of the unsaturated C18-C24 fatty acids and unsaturated C20-C24 fatty alcohols that are essential to the invention from sustainable sources.

In particular in all those cases in which the unsaturated C18-C24 fatty acid and / or the unsaturated C20-C24 fatty alcohol have not been produced synthetically but come from a natural source, the compositions can furthermore contain a vegetable oil. Preferred Compositions are characterized in that they contain a vegetable oil from the group of olive oil, pecan oil and jojoba oil, preferably from the group of jojoba oil.

In a particularly preferred embodiment, the composition contains an active ingredient mixture with the INCI name Hydrolyzed Jojoba Esters.

In summary, a particularly preferred composition is characterized in that it contains an active ingredient mixture with the INCI name Hydrolyzed Jojoba Esters and 5 to 80% by weight of surfactant and / or organic solvent.

The compositions contain 5 to 80% by weight of surfactant and / or organic solvent as a further essential component. It is particularly preferred if the composition contains surfactant and organic solvent.

The proportion by weight of the surfactant in the total weight of the composition is preferably 5 to 60% by weight, particularly preferably 10 to 50% by weight and in particular 25 to 50% by weight. These proportions by weight have proven to be particularly advantageous with regard to optimizing the cleaning action of the composition.
