EP3472289B1 - Concentrated liquid detergents containing polymers - Google Patents

Description

The present application is aimed at highly concentrated liquid detergents with surfactant contents of 30% by weight and more, which at the same time contain polymers in concentrations of 2% by weight or more and show optimized product stability by having a specially adapted surfactant system. Methods for washing textiles using the detergents described and their use are also recorded.

Liquid detergents are well known in the art and have become increasingly popular with consumers in recent years because they offer a number of advantages over solid detergents. These include, among other things, easier dosing, addition and dissolution in the washing liquor. In addition, they are perceived as safer and less aggressive towards the textiles and the environment. Especially for washing colored textiles, they have gained more and more popularity since their market launch.

There is a general trend on the market towards more highly concentrated liquid detergents, as these are associated with lower use of resources, which is due in particular to the lower transport weight and smaller bottle size. In addition, such highly concentrated agents are preferred by consumers because they take up little storage space in the household.

Although such compositions are advantageous from the point of view of handling and consumer acceptance, the known compositions suffer from disadvantages with regard to their stability, especially with longer storage times. These disadvantages are further intensified by the trend towards more highly concentrated products. For highly concentrated liquid detergents, the challenge is to accommodate more of the necessary performers (e.g. surfactants, polymers, enzymes, complexing agents, perfume, optical brighteners) in a smaller volume of liquid.

In order to achieve good washing performance from the consumer's point of view, polymer components are increasingly being used in modern liquid detergents. These are often essentially nonionic or anionic polymers of different functionality. Important groups are the so-called soil release polymers (soil-releasing polymers), the dye transfer inhibitors (DTIs), antiredeposition agents and polymeric dispersants. A particular challenge is to ensure stable incorporation of the polymers, since the compatibility of the polymer ingredients in a liquid formulation decreases with increasing surfactant concentration. As a result, turbidity, sedimentation or even phase separations occur. These not only affect the aesthetic appearance of the formulation, but also adversely affect the washing performance.

In DE 4344357 A1 describes liquid aqueous detergents and cleaning agents which contain 15 to 35% by weight of nonionic surfactants, preferably ethoxylated fatty alcohols and alkyl polyglycosides, and 0.01 to 5% by weight of a soil-releasing polymer.

US5962398 teaches isotropic liquid detergents containing 22 to 50% by weight anionic and 10 to 63% by weight nonionic surfactants and an anionic polyacrylic acid polymer which serves as an anti-redeposition agent.

There is therefore a need for improved, highly concentrated liquid detergent formulations which, with regard to the problems mentioned, have improved properties, i.e. in particular allow relatively large amounts of polymeric constituents to be formulated in a stable manner.

Surprisingly, it has now been found that the above-mentioned disadvantages of highly concentrated liquid detergents, i.e. detergents with surfactant contents of 30% by weight or more, can be overcome by using a special surfactant combination that enables stable formulation of polymeric components in amounts of 2 wt% or more allowed.

In a first aspect, the present invention therefore relates to a liquid detergent with a surfactant concentration of ≥30% by weight based on the total weight of the detergent, preferably in the range from 30 to 45% by weight, more preferably 32 to 38% by weight, and a concentration of polymeric components of ≥2% by weight based on the total weight of the agent, preferably 2 to 10% by weight, more preferably 3 to 5% by weight, characterized in that the agent contains a surfactant system which nonionic surfactants in an amount of 5 to 20% by weight based on the total weight of the agent, preferably 8 to 15% by weight, the nonionic surfactants comprising at least one alkyl ether and at least one alkyl (poly)glycoside, the weight ratio of alkyl ether to alkyl (poly)glycoside is 1:2 to 5:1, preferably 1:1 to 3:1, where the at least one alkyl ether is a fatty alcohol alkoxylate.

In a further aspect, the present invention relates to the use of a liquid detergent according to the invention for washing textiles.

In a further aspect, the present invention relates to a method for cleaning textiles, characterized in that a liquid detergent according to the invention is used in at least one method step.

These and other aspects, features and advantages of the invention will become apparent to those skilled in the art from a study of the following detailed description and claims. Thereby can any feature of one aspect of the invention may be employed in any other aspect of the invention. Furthermore, it should be understood that the examples contained herein are intended to describe and illustrate the invention, but not to limit it, and in particular the invention is not limited to these examples. Unless otherwise stated, all percentages are by weight based on the total weight of the agent/composition. Numerical ranges given in the format "from x to y" include the stated values. Where multiple preferred numeric ranges are given in this format, it is understood that any ranges resulting from the combination of the different endpoints are also included.

"At least one" as used herein refers to 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. In the context of components of the compositions described herein, this statement does not refer to the absolute amount of molecules but to the type of component. "At least one anionic surfactant" thus means, for example, one or more different anionic surfactants, i.e. one or more different types of anionic surfactants. Together with quantities, the quantities refer to the total quantity of the type of ingredient referred to.

"About", "approx." or "approximately" as used herein in relation to a numerical value refers to the corresponding numerical value ±10%, preferably ±5%.

The detergents described herein can be detergents for fabrics or natural fibers. The detergents within the scope of the invention also include washing aids which are metered into the actual detergent in manual or machine laundry in order to achieve a further effect or to enhance an effect. Furthermore, detergents within the scope of the invention also include textile pre- and post-treatment agents, i.e. those agents with which the item of laundry is brought into contact before the actual wash, for example to loosen stubborn dirt, and also such agents in a step downstream of the actual textile wash give the laundry other desirable properties such as a pleasant feel, crease resistance or low static charge. The latter means include fabric softeners. In preferred embodiments, however, it is a textile detergent.

The at least one enzyme that is present in a washing or cleaning agent supports the cleaning performance of the agent on specific soiling or stains. An agent according to the invention particularly preferably contains a number of enzymes, it being possible for the enzymes to belong to the same or different enzyme classes. The enzymes particularly preferably show synergistic effects with regard to their action on specific soiling or stains, i.e. the enzymes contained in the composition support each other in their cleaning performance.

In addition, the detergent can contain other ingredients that further improve the performance and/or aesthetic properties of the detergent. In the context of the present invention, the detergent preferably additionally contains one or more substances from the group of builders/complexing agents, bleaches, electrolytes, perfumes, perfume carriers, fluorescent agents, dyes, hydrotropes, foam inhibitors, silicone oils, graying inhibitors, shrinkage inhibitors, anti-crease agents, antimicrobial agents, germicides , fungicides, antioxidants, preservatives, corrosion inhibitors, antistatic agents, bittering agents, ironing aids, repellents and impregnating agents, swelling and non-slip agents, softening components, pH adjusters and UV absorbers.

Due to their superior solubility, the short-chain polyacrylates which have molar masses from 1000 to 10,000 g/mol, and particularly preferably from 1000 to 5000 g/mol, can in turn be preferred from this group.

Also suitable are copolymeric polycarboxylates, in particular those of acrylic acid with methacrylic acid and acrylic acid or methacrylic acid with maleic acid. To improve water solubility, the polymers can also contain allyl sulfonic acids, such as allyloxybenzene sulfonic acid and methallyl sulfonic acid, as a monomer.
