[0002] Synergistic association of biobased materials with cationic polymers for enhanced performance

[0003] The present invention is directed to a combination of a biosurfactant and a bio-based cationic polymer selected from cationic polymers derived from polysaccharides, a laundry detergent, cleaning or hair care composition comprising said combination and the use of said combination to enhance the cleaning performance of a laundry detergent, cleaning or hair care composition.

[0004] Sustainably sourced, environmentally friendly ingredients are becoming increasingly relevant for both producers and consumers. However, conventional, fossil-based surfactants have hitherto been preferred regarding their soil removal abilities.

[0005] It was therefore an object of the invention to provide an eco-friendly composition with satisfactory cleaning properties.

[0006] Surprisingly it was found that a combination of a biosurfactant and a bio-based cationic polymer selected from cationic polymers derived from polysaccharide showed an improvement regarding soil removal compared to its components.

[0007] Thus, in a first embodiment the subject-matter of this invention is a combination of a biosurfactant and a bio-based cationic polymer selected from cationic polymers derived from polysaccharides.

[0008] In a second embodiment the invention relates to a laundry detergent, cleaning or hair care composition comprising said combination.

[0009] The combination was shown to enhance the cleaning performance of a laundry detergent, cleaning or hair care composition. The invention is therefore concerned with the use of the combination to enhance the cleaning performance of a laundry detergent, cleaning or hair care composition in a further embodiment.

[0010] These and other aspects, embodiments, features, and advantages of the invention become apparent to the person skilled in the art in the following detailed description and claims. Each feature from one aspect of the invention can be used in any other aspect of the invention. Furthermore, the examples contained herein are intended to describe and illustrate the invention, but do not restrict it. In particular, the invention is not limited to these examples.

[0011] “At least one”, as used herein, means one or more, i.e. 1 , 2, 3, 4, 5, 6, 7, 8, 9 or more of the referenced species. Similarly, “one or more”, as used herein, relates to at least one and comprises 1 , 2, 3, 4, 5, 6, 7, 8, 9 or more. In connection with a given species, the term does not relate to the total number of molecules, but rather to the type of species. “At least one betaine”, for example, thus means that one type of betaine or two or more different types of betaines may be present. In connection with amounts, the term relates to the total amount of the referenced species. With betaines, for example, this means that the given amount is the total amount of all betaines in the composition.

[0012] Numeric values specified without decimal places here refer to the full value specified with one decimal place, i.e. for example, 99 % means 99.0 %, unless otherwise defined.

[0013] The terms “about”, “approximately” or “approx.”, in connection with a numerical value, refer to a variance of ±10 %, preferably ±5 %, with respect to the given numerical value.

[0014] The term “essentially free” within the context of this invention is to be interpreted as the respective compound is contained in the composition in an amount of less than 5 wt.-%, 4 wt.-%, 3 wt.-%, 2 wt.-%, 1.5 wt.-%, 1 wt.-%, 0.75 wt.-%, 0.5 wt.-%, 0.25 wt.-%, 0.1 wt.-%, 0.01 wt.-%, or 0.001 wt.-% based on the total weight of the composition, wherein the amounts are respectively more preferred in descending order. For example, 4 wt.-% is more preferred than 5 wt.-% and 3 wt.-% is more preferred than 4 wt.-%.

[0015] All percentages given herein in relation to the compositions or formulations relate to weight % (wt.- %) relative to the total weight of the respective composition or formula, if not explicitly stated otherwise. Numeric ranges specified in the format "from x to y" include the specified values. If multiple preferred numeric ranges are specified in this format, it is understood that all ranges created by combining the different endpoints are also included.

[0016] “Laundry detergents” according to the present invention comprise all conceivable textile washing and / or care compositions used in the washing machine or in hand washing. This includes, for example, detergent compositions and compositions for cleaning, care and / or conditioning, pre- and / or post-treatment of all types of textiles, such as garments, carpets, and textile furniture surfaces.

[0017] “Cleaning compositions” according to the present invention comprise all conceivable compositions used in the household for cleaning and care of hard surfaces, including bathroom and kitchen surfaces and appliances, mirrors, windows and other glass surfaces, floors and furniture, as well as automatic and hand dishwashing compositions.

[0018] “Hair care compositions” according to the present invention comprise all conceivable compositions used for cleaning and / or conditioning hair, i.e. shampoos, conditioners, lotions and the like.

[0019] The laundry detergents, cleaning compositions and hair care compositions according to the present invention may be in any form known for such products. Thus, it may be a liquid, gel-like or paste- like composition or a solid composition in the form of a powder, granules, a bar, a block, a tablet and the like. It may also be in the form of a unit-dose composition in a pouch, sachet or the like. The term “liquid”, as used herein, refers to compositions that are flowable and pourable at standard conditions (20 °C and 1013 mbar). Non-Newtonian liquids are comprised as well.

[0020] In a first embodiment the subject-matter of this application is a combination of a biosurfactant and a bio-based cationic polymer.

[0021] Biosurfactants usually are surfactants of microbial origin. They are composed of a hydrophilic moiety, which typically is made up of amino acids, peptides, mono-, di- or polysaccharides or sugar alcohols, and a hydrophobic moiety consisting of fatty acids. Preferred biosurfactants include glycolipids, lipopeptide / lipoproteins and polymeric surfactants.

[0022] In a preferred embodiment the biosurfactant is selected from glycolipids, preferably from the group consisting of sophorolipids and rhamnolipids, and more preferably is a sophorolipid.

[0023] Sophorolipids are glycolipids consisting of a hydrophobic fatty acid “tail” and a hydrophilic carbohydrate “head” which is sophorose, a disaccharide in which two glucose molecules are connected with a p-1 ,2 glycosidic bond. The fatty acid is typically a Ci 6-22 saturated or unsaturated hydroxy fatty acid; its terminal or internal OH group is p-glycosidically linked to the sophorose molecule. The carboxylic end of the fatty acid may be free, as in the following examples:

[0024]

[0025] Alternatively, they may be internally esterified to form monomeric or dimeric lactones, as in the following examples.

[0026] The open (acidic) form and the lactonic form may also be present simultaneously. In general, lactone sophorolipids are more efficient in reducing surface tension whereas acidic sophorolipids display better foaming properties. The hydroxy groups of the sophorose moiety may also be completely or partially esterified with carboxylic acids such as acetic acid. Sophorolipids are produced by various yeast species such as Candida albicans, Candida apicola, Candida floricola, Candida kuoi, Candida riodocensis, Candida stellata, Candida tropicalis, Candida parapsilosis, Rhodotorula bajevae, Rhodotorula bogoriensis, Wickerhamiella domercqiae, Wickerhamomyces anomalus and Starmerella bombicola, and can be obtained from these microorganisms through fermentation.

[0027] Rhamnolipids are glycolipids in which a mono- or di-rhamnose unit is glycosid ically linked to the hydroxy group of a p-hydroxy fatty acid, which may in turn be esterified with the hydroxy group of another hydroxylated fatty acid. They can be obtained by fermentation of Pseudomonas bacteria, especially Pseudomonas aeruginosa, preferably grown on hydrophobic substrates such as n- alkanes or vegetable oils.

[0028] Some examples of rhamnolipids are: There are two main classes of rhamnolipids, namely mono-rhamnolipids, which contain one rhamnose unit, and di-rhamnolipids with two rhamnose groups. Besides C10- carboxylic or hydroxycarboxylic acids, typical rhamnolipids may also contain carboxylic or hydroxycarboxylic acids with longer alkyl chains, such as C12. It is preferred for at least 50 wt.-% of the rhamnolipids to be di-rhamnolipids, preferably at least 90 wt.-% and up to 100%.

[0029] A second necessary component is a bio-based cationic polymer, in particular a cationic polymer derived from polysaccharides. Preferred cationic polymers are based on polysaccharides selected from the group consisting of guar gum, starch, dextrin, cellulose, chitin, chitosan, agarose and mixtures thereof. The cationic modification is preferably effected through the introduction of amino or ammonium functional groups, for example substitution with dialkylamino hydroxypropyl ethers or trialkylammonium hydroxypropyl ethers. In a preferred embodiment the bio-based cationic polymer is a guar-based polymer, preferably guar hydroxypropyl trimonium chloride (GHTC).

[0030] In a preferred embodiment the combination according to the invention may also comprise one or more acidic and / or alkaline ingredients to adjust the pH value. Preferred acids may be selected from the group comprising C1-8 carboxylic or hydroxycarboxylic acids such as acetic acid, lactic acid, citric acid, tartaric acid, malic acid, succinic acid or salicylic acid, amino acids such as glycine, glutamic acid, aspartic acid or arginine, as well as mineral acids such as hydrochloric acid or sulfuric acid. Among these, citric acid, lactic acid and acetic acid are particularly preferred, as are a-hydroxycarboxylic acids in general. Preferred alkalis may be selected from alkali metal or alkaline earth metal hydroxides such as sodium hydroxide or potassium hydroxide, ammonium hydroxide, as well as amines or alkanolamines such as monoethanol amine, diethanol amine or triethanol amine.

[0031] The combination preferably has a pH value, measured neat at room temperature, of 3.0 to 8.0, more preferred 4.0 to 6.0, especially preferred 5.0.

[0032] A further aspect of the invention is a laundry detergent, a cleaning composition or a hair care composition comprising a combination of a biosurfactant and a bio-based cationic polymer.

[0035] The additional surfactant may be selected from anionic, non-ionic, zwitterionic, amphoteric and / or cationic surfactants.

[0036] Among the anionic surfactants that can additionally be used are those of the sulfonate and sulfate types. Surfactants of the sulfonate type that can be used are preferably C9-13 alkylbenzene sulfonates, olefin sulfonates, i.e. mixtures of alkene and hydroxyalkane sulfonates, and disulfonates, as obtained, for example, from C12-18 monoolefins having a terminal or internal double bond by way of sulfonation with gaseous sulfur trioxide and subsequent alkaline or acid hydrolysis of the sulfonation products. Alkane sulfonates obtained from C12-18 alkanes, for example by way of sulfochlorination or sulfoxidation with subsequent hydrolysis or neutralization, are also suitable. Likewise, the esters of a-sulfofatty acids (ester sulfonates) are suitable, for example the a- sulfonated methyl esters of hydrogenated coconut fatty acids, palm kernel fatty acids or tallow fatty acids.

[0037] The alkali salts and in particular the sodium salts of the sulfuric acid half-esters of C12-C18 fatty alcohols, for example from coconut fatty alcohol, tallow fatty alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol or stearyl alcohol, or of C10-C20 oxo alcohols and the half-esters of secondary alcohols having these chain lengths are preferred as alk(en)yl sulfates. Alk(en)yl sulfates of the mentioned chain length with synthetic straight-chain alkyl groups prepared from petrochemical sources may also be used. However, it is preferred that the alkyl chain is derived from renewable, natural sources.

[0038] Alkyl ether sulfates are ethoxylated sulfuric acid monoesters of straight-chain or branched alcohols, preferably of C10-C18 fatty alcohols, for example from coconut fatty alcohol, tallow fatty alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol or stearyl alcohol, or of C10-C20 oxo alcohols. They are preferably ethoxylated with 1 to 10 mol of ethylene oxide (EO), especially preferably 1 to 4 EO. A particularly preferred alkyl ether sulfate is sodium laureth sulfate.

[0039] Further suitable anionic surfactants include sulfated fatty acid glycerol esters as well as the salts of alkyl sulfosuccinic acid, which are also referred to as sulfosuccinates or as sulfosuccinic acid esters.

Soaps, especially saturated fatty acid soaps are also suitable, such as the salts of lauric acid, myristic acid, palmitic acid, stearic acid, hydrogenated erucic acid and behenic acid, and in particular soap mixtures derived from natural fatty acids, such as coconut fatty acids, palm kernel fatty acids or tallow fatty acids.

[0040] The anionic surfactants, including the soaps, can be present in the form of the sodium, potassium, magnesium or ammonium salts thereof, or as soluble salts of organic bases, such as monoethanolamine, choline or triethylamine.

However, alcohol ethoxylates having linear groups of alcohols of native origin having 12 to 18 C atoms, for example of coconut, palm, tallow fatty or oleyl alcohol, and an average of 2 to 8 EO per mol of alcohol, are particularly preferred. Examples of preferred ethoxylated alcohols include C12-14 alcohols having 3 EO or 4 EO, C9-11 alcohol having 7 EO, C13-15 alcohols having 3 EO, 5 EO, 7 EO or 8 EO, C12-18 alcohols having 3 EO, 5 EO or 7 EO, and mixtures thereof, such as mixtures of C12-14 alcohol having 3 EO and C12-18 alcohol having 5 EO. The degrees of ethoxylation indicated represent statistical averages that can correspond to an integer or a fractional number for a specific product. Preferred alcohol ethoxylates have a narrowed homolog distribution (narrow range ethoxylates, NRE). In addition to these non-ionic surfactants, fatty alcohols having more than 12 EO can also be used. Examples of these are tallow fatty alcohols having 14 EO, 25 EO, 30 EO, or 40 EO.

[0042] Amine oxides are another class of non-ionic surfactants which may be used. They are described by the formula R1R2R3NO, in which each R1, R2and R3independently is an unsubstituted or substituted (i.e. hydroxysubstituted) C1-C30 hydrocarbon chain. In preferred amine oxides, R1stands for C12-C18 Alkyl and R2und R3independently of one another are C1-C4 alkyl, especially C12-C18 alkyl dimethylamine oxide. Suitable amine oxides include N-cocoalkyl-N,N-dimethylamine oxide and N-tallowalkyl-N,N- dihydroxyethylamine oxide.

[0060] Examples

[0061] Cleaning performance

[0062] The cleaning performance of a combination of a sophorolipid and the cationic polymer Dehyquart Guar TC (Guar hydroxypropyl trimonium chloride, GHTC) was tested against soiled cotton fabric samples washed manually at 30°C and varying pH levels. The test was carried out with 5x5 cm swatches of cotton fabric substrate stained with a paste consisting of 13% soils (‘carbon black and coconut oil) and 87% light liquid paraffin (LLP) as a vehicle. The stains were dried for one hour and the swatches were then immersed in a solution of the composition diluted to contain 5% active detergent, stirring at 0, 20 and 40 minutes, before removing, drying and evaluating the stains.

[0063] The same tests were also carried out with the sophorolipid on its own as well as the GHTC on its own for the sake of comparison.

[0064] The following tests were carried out:

[0065] The sophorolipid used in these tests was an acid sophorolipid with 60% active matter (Sophorolipid LF, ex Dow)

[0066] Each assay was carried out three times. The samples were assessed visually after being washed and dried and were also compared with unsoiled and unwashed white and black fabric as control samples. The results can be ranked as follows:

[0067] A2 > A1 > C2 > C1 > C4 > C3

[0068] The inventive combination A2 showed the best soil removal, followed by the slightly more acidic inventive combination A1 . The soil removal exhibited by these combinations exceeded the effect expected due to the addition of the single components.
