Abstract

The invention relates to cosmetic cleansing products, in particular shower products, which contain a high ratio of oils, at least one acrylate polymer-based thickener and at least one cationic polymer.

Description

Shower products with higher oil contents

The present invention encompasses cosmetic cleansing products, in particular shower products containing a higher proportion of oils, thickeners based on acrylate polymers and cationic polymers.

Cleansing of the skin and skin appendages is part of everyday life in many cultures today, almost comparable to eating and drinking. During cleaning, dirt, which is often in the form of a film on the surface of the skin, is removed from the surface of the skin. The dirt film consists of solid or liquid components that have come from the outside on the skin. The dirt film also includes excess skin lipids and dead body cells. Surface-active ingredients in the cleaning compositions remove the components of the dirt film from the skin during the rinsing process and enter the wash liquor. In addition to the removal of the dirt film, however, depending on the cleaning conditions, more or less surface lipids of the skin, for example barrier lipids, can be dissolved by the surface-active substances in the cleaning preparations and removed in the rinsing process. Loss of skin lipids can cause dehydration and skin irritation.

These undesirable effects are particularly noticeable in people with dry skin. Dry skin is characterized by a lack of moisture and fatty substances in the uppermost skin layer. The skin is rough, flaky, lackluster and not very elastic.

But even normal skin is burdened by frequent washing because, as described above, the skin lipids and water-binding substances are removed with each washing. This phenomenon is counteracted by the use of mild cleaning products. The mild cleansing products, which typically contain mild surfactants, seek to minimize the washout of skin's own lipids and water-binding substances. Furthermore, there are cleaning products that contain oils to supply the skin with lipids again during the washing process and thus compensate for the loss of lipids. Oil-containing cleaning products are known per se, as the prior art shows.

The document DE 44 24 210 describes cosmetic or dermatological shower preparations having a surfactant content of not more than 55% by weight and an oil content of more than 45% by weight, the preparations being essentially anhydrous. Due to the high oil content, these preparations have a regenerating effect on the general skin condition. At the same time you have a good foam development and a high cleaning power.

The document EP 0867176 describes shower preparations which have a high, but in comparison to the prior art, for example DE 44 24 210, lower oil content. However, it is still a high refatting achieved with better foam performance and compatibility. The water content is at most 3.5 wt .-%.

The document WO 03/051319 also discloses oily cleaning products. In this case, however, cleaning products based on oily microemulsions. A process for the preparation of these oily microemulsions is described. At a constant total amount of surfactant, the primary surfactant / cosurfactant ratio can be varied.

Document WO 2005/065629 discloses that oil-containing, anhydrous surfactant preparations can be designed in such a way that they counteract enzyme damage to the enzymes of the upper skin layers.

However, the preparations according to the StdT have disadvantages. First, the stability of the preparations is not satisfactory. Phenomena such as phase separation are observed.

Second, consistency is often inappropriate. The preparations may become thinner during storage, i. the viscosity decreases.

Third, formulations containing heavy oil usually have the disadvantage that they foam poorly. However, since a sufficient amount of creamy foam is often associated with good care by consumers, it is highly desirable to achieve good foaming even in cleaning formulations with higher oil contents. The object of the present invention was to provide cosmetic cleansing preparations, in particular shower preparations, with higher oil and surfactant contents, which have a consistency that the user perceives as pleasant. This means that the product can be easily and simply removed from the packaging and, on the other hand, is not so fluid that it immediately drains from the skin after removal from the package and after dispensing.

Since the products according to the invention sometimes have to cover long transport distances at different temperatures until they arrive at the point of sale or at the consumer, it is important that the original consistency is approximately maintained or sets in again.

Furthermore, it may be desirable to incorporate solid particles in the preparations according to the invention. These particles should be stably suspended and remain so even with prolonged storage.

For users, it is important, especially for cleaning products with higher oil contents, that adequate care is achieved.

Surprisingly, all these tasks were solved by

cosmetic cleansing preparations, in particular shower preparations containing a. 10-35% by weight of at least one lipid, wherein at least one lipid is liquid, b. at least one anionic surfactant, preferably selected from alkyl ether sulfates, amino acid surfactants and mixtures thereof,

The preparations according to the invention have a flowable to cream-like consistency and are advantageously in the form of emulsions.

The preparations according to the invention are aqueous preparations, ie these preparations contain at least 50% by weight of water, preferably at least 55% by weight of water. In the preparations according to the invention at least one lipid is contained, wherein at least one lipid is present in liquid form. In a further advantageous embodiment, two or more liquid lipids are contained. In an equally advantageous embodiment, in addition to one or more liquid lipids, one or more lipids are contained in solid and / or semisolid form.

Liquid lipid means that this lipid is liquid at 20 ° C. A solid lipid is present at 20 ° C in solid form. Semi-solid lipids are neither liquid nor solid at 20 ° C, but have a pasty consistency.

The liquid lipids are native and / or mineral and / or synthetic oils. Preferably, the liquid lipids are of natural origin, more preferably vegetable oils. It is particularly preferred in particular if the liquid lipids are selected from the group of castor oil, soybean oil, sunflower oil, rapeseed oil, coconut oil and mixtures thereof. Also particularly preferred is an oil which is provided with the INCI name Olus Oil. It is for instance available under the tradename Lipex ^® Bassol C by the company AAK.

The at least one lipid, wherein at least one lipid is liquid, is present at a level of from 10 to 35% by weight, preferably from 15 to 30% by weight, based on the total weight of the preparation. The quantity refers to the total amount of lipids in the respective preparation. It follows that the amount given in the presence of only one lipid in the preparation refers to this lipid. However, if there are two or more lipids in the preparation, including an optionally selected, preferred lipid, the amount specified always refers to all lipids in the preparation.

The cleaning preparations contain at least one anionic surfactant. The at least one anionic surfactant is present at a level of from 1 to 10% by weight, based on its active content and the total weight of the inventive composition.

6. Alaninates.

Particularly advantageous amino acid surfactants are preferably selected from the group of acylglyci- nate. The cations of acylglycinates are selected from the group of sodium ions and potassium ions, preferred are sodium ions.

In embodiments in which at least one amino acid surfactant is present, the amino acid surfactant sodium cocoyl glycinate, which is obtainable, for example, under the trade name Hostapon SG from Clariant, is particularly preferably selected.

In the embodiments comprising at least one amino acid surfactant, the at least one amino acid surfactant is advantageously present in concentrations of up to 5% by weight, preferably 1 to 4% by weight, based on the active content and the total weight of the preparation. The amount refers to the total amount of one amino acid surfactant or more amino acid surfactants in each preparation. If two or more amino acid surfactants are present in the preparation, including an optionally selected, preferred amino acid surfactant, then the amount specified always refers to all amino acid surfactants in the preparation.

Advantageous anionic surfactants according to the invention can be selected from the sulfuric acid esters; These include compounds such as

1 . Alkyl ether with different degrees of ethoxylation and mixtures thereof, for example, sodium, ammonium, magnesium, MI PA, TIPA-Laureth-X-sulfate, sodium myreth-X-sulfate and sodium C12-13-Pareth-X-sulfate, with X = 1-5 ethoxy groups.

2. Alkyl sulfates, for example sodium, ammonium and TEA lauryl sulfate, sodium ammonium and TEA cocosulfate.

Particularly advantageous are embodiments which contain alkyl ether sulfates. According to the invention, in particular, alkyl ether sulfates furthermore have alkyl radicals which are predominantly alkyl radicals having 8 to 18 carbon atoms, in particular even more advantageously predominantly alkyl radicals having 10 to 16 carbon atoms. Alkyl ether sulfates are in the form of salts, the preferred cations are sodium, potassium and NH ₄ ⁺ .

Very particular preference is given to the alkyl ether sulfate sodium lauryl ether sulfate, which is available, for example, from Oleochemicals under the trade name Texapon® N70.

The at least one alkyl ether sulfate is in the compositions according to the invention with a content of 4.0 to 10.0 wt.%, Preferably 5.0 to 7.5 wt .-%, based on the Active content and the total weight of the preparation, before. This concentration always refers to the total concentration of alkyl ether sulfates.

Embodiments which contain anionic surfactants in the form of alkyl ether sulfates, amino acid surfactants and / or mixtures thereof are therefore preferred according to the invention.

According to the invention, the incorporation of one or more amphoteric surfactants into the preparations according to the invention is advantageous. The inventively advantageous amphoteric surfactants preferably contain a betaine structural element. Co-camidopropylbetaine is particularly preferred. Such a compound can be obtained, for example, from Evonik Industries under the trade name Tego Betain F50.

The at least one amphoteric surfactant is present in the formulations according to the invention with a content of 1.0 to 5.0% by weight, preferably 2.0 to 4.0% by weight, based on the active content and the total weight of the preparation. This concentration always refers to the total concentration of amphoteric surfactants.

Anionic surfactants are present in the raw materials used completely or for the most part dissociated. The corresponding cations are therefore present in the same concentration as the surfactant anions. In the case of amphoteric surfactants, synthesis-related salts often accumulate as a secondary constituent. For example, the raw material TEGO Betain F 50 contains 5.8 to 7.3% NaCl.

It follows that a significant amount of salt enters the preparations according to the invention with the raw materials used of the anionic and amphoteric surfactants. This presents the expert in the production of the preparations according to the invention with the challenge that, despite the comparatively high salt contents, such preparations should be stable and must also form an acceptable foam in terms of quantity and quality.

With the above-described cosmetic cleansing preparations containing 10-35% by weight of lipids, wherein at least one lipid is liquid, anionic surfactants, acrylate-based thickening polymers and cationic polymers, preparations can be prepared which, despite the high salt content, are stable and develop a sufficient creamy foam , Acrylate-Based Thickening Polymers Polymers are polymers which contribute to the compositions according to the invention having a user-compatible consistency. The acrylate-based thickening polymers are composed of unitarily structured structural units of synthetic nature, wherein at least one of the structural units derived from acrylic acid / methacrylic acid or its salts. It is preferred if there is another type of structural unit which is also derived from acrylic or methacrylic acid and has a hydrophobic residue of 10 to 30 carbon atoms. It is particularly preferred if the acrylate-based thickening polymers contain only the two aforementioned types of structural units. An example of such particularly preferred polymers is the polymer with the INCI name Acrylates / C10-30 alkyl acrylate crosspolymer.

This INCI name distributes various commercial products. For example, Lubrizol offers the commercial products Pemulen® TR-1, Carbopol® 1382 Polymer, Carbopol® Ultrez 20 Polymer, Carbopol® Ultrez 21 Polymer and Carbopol® ETD 2020 Polymer with this INCI name. All these commercial products are particularly preferred according to the invention to use.

The at least one acrylate-based thickening polymer is present in the preparations according to the invention with a content of 0.1 to 1.5% by weight, preferably 0.2 to 1.0% by weight, based on its active content and the total weight of the preparation. This concentration refers to the total content of acrylate-based thickening polymers in the preparation according to the invention.

For individual commercial products, it is advantageous to further optimize the use concentrations. It is preferred, for example, that Carbopol® Ultrez 21 polymer and

Pemulen® TR-1, each used individually, in the concentration range 0.4 to 1, 0 wt .-%, based on their active content and the total weight of the preparation, are present. It is likewise preferred, for example, to use a combination of Carbopol® Ultrez 20 polymer or Carbopol® Ultrez 21 polymer with Pemulen® TR-1, the polymers Carbopol® Ultrez 20 polymer or Carbopol® Ultrez 21 polymer in each case in a concentration of 0, 7 to 1.0 wt .-% and the polymer Pemulen® TR-1 in a concentration of 0.1 to 0.3 wt .-%, based on their active content and the total weight of the preparation present.

Cationic polymers are polymeric compounds having cationic groups in the main or side chain. These groups can be temporarily cationic. It acts These are, for example, primary, secondary or tertiary amine groups present as positively charged groups at appropriate pH values.

Permanent cationic groups are always positively charged, regardless of the pH. It is usually a quaternary nitrogen atom, for example in the form of an ammonium group.

The at least one cationic polymer is present in the preparations according to the invention with a content of 0.05 to 1.0% by weight, preferably 0.1 to 0.5% by weight, based on its active content and the total weight of the preparation. This concentration refers to the total concentration of cationic polymers.

Cationic polymers may be natural polymers that have been modified such that, for example, permanent cationic groups, especially quaternary ammonium groups, have been introduced into the molecule. Quaternary ammonium groups are preferred cationic groups according to the invention. These groups can be introduced, for example, into cellulose molecules or guar molecules.

Particularly preferred according to the invention is polyquaternium-10, which is available, for example, under the trade name Ucare Polymer JR 400 from Dow Chemical. Also particularly preferred according to the invention are cationic guar derivatives in the preparations according to the invention, in particular guar hydroxypropyltrimonium chlorides.

Cationic polymers may also be synthetic polymers containing monomers with cationic groups. Preference is given in this case if the monomer having the cationic group has a permanently cationic group, particular preference is given to dimethyl dialyl ammonium chloride as the monomer. A particularly preferred cationic synthetic polymer is Polyquaternium-7, which is available, for example, as Mirapol 550 P from Solvay.

Another particularly preferred synthetic cationic polymer containing the monomer dimethyl diallyl ammonium chloride is Polyquaternium-39. This polymer is available, for example, as Merquat 3300PR from Lubrizol. It is equally advantageous to combine the particularly preferred cationic polymers, namely polyquaternium-10, guar hydroxypropyltrimonium chlorides, polyquaternium-7 and polyquaternium-39, in the form of two-membered or triple combinations.

Fatty alcohols are 1-alkanols and are often derived from fatty acids. Fatty acids of natural origin usually have an even number of carbon atoms, therefore, the fatty alcohols of natural origin usually have an even number of carbon atoms.

The term fatty alcohol in the narrower sense is used for alcohols with a chain length of six (hexanol) up to 22 carbon atoms (behenyl alcohol). Higher primary alcohols having 24 to 36 carbon atoms are called wax alcohols. In cosmetics, fatty alcohols are often used as nonionic surfactants, as a basis for creams and ointments and as emulsifiers.

As fatty alcohols according to the invention it is possible to use saturated, mono- or polyunsaturated, branched or unbranched fatty alcohols having C 6 -C 22 -, preferably C 10 -C 20, and particularly preferably C 12 -C 18 -carbon atoms. Suitable for the purposes of the invention are, for example, decanol, octanol, octenol, dodecanol, dodecenol, decenol, octadienol, dodecadienol, decadienol, oleyl alcohol, erucalcohol, ricinol alcohol, stearyl alcohol, isostearyl alcohol, cetyl alcohol, lauryl alcohol, myristyl alcohol, arachidyl alcohol, capryl alcohol, capric alcohol , Linoleyl alcohol, linolenyl alcohol and behenyl alcohol.

However, the fatty alcohols according to the invention are preferably derived from natural fatty acids. Since fatty acids can be unsaturated, this also applies to the alcohols that are obtained from them. Also suitable according to the invention are those fatty alcohol mixtures obtained by hydrolysis and reduction of naturally occurring triglycerides such as beef tallow, palm oil, peanut oil, cottonseed oil, soybean oil, sunflower oil, coconut oil and linseed oil. For sale are usually mixtures of different fatty alcohols.

Very particular preference according to the invention is given to preparations which contain myristol alcohol, cetyl alcohol and / or stearyl alcohol. The alcohols mentioned can be used individually, in combinations of two or in a threefold combination. The at least one fatty alcohol is present in the preparations according to the invention at a content of 0.1 to 3.0% by weight, preferably 0.5 to 2.5% by weight, based on the total weight of the preparation. This information refers to the total content of fatty alcohols.

The preservation of the preparations according to the invention can be carried out in the manner customary for cosmetic preparations. The concentration of preservatives is according to the invention 0.05 to 3.3 wt .-%, preferably 0.1 to 2.6 wt .-%, based on the total weight of the preparation according to the invention.

According to the invention, the following are advantageous as preservatives:

Benzoic acid, salicylic acid, sorbic acid and / or salts thereof,

Parabens,

Phenoxyethanol.

A preservative with benzoic acid and / or a salt of benzoic acid, with salicylic acid and / or a salt of salicylic acid and / or with sorbic acid and / or a salt of sorbic acid is advantageous. The preservation with sodium benzoate and / or sodium salicylate is particularly advantageous. Benzoic acid, salicylic acid, sorbic acid and / or salts thereof are present at levels of from 0.05 to 1.5% by weight, preferably from 0.1 to 1.0% by weight, based on the total weight of the preparation. The concentration refers to the total amount of said beneficial preservatives.

Also advantageous is a preservation with parabens. The general structural formula of the parabens is shown below:

R is alkyl side chain, which may consist of a straight or branched chain of 1 to 5 carbon atoms or aromatic radicals. Known parabens are methyl, ethyl, propyl-butyl paraben, as well as isopropyl, isobutyl, pentyl and phenyl paraben. Benzylparaben is not approved as a preservative in cosmetic products. Particularly advantageous methyl and Ethylparaben be used, individually or in combination.

The paraben or parabens is / are present in the preparations according to the invention with a content of 0.2 to 0.8% by weight, preferably 0.5 to 0.7% by weight, based on the total weight of the preparation. This concentration refers to the total concentration of parabens.

Also advantageous is a preservative with phenoxyethanol. Phenoxyethanol is used at a level of from 0.3% by weight to 1.0% by weight, preferably from 0.6% by weight to 0.9% by weight, based on the total weight of the preparation.

Furthermore, it is advantageous according to the invention to use benzoic acid, salicylic acid, sorbic acid and / or salts thereof together with at least one paraben and / or phenoxyethanol in each of the amounts mentioned for preservation.

Antioxidants inhibit or prevent changes in or on substances to be protected, which are triggered by oxygen or other oxidative processes. Antioxidants are compounds that have different chemical structures. There are natural antioxidants, such as tocopherols (vitamin E), tocotrienols and flavonoids, and synthetic antioxidants. Compounds such as butylhydroxyanisole (BHA), butylhydroxytoluene (BHT), ascorbyl palmitate and gallic acid esters can be expected as synthetic antioxidants. Vitamin E and / or its derivatives and / or butylhydroxytoluene are preferably used in the preparations according to the invention.

Vitamin E and / or its derivatives are present in a total concentration of 0.001 to 1.0% by weight, preferably 0.005 to 0.1% by weight, based on the total weight of the preparation.

Butylhydroxytoluene is present at a level of from 0.01 to 0.1% by weight, preferably 0.02 to 0.05% by weight, based on the total weight of the preparations, in the preparations according to the invention.

The preparations of the invention are characterized by a more or less cream-like consistency and are nevertheless easy to remove from the packaging unit, ie they are flowable. To achieve the said cream-like consistency, are to comply with certain viscosity values. The viscosity values are advantageously between 1, 500 and 15,000 mPas, in particular between 2,000 and 10,000 mPas. The viscosity values are measured with a proRheo Rheomat R 123 at 25 ° C, as required with spindle 1 or 2.

The preparations according to the invention are further distinguished by the formation of a yield point. The yield stress is the critical shear stress of the flow curve. It can be determined according to the invention as follows:

The flow curve is measured on a shear stress controlled rheometer at 25 C ± 1 ° C with 25 mm plate / plate geometry at a gap between 0.8 mm and 1, 2 mm, filling the structure gently. A suitable constant shear stress ramp is specified and a corresponding structure recovery time is maintained before the test and the critical shear stress is specified at the maximum of the flow curve.

Advantageously, the preparations are designed so that they have a yield value of 1-18 Pa, preferably 3-16 Pa.

Under tan delta according to the invention the quotient of the loss modulus and the memory module understood. The tan delta is determined as follows:

The loss and storage modulus are measured by a dynamic frequency test on a shear stress controlled rheometer at 40 C ± 1 C with 25 mm plate / plate geometry at a gap between 0.8 mm and 1, 2 mm, filling in a gentle way. It is performed according to the prior art, the frequency test with a corresponding Strukturerholungszeit before the test and the tan d in the frequency range between 0.05 rad / s and 4.0 rad / s specified, preferably between 0.08 rad / s and 1.0 rad / s.

Advantageously, the preparations are designed so that they have a tan d of 0.05 to 0.8, preferably 0.3 to 0.6.

Since the preparations of the invention form a yield point and have a tan delta value less than 0.8, the incorporation of, for example, solid particles is ensured, wherein said components are largely stable suspended and remain largely stable distributed. The solid particles may be of natural or synthetic origin. Preference is given to the use of particles of natural origin, which may be selected from alumina, sand, crushed or crushed cores of walnut shells, apricot, peach and / or almond kernels, peeling bodies of waxy, solid bases such as hardened castor oil, jojoba oil, carnauba wax , Candelella wax, Tempered sunflower oil, ice germ oil, hardened soybean oil and paraffin. Also preferred are peeling bodies of silica and silicates or polylactides. Also possible, although not desired, is the use of synthetic peeling agents. Furthermore, the particles may be filled with active ingredients beads or microcapsules. Mixtures of said particles, as well as mixtures of said particles with drug-filled beads and microcapsules are also preferred.

The solid particles have a content of 0.05. to 2.0 wt .-%, preferably from 0.5 to 1, 5 wt .-%, based on the total weight of the preparation, before.

In order to investigate the storage stability of a preparation, there are various possibilities. First, measuring viscosity over time, often over three months, is a good indicator of storage stability.

In order to shorten this observation period, preparations to be examined can be stored in a changing temperature cabinet for 7 or 14 days. In this cabinet, the temperature changes at certain time intervals; for 12 h is heated to 40 C or held the heat to 40 C, then 12h cooled to -10 C, and the temperature of - 10 ° C held, then again warming to 40 ° C or maintaining the Temperature of 40 ° C and so on.

Furthermore, the preparations can be stored at elevated temperature, up to 50 ° C. If, when stored for one month at elevated temperature, the viscosity does not deviate too much from the originally measured viscosity, this is an indication that the preparation is stable over a prolonged period, for example one year.

In addition, there are other ways to predict the stability of a preparation. These include, for example, centrifugation at certain g-values or analysis of droplet size distribution in an emulsion.

Preparations according to the invention show better long-term stability compared to preparations without cationic polymers. For a selected preparation containing 0.15% by weight of Polyquaternium-10 and 0.1% by weight of Polyquaternium-39 (see Investigation I, Example 2), viscosity values of 4,750 mPa · s at 25 ° C., 750 mPa · s be measured at 40 ° C and 3,100 mPa-s after tempering from 40 ° C to 25 ° C. For a comparable sample without cationic polymers (see Study I, Example 1), viscosity values of 4,450 mPa · s at 25 ° C., 800 mPa · s at 40 ° C. and 1,700 mPa · s after tempering measured from 40 ° C to 25 ° C. The cationic polymers thus contribute to the compositions becoming more viscous again after the heat treatment, ie the viscosity values are markedly higher than in the case of the preparation without cationic surfactants. A similar picture appears when stored at -10 ° C or in the change temperature cabinet; the preparation with the cationic polymers shows a better flow behavior after tempering to room temperature than the preparation without cationic polymers.

In a second series of experiments (see Investigations I, Examples 3 to 5), two further cationic polymers were investigated and the storage times at 40 ° C. were extended. It shows a similar picture, as in the first series of experiments. In the case of the preparations with cationic polymers, a higher viscosity was measured after the heat treatment and tempering at 25 ° C. than in the case of the preparation without cationic polymers. Also, the flow behavior after storage at -10 ° C or in the changing temperature cabinet was better evaluated in the preparations with the respective cationic polymers, as in the preparation without cationic polymers.

In addition, further investigations were carried out with preparations containing cationic polymers and fatty alcohols in comparison to preparations which do not contain the components mentioned.

In a first series (see Investigations II, Examples 1 to 3) preparations were studied which contained the cationic polymers Polyquaternium-10 and Polyquaternium-39 and cetyl alcohol or stearyl alcohol. It turned out that the alcohols have different effects. In the case of preparations with stearyl alcohol, the measured viscosity values after the heat treatment (60 days at 40 ° C.) and temperature control to 25 ° C. were the best, ie at least far from the viscosity value, which remains constant at 25 ° C. (= K 25 value). measured is removed. The corresponding viscosity values for samples with cetyl alcohol are further from the K25 value than for the sample without alcohol. However, if the viscosity values after storage at 6 ° C and tempering at 25 ° C, it is found that cetyl contributes to the fact that on the one hand, the viscosity value at 6 ° C is significantly lower than in the preparation without fatty alcohol and the preparation with stearyl alcohol. On the other hand, the viscosity value after tempering to 25 ° C deviates least from the K25 value. The assessments of the flow behavior show a suitable picture. The preparations containing the fatty alcohols mentioned are better evaluated after storage at -10 ° C. or in the alternating temperature cabinet than the preparation without alcohol. Overall, the preparation is rated best with stearyl alcohol.

It follows that the addition of the fatty alcohols mentioned has an effect on the storage stability, as can be deduced from the data of the viscosity measurements and the assessment of the flow behavior.

In a second series (see Investigations II, Examples 4 and 5) preparations were investigated which contained 0.5% by weight of cetyl alcohol and no cationic polymers, or no cationic polymers and no fatty alcohols. It is also evident in this series that the effect of cetyl alcohol is again visible when stored at 6 ° C. The viscosity values during storage at 6 ° C. differ significantly less from the K25 value than in the case of preparation without fatty alcohols. The assessment of the flowability shows, however, that both preparations with fatty alcohol and without cationic surfactants and preparations without fatty alcohol and without cationic surfactants are considered to be low viscosity and thus have no appealing consistency.

The preparations according to the invention develop a foam which is classified as creamy and forms in a sufficient amount. The users attest to the products according to the invention a good care performance.
