Description

Cleansing Mousse

Technical field

The present invention relates to a foamable cleansing composition, especially a face cleans ing composition, in particular suitable as a make-up remover. The composition has effective cleansing properties and at the same time is a mild, non-irritating composition. The composi tion is made available in form of a mousse.

Background art

Generally, make-up is used to improve the outward appearance, in particular the appearance of the face. Already in ancient times make-up was used. In Egypt, at the times when the pharaohs were governing the country, the use of make-up for the eyes, lips and cheeks was common. Women and men used it to protect the skin against the sun, but also for beautifica tion. Nowadays, make-up is merely used to improve in particular the outward appearance of the face.

The applied make-up has to be removed. This may be achieved by face cleansers or prod ucts solely developed to remove make-up, so called make-up removers. The skin of the face is a relatively sensitive skin, therefore it is recommended to use mild cleansing compositions.

Make-up compositions contain a great number of raw materials, which are of very different chemical nature. The dyes, contained in make-up compositions, are selected from inorganic pigments such as silicates (magnesium silicate (talc), aluminum silicate (kaolin)), and metal oxides (chrome, iron, manganese, titanium, and zinc oxides), and/or organic pigments. Bind ing means may be esters of stearic acid, lanolin alcohol and lanolin acetate. Furthermore, waxes, such as for instance, beeswax or carnauba wax, and oils, such as for instance, paraf fin oil, silicone oil or castor oil, may be contained. Additionally, preservatives, antioxidants, thickeners and other additives may be comprised.

To achieve a proper face cleansing, these different compounds have to be removed from the skin. At the same time nonpolar substances such as waxes, oils and silicone oils and pig ments of low solubility, such as talc or titanium oxide, must be solubilized. This holds true for foundations, lipsticks, eye shadows, eye pencils, and also for long-lasting and waterproof products. Prior art discloses face cleansing compositions suitable to remove make-up as well. Different types of compositions are described and respective products are in the market. The compo sitions may be in form of emulsions, creamy, milky or liquid ones, gels and oily compositions, sometimes with two distinct phases, which are mixed upon shaking. Products mainly in form of foams have also been described.

Prior art discloses attempts to improve the foamability and the foam volume. For instance,

EP 3238697 A1 describes compositions containing one or more surfactants chosen from a specific set of surfactants, namely an anionic surfactant having a carboxyl group, an ampho teric surfactant and a nonionic surfactant and a specific derivative of an acyl basic amino acid, e.g., bis(Ne -lauroyl-L-lysine)sebacoyl amide or a salt thereof, and bis(Ns -octanoyl-L- lysine)sebacoyl amide, or a salt thereof.

EP 2740467 A1 discloses pumpable compositions, which are foam able. These compositions also contain a set of surfactants comprising amphoteric surfactants and nonionic surfactants.

Although WO 2007/1 1 1962 A2 is directed to provide solutions to the problem to provide foamable compositions containing relatively large particles, e.g. polyethylene particles, as aerosol products without a clogged or seeping valve, the examples disclose compositions containing an amphoteric surfactant, sodium lauroamphoacetate, and a block polymer, e.g., Poloxamer 182.

EP 1374848 A1 discloses a foaming cleanser composition containing clay, which could also be used as a mask. The surfactants comprised are Sodium Lauroyl Sarcosinate, which could be addressed as an acyl amino acid surfactant and Sodium Cocoamphacetate, an ampho teric surfactant.

WO 2017/148689 A1 discloses a shower preparation as an aerosol foam. The foam is de scribed as dense and creamy. The surfactants, which are preferably contained, are a specific set of anionic surfactants and alkyl poly glycosides. The use of certain acyl amino acid sur factants is also disclosed.

None of the aforementioned prior art is specifically directed to a cleansing mousse, espe cially a cleansing mousse for face cleansing. Mousses have a soft and creamy texture and are ideally to be applied to face skin, which is a sensitive one. Moreover, mousses can easily be applied to the skin and removed with water together with the solubilized dirt.

Hence, there has been the need to provide a product, which is a mild product, so to make it applicable to face skin, and at the same time it is a product effectively removing make-up.

Summary of the invention

In the meaning of the present applications the words“fill material” and“bulk” are synony mous to the composition of the invention containing at least one alkyl poly glycoside, at least one amphoteric surfactant, chosen from the group of alkyl amphoacetates, and at least one block polymer.

The composition according to the invention contains surfactants, namely at least one alkyl poly glucoside and at least one amphoteric surfactant, chosen from the group of amphoace tates. These surfactants are contributing to the generation of foam and the stability of the foam.

The nonionic surfactant(s) is/are chosen from alkyl poly glycosides, represented by the for mula RO-(Z)x, wherein R is the alkyl group having 6 to 30 carbon atoms, Z is a sugar moiety and x is the number of sugar moieties (1 .1 -5 on average). The alkyl poly glycosides accord ing to the invention may have a specific alkyl group, representing one distinct number of car bon atoms. In general, alkyl poly glycosides are produced starting from natural oils, prefera bly plant oils, more preferably coconut oil. In this case, the alkyl group R is a mixture of the alkyl groups of the respective fatty acids of natural oil used as a starting material.

It is preferred, if the alkyl poly glycosides have alkyl groups, where R essentially consists of C8 to C18 alkyl groups, preferably C8 to C12 alkyl groups.

The sugar moieties may be monosaccharides or oligosaccharides. In general, the sugar moi eties have 5 or 6 carbon atoms, which are contained as monosaccharides or oligosaccha rides. Examples for suitable sugar moieties are glucose, fructose, galactose, arabinose, ri- bose, xylose, lyxose, allose, altrose, mannose, gulose, idose, talose and sucrose. It is pre ferred, if the sugar moieties are glucose or sucrose. It is more preferred, if the sugar moiety is glucose.

The alkyl poly glycosides contain 1.1 to 5 sugar moieties on average, preferably 1 .1 to 2.0, more preferably 1.1 to 1 .8. It is most preferred, if the alkyl poly glycoside is decyl glucoside. Decyl glucoside may be purchased as a composition of 53% Decyl glucoside and 47% water, under the trade name Plantacare 2000 UP from BASF Personal Care and Nutrition.

Advantageously, the at least one alkyl poly glycoside is contained in an amount of 1 to 7.5 % by weight, preferably 1.5 to 5.0 % by weight, and more preferably 2.0 to 4.0 % by weight in the composition according to the invention, in relation to the active content and in relation to the total weight of the composition.

Alkyl amphoacetates may be described by the formula

wherein R is an alkyl residue of 8 to 19 carbon atoms.

In general, alkyl amphoacetates are synthesized in two steps. Firstly, a fatty acid, preferably having not less than 8 carbon atoms, or a blend of fatty acids derived from a natural oil, pref erably a plant oil such as coconut oil, soy bean oil or palm oil is reacted with A/-(2-Hydroxy- ethyl)ethylenediamine. The resulting 2-alkyl-1 -hydroxyethylimidazoline is hydrolysed with NaOH to a linear amidoamine and reacted with monochloroacetic acid to alkyl monoampho- acetate. If higher molar amounts of monochloroacetic acid are used, alkyl amphodiacetates are generated.

Alkyl amphoacetates are amphoteric surfactants, which behave as anionic, zwitterionic, or cationic surfactants depending on the pH value. Sodium salts of alkyl amphoacetate are known to contribute to the generation of rich foam and cause only less irritation of the skin and the eyes.

According to the present invention it is preferred, if the alky residue is derived from plant oil, more preferably coconut oil.

Furthermore, it is preferred, if sodium salts of alky amphoacetates are contained in the com position of the present invention.

It is most preferred, if sodium cocoamphoacetate is contained in the composition according to the invention. Sodium cocoamphoacetate may be purchased as a composition of 32.5% sodium cocoamphoacetate, 7.5% Sodium Chloride and 60% water, under the trade name Rewoteric AM C from Evonik Industries. Advantageously, the at least one alkyl amphoacetate is contained in an amount of 0.2 to 5.0 % by weight, preferably 0.5 to 3.0 % by weight, and more preferably 1 .0 to 2.5 % by weight in the composition according to the invention, in relation to the active content and in relation to the total weight of the composition.

The composition according to the invention contains at least one block polymer. Block poly mers are copolymers of ethylene oxide and propylene oxide units called poloxamer. They are characterized by the formula

H0(C₂H40)a(C₃H₆0)_b(C₂H40)aH where b has the values of 15 to 67 and a has the values of 1 to 130. The proportion of“a” units can be from 20 to 90% of the poloxamer. The poloxamers are characterized by their name; P stands for poloxamer, followed by three digits: the first two digits multiplied by 100 give the approximate molecular mass of the polyoxypropylene core, and the last digit multi plied by 10 gives the percentage polyoxyethylene content.

The following poloxamers may be used, Poloxamer 101 , Poloxamer 124 and Poloxamer 184. It is preferred, if poloxamer 184 is contained in the composition according to the invention. This compound is available, for example, under the trade name Pluracare L 64G from BASF.

Advantageously, the at least one block polymer is contained in a total amount of 0.1 to 8 % by weight, preferably 0.2 to 5 % by weight, more preferably 0.25 to 4 % by weight in the com position according to the invention, in relation to the total weight of the composition.

As described, above the composition according to the invention is an aqueous composition. Nevertheless it is advantageous, if hydrophobic components are contained. For instance, these hydrophobic components may be perfumes and/or certain preservatives. In order to solve these components in the composition according to the invention, emulsifiers or sub stances having emulsifying properties are contained. It is preferred, if emulsifiers are con tained, which have ethylene oxide units. It is more preferred, if one or more emulsifiers se lected from PEG-40 Hydrogenated Castor oil, PEG-200 Hydrogenated Glyceryl Palmate, and/or PEG-150 Distearate is contained. It is even more preferred, if PEG-40 Hydrogenated Castor oil, PEG-200 Hydrogenated Glyceryl Palmate, and PEG-150 Distearate are con tained. It is most preferred, if only PEG-40 Hydrogenated Castor oil, PEG-200 Hydrogenated Glyceryl Palmate, and PEG-150 Distearate are contained as emulsifiers. The one or more emulsifier(s) is/are contained in a total amount of 0.5 to 5.0 % by weight, preferably 1.0 to 3.0 % by weight, more preferably 1.2 to 2.0 % by weight in the composition according to the invention, in relation to the total weight of the composition.

Advantageously, the composition according to the present invention contains preservatives. All preservatives, which are allowed and suitable for cosmetic compositions may be con tained in the composition according to the invention.

However, it is preferred, if one or more paraben(s) is/are contained. Parabens are character ized by the following formula

wherein R is a linear or branched alkyl residue of 1 to 5 carbon atoms. Common parabens are methyl-, ethyl-, propyl-, butylparaben, as well as isopropyl-, isobutyl-, pentyl-, and phe- nylparaben. It is more preferred, if methyl- and/or ethylparaben are contained.

The one or more paraben(s) is/are contained in a total amount of 0.01 to 2.0 % by weight, preferably 0.05 to 1.0 % by weight, more preferably 0.1 to 0.8 % by weight in the composition according to the invention, in relation to the total weight of the composition.

It is likewise preferred, if Phenoxyethanol is contained in the composition according to the in vention. Phenoxyethanol is contained in an amount of 0.01 to 5.0 % by weight, preferably 0.05 to 3.0 % by weight, more preferably 0.1 to 0.9 % by weight in the composition according to the invention, in relation to the total weight of the composition.

It is also likewise preferred, if a combination of one or more parabene(s) and Phenoxyethanol is contained. It is more preferred, if one parabene and Phenoxyethanol are contained; it is most preferred, if methylparaben and Phenoxyethanol are contained in the composition ac cording to the invention.

Advantageously, the pH value of the composition according to the invention ranges from 6.4 to 7.8, preferably 6.8 to 7.5. The pH value may be adjusted by any physiologically acceptable means. However, it is preferred to use organic acids, selected from citric acid and/or lactic acid, more preferred citric acid to adjust the pH value.

The composition according to the invention is a foamable composition, which is provided in form of a mousse. To achieve this, the composition is contained in a packaging device, which is suited to provide the composition in form of a mousse upon removal from the packaging device.

The foamable composition according to the invention can advantageously be removed from pump atomizers (pump dispensers) which are free from propellant gas and are operated me chanically. Of particular advantage for the purposes of the present invention are pump sys tems which operate without compressed gas, but with a filter which brings about specific swirling movements.

Likewise the foamable composition according to the invention can advantageously be re moved from aerosol spraying devices. The aerosol spraying devices may be aerosol contain ers with a filling of the liquid or slurry-like substances which are under the pressure of a pro pellant. Containers of this type may be equipped with valves of very diverse constructions which allow the contents to be removed as foam. Aerosol container may be pressurized gas container.

Suitable pressurized gas containers for the purpose of the present invention are primarily cy lindrical vessels made of metal (aluminum, tinplate, contents <1000 ml), protected or shatter- resistant glass or plastic (contents <220 ml) or shattering glass or plastic (contents <150 ml), in the choice of which compressive strength and breaking strength, corrosion resistance, ease of filling, or ease of sterilizing etc., but also esthetic aspects, manageability, printing properties etc. play a role. The maximum permissible operating pressure of spray cans made of metal at 50°C is 12 bar and the maximum fill volume at this temperature is about 90% of the total volume. For glass and plastic cans, the values for the operating pressure are lower and dependent on the size of the container and the propellant (whether liquefied, com pressed or dissolved gas).

For the purposes of the present invention, cans made of tinplate or aluminum are particularly advantageous. For reasons of corrosion protection, metal cans can be coated on the inside (silver-or gold-coated), for which purpose all standard commercial internal protective coatings are suitable. For the purposes of the present invention, preference is given to polyester, epoxyphenol and polyamide-imide coatings. Film laminates made of polyethylene (PE), poly propylene (PP) and/or polyethylene terephthalate (PET) on the inside of the cans are also advantageous, in particular for cans made of tinplate.

The pressurized gas containers are usually single-part or two-part, but in most cases three- part cylindrical, conical or differently shaped. If plastics are used as the spray container ma terial, then these should be resistant to chemicals and the sterilization temperature, gas-tight, impact-resistant and stable to internal pressures in excess of 12 bar. In principle, polyacetals and polyamides are suitable for spray container purposes.

The internal construction of the spray cans and the valve construction are very varied, de pending on the intended use and the physical nature of the ingredient, e.g. whether it is in the form of a two-phase or three-phase system and can be determined by the person skilled in the art by simple exploratory investigations without inventive activity. For suitable variants, reference may be made to the "Aerosol Technologie Handbuch der Aerosol-Verpackung" (Wolfgang Tauscher, Melcher Verdag GmbH Heidelberg/Munich, 1996).

Valves, which are advantageous according to the invention, may be designed with or without dip tube. The individual components, from which valves according to the invention are usu ally constructed, preferably consist of the following materials:

• Pate: tinplate: uncoated, gold-or clear-coated, film-laminated (PE, PP or PET) alumi num: uncoated, silver-or gold-coated, different coating variants, Stoner-Mudge design;

• Gasket: natural or synthetic elastomers or thermoplastic (sleeve gaskets, film-lined made of PE or PP) internal and external seals, e.g. made of perbunan, buna, neo prene, butyl, CLB, LDPE, viton, EPDM, chlorobutyl, bromobutyl and/or diverse com pounds

• Cone: PA, POM, brass and diverse special materials, standard bores (e.g.: 0.25 to 0.70 mm or 2x0.45 to 2 x 1 .00 mm), various shaft diameters

• Spring: metal, particularly preferably V2A, stainless steel; plastic and also elastomer

• Housing: standard and impact VPH bores, RPT bores or slit for upside-down applica tions materials: e.g. polyacetal, PA, PE, POM and the like

• Dip tube: plastic (polymer resin), e.g. PE, PP, PA or polycarbonate

Advantageous spray heads for the purposes of the present invention are, for example, foam ing heads for upright use (hold can vertically) or foaming heads for upside-down application using one or more channels. For the purposes of the present invention, the content of propellant gas is chosen from the range from 0.5 to 20% by weight, preferably 1 to 10 % by weight, more preferably 3 to 8 % by weight, based on the total weight of fill material and propellant gas (corresponding to the content of 80 to 99.5% by weight, preferably 90 to 99 % by weight, more preferably 92 to 97 % by weight of fill material).

Advantageously according to the present invention one or more propellants, chosen from hy drocarbon gases, fluorinated gases, hydrofluorocarbon gases, dimethyl ether, nitrogen, air or carbon dioxide and/or mixtures thereof are contained in the composition according to the in vention. Preference is given to a blend of propellants, chosen from isobutane, propane and n-butane. More preferably a blend of 60 % n-butane, 20 % isobutene and 20% propane (% by weight) is contained in the composition according to the invention.

Brief description of the Figures

Fig. 2 shows comparative results of MUR ratios of two compositions MHAC 27 and MHAC 64.

Examples

The examples below are intended to illustrate the present invention without limiting it. The numerical values in the examples are percentages by weight, based on the total weight of the particular preparations, given as active content.

Example 1 : Compositions 1 -5

The composition according to the present invention may be prepared by any technique known or effective to prepare a cleansing composition of the kind of the present invention. The process to prepare the composition of the present invention comprises conventional for mulating and mixing techniques.

Specifically, the composition of the present invention is preferably produced with the following procedure:

1. Melt and mix components of part A in a water bath, keep the temperature at 50⁵C;

2. Melt (and mix) the component(s) of part B in a water bath, and keep the temperature at 75⁵C;

3. Mix part B and part C and keep temperature at 75 ⁵C, stir until the mixture is homoge nous and clear; 4. Mix part A with mixture of part B and C, stir until this mixture is clear and homogenous;

5. Add part D to the mixture of A, B, and C to adjust pH a value in the range of 6.8-7.5, this mixture is called“bulk”.

6. The bulk and propellant (e.g., 60 wt.% butane + 20 wt.% isobutane + 20 wt.% propane) are filled in an aerosol spraying device.

Example 2: Make-up removing efficacy

In order to prove the make-up removing efficacy an example composition according to the invention (MHAC 64, prototype) and a comparative composition (MHAC 27, benchmark) were produced.

The test procedure is illustrated in Fig. 1 , wherein

Make-up Removing (MUR) Efficacy using a Chromometer,

Removal ratio: DI_ and Aa\ (T1 - T2) / (T1 - TO) x 100,

TO: Chromometer value before application of make-up,

T 1 : Chromometer value after application of make-up,

T2: Chromometer value after using the composition MHAC 64 or MHAC 27. Results are shown in Fig. 2. It is obvious that the composition according to the invention has a significant higher make-up removing efficacy.

Example 3: RBC assay

In order to prove that the composition according to the invention is mild and non-irritative a

RBC assay was performed.

The standard RBC assay (10 minutes incubation) serves to estimate the in vivo mucous membrane of the eye irritation potential of surfactants and surfactant-containing products.

1. Hemolysis: A defined aliquot of isolated calf erythrocytes is incubated for 10 minutes while shaking at room temperature (RT) with a series of increasing concentrations of the WAS test samples to be investigated (stock solution with formulations 1 :100 w/v or 0.1% active content in PBS for raw materials). After centrifugation, the resulting super natants are analyzed photometrically at 530 nm for their liberated hemoglobin (Hb0₂) content. The relative degree of hemolysis is thereby calculated and the parameter H₅o [mI/ml] is determined from the concentration-response curve. This indicates the concen tration of the test samples at which 50% of hemoglobin is liberated.

2. Hb0₂-Denaturation: A defined aliquot of isolated calf erythrocytes is incubated for 10 minutes while shaking at RT with a fixed concentration of test sample (1% w/v or 0.1 % active content) and then centrifuged. The change in spectral absorption at 575 nm and 540 nm is measured compared to native Hb0₂. The denaturation index Dl [%] is calcu lated from the ratio of the absorption values to each other. Na lauryl sulfate serves as 100% standard (0.1 % active content).

3. L/D Quotient: The quotient is the ratio of the hemolysis parameters (H₅o) to denatura tion (Dl) and is used to characterize and classify the test samples investigated.

A composition according to the invention (MHAC#64) was analyzed by the RBC assay together with compositions containing different surfactants and higher amounts thereof and in addition a relatively high amount of glycerol (MHAC#58 and MHAC#65):

The products were made according to the following compositions:

The results obtained from the RBC assay reveal that the composition according to the inven tion is non-irritant, having by far the best L/D quotient.

Example 4: Panel test

Additionally a panel test was performed analyzing the skin compatibility of the products con taining the respective compositions. For this test, individuals (8 persons) having a sensitive skin were chosen. Said 8 persons used 8 products, 6 products contained propellants (aero sol sprays; compositions 1 , 2, 4, 5, 6, and 7) and 2 products were without propellant (pump sprays; compositions 3 and 8). Definite amounts of the compositions were applied on defined areas on the forearm. The compositions to be analyzed were left for 1 minute, 5 minutes and 15 minutes on the skin areas, before they were removed. Reactions of the skin were moni tored and analyzed. If skin reactions became apparent, they were in form of red spots/ery thema or burning/tingle. The results are summarized in the following table.

^* Only 7 test persons.

It becomes apparent that all compositions tested are well suited for the purpose they were developed for, namely to cleanse the face without causing any irritations. Face cleansing compositions are applied to the face, well distributed and then rinsed off. In general, this pro cess will not take much longer than a minute. The time periods of 5 and 15 minutes are inter vals, which are not relevant in the daily routine, but they illustrate, that the compositions ac cording to the invention (samples 5 and 8) are hardly causing any skin reaction, even after long application periods on the skin. Therefore, the compositions according to the invention are very well suited for the application on face skin, being mild and non-irritative.
