Description

Cosmetic make-up remover with improved skin moisturizing

The present invention relates to cosmetic make-up removers having improved skin moisturization comprising lanolin alcohol, one or more substances of the vitamin B group and / or the vitamin B complex, one or more oils, one or at most two gelling agents and one or more in one Oil phase dispersed polyacrylate thickener.

Mascara, eyeliners, face powders, foundations and other make-up products not only beautify the face, but also improve the user's self-esteem. A closer look at the products shows that, depending on the area of application and task, a large number of different ingredients are used. Thus, in addition to inorganic pigments, such as silicates, organic color pigments are used for coloring. The binders used include stearic acid esters and lanolin acetate. In addition, in many product types, the addition of waxes, such as beeswax or carnauba wax, and oils, such as paraffin oil, silicone oil or castor oil. Furthermore, antioxidants, thickeners,

Preservatives and other additives may be included.

Due to the variety of different ingredients, the problem arises that all applied substances must be removed without residue from the skin. Although surfactant-based cosmetic make-up removers are capable of an equivalent

To achieve cleaning performance, especially with respect to waterproof make-up. For this, however, a sufficiently high proportion of surfactant, in particular of ionic surfactants, is often necessary, which can have a negative effect on the skin compatibility in the sensitive eye area.

Alternatively, it is possible to remove waterproof make-up from the skin using cosmetic make-up removers based on a W / O emulsion. Examples of known make-up removers based on a W / O emulsion are disclosed in EP 1034774 B1 and EP1064914 B1.

A disadvantage of these, however, is that an effective and rapid application, for example under the shower where the cosmetic make-up remover is applied directly to the wet skin with your hands and then washed off with water, due to the lipophilic outer phase is limited. Therefore, the make-up remover needs are usually wiped using a cotton pad, often leaving an unpleasant, oily feeling on the skin.

Make-up remover based on an O / W emulsion, as they are known for example from US 5741766 (A), US 2006/0172904 A1 and EP1036559 A1, however, show a lower cleaning performance for waterproof components, since the oil as the inner phase of the Emulsion is present and not so fast has contact with the skin. Thus, these O / W emulsions are less suitable for removing waterproof make-up.

A disadvantage of W / O and O / W emulsions is that it is permanently stable

Mixing the two phases are often used emulsifiers. These

Emulsifiers are known to be able to deprive the human skin, in particular the horny layer, of the skin's own substances, which are responsible for the water-binding capacity of the horny layer. After initial swelling of the skin during the washing process, it is often subsequently due to a worsened water binding capacity of the horny layer to a dehydration of the skin. Furthermore, skin irritation and an unpleasant skin tension sensation may also occur.

Emulsifiers are molecules with a polar, hydrophilic structural element and a nonpolar, lipophilic structural element. In general, the emulsifiers can be defined by the HLB value (dimensionless number between 0 and 20) which indicates whether a preferred water or oil solubility is present. According to the HLB value can be

Characterize emulsifiers as follows:

HLB value Application area

0 to 3 defoamer

3 to 8 W / O emulsifier

7 to 9 wetting agents

8 to 18 O / W emulsifier

15 to 18 solubilizers

Desirable cosmetic make-up remover that can be applied easily and quickly. One way is to make cosmetic makeup

Removers in such a way that they can be applied to the wet or wet skin and rinsed with plenty of water again. It comes ideally to a gentle and thorough make-up removal. One way for this simple

Application is the application of such a make-up remover in the shower and rinsing make-up remover and make-up with the help of the shower water.

Further desirable is the use of skin care, in particular

skin-moisturizing active ingredients in such cosmetic make-up removers to prevent the skin from drying out.

Skin moisturization in the sense of the present disclosure means that the water content stored in human skin is increased. Accordingly, the use of skin-moisturized active ingredients in cosmetic cleaning products compared to

Cleaning products without these skin-moisturizing agents to an increased

Water binding capacity in human skin. As a result, a larger amount of water is stored in the skin.

The effective use of skin-care, in particular skin-moisturizing active ingredients in make-up removers, which are applied to wet or moist skin and subsequently washed off, is problematic because cosmetic make-up removers usually dissolve active ingredients and / or in solution because of their cleansing and solvating properties instead of giving it to the skin. Furthermore, many skin moisturizing agents, such as panthenol (dexpanthenol, provitamin B5), are hydrophilic, so that the active ingredient given off to the skin when washing the cosmetic make-up remover with water is largely washed off the skin again.

Due to the short duration of application of cosmetic make-up remover between the application on wet or damp skin and the subsequent rinsing with water, usually only an insufficient skin moisturization. Accordingly, there is a need for cosmetic make-up removers which, even in the case of the above-described short application, for example under the shower, allow for improved skin care, for example by improved moistening of the skin. Desirable cosmetic make-up remover, which have no sticky consistency when applied to wet skin and leave after the removal of the make-up a smooth, unstressed skin feeling.

The object of the invention was therefore to provide cosmetic make-up remover, which shows an effective skin-moisturizing effect when applied to wet skin and rinsed again after application with water. The cosmetic make-up remover not only had to be well applied to the skin, but also had a good rinsability with water. Furthermore, the task was to provide cosmetic make-up removers which have a good cleaning performance with regard to water-soluble and water-insoluble make-ups and which do not have the disadvantages of known make-up removers based on a W / O or O / W emulsion. It was another object of the invention to provide cosmetic make-up remover, which have no sticky consistency when applied to wet skin.

Surprisingly, the objects were achieved by the present invention.

The invention relates to a cosmetic make-up remover comprising

a. lanolin alcohol,

b. one or more substances of the vitamin B group and / or of the vitamin B complex,

c. one or more oils which are liquid at 20 ° C,

d. one or a maximum of two gelling agents and

e. one or more polyacrylate thickeners,

wherein the one or the maximum two gelling agents are contained in a water phase and wherein the one or more polyacrylate thickeners are dispersed in an oil phase.

The present invention also provides the use of a cosmetic make-up remover comprising

a. lanolin alcohol,

c. one or more oils which are liquid at 20 ° C,

d. one or a maximum of two gelling agents and

e. one or more polyacrylate thickeners,

wherein the one or the maximum two gelling agents are contained in a water phase and wherein the one or more polyacrylate thickeners are dispersed in an oil phase, for improved moistening of the skin.

The invention furthermore relates to the use of the make-up remover according to the invention for removing make-up, wherein the make-up remover is applied to wet and / or moist skin and rinsed off together with the make-up to be removed. The invention likewise relates to a method for removing make-up and / or moistening the skin in four steps:

1. Rinse the skin with water,

2. applying the cosmetic make-up remover according to the invention to the wet body area to be cleaned,

3. rinse off the applied cosmetic make-up remover with warm or cold water, whereby the make-up to be removed is rinsed with,

4. Drying of the skin.

The cosmetic make-up remover according to the invention contain an oil phase which is dispersed in a water phase. It has surprisingly been found that an oil phase in which polyacrylate thickeners are dispersed can be incorporated into a water phase in a storage-stable manner. It is conceivable that in the application of the product the oil phase escapes from the water phase due to the applied shear forces and thus this oil phase can provide its full cleaning performance.

The cosmetic make-up remover according to the invention can be applied well to clean the wet skin, wherein the cosmetic make-up remover have no sticky consistency and can also be rinsed well with water.

For the purposes of the invention, a cosmetic make-up remover is a cosmetic

Cleaning preparation for removing make-up.

All the following percentages by weight (% by weight), unless stated otherwise, are based on the total weight of the preparation of the cosmetic make-up remover.

If the expression "make-up remover according to the invention" is used below, this refers both to the cosmetic make-up remover according to the invention and to the cosmetic make-up remover used according to the invention.

Lanolin alcohol (a.) Is the unsaponifiable portion of wool wax comprising a mixture of alcohols having an average molecular weight of about 370 Da. Typical ingredients include cholesterol, lanosterol, agnosterol and their dihydro derivatives, as well as straight and branched chain aliphatic alcohols. For the purposes of this invention will

Particularly suitable are oils which have good compatibility in the eye area. This property is particularly advantageous for the application of make-up remover, where eye contact is often difficult to avoid.

Oil components preferred according to the invention are therefore selected from fatty acid and fatty alcohol esters. Particularly preferred in this case is isopropyl palmitate.

According to the invention, isopropyl palmitate is advantageous in a proportion of 0.1 to 30 wt.%, Particularly preferably 2 to 15 wt.%, Particularly preferably in the range of 3.5 to 7 wt , 5 wt .-% in the cosmetic make-up remover according to the invention included.

Further particularly preferred oil components are isododecane and isohexadecane. Although structurally very similar, it has surprisingly been found that isododecane contributes to improved cleaning performance. According to the invention, isododecane is advantageously present in a proportion of 0.1% by weight and 30% by weight, preferably 3% by weight and 15% by weight, particularly preferably 4.5% by weight to 10.5% by weight. -% in the inventive

contain cosmetic make-up removers.

Particular preference is therefore given to choosing one or more oils from the group of isododecane, isohexadecane and isopropyl palmitate. It is extremely preferred if the oils are exclusively isododecane, isohexadecane and isopropyl palmitate in the cosmetic make-up remover according to the invention. If isododecane and isopropyl palmitate are selected as oils, it is advantageous according to the invention if the weight ratio of isododecane to isopropyl palmitate is 3: 1 to 0.7: 1, in particular 2: 1 to 1: 1.

In a further advantageous embodiment of the invention, the oil phase may additionally contain non-polar oils, for example those selected from the group of branched and unbranched hydrocarbons, in particular mineral oil, Vaseline (petrolatum), paraffinol, squalane and squalene, polyolefins, hydrogenated polyisobutenes and C15 -19 alkane.

The total amount of oils in the cosmetic make-up removers can

surprisingly up to 35% by weight, advantageously up to 30% by weight, in particular advantageously up to 25% by weight, without causing instabilities. Instability should be understood in particular as the phenomena of phase separation, which should be avoided. These phenomena may be, for example, "oiling out", "creaming", "aggregation" or even a complete phase separation.

Furthermore, the cosmetic make-up remover according to the invention comprise one or at most two gel formers (d.) And one or more polyacrylate thickener (e.), Wherein one or the maximum of two gelling agents are contained in a water phase and wherein the one or more polyacrylate thickener in an oil phase are dispersed.

Gelling agents for the purposes of the present invention are carrageenans, agar-agar, guar-gum, hydroxypropyl methylcellulose, hydroxyethylcellulose, cetylhydroxyethylcellulose and xanthan gum.

Hydroxypropyl methylcellulose, hydroxyethylcellulose and / or xanthan gum are preferably used as gelling agents in the cosmetic make-up removers according to the invention.

Xanthan gum is a microbial anionic heteropolysaccharide produced by Xanthomonas campestris and some other species under aerobic conditions and has a molecular mass of 2 to 15 million daltons. Xanthan gum is formed from a chain of β-1,4-linked glucose with side chains. The structure of the subgroups consists of glucose, mannose, glucuronic acid, acetate and pyruvate, the number of pyruvate units determining the viscosity of the xanthan gum. It is particularly preferred if xanthan gum is included as a gelling agent in the cosmetic make-up remover according to the invention.

Furthermore, it is advantageous if, in addition to xanthan gum, no further gelling agents are present in the cosmetic make-up removers according to the invention.

Xanthan gum is available, for example, under the trade name Xanthan gum food grade, type FF from Jungbunzlauer, or from Rahn under the trade name Keltrol CG-F.

0.15 wt .-% to 0.5 wt .-%, particularly preferably 0, 17 wt .-% to 0.3 wt .-%.

Preferred polyacrylate thickeners to be selected according to the invention are sodium polyacrylate, acrylates / C10-30 alkyl acrylate crosspolymer and / or ammonium

Acryloyldimethyltautrate / beheneth-25 methacrylate copolymer.

Particularly preferred is the use of sodium polyacrylate in the cosmetic make-up remover according to the invention. It has been found that cosmetic make-up removers with acrylates / C10-30 alkyl acrylate crosspolymer as polyacrylate thickener according to the invention have a poorer storage stability compared with inventive cosmetic make-up removers with sodium polyacrylate as polyacrylate thickener. Furthermore, it has been found that cosmetic make-up remover according to the invention with ammonium acryloyldimethyltautrate / beheneth-25 methacrylate copolymer as

Polyacrylatverdicker compared to inventive cosmetic make-up removers with sodium polyacrylate as Polyacrylatverdicker have a poorer cleaning performance. Sodium polyacrylate is known under the INCI name Sodium Polyacrylate and, for example, under the trade name Cosmedia® SP from BASF.

It is particularly advantageous for the purposes of the invention if the polyacrylate thickener exclusively contains sodium polyacrylate in the cosmetic make-up removers. The cosmetic make-up remover according to the invention contain one or more total Polyacrylatverdicker in a proportion of 0.3 wt .-% to 2 wt .-%, in particular 0.6 wt .-% to 1, 3 wt .-%.

The cosmetic make-up remover according to the invention are preferably preferred

Considering the following three steps:

1 . The one or two gelling agents are dispersed in the water phase

2. The polyacrylate thickener is dispersed in the oil phase

3. The oil phase is introduced into the water phase and emulsified.

It is conceivable that by the dispersion of the polyacrylate thickener in the oil phase, the oil phase remains liquid and the consistency of the oil phase does not turn into a gel. The oil phase is thus more spreadable and can be better distributed on the skin. In contrast to many prior art formulations, no sticky or waxy residue on the skin that is adversely affected by the user is produced.

In contrast, both the gelling agent and the polyacrylate thickener in the

Water phase introduced and the oil phase remains without further thickening agents, then the cosmetic make-up remover becomes unstable after some time.

Advantageously, the oil phase of the cosmetic make-up remover according to the invention may additionally comprise one or more carbomers. Carbomers are homopolymers of acrylic acid crosslinked with pentaerythrol allyl ether, sucrose allyl ether or an allyl ether of propylene. These carbomers are for the purposes of the invention in no way as

Polyacrylatverdicker or gelling agent referred.

Carbomers are sold, for example, by the company Lubrizol Advanced Materials under the trade name Carbopol 980 and / or Carbopol 981.

Carbomers are advantageously contained in a total amount of 0.25 wt .-% to 1 wt .-% in the cosmetic make-up remover according to the invention.

In an advantageous embodiment of the invention, the cosmetic make-up remover according to the invention additionally comprise one or more starch compounds, in particular tapioca starch, which improve the sensory properties of the cosmetic make-up remover. Tapioca starch is available, inter alia, under the trade name Tapioca Pure from Akzo Nobel.

The proportion of starch compounds in the cosmetic make-up remover according to the invention is advantageously 0, 1 wt .-% to 8 wt .-%, in particular 1 wt .-% to

3% by weight.

In addition to the described gelling agents, polyacrylate thickeners, carbomers and

Starch compounds are not celluloses in the cosmetic make-up remover according to the invention and no cellulose derivatives and advantageously no further

Polysaccharides, in particular no further thickening agents. Celluloses and cellulose derivatives within the meaning of the invention include all substances which comprise a cellulose unit. Cellulose units are polymers made up of the monomer cellobiose. Cellobiose consists of glucose units linked by a β-1,4-glycosidic bond.

For the purposes of the present invention, no further substances means that the proportion of these substances is below 0.1% by weight. The mentioned small amounts of substances can, for example, reach the cosmetic make-up remover from the manufacturing process.

Thickeners or thickening substances in the context of the invention are those substances which increase the viscosity of the preparation or phase compared to preparations without this substance.

In the development of suitable cosmetic make-up remover, it has been found that an increase in the proportion of thickening agent contributes to improving the stability of the make-up remover, but at the same time a deterioration of the cleaning performance occurs.

Surprisingly, it has been shown that a formulation of the invention

Cosmetic make-up remover can be made without the addition of emulsifiers and these emulsifier-free cosmetic make-up remover have storage stability. Nevertheless, it is advantageous for the purposes of the present invention, when the

cosmetic make-up remover according to the invention additionally a minimal

Emulsifier content included. A minimum amount of emulsifier in the context of the invention means that one or more emulsifiers in a total amount of from 0.05% by weight to 1% by weight, preferably from 0.1% by weight to 0.5% by weight. %, more preferably 0.15 wt .-% to 0.25 wt .-% in the cosmetic make-up remover according to the invention are included.

When a minimum amount of emulsifier is used, in particular cosmetic make-up removers having an oil content of more than 18% by weight have an improved storage stability, without at the same time negatively influencing the cleaning performance of the make-up remover. It can be assumed that the oil components in the

Cosmetic make-up remover according to the invention are present so that they can make an effective contribution to the cleaning.

Emulsifiers preferred according to the invention have an HLB value in the range from 10 to 15. Examples of these inventively preferred emulsifiers include polyglyceryl stearate, sodium stearoyl glutamate, glyceryl stearate citrate and / or

Polyglyceryl-3 methyl glucose distearate. Particularly preferred is the use of

Polyglyceryl-3 methyl glucose distearate as emulsifier. Polyglyceryl-3 methyl glucose distearate is available under the trade name Tego® Care 450 from Evonik Industries.

Advantageously, the cosmetic make-up remover according to the invention additionally contain one or more fatty alcohols, which improve the stability of the cosmetic make-up remover. For the purposes of the invention, fatty alcohols are by no means to be referred to as emulsifiers or oils.

Skin moisture was measured by means of capacitance measurements of a corneometer (Corneometer CM 825 from Courage + Khazaka, Cologne, Germany). All measurements were carried out at a room temperature of 21 ° C and a relative humidity of 50%.

For the measurement, two areas of the forearm were selected, one remaining untreated throughout the study. Before applying the cosmetic make-up

Remover was a reference measurement tO performed in the untreated test area. This reference measurement (measurement of the initial permittivity tO) was used to record a baseline for subsequent measured values. Subsequently, the

Forearm area rinsed under running water for 5 seconds. The cosmetic make-up remover was then applied to the selected area (2 μΙ_ per cm ² ) and washed for 30 seconds in circular motions. The make-up remover was then washed under running water for 10 seconds and the area was blotted dry with a towel (not rubbed). Skin moisture was measured for 5 minutes (t1) and 2 hours (t2) after application in the treated and untreated test area.

For the evaluation of the obtained measured values after 5 minutes and 2 hours, the measured initial permittivity t0 was subtracted from the respective measured values t1 and t2. A positive increase in the difference means an improved one

Skin moisture. For the determination of the skin-moisturizing effect of the make-up remover according to the invention, the example formulation 3 was prepared once as indicated, once without panthenol (panthenol replaced with water) and once without lanolin alcohol (lanolin alcohol replaced with water).

The results obtained are shown in the table below and in Figure 1. Both 5 minutes and 2 hours after application, a significantly increased skin moisture (positive deviation from the initial value) can be detected on the test area treated with the cosmetic make-up remover according to the invention (example formulation 3). Thus, the cosmetic make-up remover according to the invention shows skin-moisturizing action.
