Description

COMPOSITION IN FORM OF AN EMULSION

TECHNICAL FIELD

The present invention relates to a composition, especially cosmetic composition for caring for/making up the keratin materials, especially the skin and the lips, and more particularly a cosmetic composition of emulsion type, exhibiting optimized water washability effect, and meanwhile maintaining good make up effect.

BACKGROUND ART

Cosmetic compositions for caring for/making up keratin materials, especially the skin and the lips, more especially the skin, also known as foundations, concealers, or tinted creams, are commonly used to give an aesthetic color to the skin, for example, to the face, in order to conceal skin imperfections such as redness and spots.

For centuries, consumers around the world, especially in Asia, are in search of novel cosmetic products for improving the appearance of keratin materials and especially the skin, in particular the surface appearance (visible and/or tactile unevenness) and/or the skin complexion, an external sign of a healthy glow, health and youth.

These goals can be achieved by applying to the skin the conventional foundations.

US2005/0008592 discloses a foundation in the formula of a water-in-oil emulsion comprising a fatty phase, an aqueous phase, at least one surfactant chosen from C₈-C₂₂ alkyl dimethicone copolyols, at least one other surfactant chosen from dimethicone copolyols and a mixture of volatile oils in a large amount (more than 6%).

US2005/0002890 also discloses a fluid cosmetic composition in the form of a water-in-oil emulsion comprising a liquid fatty phase, an aqueous phase, a dimethicone copolyol and a C₈- C₂₂ alkyldimethicone copolyol, characterized in that it comprises solid particles of polymethyl methacrylate and in that the liquid fatty phase comprises volatile hydrocarbon-based oil, the said composition being free of cyclotetrasiloxane.

However, the conventional products as such raise concerns of the consumers in the following aspects:firstly, pigments containing in the foundation may cause clogging issue to the skin pores; secondly, removing of the foundation is time consuming and a cause of skin keratinization; thirdly, residues remain on skin even after using makeup removal. Thus there exists a need for a novel composition to solve the issues aforementioned.

Conventional oil-in-water type foundation/tinted creams are developed to solve the water washability issue. However this type of compositions can only be partly removed by water, therefore exhibits poor water washability. Besides, the compositions as such lack of long-lasting make up effect due to its hydrophilic property.

Therefore there remains the need to find stable care and/or makeup products, which exhibits an optimized water washability effect, and at the same time possesses good make up effect, for example homogeneous and long-lasting make up effect.

DISCLOSURE OF INVENTION Such a composition can be obtained using at least one first surfactant chosen from alkyl dimethicone copolyols, at least one second surfactant chosen from dimethicone copolyols, which is different from the first surfactant, at least one third surfactant which is different from the first or the second surfactant, having a HLB value of greater than or equal to 8, and at least one hydrophilic pigment. Consequently, according to a first aspect, the subject of the present invention is a composition in form of an emulsion, comprising at least one fatty phase, and at least one aqueous phase, and: a) at least one first surfactant chosen from C₈-C₂₂ alkyl dimethicone copolyols;

b) at least one second surfactant chosen from dimethicone copolyols, which is different from the first surfactant a);

c) at least one third surfactant which is different from the first or the second surfactant a) or b), having a HLB value of greater than or equal to 8; and

d) at least one hydrophilic pigment.

According to a preferred embodiment, the composition of the present invention is in form of a multiple emulsion, such as water-in-oil-in-water emulsion, or oil-in-water-in-oil emulsion, preferably an oil-in-water-in-oil emulsion.

In a preferred embodiment, the present invention comprises at least one filler, organic or mineral, chosen from modified or unmodified starch, preferably modified starch, such as acetylated oxidized starch. According to a preferred embodiment, the present invention comprises at least one thickener, polymeric or mineral, preferably chosen from hydrophilic thickeners, lipophilic thickeners, or a mixture thereof. More preferably the thickener is chosen from polysaccharide biopolymers, lipophilic clays, hydrophobic silicas, or a mixture thereof, more preferably the thickener is chosen xanthan gum, disteardimonium hectorite, silica silylate, or a mixture thereof.

In another aspect, the present invention is also directed towards a process for caring for/making up the skin, in particular the face, characterized in that it comprises the application to the skin of at least one composition in accordance with the invention.

The current invention as described above is stable over time at room temperature (25 'Ό), for example, after storage for 2 months, and further, for example, for 4 months.

The present invention provides good make up effect to the skin, such as homogeneous make up effect on the skin, and long lasting make up effect on the skin.

More importantly, the present invention possesses an optimized water washability property.

By "water washability" it intends to mean the washable ability of the present composition when using water for rinsing off from the skin.

The term 'pearlescent pigments' or "nacres" should be understood as meaning coloured particles of any form, which may or may not be iridescent, especially produced by certain molluscs in their shell, or alternatively synthesized, and which have a colour effect via optical interference.

The nacres may be chosen from nacreous pigments such as titanium mica coated with an iron oxide, titanium mica coated with bismuth oxychloride, titanium mica coated with chromium oxide, titanium mica coated with an organic dye and also nacreous pigments based on bismuth oxychloride. They may also be mica particles at the surface of which are superposed at least two successive layers of metal oxides and/or of organic dyestuffs.

Example 2: evaluation example Evaluations of the makeup effect such as homogeneity and long lasting, and water washability effect of the invention compositions 1 and 2 and comparative compositions 1 , 2, and 3 prepared above were performed, by means of Chromasphere with a definition of 410x410 pixels, according to the following protocol: the measurements were taken in a standardized manner at 20°C, before and after application with the bare fingers (for makeup effect evaluation), or washing with lukewarm water after application (for water washability effect evaluation), of the composition onto the skin of a model.

Evaluations of the above mentioned effects of the compositions were also performed by the panelists.

• Protocol for instrumental measurements of the makeup effect and water washability effect

A colorimetric measurement of the skin before and after making up was carried out by measuring the means for the planes of 10 women models, C^* (chroma, the distance out from the neutral axis - saturationv), H^* (hue, the angle/direction in the 360 degree range), and L* (lightness), respectively. For each of the 0 women models, an image was taken using a

Chromasphere with a definition of 410 χ 410 pixels. The results were expressed in the following manner: the color was quantified by the C^* (chroma, the distance out from the neutral axis - saturationv), H* (hue, the angle/direction in the 360 degree range), and L^* (lightness) analysed by the camera. The homogeneity and long lasting were calculated by the variation of these variables after 3 hours of makeup (deltaE₉₄). The deltaE, dE or else ΔΕ₉₄ is defined as a measurement of difference between two colors. The formula was published in 1995 by a technical committee of the CIE (TC 1-29), as shown below:

where in:

*— T *— T *

AC^ = c - c; K|_, Ki and K₂ are weighting factors;

Li*, Ci* and H i * are the coordinates in the colorimetric space of the first color to be compared and L₂*, C₂* and H₂* those of the second.

More specifically, the measurements of makeup effect (homogeneity and long lasting) were carried out and the measurements were made at the following times:

T₀ = measurement on naked skin freed of makeup, before application of the test composition

T_imm = measurement after application and drying (10 minutes) of the test composition

T_3h = measurement 3 hours after application of the composition

(Timm - T₀) measurement of the homogenity of the composition (T_3h - Timm) measurement of the long lasting of the composition

The measurements were performed on a panel of 10 women models who were kept in an air- conditioned (22 <C +/- 2 <C) waiting room for 15 min before the beginning of the test. They removed their makeup and an image of one of their cheeks was acquired using the Chromasphere with a definition of 410 ^χ 41 0 pixels. This image made it possible to measure the color at T₀ before applying makeup. Approximately 100 mg of the invention compositions 1 and 2, and the comparative compositions 1 , 2, and 3 formulated in the formulation example were then weighed out into a watch glass and were applied with the bare fingers, respectively, to the half of the face on which the measurement was carried out at T₀.

Right after application of the compositions, an image of the made-up cheek was acquired using the Chromasphere. This image made it possible to measure the color immediately after applying the compositions (T_imm). The women models then returned to the air-conditioned room for 3 hours. Finally, an image of the made-up cheek after waiting for 3 hours was acquired using the Chromasphere. This image made it possible to measure the color after wearing the compositions for 3 h (T_3h). Each image obtained using the camera was processed by coxellography. The standard deviation of each monochrome plane was calculated. The product of the three standard deviations was equal to the coxellographic index. This parameter was used for the statistical calculation. The more uniform the skin, the smaller the standard deviation. The coxellographic index changes in the same way since it is the product of the standard deviations of the three planes C^* (chroma), H^* (hue), and L^* (lightness).

The results were expressed by calculating the difference (T_imm - T₀), which measures the homogeneity, and the difference (T_3h - T_imm) measures the long lasting.

For the measurements performed, it was considered that:

+ poor homogeneity or no long lasting effect;

++ good homogeneity or good long lasting

+++ very strong homogeneity or very good long lasting The measurements of water washability effect were carried out and the measurements were made at the following times:

T_{1 0}min = measurement 10 minutes after application of the composition 2omin = measurement 20 minutes after washing the skin where the composition is applied on by the lukewarm water (T_{1 0}min - T₀) and (T_20min - T₀) measurement of the water washability of the composition

The measurements were performed on a panel of 10 women models who were kept in an air- conditioned (22^<C +/- 2^<C) waiting room for 15 min before the beginning of the test. They removed their makeup and an image of one of their cheeks was acquired using the Chromasphere with a definition of 410 χ 410 pixels. This image made it possible to measure the color at T₀ before applying makeup. Approximately 10 mg of the invention compositions 1 and 2, and the comparative compositions 1 , 2, and 3 were then weighed out into a watch glass and were applied with the bare fingers, respectively, to the face skin of a 12.56 cm² area on which the T₀ measurement was carried out.

After a drying time of 10 min, an image of the made-up cheek area was acquired using the Chromasphere. This image made it possible to measure the color immediately after applying makeup (T_{1 0m}in) - Then the made-up cheek was washed by lukewarm water. Finally, an image of the cleaned cheek area after waiting for 20 minutes after washing of the made-up cheek area was acquired using the Chromasphere.This image made it possible to measure the color after washing of the made-up cheek area (T_20min)-

The results were expressed by the following equation:

Difference (%) = { [ΔΕ ₉₄ (T_{1 0m}in^— T₀)— ΔΕ₉₄ (T₂omin^— T₀)] / ΔΕ₉₄ (T_{1 0min} -To) > X 100% The higher the difference (%) is, the better the water washability of the composition. The products exhibit excellent water washability if the difference is greater than 80%, preferably greater than 85%. The products do not possess an acceptable water washability effect if the difference is lower than 70%.
