Description
Technical Field
The present invention relates to a composition, in particular a cosmetic composition for caring for/making up keratin materials, in particular the skin and the lips, and more particularly a cosmetic composition of the emulsion type, which exhibits an optimized rinsability effect and, at the same time, is capable of protecting the keratin materials from the harmful effects caused by the sun.
Background
Keratin materials such as skin, scalp and hair are constantly exposed to a number of harmful environmental agents including UV radiation, air pollutants such as ozone and ionizing radiation, which produce Reactive Oxygen Species (ROS), wherein exposure to the sun has created a number of harmful problems with keratin materials such as sunburn and aging caused by UV rays and pro-oxidants.
UVB rays (having short wavelengths and being highly energy intensive) are responsible for sunburn of the skin. UVA radiation is less energy intensive than UVB radiation, but the amount is 20 times greater than UVB radiation.
Thus, the deleterious effect of UV light on keratin materials affects the cellular respiration of these keratin materials and causes accelerated aging of the skin, resulting in dull skin tone and premature formation of wrinkles and fine lines, and a reduction in hair strength also resulting in a dull appearance. In addition, UV rays can cause irritation and allergic phenomena as well as inflammation on the skin.
In order to combat UV radiation, various compositions comprising UV filters are described. However, there remains a need for new compositions for protecting keratin materials from the harmful effects caused by exposure to the sun, which compositions have the desired Sun Protection Factor (SPF) value, and improved antioxidant effects and are stable over time.
However, in order to have the required protection against UV rays, i.e. high SPF and PPD values, high amounts of organic or inorganic UV filters are required in conventional products. Removal of the product itself is time consuming and inconvenient. Furthermore, consumers often feel greasy residues remaining on the skin even after use of makeup remover.
Thus, there remains a need to find stable care and/or make-up products which exhibit an optimized water washability effect and at the same time have a good UV protection effect on keratin materials.

Advantageously, the hydrophilic pigment according to the invention is a treated or untreated iron oxide and/or titanium dioxide.
The term "pearlescent pigment" or "nacres" is to be understood as meaning any form of colored particles which may or may not be iridescent, in particular produced by certain molluscs in their shell, or alternatively synthetic, and which have a color effect via optical interference.
The nacres can be chosen from pearlescent pigments, such as titanium mica coated with iron oxide, titanium mica coated with bismuth oxychloride, titanium mica coated with chromium oxide, titanium mica coated with organic dyes and also pearlescent pigments based on bismuth oxychloride.

In another particular embodiment, the hydrophilic pigment is a treated hydrophilic pigment, i.e., a pigment that has been hydrophilized surface treated with any of the treating agents commonly used to impart hydrophilic properties to pigments. In general, the hydrophilic organic agent used for the surface treatment of the material in order to optimize its dispersibility in aqueous media is more particularly chosen from biopolymers, carbohydrates, polysaccharides, polyacrylates and polyethylene glycol derivatives. The material so treated may be dispersed in the absence of a solvent-soluble medium, such as water. As an example of a biopolymer to be used for coating the dye to be dissolved according to the present invention, mention may be made of polymers based on carbohydrate type monomers. More particularly, bioglycan gums, chitosan and derivatives thereof, such as butyloxy chitosan, carboxymethyl chitosan, carboxybutyl chitosan, chitosan gluconate, chitosan adipate, chitosan glycolate, chitosan lactate and the like, chitin and derivatives thereof, such as carboxymethyl chitin, chitin glycolate; cellulose and its derivatives, such as cellulose acetate; microcrystalline cellulose; phosphoric acid double starch; sodium hyaluronate; a soluble proteoglycan; galactose arabinan; a glycosaminoglycan; glycogen; sclerotium rolfsii gum; (ii) a glucan; starch and its derivatives; and mixtures thereof.

The surfactant can be absorbed or adsorbed onto the pigment by solvent evaporation, chemical reaction, and creation of covalent bonds.
According to one description (version), the surface treatment comprises a coating of a pigment.
The coating may represent 0.1 to 10 weight percent and more particularly 1 to 5 weight percent of the total weight of the coated pigment.
Before incorporation of the pigment into the other ingredients of the care or make-up composition, it is possible, for example, to carry out the coating by allowing a liquid surfactant to adsorb to the surface of the pigment, by simply mixing the pigment and said surfactant with stirring, optionally under heating conditions (hot conditioning).
The coating can be performed, for example, by a chemical reaction of the surfactant with the surface of the pigment and creating a covalent bond between the surfactant and the pigment. Such a process is described in particular in patent US 4,578,266.

In vivo SPF test, Sun Protection Factor (SPF) of the formulation such as FDA Sunscreen product Final regulation (sun Final Rule); CFR 21 pieces 201 and 310 section [ file number: FDA-1978-N-0018] (formerly document No.: 1978N-0038), RIN 0910-AF43, Labeling and validation Testing (Labeling and Effect Testing); sunscreen drugs For Over-the-Counter Human Use [ FR doc.2011-14766, 06/16/2011 filing; date of publication: 06/17/2011] was evaluated on human skin using a xenon arc solar simulator as a UV source as defined.
In vivo PPD testing of the formulations was performed according to the UVA Protection effectiveness Measurement standard (Measurement Standards for UVA Protection effectiveness) issued by the Japan chemical Industry Association (Japan Cosmetic Industry Association) -J.C.I.A. -21.11.1995 and validated at 1.1.1996. The UVAPPD sun protection factor (UVAPPD SPF) is mathematically represented by the ratio of the UV-A radiation dose (MPPDp) required to reach the pigmentation threshold with a UV-screening agent to the UV-A radiation dose (MPPDn) required to reach the pigmentation threshold without a UV-screening agent.
The water washability effect of the recipe was performed with a color sphere (Chromasphere) having a resolution of 410x410 pixels according to the following scheme:
measurements were made in a standardized manner at 20 ℃ before and after application of the composition to the skin of a model with bare fingers, washing with tepid water after application (for evaluation of water washability effect).
Instrumental measurement protocol for Water washability Effect
Colorimetric measurements of the skin before and after makeup were made by measuring the average of the plane (planes), C (chroma, distance from neutral axis-saturation), H (hue, angle/direction in the range of 360 degrees) and L (lightness) of 10 female models, respectively. For each bit of the 10-bit female model, an image was acquired using a color sphere having a resolution of 410x410 pixels. The results are expressed in the following manner: colors were quantified by C (chroma, distance from neutral axis-saturation), H (hue, angle/direction in the range of 360 degrees) and L (brightness) analyzed by the camera. By variation of these variables (. DELTA.E) after 3 hours of makeup94) Homogeneity and persistence (long lasting) were calculated. Δ E, dE or Δ E94Is defined as a measure of the difference between the two colors. The CIE technical Commission (TC 1-29) published the formula shown below in 1995:
wherein:
KL、K1and K2Is a weighting factor;
L1*、C1h and1is the coordinate in the chromaticity space (colorimetric space) of the first color to be compared, and L2*、C2H and2is the coordinate of the second color in the chromaticity space.
A measurement of the effect of water washability was made and made at the following times:
T10minmeasured after 10 minutes of application of the composition
T20minMeasurement 20 minutes after washing the skin to which the composition is applied with tepid water
(T10min–T0) And (T)20min–T0) Measurement of Water washability of the composition
Measurements were performed on a panel of 10 female models, which were left in an air-conditioned (22 ℃ +/-2 ℃) waiting room for 15 minutes before the test began. They removed their makeup and acquired an image of one of their cheeks using a ball having a resolution of 410x410 pixels. This image makes it possible to measure T before applying makeup0The color of the light. Approximately 10mg of inventive compositions 1 and 2 and comparative compositions 1, 2 and 3 were then weighed into a petri dish and applied with a bare finger, respectively, thereto for T0The area measured was 12.56cm2On the facial skin.
After 10 minutes drying time, images of the cosmetic cheek area were taken using a color sphere. This image makes it possible to measure the colour (T) immediately after application of makeup10min). The makeup cheeks were then washed with lukewarm water. Finally, an image of a clean cheek region after waiting 20 minutes after washing the makeup cheek region was acquired using a color sphere. This image makes it possible to measure the colour (T) after washing the makeup cheek area20min)。
The results are expressed by the following equation:
difference (%) ═ o (Δ E)94(T10min-T0)-ΔE94(T20min-T0)]/ΔE94(T10min-T0)﹜×100%
The higher the difference (%) is, the better the water washability of the composition is. If the difference is more than 80%, preferably more than 85%, the product exhibits excellent water washability. If the difference is below 70%, the product does not have an acceptable water washability effect.
