Description

Solid water in silicone composition with water release effect
The present invention relates to the field of making up and/or caring for the keratinic materials, in particular the skin, and is targeted, in particular at providing solid cosmetic compositions, in particular solid foundation in the form of water-in-silicone emulsion.
The present invention also relates to a method for making up and/or caring for the skin, more particularly the face or neck, using these solid cosmetic compositions according to the present invention.
Foundation compositions are commonly used to contribute to an attractive color of the skin, in particular the face, but also to conceal imperfections of the skin, such as red blotches or blemishes. Conventional foundations exist in both fluid and solid forms, and each possesses its own advantages due to its form. In general, consumers are attracted by a cosmetic composition, especially a foundation, which is easy to use and brings to the skin a good sensory.
By “easy to use” we intend to mean the composition is easy to carry with and to apply on the skin.
By “sensory” we intend to mean a water release effect, a cooling effect, and a melting effect. The water release effect refers to a very fresh feeling via the water droplets on keratin materials in particular the skin and a long time moisturization; the cooling effect refers to a feeling of immediate temperature decrease on the keratin materials after application of a composition; and melting effect refers to a texture change solidity to fluidity when applying a composition on keratin materials.
Efforts have been made to develop cosmetic compositions with these properties.
The patent application WO 2012/145862 discloses fluid foundation compositions in the form of a water-in-silicone emulsion, comprising a fatty phase, an aqueous phase and at least one organopolysiloxane elastomer, at least one dimethicone copolyol, at least one C8-C22 alkyl dimethicone. The fatty phase comprises at least one volatile oil and/or at least one non-volatile oil and optionnaly at least one wax.
However, the foundations of the prior art, due to their fluid form, is found not easy to carry with and apply on the skin.
Besides, the skin sensory after applying on the skin is still to be improved.
Therefore, there is a need for developing solid cosmetic compositions, such as solid foundation compositions.
In particular, there is a need for developing solid cosmetic compositions which are easy to carry with and to apply on the skin, with the fingers or an applicator by the users.
There is also a need for developing a solid cosmetic compositions for the skin that, when applied on the skin and more particularly on the face and/or neck, allow a good sensory, i.e., water release effect , cooling sensory, and moreover melting effect, while presenting a good stability over time and temperature variations.
The present invention aims to provide a solid cosmetic composition, in particular a solid foundation composition, in the form of a water-in-silicone emulsion.
The present invention also aims to provide a solid cosmetic composition, in particular a solid foundation composition, in the form of a water-in-silicone emulsion, which is easy to carry with and apply on the skin, with the fingers or an applicator by the users, presenting a good stability over time and temperature variations.
Another aim of the present invention is to provide a solid cosmetic composition, in particular a solid foundation composition, in the form of a water-in-silicone emulsion, that when applied on the skin and more particularly on the face and/or neck, allow good skin sensory, i.e., water release effect, melting effect, and cooling sensory, while presenting a good stability over time and temperature variations.
Thus, the present invention concerns a solid cosmetic composition in the form of a water-in-silicone emulsion, comprising a solid fatty phase, and an aqueous phase, and
(i) at least one silicone elastomer,
(ii) at least one dimethicone copolyol,
(iii) at least one (C8-C22) alkyl dimethicone,
(iv) at least one wax having a melting point of greater than or equal to 60℃, and
(v) at least one solid fatty substance selected from C18-C30 alkane, solid ester of fatty acid and of fatty alcohol, or a mixture thereof.
Surprisingly, the inventors have discovered that the composition according to the invention provides a good water release effect, melting effect, and cooling sensory while presenting a good stability over time and temperature variations.
More surprising, it has been observed that, the combination of at least one wax having a melting point greater than or equal to 60℃ and at least one solid fatty substance  improves the melting and cooling sensory and the stability over time and temperature variations.
The invention also concerns a cosmetic method for caring and/or making up the skin, comprising the application of a composition of the invention on a keratin material.
The inventors have indeed found that the cosmetic compositions according to the invention prove to be easy to carry with, very easy to apply to the skin, to cover uniformly the skin and provide the user with a feeling of freshness and a long time moisturization after application. In addition, they are very thin and light, and prove to have a very good balance of skincare efficacy perception (fresh and moisturization) as well as make-up efficacy (proper coverage) .
The cosmetic composition according to the invention is a foundation preferably under the form of compact emulsion or cast solid products.
Within the meaning of the present invention, the term “solid” refers to the composition, which does not flow under its own weight at room temperature (25℃) .
Within the meaning of the present invention, the term ″solid emulsion” means that the emulsion does not flow under its own weight at room temperature (25℃) after 1 hour.
The term "solid" composition means a composition which hardness at 20℃ and at atmospheric pressure (760 mmHg) is greater than or equal to 30 Nm-1 when it is measured according to the protocol described below.
The hardness of a solid composition is measured according to the following protocol. The composition whose hardness is to be determined is stored at 20℃ for 24 hours before measuring the hardness.
The hardness may be measuren at 20℃ via the “cheese wire” method, which consists in transversely cutting a wand of product, which is preferably a circular cylinder, by means of a rigid tungsten wire 250 μm in diameter, by moving the wire relative to the stick at a speed of 100 mm/minute.
The hardness of the samples of compositions of the invention, expressed in Nm-1, is measured using a DFGS2 tensile testing machine from the company Indelco-Chatillon. The measurement is repeated three times and then averaged. The average of the three values read using the tensile testing machine mentioned above, noted Y, is given in grams. This average is converted into Newtons and then divided by L which represents the longest distance through which the wire passes. In the case of a cylindrical wand, L is equal to the diameter (in metres) .
The hardness is converted into Nm-1 by the equation below:
(Y × 10-3 × 9.8) /L
For a measurement at a different temperature, the stick is stored for 24 hours at this new temperature before the measurement.
In everything which follows or which precedes, the term "silicone" is understood to denote, in conformity with what is generally accepted, any organosilicon polymer or oligomer with a branched or crosslinked and linear or cyclic structure of variable molecular weight obtained by polymerisation and/or polycondensation of suitably functionalised silanes and essentially composed of a repetition of main units in which the silicon atoms are connected to one another via oxygen atoms (siloxane bond ≡Si-O-Si≡) , optionally substituted hydrocarbon radicals being directly bonded via a carbon atom to the said silicon atoms. The commonest hydrocarbon radicals are alkyl radicals, in particular C1-C10 alkyl radicals and especially methyl radicals, fluoroalkyl radicals and aryl radicals, in particular phenyl radicals. They can, for example, be substituted by C1-C40 ester or ether groups or C7-C60 aralkyl groups.

The invention is illustrated in more details in the following examples.
Example 1
Water-in-silicone emulsion foundations conformed to the invention had been prepared from the following composition (the percentages are expressed in weight by weight of the total composition and the Active Material percentage (MA) is precised when required) :
Figure PCTCN2015080239-appb-000018
Figure PCTCN2015080239-appb-000019
The formulas listed above were prepared according to the following steps:
Phase A was weighed together and was heated to 80℃ while stirring using a Moritz-type stirrer, until the phase was homogenous;
Phase B were heated to 80℃
Phase B was slowly added to phase A while stirring using a Moritz-type stirrer and while retaining, during the addition, a minimum temperature of 75℃.
Then the invention formulas 1 to 4 were casted, respectively, and homogeneous compact foundations were obtained; whereas the comparative formulas 1 to 2 were filled in tubes to obtain the foundation products.
The Compositions of the invention 1 to 4, respectively, were also tested on users. The easiness to use, and the skin sensory, such as water release effect, cooling effect, and melting effect of the compact foundations 1 to 4 obtained from the Compositions of the invention were evaluated by 12 consumers, by applying 0.1 g of the compact foundations obtained from the Compositions of the invention 1 to 4, respectively, on the inner forearms. The consumers were asked to observe the water release effect while applying the foundations, and to evaluate the cooling effect and the melting effect at the same time.
It has been observed a significant difference between an area of the skin treated with this emulsion compared with an untreated area, said treated skin being better moisturized than said untreated skin.
All prepared emulsions have good stability, i.e. viscosity and appearance of bulk kept well but it is observed that the stability of those emulsions decreases with the diminution of the quantity of Cetyl PEG/PPG-10/1 dimethicone in said emulsions. Thus, the emulsion of composition 2 has a better stability than the emulsion of composition 3, itself having a better stability than the emulsion of composition 4, which had slightly water release on surface of the emulsion.
Example 2
The stabilities, easiness to use, and the skin sensory of the invention formulas and the comparative formulas were evaluated.
The stabilities of the Compositions of the invention formulas and the comparative formulas were evaluated at 45℃, 37℃, and 4℃ for 8 weeks.
The invention and comparative formulas listed above, respectively, were also tested on users. The stabilities, easiness to use, and the skin sensory, such as water release effect, cooling effect, and melting effect of the invention and comparative formulas were evaluated by 12 consumers, by applying 0.1 g of the formulas, respectively, on the inner forearms. The consumers were asked to give scores to the effects to be tested. 5 stands for excellent, 4 stands for very good, 3 stands for acceptable, 2 stands for poor, not acceptable, and 1 stands for very poor. The results are as follow:
Figure PCTCN2015080239-appb-000020
It was observed that, the invention formulas 1 to 4, due to their solid textures, were easily casted as a compact foundation, which enabled the consumers to use with either single hand or applicators for making up the skin. It was very convenient for the consumers to supplement the makeups of the skin during the day. Whereas the comparative formulas 1 and 2, placed in tubes due to their liquid texture, are not easily applied on the skin. They required consumers to use both hands for application.
In terms of skin sensory, it was observed that the invention and comparative formulas have good water beads release effect and cooling effect. The invention formulas 1 to 4, comparing to the comparative formulas 1 and 2, have improved melting effect, due to the fact that during application, the invention formulas, which were solid, changed to liquid texture on the skin.
Finally, it was observed that the invention formulas and the comparative formulas have good stability at different temperatures.
