Description

Anhydrous composition with non-sticky feeling TECHNICAL FIELD
The present invention relates, in general, to an anhydrous composition for application onto a targeted substrate. More particularly, the present invention relates to an anhydrous composition possessing an improved non-sticky feeling when applying on the targeted substrate, in particular keratin materials.
BACKGROUND OF THE INVENTION
Compositions for caring for and/or making up the skin and/or the lips are produced to satisfy the need of conditioning and/or making up of the skin and the lips. In particular, consumers are looking for a product for caring for and making up the lips, with good conditioning of the lips, such as moisturizing, shining; good makeup effect, such as homogeneous and long-lasting color effect on the lips, and easy usage, such as easy spreading, good pay-off on the lips.
Efforts have been made to achieve that need. It is known to formulate products such as lip gloss, lip oil, or other types of liquid anhydrous compositions for the purpose of caring for and/or making up the lips. For example, it is known to formulate lip gloss using oils such as hydrogenated polyisobutene and other oils in combination with dextrin esters.
Although this type of product is favored by the consumers thanks to its excellent conditioning effect to the lips, it is still found not satisfying. Consumers found it sticky and thus uncomfortable on the lips after application.
The inventors found that by using oils with low viscosity may solve the issue, but lip glosses with low viscosity oils are too liquid, and consequently it impacts the quality of usage of the product. While applying on the lips, the layer of the composition spread was too thick, resulting in the leaking or bleeding of the composition outside the lip area.
Moreover, when colouring agents exist, the product may not be stable due to the low viscosity. Therefore, there is a need to formulate a composition with an improved non-sticky feeling when application on keratin materials, in particular the lips.
Meanwhile, there is a need to formulate such a composition as described above, with sufficient viscosity.
The sufficient viscosity as disclosed above enables an improved quality of usage, such as pay-off, and spreading.
Furthermore, it is necessary to formulate a composition with the above mentioned properties, and stable over time. In particular, when pigments exist, there is a need to formulate a composition as disclosed above with stability over time.
SUMMERY OF THE INVENTION
The inventors found it possible to solve the problems listed above, by formulating a composition comprising at least one specific ester oil, at least one pasty compound, at least one ester of dextrin and fatty acid, and at least one non-emulsifying organopolysiloxane elastomer.
Specifically, the current invention relates to an anhydrous composition comprising:
a).at least one oil selected from ester containing at least 18 carbon atoms;
b).at least one pasty compound;
c).at least one ester of dextrin and fatty acid; and
d).at least one non-emulsifying organopolysiloxane elastomer.
For the purposes of the invention, the term "anhydrous composition" means a composition containing less than 2%and preferably less than 0.5%by weight of water relative to the total weight of the composition. Where appropriate, such small amounts of water may be provided by ingredients of the composition that contain it in residual amount, but are not deliberately provided.
Preferably, the “keratin material” according to the present invention is the skin and the lips. By “skin” , we intend to mean all the body skin, including the scalp. Still preferably, the keratin material is the lips.
The viscosity of a composition of the invention may be measured via any process known to those skilled in the art, and especially according to the following conventional process. Thus, the measurement can be carried out at 25℃ using a Rheomat 180 viscometer equipped with a spindle rotating at 200 rpm. Those skilled in the art may select the spindle for measuring the  viscosity from the spindles M1, M2, M3 and M4 on the basis of their general knowledge, so as to be able to perform the measurement.
Thus the viscosity of the composition according to the invention is measured at 25℃, using a ProRheo R180 viscometer equipped with a spindle M3 rotating at 200 rpm from the company Prorheo.
Preferably, the viscosity of the composition of the present invention ranges from 35 UD to 80 UD (DeviationUnits) , using the above mentioned method.
According to the present application, "stable over time" means that the composition after two months of storage at 25 to 45℃, shows no change in appearance, colour, odour, or viscosity.

b) Pasty compound (s)
The composition of the present invention comprises at least one pasty compound.
The term “pasty compounds” within the meaning of the present invention is understood to mean a lipophilic fatty compound with a reversible solid/liquid change in state which exhibits, in the solid state, an anisotropic crystalline arrangement and which comprises, at a temperature of 23℃, a liquid fraction and a solid fraction.
In other words, the starting melting point of the pasty fatty substance can be less than 23℃. The liquid fraction of the pasty compounds, measured at 23℃, can represent from 9 to 97%by weight of the pasty compounds. At 23℃, this liquid fraction preferably represents between 15 and 85%by weight, more preferably between 40 and 85%by weight.
Within the meaning of the invention, the melting point corresponds to the temperature of the most endothermic peak observed by thermal analysis (DSC) as described in Standard ISO 11357-3: 1999. The melting point of a pasty compounds can be measured using a  differential scanning calorimeter (DSC) , for example the calorimeter sold under the name “MDSC 2920” by TA Instruments.
The measurement protocol is as follows:
A 5 mg sample of pasty compounds placed in a crucible is subjected to a first rise in temperature ranging from -20℃ to 100℃ at a heating rate of 10℃/minute, is then cooled from 100℃ to -20℃ at a cooling rate of 10℃/minute and, finally, is subjected to a second rise in temperature ranging from -20℃ to 100℃ at a heating rate of 5℃/minute. During the second rise in temperature, the variation in the difference in power absorbed by the empty crucible and by the crucible comprising the sample of pasty compounds is measured as a function of the temperature. The melting point of the pasty compounds is the value of the temperature corresponding to the tip of the peak of the curve representing the variation in the difference in power absorbed as a function of the temperature.
The liquid fraction by weight of the pasty compounds at 23℃ is equal to the ratio of the enthalpy of fusion consumed at 23℃ to the enthalpy of fusion of the pasty fatty substance.
The enthalpy of fusion of the pasty fatty substance is the enthalpy consumed by the latter to change from the solid state to the liquid state. The pasty fatty substance is “in the solid state” when the whole of its mass is in the solid crystalline form. The pasty compounds is “in the liquid state” when the whole of its mass is in the liquid form.
The enthalpy of fusion of the pasty compounds is equal to the area under the curve of the thermogram obtained using a differential scanning calorimeter (DSC) , such as the calorimeter sold under the name MDSC 2920 by TA Instruments, with a rise in temperature of 5 or 10℃ per minute, according to Standard ISO 11357-3: 1999.
The enthalpy of fusion of the pasty compounds is the amount of energy necessary to change the pasty compounds from the solid state to the liquid state. It is expressed in J/g.
The enthalpy of fusion consumed at 23℃ is the amount of energy absorbed by the sample to change from the solid state to the state which it exhibits at 23℃, composed of a liquid fraction and of a solid fraction.
The liquid fraction of the pasty compounds measured at 32℃ preferably represents from 30 to 100%by weight of the pasty compounds, preferably from 50 to 100%by weight of the pasty compounds, more preferably from 60 to 100%by weight of the pasty compounds. When the liquid fraction of the pasty compounds measured at 32℃ is equal to 100%, the temperature of the end of the melting range of the pasty compounds is less than or equal to 32℃.
The liquid fraction of the pasty compounds measured at 32℃ is equal to the ratio of the enthalpy of fusion consumed at 32℃ to the enthalpy of fusion of the pasty compounds. The enthalpy of fusion consumed at 32℃ is calculated in the same way as the enthalpy of fusion consumed at 23℃.

For the purposes of the present invention, the term “apolar oil” means an oil whose solubility parameter at 25℃, δa, is equal to 0 (J/cm31/2.
The definition and calculation of the solubility parameters in the Hansen three-dimensional solubility space are described in the article by C. M. Hansen: "The three dimensional solubility parameters"  , J. Paint Technol. 39, 105 (1967) .
According to this Hansen space:
-δD characterizes the London dispersion forces derived from the formation of dipoles induced during molecular impacts;
-δp characterizes the Debye interaction forces between permanent dipoles and also the Keesom interaction forces between induced dipoles and permanent dipoles;
-δh characterizes the specific interaction forces (such as hydrogen bonding, acid/base, donor/acceptor, etc. ) ; and
-δa is determined by the equation: δa = (δp2 + δh21/2.

EXAMPLES
Formulation examples
The following invention and comparative formulas were prepared:
Figure PCTCN2016072303-appb-000012
Figure PCTCN2016072303-appb-000013
Comparative formula 1’ corresponds to invention formula 1, contains a silicone dimethicone crosspolymer which is known for reducing sticky feeling.
Comparative formula 2’ corresponds to invention formula 2, which does not contain pasty compound as claimed in the present invention.
All the formulas were QS to 100 using diisostearyl malate.
The formulas were prepared following the steps:
mixing phase A under 25℃ until homogenous;
heating phase A to 85℃, and adding phase B into phase A, mixing until homogeneous;
cooling down the mixture to 25℃, adding phase C to the mixture and mixing until homogeneous. Evaluation examples
The evaluations of the non-stickiness, viscosity, stability, as well as quality of usage of the invention and comparative formulas were performed.
The non-stickiness was evaluated by both instrumental and panelists.
Instrumental test of the non-stickiness of the invention and comparative formulas were performed by simulating the movements of the lips containing the formulas.
Specifically, 20 mg of the invention formula 1 and comparative formula 1’ were applied using an applicator evenly on two pieces of bio skin with diameters of 5 cm sold by the company Beaulax, Co., Ltd. , respectively. They were putting together adjacent to each other, and immediately separated using the device Diastron MTT170, to test the traction force for separating the two bio skins.
The result was shown as the value of Peak_Load (N) , which is the maximum traction force between the two pieces of bio skins under a predetermined rate as points per second throughout the process. The pulling force was measured in newton (N) . Higher value of Peak_Load (N) represents more sticky feeling of the formula.
Then 6 panelists applied the invention and comparative formulas, respectively, as lip oil products, on their lips, and scores of stickiness were given by the panelists, respectively:
2.5 to 3 (included) : not sticky at all, very light and pleasant feeling after application;
1.5 to 2.5 (included) : not sticky to a little sticky, but acceptable after application;
below 1.5 (included) : sticky, uncomfortable after application.
The viscosities of the invention and comparative formulas were evaluated using a Rheomat 180 viscometer equipped with a spindle rotating at 200 rpm at 25℃. The spindle used in the test was spindle M3.
The invention formulas were then stored under temperatures between 25 to 45℃ for 2 months, in order to evaluate the stability.
The quality of usage of the invention and comparative formulas were evaluated by 6 panelists by using the formulas, respectively, as lip oil products on their lips, and comments were given by the panelists in terms of pay-off and spreading.
The results were as follow:
Figure PCTCN2016072303-appb-000014
Figure PCTCN2016072303-appb-000015
It is observed that, comparing to the comparative formula 1’ , invention formula 1, even though containing more diisostaryl malate, which is more viscous comparing to the dimethicone in the silicone elastomer, had reduced 7%of traction force, which is clearly perceived by the panelists after application. The comparative formula 1’ s hows a sticky feeling after application on the lips, which is not desired by the panelists.
Besides, comparing to the comparative formula 2’ , the invention formula 2 shows a better non-sticky feeling on the lips according to the panelists, and meanwhile maintains sufficient viscosity. On the other hand, the comparative formula 2’ s hows a poor quality of usage, due to the low viscosity.
In conclusion, the invention formulas 1 and 2 possess an improved non-stickiness, sufficient viscosities, as well as a good quality of usages, comparing to the comparative 1’ a nd 2’ .
Finally, it is observed that both invention formulas 1 and 2 are stable over time.
