Abstract
A cosmetic or dermatological composition, with a liquid crystal phase, comprises: (i) one or more alkylpolysaccharides; (ii) one or more alcohols with a carbon chain having from 12 to 22 carbon atoms; (iii) at least one ester with a melting point less than or equal to 30℃; and (iv) at least one hydrophilic UV filter. The preparation of the composition and the method using the composition are also disclosed.
Description
The present invention relates to a composition, in particular a cosmetic or dermatological composition, with a liquid crystal phase.
More particularly, said composition is a controlled release composition.
Lamella structure compositions are conventionally used in cosmetic field for providing a controlled release effect to the skin. For example, sunscreen formula’s ability to protect the skin from UV damage depends on a wide variety of factors, among which lamella structure formulations are introduced, see in Gao et al. Sunscreen Formulas with Multilayer Lamella Structure, Cosmetics &Toiletries magazine, Vol. 118, No. 10, 2003, p41-48. These publications relates to the use of liquid crystal system as a controlled release system.
On the other hand, skin sensory of a cosmetic product after application has always been one of the key factors to the consumers. Due to its nature, consumers find sunscreen products are often unpleasant to apply on the skin, especially when the temperature is relatively high, such as during summer time. There is thus a need for a composition, in particular a sunscreen composition with a pleasant sensory after application, such as a fresh and cooling sensation.
However none of the above mentioned document of the prior art has disclosed such a composition with a desired cooling and fresh sensory.
Besides, such liquid crystal system as a controlled release system needs to be improved notably with respect to their stability over time.
Also, such liquid crystal system as a controlled release system needs to be improved notably with respect to their instant and long-lasting cooling sensation after application.
AIMS OF THE INVENTION
Accordingly, one aim of the present invention is to provide a composition, in particular a cosmetic or dermatological composition, and in particular a liquid crystal system as a controlled release system, having a good stability over time.
Another aim of the present invention is to provide a composition, in particular a cosmetic or dermatological composition, and in particular a liquid crystal system as a controlled release system, having an instant and long-lasting cooling effect on a keratin material, especially on skin.
In particular, one aim of the present invention is to provide a composition, in particular a cosmetic or dermatological composition, and in particular a liquid crystal system as a controlled release system, having an instant and long-lasting cooling effect on a keratin material, especially on skin.
Another aim of the present invention is to provide a composition, in particular a cosmetic or dermatological composition, and in particular a liquid crystal system as a controlled release system, having together an instant and long-lasting effect on a keratin material, especially an instant and long-lasting cooling effect, and a good stability over time.

More particularly, said composition is a controlled release composition.
The invention relates to a cosmetic article comprising at least one composition as defined in the present invention.
The invention relates to a cosmetic process process for caring and/or making up a keratin material, comprising the application, to the surface of said keratin material, of at least one composition as defined in the present invention, wherein said keratin material is preferably skin, in particular face

Long-chain alcohols may also be used, for instance ether alcohols or Guerbet alcohols. Finally, use may also be made of certain more or less long fractions of alcohols of natural origin, for instance coconut or tallow oil.
Such alcohols are typically referred to as fatty alcohols.

In one embodiment, said ester with a melting point of less than or equal to 30℃ is selected from the group consisting of monoesters of C4 -C10 aliphatic acids and of C16 -C18 aliphatic alcohols, and any mixtures thereof.
The monoester (s) of C4 -C10 aliphatic acids and of C16 -C18 aliphatic alcohols which may be employed according to the invention are preferably selected from the group consisting of monoesters of C4 -C10 linear or branched saturated aliphatic acids and of C16 -C18 linear saturated aliphatic alcohols.
Monoesters of this type which are more particularly preferred according to the present invention are the ester of heptanoic acid and of stearyl alcohol (or stearyl heptanoate) , the ester of octanoic acid and of stearyl alcohol (or stearyl octanoate) or
stearyl heptanoate/octanoate mixtures, in particular the stearyl heptanoate/octanoate mixture such as for example the stearyl heptanoate (70%) /octanoate (30%) mixture sold, for example, by the company Croda under the trade name Crodamol W or by the company Stearineries Dubois under the trade name Dub Solide.
Within the meaning of the invention, the melting point corresponds to the temperature of the most endothermic peak observed in thermal analysis (DSC) as described in Standard ISO 1 1357-3; 1999. The melting point of the ester may be measured using a differential scanning calorimeter (DSC) , for example the calorimeter sold under the name MDSC by the company TA Instruments.
The measurement protocol is as follows: A sample of 5 mg of ester placed in a crucible is subjected to a first temperature rise ranging from -20℃ to 100℃, at a heating rate of 10℃/minute, it is then cooled from 100℃ to -20℃ at a cooling rate of 10℃/minute and it is finally subjected to a second temperature rise ranging from -20℃ to 100℃ at a heating rate of 5℃/minute. During the second temperature rise, the variation in the difference in power absorbed by the empty crucible and by the crucible containing the sample of ester is measured as a function of the temperature. The melting point of the compound is the temperature value corresponding to the top of the peak of the curve representing the variation in the difference in power absorbed as a function of the temperature.
