Definitions
- thermotropic liquid crystal polymer structured by a thermotropic liquid crystal polymer
- the present invention relates to a composition for caring for and / or making up the skin and / or the lips of human beings, containing a liquid fatty phase comprising at least one anhydrous solvent, structured by a thermotropic liquid crystal polymer, in order to obtain media having substantially the consistency of a gel at room temperature and that of a fluid when applied to the skin or lips of humans.
- liquid fatty phase in the sense of the demand, is meant a fatty phase liquid at ambient temperature (approximately 25 ° C.), composed of one or more fatty substances liquid at ambient temperature, also called oils, compatible with each other.
- structured fatty phase is understood in the sense of the request, an fatty phase which has the consistency of a gel at room temperature.
- Liquid crystal polymers also called LCP for Liquid Crystals Polymers, are polymers with a start of organization in the molten state, which results in mesophases, or mesomorphic phases, or "liquid crystal” phases.
- Liquid crystal polymers are grafted with rigid molecules, having a marked, elongated or flat anisotropic shape, such as that of a rod or a disc, at the origin of the appearance of the mesomorphic phases.
- thermotropic liquid crystal polymer By thermotropic liquid crystal polymer (LCP) is meant a liquid crystal polymer for which the transition between the solid state and the liquid state is crossed by heating before thermal degradation.
- the mesomorphic phases are present in a range of temperatures having for low limit the glass transition temperature T g of thermotropic liquid crystal polymers, and for high limit their clarification temperature T C
- is the temperature from which the total disruption of the orientation order occurs, the disruption of the short distance position order occurring at temperatures equal to or below the clarification temperature T C
- the clarification temperature T ci is also called the isotropization temperature.
- medium having substantially the consistency of a gel is understood to mean, in the sense of the request, a medium structured by a thermotropic liquid crystal polymer having a mesomorphic phase in at least two dimensions.
- Smectics are at least two-dimensional mesomorphic phases with layered structures. They have an orientation order and a short distance position order on at least one dimension.
- the molecules that make up these phases are represented in the form of rods, whose centers of gravity are located in equidistant and parallel planes, thus forming superimposed layers.
- the molecules have a preferential axis of orientation with respect to these layers.
- the term “medium having substantially the consistency of a fluid” is understood to mean, in the sense of the request, a medium structured by a thermotropic liquid crystal polymer having a mesomorphic phase with at most one dimension.
- Nematics are one-dimensional mesomorphic phases. They only have an orientation order. The molecules that make up these phases are represented in the form of rods randomly distributed and oriented along a privileged axis, also called the directing axis.
- Certain cosmetic solvents are difficult to structure, in particular to gel and / or stiffen, in particular anhydrous solvents such as hydrocarbon and silicone oils.
- solid ingredients in particular, are used for structuring the liquid fatty phase.
- mineral (silica) or organic (wax) particles which are concentrated until the desired texture is obtained.
- the application to the skin of such products leads to deposits which spread with difficulty and do not form a continuous film.
- these products constitute care and / or makeup products which transfer.
- the subject of the invention is therefore a cosmetic composition which makes it possible to overcome these drawbacks.
- the subject of the invention is a cosmetic composition comprising a liquid fatty phase containing at least one anhydrous solvent, structured by a thermotropic liquid crystal polymer, comprising a main macromolecular chain and thermotropic mesogenic groups grafted into side chains on the chain macromolecular.
- liquid crystal polymers provide physical crosslinking of the cosmetic composition, the degree of which varies depending on the temperature. They lead to a modulation as a function of the temperature of the rheological properties of the film deposited, in particular on the skin and / or the lips of human beings.
- thermotropic liquid crystal polymers comprising thermotropic mesogenic groups grafted into side chains on the main macromolecular chain are thermotropic LCPs with side chains, also called SCLCP or "Side Chain LCP".
- SCLCPs are used for their antimicrobial action in the Japanese patent JP-5017396, or for their action promoting dental hygiene in the international patent application WO-9745095 and the American patent US-508927.
- the optical properties of insoluble LCPs relate to international patent applications WO-9508786 and WO-09422976, as well as in English patent GB-2282146.
- the documents of the prior art more specifically mentioning the mechanical properties of LCPs only relate to LCP polymers with main chain having a high glass transition temperature such as polyaramides of the Kevlar® type and intervening mainly in materials or matrices to strengthen their mechanical properties, which is not the subject of the invention.

- S B the B smectics
- Smectics B have an order of orientation and a double order of position at short distance, because the molecules are not randomly distributed in the layers, but form a hexagonal mesh.

- the term “grafting rate” is understood to mean, within the meaning of the request, the percentage of monomeric units of the macromolecular chain grafted with a mesogenic group. For example, a grafting rate of 25% means that one out of four monomeric units is grafted by a mesogenic group, and a grafting rate of 60% means that three out of five monomeric units are grafted through mesogenic groups.
- the grafting rate of the thermotropic mesogenic groups on the macromolecular chain is from 10% to 70%, preferably 15% to 65%, and better still from 25 to 60%.

- Y is a polar or apolar end group such as an alkyl, (methyl, ethyl, propyl), alkoxy (methoxy, ethoxy, propoxy), -CN or - O2 group.
- the rigidity of the mesogenic group is ensured by the aromatic cycles connected by the element X.
- the element Y is a terminal grouping which favors the smectic phases if it is polar and the nematic phases if it is little or not at all polar.
- the polarity of the Y element also affects the thickness of the smectic layers.
- the mesogenic groups are linked to the macromolecular chain via a spacer.
- the spacer is a short flexible block, preferably chosen from the oligomers of methylene, oxymethylene, oxyethylene, and dimethylsiloxane.
- the spacer has a minimum length, which generally corresponds to three monomer units.
