Definitions
- the present invention relates to new block copolymers, to their use in the cosmetic field in particular, as well as to the compositions comprising them.
- polymers with antinomic properties are often sought: obtaining good fixation without tacky; good resistance of products to humidity with good elimination in shampoo; or a makeup composition combining comfort and hold. Furthermore, these polymers should preferably be transported in water, in soluble or dispersible form. This is the reason why the formulators have turned more particularly to copolymers, and in particular to block polymers or block polymers, which have advantageous mechanical properties. They can in particular allow these antithetical properties to be obtained, because they result from the association, within the same chain, of sequences of different properties: one which can provide rigidity and the other flexibility, for example . Thus, the styling properties of styling products or lacquers can be modulated.
- block copolymers which can be transported in water, mention may be made of those described in application O02 / 28358.
- block copolymers are described, a block of which is a copolymer mainly comprising nonionic hydrophilic units in admixture with hydrophobic units. These copolymers have a nonionic character. In order to make them soluble in water, the amount of hydrophilic unit is very high; this limitation does not allow access to a large range of structures.
- block polymers one block of which is a copolymer comprising acrylic acid units, and another block of which is non-ionic hydrophilic. These block polymers however exhibit a strong fluctuation in their properties as a function of humidity.
- block copolymers described in O02 / 28357 which are water-soluble, and in which all the blocks are formed from monomers non-ionic, but which also exhibit large fluctuations in their properties as a function of humidity.
- diblock or triblock copolymers which can give aqueous gelled compositions; these copolymers can in particular be of the poly (styrene / methacrylic acid) -b-poly (ethyl acrylate / methacrylic acid) type.
- these copolymers are thickeners which, in certain cases, can be considered as a drawback, in particular by making the formulation difficult. Indeed, obtaining gels is not always sought: this is the case for example for aerosols or nail varnishes, for which fluid solutions are necessary. It has therefore been found that the majority of block copolymers intended to be transported in water mainly comprise hydrophobic units and tend to form gels, which is a drawback.
- the object of the present invention is to provide block copolymers, or block polymers, which have advantageous mechanical properties, and which can be used in large quantities without appreciably influencing the thickening or gelling, therefore the viscosity, of the composition that contains them.
- the copolymers according to the invention do not form, in water, a viscoelastic gel, that is to say a gel having an elastic modulus (G ′) greater than the viscous modulus (G ′′). copolymers forming a film or a deposit are also sought, the removal of which with perfect shampooing.
- An object of the invention is therefore a linear, ethylenic, block copolymer comprising at least a first block and at least a second block, each block comprising at least one ionic hydrophilic unit, which may be different from a block to l 'other, said ionic hydrophilic unit being present in each sequence at a rate of 2 to 100% by weight relative to the weight of said sequence.
- Another object is a cosmetic or pharmaceutical composition comprising in a physiologically acceptable medium, in particular cosmetically or dermatologically acceptable, at least one copolymer as defined below.
- copolymers according to the invention have comfortable mechanical properties: they can be rigid while having a certain flexibility or elasticity, ensuring maintenance of the hair lasting over time. They can also have good adhesion without being sticky to the touch. They find a very particular application in the cosmetic field, in particular in hair or make-up. When used in nail polish, these polymers form a deposit that adheres well to the nail without easily wearing out.
- the block polymer (or block polymer) according to the invention is a linear block ethylenic polymer, advantageously film-forming.
- ethylenic polymer is meant a polymer obtained by polymerization of monomers comprising ethylenic unsaturation.
- block polymer is meant a polymer comprising at least 2 successive blocks distinct, that is to say of different chemical natures.
- the polymer according to the invention is a polymer with a linear structure.
- a polymer with a non-linear structure is, for example, a polymer with a branched, star, grafted, or other structure.
- all the monomers used to prepare a linear polymer are mono-functional, that is to say have only one polymerizable function.
- the polymerization orcers they can be monofunctional or difunctional.
- film-forming polymer is meant a polymer capable of forming on its own or in the presence of an auxiliary film-forming agent, a continuous and adherent film on a support, in particular on keratin materials.
- Each block, or block, of the polymer according to the invention is derived from one type of monomer or from several different types of monomer. This means that each block can consist of a homopoly era or a copolymer; this copolymer constituting the sequence which may in turn be statistical or alternating or with a gradient; the distribution of the monomers within each sequence can therefore be random or controlled depending on the nature and / or the reactivity of the monomers and / or the preparation process used.
- the block polymer according to the invention therefore comprises at least two blocks, advantageously two blocks (diblock) or three blocks (triblock), each of the blocks comprising at least one ionic hydrophilic monomer, present in each block in an amount of at least 2%. by weight relative to the weight of the sequence.
- said hydrophilic ionic monomer may in fact be a mixture of different hydrophilic ionic monomers.
- the ionic hydrophilic monomer (s) may be identical, totally or partially, or different, from one sequence to another.
- the ionic hydrophilic monomers are present in each block in an amount of 2 to 100% by weight, relative to the weight of the block, in particular from 3 to 70% by weight, even better from 5 to 50% by weight, or even from 8 to 30% by weight.
- a monomer is said to be hydrophilic if the corresponding homopolymer is hydrophilic, that is to say if it is water-soluble or water-dispersible.
- the omopolymer is water-soluble if it is soluble in water, at a rate of at least 5% by weight, at 25 ° C.
- the omopolymer is water dispersible if it forms in water, at a concentration of 5% by weight, at 25 ° C, a stable suspension or dispersion of fines. particles, generally spherical.
- the average size of the particles constituting said dispersion is less than 1 ⁇ m and, more generally, varies between 5 and 400 nm, preferably from 10 to 250 nm. These particle sizes are measured by light scattering (with a Coulter Counter type device).
- the hydrophilicity of a monomer can also be defined by the value of the logarithm of the apparent partition coefficient octanol-1 / water, also called log P; a monomer can be considered to be hydrophilic when this value is less than or equal to 2, for example between -8 and 2, preferably less than or equal to 1.5, in particular less than or equal to 1, and in particular between -7 and 1, or even between -6 and 0.
- log P values are known and are determined according to a standard test which determines the concentration of the monomer in octanol and water.
- the values can in particular be calculated using the ACD software (Advanced Chemistry Development) Software solaris V4.67; they can also be obtained from Exploring QSAR: hydrophobic, electronic and steric constants (ACS professional reference book, 1995). There is still a website which provides estimated values (address: http: //esc.syrres .com / interkow / kowdemo.htm).
- the final polymer comprises in each of its sequences at least one hydrophilic monomer present at least 2% by weight relative to the weight of the block.
- hydrophilic monomers it is possible to hydrolyze the polymer when it comprises units of the (meth) acrylic ester type, capable of being hydrolyzed to give units having a carboxylic acid function; this may be the case when the polymer comprises units of the (meth) acrylate type of methyl, ethyl, hydroxyethyl, tert-butyl, benzyl, trimethoxysilyl or ethyltrimeth ⁇ xysilyl.
- Hydrolysis can thus be carried out once the polymer has been synthesized, under acidic conditions (for example in the presence of sulfuric acid, hydrochloric acid or trifluoroacetic acid) or basic conditions (for example in the presence of hydroxides of alkaline earth metals such as soda or potash, alkali metal alcoholates such as potassium t-butoxide, or amines such as ammonia).
- acidic conditions for example in the presence of sulfuric acid, hydrochloric acid or trifluoroacetic acid
- basic conditions for example in the presence of hydroxides of alkaline earth metals such as soda or potash, alkali metal alcoholates such as potassium t-butoxide, or amines such as ammonia.
- the hydrolysis generally takes place between 5 and 100 ° C, preferably between 15 and 80 ° C.
- the hydrolyzed polymer can then be purified by repeated precipitation.
- the ionic hydrophilic monomers present in the final polymer can be chosen from anionic, cationic and / or amphoteric hydrophilic monomers.

- at least one block can comprise both at least one cationic hydrophilic monomer and at least one anionic hydrophilic monomer.

- the block copolymers according to the invention can be obtained by living or pseudo-living radical polymerization known as still controlled, described in particular in "New Method of Polymer Synthesis", Blackie Académie & Professional, Kunststoff, 1995, volume 2, page 1.
- Controlled radical polymerization designates polymerizations for which the secondary reactions which usually lead to the disappearance of the propagating species (termination reaction or transfer) are made very unlikely compared to the propagation reaction thanks to a free radical control agent.
- the imperfection of this mode of polymerization lies in the fact that when the concentrations of free radicals become high relative to the concentration of monomer, the secondary reactions become decisive again and tend to widen the distribution of the masses
- the polymerization living or pseudo-living is a polymerization for which the growth of polymer chains ceases only with the disappearance of the monomer.
- the number average mass (Mn) increases with the conversion.
- Such polymerizations lead to copolymers whose mass dispersity is low, that is to say to polymers with a polydispersity index by mass (Ip) generally less than 2.
- Anionic polymerization is a typical example of living polymerization.
- Pseudo-living polymerization is, in turn, associated with controlled radical polymerization.
- - radical polymerization controlled by nitroxides mention may be made of: - radical polymerization controlled by nitroxides.
- We can in particular refer to patent applications O96 / 24620 and WO00 / 71501 which describe the tools of this polymerization and their implementation, as well as the articles published by Fischer (Chemical Reviews, 2001, 101, 3581), by Tordo and Gnanou (J. Am. Che.
- the polymer chains of the copolymers grow simultaneously and therefore incorporate at all times the same ratio of co-monomers. All the chains therefore have the same or similar structures, hence a low dispersity in composition. These chains also have a low mass polydispersity index.
- the polymerization can be carried out according to the atom transfer technique (Atom Transfer Radical Polymerization or "ATRP", in English), or by reaction with a nitroxide, or even according to the technique of "reversible addition- fragmentation chain transfer "(" RAFT ”) or finally by the reverse “ATRP” technique, called “reverse ATRP”.
- the radical polymerization technique by atom transfer consists in blocking the growing radical species in the form of a C-halide bond (in the presence of a metal / ligand complex). This type of polymerization results in a control of the mass of the polymers formed and in a low mass dispersity index.
- radical polymerization by transfer of atoms is carried out by polymerization of one or more polymerizable monomers by the radical route, in the presence of: - an initiator having at least one transferable halogen atom; - a halogen compound comprising a transition metal capable of participating in a reduction step with the initiator and a “dormant” polymer chain, this will be called “chain transfer agent”; and - a ligand which can be chosen from compounds comprising a nitrogen (N), oxygen (0), phosphorus (P) or sulfur (S) atom, capable of being coordinated by a ⁇ bond to said compound comprising a transition metal, the formation of direct bonds between said compound comprising a transition metal and the polymer being formed being avoided.
- an initiator having at least one transferable halogen atom
- - a halogen compound comprising a transition metal capable of participating in a reduction step with the initiator and a “dormant” polymer chain, this will be called “chain transfer agent”
- the halogen atom is preferably a chlorine or bromine atom. This process is in particular described in application WO 97/18247 and in the article by Matyjasezwski et al. published in JACS, 117, page 5614 (1995).
- the radical polymerization technique by reaction with a nitroxide consists in blocking the growing radical species in the form of a bond of the C-0-NR a R type where R a and Rb can be, independently of one another, a alkyl radical having from 2 to 30 carbon atoms or forming one and the other, with the nitrogen atom, a ring having from 4 to 20 carbon atoms, such as for example a ring 2, 2, 6, 6-tetramethylpiperidinyl.

- the polymerization generally takes place in several stages according to the following general scheme: - a) in a first stage, the first monomer or mixture of monomers is polymerized to form a macroinitiator or precursor; - b) the polymers can be purified by precipitation and then dried under vacuum, - c) in a second step, the polymerization of the second block consisting of a monomer or a mixture of monomers is carried out at the end of the macroinitiator.
- Steps b and c are repeated as many times as necessary according to the number of sequences, which is the case for the production of diblock polymers of type AB, triblocks of type ABC or multiblocks (AB) ⁇ or (ABC) n with A , B and C of different chemical natures.
- a difunctional initiator is generally used to produce symmetrical triblock polymers of ABA or BAB type.
- the chain transfer agents and solvents may be the same or different in step a) and step b).
- the block or block polymers according to the invention can also be obtained using the conventional radical polymerization technique by carrying out the casting of the monomers in a sequenced manner. In this case, only control of the nature of the sequences is possible (no control of the masses). This involves first polymerizing an Ml monomer in a polymerization reactor; to follow, by kinetics for example, its consumption over time and then when Ml is consumed at around 95%, then to introduce a new monomer M2 into the polymerization reactor. A block structure polymer of the M1-M2 type is thus easily obtained.
