## Background
The present patent application relates to water-in-oil inverse latices, to a process for preparing them and to their use as thickeners and/or emulsifiers in industrial products, skincare and haircare products or for the manufacture of cosmetic, dermopharmaceutical or pharmaceutical preparations.
Inverse latices of the partially or totally salified acid 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propane-sulfonic acid (also known as 2-acrylamido-2-methyl-propanesulfonic acid, ATBS or AMPS) and also their cosmetic and/or pharmaceutical use have been the subject of many patent applications. However, the presence of large amounts of water and of oil represents an appreciable drawback in terms of volume, cost and occasionally increased risks and/or toxic effects.
Solutions have thus been developed to increase the concentration of polymers in the final latices, for example by subjecting the reaction medium, at the end of polymerization, to a vacuum distillation step in order to remove a more or less large amount of water and oil. However, this distillation is difficult to implement since it often induces destabilization of the inverse latex, which needs to be countered by the prior addition of stabilizers. European patent applications EP 0 161 038 and EP 0 126 528 and also British patent application GB 1 482 515 disclose such a use of stabilizing polymers.
The drawback of these products is that they contain alcohols or glycols that might induce environmental problems. Furthermore, the reaction medium occasionally sets to a solid during the distillation step, without this phenomenon having ever really been explained, but the definite consequence of which is destruction of the batch of inverse latex and tiresome and expensive cleaning of the reactor. Finally, even when the distillation proceeds correctly, the inverse latices obtained often invert with difficulty, have a high viscosity and occasionally contain microgels. These drawbacks thus prohibit their use in the manufacture of cosmetic formulations and/or in textile printing.
Accordingly, the Applicant set itself the aim of developing concentrated inverse latices, i.e. latices comprising at least 50% by weight of polymer and less than 5% by weight of water, which do not have such drawbacks and which have an improved content of electrolytes.
According to a first aspect, one subject of the invention is a composition in the form of an inverse latex comprising:

    
    
        a) from 50% by weight to 80% of at least one linear, branched or crosslinked organic polymer (P),
        b) from 5% by weight to 10% of an emulsifying system (S1) of water-in-oil (W/O) type,
        c) from 5% by weight to 45% by weight of at least one oil, and
        d) from 0% to 5% of water,

and characterized in that from 0.01% to 10% in molar proportions of the monomer units that said polymer P comprises is at least one neutral monomer of formula (I):

C(R1)(R3)═C(R2)—C(=0)-0-(CH2—CH2—O)n—R4  (I)

in which the radicals R1, R2 and R3, which may be identical or different, represent, independently of each other, a hydrogen atom or a linear or branched alkyl radical containing from 1 to 4 carbon atoms, the radical R4 represents a linear or branched, saturated or unsaturated aliphatic radical containing from 6 to 30 carbon atoms and n represents a number between 1 and 50.

    
    


The term “linear or branched alkyl radical containing from 1 to 4 carbon atoms” denotes for the radicals R1, R2 and R3 methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl or tert-butyl radicals.
The term “linear or branched, saturated or unsaturated aliphatic radical containing from 6 to 30 carbon atoms” denotes for the radical R4 saturated linear radicals more particularly such as, for example, hexyl, octyl, nonyl, decyl, undecyl, dodecyl, tetradecyl, hexadecyl, octadecyl, eicosyl, docosyl, tetracosyl, hexacosyl, octacosyl or triacontyl radicals.
A subject of the invention is more particularly a composition as defined in claim 1, in which from 0.05% to 5% in molar proportions and preferably from 0.1% to 1% in molar proportions of the monomer units that said polymer P comprises is at least one neutral monomer of formula (I).
The composition as defined above contains either a single polymer (P) or a mixture of different polymers (P).
According to a first particular aspect of the present invention, the polymer (P) is:

    
    
        either a copolymer in which each of the various monomers of the compound of formula (I) is chosen, independently of each other, either from those containing a partially or totally salified strong acid function or from those containing a partially or totally salified weak acid function or from neutral monomers, or from cationic monomers.
    
    


In the composition as defined above, the emulsifying system (S1) of water-in-oil (W/O) type consists either of a single surfactant or of a mixture of surfactants on condition that said mixture has an HLB value that is low enough to induce water-in-oil emulsions. Examples of emulsifiers of water-in-oil type include sorbitan esters, for instance sorbitan oleate, for instance the product sold by the company SEPPIC under the name MontaneTM 80, sorbitan isostearate, for instance the product sold by the company SEPPIC under the name MontaneTM 70 or sorbitan sesquioleate, for instance the product sold by the company SEPPIC under the name MontaneTM 83. Mention may also be made of certain polyethoxylated sorbitan esters, for example pentaethoxylated sorbitan monooleate, for instance the product sold by the company SEPPIC under the name MontanoxTM 81 or pentaethoxylated sorbitan isostearate, for instance the product sold under the name MontanoxTM 71 by the company SEPPIC. Mention may also be made of diethoxylated oleocetyl alcohol, for instance the product sold under the name SimulsolTM OC 72 by the company SEPPIC, polyesters with a molecular weight of between 1000 and 3000, products of condensation between a poly(isobutenyl)succinic acid or the anhydride thereof such as HypermerTM 2296 sold by the company Uniqema or, finally, block copolymers with a molecular weight of between 2500 and 3500, for instance HypermerTM B246 sold by the company Uniqema or SimalineTM IE 200 sold by the company SEPPIC.
The term “branched polymer” denotes, for (P), a nonlinear polymer containing pendent chains so as to obtain, when this polymer is dissolved in water, a high state of entanglement leading to very high low-gradient viscosities.
The term “crosslinked polymer” denotes, for (P), a nonlinear polymer having in water a water-insoluble but water-swellable three-dimensional network and thus leading to the production of a chemical gel.
The composition according to the invention may comprise linear polymers, crosslinked polymers and/or branched polymers.
When the polymer (P) is crosslinked, it is more particularly crosslinked with a diethylenic or polyethylenic compound in a molar proportion, expressed relative to the monomers used, of less than or equal to 0.25%, more particularly less than or equal to 0.05% and most particularly between 0.005% and 0.01%. Preferably, the crosslinking agent and/or the branching agent is chosen from ethylene glycol dimethacrylate, diethylene glycol diacrylate, sodium diallyloxyacetate, ethylene glycol diacrylate, diallyl urea, triallylamine, trimethylolpropane triacrylate and methylenebis(acrylamide), or a mixture of these compounds.

For the monomers with a strong acid function or with a weak acid function, the term “salified” indicates that they are alkali metal salts such as the sodium or potassium salts, salts of nitrogenous bases, for instance the ammonium salt, the lysine salt or the monoethanolamine (HO—CH2—CH2—NH4+) salt.
The various neutral monomers of the compound of formula (I) are especially chosen from acrylamide, methacrylamide, diacetoneacrylamide, dimethyl-acrylamide, N-isopropylacrylamide, N-[2-hydroxy-1,1-bis(hydroxymethyl)ethyl]propenamide [or tris(hydroxymethyl)acrylamidomethane or N-tris(hydroxymethyl)methylacrylamide, also known as THAM], (2-hydroxyethyl)acrylate, (2,3-dihydroxypropyl)acrylate, (2-hydroxyethyl)methacrylate, (2,3-dihydroxypropyl)methacrylate, an ethoxylated derivative with a molecular weight of between 400 and 1000, of each of these esters, or vinylpyrrolidone.
The cationic monomers are especially chosen from quaternary ammonium derivatives. Said monomers may be, for example, the salts of 2,N,N,N-tetramethyl-2-[(1-oxo-2-propenyl)amino]propanammonium, of 2,N,N-tri-methyl-2-[(1-oxo-2-propenyl)amino]propanammonium, of N,N,N-trimethyl-2-[(1-oxo-2-propenyl)oxy]ethanammonium, of N,N,N-trimethyl-3-[(1-oxo-2-propenyl)oxy]propan-ammonium, of N,N,N-trimethyl-2-[(1-oxo-2-propenyl)-amino]propanammonium or of diallyldimethylammonium. The term “salt” more particularly means the chlorides, bromides or iodides of said ammonium salts.

According to another particular aspect, in the composition as defined above, the monomer is chosen from the compounds of formula (I′):

CH2═CH—C(=0)-0-(CH2—CH2—O)n′—R′4  (I′)

corresponding to formula (I) in which the radicals R1, R2 and R3 each represent a hydrogen atom, the radical R4 represents an aliphatic radical chosen from octyl, decyl, dodecyl, tetradecyl, hexadecyl, octadecyl, eicosyl, docosyl and tetracosyl radicals, and n′ represents a number between 4 and 25; or alternatively the compounds of formula (I′′):

MarcolTM 52 is a commercial oil corresponding to the definition of liquid petroleum jellies of the French Codex. It is a white mineral oil in accordance with the FDA regulations CFR 172.878 and CFR 178.3620 (a) and is registered in the US Pharmacopea, US XXIII (1995) and in the European Pharmacopea (1993). The composition according to the invention may also contain various additives such as complexing agents, transfer agents or chain-limiting agents.

        b) the polymerization reaction is initiated by introduction into the emulsion formed in a) of a free-radical initiator, and the reaction is then left to proceed, and
        c) the reaction medium obtained from step b) is concentrated by distillation until said volatile oil has been completely removed.
    
    


The volatile oils that are suitable for use in the process as defined above are, for example, light isoparaffins containing from 8 to 11 carbon atoms, for instance those sold under the names IsoparTM G, IsoparTM L, IsoparTM H or IsoparTM J.
According to one preferred implementation of the process as defined above, the polymerization reaction is initiated with a redox couple, such as the cumene hydroperoxide-sodium metabisulfite couple, at a temperature of less than or equal to 10° C., and is then performed either quasi-adiabatically up to a temperature of greater than or equal to 40° C. and more particularly greater than or equal to 50° C., or by controlling the temperature change.
When step c) is complete, one or more emulsifiers of oil-in-water type are introduced, if desired, at a temperature below 50° C.
A subject of the invention is also the use of the composition as defined above for preparing a cosmetic, dermopharmaceutical or pharmaceutical topical composition.
A topical composition according to the invention, intended to be applied to human or animal skin or mucous membranes, may consist of a topical emulsion comprising at least one aqueous phase and at least one oil phase. This topical emulsion may be of the oil-in-water type. More particularly, this topical emulsion may consist of a fluid emulsion, such as a milk or a fluid gel. The oil phase of the topical emulsion may consist of a mixture of one or more oils.
A topical composition according to the invention may be intended for cosmetic use or may be used for preparing a medicament intended for treating skin and mucous membrane diseases. In the latter case, the topical composition then comprises an active principle that may consist, for example, of an anti-inflammatory agent, a muscle relaxant, an antifungal agent or an antibacterial agent.
When the topical composition is used as a cosmetic composition intended to be applied to the skin or mucous membranes, it may or may not comprise an active principle, for example a moisturizer, a tanning agent, a sunscreen, an anti-wrinkle agent, an agent for slimming purposes, a free-radical scavenger, an antiacne agent or an antifungal agent.
A topical composition according to the invention usually comprises between 0.1% and 10% by weight of the thickener defined above. The pH of the topical composition is preferably greater than or equal to 5.

According to yet another aspect, the invention relates to the use of the novel thickener in accordance with the invention, mentioned above, for thickening and emulsifying a topical composition comprising at least one aqueous phase.
The composition according to the invention is an advantageous substitute for those sold under the names SepigelTM T 305, SepigelTM 501, SepigelTM EG, SepigelTM NS or SepigelTM 600 by the Applicant, since it also has good compatibility with the other excipients used for the preparation of formulations such as milks, lotions, creams, soaps, baths, balms, shampoos or hair conditioners. It may also be used with said Sepigel or Simulgel products.
It is especially compatible with the concentrates described and claimed in international publications WO 92/06778, WO 95/04592, WO 95/13863, WO 96/37285, WO 98/22207 and WO 98/47610 and in patent FR 2 734 496, with the surfactants described in WO 93/08204.
It is particularly compatible with MontanovTM 68, MontanovTM 82, MontanovTM 202 or SepiperlTM N.

It may also be used to form aqueous gels at cosmetically or physiologically acceptable acidic pH, such as those described in WO 93/07856; it may also be used in combination with nonionic celluloses, to form, for example, styling gels such as those described in EP 0 684 024, or alternatively in combination with fatty acid esters of sugars, to form compositions for treating the hair or the skin such as those described in EP 0 603 019, or alternatively in shampoos or hair conditioners as described and claimed in WO 96/21316 or, finally, in combination with an anionic homopolymer such as CarbopolTM to form hair-treatment products such as those described in DE 195 23 596, or in combination with other thickening polymers.
The composition according to the invention is also compatible with active principles such as, for example, self-tanning agents, for instance dihydroxyacetone (DHA) or antiacne agents; it may thus be introduced into self-tanning compositions such as those claimed in EP 0 715 845, EP 0 604 249, EP 0 576 188 or in WO 93/07902.
It is also compatible with N-acylamino acid derivatives, which allows its use in calmative compositions, especially for sensitive skin, such as those described or claimed in WO 92/21318, WO 94/27561 or in WO 98/09611.
When the composition as defined above is intended for treating the hair, it more particularly comprises an inverse latex of cationic polymer that is a subject of the present invention.
When the composition as defined above is intended for treating the skin and/or mucous membranes, it more particularly comprises an inverse latex of anionic polymer that is a subject of the present invention.

EXAMPLE 3
Inverse Latex of the Copolymer AM/AA/(ALE-4OE) (Anionic Thickener—Composition 3)
The process is performed as in the preceding example, but in this case 6 g of tetraethoxylated lauryl acrylate are used and no methylenebisacrylamide is introduced.
After introduction of 2% of MontanoxTM 20 and 4% of Laureth-7, an anionic thickening inverse latex containing about 63% polymer is obtained. The product obtained is sparingly viscous, it has high thickening power and it inverts easily. Its water content measured by Karl-Fisher titrimetry is 2.3% by weight.
