Definitions

  • the subject of the present invention is the use in an aqueous formula of an oil comprising one or more hydrophilic groups but no cationic group, as an aid to the deposition of an oil not comprising an ionizable group in a pH range from 2 with 12 ni of neutral hydrophilic group.

UTILISATION D UNE HUILE COMPRENANT UN GROUPEMENT USE OF AN OIL COMPRISING A GROUPING
HYDROPHILE COMME AIDE AU DEPOT D'UNE HUILE NON IONISABLEHYDROPHILIC AS AID FOR THE DEPOSITION OF NON-IONIZABLE OIL
EXEMPTE DE GROUPEMENT HYDROPHILEFREE FROM HYDROPHILIC GROUPING
La présente invention a pour objet l'utilisation dans une formule aqueuse d'une huile comprenant un ou plusieurs groupements hydrophiles mais aucun groupement cationique, comme aide au dépôt d'une huile ne comprenant pas de groupement ionisable dans une gamme de pH allant de 2 à 12 ni de groupement hydrophile neutre. Dans de nombreux domaines, qu'ils concernent le traitement de la peau et/ou du cheveu, ou encore le traitement des textiles, la fabrication du papier, il est bien souvent recherché de déposer une substance sur une surface, de manière à en modifier l'état.The subject of the present invention is the use in an aqueous formula of an oil comprising one or more hydrophilic groups but no cationic group, as an aid to the deposition of an oil not comprising an ionizable group in a pH range from 2 with 12 ni of neutral hydrophilic group. In many fields, whether they concern the treatment of the skin and / or the hair, or even the treatment of textiles, the manufacture of paper, it is very often sought to deposit a substance on a surface, so as to modify it. the state.
Ainsi, dans le domaine particulier de la cosmétique on peut chercher à déposer un composé hydrophobe, comme une huile par exemple, sur le cheveu de manière à en protéger la surface ou à en soigner les parties abîmées. La difficulté rencontrée est liée au fait que le dépôt n'est pas suffisant, et dans ce cas, d'autant plus marqué que la surface concernée est abîmée (traitement chimique type décoloration ou mécanique).Thus, in the particular field of cosmetics, it is possible to seek to deposit a hydrophobic compound, such as an oil for example, on the hair so as to protect the surface or to care for the damaged parts. The difficulty encountered is linked to the fact that the deposit is not sufficient, and in this case, all the more marked when the surface concerned is damaged (chemical treatment of discoloration or mechanical type).
Dans la demande internationale WO 99/29286, on a proposé de mettre en œuvre des huiles silicones aminées combinées avec des huiles silicones hydroxylées, de manière à augmenter le dépôt sur le cheveu abîmé. L'utilisation de ces silicones aminées est cependant particulièrement coûteux et peut être inefficace dans certaines formulations.In international application WO 99/29286, it has been proposed to use amino silicone oils combined with hydroxylated silicone oils, so as to increase the deposition on damaged hair. The use of these amino silicones is however particularly expensive and can be ineffective in certain formulations.
La présente invention a pour objet l'utilisation d'une dispersion comprenant une huile non ionisable dépourvue de groupements hydrophiles, combinée à un composé qui aide au dépôt de ladite huile sur différentes surfaces.The present invention relates to the use of a dispersion comprising a non-ionizable oil devoid of hydrophilic groups, combined with a compound which helps the deposition of said oil on different surfaces.
En outre, la présente invention permet d'augmenter les quantités d'huile déposée, que ce soit sur les surfaces plutôt hydrophiles que sur les surfaces hydrophobes.In addition, the present invention makes it possible to increase the amounts of oil deposited, whether on rather hydrophilic surfaces than on hydrophobic surfaces.
Ces buts et d'autres sont atteints par la présente invention qui a donc pour objet l'utilisation dans une formulation aqueuse, d'une huile (A) définie comme : (i) comprenant au moins un groupement hydrophile choisi parmi les fonctions hydroxyle, éther, amide, ester, carboxylique, phosphorique, phosphonique, sulfurique, sulfonique, sulfosuccinique, ou les sels correspondants ; (ii) et ne comprenant pas de groupement cationique à un pH compris entre 2 et 13 ; comme aide au dépôt sur une surface, d'une dispersion d'une huile (B) définie comme non ionisable à un pH compris entre 2 et 12 et ne comprenant aucun des groupements hydrophiles (i) précités. Elle a de même pour objet l'utilisation de la dispersion dans des formulations destinées à la cosmétique, la détergence, le traitement des textiles ou du papier, les revêtements peinture.These aims and others are achieved by the present invention which therefore relates to the use in an aqueous formulation, of an oil (A) defined as: (i) comprising at least one hydrophilic group chosen from hydroxyl functions, ether, amide, ester, carboxylic, phosphoric, phosphonic, sulfuric, sulfonic, sulfosuccinic, or the corresponding salts; (ii) and not comprising a cationic group at a pH of between 2 and 13; as an aid to the deposition on a surface, of a dispersion of an oil (B) defined as non-ionizable at a pH between 2 and 12 and not comprising any of the hydrophilic groups (i) mentioned above. It also relates to the use of the dispersion in formulations intended for cosmetics, detergency, treatment of textiles or paper, paint coatings.
Elle a de même pour objet une composition comprenant une dispersion de type huile 1 / eau, ou de type eau / huile 1 / eau, ou huile 2 / huile 1 / eau, dans laquelle la phase huile 1 comprend un mélange des huiles (A) et (B) sous forme d'une co- dispersion ; l'huile (A) étant définie comme comprenant (i) au moins un groupement hydrophile choisi parmi les fonctions hydroxyle, éther, amide, ester, carboxylique, phosphorique, phosphonique, sulfurique, sulfonique, sulfosuccinique, ou les sels correspondants et (ii) ne comprenant pas de groupement cationique à un pH compris entre 2 et 13 ; l'huile (B) étant définie comme non ionisable à un pH compris entre 2 et 12 et ne comprenant aucun des groupements hydrophiles (i) précités.It also relates to a composition comprising a dispersion of oil 1 / water type, or of water / oil 1 / water type, or oil 2 / oil 1 / water, in which the oil phase 1 comprises a mixture of oils (A ) and (B) in the form of a co-dispersion; the oil (A) being defined as comprising (i) at least one hydrophilic group chosen from the hydroxyl, ether, amide, ester, carboxylic, phosphoric, phosphonic, sulfuric, sulfonic, sulfosuccinic functions, or the corresponding salts and (ii) not comprising a cationic group at a pH of between 2 and 13; the oil (B) being defined as non-ionizable at a pH between 2 and 12 and not comprising any of the above-mentioned hydrophilic groups (i).
Mais d'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description qui va suivre. Ainsi que cela a été indiqué auparavant, l'invention a pour objet l'utilisation d'une dispersion d'une huile (A) comprenant (i) au moins un groupement hydrophile choisi parmi les fonctions hydroxyle, éther, amide, ester, carboxylique, phosphorique, phosphonique, sulfurique, sulfonique, sulfosuccinique, ou les sels correspondants ; et ne comprenant pas (ii) de groupement cationique à un pH compris entre 2 et 13 ; en tant qu'aide au dépôt sur une surface, d'une dispersion d'une huile (B) définie comme non ionisable à un pH compris entre 2 et 12 et ne comprenant aucun des groupements hydrophiles (i) précités.However, other characteristics and advantages of the present invention will appear more clearly on reading the description which follows. As indicated above, the subject of the invention is the use of an oil dispersion (A) comprising (i) at least one hydrophilic group chosen from the hydroxyl, ether, amide, ester and carboxylic functions , phosphoric, phosphonic, sulfuric, sulfonic, sulfosuccinic, or the corresponding salts; and not comprising (ii) cationic group at a pH between 2 and 13; as an aid to the deposition on a surface, of a dispersion of an oil (B) defined as non-ionizable at a pH between 2 and 12 and not comprising any of the hydrophilic groups (i) mentioned above.
Au sens de la présente invention, le terme dispersion couvre le cas où la phase dispersée se trouve sous forme solide (ou pâteuse) ou sous forme liquide. De plus, on utilisera indifféremment le terme huile pour désigner des composés se présentant sous une forme liquide, pâteuse ou solide à température ambiante. De préférence, l'huile (B) mise en œuvre se trouve sous une forme liquide à température ambiante (20-30°C).Within the meaning of the present invention, the term dispersion covers the case where the dispersed phase is in solid (or pasty) form or in liquid form. In addition, the term oil will be used interchangeably to denote compounds which are in a liquid, pasty or solid form at room temperature. Preferably, the oil (B) used is in a liquid form at room temperature (20-30 ° C).
De préférence la dispersion selon l'invention est telle que la phase continue est aqueuse.Preferably the dispersion according to the invention is such that the continuous phase is aqueous.
Dans le cas d'une émulsion d'huile (B), celle-ci peut être sous la forme d'une émulsion directe (huile dans eau), mais aussi sous la forme d'une émulsion multiple. Cette émulsion multiple peut être de diverses natures. Ainsi, les gouttelettes d'huile (B) peuvent, selon une possibilité, comprendre une phase aqueuse dispersée au sein même des gouttelettes d'huile (eau-dans huile-dans eau). Selon une autre possibilité, les gouttelettes d'huile (B) peuvent être dispersées au sein de gouttelettes d'une autre huile (huile-dans huile-dans eau). La dispersion d'huile (B) peut de même se trouver sous la forme d'une dispersion de particules solides d'huile. C'est notamment le cas avec les huiles dont le point de fusion est supérieur à la température ambiante (20- 30°C). Les cires en sont un exemple.In the case of an oil emulsion (B), this can be in the form of a direct emulsion (oil in water), but also in the form of a multiple emulsion. This multiple emulsion can be of various natures. Thus, the oil droplets (B) can, depending on one possibility, comprise an aqueous phase dispersed within the oil droplets (water-in oil-in water). Alternatively, the oil droplets (B) can be dispersed within droplets of another oil (oil-in oil-in water). The oil dispersion (B) can likewise be in the form of a dispersion of solid oil particles. This is particularly the case with oils whose melting point is higher than room temperature (20-30 ° C). Waxes are an example.
Par ailleurs, la taille moyenne des particules (liquides ou solides) de la dispersion d'huile (B) est plus particulièrement inférieure ou égale à 60 μm, notamment inférieure ou égale à 30 μm, et de préférence inférieure ou égale à 2 μm.

Plus particulièrement, selon cette éventualité, la taille moyenne des particules de la dispersion est comprise entre 10 nm et 0,15 μm (taille moyenne en nombre).The dispersion can therefore be in the form of a micro-dispersion or micro-emulsion. More particularly, according to this possibility, the average size of the particles of the dispersion is between 10 nm and 0.15 μm (average size in number).
Il est précisé que les dispersions selon l'invention sont stables en ce sens que la taille moyenne des particules de la dispersion, notamment les gouttelettes, est conservée à ± 20 % près, au bout d'une semaine, plus particulièrement au bout d'un mois, avantageusement au bout d'un an, à 25°C.It is specified that the dispersions according to the invention are stable in the sense that the average size of the particles of the dispersion, in particular the droplets, is kept to within ± 20%, after one week, more particularly after one month, advantageously after one year, at 25 ° C.
