Abstract
Description
L'invention concerne un produit cosmétique comprenant au moins un flacon en polyoléfine et une composition cosmétique contenue dans le flacon.The invention relates to a cosmetic product comprising at least less a polyolefin bottle and a cosmetic composition contained in the bottle.
Le mascara est communément commercialisé dans des flacons de section transversale circulaire, carrée ou complexe, permettant son stockage et son application.Mascara is commonly marketed in bottles of circular cross-section, square or complex, allowing its storage and its application.
On distingue deux types de formulations de mascara, à savoir les formules dites "crème" et les formules résistant à l'eau dites "waterproof". Les flacons pour les formules crème sont réalisées en polyoléfine, notamment polyéthylène basse densité, polyéthylène haute densité, polypropylène, copolymère statistique de propylène. Ces polymères sont avantageux en matière de prix de revient. En revanche, ils ne conviennent pas pour les formules résistant à l'eau, car ils sont dégradés par les solvants organiques chimiquement agressifs contenus dans ces compositions. On utilise donc pour ces dernières des flacons en polychlorure de vinyle. Cependant, ce dernier polymère est plus coûteux que les polyoléfines et peut présenter des effets cancérigènes en raison de la présence de chlore dans sa molécule. De plus, son caractère corrosif rend nécessaire un traitement de surface protecteur du moule.There are two types of mascara formulations, namely so-called "cream" formulas and water-resistant formulas say "waterproof". Flasks for cream formulas are made of polyolefin, especially low polyethylene density, high density polyethylene, polypropylene, copolymer propylene statistics. These polymers are advantageous in terms of cost price. On the other hand, they are not suitable not for water-resistant formulas because they are degraded by chemically aggressive organic solvents contained in these compositions. So we use for these last polyvinyl chloride bottles. However, the latter polymer is more expensive than polyolefins and may cause carcinogenic effects due to presence of chlorine in its molecule. In addition, its character corrosive makes necessary a protective surface treatment of the mold.
Outre les inconvénients propres au PVC, l'utilisation de deux matières différentes nécessite de disposer de moules différents pour réaliser des flacons de même contenance, le PVC présentant moins de retrait au moulage que les polyoléfines.In addition to the disadvantages of PVC, the use of two different materials requires different molds to make bottles with the same capacity, PVC having less mold shrinkage than polyolefins.
Le but de l'invention est de remédier à ces inconvénients.The object of the invention is to overcome these disadvantages.
L'invention vise notamment un produit cosmétique du genre défini en introduction, et prévoit que ladite polyoléfine est réticulée. The invention aims in particular at a cosmetic product of the genus defined in the introduction, and provides that said polyolefin is crosslinked.
La réticulation, appliquée à l'une quelconque des polyoléfines utilisées pour le conditionnement du mascara crème, lui communique une résistance chimique qui la rend compatible avec le mascara résistant à l'eau. Le traitement de réticulation ne grève pratiquement pas le prix de revient des flacons, et permet d'utiliser ceux-ci indifféremment pour les deux types de mascara, tout en étant sûr en matière de santé et d'environnement.The crosslinking, applied to any one of the polyolefins used for the conditioning of the cream mascara, him communicates a chemical resistance that makes it compatible with water-resistant mascara. The crosslinking treatment hardly strike the cost price of flasks, and allows them to be used interchangeably for two types of mascara, while being safe in health and environment.

- Said ionizing radiation is beta radiation.
- Said ionizing radiation is gamma radiation.
- Said ionizing radiation is applied at a dose of between 3 and 150 kGy.
- Said ionizing radiation is applied at a dose of between 50 and 120 kGy.
L'invention a également pour objet un procédé pour obtenir un produit cosmétique tel que défini ci-dessus, dans lequel on expose audit rayonnement ionisant au moins un flacon en polyoléfine, et le cas échéant un conditionnement collectif contenant une multiplicité de tels flacons, et on remplit le ou les flacons de ladite composition cosmétique.The subject of the invention is also a method for obtaining a cosmetic product as defined above, in which one exposes to said ionizing radiation at least one polyolefin, and if necessary a collective conditioning containing a multiplicity of such flasks, and we fill the or the bottles of said cosmetic composition.
Les caractéristiques et avantages de l'invention sont exposés plus en détail dans la description ci-après.The features and advantages of the invention are exposed in more detail in the description below.
Un bombardement par des rayons bêta ou gamma permet de déclencher la réticulation d'une polyoléfine. Ce bombardement favorise la rupture des chaínes macromoléculaires et ainsi leur réorganisation en un réseau tridimensionnel saturé stable. Cette réticulation entraíne une modification du comportement mécanique, thermique et chimique.Bombardment with beta or gamma rays allows trigger the crosslinking of a polyolefin. This bombing promotes the breaking of macromolecular chains and so their reorganization into a saturated three-dimensional network stable. This crosslinking entails a modification of mechanical, thermal and chemical behavior.
Des essais ont mis en évidence qu'il est possible de fabriquer un flacon en polyéthylène réticulé par ionisation répondant à toutes les exigences de conditionnement du mascara résistant à l'eau.Tests have shown that it is possible to manufacture an ion-crosslinked polyethylene bottle meeting all the packaging requirements of the water resistant mascara.
Un exemple de réalisation de l'invention est décrit ci-après.An exemplary embodiment of the invention is described below.
On fabrique des flacons en polyéthylène haute densité destinés à du mascara résistant à l'eau, auxquels on fait subir toutes les opérations de production habituelles telles que décor, application de vernis, montage de l'essoreur. Les flacons terminés sont groupés dans des emballages collectifs tels que des cartons qui sont posés sur des palettes pour le transport. Les palettes sont alors présentées devant une source de cobalt 60 génératrice de rayons gamma. L'émission de rayonnement gamma permet de réaliser la réticulation des flacons sans nécessité de déconditionner. La dose reçue est comprise entre 3 et 150 kGy. Des essais ont montré qu'une dose comprise entre 50 et 120 kGy garantit l'insensibilité de la matière aux solvants contenus dans le mascara. High density polyethylene bottles are manufactured intended for water-resistant mascara, which are made undergo all the usual production operations such that decor, application of varnish, assembly of the wiper. The finished flasks are grouped together such as cartons that are placed on pallets for the transport. The pallets are then presented in front of a source of cobalt 60 generating gamma rays. The show gamma radiation makes it possible to crosslink the vials without the need to decondition. The dose received is between 3 and 150 kGy. Tests have shown that dose between 50 and 120 kGy guarantees the insensitivity of the solvent material contained in the mascara.
Les flacons sont alors prêts à être livrés par exemple à un laboratoire cosmétique qui les utilisera pour conditionner du mascara résistant à l'eau. En variante l'opération de réticulation peut être réalisée à n'importe quel stade intermédiare de la transformation et de la manipulation des flacons.The flasks are then ready to be delivered for example to a cosmetic laboratory that will use them to condition the water resistant mascara. In a variant, the operation of crosslinking can be carried out at any stage intermediary in the processing and manipulation of bottles.
Le résultat est similaire avec un bombardement de rayons bêta, mais dans ce cas il est nécessaire de retirer les cartons des palettes en raison de la moins bonne pénétration de ces rayons.The result is similar with ray bombardment beta, but in this case it is necessary to remove the pallets cartons due to poorer penetration of these rays.
