Abstract
Description
La présente invention est relative à de nouvelles compositions antimousses qui se présentent sous forme de granulés et sont notamment destinées à autre associées à des lessives en poudre. The present invention relates to new anti-foam compositions which are in the form of granules and are in particular intended for others associated with powdered detergents.
Les excellentes propriétés antimousses des huiles de silicone sont bien connues. Toutefois, il n'est pas possible d'utiliser ces huiles de silicone en association avec des lessives en poudre, en raison de l'agressivité des lessives à l'égard de ces composés, dont les propriétés antimousses sont détruites lorsqu'on les mélange avec des lessives en poudre. The excellent defoaming properties of silicone oils are well known. However, it is not possible to use these silicone oils in combination with powdered detergents, because of the aggressiveness of the detergents with respect to these compounds, the antifoam properties of which are destroyed when mixed with powder detergents.
Il est par ailleurs connu d'incorporer divers produits antimousses dans les lessives en poudre , toutefois, ces produits ont une activité antimousse moins efficace que l'huile de silicone. D'autres compositions connues à base d'huile de silicone ne sont actives que dans des bains de lessive portés à des températures relativement élevées, d'au moins 500 C, ce qui représente un inconvénient préjudiciable, notamment pour le lavage en machine, la mousse de la lessive ayant amplement le temps de se développer avant que le bain n'ait atteint une température de 500 C, l'action tardive, à partir de 500 C, du produit antimousse incorporé à la lessive, n'ayant, de ce fait, que peu d'efficacité. It is also known to incorporate various anti-foaming products in powdered detergents, however, these products have less effective anti-foaming activity than silicone oil. Other known compositions based on silicone oil are only active in detergent baths brought to relatively high temperatures, of at least 500 ° C., which represents a detrimental drawback, in particular for machine washing, detergent foam having ample time to develop before the bath has reached a temperature of 500 C, the late action, from 500 C, of the antifoam product incorporated in the detergent, having, as a result fact, that little efficiency.
La présente invention s'est en conséquence donné pour but de pourvoir à de nouvelles compositions antimousses à base d'huile de silicone qui répondent mieux aux nécessités de la pratique que les compositions antimousses antérieurement connues, notamment en ce qu'elles assurent une protection totale et efficace de l'huile de silicone à l'égard de l'action destructrice des lessives dans lesquelles ladite huile de silicone est incorporée et en ce qu'elles permettent, lorsqu'elles sont incorporées à une lessive en poudre, la libération de l'agent antimousse proprement dit, à savoir l'huile de silicone, à des températures égales ou supérieures à 200 C, dans le bain de lessive. The present invention has therefore given itself the aim of providing new antifoam compositions based on silicone oil which better meet the needs of the practice than the previously known antifoam compositions, in particular in that they provide total protection and effective of the silicone oil with regard to the destructive action of the detergents in which the said silicone oil is incorporated and in that they allow, when they are incorporated into a powdered detergent, the release of the the actual defoaming agent, namely silicone oil, at temperatures of 200 C or higher, in the laundry bath.
La présente invention a pour objet une nouvelle composition antimousse, caractérisée en ce qu'elle est constituée par un mélange d'huile de silicone présentant des propriétés antimousses et d'au moins un composé présentant des propriétés adsorbantes hydrophile ou soluble dans l'eau sensiblement à la température ambiante, lequel mélange est mis sous forme de granulés enrobés d'un revêtement d'au moins un composé hydrophile ou soluble dans l'eau sensiblement à la température ambiante, présentant des propriétés adsorbantes, et éventuellement d'un revêtement protecteur. The subject of the present invention is a new antifoaming composition, characterized in that it consists of a mixture of silicone oil having antifoaming properties and of at least one compound having substantially hydrophilic or water-soluble adsorbent properties. at room temperature, which mixture is formed into granules coated with a coating of at least one hydrophilic or water-soluble compound substantially at room temperature, having adsorbent properties, and optionally with a protective coating.
Selon un mode de réalisation avantageux de la nouvelle composition antimousse conforme à l'invention, le composé hydrophile ou hydrosoluble présentant des propriétés adsorbantes est pris dans le groupe qui comprend les sucres, et notamment le lactose, le saccharose, le mannitol, le glucose, les amidons et leurs dérivés, les sels minéraux micronisés tels, notamment, que le chlorure de sodium, le bicarbonate de sodium, le carbo nate de sodium, ainsi que les farines de blé et de mais. According to an advantageous embodiment of the new anti-foaming composition in accordance with the invention, the hydrophilic or water-soluble compound having adsorbent properties is taken from the group which comprises sugars, and in particular lactose, sucrose, mannitol, glucose, starches and their derivatives, micronized mineral salts such as, in particular, sodium chloride, sodium bicarbonate, sodium carbo nate, as well as wheat and corn flours.
Selon un autre mode de réalisation avantageux de la nouvelle composition antimousse conforme à l'invention, le composé hydrophile ou hydrosoluble présentant des propriétés adsorbantes tel que sucre, sel minéral micronisé ou farine de blé ou de mais, est associé à un autre composé présentant des propriétés adsorbantes, qui retarde la dissolution ou analogue du premier composé dans l'eau, cet autre composé étant avantageusement pris dans le groupe qui comprend notamment le talc, les alumines adsorbantes, les silices colloidales, les résines naturelles ou synthétiques telles que la gomme laque ou les polymères méthacryliques. According to another advantageous embodiment of the new antifoaming composition in accordance with the invention, the hydrophilic or water-soluble compound having adsorbent properties such as sugar, micronized mineral salt or wheat or corn flour, is combined with another compound having adsorbent properties, which delays the dissolution or the like of the first compound in water, this other compound being advantageously taken from the group which comprises in particular talc, adsorbent aluminas, colloidal silicas, natural or synthetic resins such as shellac or methacrylic polymers.
La présente invention a également pour objet un procédé de fabrication de la nouvelle composition antimousse contenant de l'huile de silicone sous forme de granulés, caractérisé en ce qu'on mélange de l'huile de silicone avec un composé présentant des propriétés adsorbantes, hydrophile ou soluble dans l'eau sensiblement à la température ambiante, en ce que l'on extrude la pâte visqueuse formée, pour obtenir un cordon collant, en ce qu'on dépose ce cordon collant sur un composé présentant des propriétés adsorbantes, hydrophile ou soluble dans l'eau sensiblement à la température ambiante, pour enrober ledit cordon d'un revêtement dudit composé, qui le rend non-collant, en ce qu'on soumet ledit cordon non-collant, dans un milieu essentiellement constitué par ledit compose adsorbant hydrophile ou hydrosoluble, à une agitation ou analogue vigoureuse qui provoque la rupture du cordon en granulés, qui sont reçus dans un milieu essentiellement constitué par ledit composé adsorbant hydrophile ou hydrosoluble et mouillés par de l'eau pour solubiliser la partie superficielle du revêtement de composé adsorbant hydrophile ou hydrosoluble et provoquer, après évaporation de l'eau, la formation d'une pellicule dudit composé solide cristallisé, donnant lieu ainsi à des granulés contenant de l'huile de silicone, enrobés d'une couche protectrice, qui présentent une activité antimousse élevée à partir de températures relativement basses, de l'ordre de 200C notamment. The present invention also relates to a process for manufacturing the new antifoam composition containing silicone oil in the form of granules, characterized in that silicone oil is mixed with a compound having adsorbent, hydrophilic properties. or soluble in water substantially at room temperature, in that the viscous paste formed is extruded, in order to obtain a sticky bead, in that this sticky bead is deposited on a compound having adsorbent, hydrophilic or soluble properties in water substantially at room temperature, to coat said bead with a coating of said compound, which makes it non-sticky, in that said non-sticky bead is subjected, in a medium essentially constituted by said hydrophilic adsorbent compound or water-soluble, to vigorous stirring or the like which causes the granular cord to rupture, which are received in a medium essentially consisting of said hydrophilic adsorbent compound or water-soluble and wetted with water to dissolve the surface part of the coating of hydrophilic or water-soluble adsorbent compound and cause, after evaporation of the water, the formation of a film of said crystallized solid compound, thus giving rise to granules containing silicone oil, coated with a protective layer, which exhibit a high defoaming activity from relatively low temperatures, of the order of 200C in particular.
Selon un mode de réalisation avantageux de ce procédé, on sélectionne les dimensions des granulés par rupture du cordon extrudé et enrobé,par tous moyens appropriés,et notamment par tamisage ou micronisation. According to an advantageous embodiment of this process, the dimensions of the granules are selected by breaking the extruded and coated bead, by any suitable means, and in particular by sieving or micronization.
Selon un autre mode de réalisation avantageux de ce procédé, la protection des granulés est renforcée par application sur les granulés terminés, d'un revêtement de gomme, de résine ou d'un composé adsorbant hydrophile ou soluble dans l'eau à des tespératures relativement basses. According to another advantageous embodiment of this process, the protection of the granules is reinforced by applying to the finished granules, a coating of gum, resin or a hydrophilic or water-soluble adsorbent compound at relatively low temperatures. low.
Outre les dispositions qui précèdent, l'invention ccnnren1 encore d'autres dispositions,qui ressortiront de la description qui va suivre. In addition to the foregoing arrangements, the invention also provides other arrangements which will become apparent from the description which follows.

EXEMPLE 1
On mélange intimement 120g d'huile de silicone (qualite Entschaümer Article 7743 commercialisée par la Société MERCK AG) avec 80 g de lactose. On obtient ainsi une pâte visqueuse que l'on extrude à travers une filière d'l nin de diamètre environ pour obtenir un cordon collant que l'on dépose sur un excès de lactose pulvérulent pour l'enrober d'un revêtement de lactose et le rendre non collant. Toujours en milieu l a c t o s e p u l v é r u 1 e n t, on soumet le cordon à une agitation vogoureuse pour le fragmenter en granulés. On obtient ainsi, après tamisage à travers un tamis ASTM18, 333 g de granulés que l'on mouille avec 11 g d'eau.On sèche dans une turbine et on recueille les granulés terminés qui contiennent de l'huile de silicone à propriétés antimousses et sont enrobés d'un revêtement de lactose cristallisé pratiquement pur.EXAMPLE 1
Intimately mixing 120 g of silicone oil (quality Entschaümer Article 7743 sold by the company MERCK AG) with 80 g of lactose. A viscous paste is thus obtained which is extruded through a die of about one nin diameter in order to obtain a sticky bead which is deposited on an excess of powdered lactose to coat it with a coating of lactose and the make it non-sticky. Still in a lactose-pulped medium, the cord is subjected to vigorous agitation in order to fragment it into granules. 333 g of granules which are wetted with 11 g of water are thus obtained, after sieving through an ASTM18 sieve, dried in a turbine and collected in the finished granules which contain silicone oil with anti-foaming properties. and are coated with a substantially pure crystallized lactose coating.
Ces granulés sont incorporés dans une lessive en poudre et exercent, lorsque la lessive ainsi formée est introduite dans de l'eau, une action antimousse optimale à des températures aussi basses que 200 C. These granules are incorporated into a powder detergent and exert, when the detergent thus formed is introduced into water, an optimal defoaming action at temperatures as low as 200 C.
EXEMPLE 2
On mélange intimement 50 g de chlorure de sodium microni i sé avec 50 g d'huile de silicone présentant des propriétés antimousses. On obtient ainsi une pâte visqueuse que l'on extrude à travers une filière d'l mm de diamètre environ, pour obtenir un cordon collant que l'on dépose sur un excès de lactose pulvérulent pour l'enrober d'un revêtement de lactose et le rendre non-collant. Toujours en milieu lactose, on soumet le cordon à une agitation vigoureuse pour le fragmenter en granulés.EXAMPLE 2
50 g of micronized sodium chloride are intimately mixed with 50 g of silicone oil having anti-foaming properties. A viscous paste is thus obtained which is extruded through a die of approximately 1 mm in diameter, in order to obtain a sticky bead which is deposited on an excess of powdered lactose to coat it with a coating of lactose and make it non-sticky. Still in a lactose medium, the bead is subjected to vigorous stirring to break it up into granules.
On obtient ainsi, après tamisage à travers un tamis ASTM 18, 150 g de granulés que l'on mouille avec 10 g d'eau. Après séchage dans une turbine, on recueille les granulés terminés qui, incorporés à des lessives, exercent leurs propriétés antimousses dans des bains à partir de températures aussi basses que 200 C environ.There is thus obtained, after sieving through an ASTM 18 sieve, 150 g of granules which are wetted with 10 g of water. After drying in a turbine, the finished granules are collected which, incorporated into detergents, exert their anti-foaming properties in baths from temperatures as low as about 200 ° C.
EXEMPLE 3

Toujours en milieu chlorure de sodium mi croisé, on soumet le cordon à une agitation vigoureuse pour le fragmenter en granulés. On obtient, après tamisage à travers un tamis
ASTM 18, 150 g d e g r a n u 1 é s q u e 1 ' o n mouille avec 10 g d'eau.Après séchage dans une turbine, on recueille les granulés terminés, qui, incorporés à des lessives, exercent dans un bain d'eau, leurs propriétés antimousses à partir de 200 C environ.EXAMPLE 3
50 g of micronized sodium chloride are intimately mixed with 50 g of silicone oil having anti-foaming properties. A viscous paste is thus obtained which is extruded through a die of about 1 mm diameter, to obtain a sticky bead which is deposited on an excess of micronized sodium chloride in order to coat it with a coating of sodium chloride and make it non-sticky. Still in the mid-cross sodium chloride medium, the cord is subjected to vigorous stirring to break it up into granules. After sieving through a sieve,
