Abstract

This surface-active detergent composition essentially consists of an aqueous solution containing from 4 to 6 % by weight of a sodium alkylbenzene sulphonate, from 2.5 to 4.5 % by weight of sodium metasilicate pentahydrate and from 4 to 5.5 % by weight of a glycol ether.

Description

COMPOSITION DETERGENTE TENSIOACTIVE
La présente invention concerne une composition détergente tensioactive.
SURFACTANT DETERGENT COMPOSITION
The present invention relates to a surfactant detergent composition.

La nature des salissures de certaines pièces métalliques ou plastiques (huiles de trempe vieillies, graisses de roulement...) impose souvent, pour leur élimination, l'utilisation de solvants organiques; ceci pose des problèmes de sécurité (point d'éclair du solvant... toxicité éventuelle) ; d'autre part les résidus sont difficiles à éliminer dans les eaux résiduaires. The nature of the soiling of certain metallic or plastic parts (aged quenching oils, bearing greases, etc.) often requires, for their elimination, the use of organic solvents; this poses safety problems (flash point of the solvent ... possible toxicity); on the other hand the residues are difficult to remove in the waste water.

Le dégraissage de ces pièces à l'aide de détergents aqueux fortement alcalins n'est pas toujours possible. Degreasing of these parts with strongly alkaline aqueous detergents is not always possible.

La présente invention s'est donné pour objet de mettre au point ul-l détergent industriel polyfonctionnel, utilisable en milieu aqueux, qui procure une action dégraissante comparable à celle de certains solvants pétroliers, sans toutefois présenter une alcalinité agressive. The object of the present invention is to develop ul-l polyfunctional industrial detergent, usable in aqueous medium, which provides a degreasing action comparable to that of certain petroleum solvents, without however exhibiting an aggressive alkalinity.

L'inventeur a découvert que l'introduction dans une composition à base de produits mouillants, et notamment de produits anioniques, d'une certaine quantité d'éther de glycol permettait d'améliorer de façon surprenante les propriétés de dispersion et de pénétration du détergent ainsi obtenu. The inventor has discovered that the introduction into a composition based on wetting products, and in particular anionic products, of a certain amount of glycol ether made it possible to surprisingly improve the dispersion and penetration properties of the detergent thus obtained.

L'invention a donc pour objet une composition détergente tensioactive, qui est caractérisée en ce qu'elle est essentiellement constituée d'une solution aqueuse contenant de 4 à 6 % en poids d'un alkylbenzène sulfonate de sodium, de 2,5 à 4,5 % en poids de métasilicate de sodium pentahydraté et de 4 à 5,5 % en poids d'un éther de glycol. The subject of the invention is therefore a surfactant detergent composition, which is characterized in that it essentially consists of an aqueous solution containing from 4 to 6% by weight of a sodium alkylbenzene sulfonate, from 2.5 to 4 , 5% by weight of sodium metasilicate pentahydrate and from 4 to 5.5% by weight of a glycol ether.

Selon un mode de réalisation préféré de l'invention, l'éther de glycol est le méthyléther de dipropylèneglycol et l'alkylbenzène sulfonate de sodium est le dodécylbenzène sulfonate de sodium. According to a preferred embodiment of the invention, the glycol ether is dipropylene glycol methyl ether and the sodium alkylbenzene sulfonate is sodium dodecylbenzene sulfonate.

Cet éther de glycol miscible à l'eau joue un rôle d'agent couplant pour l'alkylbenzène sulfonate, ce qui garantit la stabilité de ce produit en solution aqueuse et améliore les propriétés dispersantes communiquées à ladite solution aqueuse par ce composé anionique. This water-miscible glycol ether acts as a coupling agent for the alkylbenzene sulfonate, which guarantees the stability of this product in aqueous solution and improves the dispersing properties communicated to said aqueous solution by this anionic compound.

Sa faible tension superficielle améliore par ailleurs l'aptitude à la pénétration de la solution dans les dépôts à éliminer. Its low surface tension also improves the ability of the solution to penetrate the deposits to be removed.

La composition détergente selon l'invention se présente sous la forme d'un liquide jaune, limpide ; elle est conforme aux normes françaises de biodégradabilité et de toxicité ; elle présente un intérêt tout particulier dans les cas difficiles où l'on ne peut utiliser les solvants ou les détergents fortement alcalins.  The detergent composition according to the invention is in the form of a clear yellow liquid; it complies with French biodegradability and toxicity standards; it is of particular interest in difficult cases where solvents or strongly alkaline detergents cannot be used.

La présente invention sera mieux comprise et ses avantages ressortiront bien de l'exemple qui suit qui l'illustre sans nullement la limiter. The present invention will be better understood and its advantages will emerge clearly from the example which follows which illustrates it without in any way limiting it.

On prépare une solution aqueuse ayant la composition suivante
%en poids
- Dodécylbenzène sulfonate de sodium ............... 5,23 %
- Métasilicate de sodium pentahydraté .............. 3,8 %
- Méthyléther du dipropylène glycol .................. 4,6 %
- Eau ........................................ 86,37 %
La densité à 20 C de la solution obtenue est de 1,025 Kg/dm3 et le pH est de 13.
An aqueous solution having the following composition is prepared
%in weight
- Sodium dodecylbenzene sulfonate ............... 5.23%
- Sodium metasilicate pentahydrate .............. 3.8%
- Methyl ether of dipropylene glycol .................. 4.6%
- Water ........................................ 86.37%
The density at 20 C of the solution obtained is 1.025 Kg / dm3 and the pH is 13.

On applique cette solution à l'état pur au pinceau ou par immersion sur les installations en service, à froid ou mieux encore à 50 C, et l'on arrive à éliminer complètement les dépôts gras sur les pièces, qu'il s'agisse de pièces métalliques (métaux ferreux ou non ferreux) ou de pièces en matière plastique, et quelque soit la nature des salissures : huile de trempe vieillie, graisse de roulement... Le détergent peut, bien évidemment, être également appliqué sous forme dilué. This solution is applied in the pure state by brush or by immersion on installations in service, cold or better still at 50 C, and we manage to completely remove fatty deposits on the parts, whether metallic parts (ferrous or non-ferrous metals) or plastic parts, and whatever the nature of the soiling: aged quenching oil, bearing grease, etc. The detergent can, of course, also be applied in diluted form.

La durée de l'immersion est fonction du point de fusion de la salissure et du degré d'agitation du bain de dégraissage. Suivant-le degré de propreté désiré ou l'utilisation ultérieure, on peut rincer à l'eau froide ou à l'eau tiède les pièces nettoyées par le détergent selon l'invention. The duration of the immersion depends on the melting point of the soiling and the degree of agitation of the degreasing bath. Depending on the degree of cleanliness desired or subsequent use, the parts cleaned with the detergent according to the invention can be rinsed with cold water or lukewarm water.

Le rinçage peut se faire par aspersion ou par immersion. L'agitation du bain provoquera la mise en émulsion du film gras protecteur qui subsiste après le dégraissage. La surface métallique après rinçage est exempte de produits gras. Rinsing can be done by sprinkling or immersion. Agitation of the bath will cause the protective fatty film which remains after degreasing to be emulsified. The metal surface after rinsing is free of greasy products.

Les eaux de lavage ou de rinçage peuvent être collectées dans un bac à cloisons qui permet la récupération des graisses et le rejet de la phase aqueuse, sans poser de problèmes d'eaux résiduaires. The washing or rinsing water can be collected in a partition tank which allows the recovery of grease and the rejection of the aqueous phase, without posing any waste water problems.

I1 faut par ailleurs noter que l'absence de point d'éclair de la solution aqueuse du détergent selon l'invention permet un stockage ne nécessitant pas de précautions particulières.  It should also be noted that the absence of a flash point in the aqueous solution of the detergent according to the invention allows storage not requiring any special precautions.
