Description
La présente invention concerne l'utilisation en tant qu'agent de nettoyage d'une association d'un mélange d'esters méthyliques d'acides gras en C16-C20 d'huile de ricin avec au moins un glycéride éthoxylé, ainsi que des compositions comprenant une telle association.The present invention relates to the use as a cleaning agent of a combination of a mixture of C 16 -C 20 fatty acid methyl esters of castor oil with at least one ethoxylated glyceride, as well as compositions comprising such an association.
Les produits utilisés couramment pour nettoyer les taches de graisses, d'huiles, d'encres ou encore de dérivés pétroliers sont souvent à base d'hydrocarbures qui sont préparés à partir du pétrole ou sont fortement alcalins.The products commonly used to clean grease stains, oils, inks or petroleum derivatives are often based on hydrocarbons that are prepared from petroleum or are highly alkaline.
Du fait de l'impact néfaste de ces produits sur l'environnement et sur la santé des personnes, des produits plus écologiques ont été développés à base d'huile de tournesol ou de soja. Cependant, ces produits présentent le désavantage de laisser un film brillant et gras après utilisation.Due to the negative impact of these products on the environment and on the health of people, more ecological products have been developed based on sunflower oil or soya. However, these products have the disadvantage of leaving a glossy and greasy film after use.
Les inventeurs ont alors découvert de manière surprenante que les esters méthyliques d'acides gras en C16-C20 d'huile de ricin présentaient un fort pouvoir solvant tout en laissant après utilisation un film satiné et sec qui semble en outre jouer un rôle protecteur, notamment en diminuant l'oxydation des surfaces métalliques. Les esters méthyliques d'acides gras en C16-C20 d'huile de ricin sont de plus biodégradables et ne sont donc pas néfastes pour l'environnement. Le ricin présente l'intérêt supplémentaire de pousser sur des terres non arables.The inventors then surprisingly discovered that the castor oil C 16 -C 20 fatty acid methyl esters had a high solvent power while leaving after use a satin and dry film which also seems to play a protective role. , in particular by reducing the oxidation of the metal surfaces. The methyl esters of C 16 -C 20 fatty acids castor oil are moreover biodegradable and are therefore not harmful to the environment. Castor has the added benefit of growing on non-arable land.
L'utilisation de glycérides éthoxylés permet en outre d'obtenir des compositions émulsionnables et d'augmenter le pouvoir nettoyant d'une telle composition. En effet, en plus d'être un agent émulsionnant, ce type de tensioactif non ionique présente l'avantage d'être un très bon agent anti-tâche. Il possède également les propriétés d'un agent non moussant et/ou viscosant (c'est-à-dire augmentant la viscosité d'une composition).The use of ethoxylated glycerides also makes it possible to obtain emulsifiable compositions and to increase the cleaning power of such a composition. Indeed, in addition to being an emulsifying agent, this type of nonionic surfactant has the advantage of being a very good anti-stain agent. It also has the properties of a non-foaming and / or viscosifying agent (i.e. increasing the viscosity of a composition).
Les compositions comprenant une telle association d'esters méthyliques d'acides gras en C16-C20 d'huile de ricin et d'au moins un glycéride éthoxylé présente l'avantage supplémentaire d'avoir un pH neutre.Compositions comprising such a combination of C 16 -C 20 fatty acid methyl esters of castor oil and at least one ethoxylated glyceride have the additional advantage of having a neutral pH.
La présente invention a ainsi pour premier objet l'utilisation en tant qu'agent de nettoyage d'une association d'un mélange d'esters méthyliques d'acides gras en C16-C20 d'huile de ricin, pour lequel les acides gras en C18 représentent au moins 70% en poids du poids total du mélange d'acides gras en C16-C20 d'huile de ricin, avec au moins un glycéride éthoxylé.The present invention thus has as its first object the use as cleaning agent of a combination of a mixture of C 16 -C 20 fatty acid methyl esters of castor oil, for which the acids C 18 fatty acids represent at least 70% by weight of the total weight of the C 16 -C 20 fatty acid mixture of castor oil, with at least one ethoxylated glyceride.

Les compositions comprenant une telle association sont donc émulsionnables.The mixture of C 16 -C 20 fatty acid methyl esters of castor oil, for which the C 18 fatty acids represent at least 70% by weight of the total weight of the C 16 fatty acid mixture C 20 castor oil, is especially useful as cleaning and degreasing and ethoxylated glyceride is useful both as a cleaning agent and emulsifier. The compositions comprising such an association are therefore emulsifiable.

Ces acides gras ne comprennent donc pas l'acide ricinoléique qui ne peut être considéré comme un acide gras puisqu'il comprend une fonction hydroxy (OH) sur sa chaîne latérale. Ils comprendront en outre majoritairement des acides gras en C16 et C18 (au moins 80%, de préférence au moins 90%, et encore de préférence au moins 95% en poids par rapport au mélange d'acides gras). Les acides gras en C18 comprendront plus particulièrement de l'acide stéarique, de l'acide oléique, de l'acide linoléique et de l'acide linolénique, et les acides gras en C16 comprendront plus particulièrement de l'acide palmitique.

These fatty acids therefore do not include ricinoleic acid which can not be considered as a fatty acid since it comprises a hydroxyl (OH) function on its side chain. They will also comprise mainly C 16 and C 18 fatty acids (at least 80%, preferably at least 90%, and more preferably at least 95% by weight relative to the fatty acid mixture). C 18 fatty acids will include more particularly stearic acid, oleic acid, linoleic acid and linolenic acid, and C 16 fatty acids will more particularly include palmitic acid.

La présente invention sera mieux comprise à la lumière des exemples non limitatifs qui suivent.The present invention will be better understood in the light of the nonlimiting examples which follow.
Les compositions C1 à C4 selon l'invention décrites dans les tableaux suivants ont été préparées. Elles sont plus adaptées pour de gros pour des gros travaux, pour nettoyer et dégraisser des surfaces dures très sales et/ou très grasses comme des moteurs, des outils, des cuves à fuel, etc. ou encore comme dégrippant (composition C1).
La composition C5 selon l'invention décrite dans le tableau suivant a été préparée. Elle est plus adaptée pour un nettoyage de surfaces dures peu sales et/ou peu grasses. Elle sera avantageusement utilisée sous une forme diluée dans l'eau de 2 à 5%, voire jusqu'à 20% pour des taches plus difficiles à nettoyer.
Les trois formulations A à C à base d'un mélange d'esters méthyliques d'acides gras d'huile de ricin ont été préparées. Les pourcentages sont donnés en poids par rapport au poids total de la formulation.
Les compositions A, B et C ont alors été testées en comparaison avec des compositions de l'art antérieur à base d'huile de tournesol :
- ■ Composition X constituée d'huile de tournesol pure, et
- ■ Composition Y : composition émulsionnable à base d'huile de tournesol (commercialisée sous le nom Neutralène® 2006E par la société TEC Industrie).
- ■ Composition X consisting of pure sunflower oil, and
- ■ Composition Y: an emulsifiable composition based on sunflower oil (marketed under the name Neutralène ® 2006 E by TEC Industrie).
Sur des plaques de verre blanc, sont appliquées en couche épaisse de 0,5 à 2 mm d'épaisseur :
- ■ de l'huile semi-synthétique commercialisée sous le nom Perfo 10 W 40 par la société Lubro,
- ■ de la graisse au bisulfure de molybdène 104 commercialisée par la société Lubro, et
- ■ une émulsion liquide de bitume solvanté commercialisée sous le nom Blacksol® par la société Technique-Béton.
- ■ semi-synthetic oil marketed under the name Perfo 10 W 40 by Lubro,
- Molybdenum disulfide grease 104 sold by the company Lubro, and
- ■ Solvent a bitumen liquid emulsion marketed under the name Blacksol ® by the company Technical-Concrete.
Les compositions A, B, C, X et Y ont alors été appliquées par pulvérisation, les compositions A, B et X étant utilisés pures tandis que les compositions émulsionnables C et Y étant utilisées sous forme diluées dans l'eau à 30%.Compositions A, B, C, X and Y were then applied by spraying, compositions A, B and X being used pure while emulsifiable compositions C and Y being used in diluted form in water at 30%.
Après 5 à 10 min, la surface du verre est essuyée avec un papier d'essuyage ouaté, puis avec un papier d'essuyage imbibé de la composition dans le cas du bitume.After 5 to 10 minutes, the surface of the glass is wiped with a wiped wiping paper, then with a wiping paper impregnated with the composition in the case of bitumen.
L'aspect de la surface du verre a alors été observé juste après l'étape d'essuyage (T0) puis après 5 minutes (T5).The appearance of the glass surface was then observed just after the wiping step (T0) and then after 5 minutes (T5).
Dans le cas des compositions émulsionnables C et Y, la surface du verre a alors été rincée à l'eau puis séchée au papier d'essuyage.In the case of emulsifiable compositions C and Y, the surface of the glass was then rinsed with water and then dried with wiping paper.
L'aspect de la surface du verre a alors été observé (TR).The appearance of the glass surface was then observed (TR).
Les résultats observés sont décrits dans le tableau suivant :
Les compositions A et X, et C et Y ont été comparées entre elles du fait de leur similitude de formulation. On constate ainsi que les compositions à base d'un mélange d'esters d'acides gras d'huile de ricin ont un meilleur pouvoir dégraissant que les compositions à base d'huile de tournesol.Compositions A and X, and C and Y were compared with one another because of their similarity of formulation. It is thus found that the compositions based on a mixture of castor oil fatty acid esters have a better degreasing power than the compositions based on sunflower oil.
Trois plaques d'acier de 5 x 10 cm ont été plongées chacune directement dans la composition A, B ou X utilisée pure, puis égouttées. Une quatrième plaque d'acier n'a été plongée dans aucune composition afin de servir de témoin.Three 5 x 10 cm steel plates were each dipped directly into the pure composition A, B or X and then drained. A fourth steel plate was not immersed in any composition to serve as a control.
Les plaques ont ensuite été immergées dans une solution d'acide sulfurique à 0,5% pendant 24h.The plates were then immersed in a 0.5% sulfuric acid solution for 24 hours.
Une fois sorties de la solution acide, les plaques ont été laissées à sécher à l'air libre à température ambiante pendant 1 heure.Once removed from the acidic solution, the plates were allowed to air dry at room temperature for 1 hour.
Les inventeurs ont alors pu faire les observations suivantes :
- ■ Un dégagement gazeux est observé à la surface de la plaque d'acier dès l'immersion de celle-ci dans la solution acide pour la plaque témoin, après 30 minutes pour la plaque ayant été plongée dans la composition B et après 1 heure pour les plaques ayant été plongées dans la composition A ou X.
- ■ Concernant le degré d'oxydation, la plaque témoin est complètement oxydée (formation d'oxyde de fer III de couleur rouge orangé), la plaque ayant été plongée dans la composition X est très oxydée mais a été partiellement protégée comparativement à la plaque témoin, et les plaques ayant été plongées dans les compositions A et B sont peu oxydées, seules des piqûres d'oxydations espacées et peu nombreuses étant observées.
- ■ Gaseous evolution is observed on the surface of the steel plate as soon as it is immersed in the acid solution for the control plate, after 30 minutes for the plate having been immersed in the composition B and after 1 hour for the plates having been immersed in composition A or X.
- With regard to the degree of oxidation, the control plate is completely oxidized (formation of iron oxide III orange-red), the plate having been immersed in the composition X is highly oxidized but has been partially protected compared to the control plate , and the plates having been immersed in the compositions A and B are little oxidized, only spaced and few oxidation pits being observed.
On constate ainsi que la présence d'un mélange d'esters d'acides gras d'huile de ricin apporte une meilleure protection anti-corrosion que l'huile de tournesol.It is thus found that the presence of a mixture of castor oil fatty acid esters provides a better anti-corrosion protection than sunflower oil.
Les compostions C et Y ont été diluées à 30% avec de l'eau et mélangées pour former une émulsion. Les compositions ont alors été laissées au repos.Compositions C and Y were diluted 30% with water and mixed to form an emulsion. The compositions were then left to stand.
On constate alors que la composition X émulsionnée commence à déphaser après 15 minutes et est complètement séparée en deux phases après 1 heure.It is then found that the emulsified composition X begins to shift after 15 minutes and is completely separated into two phases after 1 hour.
Au contraire, la composition C émulsionnée commence à déphaser après 30 minutes et n'est toujours pas séparée en deux phases après 1 semaine.On the other hand, the emulsified composition C starts to shift out after 30 minutes and is still not separated into two phases after 1 week.
Une peinture glycérophtalique a été déposée sur une plaque de verre et laissée sécher pendant 24h.A glycerophthalic paint was deposited on a glass plate and allowed to dry for 24 hours.
Plusieurs spots de 5 gouttes de chaque composition A ou X ont alors été déposées sur la plaque de verre à intervalles réguliers. Toutes les minutes, un spot de chaque composition (A et X) a été essuyé avec un chiffon de manière à voir si la peinture avait été solubilisée à l'endroit de l'application de la composition.Several spots of 5 drops of each composition A or X were then deposited on the glass plate at regular intervals. Every minute, a spot of each composition (A and X) was wiped with a cloth so as to see if the paint had been solubilized at the location of the application of the composition.
On observe alors que la peinture est totalement solubilisée après 5 minutes avec la composition A alors qu'elle n'est solubilisée qu'après 11 minutes avec la composition X.It is then observed that the paint is completely solubilized after 5 minutes with the composition A whereas it is solubilized only after 11 minutes with the composition X.
Une surface en plastique moulé granuleux est frottée en aller-retour sur une aire d'environ 10 x 30 cm avec un papier d'essuyage imbibé de la composition A, B ou X. On laisse au repos pendant 30 minutes avant d'observer la surface.A granular molded plastic surface is rubbed back and forth over an area of about 10 x 30 cm with a wiping paper soaked in composition A, B or X. It is allowed to stand for 30 minutes before observing. area.
On constate que la composition à base d'huile de tournesol a laissé un film brillant et gras, tandis que la composition à base d'un mélange d'esters d'acides gras d'huile de ricin a laissé un film satiné, sec et non gras.It is found that the sunflower oil-based composition left a glossy and greasy film, while the composition based on a mixture of castor oil fatty acid esters left a satin film, dry and not fat.
La nature grasse ou non grasse du film a été contrôlée en appliquant un papier sur la surface en plastique et en observant la formation ou non d'une tâche grasse bien reconnaissable sur le papier.The oily or non-greasy nature of the film was controlled by applying paper to the plastic surface and observing the formation or otherwise of a recognizable greasy work on the paper.
