Description

Use of terpenic compounds polyoxypropylene / polyoxyethylene as degreasing agents of hard surfaces.

The present invention aims at the use of terpenic compounds comprising moieties oxypropylene and oxyethylene, as agents of degreasing / cleaning of hard surfaces, and more particularly metal surfaces

The scope of cleaning / degreasing of metal surfaces require very high performance, especially in regard to the degreasing power of the composition used, as well as its ability not to foam. It should also be noted that these results are required very Often although application conditions are very difficult. Thus, spray methods are very favorable to the formation of foam, because the treatment bath is applied under Pressure.

The compounds currently used in this scope are mostly ethoxylated alkylphenols. These compounds have intrinsically degreasing properties very satisfying However, they present an important inconvenient, to favor the formation of foam. This phenomenon  redhibitory in this application, it is decreased by the addition of a antifoaming agent, such as for example linear alcohols alkoxylated However, the presence of this type of compound decreases in a non-negligible way, and this definitely, the Degreasing activity of ethoxylated alkylphenol. In effect, it is not possible to compensate for the loss of activity by an addition supplemental alkylphenol, so as to recover the level of initial activity

In the international patent application WO 96/01245 described alkoxylated terpenic compounds presented as good degreasers that favor the formation of foam. The exemplified compounds are derived from the compounds nopol or arbanol type terpenics, and comprise 0 to 2 oxypropylene residues and 3.3 to 10.3 oxyethylene moieties.

These compounds whose interest is not in doubt here, they do not give, however, good results in the application, very particular, of the treatment of hard surfaces and, especially metallic. In effect, they do not respond simultaneously to the two criteria required in this area, which have a high degreasing activity and an unfavorable training action of foam This results in making the increase necessary of the compound content in the formulation and / or the addition of a antifoam agent, with the drawbacks that are already known. In addition, it is required that despite the addition of quantities important of these compounds, degreasing levels achieved are at most equivalent to those of alkylphenols ethoxylated.

As can be seen, it is necessary to be able to have compounds whose degreasing power is very high, and other than the origin of the formation of a foam level important. The use of said compounds would present the double advantage of not requiring the use of quantities important of this compound, nor the addition of compounds supplementary, as antifoaming agents.

The present invention aims to propose the use of a particular terpenic compound, which satisfies at the double criteria mentioned above, in the application of the cleaning / degreasing of hard surfaces and, especially, of metal surfaces, and this, in low concentrations.

Thus, the present invention aims at the use for cleaning / degreasing hard surfaces of at least one compound, used with a concentration comprised between 0.01 and 10 g / l, during the use of the latter, of following formula:
