Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composition for cleaning hard surfaces which cleans surfaces and further prevents or inhibits surface contamination.

[0002]

2. Description of the Related Art Conventionally, when hard surfaces such as wood, glossy tiles, and painted metal are cleaned in the conventional manner, dirt is removed using a surfactant or a solvent-based composition.
It is known that the lacquer, wax or abrasive is applied as a separate operation to seal and protect the surface and reduce the rate of soil re-attachment. This 2-
Process cleaning and sealing operations are time consuming and complex.

It has been proposed to include a wide variety of so-called "soil release agents" in cleaning compositions which include polymers, siloxanes and quaternary surfactants to provide a secondary cleaning action. These soil release agents appear to function by depositing a layer of polymer, siloxane or surfactant on the surface during cleaning. It is believed that this layer of material further facilitates the cleaning operation by reducing the degree to which dirt adheres to the surface. Obviously,
Since cleaning compositions typically include a surfactant whose primary purpose is to remove material from the surface, the selection of a soil release agent requires some care and the cleaning function of the composition is reduced. It is also important that the soil release agent be able to adhere in the presence of the surfactant while not being inhibited by the presence of the soil release agent.

[0004] Despite advances in this field, the extent to which dirt adheres to surfaces has been reduced and, in particular, electrolytes and / or
Alternatively, there is a need to provide a composition that provides formulation flexibility with respect to the cohesive potential of the composition in the presence of other minor components.

[0005]

It is believed that the present invention cleans the surface and deposits a layer of a cationic fluorosurfactant on the surface to facilitate subsequent removal of dirt deposited on the surface. It is to provide a stable composition.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention provides: (a) a cationic fluoro-surfactant;
An aqueous hard surface cleaning composition comprising a surfactant mixture comprising a non-fluorinated non-ionic surfactant.

The cationic fluorosurfactants present in the compositions of the present invention appear to modify the surface energy of the surface to which the composition has been applied, thereby increasing the contact angle of dirt subsequently deposited on the modified surface. It is.

[0008] Typical cleaning compositions within the scope of the present invention, besides nonionic surfactants, are effective in reducing the surface energy of surfaces cleaned with the composition to less than 25 mN / m. It also contains certain levels of cationic fluorosurfactants.

[0009]

DETAILED DESCRIPTION OF THE INVENTION For a better understanding of the invention,
The preferred components and details of the formulation are described in more detail below.

[0010] Fluoro surfactant composition of the present invention is essential to contain cationic fluoro surfactant. The presence of an effective amount of the fluorosurfactant is believed to deposit a "protective" layer on the surface to be cleaned. This layer prevents or reduces the adhesion of dirt subsequently applied to the surface. In addition, this layer gives a lower surface energy to the surface to be cleaned, and typically the compositions according to the invention reduce the surface energy to less than 25 mN / meter.

Suitable fluorosurfactant compounds can be broadly described as compounds containing at least one CF ₃ moiety and a group having a positive charge. Fluoro surface active agents containing CF ₃ group was discovered that the addition to the surface energy of the inhibitory effect greater than those containing only CF ₂ group.
