Description

The cleaning combination that comprises the immiscible fluid system
Technical field
The present invention relates to a kind of cleaning/cleaning composition, and relate to of the improvement of this cleaning/cleaning composition of application the method or the technology of cleaning/washing.Specifically, this cleaning/cleaning composition is a transport property of being devoted to provide by the immiscible fluid with high interfacial tension the enhancement of accelerant.
Background of invention and prior art
Usually, fabric is that water and a kind of detergent surfactant system are cleaned, and this is called as and washes.Tensio-active agent is attracted to fabric and dirt on the two and therefore reduced interfacial energy separately, so just feasiblely removes dirt from fabric and becomes easy.Alternatively, also can be with the method for so-called dry-cleaning, wherein used organic solvent such as tetrachloroethylene (PCE), based on the solvent of oil or be called Stoddard's solvent, chlorofluorocarbon CFC-113 and 1,1,1-trichloroethane etc., all these solvents generally all are aided with tensio-active agent.These organic solvents can help to remove oily dirt under the condition that washing composition exists.Removing of dirt can be reached by reducing interfacial tension in a small amount, the big portion of particulate state dirt can be removed by stirring is provided.
The efficient of having known fabric cleaning composition can be enhanced by add some accelerants in prescription, and these accelerants have such as fabric softener, white dyes, dye transfer inhibitor, white dyes etc.Yet, when these accelerants and surfactant system are formulated together, can throw into question, for example, fabric softener generally is a cationic, when with prescription in the anionic detergent actives can cause unstable in the storage process when combining.Also have, when the nonionic surfactant of they and ethoxyquin in conjunction with the time also can cause the viscosity aspect problem of prescription, and this problem is more obvious when temperature is higher than 37 ℃.
US-A-3,640,881 (Hoechst Celanese Corp.) disclose and have contained a kind of wetting ability white dyes and the compsition for dry washing of coordinate detergent materials mutually with it, can be used to clean simultaneously and the brightened goods structure, particularly contain the white clothes of suitable content regenerated fiber.This technology partly is based on such discovery, the white dyes that promptly can be scattered in common organic dry-cleaning system in the water can play the effect of brightness regenerated when having a small amount of moisture content to exist, prevent that woven fabric structure from shading, fade, turn to be yellow or obtaining other undesirable character when dry-cleaning.Use detergent materials, particularly amphoteric detergent materials, promoting upward, light effect is very important.
We are early reporting and in the common pending application WO-A-01/90474 of issue on November 29 calendar year 2001, a kind of method of cleaning fabrics is disclosed, wherein used the liquid-liquid interface of at least two kinds of unmixing liquid phases under agitation, its interfacial tension is greater than 5mN/m.Wherein verified, under the condition that does not have other detergent active and accelerant to exist, this immiscible system can be reached effective cleanup action.
The organic solvent that is used to clean generally is deleterious, and can cause other problem, so for example they are the flammable potential fires that cause.Be solvent vapour loss and escape into tendency in the atmosphere in the cleaning system to the main concern of solvent cleaning in addition, particularly when they use at elevated temperatures.Solvent cleaning technology is generally used the chlorating solvent, and the minimizing of this and ozonosphere is relevant.Having carried out some attempts avoiding these problems and seeks suitable surrogate.
No matter used type of solvent, promptly no matter they are water or organic solvent, for quickening to remove soluble soil or insoluble particulate state dirt, it is very important in cleaning medium clothes being stirred.In the dry-cleaning process, when using tensio-active agent, also can use about 10% water at most together simultaneously, so that removing of water-soluble spot becomes easy with solvent systems.
The common pending application application 999/MUM/2001 that we submitted in October 12 calendar year 2001, lecture the immiscible liquid phase of a kind of usefulness and come method of cleaning fabrics, the carbon chain lengths of wherein less polar solvent is greater than 6, and/or be the siloxanes that contains more than 3 SiO units, be used for preventing the problem of toxicity, combustibility and environmental protection aspect, kept good cleanup action simultaneously fabric.
General introduction of the present invention
Have now found that, be used for cleaning/efficient of the accelerant of washing system, can be improved greater than the immiscible fluid system of 5mN/m by using its interfacial tension, and can not meet those problems when using the conventional surfactants system, the carbon chain lengths of less polar solvent is at least 4 in this immiscible fluid system, perhaps also can be with the siloxanes that contains more than 3 SiO units.
