Abstract
The present invention relates to a storage stable liquid fabric softening composition comprising one or more fabric softener materials and a mixture of at least two cationic dye fixing agents, said composition providing an effective reduction of the amount of dyes released from coloured fabrics upon wet domestic treatments.
Description
Invention field
The present invention relates to stable liquid fabric softening composition, it has reduced in procedure for wet processing, for example the amount of the dyestuff that comes off from colored fabric in laundry operations.
Background of invention
The home treated of colored fabric is the known problem of laundry composition makers-up in the prior art.More particularly, being formulated in the procedure for wet processing problem that reduces by the laundry composition of the amount of the dyestuff that comes off on the colored fabric is the special challenge that the makers-up faces.Along with human consumer's trend is liked more bright-coloured clothes, this problem is more urgent at present.
Advised that in the prior art many methods are to address this problem, for example described in EP0341205, EP0033815, in washing process, handle fabric and use polyvinyl material or described in EP0462806, in rinse cycle, use above-mentioned substance as WO94/11482 described in the dye scavenging agent.
Yet though had these progress in the prior art, people still need effectively to reduce in procedure for wet processing the composition of the amount of the dyestuff that comes off from colored fabric.
In addition, a problem that is run in the art methods is that dye-fixing agent can be owing to contact destroys or damages in storage and/or washing process when being used for washing process, and when being used for rinse cycle, dye-fixing agent is used in combination and will makes the unstable mutually of product with fabric softener.Therefore, the applicant observes in fabric softener composition to be low to moderate 0.5% total content by weight and uses dye-fixing agent that the package stability of the composition that obtains is also produced unfavorable effect.This unstable is by weight, and the total content of dye-fixing agent is more obvious at least 3% the time.Because this product phase instability problem, the result has reduced the attractive in appearance of composition, for example the homogeneity of composition.
The applicant has now found that and uses the mixture of at least two kinds of cationic dyestuff fixing agents to satisfy this needs in the liquid fabric softening composition that contains one or more fabric softener materials.
The applicant also finds and uses a kind of dye-fixing agent opposite, when using this mixture in adding fabric sofetening composition, and the product that advantageously makes product prepare easily and obtain having good storage stability also.When described cationic dyestuff fixing agent has different solvabilities, when for example containing the mixture of at least a water-soluble cationic dye-fixing agent and at least a water-insoluble cationic dyestuff fixing agent, more preferably observe these effects.
Therefore, an advantage of the present invention is to provide fabric sofetening composition, and it provides and effectively reduce the dye quantity that comes off from colored fabric when the wet treatment of family.
Another advantage of the present invention is to provide the fabric sofetening composition with effective package stability.
Another advantage of the present invention is to provide the fabric sofetening composition with effective soft character.
Summary of the invention
The present invention relates to liquid fabric softening composition, it contains the mixture of one or more fabric softener materials and at least two kinds of cationic dyestuff fixing agents.In a preferred embodiment of the invention, the cationic dyestuff fixing agent has different water-soluble, promptly contains the mixture of at least a water-soluble cationic dye-fixing agent and at least a water-insoluble cationic dyestuff fixing agent.
According to a further aspect in the invention, it provides a kind of method of handling fabric.This method is included in that the water-bearing media of 50ppm liquid fabric softening composition of the present invention contacts with containing at least with fabric in the rinse cycle of human consumer's laundry processes.
The detailed description cationic dyestuff fixing agent of invention
A mixture that essential characteristic is at least two kinds of cationic dyestuff fixing agents of the present invention.Be the package stability of raising composition and the easness of composition preparation, dye-fixing agent preferentially is that structure is different, having different water-solublely thereby more preferably be that structure is different, is water miscible thereby more preferably make at least a dye-fixing agent, and at least a is water-insoluble." water-soluble cationic dye-fixing agent " is meant at room temperature and (15 ℃-25 ℃) contains by weight in water the composition of 1O% cationic dyestuff fixing agent is transparent." transparent " is meant the material that allows to see through the visible spectrum ray.Equally, " water-insoluble cationic dyestuff fixing agent " be meant at room temperature and (15 ℃-25 ℃) contain by weight in water the composition of 10% cationic dyestuff fixing agent is opaque, for example muddiness or shading.
Cationic dyestuff fixing agent or " fixing agent " they are known, commercial available material, and it improves the outward appearance of DYED FABRICS by the loss that reduces the dye for fabrics that causes owing to washing.
" positively charged ion " is meant the component based on various quaternized or organic nitrogen compounds that other is positively charged.
Being used for suitable cationic dyestuff fixing agent of the present invention is describing in " improving the aftertreatment of dyestuff firmness on the fabric fibre " among the Christopher C.Cook (REV.PROG.COLORATION, the 12nd volume, 1982).Be applicable to that preferred coloring agent fixing agent of the present invention is an ammonium compound, for example lipid acid-diamines condenses, for example oxidation products of the hydrochloride of oil base diethylamino buserelin, acetate, Methylsulfate and benzyl hydrochloride, oil base methyl-two quadrol Methylsulfate, single stearyl-Ya second diamino trimethyl ammonium Methylsulfate and tertiary amine; The derivative of polymerization alkyl diamine, polyamine-cyanuryl chloride condenses and amination glycerin dichlorohydrin.
In a preferred embodiment of the invention, in order to obtain better package stability, the dyestuff fixing agent composition preferably contains water-soluble and the water-insoluble dye-fixing agent.Yet although do not plan to be limited to theory, we believe for above-claimed cpd, water-soluble some factor affecting, for example number of molecular weight, cationic charge and/or counter ion of being subjected to.Therefore, the water-soluble or water-insoluble of considering to be used for each component of mixture will easily be determined according to above-mentioned condition by those of skill in the art.
Other water-soluble cationic dye-fixing agent is obtained by different suppliers with different trade names with water-insoluble cationic dyestuff fixing agent.The representative example of water-soluble cationic dye-fixing agent comprises: CROSCOLOR PMF that is obtained by Crosfield (in July, 1981, numbering № 7894) and CROSCOLOR NOFF (number № 8544 in January, 1988); SANDOFIX TPS, it can be obtained by Sandoz, this is to be used for preferred polycation fixing agent of the present invention, SANDOFIXSWE (resin cation (R.C.) compound), the Tinofix that is obtained by Ciba-Geigy (ECO and obtain REWIN DWR by CHT-Beitlich GMBH.
