There is provided a process for preparing a liquid softening composition comprising a fabric softener, a nonionic alkoxylated stabilising agent, and a dye component, whereby the resulting softening composition exhibits effective freeze-thaw recovery properties and good dye homogeneity.

Description

The method for preparing liquid fabric softening composition
Invention field
The present invention relates to have the preparation method of the soft compound that contains dyestuff that effectively freezes molten recovery properties
Background of invention
The fabric sofetening product is known in the prior art, is used for providing effective soft effect to handled fabric.Yet existing problem is at low temperatures, and promptly product freezes when 0 ℃ of following temperature is stored, and causes product can not return to the homogeneous dispersion with acceptable flowability matter when being placed on comparatively high temps following time.
Therefore, the purpose of this invention is to provide to have and effectively freeze the molten fabric sofetening product that recovers.
Satisfy a kind of solution of these needs and describe in GB-1098793, it uses the vitriol of aliphatic amide in fabric sofetening composition.
Another solution is described in EP-A-0507478, and it provides mixes cationic fabric softener and melt with nonionic stabiliser, subsequently it is dispersed in the water.Yet the existing problem of this method is to need processing unit, high-shear mixer for example, thus increased preparation cost.
Therefore, another purpose of the present invention provides only needs the fabric sofetening of minimum processing unit product.
It is found that and not use high-shear in the fabric sofetening product processing, the formation of dyestuff color spot increases, and uses high-shear, has avoided forming in the fabric sofetening product not dispersive dye granule.
Therefore, the makers-up of soft compound has good dyestuff homogeneity in the face of preparation, and does not need the double challenge of the soft compound of high shear mixing equipment.
The applicant finds that now adding dye component with the nonionic alkoxy-based surface-active agent in final cold flexible products has satisfied this needs.
In fact, can dyestuff and the oxyalkylated tensio-active agent of nonionic be added in the cold the finished product by simple the mixing.The composition that is obtained obtains uniform dispersion.
The invention has the advantages that the fabric sofetening product of the dilute form by the inventive method preparation with by mixed goods softening agent and nonionogenic tenside, in water, disperse the product of preparation to compare subsequently and need less mechanical shearing.Although do not want to be limited to theory, we think that nonionogenic tenside makes dyestuff become micella, form mictocystis with the softening agent active substance subsequently.Dyestuff disperses effectively by this way, and product obtains the good molten recovery properties of freezing.
Summary of the invention
The present invention relates to prepare the method for liquid fabric softening composition, it comprises the steps:
A)-mix and heating fabric softener and selective additives to form melts;
B)-melts is dispersed in the water;
C)-before adding dyestuff and nonionic alkoxylate stablizer, the dispersion that obtains is cooled under the Krafft temperature of softening agent active substance.
On the other hand, present invention resides in the purposes that molten restorative is frozen in the conduct of nonionic alkoxylate stablizer in the liquid fabric softening composition.
