Description

[Detailed description of the invention] The present invention relates to a detergent composition and a method for producing the same. In particular, the present invention provides granular detergent compositions and drying or granulation methods for producing these compositions.

In the manufacture of detergent compositions, a liquid containing one or more main components of the composition is used. The body composition (so-called detergent slurry) is made and then the slurry undergoes a drying process, generally It is customary to produce granular materials by subjecting them to a spray drying process. produce the final detergent composition. This granular base material is further processed in order to form a granular base material. For example, increasing the density and/or agglomerate and/or spray other active substances onto the powder; /or other powdered ingredients are mixed with the base powder.

In the manufacture of granular detergent compositions, the slurry to be dried is dried in conventional drying equipment. Preferably, the viscosity is low enough to allow the slurry to be inhaled and/or atomized. Yes. In order to obtain a satisfactory slurry viscosity, the It is customary for the slurry to contain a fairly large amount of water.

For example, US No. 4,261,793 (Procter and Gamble) Discloses a slurry containing 8% by weight or more water, GBB10189, No. 543 (Col.ga.te) is a detergent slurry containing about 29% by weight of water. - Disclose.

To reduce the costs associated with the drying process, reduce the moisture content of the slurry is preferable. This moisture reduction in the slurry provides particles with low porosity after drying. It is beneficial for When reducing the water content of slurries used in the production of granular detergent products The problem is that the viscosity of the slurry may increase.

To reduce costs associated with the drying process, the temperature at which the detergent slurry is preheated It is sometimes preferable to lower the However, traditionally, this preheating process and/or prevent crystallization of ingredients during slurry preparation and drying. It is considered necessary to stop

Inclusion of peptizing polymers in the slurry solves one or more of the above problems. the viscosity of the slurry can be beneficially reduced and/or the water content of the slurry can reduce the viscosity. can be reduced without problems and/or preheating of the slurry can be partially omitted.

Hydrophobic side chains or ionic groups are incorporated primarily in or on the outer bilayer of the droplet. This has the effect of reducing inter- or intra-droplet forces, i.e. Forces between individual surfactant molecules in adjacent layers within a droplet and surfactant content of adjacent droplets The difference between the forces between droplets increases and the forces between adjacent droplets are reduced. This is generally , the smaller the force between the droplets, the greater the distance between adjacent droplets, resulting in a reduction in viscosity. Jiru.
