According to the present invention, this method has been showed the fluidization effect by neutralizing agent, makes the acid parent of its dry neutralize anionic surfactant, and preferably this method is carried out in fluidized-bed.Dry neutralisation be meant a neutralization part at least and preferably basically in and all acid sexupara body, mixture still keeps the particulate state simultaneously.The suitably adding of the acid parent of control is not accumulated in the detergent composition it with neutral condition not.
Suitable neutralizing agent is granuliform, and contains alkaline inorganic material, preferably contains basic salt.Suitable material comprises alkaline carbonate and supercarbonate, for example their sodium salt.
The suitable consumption of neutralizing agent with enough fully neutralizing acid sexupara body be as the criterion.If desired, can use neutralizing agent, to guarantee to neutralize fully or provide another kind of effect, for example in the clean effect of using under the yellow soda ash situation that increases above stoichiometric quantity.
Except anion surfactant by the neutralisation preparation, can add other anion surfactants in due course, or nonionic, positively charged ion, zwitter-ion, both sexes or semi-polarity tensio-active agent and composition thereof.Suitable tensio-active agent comprises those tensio-active agents of Schwarz and Perry general introduction in " tensio-active agent and washing composition " the 1st volume.Therefore, if desired, with containing C
12-C
15The soap saturated or that unsaturated fatty acids is produced of carbon atom also can be used as anion surfactant to be used.
The suitable consumption of detergent surfactant is the 5-40% (weight) of detergent composition, is preferably 12-30%.
Detergent composition is fit to contain detergent builder compound.Washing assistant can add simultaneously with neutralizing agent as required and/or add after adding neutralizing agent.Preferably washing assistant and neutralizing agent are added simultaneously.
Can use arbitrary washing assistant commonly used, suitable washing assistant comprises the calcite of yellow soda ash, zeolite, tripoly phosphate sodium STPP (STPP), Trisodium Citrate and/or high surface area.Washing assistant also can mix by individually a kind of in the above-mentioned washing assistant or with other washing assistant and form.
Washing assistant and neutralizing agent can be commaterials, yellow soda ash for example, and in this case, the quantity of material of use should enough play this two kinds of effects.
The suitable consumption of washing assistant is the 15-65% (weight) of detergent composition, and is preferably 15-50%.
Detergent powder prepared in accordance with the present invention has suitably low bulk density, is 350-650g/l or 450-650g/l, and is for example, about 500g/l, therefore equally matched with the bulk density that utilizes spray-drying process to obtain.
With a kind of optional adding in the composition with preferred flow promotor.Can before or after adding part or all acid parent, flow promotor be mixed with neutralizing agent and washing assistant (if the work that has).Before or after adding a part of acid parent, add flow promotor, thereby the bulk density of product powder is obviously descended.
The suitable consumption of flow promotor is the 0.1-15% (weight) of detergent composition, and preferred consumption is 0.5-5%.
Suitable flow promotor comprises crystalline form or amorphous alkali metal silicate, calcite, diatomite, silicon-dioxide, for example sedimentary silicon-dioxide, sal epsom and lime carbonate, for example sedimentary lime carbonate.Can adopt these mixtures of material as required.In preferred embodiments, flow promotor is Dicamol.
