Description
Technical Field
The invention relates to the field of detergent compositions mainly using soap as a base material, in particular to a sodium oleate soap powder composition and a preparation method thereof.
Background
In recent years, laundry soap powders containing partial fatty acid salts (soap bases) are becoming more and more popular among consumers due to their natural, green, low-foaming, easy rinsing, and other characteristics. In the current standard of China light industry QB/T2387-2008 laundry soap powder, the content of dry sodium soap (fatty acid sodium) is required to be more than or equal to 7%, most of the currently marketed laundry soap powder executes the light industry standard QB/T2387-2008 and contains 7% -10% of fatty acid sodium. At present, soap powder is produced by adopting the following three modes:
the fatty acid and liquid alkali sodium hydroxide are neutralized into sodium fatty acid, and the common raw materials in the washing powder comprise anionic surfactant (alkyl benzene sulfonate or alkenyl sulfonate), solid raw material soda, anhydrous sodium sulphate and the like to prepare slurry with total solid of 60-70%, and then the slurry is sprayed and dried by a high tower to prepare the washing soap powder. In general, the temperature of hot air in the high tower spray drying process is above 300 ℃, and the fatty acid sodium is decomposed at high temperature to generate unpleasant smell. Because of the environmental protection problem, the peculiar smell gas is not allowed to be discharged in most areas at present, so the production of the laundry soap powder is limited; in addition, because the viscosity of the slurry added with the sodium aliphatate is higher than that of the slurry of the common washing powder, the total solid of the slurry for producing the soap powder is lower than that of the slurry of the common washing powder, and the heat energy consumption required during spray drying is higher; still another biggest problem is that the sodium aliphatate is decomposed at high temperature, so that part of the sodium aliphatate is lost due to decomposition and volatilization, and great waste is caused. Therefore, the production of laundry soap powder by the high tower spray drying process should be gradually eliminated in the future.
The second production mode is that firstly, the grease and the liquid alkali are used for saponification reaction to produce high-content soap base, then the high-content soap base is dried and crushed into soap powder with the content of more than 80%, and more than 80% of soap powder raw materials are directly mixed with washing powder to prepare the washing soap powder. The method solves the problems of decomposition, volatilization loss and generation of peculiar smell of the sodium aliphatate in the high-tower spray-dried soap powder, but has a great problem of poor solubility; the critical micelle temperature (critical solution temperature) of the sodium fatty acid is higher than that of a common anionic surfactant, the solubility of the sodium fatty acid is very low at low temperature, the sodium fatty acid is easy to float on water surface or adhere to clothes during washing, consumer complaints are caused, and the active ingredient sodium fatty acid can not play a role completely. Even if the soap powder is smashed into very fine soap powder, the addition amount of the soap powder cannot be very high directly, if 7-10% of sodium fatty acid is directly mixed into the washing powder by using the soap powder raw material, the problem of floating of the soap powder can be caused during use, and the cost for producing the washing soap powder by the method is higher than that of the first method because the price of the high-content soap powder and the fine powder is high, so the method is not a very reasonable production method of the washing soap powder.
The third method is to overcome the defects of the two methods, and part of the soap powder raw material with the content of 80 percent in the second process is added into the slurry to be dissolved, and part of the soap powder raw material is directly mixed into the washing powder in a dry mode after the auxiliary materials are added, so that the method reduces the floating problem during washing, but still has the problems of poor soap powder solubility, high slurry consistency, high production energy consumption and peculiar smell during production. Such formulations are also more expensive to produce than processes 1 and 2, and are not optimal production processes.

sodium aluminosilicate, i.e., zeolite 4A;
the organic phosphonate is selected from at least one of hydroxyl ethylidene diphosphonate, nitrilo trimethylene triphosphonate and ethylene diamine tetramethylene phosphonate, and is generated by the reaction of organic phosphonic acid and solid alkaline materials;
the decolorizing agent is hydrogen peroxide solution with the mass percent concentration of 15-50%, and the decolorizing agent reacts with solid alkaline materials to generate peroxide, and 30% of hydrogen peroxide is preferred in view of the easy availability and safety of raw materials. If the used oleic acid is light in color and the neutralized product is white in color, a decolorizing agent can not be added;
the solid filler is anhydrous sodium sulphate or sodium chloride.
The preparation method of the sodium oleate soap powder composition is characterized by comprising the following steps: the method is implemented in sequence according to the following steps:
the oleic acid and the nonionic surfactant are uniformly premixed in a premixing tank, if the oleic acid and the nonionic surfactant are solidified at a low temperature, the oleic acid and the nonionic surfactant are heated and melted into transparent liquid for use before use, and the heating temperature is not more than 50 ℃;
adding a solid alkaline material and a solid filler into a vertical double-helix dry mixing tank, and stirring for 1-3 min to mix uniformly;
the vertical double-helix dry mixing tank is always kept in a stirring and opening state, and the mixture of liquid oleic acid and nonionic surfactant is directly added into the vertical double-helix dry mixing tank to react for 5min +/-1 min; then adding organic phosphonic acid, and continuing stirring for 5-8 min until all acidic components are completely neutralized and react, and the appearance is in a white flowable powder state; adding sodium aluminosilicate, stirring and mixing uniformly;
and (3) inputting the white product in a flowable powder state into a 5-8-mesh vibrating screen through a discharge port of a vertical double-helix dry mixing tank, and sieving to remove large particles, wherein the rest is the sodium oleate soap powder composition.
