Problems solved by technology

This method solves the problems of sodium fatty acid decomposition, volatilization loss, and peculiar smell in high-tower spray-dried soap powder, but there is a big problem of poor solubility; the critical micelle temperature (critical solution temperature) of fatty acid sodium is higher than that of general Anionic surfactants, which have very low solubility at low temperatures, tend to float on water or adhere to clothing during washing, causing consumer complaints, and the active ingredient sodium fatty acid cannot fully play its role
Even if it is broken into very fine soap powder, it cannot be directly added in a very high amount. If 7% to 10% of sodium fatty acid is directly mixed into washing powder using soap powder raw materials, soap powder floating problems will occur during use, and Because the fine powder of high-content soap powder is expensive, the cost of producing laundry soap powder in this way is higher than the first method, so this method is not a very reasonable production method of laundry soap powder
[0005] The third method is to overcome the defects of the above two methods. Part of the 80% soap powder raw material in the second process is added to the slurry to dissolve, and a part is directly dry mixed into the washing powder after the ingredients. Although this method reduces The problem of floating during washing is solved, but the soap powder added to the slurry still has the problems of poor solubility, high slurry consistency, high production energy consumption, and peculiar smell during production
The production cost of such formula is also higher than process 1 and 2, and it is not the best production process

Embodiment 1

[0032] A sodium oleate soap powder composition is formed by mixing the following components:

[0033]

[0034] The preparation steps of this embodiment are as follows:

[0035] A batch of ingredients is 1 ton, pre-mix 10kg non-ionic AEO7 and 14kg oleic acid (1kg oleic acid can produce 1.08kg sodium oleate) into a uniform mixture, weigh 350kg of light sodium carbonate and 370kg of sodium sulfate Put it into a vertical double-screw dry mixing tank, start stirring, and stir for 1-2 minutes to make the mixture uniform, then slowly add the pre-mixed non-ionic AEO7 and oleic acid to the solid material with the stirring turned on, and react for 3 minutes , then add hydrogen peroxide solution and organic phosphonic acid, continue to stir for 5 minutes to 8 minutes, until all acidic materials are completely neutralized, pass through a 8 mesh to 10 mesh vibrating sieve, and remove large particles to obtain a finished product.

Embodiment 2

[0037] A sodium oleate soap powder composition is formed by mixing the following components:

[0038]

[0039] The preparation steps of this embodiment are as follows:

[0040]A batch of ingredients is 1 ton. 30kg of non-ionic AEO9 and 18.51kg of oleic acid (1kg of oleic acid can produce 1.08kg of sodium oleate) are pre-mixed into a uniform mixture, and 300kg of light sodium carbonate and 50kg of sodium metasilicate are weighed. , 100kg of sodium bicarbonate and 180kg of sodium chloride are placed in a vertical double-screw dry-mixing batching tank, and the stirring is turned on for 2 to 3 minutes to make the mixture uniform, and then the premixed non-ionic AEO9 Slowly add oleic acid to the solid material, react for 5 minutes, then add hydrogen peroxide solution and organic phosphonic acid, continue stirring for 5 minutes to 8 minutes, until all acidic materials are neutralized and reacted completely.

[0043]

[0044]

[0045] The preparation steps of this embodiment are as follows:

[0046] A batch of ingredients is 1 ton. 50kg of non-ionic AEO9 and 23.15kg of oleic acid (1kg of oleic acid can produce 1.08kg of sodium oleate) are pre-mixed into a uniform mixture, and 400kg of light sodium carbonate and 50kg of sodium metasilicate are weighed. Put 100kg of sodium bicarbonate and sodium bicarbonate into the vertical double-screw dry-mixing batching tank, start stirring, and stir for 2-3 minutes to make the mixture uniform, and then slowly add the pre-mixed non-ionic AEO9 and oleic acid under the state of stirring On the solid material, react for 5 minutes, then add hydrogen peroxide and organic phosphonic acid, continue to stir for 5 minutes to 8 minutes, until all acidic materials are neutralized and reacted completely. After passing through 8-10 mesh vibrating sieve, the la...

The sodium oleate soap powder composition is characterized by being uniformly mixed by the following components. The contents of the components is shown in the description. The sodium oleate soap powder composition and the production method thereof have simple production process, flexible formulation adjustment, no odor generation, low energy consumption and low cost.

Description

technical field [0001] 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 manufacturing method thereof. Background technique [0002] In recent years, laundry soap powder containing some fatty acid salts (soap base) has become more and more favored by consumers because of its natural, green, low foam, and easy to rinse. At present, China's light industry standard QB / T 2387-2008 laundry soap powder standard requires dry sodium soap (sodium fatty acid) content to be ≥7%. , containing 7% to 10% fatty acid sodium. At present, the production of soap powder is mostly produced in the following three ways: [0003] Fatty acid and liquid alkali sodium hydroxide are neutralized into fatty acid sodium, and common raw materials in washing powder include anionic surfactant (alkylbenzene sulfonate or alkenyl sulfonate), solid raw material soda ash, sodium sulfate, etc. to prepa...
