Description

Effervescent washing product with high disintegration speed and easy rinsing and preparation method thereof
Technical Field
The invention belongs to the technical field of effervescent detergents, and particularly relates to an effervescent detergent with high disintegration speed and easy rinsing and a preparation method thereof.
Background
A block-shaped washing article is a quantitative washing article, namely the mass of each washing article is constant. The washing product is convenient to measure, and when the washing product is used by a consumer, the use amount of the washing product can be accurately controlled only by putting a corresponding amount of block-shaped washing products according to the actual use requirement. On the other hand, the block-shaped washing article does not contain water, and the content of active components can be higher than that of the liquid-state washing article, so that the block-shaped washing article is more convenient to transport and store.
The detergent bar needs to dissolve rapidly during use. In order to ensure the dissolution rate, a method commonly used in the prior art is to add a disintegrant.
One common disintegrant includes rapidly swellable polymers, or polyvinylpyrrolidone, modified cellulose, etc., but rapidly swellable polymers are prone to failure after long term storage, and polyvinylpyrrolidone and modified cellulose have a very limited degree of improvement in disintegration rate.
Another currently most common and most effective disintegrant is the effervescent system of an acid-base reaction. For example, CN1354780A discloses an effervescent component, and an acid-base reaction effervescent system is used. In the technical scheme, in addition to the acid source and the carbon dioxide source, in order to make the acid source into a granular state, the exterior of the acid source is coated with a coating. Generally, the coating of the effervescent component uses materials with high HLB value, and usually has nonionic surfactant or nonionic emulsifier, especially nonionic emulsifier.
However, these nonionic emulsifiers do not have a detergency effect, and may cause some hindrance to the detergent ingredients and may affect the detergent effect during use. On the other hand, the effervescent system can play an effervescent role after the acid source and the carbon dioxide source which are wrapped contact, and the dissolution speed of the solid nonionic surfactant or the nonionic emulsifier is low, so that the time consumed for releasing the acid source and the carbon dioxide source is long, and the effervescent washing product can play a role after being put into water for a period of time, and is inconvenient to use. In addition, as the common nonionic surfactant and the nonionic emulsifier are inert substances and do not react with other components in the system, the dissolution speed of the effervescent washing product added into water is further slowed down.
Furthermore, nonionic surfactants and nonionic emulsifiers are relatively difficult to rinse and require multiple rinses after use of the effervescent detergent.
Disclosure of Invention
The first purpose of the invention is to provide an effervescent washing product which has high disintegration speed and is easy to rinse, has high dissolution speed, is easy to rinse, and can meet the application occasions of various washing products.
The second purpose of the invention is to provide a preparation method of the effervescent washing article with high disintegration speed and easy rinsing.
The first purpose of the invention is realized by the following technical scheme:
an effervescent washing product with high disintegration speed and easy rinsing comprises an acidic anionic surfactant, water-soluble solid anhydrous organic acid, solid fatty acid, sodium carbonate and sodium bicarbonate; the sodium carbonate adsorbs acidic anionic surfactant to form particles, and the solid fatty acid coats the sodium bicarbonate to form the particles.
The sodium carbonate and the sodium bicarbonate which are used as alkali sources (carbon dioxide sources) in the components are in a coated particle state. Wherein the sodium carbonate is encapsulated by an acidic anionic surfactant and the sodium bicarbonate is encapsulated by a solid fatty acid. The solid fatty acid can be used for coating sodium bicarbonate to replace conventional nonionic surfactant or nonionic emulsifier. The fatty acid salt formed by neutralizing the fatty acid is a surfactant, and plays a positive role in improving the detergency in the washing process. Another benefit of using solid fatty acids is: the fatty acid is easy to wash, and the effervescent washing product can be conveniently rinsed after washing; when used in personal cleansing products, the flush skin feel is very fresh.
The fatty acid used as the coating and the sodium bicarbonate used as the coated coating in the formulation of the present invention do not react under normal storage conditions. After the washing article is thrown into a large amount of water, the sodium carbonate is dissolved firstly, so that the whole water solution is alkaline. The alkaline aqueous solution and the fatty acid have acid-base reaction, so that the fatty acid is quickly dissolved, sodium bicarbonate wrapped in the fatty acid is released, and the alkaline aqueous solution reacts with the dissolved water-soluble anhydrous organic acid, and the phenomenon of violent effervescence occurs.
As a preferable embodiment of the invention, the effervescent washing article comprises the following components in percentage by mass:
8-15% of an acidic anionic surfactant;
30-40% of water-soluble solid anhydrous organic acid;
3-5% of solid fatty acid;
20-35% of sodium carbonate;
10-20% of sodium bicarbonate.
For better effect of the present invention, the solid fatty acid is one or more organic fatty acids with melting point higher than 40 ℃ and boiling point higher than 180 ℃ under normal pressure, including but not limited to one or more of lauric acid, myristic acid, palmitic acid and stearic acid.
In one embodiment of the present invention, the acidic anionic surfactant is linear alkylbenzene sulfonic acid and/or fatty alcohol polyoxyethylene ether carboxylic acid.
The water-soluble solid anhydrous organic acid is water-soluble organic acid which is in a solid state at normal temperature and normal pressure and has no crystal water. The water-soluble solid anhydrous organic acid is one or more selected from citric acid, tartaric acid, maleic acid and malic acid.
The effervescent washing product can also comprise various common components in the existing washing product, including one or more of solid polymer builder, layered sodium silicate, carbon peroxide, 4A zeolite, solid fatty alcohol sodium sulfate, powdery alpha-alkenyl sodium sulfonate, an enzyme preparation, bentonite, essence, fatty alcohol-polyoxyethylene ether, fatty acid methyl ester sodium sulfonate, sodium citrate, a defoaming agent, a release agent and sodium polyacrylate. The addition amount of the detergent can be added according to the use requirement of common washing products.
The second purpose of the invention is realized by the following technical scheme:
a preparation method of an effervescent washing product with high disintegration speed and easy rinsing comprises the following steps:
(1) preparing sodium bicarbonate particles, namely heating solid fatty acid to a molten state, uniformly spraying the solid fatty acid on the surface of sodium bicarbonate, then agglomerating and molding in a fluidized bed, and screening particles with the particle size of 60-180 meshes to obtain sodium bicarbonate particles;
(2) the preparation method of the sodium carbonate particles comprises the steps of mixing an acidic anionic surfactant with sodium carbonate, enabling the acidic anionic surfactant to be completely adsorbed by the sodium carbonate, and screening out particles with the particle size of 60-180 meshes to obtain the sodium carbonate particles;
(3) and (3) mixing the sodium bicarbonate particles prepared in the step (1), the sodium carbonate particles prepared in the step (2) and the water-soluble solid anhydrous organic acid uniformly, and tabletting by using a tabletting machine to obtain the effervescent washing product which is high in disintegration speed and easy to rinse.

TABLE-1
Figure BDA0002360549420000051
Figure BDA0002360549420000061
The results in the table show that, compared with the comparative product, the disintegration time of examples 1 to 8 is shorter than that of the comparative product, and the results prove that the disintegration speed of the effervescent detergent is positively influenced by the acidic anionic surfactant coated sodium carbonate forming particles and the solid fatty acid coated sodium bicarbonate forming particles, and the influence is more obvious after strengthening treatment.
In the rinsing performance test, the height of the foam of examples 1 to 8 after the third rinsing was 0mm, which indicates that the effervescent detergent of the present invention was rinsed clean after 3 times of rinsing.
The effect of the particle size of the sodium bicarbonate particles obtained in step (1) and the sodium carbonate particles obtained in step (2) on the effervescence speed was tested and the results are shown in table-2 below, in which the data represent the disintegration time(s):
TABLE-2
Figure BDA0002360549420000071
Figure BDA0002360549420000081
As can be seen by comparing the results of the above table-1 and the above table-2, when the particle diameters of the sodium bicarbonate particles and the sodium carbonate particles are 60-180 meshes, the disintegration time is superior to that of the comparative product in the table-1; the particle size of the sodium bicarbonate particles and the sodium carbonate particles is 80-120 meshes, and the disintegration time is shorter.
Comparative examples 1 to 8
Compared with the corresponding examples, the following respective proportions are that an acid source (water-soluble solid anhydrous organic acid) and an alkali source (sodium carbonate and sodium bicarbonate) are kept unchanged, an alkoxylated alcohol with a melting point of 40-70 ℃ is used for replacing fatty acid, the acid anionic surfactant is replaced by an anionic surfactant which becomes a salt after neutralization, the acid source or the alkali source (sodium bicarbonate) is wrapped by the alkoxylated alcohol, and then tabletting is carried out.
