Description
Technical Field
The invention belongs to the technical field of effervescent detergents, and particularly relates to an effervescent washing product with high storage stability 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 common disintegrant, also the most effective disintegrant today, is an effervescent system of an acid-base reaction. For example CN1354780A discloses an effervescent component comprising an acid source and a carbon dioxide source (base). However, in such an acid-base reaction effervescent system, an acid source and an alkali source are in direct contact with each other, and both of them easily react during storage, resulting in poor storage stability. Particularly, the reaction is easier to occur in a humid environment, and water generated after the acid-base neutralization reaction is absorbed by other hair components to form crystalline hydrate, so that the effervescent system is ineffective.
On the other hand, in order to ensure the dissolution rate of the detergent bar in use, the components are substantially powdery anhydrous components. Since the powdery anhydrous substance has no stickiness, the obtained detergent cake is easily dispersed by an external force. One of the solutions is to use higher pressure for tabletting, but the higher the pressure used, the poorer the disintegration property of the prepared block detergent; another way is to use a binder, such as the tea stain cleaning effervescent tablet disclosed in CN103966029A and its preparation method, wherein the formulation comprises an oxidative bleaching agent, an acidic disintegrating agent, an alkaline disintegrating agent, a binder and a surfactant. With the addition of the binder, the required compression pressure is reduced. Common binders include polyethylene glycol, polyvinylpyrrolidone, cellulose, and the like. The binder is typically sprayed onto the surface of the detergent powder in a molten or molten state during compounding prior to tableting. Although the binder can solve the problem of low mechanical strength of the detergent block, it increases the raw material cost of the detergent block, and the conventional binder is a substance having no washing-related functional activity during the washing process, and may adversely affect the washing effect.
Disclosure of Invention
The invention aims to provide an effervescent washing product with high storage stability, which has simple components, can still keep the effectiveness of an effervescent system after long-term storage, has high dissolution speed during use and can well meet the use requirements of the effervescent washing product.
The second object of the present invention is to provide a process for preparing the effervescent detergent with high storage stability.
The first purpose of the invention is realized by the following technical scheme:
an effervescent detergent with high storage stability comprises acidic anionic surfactant, organic acid complex, sodium carbonate and sodium bicarbonate;
the organic acid complex consists of an organic acid A and an organic acid B, wherein the organic acid A is a water-soluble anhydrous organic acid, and the organic acid B is an organic acid which is difficult to dissolve in water;
and the organic acid complex is prepared by the following method:
and mixing the organic acid A and the organic acid B, heating to a molten state under the stirring condition, and cooling by a concurrent spray cooling method to obtain the organic acid complex.
The organic acid A is polycarboxylic acid and is selected from one or more of citric acid, tartaric acid and malic acid; the organic acid B is selected from a single organic acid or a mixture of a plurality of organic acids with the melting point of more than 40 ℃ and the boiling point of more than 180 ℃ under normal pressure, and preferably comprises one or more of lauric acid, myristic acid, palmitic acid and stearic acid.
The organic acid complex of the invention is the key to maintaining the effectiveness of an effervescent system: the organic acid A is an organic acid which is easy to dissolve in water, and the organic acid B is an organic acid which is difficult to dissolve in water. And after the organic acid A and the organic acid B are mixed and melted, re-granulating in the process of cooling by a concurrent spray cooling method, so that the obtained organic acid complex is not a simple mixture. Two types of organic acids recrystallize, changing in intermolecular structure and crystal morphology:
the melting point of the organic acid A is relatively high, and the organic acid A is crystallized before the organic acid B in the cooling process. Thus, the organic acid A becomes a crystal nucleus of the organic acid complex; and the relative melting point of the organic acid B is lower, the crystallization speed is slow in the cooling process, and a crystal shell is more prone to be formed.
The organic acid A is polycarboxylic acid, has large steric hindrance, and has a carbon chain inside and a carboxyl outside in the spatial structure. After the organic acid A forms a crystal nucleus, the hydrogen atom on the carboxyl group of the organic acid A is in an electron-deficient state, and the electron-rich carbonyl oxygen on the carboxyl group of the organic acid B is attracted, so that the carboxyl group faces inwards and the carbon chain faces outwards when the organic acid B forms a crystal shell. As a result, the outermost edges of the crystal shells are all organic carbon chains after the crystals are formed, thereby increasing the hydrophobicity of the organic acid complex. Therefore, even if the effervescent tablet is placed in a humid environment, the organic acid complex has low probability of being wetted and is not easy to react with alkali in the effervescent detergent, so that the stability of an acid-base reaction effervescent system is maintained.
In the using process, after the effervescent washing article is put into water, sodium carbonate and sodium bicarbonate in the effervescent washing article are dissolved, the alkalinity is increased, the crystal structure in the organic acid complex is broken down, the acid-base reaction is rapidly carried out, the effervescent effect is generated, and the detergent which is originally in a sheet shape is rapidly dissolved. In the reaction process, the organic acid B can form fatty acid soap, can effectively inhibit excessive foam generated in the effervescence process, and achieves the effect of easy rinsing when washing clothes; when used in bathing, gives a more refreshing feeling to the skin.
As an embodiment of the invention, the effervescent washing product with high storage stability comprises the following components in percentage by mass:
8-15% of acidic anionic surfactant
30 to 40 percent of organic acid complex
20 to 35 percent of sodium carbonate
10-20% of sodium bicarbonate.
In a preferred embodiment of the present invention, the organic acid complex contains 5 to 10% by mass of the organic acid B based on the mass of the organic acid a.
In the preparation process of the organic acid complex, the heating temperature depends on the specific types of the organic acid A and the organic acid B, which are specifically selected, as long as the organic acid A and the organic acid B are all in a molten state, and generally does not exceed 175 ℃.
The particle size of the organic acid complex is preferably 60-180 meshes, and more preferably 80-120 meshes.
The acidic anionic surfactant in the effervescent washing product can play a role of a binder, and under the condition, the effervescent washing product has good mechanical property without adding a traditional binder. And after the effervescent washing product is put into water, the acid anionic surfactant can react with sodium carbonate and quickly dissolve in the water, and the dissolution speed is faster than that of a physical dissolution process, so that the effervescent washing product is quickly dissolved. The acidic anionic surfactant is selected from linear alkyl benzene sulfonic acid and/or fatty alcohol polyoxyethylene ether carboxylic acid.
In the cooling process of the concurrent spray cooling method, the temperature of an air inlet of the spray tower is 150-180 ℃, and the temperature of an air outlet is not higher than 55 ℃.
The effervescent washing product can be added with other components beneficial to a detergent according to actual use requirements, and comprises 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, polyacrylate, a release agent and a defoaming agent. The addition amount of the detergent can be added according to the use requirement of common washing products.

And (3) the pressure in the sheet pressing process in the step (2) is 60-150 kN.
