Description

Washing gel bead with 8 times of cleaning power and preparation method thereof

Technical Field

The invention relates to the technical field of daily chemical detergents, in particular to a washing gel bead with 8 times of cleanliness and a preparation method thereof.

Background

Concentrated detergents are the key development and encouragement in the chinese laundry industry program, and it is proposed that by 2020 concentrated liquid detergents should achieve a 20% target of total liquid detergent weight. Moreover, the "regulations on the implementation of tax Law for environmental protection" officially executed 1/2018 also encourages the industry to focus on the subject of industrial concentration. Under the push of policy and consumer market, the laundry detergent concentration is out of the way.

Chinese patent No.: 201710091551.7 discloses a low-foam easy-rinsing washing gel bead and a preparation method and application thereof, comprising 15-30% of C12-C18 alkyl glucoside, 15-25% of coconut oil fatty acid diethanolamide, 10-20% of surfactant Besmann LT107, 10-20% of Besmann L85, and components such as polyalcohol, enzyme, essence, preservative, deionized water and the like. The surfactant adopted by the washing gel bead product is a green product, can be completely degraded, has low residue and good decontamination performance; the Besmann surfactant composition contained in the formula has the characteristic of easy rinsing, and can save a large amount of water.

The washing gel bead product has the highest active content, can achieve the cleaning effect which is 6 times higher than that of the common washing liquid at most under the same using amount, and the washing gel beads which are declared to have the 8 times of cleaning effect on the market at present are mostly added with protease, so that only the cleaning power to national standard protein stains is realized. To achieve 8 times the cleaning effect on national standard carbon black, protein and sebum stains, an ultra-highly concentrated formula is required, but the solubility of a common surfactant, such as sodium dodecyl benzene sulfonate, is limited, so that the addition amount is not too high; for example, the surfactant fatty alcohol polyoxyethylene ether sodium sulfate has the water content of over 30 percent in the commercial product, and if the addition amount is too large, the washing bead envelope polyvinyl alcohol is dissolved and broken. In addition, if the active content is too high, the problems of unstable formula, material precipitation and the like are caused, and if the active content is too low, the effect of 8 times of cleaning power cannot be achieved.

Disclosure of Invention

Therefore, aiming at the above content, the invention provides a washing gel bead with 8 times of cleanliness and a preparation method thereof, and solves the problem that the formula of the washing gel bead in the prior art can only have 8 times of cleaning effect on certain stains in carbon black, protein and sebum stains, and can not achieve 8 times of cleanliness on all the three stains.

In order to achieve the purpose, the invention is realized by the following technical scheme:

a laundry bead with 8 times of cleanliness comprises the following components in percentage by mass:

the further improvement is that: the solubilizer is formed by mixing any one or more than two of propylene glycol, glycerol and sorbitol in any ratio.

The further improvement is that: the isomeric alcohol ether is Bassfu Lutensol XL-80.

The further improvement is that: the anti-redeposition agent is Acusol 845 hydrophobically modified acrylic polymer or Unicap K25A styrene-acrylic hydrophobically modified copolymer.

The further improvement is that: the protease is Novoverest Progress Uno100L or Pasteur Lavergy Pro 104 LS.

The further improvement is that: the trisodium N, N-dicarboxymethylalanine is Acksonobel Dissolvine M-40.

A preparation method of a laundry bead with 8 times of cleanliness comprises the following steps:

(1) weighing the raw materials according to the mass percentage;

(2) adding a solubilizer into a reaction kettle, heating to 55-65 ℃, then adding dodecylbenzene sulfonic acid, slowly adding triethanolamine for neutralization, uniformly mixing, and then adding sodium fatty alcohol-polyoxyethylene ether sulfate; adding fatty acid methyl ester ethoxylate, isomeric alcohol ether and AEO-9 after completely dissolving, stirring for 20-40min, adding N, N-dicarboxymethylalanine trisodium and anti-redeposition agent, stirring until completely dissolving, cooling to room temperature, adding protease, kasong, DMDM hydantoin and daily essence, stirring uniformly, and adjusting pH value to 7.0-8.0 to obtain a washing gel bead liquid;

(3) and (3) feeding the washing gel bead liquid into an automatic packaging machine, and packaging the washing gel bead liquid by using a PVA water-soluble film to prepare the washing gel bead with 8 times of cleanliness.

By adopting the technical scheme, the invention has the beneficial effects that:

the selected surfactants are surfactants with high active matter content and low water content, for example, the active matter content of fatty acid methyl ester ethoxylate is up to more than 95%, and the active matter content of fatty alcohol polyoxyethylene ether AEO-9 and basf XL80 isomeric alcohol ether is up to more than 99%. Compared with the traditional polyether surfactant, the fatty acid methyl ester ethoxylate has low foam and high cloud point, and can be quickly dissolved in cold water. The improvement of the concentration of the surfactant can influence the fluidity and the stability of the product, the product can generate a gel phenomenon when dispersed in water, the isomeric alcohol ether has a good inhibition effect on the gel phenomenon, the heat resistance and the cold resistance are excellent, and the product can be quickly dissolved in water, so that a formula system is more stable.

The fatty alcohol-polyoxyethylene ether AEO-9 has high active matter content, many fatty alcohol-polyoxyethylene ethers are in semitransparent jelly shape at room temperature, and need to be dissolved in advance when in use, and then the fatty alcohol-polyoxyethylene ether is added into a reaction system, so that the obtained finished product has general transparency. According to the invention, the fatty alcohol-polyoxyethylene ether AEO-9 which can be in a transparent liquid state at the temperature of more than 30 ℃ is preferably selected, so that the fatty alcohol-polyoxyethylene ether AEO-9 can be directly added into a reaction system without being dissolved in advance, and the method is simpler and more convenient, and the appearance transparency of the finished product is higher. The sodium fatty alcohol polyoxyethylene ether sulfate has excellent decontamination, permeation and wetting properties, and can achieve good cleaning power by being compounded with dodecyl benzene sulfonic acid ammonium salt, but the addition proportion of the sodium fatty alcohol polyoxyethylene ether sulfate needs to be controlled below 25 percent so as to avoid the influence of overhigh moisture content on the washing gel bead coated polyvinyl alcohol.

The triethanolamine and the dodecylbenzene sulfonic acid are subjected to neutralization reaction to generate dodecylbenzene sulfonic acid ammonium salt, and the method has the advantages of good emulsibility, wettability, dispersibility and detergency, biodegradability and environmental protection. The excessive triethanolamine and the N, N-dicarboxymethylalanine trisodium are compounded to serve as a chelating agent, so that metal ions in water are chelated, the hardness of the water is softened, and the adverse effect of the metal ions in the water on washing is eliminated. The N, N-dicarboxymethylalanine trisodium has better calcium and magnesium ion chelating ability than the traditional chelating agent (such as nitrilotriacetic acid, ethylenediamine tetraacetic acid and the like), and has high biodegradability and environmental protection. In addition, the N, N-dicarboxymethylalanine trisodium of the Acrossobel Dissolvine M-40 can effectively improve the detergency of the system.

The anti-redeposition agent is added into the formula, so that the action that the washed dirt is deposited on the fabric fiber again can be inhibited, and the fabric fiber still keeps the effect of brightness and cleanness after being washed for many times. The Unicap K25A styrene-acrylic acid hydrophobic modified copolymer has good fluidity, has outstanding compatibility in concentrated products, has synergistic effect with a surfactant, improves the cleaning effect, has excellent dirt dispersion force in the washing process, and inhibits the dirt from being redeposited on fabric fibers.

The detergency of the washing bead samples prepared in the first to third examples is measured, and the test result shows that the detergency of the washing bead samples with the concentration of 0.025 percent on carbon black, protein and sebum stains is greater than that of the standard washing liquid with the concentration of 0.2 percent, and the effect of 8 times of the detergency is achieved.
