Description

Technical Field

[0001] This invention relates to the field of daily chemical products technology, and in particular to a mite-removing cleaning agent composition, its preparation method, and its application. Background Technology

[0002] Dust mites are a common allergen in daily life. They thrive in indoor environments with a temperature of around 30°C and a relative humidity of 60-80%, and can multiply rapidly in mattresses, blankets, sweaters, and other fabrics. Dust mite excrement, shells, and carcasses can clog pores or trigger allergic reactions, leading to a range of allergic diseases. The mechanisms of action of mite-removing cleaners are mainly divided into two categories: washing and killing. Washing removes attached mites by cleaning the surface, but their activity may remain, allowing them to continue to reproduce and metabolize. Killing, on the other hand, inactivates the mites, preventing them from reproducing and excreting. Consumers generally prefer mite-removing cleaners with killing properties because they more thoroughly eliminate the potential allergen. At the same time, there is an increasing market demand for green and gentle ingredients, with expectations that products effectively kill mites while being non-toxic and non-irritating to users.

[0003] Currently, many mite-removal products claim to use natural extracts, but the proportion of ingredients in natural extracts may vary between different batches, and their mite-removal effect is often unstable and poor. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a mite-removing cleaning composition that has a stable and efficient mite-removing effect.

[0005] First aspect: A mite-removing cleaning agent composition comprising the following components: Alkyl alcohol polyoxyethylene ether carboxylates and alkyl imidazoline phosphates; The alkyl alcohol polyoxyethylene ether carboxylate has the following general chemical formula:

[0006] Wherein, the R1 group contains 6 to 22 carbon atoms; n represents the degree of polymerization, which is 2 to 30; X + The equilibrium ions of carboxylate salts include at least one of hydrogen ions, lithium ions, sodium ions, potassium ions, ammonium ions, and magnesium ions. The alkyl imidazoline phosphate salt has the following general chemical formula:

[0007] The R2 group contains 6 to 22 carbon atoms; the R3 group is a hydrogen group, a methyl group, or an ethyl group.

[0008] This invention creatively combines alkyl alcohol polyoxyethylene ether carboxylate salt and alkyl imidazoline phosphate salt to form a weak electrolyte complex. Because the ionic groups in both surfactant molecules are relatively small (the former is a weak anion and the latter a weak cation), they complex through the carboxylate anion and the imidazoline cation, forming a complex with a weaker overall charge and enhanced hydrophobicity, without forming a precipitate that is poorly soluble in water. The composition is predominantly hydrophobic and electrically neutral, with a small ionic proportion, exhibiting overall weakly charged macromolecules, thus possessing mild and non-irritating properties.

[0009] The mechanism of action of this composition in killing mites is as follows: alkyl imidazoline phosphate salts have a structure similar to the phospholipids in the mite epidermis, thus exhibiting high adsorption capacity on the mite epidermis; in addition, by compounding alkyl alcohol polyoxyethylene ether carboxylate surfactants with alkyl imidazoline phosphate salt surfactants, the adsorption of alkyl imidazoline phosphate salt surfactants on the mite epidermis can be synergistically enhanced. When the adsorption reaches a certain level, the hydrophobic chains of the surfactant molecules align outwards, making the mite epidermis hydrophobic, thereby blocking its absorption of moisture from the air, interfering with its normal respiratory metabolism, and ultimately achieving the effect of killing mites.

[0010] R1 and R2 groups are molecular chain segments with 6 to 22 carbon atoms. On the one hand, the raw materials are simple and readily available, and on the other hand, they take into account the special properties of hydrophilicity and hydrophobicity required by surfactant molecules. If the number of carbon atoms is too small, the hydrophobic chain is too short and the molecule is too hydrophilic; if the number of carbon atoms is too large, the hydrophobic chain is too long and the molecule is too hydrophobic. An imbalance of hydrophilicity and hydrophobicity will cause the molecule to lose its surfactant function.

[0011] Within a certain range, the higher the degree of polymerization of alkyl alcohol polyoxyethylene ether carboxylate, the better the hydrophilicity. At the same time, the hydrophilic-hydrophobic balance of surfactant molecules is taken into account. If the polymerization is too high, the molecular hydrophilicity is too strong, resulting in poor surface activity of the molecules, which may prevent them from forming an effective composition with imidazoline phosphate salt.

[0012] As a preferred embodiment, the R1 group is an alkyl, alkenyl, or an aromatic group containing a benzene ring; the R2 group is an alkyl, alkenyl, or an aromatic group containing a benzene ring.

[0013] As a preferred embodiment, the molar ratio of the alkyl alcohol polyoxyethylene ether carboxylate to the alkyl imidazoline phosphate is 1:9 to 9:1. If the content of the alkyl alcohol polyoxyethylene ether carboxylate is too low, it will not be able to assist the adhesion of the alkyl imidazoline phosphate; if the content of the alkyl imidazoline phosphate is too low, the mite-killing ability will be too weak.

[0014] As a preferred embodiment, the system further includes a first solvent, wherein the first solvent is water.

[0015] As a preferred embodiment, the total mass of the alkyl alcohol polyoxyethylene ether carboxylate and the alkyl imidazoline phosphate salt accounts for 0.1% to 30% of the mass of the composition. If the content is too low, it will not be effective in eliminating mites; if the content is too high, it will be difficult to dissolve.

[0016] As a preferred embodiment, the composition further includes a gain-enhancing agent, wherein the gain-enhancing agent accounts for 0-5% of the total mass of the composition; the gain-enhancing agent includes at least one of surfactants, rheology modifiers, pH adjusters, chelating agents, detergent polymers, anti-dye transfer agents, enzyme preparations, enzyme stabilizers, fluorescent whitening agents, bleaching agents, bleaching catalysts, polymer dispersants, bactericides, bacteriostatic agents, acaricides, defoamers, antifoaming agents, preservatives, opacifiers, pigments, fragrances, fragrance microcapsules, structured suspending agents, water-soluble additives, and solubilizers.

[0017] As a preferred embodiment, the composition further includes a second solvent, which constitutes 0-20% of the total mass of the composition. The second solvent is an organic solvent, including at least one selected from ethanol, ethylene glycol, 1,2-propanediol, 1,3-propanediol, glycerol, dipropylene glycol, and isopropanol. The second solvent is used to assist in the dissolution of alkyl alcohol polyoxyethylene ether carboxylates, alkyl imidazoline phosphates, and additives.

[0018] As a preferred embodiment, the fragrance comprises at least one of benzyl salicylate, citral, isobutyl valerate, and vanillin.

[0019] The second aspect: A method for preparing a mite-repellent cleaning composition as described in the first aspect comprises the following steps: Mix 80% of the total mass of water with the alkyl alcohol polyoxyethylene ether carboxylate. After the alkyl alcohol polyoxyethylene ether carboxylate is completely dissolved, add the alkyl imidazoline phosphate salt. After the alkyl imidazoline phosphate salt is completely dissolved, add the remaining 20% ​​of the total mass of water and stir until homogeneous to obtain the mite-removing cleaning agent composition.

[0020] Third aspect: The application of a mite-removing cleaning composition as described in the first aspect is applicable to mite-removing infusions, mite-removing sprays, fabric detergents, fabric softeners, carpet cleaners, floor cleaners, antistatic care agents, facial cleansers, shower gels, shampoos, foot baths, hand soaps, facial lotions, body lotions, hand creams, face towels, cleaning wipes, air fresheners, deodorizers, and antiperspirants.

The petri dish and mounting plate were placed together in a covered container lined with sponges, and an appropriate amount of saturated saline solution was added (the water level just submerged the sponges). 200 test mites were placed in the center of each petri dish, and 0.05g of mite feed was added to the center of the petri dish after 30 minutes. The container was placed in a constant temperature and humidity incubator at a temperature of (25±2)℃ and a humidity of (70±5)%.

[0064] As can be seen from the above embodiments, when alkyl alcohol polyoxyethylene ether carboxylate and alkyl imidazoline phosphate are combined in the mite-removing cleaner, the mite removal rate reaches 100%. However, when alkyl alcohol polyoxyethylene ether carboxylate is added alone, the mite removal rate is lower because alkyl alcohol polyoxyethylene ether carboxylate itself does not have a significant killing effect on mites. Adding alkyl imidazoline phosphate alone has a certain mite-removing effect, but it is still somewhat different from the mite-removing effect of the combined product.

[0065] The above embodiments are merely illustrative of several implementations of the present invention, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the invention patent. For those skilled in the art, various modifications and improvements can be made without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
