Description
Technical Field
The invention relates to the field of washing products, in particular to a sulfur laundry detergent and a preparation method thereof.
Background
With the improvement of living standard, people pursue clean, healthy and fashionable life, thereby promoting the development and upgrading of washing articles. The washing products are continuously optimized in product structure, the variety is increasingly increased, the development is towards the directions of functionalization, specialization, subdivision and environmental protection, the washing products with the concepts of enzyme addition, bacteriostasis, mite removal, washing and protection, such as 'aerobic washing', are continuously emerging, and functional products such as clothes pre-washing agent, clothes softener, clothes fragrance retention agent, clothes disinfectant, clothes bleaching agent, and the like are continuously layered, and the novel product forms such as clothes condensation beads, clothes fragrance retention beads, clothes soaps, clothes effervescent tablets, clothes mousse, and the like are also presented, so that the washing products are popular for young families.
The laundry products currently in common use are mainly the following:
(1) The traditional washing product is mainly washing powder and is characterized by low cost and strong cleaning power, but alkaline clothes washing has stimulation to skin, has single washing function, large dosage and difficult rinsing, and is easy to cause the problems of clothes damage, color shifting and the like;
(2) The laundry detergent improves the problem of strong alkalinity of the laundry powder to a certain extent, has mild performance, can reduce the damage to clothes, but causes the problems of weak cleaning power and large consumption, and the laundry detergent products on the market are more chaotic, the counterfeit products are layered endlessly, the formula is unstable, and the corresponding washing effect can not be realized;
(3) The emerging forms of laundry products are focused on the novelty of the forms, and the actual use effect is not ideal and the use mode is single. For example, the laundry soap is water-containing laundry powder in practice, and is made into soap blocks, so that the laundry soap is convenient for people to wash by hands and locally wash clothes, and has the defect of being incapable of being washed by a machine; the laundry products such as laundry gel beads, effervescent tablets, laundry mousse and the like are manufactured into sheets or particles, the use amount is more accurate, the laundry products can be added according to the laundry requirement, and relatively more water is saved, but the laundry products are not suitable for hand washing and are not suitable for local treatment of clothes, waste is easily caused when 1 and 2 clothes are washed, the production cost and the product price are high, and the life cycle of the product is short.
In addition, the commercial laundry products rarely achieve true "all-in-one" because laundry relies on high detergency, while the laundry relies on softeners, bleach whitening ingredients, which are actually contradictory in the formulation system. In addition, the antibacterial, mite-removing, disinfecting and sterilizing laundry products have the same formulation difficulties, because most bactericides are cationic components, are not compatible with anions in the formulation of the laundry liquid, and the surface activity of the anions is an indispensable key core component in the laundry liquid. Therefore, the washing product which has a wide application mode, can realize effective washing and caring, and has the functions of bacteriostasis and mite removal is provided, and becomes an important research direction in the field.
The problems of coexistence of the traditional bactericide and anions are solved by researching to use PCMX, TCS, TCC, HP and other chlorine-containing disinfectants in detergents for sterilization, but the problems of use safety, biodegradability and drug resistance are argued by public opinion and are not applicable to laundry products.
In addition, there are studies on the effect of inhibiting bacteria and removing mites by adding sulfur into a laundry detergent, but the sulfur is pale yellow brittle crystals or powder with a relative density (water=1) of 2.0 and is almost insoluble in water, and the sedimentation rate in an aqueous solution system is very fast, so that the suspension stability of the laundry detergent product is poor and the fluidity is poor, thereby affecting the quality and the use effect of the laundry detergent and being difficult to meet the actual application demands. In addition, some laundry detergent products have a large foaming amount, and have the problems of difficult rinsing and water and time consumption.

The invention provides a sulfur laundry detergent, which comprises the following raw material components in percentage by mass:
the thickener is one or more selected from acrylic copolymer, xanthan gum and polyethylene glycol distearate.
The usual way to suspend particles or solids in a solution is to increase the viscosity of the solution system. Inorganic thickening agents are flocculent substances formed by water absorption expansion of inorganic salts and are combined with water to form charged colloid, so that thickening is realized, but common inorganic thickening agents are not suitable for thickening a liquid laundry detergent system containing sulfur, and because the water-solubility speed is not fast enough after thickening, the suspension property is poor and the fluidity is poor; the cellulose thickener is characterized in that the hydrophobic main chain and surrounding water molecules are associated by hydrogen bonds, so that the flowing volume of the polymer is increased, the free movement space of particles is reduced, and the viscosity of a system is increased; the thickening of polyacrylic acid high molecular polymer is that carboxylic acid radical ions generate like static repulsive force through dissolving in water, molecular chains are extended into a rod shape from a spiral shape, thus the viscosity of water phase is improved, and the thickening agent greatly improves the viscosity in a system, but the formed thickening structure still cannot bear the gravity sedimentation of sulfur particles, is easily interfered by ions, and can dilute the system again, or the suspension can be destroyed if slight condition change exists, so that only short-time suspension can be realized.
In the invention, the viscosity of the system can be effectively increased by adopting specific types of thickening agents to be compatible with anionic surfactant, nonionic surfactant, sulfur and the rest of components and reasonably adjusting the proportion of each raw material component.
In one example, the thickener is one or more of xanthan gum and polyethylene glycol distearate and acrylic ester copolymer. Further, the acrylic copolymer is a lightly crosslinked acrylic copolymer.
In the invention, carboxyl in hydrophilic monomer of acrylic copolymer is neutralized into salt in sulfur laundry detergent system, electrostatic repulsion is generated in molecules, macromolecular chains are gradually stretched, a large number of surrounding water molecules are adsorbed, thus restricting free movement of water molecules, the viscosity of the system is increased apparently, meanwhile, main chains on the hydrophilic monomer are associated with latex particles in the system, forming a large three-dimensional network structure, restricting free movement of emulsion particles, further increasing the viscosity of the system, further reasonably matching with other components in the sulfur laundry detergent, enabling the three-dimensional network structure to wrap sulfur particles uniformly dispersed in the system, overcoming gravity sedimentation of sulfur, forming stable product state, and the prepared sulfur laundry detergent has good stability and fluidity, and because the consistency of the system is obviously increased, foam formation is inhibited, the production condition is more convenient and faster without adopting a vacuumizing defoaming process, the prepared sulfur laundry detergent is easier to rinse clean in actual use, the greasy feeling of residual foam is avoided, and the problems of difficult rinsing and water consumption of the laundry detergent are avoided.
In one example, the thickener is selected from one or more of liquid carbomers, xanthan gum, and polyethylene glycol distearate. Further, the thickener is one or more of xanthan gum and polyethylene glycol distearate and is compounded with liquid carbopol. The invention is not limited to the type of liquid card wave, including but not limited to liquid card wave SF-1.
In one example, the anionic surfactant is selected from one or more of sodium fatty alcohol polyoxyethylene ether sulfate, sodium fatty acid methyl ester sulfonate, fatty acid potassium soap, potassium myristate soap, and potassium laurate soap. Further, the anionic surfactant is selected from one of sodium fatty alcohol polyoxyethylene ether sulfate, sodium fatty acid methyl ester sulfonate, fatty acid potassium soap, potassium myristate soap and potassium laurate soap.
In the invention, the specific type of anionic surfactant has high detergency to protein dirt and good compounding effect with nonionic surfactant.
In one example, the nonionic surfactant is selected from one or more of fatty alcohol polyoxyethylene ether, alkyl glycoside, isomeric tridecyl alcohol polyoxyethylene ether, and coconut fatty acid diethanolamide.
In the invention, the nonionic surfactant of a specific type has better emulsifying capability and good compatibility, and can play better synergistic action by being compounded and cooperated with the anionic surfactant, and the nonionic surfactant has high detergency to grease and solid particle dirt, is easy to rinse, and can cooperate with a low-foam thickening system to promote the easy rinsing effect of the sulfur laundry detergent.
In one example, the stabilizer is selected from one or more of disodium ethylenediamine tetraacetate (EDTA-2 Na), sodium citrate, and sodium silicate.
In the invention, the reasonable addition of the stabilizer can prevent the washing effect from being reduced when hard water is used for washing, and can improve the stability of the system by cooperating with the thickener.
In one example, the sulfur is selected from one or more of 200-400 mesh sulfur powder and sulfur powder with particle size less than 50 nm.
It can be understood that sulfur has various effects, especially has special effects on mites, can effectively kill mites, inhibit bacteria and kill insects, is harmless to people and animals, and in addition, the addition of sulfur in the laundry detergent has the effects of bleaching and brightening. The sulfur is insoluble in water, and the sedimentation speed in an aqueous solution system is very high, so that the suspension stability of the laundry detergent product is poor, the fluidity is poor, and the quality and the use effect of the laundry detergent are affected. According to the invention, sulfur, a specific type of thickener, a surfactant and the rest of components are reasonably matched, so that the sulfur can be well dispersed and stably suspended in a laundry detergent system, and the technical problem that antibacterial laundry detergent or bactericide is difficult to compound is solved. Furthermore, the sulfur powder with specific particle size is adopted to be compatible with the rest raw material components in the invention, which is beneficial to improving the dispersion and suspension effect of sulfur solid particles in the system.
In one example, the sulfur laundry detergent comprises the following raw materials in percentage by mass:
it can be understood that essence can be added into the sulfur laundry detergent in proper amount, so that the cleaned clothes are endowed with fresh and elegant fragrance, and the use feeling of the product is improved. In the present invention, the kind of the essence is not particularly limited, and may be selected from the kinds of essences conventional in the art. Further, the essence is extracted from natural plants.
The invention also provides a preparation method of the sulfur cleaning agent, which comprises the following steps:
mixing the raw material components to prepare the sulfur laundry detergent.
In one example, the method for preparing the sulfur laundry detergent comprises the following steps:
mixing deionized water, an anionic surfactant, a nonionic surfactant and a stabilizer, and stirring for the first time to prepare a mixed solution A;
adding a thickening agent into the mixed solution A, and stirring for the second time to prepare a mixed solution B;
and adding sulfur into the mixed solution B, and stirring for the third time to prepare the sulfur laundry detergent.
It can be appreciated that essence can be added in proper steps when preparing the sulfur laundry detergent, so that the use feeling of the product can be improved. Further, the preparation method of the sulfur laundry detergent comprises the following steps:
deionized water, anionic surfactant, nonionic surfactant, stabilizer and essence are mixed and stirred for the first time to prepare a mixed solution A.
In one example, in the second stirring step, the pH is adjusted to 6.5 to 7.5. It is understood that adjusting the pH may employ pH adjusters conventional in the art, including but not limited to: triethanolamine, and citric acid.
In one example, the method for preparing the sulfur laundry detergent further comprises the following steps:
sieving sulfur with 18-50 mesh sieve, adding into the mixed solution B, and stirring for the third time.
In one example, the rotational speed of the first stirring is 500r/min to 800r/min. The stirring time is not limited until the components are dissolved.
In one example, the conditions of the second agitation include: the rotating speed is 1000 r/min-1500 r/min, and the time is 10 min-20 min.
In one example, the conditions for the third agitation include: the rotating speed is 1000 r/min-1500 r/min, and the time is 25 min-35 min.
In the invention, the speed of the third stirring is not too high and the time is not too long, so that the shearing can be prevented from damaging the three-dimensional network structure in the system.
The present invention will be described in further detail with reference to specific examples. The raw materials, reagents and the like used in the following examples were obtained from commercial products unless otherwise specified.

According to the results, the sulfur liquid laundry detergent prepared in the embodiments 1 to 3 of the invention has high suspension stability, better fluidity, obvious low-foam effect in washing, easy rinsing, strong detergency, high mite washing and removing rate and high sterilizing rate.
The sulfur laundry detergent prepared in comparative example 1 has poor suspension stability, particles are precipitated at the bottom, layering and serious color change occur, the formula is unstable, and the mite removal effect is obviously reduced. The sulfur laundry detergent prepared in comparative example 2 has the advantages of turbid appearance, difficult dispersion and poor suspension effect, also overcomes the gravity sedimentation of heavy-density sulfur particles, and obviously reduces the mite removal effect due to the precipitation of the particles at the bottom. In addition, comparative examples 1 and 2 had problems of large foam and difficulty in rinsing during the cleaning process.
In comparative example 3, excessive thickener is adopted, the proportion of each component is different from that of the invention, the prepared sulfur laundry detergent is in a pasty state, the sulfur laundry detergent is in a pasty state when being prepared, and the sulfur laundry detergent is difficult to dissolve, free of fluidity and difficult to rinse in the cleaning process after being cooled.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
