Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of daily chemical washing products, in particular to a soap composition containing microcapsule perfume and a production method thereof. BACKGROUND

[0002] Soap is the oldest washing product used by human beings, and has a history of thousands of years. As a traditional washing product, soap has the advantages of natural raw material, good safety performance, excellent biodegradability, mild performance, strong decontamination, easy rinsing, and no pollution to the environment, and has become an indispensable washing product in consumers' daily life. The fatty acid salt derived from natural oil is the main raw material of soap, and some oil odor is difficult to completely remove in the saponification reaction or oil hydrolysis, fatty acid neutralization process, so soap will have some oil-specific odor. At the same time, with the passage of time, the unsaturated carbon chain fatty acid in the soap may undergo oxidation reaction to produce rancid odor. The fabric washed with soap often has soap base odor or weak fragrance, and the change of modern lifestyle makes more and more people like to leave a fragrance on their clothes. The addition of perfume can effectively solve the problem of clothes leaving a fragrance, but the traditional perfume is easy to volatilize, and the storage and packaging characteristics of soap further increase the possibility of volatilization, which is not effectively utilized. Moreover, most of the ordinary liquid perfume is washed away during the washing and rinsing process, and there is basically no fragrance after the clothes are dried, and the odor of soap base is easily reflected on the clothes.

[0003] The application of microcapsule perfume in daily washing products is mainly in washing powder and washing liquid products, which has been successfully applied. The application of microcapsule in liquid detergent or powder detergent has been disclosed in the prior art, but the application in soap products is still a technical blank. The difficulty of applying microcapsule perfume in soap is that microcapsule perfume is difficult to stably exist in the traditional formula of soap, and the production process of soap needs grinding and extrusion. If the microcapsule perfume is directly added to the soap combination formula, it is easy to be damaged and crushed, so that the essential oil in the microcapsule perfume is released, which is basically the same as the traditional liquid perfume added, and the effect of long-lasting fragrance of microcapsule perfume cannot be achieved. SUMMARY

[0004] The technical problem to be solved by the present application is that the microcapsule perfume is difficult to stably exist in the formula of soap products, and the microcapsule shell is easily damaged by the production process of soap, so the application is limited. Therefore, one object of the present application is to provide a soap composition containing microcapsule perfume and a production method thereof, which can realize the stable existence of microcapsule perfume in soap and excellent long-lasting fragrance effect after washing.

[0005] In order to solve the above problems, the present application proposes the following technical scheme:

[0010] Further, the soft water aid includes any one or a mixture of two or more of 4A zeolite, sodium carbonate, diethylene triamine penta(methylene phosphonic acid), ethylene diamine tetra(methylene phosphonic acid), hexamethylene diamine tetra(methylene phosphonic acid), hydroxyethylidene diphosphonic acid, ethylene diamine tetraacetic acid, diethylene triamine pentaacetic acid, ethylene diamine disuccinic acid, ethylene diamine diacid, 2-hydroxypropylenediamine disuccinic acid, or any salt thereof.

[0011] Further, the microcapsule perfume is composed of core perfume and shell coating layer. The shell coating layer can be composed of one layer, two layers or more than two layers.

[0012] Further, the shell coating layer is made of one, two or more than two of urea-formaldehyde resin, methylated melamine-formaldehyde resin, aldehyde and thiourea, N-alkyl urea, guanidine, acetyl guanidine, benzoguanamine, 2,4-diamino-6-nonyl-1,3,5-triazine, cyanamide, dicyandiamide, aryl sulfonamide, alkyl sulfonamide, gelatin, starch, carboxymethyl cellulose, wax, vinyl pyrrolidone, gum arabic, polyurea, polyurethane, amine, glutaraldehyde, isocyanate, epoxide or silicate coupling agent, polyacrylic acid, pullulan, or a reaction product thereof.

[0013] Further, the stabilizer is a mixture of glycerin, starch, dimethicone and magnesium lithium silicate.

[0014] Further, the other auxiliary agent includes a coloring agent, glycerin, propylene glycol, sorbitol, sucrose, an inorganic additive and a functional additive.

[0015] The inorganic additive is selected from any one or a mixture of two or more than two of kaolin, barium sulfate, calcium carbonate, talc, silica and bentonite.

[0016] The functional additive includes any one or a mixture of two or more than two of an enzyme preparation, a bactericide, an anti-redeposition agent, a whitening agent, a softening agent and an antioxidant.

[0017] The application also provides a production method of the soap composition containing the microcapsule fragrance as described above, which comprises the following steps:

[0018] 1) adding weighed soap particles into a stirring pot and stirring and crushing them uniformly; the soap particles are a mixture of sodium fatty acid and water in a certain proportion prepared by saponification reaction or hydrolysis and neutralization reaction of natural oil;

[0019] 2) adding a surfactant and stirring uniformly;

[0020] 3) adding other auxiliary agents, water softening agents and the rest of water and stirring uniformly;

[0021] 4) adding traditional fragrance or microcapsule fragrance and a stabilizer mixture, stirring uniformly, and sequentially passing the uniform material through a refiner, a three-roll grinding machine, a vacuum bar extruder, a rolling (or printing) former, a cutting machine and a packaging machine to obtain the soap composition containing the microcapsule fragrance.

[0022] Preferably, the refining mesh size of the refiner and the vacuum bar extruder is in the range of 0.5 mm-5 mm.

[0023] Preferably, the refining mesh size of the refiner and the vacuum bar extruder is in the range of 1.0 mm-4.5 mm.

[0024] Preferably, the refining machine and the refining screen installed in the vacuum bar extruder have a mesh size in the range of 1.5mm-4mm.

[0025] More preferably, the refining machine and the refining screen installed in the vacuum bar extruder have a mesh size in the range of 2mm-4mm.

[0026] Preferably, the three-roll mill has a roll gap of 0.1-2.5mm.

[0028] More preferably, the three-roll mill has a roll gap of 0.3-1mm.

[0029] It should be noted that too small mesh size of the refining screen installed in the refining machine and the vacuum bar extruder and too small roll gap of the three-roll mill can easily cause the microcapsule fragrance to be squeezed, broken and volatile, affecting the fragrance retention time. Too large mesh size of the refining screen installed in the refining machine and the vacuum bar extruder and too large roll gap of the three-roll mill can cause uneven formula material and poor soap body forming and cracking.

[0030] Compared with the existing ordinary soap, the advantages of the present application are:

[0031] 1. The soap composition containing microcapsule fragrance provided by the present application is an effective combination of soap and microcapsule fragrance. After process production and stability test verification, the microcapsule fragrance can effectively coexist with the liquid fragrance and other ingredients in the soap composition, play its respective functions and have a synergistic effect.

[0032] 2. The microcapsule fragrance in the soap composition containing microcapsule fragrance provided by the present application can effectively bind with fabric fibers and is not easily washed away by water during the rinsing process, and is still retained between the fibers of the clothes until the clothes are dried. The liquid fragrance added in the ordinary soap is easily volatile and lost during storage, and is almost washed away during rinsing. The fabric has no obvious fragrance or even no fragrance after washing. The addition of microcapsule fragrance in the soap can deposit the microcapsule fragrance on the fabric fibers during washing. The fabric continuously produces physical friction during washing, rinsing, drying, folding and wearing, the wrapping layer of the microcapsule fragrance is broken, and the fragrance is gradually released, which not only masks the odor of the soap base, but also realizes long-lasting fragrance retention, making people feel happy.
