Description

Technical Field

[0001] The invention relates to a washing and conditioning composition containing fresh aloe vera gel juice and a preparation method thereof. Background Art

[0002] In the current daily chemical industry, shampoo, shower gel, and other cleaning products, the primary foaming agent in the product formula is generally anionic surfactants. The most widely used anionic surfactants are sulfate anionic surfactants such as sodium lauryl sulfate, sodium laureth sulfate, ammonium lauryl sulfate, and ammonium laureth sulfate. These raw materials are mainly used as the main raw materials in the formulation of daily chemical cleaning products due to their strong foaming power, excellent detergency, easy thickening, and high cost performance. Because these sulfate anionic surfactant raw materials are viscous ointments at room temperature and solid at low temperatures in winter, their dispersion, dissolution, and defoaming are technical challenges during the production and processing of cleaning products. Dispersion often requires long periods of high-speed shearing. The large amount of foam generated by high-speed shearing requires long periods of high temperature to defoam. Otherwise, the excessive foam in the material will seriously affect the stability of the subsequent filling volume. The dispersion and defoaming processes are time-consuming and energy-consuming, significantly affecting product production efficiency and production costs. On the other hand, although sulfate anionic surfactants have good detergency, long-term contact can have a certain destructive effect on the skin and mucous membranes, causing skin inflammation and irritation. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a washing and conditioning composition containing fresh aloe vera gel juice and a preparation method thereof.

[0004] The technical problem to be solved by the present invention is achieved through the following technical solutions:

[0005] In a first aspect, a method for preparing a washing and conditioning composition containing fresh aloe vera gel juice comprises the following steps:

[0006] (1) Prepare the following materials in parts by weight: 60-80 parts of fresh aloe vera gel juice, 13-20 parts of sulfate anionic surfactant, 2-10 parts of amphoteric surfactant, 0-5 parts of softener, 1-2 parts of nonionic surfactant, 0.5-2 parts of pearlescent agent, 0.1-1.6 parts of cationic conditioner, 0.1-0.3 parts of stabilizer, 0.4-2 parts of thickener, 0.4-1 parts of preservative, and 0.3-1 parts of flavor;

[0007] (2) Mix the sulfate anionic surfactant and 50-70 parts of fresh aloe vera gel juice and homogenize for 10-20 minutes to completely disperse;

[0008] (3) A solid cationic conditioning agent is mixed with 4 to 6 parts of fresh aloe vera gel juice, heated and stirred to dissolve, and then added to the solution of step (2) and stirred evenly;

[0009] (4) Mix the stabilizer with 4 to 6 parts of fresh aloe vera gel juice, stir until completely dissolved, add it to the solution in step (3), and stir evenly;

[0010] (5) Stir and heat to 85°C and keep for 10 minutes for sterilization. There is no need to keep it at high temperature for defoaming, and cool it directly to below 50°C;

[0011] (6) Add the amphoteric surfactant, nonionic surfactant, liquid cationic conditioner, softener, pearlescent agent, preservative, flavor, and thickener to the cooled solution in sequence and stir to mix evenly;

[0012] Wherein, the viscosity of the aloe vera gel fresh juice is controlled at 200-300 mPa.s.

[0013] In the present invention, the homogenization speed in step (2) is controlled at 2000-3000 r / min.

[0014] In the present invention, the pH of the washing and conditioning composition containing fresh aloe vera gel juice prepared in step (6) is controlled at 5.5 to 6.0, and the viscosity is controlled at 5000 to 8000 mPa.s.

[0015] In the present invention, the average molecular weight of the aloe polysaccharide in the aloe gel juice is controlled to be 100-150 kDa.

[0016] In the present invention, no additional water is added during the preparation of the washing and conditioning composition containing fresh aloe vera gel juice.

[0017] The aloe vera gel juice is prepared by the following method: the washed organic aloe vera leaves are peeled and crushed and then transferred to a stabilization tank, the pH value is adjusted to 3.6-4.0 and 0.05% EDTA-2Na is added, and the stabilization treatment is carried out at a temperature of 80-85°C, and finally heat-treated, sterilized and cooled. Under aseptic conditions, the juice is separated to obtain aloe vera gel juice with a viscosity controlled at 200-300mPa.s and an average molecular weight of aloe polysaccharides controlled at 100-150kDa. In specific implementation, the aloe vera gel juice with suitable viscosity and molecular weight can be obtained by selecting organic aloe vera of different planting years and adjusting the stabilization treatment temperature and time, which will not be described in detail here.

[0018] In a second aspect, a washing and conditioning composition containing fresh aloe vera gel juice comprises the following raw materials in parts by weight: 60-80 parts of fresh aloe vera gel juice, 13-20 parts of sulfate anionic surfactant, 2-10 parts of amphoteric surfactant, 0-5 parts of softener, 1-2 parts of nonionic surfactant, 0.5-2 parts of pearlescent agent, 0.1-1.6 parts of cationic conditioner, 0.1-0.3 parts of stabilizer, 0.4-2 parts of thickener, 0.4-1 parts of preservative, and 0.3-1 parts of essence, wherein the viscosity of the fresh aloe vera gel juice is controlled at 200-300 MPa.s.

[0019] In the present invention, the sulfate anionic surfactant is at least one selected from sodium lauryl sulfate, sodium laureth sulfate, ammonium lauryl sulfate, and ammonium laureth sulfate.

[0020] In the present invention, the cationic conditioning agent is selected from at least one of polyquaternium-47, polyquaternium-10, guar hydroxypropyltrimonium chloride, polyquaternium-7, polyquaternium-22, and polyquaternium-39.

[0021] In the present invention, the stabilizer is selected from at least one of acrylic acid (esters) / C10-30 alkyl acrylate cross-polymer and acrylic acid (esters) copolymer.

[0022] In the present invention, the amphoteric surfactant is at least one selected from cocamidopropyl betaine, cocoyl hydroxysulfonyl betaine and cocamidopropyl hydroxysulfonyl betaine.

[0023] In the present invention, the nonionic surfactant is selected from at least one of cocamide methyl MEA, cocamide MEA, and cocamide DEA.

[0024] In the present invention, the softener is selected from at least one of dimethiconol, dimethicone and amodimethicone.

[0025] In the present invention, the pearlescent agent is selected from ethylene glycol distearate, and the thickener is selected from sodium chloride.

[0026] In the present invention, no additional water is added to the cleaning composition containing fresh aloe vera gel juice.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The preparation method of the washing and conditioning composition containing fresh aloe vera gel juice of the present invention uses specific fresh aloe vera gel juice instead of pure water as a medium, adds a sulfate anionic surfactant to the fresh aloe vera gel juice for homogeneous dispersion, and greatly accelerates the dispersion speed of the sulfate anionic surfactant in the fresh aloe vera gel juice due to the strong permeability of the bioactive water in the fresh aloe vera gel juice of a specific viscosity. At the same time, due to the specific viscosity of the fresh aloe vera gel juice, fewer bubbles are introduced during homogenization. After heating and stirring for sterilization, there is no need to maintain a high temperature for a long time for defoaming treatment, and the composition can directly proceed to the next process. This not only shortens the time required for dispersing the sulfate anionic surfactant, but also greatly improves production efficiency and reduces energy consumption by eliminating the need for defoaming waiting.

[0029] Using fresh aloe vera gel juice and controlling the appropriate amount of addition can build a protective barrier for the skin surface, protect the skin and mucous membranes from the influence of surfactants to the greatest extent, and reduce the risk of skin irritation.

[0152] This comparative example uses the formula of Example 2, but replaces the aloe vera gel juice with 50% purified water + 50% aloe vera gel juice, i.e., 32.3 parts purified water + 32.3 parts aloe vera gel juice to form a mixed medium. The aloe vera polysaccharide in the aloe vera gel juice has an average molecular weight of 138 kDa and a viscosity of 248 mPa.s. The preparation method of the washing and conditioning composition comprises the following steps:

[0153] (1) Prepare the materials according to the weight of the above raw materials;

[0154] (2) Mix the sulfate anionic surfactant and 54.6 parts of the mixed medium, start homogenization, control the homogenization speed at 2800 r / min, and keep it for 35 minutes until it is completely dispersed and there is a lot of foam in the material;

[0155] (3) A solid cationic conditioning agent (guar gum hydroxypropyltrimonium chloride) is mixed with 4 parts of the mixed medium, heated and stirred to dissolve, and then added to the solution of step (2) and stirred evenly;

[0156] (4) Mix the stabilizer with 6 parts of the mixed medium, stir until completely dissolved, add it to the solution in step (3), and stir evenly;

[0157] (5) Stir and heat to 85℃ for sterilization, and keep it for 10 minutes. Because there is a lot of foam in the material, keep it above 80℃ and let it stand for 3 hours to eliminate the foam to the ideal state, and then cool it to below 50℃;

[0158] (6) Add an amphoteric surfactant, a nonionic surfactant, a liquid cationic conditioner, a softener, a pearlescent agent, a preservative, a fragrance, and a thickener to the solution of step (5) in sequence, and stir and mix evenly to obtain a cleaning composition with a pH of 5.82 and a viscosity of 5128 mPa.s.

[0159] The cleaning compositions prepared in Example 1 to Comparative Example 6 were subjected to an acute skin irritation test. The test results are shown in Table 1.
