Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of natural fine chemical preparation, in particular to an antistatic composition containing natural jojoba oil and sweet almond oil and application thereof. BACKGROUND

[0002] With the increasing demand for functionalization of textiles, antistatic treatment technology has become an important research direction in the textile industry. Traditional antistatic agents mostly use synthetic silicone oil, polyether compounds or ionic surfactants, which can improve the problem of static accumulation of fabrics in the short term, but have environmental and health risks: synthetic silicone oil is difficult to degrade and easy to accumulate in the body, and long-term use of ionic surfactants can cause fabric yellowing or fiber damage. In addition, antistatic agents based on petroleum derivatives are prone to release volatile organic compounds during processing, which does not meet the trend of green manufacturing.

[0003] The existing natural antistatic composition lacks effective regulation of the microstructure, and cannot balance the viscosity, surface tension and stability of active ingredients. Most formulations only simply compound oil and essential oil without considering the influence of volatile rate gradient on functional durability, and high volatile essential oil is easy to lose during processing or storage; the traditional emulsification process is difficult to control the particle size of the dispersed phase, resulting in easy separation of the emulsion and affecting the uniformity of fabric treatment. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides an antistatic composition containing natural jojoba oil and sweet almond oil and application thereof, which solves the ecological toxicity problem caused by the dependence of traditional antistatic agents on synthetic chemicals, the performance decay problem caused by the poor stability of multi-component natural essential oil system, and the problem of damage to heat-sensitive active ingredients in high-temperature processing.

[0005] To achieve the above purpose, the present application is realized by the following technical scheme:

[0006] An antistatic composition containing natural jojoba oil and sweet almond oil, comprising, by weight percentage: 38-48% jojoba oil, 22-32% sweet almond oil, and the weight ratio of jojoba oil to sweet almond oil is 1.2:1-1.8:1; 5-12% grape seed oil; wherein the total content of jojoba oil, sweet almond oil and grape seed oil is 70-85%; 3-8% beeswax with a melting point of 62-67℃; 0.2-0.8% lemon essential oil; 0.8-3.0% rosemary essential oil; 0.5-1.5% thyme essential oil; 1.5-4.0% cedar essential oil; 2.5-4.5% tea tree essential oil; 0.8-3.0% eucalyptus essential oil; 0.8-2.5% lavender essential oil; 0.8-2.0% mint essential oil; and the composition does not contain synthetic silicone oil and ionic surfactant; the composition further comprises a balance of deionized water, so that the sum of the weight percentages of the components is 100%.

[0007] By adopting the technical scheme, the ternary compound oil phase system is constructed by using natural jojoba oil, sweet almond oil and grape seed oil. The jojoba oil has a similar wax ester structure to human sebum, and can give the composition excellent permeability and skin affinity. The sweet almond oil can improve the emulsion stability of the system by a high proportion of unsaturated fatty acids. The polyphenol substances contained in the grape seed oil and the trace amount of tocopherol can synergistically play an antioxidant protection role. The system completely abandons the traditional synthetic silicone oil and quaternary ammonium salt type surfactant, and avoids the introduction of environmental hormones such as alkylphenol polyoxyethylene ether from the source. At the same time, by establishing a layered and slow-release mechanism of low-volatility cedarwood oil, medium-volatility tea tree oil and high-volatility peppermint oil, the time sequence coverage of the static electricity neutralization function is realized. The long-acting adsorption of the cedarwood oil can reduce the surface resistivity, the antibacterial activity of the tea tree oil can reduce the charge accumulation, and the instantaneous volatilization of the peppermint oil can quickly neutralize the friction charge.

[0030] From 35°C to 25°C: cooling rate 0.5-0.7°C / min;

[0031] 25℃ constant temperature aging stage: humidity is controlled at 30-50% RH.

[0032] Preferably, the addition interval of each essential oil component in S3 is 2-5 minutes, and after each addition of a component, stirring is carried out at a low speed of 100-200 rpm for 3 minutes.

[0050] Please refer to the attached Figure 1 A method for preparing the antistatic composition containing natural jojoba oil and sweet almond oil, for the antistatic composition containing natural jojoba oil and sweet almond oil described above, the method comprising the following steps:

[0051] S1, melting treatment: melt the beeswax at 65-75°C and keep it for 10-20 minutes;

[0052] S2, oil phase construction: preheat the jojoba oil, sweet almond oil and grape seed oil to 55-60°C, and add them to the melted beeswax in S1, stirring at 300-500 rpm for 20-40 minutes;

[0053] S3, gradient addition of essential oils: cool to 40-45°C, and add the complex essential oil components in order of increasing volatility, including:

[0054] Low-volatility group: cedarwood essential oil and eucalyptus essential oil,

[0055] Medium volatile group: tea tree essential oil and rosemary essential oil,

[0056] High volatile group: lavender essential oil, thyme essential oil, mint essential oil and lemon essential oil;

[0057] S4, homogenization treatment: high pressure homogenization at 50-80 MPa, 40-45℃ for 3-5 times, controlling the dispersed particle size of essential oil to be 50-200nm;

[0058] S5, solidification forming: programmed temperature reduction to 25℃ at a rate of 0.5-1℃ / min, standing and aging for 24-48 hours.

[0059] Specifically, by melting the beeswax at 65-75℃ and keeping it for 10-20 minutes, the beeswax is completely melted and the impurities are reduced, thereby ensuring the uniformity of the subsequent mixing and improving the stability of the product; by preheating the jojoba oil, sweet almond oil and grape seed oil to 55-60℃ and mixing them with the melted beeswax, and stirring at 300-500rpm for 20-40 minutes, a uniform oil phase is formed and the fusion of each oil component is promoted, thereby improving the uniformity of the product and improving the smearing property; by adding the essential oils of different components at 40-45℃ in order of decreasing volatility, the order of essential oil addition is controlled and the loss of volatile is reduced, thereby maintaining the active ingredients of essential oil and optimizing the release of aroma; by high pressure homogenization at 50-80 MPa, 40-45℃ for 3-5 times, the dispersed particle size of essential oil is refined and the uniform distribution is improved, thereby enhancing the stability of the product and improving the use effect; by programmed temperature reduction to 25℃ at a rate of 0.5-1℃ / min, and standing and aging for 24-48 hours, the product is gradually solidified and a uniform structure is formed, thereby improving the stability of the product and prolonging the shelf life.

[0060] Please refer to the attached Figure 1 The temperature gradient of each component in S3 is controlled as follows:

[0061] Low volatile group addition temperature 45±2℃;

[0062] Medium volatile group addition temperature 43±2℃;

[0063] High volatile group addition temperature 40±1℃;

[0064] Temperature fluctuation throughout the process ≤±0.5℃.

[0065] Specifically, by controlling the addition temperature of cedarwood oil and low-volatility group essential oil of eucalyptus oil at 45±2℃, the loss of active ingredients of essential oil caused by excessively high temperature is avoided, and the effects of maintaining the efficacy and stability of essential oil are achieved; by controlling the addition temperature of tea tree oil and volatile group essential oil of rosemary oil at 43±2℃, the effects of reducing the volatility of essential oil and optimizing the uniformity of mixing are achieved, and the effects of improving the dispersibility of essential oil and improving the uniformity of the product are achieved; by strictly controlling the addition temperature of lavender oil, thyme oil, peppermint oil and lemon oil in the high-volatility group essential oil at 40±1℃, the effects of reducing the volatility of essential oil to the greatest extent and maintaining the active ingredients of essential oil are achieved, and the effects of improving the efficacy of essential oil and optimizing the release of aroma are achieved; by controlling the temperature fluctuation in the whole S3 step within ±0.5℃, the effects of maintaining a stable temperature environment and reducing the influence of temperature fluctuation on the active ingredients of essential oil are achieved, and the effects of improving the stability of the product and prolonging the shelf life are achieved.

[0066] Please refer to the attached Figure 1 The homogenization pressure of S4 is applied in stages:

[0067] First stage: 20-30 MPa, cycle 2 times;

[0068] Second stage: 40-50 MPa, cycle 2 times;

[0069] Third stage: 60-80 MPa, cycle 1 time.

[0070] Specifically, by homogenizing at a lower pressure of 20-30 MPa and cycling 2 times, the effects of preliminary dispersion of essential oil and reduction of large particle formation are achieved, and the basis for subsequent higher pressure homogenization is laid, and the uniformity of essential oil dispersion is improved; by homogenizing at a medium pressure of 40-50 MPa and cycling 2 times, the effects of further refining the particle size of essential oil dispersion phase and improving the uniformity of dispersion are achieved, and the compatibility of essential oil and matrix is enhanced, and the stability and uniformity of the product are improved; by homogenizing at a higher pressure of 60-80 MPa and cycling only 1 time, the effects of finally refining the particle size of essential oil dispersion phase to the required range of 50-200 nm are achieved, and the purposes of improving the dispersion stability of essential oil and optimizing the use effect of the product are achieved.

[0071] Please refer to the attached Figure 1 The programmed cooling of S5 includes the following stages:

[0072] From 45℃ to 35℃: cooling rate 0.8-1℃ / min;

[0073] From 35℃ to 25℃: cooling rate 0.5-0.7℃ / min;

[0074] 25℃ constant temperature aging stage: humidity control at 30-50% RH.

[0075] Specifically, by reducing the temperature from 45℃ to 35℃ at a rate of 0.8-1℃ / min, the product temperature is quickly reduced to reduce the decomposition of heat-sensitive components, thereby achieving the effect of protecting active ingredients in the product and improving product stability; by reducing the temperature from 35℃ to 25℃ at a slower rate of 0.5-0.7℃ / min, the temperature reduction process is carefully controlled to avoid large temperature gradients and stress in the product, thereby achieving the effect of reducing product stratification and improving product uniformity; by constant temperature aging at 25℃ and controlling the environmental humidity at 30-50% RH, the product structure and performance are optimized, while avoiding excessive humidity leading to product moisture absorption or low humidity leading to product water loss, thereby achieving the effect of improving product stability and extending shelf life.

[0076] Please refer to the attached Figure 1 The addition interval time of each essential oil component in S3 is 2-5 minutes, and after adding each component, it is stirred at a low speed of 100-200 rpm for 3 minutes.

[0077] Specifically, by setting an addition interval time of 2-5 minutes, it can be ensured that each group of essential oil has enough time to mix with the matrix after being added, reducing direct contact and possible interaction between essential oils, thereby achieving the effect of improving mixing uniformity and reducing the risk of essential oil decomposition; after adding each group of essential oil, it is stirred at a low speed of 100-200 rpm for 3 minutes, which can avoid excessive shear force leading to decomposition of essential oil components or destruction of emulsion system, while ensuring that the essential oil is fully mixed with the matrix to improve dispersion uniformity; by setting a stirring time of 3 minutes, it can ensure that the mixing between essential oil and matrix reaches a sufficient uniformity, while avoiding long-time stirring leading to volatilization loss of essential oil or excessive emulsification of the matrix.

[0078] The application of an anti-static composition containing natural jojoba oil and sweet almond oil, for the above-mentioned anti-static composition containing natural jojoba oil and sweet almond oil, the composition is mixed with water at a mass ratio of 1:30-50, and emulsified by ultrasonic for 5-10 minutes to form an emulsion; applied to the fabric by padding or spraying, the treatment temperature is 30-50℃; the liquid retention rate is controlled at 60-80% of the weight of the fabric.

[0079] Specifically, the composition is mixed with water at a mass ratio of 1:30-50, which can ensure the stability and uniformity of the emulsion while maintaining the effective concentration of the antistatic ingredients; ultrasonic emulsification is performed for 5-10 minutes, which can provide sufficient energy to break the oil droplets and form a uniform and fine emulsion, helping to improve the uniform distribution and permeability of the antistatic ingredients on the fabric; the emulsion is applied to the fabric by padding or spraying, both of which are commonly used in the industry for fabric treatment, and the appropriate method can be selected according to the specific production conditions and needs; the padding method is suitable for continuous fabric treatment production lines, while the spraying method is more suitable for local treatment or small batch production; the treatment temperature is controlled at 30-50℃, which can ensure the stability and flowability of the emulsion while avoiding excessive temperature that may cause fabric damage or decomposition of the antistatic ingredients; the liquid retention rate is controlled at 60-80% of the fabric weight, which can ensure that enough antistatic ingredients are uniformly coated on the fabric while avoiding excessive liquid that may cause the fabric to be excessively wet or affect its breathability.

[0080] The fabric includes wool products, chemical fiber blended fabrics, or non-woven fabric substrates, the padding roller pressure is 0.3-0.5 MPa, and the spraying atomization pressure is 0.2-0.4 MPa.

[0081] Specifically, for wool products, chemical fiber blended fabrics, or non-woven fabric substrates, the padding roller pressure is controlled at 0.3-0.5 MPa. This pressure range can ensure sufficient contact between the emulsion and the fabric while avoiding excessive pressure that may cause fabric deformation or damage; uniform distribution of the roller pressure during padding is very important for the consistency of the treatment effect, especially when dealing with more fragile wool products or non-woven fabrics, special attention should be paid to pressure control; for spraying application, the atomization pressure is controlled at 0.2-0.4 MPa. This pressure range can ensure uniform atomization of the emulsion, forming fine droplets that are beneficial to the uniform distribution and penetration of the emulsion on the fabric surface; the control of atomization pressure has a direct impact on the uniformity and coverage of spraying. Too low pressure may result in insufficient emulsion atomization, while too high pressure may result in large droplets that affect the uniform distribution of the emulsion on the fabric.

[0143] II. Technical effect attribution analysis

[0144] 1. Success keys of Example 1

[0145] The oil phase ratio of 1.59:1 enables the formation of eutectic structure of jojoba oil / sweet almond oil;

[0146] The gradient addition of 45 / 43 / 40℃ reduces the loss of high-volatile components;

[0147] Staged homogenization avoids local overheating leading to decomposition of essential oils.

[0148] 2. Performance advantages of Example 2

[0149] High content of sweet almond oil improves spreadability;

[0150] 80 MPa high-pressure homogenization enables particle size ≤100 nm, enhancing permeation;

[0151] Humidity of 50% RH controls the crystallization rate of beeswax.

[0152] 3. Failure sources of Example 3

[0153] Excessive jojoba oil ratio disrupts oil phase balance;

[0154] Missing program cooling leads to disordered aggregation of beeswax;

[0155] Essential oil addition temperature is too low causing local solidification.

[0156] Comparative Example 1

[0157] Component ratio (wt%):

[0158] Jojoba oil 70%, replacing sweet almond oil, grape seed oil 8.5%, beeswax 5.5%, and compound essential oil same as Example 1, total amount 10%, and deionized water to make up;

[0159] II. Preparation method:

[0160] S1: melt beeswax at 70°C for 15 min;

[0161] S2: preheat jojoba oil + grape seed oil to 58°C, add melted beeswax, stir at 400 rpm for 30 min;

[0162] S3: add essential oils as in Example 1, add by gradient;

[0163] S4 and S5: as in Example 1.

[0164] II. Optimization basis:

[0165] Verify the necessity of sweet almond oil for surface tension, its oleic acid content is > 70%, while jojoba oil is only 10%;

[0166] III. Effect verification data are shown in Table 2.

[0167] Table 2:

[0168] Test item Result Test standard Difference from Example 1 Surface tension (mN / m) 32.4 GB / T 12703.1 Increased by 22.3% Fabric wetting time (s) 15.7 GB / T 5555 Extended by 423% Electrostatic half-life (s) 2.8 GB / T 12703.1 Extended by 833%

[0169] Conclusion: technical failure mechanism caused by the absence of sweet almond oil.

[0170] 1. Insufficient oleic acid causes surface tension to rise

[0171] The absence of sweet almond oil reduces the oleic acid content of the composition to less than 5%, while Example 1 is 22%, causing the surface tension to rise from 26.5 mN / m to 32.4 mN / m, an increase of 22.3%, and further causing the spreading performance to deteriorate significantly, with the fabric soaking time extending from ≤ 3 seconds to 15.7 seconds.

[0172] 2. Microcrystalline network fracture hinders charge dissipation

[0173] The absence of sweet almond oil destroys the microcrystalline formation mechanism of beeswax, causing the charge dissipation channel to be blocked, with the static half-life extending from 0.3 seconds to 2.8 seconds, an increase of 833%, and the static control function completely failing.

[0174] Comparative Example 2

[0175] I. Technical solution:

[0176] 1. Component ratio: as in Example 1;

[0177] 2. Preparation method:

[0178] S1: melt beeswax at 80°C for 20 min;

[0179] S2: preheat oil to 80°C, stir at 600 rpm for 20 min;

[0180] S3: All essential oils were added at once at 65°C and stirred at 300 rpm for 15 min;

[0181] S4: cancel homogenization;

[0182] S5: Direct cooling to 25℃ without programmed cooling.

[0183] 2. Optimization basis:

[0184] The necessity of gradient addition, homogenization, and programmed cooling was verified by simulating small-scale workshop production conditions. III. The effect verification data is shown in Table 3 below.

[0185] Table 3:

[0186] Test item Result Test standard Difference from Example 1 Essential oil retention rate (%) 71.2 GC-MS (ISO 11024) Decreased by 27.8% Particle size distribution (D90, pm) 8.0 ISO 13320 Increased by 3900% Storage stability at 40°C 7-day oil-water separation GB / T 29665 Failed Antibacterial rate (%) 85.4 GB / T 20944.3 Decreased by 13.9%

[0187] Conclusion: Process defects lead to triple technical failures:

[0188] 1. Heat-sensitive essential oil decomposition at high temperature

[0189] The high temperature environment of 80℃ causes chemical decomposition of heat-sensitive essential oils, among which the volatilization loss rate of limonene reaches 46.8%, and the content of terpinen-4-ol, the active ingredient of tea tree essential oil, drops from 35% to 28%.

[0190] 2. Lack of homogeneity leads to the collapse of the dispersed system

[0191] Eliminating the high-pressure homogenization step resulted in uneven dispersion of the essential oil, with the particle size distribution D90 value increasing from 0.2 μm to 8.0 μm, an increase of 3900%, which impaired the release of functional ingredients.

[0192] 3. Rapid cooling induces crystal coarsening

[0193] The direct cooling solidification method causes the beeswax crystallization rate to be out of control, resulting in disorder of the microcrystalline network structure.

[0194] 4. The synergistic effect of triple failure resulted in: essential oil retention rate decreased by 27.8% and antibacterial efficacy decreased by 13.9%.

[0195] Comparative Example 3

[0196] 1. Technical solution:

[0197] 1. Current market composition ratio (wt%):

[0198] Jojoba oil 30%, amino-modified silicone oil 15%, sodium lauryl sulfate 5%, grape seed oil 10%, deionized water 40%;

[0199] 2. Preparation method:

[0200] All components were mixed at 70℃ once, stirred at 600rpm for 30min;

[0201] Filling after cooling to 25℃;

[0202] II. Optimization according to:

[0203] Select the closest prior art, containing silicone oil and ionic surfactant

[0204] III. Effect verification data as shown in Table 4:

[0205] Table 4:

[0206] Test item Result Test standard Difference from Example 1 Patch test irritability Grade 2 ISO 10993-10 Severity increased by 200% 28-day biodegradation rate (%) 41.3 OECD 301B Decreased by 55.2% Fabric air permeability loss rate (%) 18.7 GB / T 5453 Increased by 484% Surface resistance after 20 washes <![CDATA[3.2×10 13 Oh]]> AATCC 76 Increased by >4 orders of magnitude

[0207] Conclusion: There are three fundamental defects in the prior art:

[0208] 1. Silicone oil film blocks the fabric air permeation channel

[0209] Amino-modified silicone oil forms a continuous film layer on the fabric surface, blocking the fiber pores, resulting in a high air permeability loss rate of 18.7%.

[0210] 2. Ionic emulsifier elution rate out of control

[0211] Sodium dodecyl sulfate ionic emulsifier elutes rapidly during washing, and after 20 standard washes, the surface resistance increases by more than 4 orders of magnitude, from 101 0 Ω level to 1013Ω level, completely losing wash resistance.

[0212] 3. Synthetic components cause biological toxicity

[0213] Silicone oil and ionic emulsifier are difficult to biodegrade, with a 28-day biodegradation rate of only 41.3%, lower than the environmental protection requirement of 60%, and the patch test shows moderate skin irritation.

[0214] 4. The essence of the defect is that synthetic silicone oil and ionic surfactant violate the principles of green chemistry, and there are irreconcilable technical contradictions in the three dimensions of safety, durability and environmental protection.

[0215] Although embodiments of the present application have been shown and described, it will be understood by those having ordinary skill in the art that various changes, modifications, substitutions and alterations can be made thereto without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
