Description

Technical Field

[0001] This invention relates to the field of color developer technology, specifically to a temperature-responsive color developer composition and its application, and more particularly to a color developer composition that exhibits color development effect below 20°C or above 35°C. Background Technology

[0002] Surfactants (hereinafter referred to as surfactants) are substances that can significantly reduce interfacial tension, typically containing a polar hydrophilic head group and a nonpolar hydrophobic tail chain. When the concentration of surfactants in water reaches the critical micelle concentration (CMC), they can self-assemble into aggregates with different structures, such as inverse micelles, inverse hexagonal liquid crystals, inverse bicontinuous phase cubic liquid crystals, lamellar liquid crystals, bicontinuous phase cubic liquid crystals, hexagonal liquid crystals, and micelles, from low to high IOB concentrations. These aggregates have many applications in the pharmaceutical and daily chemical industries. In lamellar liquid crystals, the super-swollen lamellar phase formed by the self-assembly of low-concentration surfactants in water has an attractive iridescent appearance, which can stimulate consumer desire when used in cosmetics (patent CN 119564525A), but its application is currently rare.

[0040] In a specific embodiment of the present invention, the specific method for conducting performance testing is as follows: 1) Evaluation of color rendering effect At the color development temperature, the color development effect of the compositions prepared in each example and comparative example was visually evaluated in a dark room with a single light source and a fixed direct illumination angle, according to the following criteria.

[0041] Qualified (Excellent) ◎: High transparency, excellent color rendering, and obvious iridescent color.

[0042] Acceptable (Good) ○: There is some turbidity, but the color development is good; or there is no turbidity at all, but the color development is weak.

[0043] Unqualified (slightly worse) △: There is some turbidity and the color development is weak.

[0044] Unacceptable (Very Poor) ×: Severe turbidity, almost no color development; or no color development at all.

[0045] 2) Determination of colorimetric temperature range In the color development methods of the following embodiments, a mercury thermometer is used to test and record the complete color development temperature range of the mixture in real time during the cooling process.

[0046] 3) Determination of layered phases The layered phase structure formed by surfactant self-assembly exhibits anisotropy and displays unique birefringent optical properties under crossed polarized light. This property allows for a quick and intuitive determination of the formation of the layered phase. The specific steps are as follows: place the composition between two mutually orthogonal polarizers A and B (e.g., ...). Figure 1 (As shown); place an incandescent light source on one side of the polarizer; then observe the composition from the other side.

[0047] The formation of layered phases is determined based on the following criteria: Layered phase formation: Birefringent optical properties were observed using crossed polarizers; Layered phase not formed ×: No birefringent optical properties were observed through the crossed polarizer.

[0048] 4) Determination of super-bentonized lamellar phase Arai, Yuto et al. on "Thermomodulated Structure Coloring of Water / Surfactant / Oil Emulsions" Langmuir As mentioned in 38(2021): 569-575), when light passes through a sample with a super-swelled layered structure and undergoes multilayer interference, the incident light angle θ and the reflected light wavelength... The relationship between the interlayer spacing d and the refractive index n of the sample satisfies the Bragg-Snell equation (Equation 1).

[0049] (1) According to the Bragg-Snell equation, sin²θ and λ² are linearly related. Reflectance spectra in the range of 400 to 800 nm were collected using an angle-resolved spectrometer (Shanghai Haoliang Optoelectronic Equipment Co., Ltd., ARS macroscopic angle-resolved spectrometer) when the incident light angle varied from 20° to 60°. Linear regression fitting was performed on the experimental data, and the interlayer spacing was calculated using the slope method. The interlayer spacing of the super-bulked layered phase is in the hundreds of nanometers, while the interlayer spacing of conventional layered structures generally does not exceed 100 nm. Other microscopic results cannot be effectively measured using this method. Therefore, the formation of the super-bulked layered phase is determined based on the following criteria: Interlayer spacing ≥100nm: formation of super-swelled lamellar phase.

[0050] Interlayer spacing < 100 nm or no linear relationship between sin²θ and λ²: super-bulky lamellar phase not formed.

[0051] 5) Calculation of the Inorganic-Organic Balance Value (hereinafter referred to as the IOB value) In *Fundamentals and Applications of Organic Concept Maps* (published in 1984, by Yoshio Koda et al.), the covalently bonded portion of an organic compound, i.e., the nonpolar portion, is considered organic, and the degree of organicity is differentiated according to the number of carbon atoms, expressed numerically as the organic value (hereinafter referred to as the OV value). The electrostatically bonded portion of an organic compound, i.e., the polar portion, is considered inorganic, and the degree of polarity is expressed numerically as the inorganic value (hereinafter referred to as the IV value). The IOB value is calculated by the ratio of the IV value to the OV value (Equation 2) and is used to characterize the overall polarity (hydrophilicity) of the compound molecule.

[0052] IOB = IV / OV (2) For example, the OV value of each carbon atom in the molecule is 20; the IV value of the ether bond is 20, the IV value of the carboxyl group is 150, the IV value of the hydroxyl group is 100, etc. Other specific OV and IV value reference values ​​are shown in Table 1.

[0053] Based on the above method, the IOB values ​​of each raw material in this invention were calculated.

[0054] Table 1: IV and OV values ​​for different functional groups Examples 1-6 and Comparative Examples 1-3 Examples 1-6 and Comparative Examples 1-3 provide a color-developing composition comprising: component a): fatty alcohol polyether; component c): Gemini anionic surfactant.

[0055] The color development method of the color-developing composition is as follows: Weigh each component according to the type and weight of each component in Table 2. Preheat components a), c), and water in an 85°C water bath. Then, add the preheated components a) and c) to the preheated water in an 85°C water bath and stir for at least 5 minutes using a high-speed stirrer at 200-800 rpm. Finally, cool the resulting mixture to the color development temperature in ambient air.

[0056] Table 2 The results of measuring the color development temperature range, evaluating the color development effect, and determining the lamellar phase of the colorimetric compositions prepared in Examples 1-6 and Comparative Examples 1-3 are shown in Table 2. Colorimetric photographs of the colorimetric compositions prepared in Examples 1-6 and Comparative Examples 1-3 are shown below. Figure 2 As shown, the top images are front-view photographs, and the bottom images are top-view photographs. The layered phase photographs observed using crossed polarizers of the colorimetric compositions prepared in Examples 4-6 and Comparative Examples 2-3 are shown below. Figure 3 As shown, the colorimetric compositions prepared in Examples 4-6 and Comparative Example 2 all exhibited birefringent optical properties, while Comparative Example 3 did not exhibit birefringent optical properties.

[0057] From Table 2 and Figure 2 The results show that the color-developing compositions prepared in Examples 1-6 can all develop color at temperatures above 35°C, exhibiting a high-temperature color-developing effect, and a layered phase is formed. In contrast, the color-developing compositions prepared in Comparative Examples 1 and 3 show no color development and do not possess a color-developing effect. While the color-developing composition prepared in Comparative Example 2 shows color development at high temperatures, its color development is weak and exhibits some turbidity, indicating that the color-developing effect is still unsatisfactory. Further comparison of the results of Examples 1-3 with Comparative Example 1 shows that when the IOB value of the fatty alcohol polyether used is between 0.75 and 0.86, a satisfactory high-temperature color-developing effect can be obtained; however, if the IOB value is too high, color development is impossible. Comparison of the results of Examples 1, 4-6 with Comparative Examples 2-3 shows that when the weight fraction of component a) is between 1.2 and 2.5 parts, a satisfactory high-temperature color-developing effect can be obtained; otherwise, the color-developing effect deteriorates.

[0058] Examples 7-15 and Comparative Examples 4-6 Examples 7-15 and Comparative Examples 4-6 provide a color-developing composition comprising: component a): fatty alcohol polyether; component c): at least one of anionic surfactant, cationic surfactant, and amphoteric surfactant.

[0059] The color development method of the color development composition is the same as that in Examples 1-6 above, except that each component is weighed according to the type and weight of each component in Tables 3 and 4.

[0060] Table 3 Table 4 The results of measuring the color development temperature range, evaluating the color development effect, and determining the lamellar phase of the color-developing compositions prepared in Examples 7-15 and Comparative Examples 4-6 are shown in Tables 3 and 4. The color development temperature range is defined as "≥35℃", indicating that the composition can develop color within a certain temperature range above 35℃. Color development photographs (front view) of the color-developing compositions prepared in Examples 7-15 and Comparative Examples 4-6 are shown below. Figure 4 As shown.

[0061] From Table 3-4 and Figure 4 The results show that the color-developing compositions prepared in Examples 7-15 can all develop color at temperatures above 35°C, exhibiting a high-temperature color-developing effect, and a layered phase is formed. In contrast, the color-developing compositions prepared in Comparative Examples 4 and 6 show no color development and do not possess a color-developing effect. Although the color-developing composition prepared in Comparative Example 5 exhibits color development at high temperatures, its color development is weak and exhibits some turbidity, indicating that the color-developing effect is still unqualified. A comparison of the results of Examples 7-10 and Comparative Example 4 in Table 3 shows that when component c) is the amphoteric surfactant cocamidopropyl betaine, a color-developing effect cannot be obtained. A comparison of the results of Examples 11-15 and Comparative Examples 5-6 in Table 4 shows that when the weight fraction of component c) is 0.0014-0.007 parts, a qualified high-temperature color-developing effect can be obtained; outside this range, the color-developing effect deteriorates. Furthermore, when the weight fraction of component c) is 0.0015-0.005 parts, the resulting composition exhibits the best color-developing effect.

[0062] Examples 16-36 and Comparative Examples 7-11 Examples 16-36 and Comparative Examples 7-11 provide a color-developing composition comprising: component a): fatty alcohol polyether; component b): at least one of ternary or higher polyol fatty acid esters, fatty glycerol ethers, and cyclic alcohol ethers; and component c): Gemini anionic surfactant.

[0063] The color development method of the color-developing composition is as follows: Weigh each component according to the type and weight of each component in Table 5-8. Preheat components a), b), c), and water separately in an 85℃ water bath. Then, add the preheated components a), b), and c) to the preheated water in an 85℃ water bath and stir for at least 5 minutes using a high-speed stirrer at a speed of 200-800 rpm. Finally, cool the resulting mixture to the color development temperature in ambient air while stirring.

[0064] Table 5 Table 6 Table 7 Table 8 The results of measuring the color development temperature range, evaluating the color development effect, and determining the lamellar phase of the colorimetric compositions prepared in Examples 16-36 and Comparative Examples 7-11 are shown in Tables 5-8. Colorimetric photographs of the colorimetric compositions prepared in Examples 16-36 and Comparative Examples 7-11 are shown below. Figure 5 , Figure 6 , Figure 7 As shown, the top images are front-view photos, and the bottom images are top-view photos.

[0065] From Table 5-8 and Figure 5-7 The results show that the color-developing compositions prepared in Examples 16-36 can all develop color at temperatures above 35°C, exhibiting a high-temperature color-developing effect, and a layered phase is formed. In contrast, the color-developing compositions prepared in Comparative Examples 7, 9, and 11 show no color development and do not possess a color-developing effect. While the color-developing compositions prepared in Comparative Examples 8 and 10 show color development at high temperatures, the color development is weak and exhibits some turbidity, resulting in an unsatisfactory color-developing effect. A comparison of the results of Examples 16-28 with Comparative Example 7 in Tables 5 and 6 shows that when the overall IOB values ​​of components a) and b) are between 0.67 and 1.0, a satisfactory high-temperature color-developing effect can be obtained; however, if the IOB value is too high, color development is impossible. Furthermore, the color-developing effect is best when the overall IOB values ​​of components a) and b) are between 0.74 and 0.85. A comparison of the results of Examples 29-31 and Comparative Examples 8-9 in Table 7 shows that when component b) is an aliphatic glycerol ether, a satisfactory high-temperature color development effect can be obtained when the total weight parts of components a) and b) are between 1.2 and 2.5 parts; otherwise, the color development effect will be poor. A comparison of the results of Examples 32-36 and Comparative Examples 10-11 in Table 8 shows that when component b) is a cyclic alcohol ether, a satisfactory high-temperature color development effect can be obtained when the total weight parts of components a) and b) are between 1.2 and 3.0 parts; otherwise, the color development effect will be poor.

[0066] Examples 37-46 and Comparative Examples 12-14 Examples 37-46 and Comparative Examples 12-14 provide a color-developing composition comprising: component a): fatty alcohol polyether; component b): at least one of ternary or higher polyol fatty acid esters, fatty glycerol ethers, and cyclic alcohol ethers; and component c): at least one of anionic surfactants and cationic surfactants.

[0067] The color development method of the color development composition is the same as that in Examples 16-36 above, except that each component is weighed according to the type and weight of each component in Tables 9 and 10.

[0068] Table 9 Table 10 The results of measuring the colorimetric temperature range, evaluating the colorimetric effect, and determining the lamellar phase of the colorimetric compositions prepared in Examples 37-46 and Comparative Examples 12-14 are shown in Tables 9 and 10. The colorimetric temperature range is defined as "≥35℃", indicating that the composition can develop color within a certain temperature range above 35℃. Colorimetric photographs (front view) of the colorimetric compositions prepared in Examples 37-46 and Comparative Examples 12-14 are shown below. Figure 8 As shown.

[0069] From Table 9-10 and Figure 8 The results show that the color-developing compositions prepared in Examples 37-46 can all develop color at temperatures above 35°C, exhibiting a high-temperature color-developing effect, and a layered phase is formed. However, the color-developing compositions prepared in Comparative Examples 12 and 14 show no color development and do not possess a color-developing effect. Although the color-developing composition prepared in Comparative Example 13 shows color development at high temperatures, its color development is weak and exhibits some turbidity, indicating that the color-developing effect is still unqualified. A comparison of the results of Examples 37-41 and Comparative Example 12 in Table 9 shows that when component c) is the amphoteric surfactant cocamidopropyl betaine, a color-developing effect cannot be obtained. A comparison of the results of Examples 42-46 and Comparative Examples 13-14 in Table 10 shows that when the weight fraction of component c) is 0.0014-0.01 parts, a qualified high-temperature color-developing effect can be obtained; however, outside this range, the color-developing effect deteriorates. Furthermore, the composition exhibits the best color development effect when the weight of component c) is 0.0015-0.005 parts.

[0070] Examples 47-56 and Comparative Examples 15-18 Examples 47-56 and Comparative Examples 15-18 provide a color-developing composition comprising: component a): fatty alcohol polyether; component b): at least one of diol fatty acid ester and ethylhexylglycerin; component c): Gemini anionic surfactant.

[0071] The color development method of the color-developing composition is as follows: Weigh each component according to the type and weight of each component in Tables 11 and 12. Preheat the mixture 1 formed by components a) and b) in an 85°C water bath, as well as the mixture 2 formed by preheating component c) and water. Then, add the preheated mixture 1 to the preheated mixture 2 in an 85°C water bath and stir at 200-800 rpm for at least 5 minutes. Then, stir and cool the resulting mixture in ambient air and in an ice-water bath until it reaches the color development temperature.

[0072] Table 11 Table 12 The results of measuring the color development temperature range, evaluating the color development effect, and determining the lamellar phase of the colorimetric compositions prepared in Examples 47-56 and Comparative Examples 15-18 are shown in Tables 11 and 12. Figure 9 As shown, the top images are front-view photographs, and the bottom images are top-view photographs. The layered phase photographs observed using crossed polarizers of the colorimetric compositions prepared in Examples 50, 54-55, and Comparative Examples 17-18 are shown below. Figure 10 As shown, the colorimetric compositions prepared in Examples 50, 54-55, and Comparative Example 17 all exhibited birefringent optical properties, while Comparative Example 18 did not. The colorimetric composition of Example 50 was also subjected to angle-resolved spectroscopy to determine the super-swelled lamellar phase; the test results are shown below. Figure 11 As shown. By Figure 11 A obtained the reflected light wavelengths at different incident angles, and the sin 2 θ and λ 2 A linear relationship was fitted, and the results are as follows: Figure 11 As shown in B, the results indicate that sin 2 θ-λ 2 There is a good linear relationship (R) 2 =0.99999), and further calculated by Equation 1, the interlayer spacing of the lamellar phase in Example 50 is 230.38 nm ≥ 100 nm, which proves that it forms a super-swelled lamellar phase.

[0073] From Table 11-12 and Figure 9The results show that the color-developing compositions prepared in Examples 47-56 can all develop color at temperatures below 20°C, exhibiting a low-temperature color-developing effect, and a layered phase is formed. However, the color-developing compositions prepared in Comparative Examples 15, 16, and 18 show no color development and do not possess a color-developing effect. Although the color-developing composition prepared in Comparative Example 17 shows color development at low temperatures, its color development is weak and exhibits some turbidity, indicating that the color-developing effect is still unqualified. A comparison of the results of Examples 47-53 and Comparative Examples 15-16 in Table 11 shows that when component a) is lauryl ether-7, a color-developing effect cannot be obtained. Furthermore, when the IOB value is between 0.64 and 0.88, a qualified low-temperature color-developing effect can be obtained; however, when the IOB value is too high, color development is impossible. Even further, when the overall IOB value of components a) and b) is between 0.66 and 0.88, the color-developing effect is the best. As can be seen from the comparison of the results of Examples 54-56 and Comparative Examples 17-18 in Table 12, when the total weight of components a) and b) is between 1.2 and 2.5 parts, a qualified low-temperature color development effect can be obtained; when it is outside this range, the color development effect will be worse.

[0074] Examples 57-64 and Comparative Examples 19-21 Examples 57-64 and Comparative Examples 19-21 provide a color-developing composition comprising: component a): fatty alcohol polyether; component b): at least one of diol fatty acid ester and ethylhexylglycerin; component c): at least one of anionic surfactant and cationic surfactant.

[0075] The color development method of the color-developing composition is the same as that in Examples 47-56 above, except that each component is weighed according to the type and weight of each component in Tables 13 and 14.

[0076] Table 13 Table 14 The results of measuring the colorimetric temperature range, evaluating the colorimetric effect, and determining the lamellar phase of the colorimetric compositions prepared in Examples 57-64 and Comparative Examples 19-21 are shown in Tables 13 and 14. The colorimetric temperature range is defined as "≤20℃," indicating that the composition can develop color within a certain temperature range below 20℃. Colorimetric photographs (front view) of the colorimetric compositions prepared in Examples 57-64 and Comparative Examples 19-21 are shown below. Figure 12 As shown.

[0077] From Table 13-14 and Figure 12The results show that the color-developing compositions prepared in Examples 57-64 can all develop color at temperatures below 20°C, exhibiting a low-temperature color-developing effect, and a layered phase is formed. However, the color-developing compositions prepared in Comparative Examples 19-21 show no color development and do not possess a color-developing effect. A comparison of the results of Examples 62-64 and Comparative Example 21 in Table 14 shows that when component c) is cocamidopropyl betaine, a color-developing effect cannot be obtained. A comparison of the results of Examples 57-61 and Comparative Examples 19-20 in Table 13 shows that when the weight fraction of component c) is 0.0006-0.036 parts, a satisfactory high-temperature color-developing effect can be obtained; outside this range, the color-developing effect deteriorates. Furthermore, when the weight fraction of component c) is 0.001-0.03 parts, the resulting composition exhibits the best color-developing effect.

[0078] Application Examples 1-5 Application Examples 1-5 provide a high-temperature washing and care product prepared based on the color-developing composition of the present invention, to evaluate its color-developing effect when mixed with other ingredients in the washing and care product. The specific components and weight proportions of the washing and care product are shown in Table 15.

[0079] The preparation method and color development method of the high-temperature washing and care products are as follows: Weigh each component according to the weight fractions of components a), b), c) and other ingredients in Table 15, stir and heat them in an 85℃ water bath until they are evenly mixed, and then use a high-speed stirrer at a speed of 200-800 rpm to stir and cool them to room temperature in ambient air to obtain high-temperature washing and care products.

[0080] When using, weigh out the hot water (temperature ≥35℃) according to the weight proportions of water in Table 15, then shake and mix the hot water with the high-temperature washing and care products until the color develops.

[0081] Application Example 6 Example 6 of this application provides a temperature indicator liquid prepared based on the colorimetric composition of the present invention. The specific components and weight parts of the temperature indicator liquid are shown in Table 15.

[0082] The preparation method and color development method of the temperature indicating liquid are as follows: Weigh each component according to the type and weight proportions in Table 15. Preheat components a), b), c), other components, and water separately in an 85°C water bath. Then, add the preheated components a), b), c), and other components to the water in an 85°C water bath, and stir for at least 5 minutes using a high-speed stirrer at 200-800 rpm. Next, cool the resulting mixture to room temperature in ambient air while stirring. This yields the temperature indicating liquid. The temperature indicating liquid will show color when the ambient temperature is above 35°C, indicating an ambient temperature above 35°C; otherwise, it will not show color.

[0083] Application Example 7 This application example 7 provides a low-temperature landscape liquid prepared based on the color-developing composition of the present invention. The specific components and weight parts of the low-temperature landscape liquid are shown in Table 15.

[0084] The preparation method of the low-temperature landscape liquid is the same as that in Application Example 6. It develops color when the ambient temperature is below 20°C and can be used as an iridescent landscape liquid under low-temperature conditions.

[0085] Table 15 The results of measuring the color development temperature range, evaluating the color development effect, and determining the lamellar phase of the mixtures of washing and care products prepared in Application Examples 1-5 and hot water, the temperature indicator liquid prepared in Application Example 6, and the low-temperature landscape liquid prepared in Application Example 7 are shown in Table 15. Color development photographs are also shown. Figure 13 As shown, the top images are front-view photographs, and the bottom images are top-view photographs. (From Table 15 and...) Figure 13 The results show that the color-developing composition prepared in this invention can maintain its color development effect at the corresponding color-developing temperature when applied to high-temperature washing and care products, temperature indicator liquids, and low-temperature landscape liquids. This indicates that the color-developing composition of this invention has excellent and stable color-developing performance, unaffected by other components.

[0086] In summary, the color-developing composition prepared by the present invention using specific components exhibits significant color-developing effects below 20°C (low-temperature color development) or above 35°C (high-temperature color development). The low-temperature color-developing composition can be applied to, but is not limited to, the following products: such as the low-temperature landscape liquid used in Example 7; or a highly nutritious essence requiring refrigeration, which displays an iridescent appearance in low-temperature environments, disappearing at higher temperatures to remind consumers to refrigerate.
