Description

Technical Field

[0001] The invention relates to the technical field of daily chemical industry, in particular to a fragrance light stabilizer and a liquid detergent composition with excellent fragrance stability using the same. Background Art

[0002] The appeal of fragrance comes from people's pursuit of beautiful things. Different fragrances can evoke different emotional memories in people. For example, the fragrance of flowers reminds people of the breath of spring, while the fragrance of fruits makes people feel the freshness of summer. Therefore, when consumers choose daily chemical products, they are often attracted by those fragrances that can resonate. These pleasant smells not only make people feel happy when using the products, but also add a beautiful atmosphere to daily life. It is a manifestation of people's pursuit of quality and enjoyment of life. Therefore, in detergent products, fragrances that provide consumers with a pleasant sensory experience can directly affect the market competitiveness of products.

[0003] Detergent products packaged in transparent containers are more likely to change in fragrance than those packaged in opaque containers, which may be caused by light irradiation. Ultraviolet light and the higher energy parts of visible light may cause certain components in the fragrance to be unstable. The chemical structures in the fragrance that are sensitive to irradiation include unsaturated bonds, atoms such as sulfur and nitrogen, and special cyclic chemical structures. The above structures are prone to enter an excited state under ultraviolet irradiation, and then undergo chemical structure changes, which may further affect the stability of other fragrance raw materials, and ultimately lead to significant changes in the fragrance and appearance of the detergent. These negative effects greatly reduce consumers' willingness to buy and are not conducive to the brand's reputation.

[0004] At present, there are some solutions in the industry: for example, adding antioxidants such as tert-butyl parabiphenol (TBHQ), ascorbic acid, etc. to detergents; or adding reducing agents such as sodium thiosulfate, sodium sulfite, etc. However, these solutions cannot completely solve this technical problem and may even cause other derivative problems. For example, reducing agents may affect the stability of isothiazolinone preservatives, some antioxidants may have poor stability and are difficult to pass accelerated aging tests, and some antioxidants may increase the irritation of detergents.

[0005] Therefore, there is an urgent need to develop a detergent composition with enhanced fragrance stability, which can withstand ultraviolet radiation or high temperature treatment while maintaining its own properties (appearance, smell) unchanged, while being mild and non-irritating, giving consumers a good usage experience and sense of security. Summary of the invention

[0118] The performance test methods involved in the liquid detergent composition of this application are as follows:

[0119] Ultraviolet radiation absorption rate △A

[0120] The liquid detergent composition of the present invention comprises a surfactant, a fragrance light stabilizer, a fragrance, an adjuvant, and a solvent, and has enhanced ultraviolet radiation absorption performance. The term "enhanced ultraviolet radiation absorption performance" means that the ultraviolet radiation absorption rate ΔA in the 320 to 400 nm band is greater than or equal to 20%.

[0121] The ultraviolet radiation absorbance ΔA was tested using a Shimadzu UV-2450 UV-visible spectrophotometer. The sample test concentration was 5%, and the solvent was pure water. The test wavelength range was 320 to 400 nm. The sample was a liquid detergent composition with a fragrance light stabilizer added, and the control was a liquid detergent composition without a fragrance light stabilizer added. There was no difference between the sample and the control except for the fragrance light stabilizer.

[0122] The ultraviolet radiation absorption rate △A is calculated as follows:

[0123]

[0124] f0: the maximum absorbance of the reference substance in the ultraviolet range of 320 to 400 nm, unitless;

[0125] f m : The maximum absorbance of the sample in the ultraviolet range of 320 to 400nm, unitless.

[0126] Stable performance

[0127] The liquid detergent composition of the present invention has good fragrance stability and appearance stability. Specifically, after the detergent composition undergoes ultraviolet radiation accelerated aging treatment and high temperature accelerated aging treatment, its fragrance type and fragrance intensity can be maintained stable, no new odor is generated, the appearance is a homogeneous system, and the color is basically unchanged.

[0128] Test methods for fragrance stability

[0129] The fragrance stability performance of the present invention includes two aspects: fragrance type and fragrance intensity. The test steps are as follows: the detergent composition is placed in a culture dish with a diameter of 9 cm, completely covering the bottom of the culture dish, and the liquid level is about 0.5 cm to 0.7 cm. An expert panel is used to evaluate the difference in odor before and after accelerated aging treatment. The expert panel is composed of 7 people with a keen sense of smell who have undergone professional training and grade the above performance according to Table 1 and Table 2. The accelerated aging treatment steps are described in detail below.

[0130] When conducting the fragrance grade evaluation experiment, each sample needs to be repeated three times. If two of the three experiments have the same results, the experiment is valid, and the grades of these two results are reported, and the result with the smaller number of people is reported as the number of experts. If no two of the three experiments have the same results, the experiment is invalid and needs to be repeated. Example 1: If the fragrance stability performance of sample A before and after accelerated aging is evaluated, the result of the first parallel experiment is that 6 people think that the fragrance has not changed significantly before and after accelerated aging, and the grade is good; the result of the second parallel experiment is that 7 people think that the fragrance has not changed significantly before and after accelerated aging, and the grade is good; the result of the third parallel experiment is that 5 people think that the fragrance has not changed significantly before and after accelerated aging, and the grade is general; then the experimental results are judged to be valid, the fragrance stability performance grade of sample A is "good", and the number of experts who think that the fragrance has not changed significantly before and after accelerated aging is 6. Example 2: If the fragrance stability performance of sample A before and after accelerated aging is evaluated, the result of the first parallel experiment is that 6 people think that the fragrance has not changed significantly before and after accelerated aging, and the grade is good; the result of the second parallel experiment is that 4 people think that the fragrance has not changed significantly before and after accelerated aging, and the grade is fair; the result of the third parallel experiment is that 2 people think that the fragrance has not changed significantly before and after accelerated aging, and the grade is poor; then the experimental results are judged to be invalid and the experiment needs to be repeated.

[0131] When conducting the fragrance intensity rating test, the operation method of the experimental results is the same as the above-mentioned fragrance rating test.

[0132] Table 1 Evaluation criteria for fragrance of detergent composition after accelerated aging treatment

[0133]

[0134] Table 2 Evaluation criteria for fragrance intensity of detergent compositions after accelerated aging treatment

[0135]

[0136] As shown in Table 3, the results of Table 1 and Table 2 are combined to evaluate the fragrance stability performance of the samples. The fragrance stability performance is divided into three levels: "good", "average", and "poor". Among them, the fragrance grade is a very important indicator affecting the fragrance stability performance.

[0137] Table 3 Evaluation criteria for the fragrance stability of detergent compositions after accelerated aging treatment

[0138]

[0139] Test method for appearance stability performance

[0140] The appearance of the liquid detergent composition after the accelerated aging treatment was evaluated by visual inspection, and the liquid detergent composition before the accelerated aging treatment was used as a control. The appearance stability performance was divided into three grades: "good", "average", and "poor". The appearance stability performance was evaluated according to Table 4.

[0141] Table 4 Evaluation level of appearance stability performance

[0142] Sample appearance Appearance stability performance level After accelerated aging treatment, the sample has a homogeneous appearance and the color remains basically unchanged. good The color of the sample after accelerated aging treatment has slightly changed compared to before accelerated aging. generally After accelerated aging treatment, the sample shows obvious color change or turbidity Difference

[0143] Accelerated aging treatment

[0144] The aging treatment described in the present invention includes two parts: ultraviolet radiation aging treatment and high temperature aging treatment. The terms aging treatment, aging experiment, and accelerated aging treatment are not distinguished.

[0145] High temperature aging treatment

[0146] The high temperature aging treatment of the present invention refers to placing the detergent composition in a sealed PE bottle and then storing it for four weeks at 45° C. and 70% to 80% relative humidity.

[0147] UV radiation aging treatment

[0148] The ultraviolet radiation aging treatment of the present invention refers to placing the liquid detergent composition in a sealed PE bottle and then performing light aging treatment in a xenon lamp aging test box for 24 hours. The test conditions of the xenon lamp aging test box are: light source wavelength 420nm; irradiation intensity 1.1W / m 2 ; Test temperature 50°C; Blowing temperature 40°C; Relative humidity 50%. No distinction is made between the terms UV aging and radiation aging.

[0149] Evaluation of the stability performance rating of liquid detergent compositions

[0150] The stability performance of the liquid detergent composition is graded and evaluated according to the following Tables 5 to 7. It can be seen that good stability performance means that the detergent composition can maintain stable fragrance and fragrance intensity after undergoing ultraviolet radiation accelerated aging treatment and high temperature accelerated aging treatment, without generating new odor, and the appearance is a homogeneous system with basically unchanged color.

[0156]

[0157] Test method for skin irritation of detergents

[0158] The present invention uses a zein test to evaluate the irritation of detergents to the skin. Zein is similar to the protein structure in human skin and hair. After interacting with detergents, the spatial conformation changes, thereby changing the water solubility of zein, and its water solubility increases. The content of zein dissolved in the aqueous solution is proportional to the skin irritation caused by it.

[0159] The test steps are as follows: (1) Prepare a 5% aqueous solution of the sample to be tested. (2) Add corn protein to the solution to be tested under stirring at room temperature and stir with a magnetic stirrer for about 4 hours. (3) Centrifuge the solution at 4000 rpm for 15 minutes and take the supernatant. (4) Use the kit from Thermo Fisher Scientific (Pierce TM The protein concentration C of the sample was tested using BCA Protein Assay Kit. The ZEIN value (mgN / 100mL) was calculated based on the nitrogen content of 16% in the protein.

[0160] ZEIN=C×16

[0161] The higher the protein concentration C, the higher the ZEIN value, indicating that the sample is more irritating. The irritation of the detergent samples was graded according to Table 8 below.

[0162] Table 8 Evaluation level of detergent irritation to skin

[0163] ZEIN value Skin irritation level <200 Gentle and non-irritating 200～400 Moderate stimulation >400 Strong stimulation

[0203] Table 9 Examples and Comparative Examples Related to Fragrance Composition

[0204]

[0205] Method for preparing liquid detergent composition

[0206] 1) First add deionized water into the batching pot;

[0207] 2) Raise the temperature to 50 to 60°C, use sodium hydroxide to convert linear alkylbenzene sulfonic acid and fatty acid into corresponding salts under alkaline conditions, and stir until completely dissolved;

[0208] 3) Remove the heat source, wait until the temperature drops below 50°C, add other surfactants, polymers, and chelating agents in sequence and stir until dissolved;

[0209] 4) Add the flavor light stabilizer to the flavor in a small pot, fully disperse and dissolve it. If necessary, heat it in a 60℃ water bath to promote the dissolution of the flavor light stabilizer;

[0210] 5) Add flavor, flavor light stabilizer mixture, and other additives to the batching pot in sequence and disperse them fully. Add acid-base regulator to adjust the pH value;

[0211] 6) Add preservatives, fully disperse, and discharge after passing the test.

[0212] According to the above preparation method, the liquid detergent compositions of Examples 1 to 6 were prepared, and the specific compositions are shown in Table 10.

[0213] Table 10 Composition of liquid detergent compositions of Examples 1 to 6

[0214]

[0215] The liquid detergent compositions of Examples 7 to 16 and Comparative Examples 1 to 20 were prepared according to the above preparation method, and the differences are clearly marked in Table 11.

[0216] Table 11 Similarities and differences between the liquid detergent compositions of Examples 7 to 16 and Comparative Examples 1 to 20

[0217]

[0218]

[0219] The ultraviolet radiation absorption rate test was performed on the liquid detergent compositions of Examples 1 to 16 and Comparative Examples 1 to 20 using the same method as described above. The results are shown in Table 12.

[0220] Table 12 Ultraviolet radiation absorption rate of liquid detergent compositions of Examples 1 to 16 and Comparative Examples 1 to 20

[0221]

[0222]

[0223] The ultraviolet radiation absorption rates of the liquid detergent compositions of Examples 1 to 16 and Comparative Examples 5, 8, 10, 11, 18, 19 and 20 are all greater than 20%. The fragrance light stabilizers used, including drometrizole trisiloxane, diethylaminohydroxybenzoyl hexyl benzoate and butyl methoxydibenzoylmethane, meet the technical requirements of the present invention. The fragrance light stabilizers, including methylene bis-benzotriazolyl tetramethylbutylphenol, bis-ethylhexyloxyphenol methoxyphenyl triazine, 2,2'-dihydroxy-4-methoxybenzophenone and dibenzoylmethane, which do not meet the technical invention scheme of the present invention, also have ultraviolet radiation absorption rates greater than 20% of the liquid detergent compositions.

[0224] The fragrance light stabilizers used in Comparative Examples 1-4, 6, 7, 9, and 12-17 do not meet the technical requirements of the present invention, and the ultraviolet radiation absorption rate of the liquid detergent composition thereof is less than 20%.

[0225] Examples 1 to 16 and Comparative Examples 1 to 20 were subjected to ultraviolet radiation aging treatment using the same method as described above. The results are shown in Tables 13 and 14.

[0226] Table 13 UV radiation aging appearance stability performance results of liquid detergent compositions of Examples 1-16 and Comparative Examples 1-20

[0227]

[0228]

[0229] The appearance of the liquid detergent composition of Example 1 after UV irradiation aging is as follows: Figure 1 As shown; the appearance of the liquid detergent composition of Comparative Example 1 after UV irradiation aging is as follows Figure 2 As shown; the appearance of the liquid detergent composition of Comparative Example 2 after UV irradiation aging is as follows Figure 3 As shown; the appearance of the liquid detergent composition of Comparative Example 7 after UV irradiation aging is as follows Figure 4 shown.

[0230] As can be seen from Table 13, for the test samples of the test flavors containing a large amount of aldehydes and phenols, after 24 hours of ultraviolet radiation aging treatment, the appearance stability performance evaluation grades of Examples 1 to 16 are all good. The appearance stability performance evaluation grades of Comparative Examples 5, 8, 10, 11, and 18 to 20 are all good. As mentioned above, the ultraviolet radiation absorption rate of the above technical implementation scheme is greater than 20%. It shows that the use of the flavor light stabilizer drometrizole trisiloxane, diethylamino hydroxybenzoyl hexyl benzoate, and butyl methoxydibenzoylmethane that meet the technical requirements of the present invention can give the detergent composition good appearance stability. The flavor light stabilizers methylene bis-benzotriazolyl tetramethylbutylphenol, bis-ethylhexyloxyphenol methoxyphenyl triazine, 2,2'-dihydroxy-4-methoxybenzophenone and dibenzoylmethane that do not meet the technical invention scheme of the present invention have an ultraviolet radiation absorption rate greater than 20%, so they can also give the detergent composition good appearance stability.

[0231] However, the appearance of Comparative Example 1, which does not contain a fragrance light stabilizer, turns yellow obviously after ultraviolet radiation aging, and the appearance stability evaluation grade is poor. The fragrance light stabilizer content in Comparative Examples 2, 3, and 4 is 0.003%, which is lower than the lower limit of the dosage required by the technical solution of the present invention. The appearance of the detergent composition after radiation aging turns slightly yellow, and the appearance stability performance evaluation grade is general. The fragrance light stabilizers used in Comparative Examples 6, 7, 9, and 12 to 17 do not meet the technical requirements of the present invention. The appearance of the compositions after ultraviolet radiation aging turns yellow, and the evaluation grades are poor or general. Combined with the data in Table 8, it can be seen that the ultraviolet radiation absorption rates of the above comparative examples are all lower than 20%. It shows that the components in the fragrance that are easily discolored by light are relatively sensitive to ultraviolet light in the 320-400nm band. When the fragrance light stabilizer cannot fully absorb the radiation in this band, the detergent composition will have the undesirable phenomenon of appearance color change.

[0232] Table 14 UV radiation aging fragrance stability performance results of the liquid detergent compositions of Examples 1-16 and Comparative Examples 1-20

[0233]

[0234]

[0235] As shown in Table 14, after 24 hours of ultraviolet radiation aging treatment, the fragrance stability performance evaluation grades of the liquid detergent compositions of Examples 1 to 16 are all good. Combined with Table 13, the above technical implementation scheme can withstand ultraviolet radiation, maintain the fragrance type and fragrance intensity unchanged, and has a stable appearance without discoloration. It shows that the use of the fragrance light stabilizer that meets the technical requirements of the present invention can give the detergent composition good appearance stability and fragrance stability.

[0236] Comparative Examples 18 to 20 use the same fragrance light stabilizer as Examples 14 to 16, but the amount used exceeds the upper limit. In these examples and comparative examples, the amount of fragrance added is already 1% of the upper limit of the amount required by the present invention. The amount of fragrance light stabilizer added in Examples 14 to 16 is 0.01%, which has reached the requirement of improving the stability of fragrance in detergent compositions (see the above data and description). Therefore, from a cost perspective, the amount of fragrance light stabilizer does not need to be added excessively.

[0237] The liquid detergent compositions of Comparative Examples 5, 8, 10 and 11 were all evaluated as having good fragrance stability performance after being aged by ultraviolet radiation.

[0238] The liquid detergent compositions of Examples 1 to 16 and Comparative Examples 5, 8, 10 and 11 were subjected to high temperature accelerated aging treatment in the same manner as described above. The test results are shown in Tables 15 and 16.

[0239] Table 15 Appearance stability performance after high temperature accelerated aging of Examples 1-14 and Comparative Examples 5, 8, 10 and 11

[0240]

[0241]

[0242] The appearance of the liquid detergent composition of Comparative Example 8 after high temperature accelerated aging is as follows: Figure 5 As shown; the appearance of the liquid detergent composition of Comparative Example 10 after high temperature accelerated aging is as shown Figure 6 shown.

[0243] As shown in Table 15, for flavors 1 to 3, the appearance stability performance evaluation grades of Examples 1 to 16 using drometrizole trisiloxane, diethylamino hydroxybenzoyl hexyl benzoate, and butyl methoxydibenzoylmethane as the flavor light stabilizers were all good after 4 weeks of high-temperature accelerated aging treatment. This indicates that the use of the flavor light stabilizer that meets the technical requirements of the present invention can give the detergent composition good appearance stability and fragrance stability.

[0244] The liquid detergent compositions of Comparative Examples 5, 8 and 10 showed turbidity during high temperature accelerated aging, and the appearance stability performance evaluation grade was poor. The above comparative examples respectively used methylene bis-benzotriazolyl tetramethylbutylphenol, bis-ethylhexyloxyphenol methoxyphenyl triazine and 2,2'-dihydroxy-4-methoxybenzophenone as fragrance light stabilizers; none of them belong to the invention scheme of the present technology.

[0245] The appearance stability performance evaluation grade of Comparative Example 11 was good.

[0246] Table 16 Fragrance stability performance of Examples 1-16 and Comparative Example 11 at high temperature accelerated aging

[0247]

[0248] As can be seen from Table 16, for flavors 1 to 3, after 4 weeks of high-temperature accelerated aging treatment, the fragrance intensity and fragrance type of Examples 1 to 16, which use drometrizole trisiloxane, diethylamino hydroxybenzoyl hexyl benzoate, and butyl methoxydibenzoylmethane belonging to the technical invention scheme as fragrance light stabilizers, remain basically unchanged without generating new odors, and the fragrance stability performance evaluation grades are all good.

[0249] In Comparative Example 11, which uses dibenzoylmethane as a fragrance light stabilizer, both the fragrance type and fragrance intensity are changed, and the fragrance stability performance valence grade is average, and the technical effect of the technical solution of the present invention cannot be achieved.

[0250] Table 17 summarizes the ultraviolet absorption rate of the liquid detergent composition of Examples 1 to 16, as well as the appearance stability performance evaluation grade and the fragrance stability performance evaluation grade after accelerated aging (ultraviolet radiation aging, high temperature accelerated aging) treatment. All of them are good, and the ultraviolet absorption rate is above 20%. It can be seen that the use of the technical invention scheme has enhanced stability performance. After accelerated aging treatment, its fragrance type and fragrance intensity remain unchanged, no new odor is generated, and it has good component compatibility and appearance stability.

[0252]

[0253] The skin irritation test was performed on Examples 1 to 16 and Comparative Example 1, and the method was as described above. The test results are shown in Table 18. The data show that the skin irritation level of the liquid detergent composition of Examples 1 to 16 is "mild and non-irritating". Comparative Example 1 is used as a reference without adding a fragrance light stabilizer, and the skin irritation level is also "mild and non-irritating". It shows that the fragrance light stabilizer used in this technical solution will not increase the skin irritation of the detergent composition, and can give consumers a gentle and comfortable use experience.
