Abstract
Description
Technical Field
[0001] This invention relates to the field of fragrance additives, and in particular to an additive that increases the light stability of fragrances and its application. Background Technology
[0002] Fragrances are mixtures that impart a scent to products. The substances that produce the scent in fragrances are mainly volatile substances, which are generally unstable and easily decompose under light. When volatile substances decompose, the intensity of the aroma decreases significantly, and the aroma also changes. This means that most fragrances need to be stored away from light. However, when fragrances are added to products, some products cannot meet the requirements for long-term storage and sale in a dark environment, making it difficult for existing fragrances to meet usage needs.
[0003] To address these issues, existing fragrances contain a certain amount of stabilizers. However, these stabilizers can only slightly improve the light stability of the fragrance. When the fragrance is exposed to high temperatures and light for a long time, volatile substances are still prone to decomposition, affecting the aroma of the product. Therefore, there is still room for improvement. Summary of the Invention
[0004] To further improve the light stability of fragrances, this application provides an additive for increasing the light stability of fragrances and its application.
[0005] In a first aspect, this application provides an additive to increase the light stability of fragrances, employing the following technical solution: An additive for increasing the light stability of fragrances, comprising the following components in parts by weight: 1-5 parts light stabilizer; Antioxidant 1.5-3 parts; 3-7 parts of compound vegetable oil; Solvent: 85-94.5 parts; The compound vegetable oil is a blend of frankincense oil, carrot seed oil, croton seed oil, and arnica oil.
[0006] By adopting the above technical solution and adding light stabilizers and antioxidants, the light stability and antioxidant properties of the fragrance can be improved. In addition, the addition of a compound vegetable oil made from frankincense oil, carrot seed oil, croton oil, and arnica oil can significantly improve the high temperature resistance and light stability of volatile substances in the fragrance. It is not easy to decompose under high temperature and light, so the quality of the fragrance is more stable and can adapt to harsh storage environments, better meet the needs of downstream products, and has high economic value.
[0007] Preferably, the mass ratio of frankincense oil, carrot seed oil, croton oil, and arnica oil in the compound vegetable oil is 1-2:1-2:0.5-1.5:0.5-1.5.
[0008] By adopting the above technical solution and by specifically selecting the mass ratio of sesame oil, carrot seed oil, croton oil, and arnica oil, the effect of improving the light and heat stability of the fragrance is more significant, and the quality of the fragrance is better.
[0009] Preferably, the frankincense oil, carrot seed oil, croton oil, and arnica oil are all cold-pressed oils.
[0010] By adopting the above technical solution, and by specifically selecting frankincense oil, carrot seed oil, croton seed oil, and arnica oil as cold-pressed oils, the active ingredients are better preserved, thereby improving the light and heat stability of the fragrance.
[0011] Preferably, the light stabilizer is 2-(2'-hydroxy-5'-tert-octylphenyl)benzotriazole.
[0012] By adopting the above technical solution and specifically selecting 2-(2'-hydroxy-5'-tert-octylphenyl)benzotriazole, the effect of improving the light stability of fragrances is better, and the quality of fragrances is improved.
[0013] Preferably, the antioxidant is pentaerythritol tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate].
[0014] By adopting the above technical solution and specifically selecting pentaerythritol tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate], the antioxidant properties of the fragrance are enhanced, further improving the stability and quality of the fragrance.
[0015] Preferably, the solvent is isopropyl myristate.
[0016] By adopting the above technical solution and specifically selecting isopropyl myristate, the components have high solubility in the solvent, which can better exert a synergistic effect and improve the stability of the fragrance.
[0017] Secondly, this application provides an application of an additive that increases the light stability of fragrances, employing the following technical solution: An application of the above-mentioned additive for increasing the light stability of fragrances, wherein the additive for increasing the light stability of fragrances is added to the fragrance formulation to improve the stability of the fragrance.
[0018] By adopting the above technical solution, the stability of the fragrance can be significantly improved by adding additives that increase the light stability of the fragrance. The fragrance is less likely to experience a significant decrease in aroma intensity or change in aroma under high temperature and light conditions, and the resulting fragrance has higher economic value.
[0019] Preferably, the additive that increases the light stability of the fragrance has a mass content of 0.1-0.5% in the fragrance.
[0020] By adopting the above technical solution, the stability of the fragrance can be significantly improved by adding 0.1-0.5% of additives, without affecting the original aroma of the fragrance, effectively controlling the cost of the fragrance, and thus having high economic value.
[0021] In summary, this application has the following beneficial effects: 1. Because this application improves the light stability and antioxidant properties of fragrances by adding light stabilizers and antioxidants, and by adding a compound vegetable oil composed of frankincense oil, carrot seed oil, croton oil and arnica oil, it can significantly improve the high temperature resistance and light stability of volatile substances in fragrances. It is not easy to decompose under high temperature and light, so the quality of fragrances is more stable and can adapt to harsh storage environments, better meet the needs of downstream products, and has high economic value.
[0022] 2. In this application, the preferred method is to select the specific mass ratio of sesame oil, carrot seed oil, croton oil, and arnica oil, which makes the effect of improving the light stability and heat stability of the fragrance more significant and the fragrance quality better.
[0023] 3. In this application, frankincense oil, carrot seed oil, croton oil, and arnica oil are preferably selected as cold-pressed oils, which allows for better preservation of each active ingredient, thereby improving the light and heat stability of the fragrance. Detailed Implementation

[0068] Experiment 1 Additives that enhance the light stability of fragrances in each embodiment and comparative example were added to the fragrance formulation to prepare test samples, as detailed below: Mix 99.9g of vanilla flavoring and 0.1g of additives to increase the light stability of the flavoring evenly, pour into a transparent glass bottle, seal, and obtain the test sample.
[0069] The preparation method of vanilla flavoring is as follows: Mix 3.5g ethyl vanillin, 2g vanillin, 0.5g benzyl acetate, 0.25g ethyl acetoacetate, 1g ethyl lactate, 2g propyldecyl lactone, 0.25g butyldecyl lactone, 1g butyl dodecyl lactone, 0.5g propylnonyl lactone, 2g propyloctyl lactone, 1.2g ethyl maltol, and 85.8g dipropylene glycol evenly to obtain vanilla flavoring.
[0070] The prepared test sample was placed in a constant temperature environment of 45℃ and irradiated with a UVB lamp for 30 days to obtain the treated test sample.
[0071] The UVB lamp has a power of 40W and a wavelength of 365nm.
[0072] Volunteers were recruited to score the aroma intensity and aroma realism of the test sample and the processed test sample.
[0073] When scoring, the test sample and the treated test sample should be left open and ventilated for 30 minutes before scoring.
[0074] There were 100 volunteers, each of whom scored all the samples to be tested and the processed samples to be tested, and the average score was taken.
[0075] Aroma intensity: 1-10 points, 1 point is almost no aroma, 10 points is a strong aroma.
[0076] Scent realism: 1-10 points, 1 point is completely unlike vanilla essence, 10 points is very similar to vanilla essence.
[0077] The experimental data are detailed in Table 1.
[0078] Table 1
[0079] According to the data in Table 1, the test samples of each embodiment and comparative example all scored highly in terms of aroma intensity and aroma fidelity. However, after high temperature and ultraviolet irradiation treatment, each embodiment still maintained a strong aroma intensity and a relatively realistic aroma. In contrast, after high temperature and ultraviolet irradiation treatment, the aroma intensity and aroma fidelity scores of each comparative example decreased significantly. It can be seen that each embodiment has a better effect on improving the stability of the fragrance, proving that the compounding of frankincense oil, carrot seed oil, croton oil, and arnica oil can significantly improve the high temperature resistance and light resistance of the fragrance, so that the fragrance can better meet the needs of use.
[0080] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
