Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of skin care, in particular to a cactus essence oil with anti-wrinkle effect and a preparation method thereof. BACKGROUND

[0002] With the upgrading of skin care needs, anti-wrinkle skin care products have become one of the core categories in the cosmetic market. Essential oil anti-wrinkle products are favored by consumers due to their natural raw materials, good skin feel, and strong penetration ability. Cactus (OPUNTIA FICUS-INDICA) seed oil, as a new type of natural plant oil, is rich in linoleic acid, gamma-tocopherol, beta-sitosterol and various minerals, has excellent skin barrier repair, antioxidant and collagen regeneration promotion ability, and becomes a potential raw material in the anti-wrinkle skin care field, and is gradually applied to essential oil products.

[0003] However, the existing anti-wrinkle essential oil products containing cactus seed oil and related technologies still have many technical defects, and it is difficult to balance anti-wrinkle effect, skin tolerance, system stability and skin feel experience. The specific problems are as follows: Most of the existing products simply add cactus seed oil as a base oil without considering its physical and chemical properties, or only use a single anti-wrinkle ingredient, which mainly moisturizes the epidermis or promotes collagen synthesis in the dermis, and cannot achieve multi-target anti-wrinkle across skin layers. Some formulas blindly increase the concentration of active ingredients or essential oils in pursuit of efficacy, ignoring the formulation of soothing ingredients, resulting in strong irritation, which cannot be used on sensitive skin, and there is a technical contradiction between "strong efficacy and irritation, and mildness and low efficacy".

[0004] In addition, the existing anti-wrinkle essential oil also has problems such as oily skin feel, slow absorption speed, and uncoordinated aroma, which cannot meet the needs of consumers for comprehensive product quality. Therefore, it is necessary to develop a cactus essential oil that uses cactus seed oil as the core, scientifically formulates active ingredients such as bakuchiol and sea fennel oil, and combines with a special preparation process to achieve anti-wrinkle, high tolerance, high stability, and light skin feel, which is a technical problem to be solved in the current skin care field. SUMMARY

[0005] The purpose of the present application is to provide a cactus essential oil with anti-wrinkle effect and a preparation method thereof.

[0008] The present application also provides a preparation method of the cactus essence oil with anti-wrinkle effect, comprising the following steps: Step one, 1-3 parts of caprylic / capric triglyceride is preheated and mixed with bakuchiol to be completely dissolved and dispersed, and then the tocopherol is added and stirred uniformly to obtain an anti-aging active premix; Step two, the cactus seed oil, jojoba seed oil, squalane and the remaining caprylic / capric triglyceride are stirred and mixed to be in a uniform, clear and transparent state to obtain a base oil phase main body; Step three, the damascone, sandalwood oil, frankincense oil, carrot seed oil and geranium oil are stirred and mixed uniformly to obtain a natural essential oil mixture; Step four, the anti-aging active premix is added into the base oil phase main body and stirred, and then the sea fennel oil, the natural essential oil mixture and the farnesol are added and continuously stirred until the mixture is in a uniform, transparent, non-layered and non-visible particle state to obtain a primary mixture; Step five, the primary mixture is subjected to homogenization treatment in a vacuum homogenizer until the system is in a uniform and transparent state to obtain a homogenized liquid; Step six, the homogenized liquid is placed in a sterile container in a light-proof and sealed manner, and is in a clear and transparent state after standing to obtain the cactus essence oil.

[0009] Preferably, in step one, the preheating temperature is 30-35℃, the stirring speed is 200-400r / min, the stirring is performed for 5-10min first, and then the tocopherol is added and stirred for another 3-5min.

[0010] Preferably, in step two, the stirring speed is 100-200r / min, and the mixing time is 10-15min.

[0011] Preferably, in step three, the mixing temperature is 20-25 DEG C, the stirring speed is 100-200 r / min, and the stirring time is 2-3 min.

[0014] Preferably, in step six, the standing temperature is below 25 DEG C, and the standing time is 12-24 h.

[0015] Therefore, the cactus essence oil with anti-wrinkle effect and the preparation method thereof have the following beneficial effects: (1) By accurate formula matching, a multi-target anti-wrinkle system of "dermal collagen neogenesis, epidermal repair and microcirculation enhancement" is constructed: the psoralen stimulates the generation of I / III type collagen in the dermal layer and inhibits the degradation of collagen, the sea fennel oil activates skin stem cells and promotes the repair and update of the epidermal layer, and the two form a complementary anti-wrinkle network at different levels of the skin, combined with the microcirculation promotion and antioxidant synergistic effect of natural essential oils, realizing all-round anti-wrinkle across the skin layers; (2) By the synergistic collocation of farnesol and soothing essential oils such as sandalwood and frankincense, the slight irritation possibly caused by psoralen and high-concentration natural essential oils is effectively relieved, and the formula is free of preservatives, artificial fragrances and pigments throughout the process, combined with the low-temperature preparation process to avoid the oxidation of oils to produce irritants; (3) According to the original recipe, a special preparation process is designed, which includes active substance premixing and dissolution, low-temperature step-by-step mixing, vacuum homogenization and light-avoiding standing, to ensure that the components are fully mixed and uniformly dispersed, effectively avoiding problems such as active substance aggregation, essential oil stratification and turbid system; (4) By scientific collocation of base oil phase, taking cactus seed oil as the core, combined with the skin-friendly properties of jojoba seed oil, squalane and caprylic / capric triglyceride, good fluidity and permeability of the product are realized, and after application, the product is quickly absorbed without stickiness, floating oil, residue, and can form a light and thin water-locking and moisturizing film on the skin surface, with long-acting water-locking and refreshing skin feeling; meanwhile, through essential oil premixing and light-avoiding standing steps, the fragrance of natural essential oils is fully integrated, with good coordination and no pungent feeling; the vacuum homogenization and standing steps effectively remove the micro-bubbles in the system, the product has a delicate texture without granular feeling, and the overall sensory quality is excellent, greatly improving the consumer experience, solving the problems of oily skin feeling and uncoordinated fragrance of traditional essential oil products; (5) The cactus seed oil is rich in high unsaturated fatty acids, gamma-tocopherol and beta-sitosterol, combined with jojoba seed oil and squalane to simulate the structure of human sebum, which can deeply repair the skin barrier, improve the skin's own water retention capacity and resistance to external stimuli, and after human testing, the skin's transepidermal water loss (TEWL) value decreases by 17% or more, and the skin barrier repair effect is significant. Through the dual effects of barrier repair and active anti-wrinkle, the root cause of fine lines and wrinkles is improved, and the deepening of wrinkles is delayed, achieving long-term anti-aging of the skin, which is different from the design idea of the prior art which only pursues anti-wrinkle and ignores skin barrier repair; (6) The preparation process is controlled at a low temperature below 35 DEG C throughout, without high temperature treatment, only using general cosmetic production equipment such as stirring tanks and vacuum homogenizers, the steps are simple, the parameters are accurate, and the operation is convenient, avoiding high production cost and high operation difficulty caused by complex process; At the same time, there is no special material processing requirement in the process, and the time, speed, temperature and other parameters of each step are optimized, taking into account the retention of efficacy and production efficiency, which is suitable for large-scale industrial production and can also meet the needs of small-scale preparation, and has strong practicality and easy application.

[0029] Unless otherwise defined, the technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the use of related terms herein is merely for the purpose of describing particular embodiments and is not intended to limit this application.

[0030] In this invention, unless otherwise specified, all other test materials and instruments are conventional test materials in the field and can be purchased through commercial channels.

[0031] Example 1 This invention provides a cactus essential oil with anti-wrinkle effects, comprising the following ingredients by weight: 40 parts cactus seed oil, 18 parts jojoba seed oil, 12 parts squalane, 10 parts caprylic / capric triglycerides, 4 parts psoralen, 2 parts Rosa damascena flower oil, 1.5 parts sandalwood oil, 1.5 parts frankincense oil, 0.8 parts carrot seed oil, 0.8 parts geranium oil, 0.6 parts bisabolol, 5 parts sea fennel oil, and 0.3 parts tocopherol.

[0032] like Figure 1 As shown, its preparation method is as follows: Step one, take 2 parts of caprylic / capric triglyceride, preheat to 35℃, mix with psoralen, stir at 300r / min for 8min until completely dissolved and dispersed, add tocopherol and continue stirring for 4min, get anti-aging active premix.

[0033] Step two, mix cactus seed oil, jojoba seed oil, squalane and the remaining 8 parts of caprylic / capric triglyceride, stir at 35℃, 120r / min for 12min to be uniform and clear, get the main body of base oil phase.

[0034] Step three, mix rose oil, sandalwood oil, frankincense oil, carrot seed oil, geranium oil at 25℃, 150r / min for 2.5min, mix evenly to get natural essential oil mixture.

[0035] Step four, slowly add the anti-aging active premix into the main body of base oil phase, keep 35℃, 90r / min stirring for 22min. Then add sea fennel oil, natural essential oil mixture, bisabolol in turn, keep the same conditions continue stirring for 18min until uniform, transparent, no stratification and visible particles, get the initial solution.

[0036] Step five, transfer the initial solution into a vacuum homogenizer, homogenize at vacuum degree-0.09MPa, speed 1200r / min for 8min, until the system is uniform and transparent, get the homogenized liquid.

[0037] Step six, place the homogenized liquid in a light-proof sealed container, stand for 18 hours at 25℃ below to be clear and transparent, get the cactus essence oil.

[0038] Example 2 The only difference between this example and example 1 is that the raw material ratio uses another set of values within the scope of the claims: cactus seed oil 35 parts, jojoba seed oil 20 parts, squalane 15 parts, caprylic / capric triglyceride 8 parts, psoralen 5 parts, rose oil 1 part, sandalwood oil 2 parts, frankincense oil 1 part, carrot seed oil 1 part, geranium oil 0.5 parts, bisabolol 0.2 parts, sea fennel oil 8 parts, tocopherol 0.5 parts, the rest of the preparation conditions are exactly the same as example 1.

[0039] Example 3 The only difference between this example and example 1 is that the raw material ratio uses another set of values within the scope of the claims: cactus seed oil 45 parts, jojoba seed oil 15 parts, squalane 10 parts, caprylic / capric triglyceride 12 parts, psoralen 3 parts, rose oil 3 parts, sandalwood oil 1 part, frankincense oil 2 parts, carrot seed oil 0.5 parts, geranium oil 1 part, bisabolol 1.0 parts, sea fennel oil 3 parts, tocopherol 0.2 parts, the rest of the preparation conditions are exactly the same as example 1.

[0040] Comparative Example 1 The only difference between this comparative example and Example 1 is that bisabolol is not added to the formulation (i.e., bisabolol is 0 parts), and no other ingredients are used to fill the mass fraction. The remaining raw material ratios and preparation steps are exactly the same as in Example 1.

[0041] Comparative Example 2 The only difference between this comparative example and Example 1 is that psoralen and sea fennel oil are not added to the formula (i.e., both are 0 parts), and no other ingredients are used to fill in their mass fractions. The remaining raw material ratios and preparation steps are exactly the same as in Example 1.

[0042] Comparative Example 3 The only difference between this comparative example and Example 1 is that the preparation process is modified: during the mixing process in step four, the temperature is raised to 60°C for stirring, and the vacuum homogenization step in step five is canceled and replaced with ordinary stirring under normal pressure. The remaining raw material ratios and other steps are exactly the same as in Example 1.

[0043] Comparative Example 4 The only difference between this comparative example and Example 1 is the modification of the mixing order and method in step four. Specifically, instead of preparing the anti-aging active premix first, psoralen, tocopherol, sea fennel oil, bisabolol, and all essential oils (i.e., Rosa damascena flower oil, sandalwood oil, etc.) are all added to the pre-mixed base oil phase at once. The mixture is stirred for 40 minutes at the same temperature (35°C) and speed (90 r / min). The remaining raw material ratios and preparation steps are exactly the same as in Example 1.

[0044] Comparative Example 5 The only difference between this comparative example and Example 1 is that the light-protected standing process in step six is ​​completely omitted. That is, after completing the vacuum homogenization in step five, nitrogen filling is carried out immediately, and the remaining raw material ratios and preparation steps are exactly the same as in Example 1.

[0045] Performance was investigated for Examples 1-3 and Comparative Examples 1-5: In vitro efficacy testing: Strictly following the relevant requirements of the "Cosmetic Safety Technical Specifications (2015 Edition)" regarding physicochemical testing methods, microbiological testing methods, skin irritation tests (rabbit skin irritation test), and skin sensitization tests (guinea pig maximum value test), the following test items were tested: Physicochemical indicators: pH value (oil dilution method), heavy metal (lead, mercury, arsenic, cadmium) content, pathogenic bacteria (Staphylococcus aureus, Pseudomonas aeruginosa, fecal coliforms); Microbial limits: total bacterial count, total mold and yeast count; Skin safety: Single skin irritation test (rabbit), skin sensitization test (guinea pig); Physicochemical index: the pH value of the oil agent is 4.0-8.5; lead ≤10 mg / kg, mercury ≤1 mg / kg, arsenic ≤2 mg / kg, cadmium ≤5 mg / kg; no pathogenic bacteria are detected; Microbial limit: total bacterial count ≤500 CFU / g, total mold and yeast count ≤100 CFU / g; Skin irritation: the rabbit skin irritation test result is non-irritating (irritation index ≤0.5); Skin sensitization: the guinea pig skin sensitization test result is non-sensitizing (sensitization rate is 0).

[0046] The test results are shown in Table 1.

[0047] Table 1 Test results

[0048] As can be seen from Table 1, the physicochemical index, microbial index and skin safety index of Examples 1-3, Comparative Example 2 and Comparative Example 5 meet the requirements of the “Cosmetic Safety Technical Specification”, are non-irritating, non-sensitizing and have no safety risks.

[0049] Comparative Examples 1, 3 and 4, however, cause mild skin irritation or abnormal physicochemical state due to the absence of core soothing ingredients in the formula, incorrect process parameters and improper mixing method, which do not meet the requirements of the “Cosmetic Safety Technical Specification” and also prove that the soothing effect of bisabolol in the formula, low temperature control in the process, pre-mixed dissolution of active substances and vacuum homogenization are the keys to ensuring the safety of the sample, and any omission or modification will lead to safety risks.

[0050] Human skin efficacy evaluation was carried out on Examples 1-3, Comparative Example 2 and Comparative Example 5, and the experimental steps were as follows: 60 healthy volunteers aged 25-55 years old were selected, all of whom had facial fine lines / wrinkles (mainly at the corners of the eyes / laugh lines), no skin diseases, and no use of anti-wrinkle skin care products in the past 3 months. They were randomly divided into 5 groups, 12 people in each group, and each group used 1 sample.

[0051] After cleansing in the morning and evening every day, 2-3 drops of the sample were applied to the face, and the corners of the eyes and laugh line areas were massaged, and the rest of the skin care steps were unified (only use non-effective basic cleansing).

[0052] The test time points were before use, 14 days of use and 28 days of use.

[0053] According to the cosmetic efficacy evaluation standard, objective index testing was carried out using a skin texture analyzer (testing fine line depth / area), a skin elasticity instrument (testing tightness) and a skin water loss instrument (TEWL value, testing barrier repair ability), and subjective skin feel evaluation was combined with the volunteers.

[0054] Each group of samples was tested in triplicate, and the results were averaged. Comparative Example 2 (lacking core anti-wrinkle active) was used as a blank efficacy control, Comparative Example 5 (lacking the standing step) was used as a process control, and Examples 1-3 were used as experimental observation groups.

[0055] The efficacy evaluation indicators and standards are as follows: Fine line lightening rate: Fine line lightening rate = (0-day fine line depth - test-day fine line depth) / 0-day fine line depth x 100%, ≥ 25% is excellent, 15%-24% is good, 5%-14% is general, and < 5% is invalid; Skin tightening degree improvement rate: Tightening degree improvement rate = (test-day elasticity value - 0-day elasticity value) / 0-day elasticity value x 100%, ≥ 20% is excellent, 10%-19% is good, 3%-9% is general, and < 3% is invalid; Skin barrier repair ability: The TEWL value (trans-epidermal water loss) change rate was used as an indicator, TEWL value change rate = (0-day TEWL value - test-day TEWL value) / 0-day TEWL value x 100%, ≥ 15% is excellent, 8%-14% is good, 3%-7% is general, and < 3% is invalid.

[0056] The volunteers scored the absorption speed, skin stickiness, and aroma harmony (on a 10-point scale), ≥ 8 points is excellent, 6-7 points is good, and < 6 points is poor. The average score of each group was taken, and the test results are shown in Table 2 and Figure 2 .

[0057] Table 2 Test results

[0058] As can be seen from Table 2 and Figure 2 , Comparative Example 2 only lacks the psoralen and sea fennel oil core anti-wrinkle active, and the rest of the formulation and process are consistent with Example 1. However, the results show that the fine line lightening rate and tightening degree improvement rate of Comparative Example 2 are significantly lower than those of Example 1, while Examples 1-3 all have significant effects, indicating that psoralen and sea fennel oil are the core necessary components of the anti-wrinkle tightening of the present application, and the synergy of dermal collagen neogenesis and epidermal renewal repair is the key to achieving the anti-wrinkle effect.

[0059] Moreover, the TEWL value change rate of Comparative Example 2 is close to that of Examples 1-3, indicating that the barrier repair effect of the present application is achieved by the base oils such as cactus seed oil, jojoba seed oil, and squalane, and the core anti-wrinkle active does not affect the barrier repair.

[0060] The fine line lightening rate and the firmness improvement rate of Comparative Example 5 are both lower than those of Example 1 due to the absence of the light-shielding standing process. The reason is that the light-shielding standing process can make the active substance and the base oil phase further stably combined, improve the transdermal absorption efficiency of the active substance, and cancel the insufficient absorption of the active substance, thereby reducing the anti-wrinkle effect.

[0061] The TEWL value change rate of Comparative Example 5 is still excellent, indicating that the standing step has no obvious effect on the barrier repair effect, but affects the effect of the anti-wrinkle active substance.

[0062] The subjective skin feel score of Comparative Example 5 is reduced to good, because after the standing step is cancelled, there are small bubbles in the product residue, a slight floating oil feeling after application, a slow absorption speed, and a decrease in the coordination of the essential oil aroma.

[0063] It can be known from Comparative Examples 1-3 that the anti-wrinkle and barrier repair effects of the three are excellent and have no significant difference, indicating that the formula ratio range of the present application is precisely optimized, and any reasonable ratio within the scope of the claims can achieve excellent effects, rather than a single ratio by chance.

[0064] The TEWL value change rate of Example 3 is the best, because the ratio of bisabolol therein is the highest, which further strengthens the skin barrier repair and soothing effect, proving that the formula can be fine-tuned according to the skin quality requirements and has strong adaptability.

[0065] In summary, it can be known from Comparative Examples 1-3 and Comparative Examples 1-5 that the psoralen and sea fennel oil of the formula of the present application are the core necessary components for anti-wrinkle firmness, and the two form a dermal-epidermal complementary anti-wrinkle network, and the absence of them will completely have no anti-wrinkle effect; bisabolol is the core soothing component for skin safety, and the absence of it will cause skin irritation, which violates the “Cosmetic Safety Technical Specifications”; the base oil phase (cactus seed oil, etc.) realizes barrier repair and provides a basis for the active substance to function.

[0066] Therefore, the present application adopts the above-mentioned cactus essence oil with anti-wrinkle effect and its preparation method, takes cactus seed oil as the core base, scientifically matches psoralen, sea fennel oil and other core components with bisabolol and other soothing components, combines with the exclusive low-temperature premixing, step-by-step mixing, vacuum homogenization and light-shielding standing preparation process, effectively solves the technical defects of the existing anti-wrinkle essence oil, such as single effect, strong irritation, poor system stability, oily skin feeling and limited active substance effect, and the prepared cactus essence oil realizes the multiple improvements of anti-wrinkle, stability maintenance, skin feeling and production practicability, has outstanding substantial features and significant progress compared with the prior art, and has a wide market application prospect.

[0067] It should be pointed out finally that the above examples are only used to illustrate the technical solutions of the present application but not to limit it, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can still be modified or replaced equivalently, and these modifications or equivalent replacements should not make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present application.
