The compounded oil composition of the present invention is composed of propylene glycol dibenzoate and triheptyl, specifically, the propylene glycol dibenzoate and triheptyl are compounded in a mass ratio of 1.75:1 to 1.9:1. The compounded oil composition of the present invention is compounded with sustainable cosmetic raw materials propylene glycol dibenzoate and triheptyl, and the performance of the compounded oil composition in skin feel and refractive index is very similar to that of ethylhexyl methoxycinnamate, which can provide a good alternative to existing formulas that add ethylhexyl methoxycinnamate as a skin feel improvement and high refractive index or formulas that pre-use ethylhexyl methoxycinnamate as a skin feel improvement and high refractive index. The compounded oil composition of the present invention can be applied to cosmetics including creams, emulsions or foundation liquids, especially to replace ethylhexyl methoxycinnamate as a skin feel improvement and high refractive index additive added to the formula.

Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and in particular to a compound oil and fat composition and application thereof. Background Art

[0002] Ethylhexyl methoxycinnamate (MCX) contains phenyl and unsaturated bonds. It is not only a good absorber in the UVB region, but also has the gloss and soft skin feel required for liquid foundation formulas, which is a feature that other conventional oils rarely have.

[0003] That is because ethylhexyl methoxycinnamate not only plays an important role in UVB protection, but also contributes to its unique skin feel, which makes cosmetic formulators prefer it when designing formulas.

[0004] At present, typical oils and fats that can provide high refractive index and contain benzene rings include: C12-15 alcohol benzoate, C12-14 alcohol benzoate, dipropylene glycol dibenzoate, tri(ethylhexyl alcohol) trimellitate, pentaerythritol tetra(behenic acid / benzoic acid / ethylhexyl) ester, pentaerythritol tetra(ethylhexyl / benzoic acid) ester, salicylates, phenyl silicone oil, etc. However, these oils and fats have a large difference in skin feel from ethylhexyl methoxycinnamate, and cannot effectively replace ethylhexyl methoxycinnamate. Rapeseed oil and sunflower seed oil have a richer skin feel and can be used to replace ethylhexyl methoxycinnamate, or their compound oils can be used to replace it. However, these oils or compound oils have the problem of poor skin feel and easy oxidation and rancidity during use; or the problem that both cannot be taken into account at the same time, and cannot effectively replace ethylhexyl methoxycinnamate.

[0005] In the prior art, medium-chain fatty acid triglycerides (MCT) are mainly saturated fatty acids composed of 8 to 12 carbon atoms and are widely used in the food field. However, there is no oil composition that combines triheptanoin (also known as triheptanoin) with propylene glycol dibenzoate, nor is there an application of combining triheptanoin with propylene glycol dibenzoate for use in cosmetics. The two are usually used separately. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the use of ethylhexyl methoxycinnamate in cosmetics in the prior art is limited, and the oil or compound oil used as a substitute cannot meet the requirements of refractive index and / or skin feel, and provide a compound oil composition that replaces ethylhexyl methoxycinnamate.

[0007] Another object of the present invention is to provide an application of the compound oil and fat composition.

[0008] The purpose of the present invention is achieved through the following technical solutions.

[0009] On the one hand, the compound oil composition provided by the present invention is composed of propylene glycol dibenzoate and triheptanol.

[0010] In a preferred embodiment, the compound oil composition of the present invention is composed of the propylene glycol dibenzoate and the triheptylbenzene in a mass ratio of 1.75:1 to 1.9:1.

[0011] In a specific preferred embodiment, the compound oil composition of the present invention is composed of the propylene glycol dibenzoate and the triheptylbenzene in a mass ratio of 1.75:1.

[0012] In a further preferred embodiment, the refractive index of the compound oil composition is 1.5076-1.5103.

[0013] In a further preferred embodiment, the refractive index of the compound oil composition is 1.5083.

[0014] In a further preferred embodiment, the specific gravity of the compound oil composition relative to water is 1.0797 to 1.0843.

[0015] In a further preferred embodiment, the specific gravity of the compound oil composition relative to water is 1.0809.

[0016] In another aspect, the present invention provides use of any of the above-mentioned compound oil and fat compositions in cosmetics.

[0017] In a preferred embodiment, the cosmetic comprises a cream, a lotion or a liquid foundation.

[0018] In a preferred embodiment, the amount of the composite oil composition added to the cream, lotion or foundation is 3.2% by mass.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] The compounded oil and fat composition of the present invention is compounded with propylene glycol dibenzoate and triheptyl, both of which are raw material components with high safety and sustainability, and the compounded oil and fat composition is very similar to ethylhexyl methoxycinnamate in terms of skin feel and refractive index, thereby providing a good substitute for existing formulas that add ethylhexyl methoxycinnamate as a skin feel improvement and high refractive index or formulas that pre-use ethylhexyl methoxycinnamate as a skin feel improvement and high refractive index.

[0021] The composite oil composition of the present invention can be applied to cosmetics, especially to replace ethylhexyl methoxycinnamate as a skin feel improvement and high refractive index additive added to formulas, including creams, emulsions or foundation liquids, so that the obtained products have good skin feel effects.

[0048] In addition, "and combinations thereof" in the specification refers to any combination of all listed items. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0049] Unless otherwise specified, all technical and scientific terms used herein have the standard meaning in the field to which the claimed subject matter belongs. If there are multiple definitions for a term, the definition herein shall prevail.

[0050] Unless otherwise indicated, this invention employs standard nomenclature and standard laboratory procedures and techniques of analytical chemistry, synthetic organic chemistry, and optics.

[0051] Without violating the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present invention.

[0052] The technical solution of the present invention is described in detail below in conjunction with specific embodiments.

[0053] In the following specific examples, some of the raw materials used and their sources are as follows:

[0054] Ethylhexyl methoxycinnamate, BASF, trade name MC 80.

[0055] Propylene glycol dibenzoate, Inolex, trade name LexFeel Shine.

[0056] Triheptanoin (triheptanoin), Inolex, trade name SustOleo MCT.

[0057] Sunflower (HELIANTHUS ANNUUS) seed oil, Heyiyuan Biotechnology Co., Ltd., first-grade sunflower seed oil.

[0058] Rapeseed oil, Heyiyuan Biotechnology Co., Ltd., first-grade rapeseed oil.

[0059] Dipentaerythritol hexa C5-9 acid esters, Inolex, trade name LexFeel 350.

[0060] Among them, the molecular structural formulas of ethylhexyl methoxycinnamate, propylene glycol dibenzoate, triheptyl, and dipentaerythritol hexa C5-9 acid esters are shown in the following formulas I, II, III, and IV, respectively.

[0061]

[0062]

[0063] The oil composition of propylene glycol dibenzoate and triheptyl can provide a refractive index and skin feel similar to ethylhexyl methoxycinnamate. Among them, in terms of structure, both propylene glycol dibenzoate and ethylhexyl methoxycinnamate contain phenyl groups, which can provide high gloss; triheptyl is a triglyceride containing C7, which can simulate the carbon chain of ethylhexyl ester on ethylhexyl methoxycinnamate. Therefore, under a specific ratio, the oil composition of propylene glycol dibenzoate and triheptyl can provide a refractive index, specific gravity and skin feel that are extremely similar to ethylhexyl methoxycinnamate.

[0064] Dipentaerythritol hexa C5-9 acid esters (LexFeel 350) are short-chain fatty acid esters with steric hindrance effect formed by the esterification of two pentaerythritol molecules and six C5-9 short-chain fatty acids. They are highly stable and moisturizing, with a relative density of 0.966 and a refractive index of 1.4560.

[0065] In addition, sunflower (HELIANTHUS ANNUUS) seed oil and rapeseed oil are natural plant oils whose main components are triglycerides, wherein the content of triglycerides is above 95%, and they can provide skin feel and refractive index close to those of ethylhexyl methoxycinnamate.

[0066] Examples 1-23

[0067] The compositions of different oils or compound oils of Examples 1-23 are provided below, and their corresponding refractive index (Refractive Index@25°C) and specific gravity (Specific Grav.@25°C / 25°C) are tested. The oils and their test results are shown in Table 1 below.

[0068] Table 1 Grease composition and refractive index and specific gravity test results of Examples 1-23

[0069]

[0070]

[0071] According to Table 1, the grease of Example 1 Comparison of MC 80 with the emollients of Examples 2-6 and comparison of the oil of Example 1 with the emollients of Examples 19-23 shows that although the refractive index of propylene glycol dibenzoate (LexFeel Shine) is close to that of ethylhexyl methoxycinnamate, its specific gravity is higher than that of ethylhexyl methoxycinnamate, and it is not possible to take into account both the similar refractive index and specific gravity, and it is difficult to provide a skin feel similar to that of ethylhexyl methoxycinnamate. The refractive index of triheptyl (SustOleoMCT), sunflower seed oil, rapeseed oil and dipentaerythritol hexa C5-9 acid esters (LexFeel 350) are all lower than 1.50, and the specific gravity is lower than 1.0, which are far lower than the refractive index and specific gravity of ethylhexyl methoxycinnamate. In addition, when SustOleo MCT is compounded with sunflower seed oil, rapeseed oil and dipentaerythritol hexa C5-9 acid esters, or propylene glycol dibenzoate (LexFeel Shine) is compounded with sunflower seed oil, the refractive index and specific gravity of the obtained compounded oil composition are still significantly different from those of ethylhexyl methoxycinnamate, and the refractive index and specific gravity cannot be simultaneously close to ethylhexyl methoxycinnamate, and it is difficult to provide a refractive index and skin feel similar to those of ethylhexyl methoxycinnamate; the refractive index and specific gravity of propylene glycol dibenzoate (LexFeel Shine) compounded with rapeseed oil are closer to ethylhexyl methoxycinnamate.

[0072] The oil compositions of Emollient Grease A to Emollient Grease L, which are compounded with propylene glycol dibenzoate (LexFeel Shine) and triheptanoin (SustOleo MCT) in a mass ratio of 1.4:1 to 2.3:1, have a refractive index of more than 1.50 and are close to the refractive index (1.545) of ethylhexyl methoxycinnamate, and a specific gravity of more than 1.0 and are close to the specific gravity (1.009) of ethylhexyl methoxycinnamate. In particular, the compounded oil composition with a mass ratio of propylene glycol dibenzoate to triheptanoin in a range of 1.75:1 to 1.9:1 is closer to ethylhexyl methoxycinnamate in terms of refractive index and specific gravity, thereby providing a refractive index, specific gravity and skin feel similar to those of ethylhexyl methoxycinnamate.

[0073] 1. Sensory evaluation of oils and fats

[0074] The grease of Example 1 MC 80 and the compound oil composition emollient AQ of Examples 7-23 were subjected to sensory evaluation. The sensory evaluation was conducted by 7 panel members who had received relevant training, including visual and tactile evaluation. The specific evaluation items included spreadability, silky feel, softness, moisturizing feel, absorbency, moisturizing property, glossiness, and film-forming property.

[0075] Evaluation test method: drop equal amounts of 2 oils weighing about 0.01g on two locations on the inside of the wrist at the same time, apply them in a counterclockwise circular motion with the fingertips, evaluate the skin feel of each oil, and give a score. MC 80 is the standard sample, and each index is 0 points. The score of the comparison sample emollient is between -2 and 2. The score is positive if it is better than the standard sample, and negative if it is worse than the standard sample. The higher the score, the better the emollient is in this item.

[0076] Emollient AQ and oil The sensory evaluation comparison results of MC 80 are as follows: Figure 1-Figure 17 As shown.

[0077] Among them, Figure 1-17The evaluation and comparison results show that the compound emollient E of Example 11 with a composition of LexFeel Shine:SustOleo MCT=1.75:1, the compound emollient F of Example 12 with a composition of LexFeel Shine:SustOleo MCT=1.8:1, the compound emollient G of Example 13 with LexFeel Shine:SustOleo MCT=1.85:1, the compound emollient H of Example 14 with a composition of LexFeelShine:SustOleo MCT=1.9:1, the compound emollient N of Example 20 with a composition of rapeseed oil:SustOleo MCT=4:1, and the compound emollient Q of Example 23 with a composition of rapeseed oil:LexFeel Shine=3:7 are comparable to ethylhexyl methoxycinnamate ( Especially the compound emollient E of Example 11 with the composition of LexFeel Shine:SustOleo MCT=1.75:1 and ethylhexyl methoxycinnamate MC80 is closest to the skin feel.

[0078] Furthermore, LexFeel Shine, SustOleo MCT, sunflower seed oil and rapeseed oil were subjected to accelerated aging tests at 45°C for one month with titanium dioxide (titanium dioxide & lauroyl lysine & aluminum hydroxide) of the trade name VHK-CR-LL at a mass ratio of 1:1. Both sunflower seed oil and rapeseed oil became rancid and produced odors, that is, a large amount of sunflower seed oil and rapeseed oil were prone to oxidative rancidity, while LexFeel Shine and SustOleo MCT did not become rancid. Therefore, although the refractive index and specific gravity of the compound of propylene glycol dibenzoate (LexFeel Shine) and rapeseed oil are closer to ethylhexyl methoxycinnamate, rapeseed oil is very easy to oxidize and become rancid in the presence of color powder, and the compound of propylene glycol dibenzoate (LexFeelShine) and rapeseed oil cannot be used as a fat substitute for ethylhexyl methoxycinnamate.

[0079] It can be seen that the compound emollient N of Example 20 with a composition of rapeseed oil: SustOleo MCT = 4:1 and the compound emollient Q of Example 23 with a composition of rapeseed oil: LexFeel Shine = 3:7 are not feasible in practical applications, while the emollient with a composition of LexFeel Shine: SustOleo MCT = 1.75:1 to 1.9:1 has good stability and can be used in practice.

[0080] Examples 24-30

[0081] The grease of Example 1 MC 80 and the compound emollient C, emollient E, emollient G, emollient H, emollient I and emollient P of Examples 9, 11, 13-15 and 22 were respectively added to the preparation of liquid foundation. The corresponding liquid foundation compositions of Examples 24-30 are shown in Table 2.

[0082] Table 2 Composition of the foundation liquid of Examples 24-30 (mass percentage, w / w%)

[0083]

[0084]

[0085]

[0086] The steps for preparing the foundation liquid of Examples 24-30 are as follows:

[0087] Mix the raw materials of component A, heat to 80℃, homogenize at 3000r / min for 1min, and stir evenly, add the raw materials of component B, stir evenly, and cool to 70℃ for use. Mix the raw materials of component C, disperse evenly with SpeedMixer high-speed disperser, add the raw materials of component D to the mixed raw materials of component C in sequence, then heat to 70℃ and stir evenly. Slowly add the mixed raw materials of components A and B to the mixed raw materials of components C and D, stir at a stirring speed of 500-700r / min for 6 minutes, and then homogenize at 2500-3000r / min for 2-3 minutes. Discharge the material when stirring and cooling to below 45℃.

[0088] 2. Sensory evaluation of liquid foundation

[0089] The liquid foundations of Examples 24-30 were subjected to a sensory evaluation using visual and tactile methods by 7 panel members who had received relevant training. The specific evaluation items included appearance texture, spreadability, smearing feeling, fit, moisturizing degree, smearable time, residual film, glossiness during smearing, final softness, final glossiness, and whether the powder was stuck or floated.

[0090] Evaluation method: Take 0.01 to 0.02g of each sample on the back of the hand or the inside of the wrist, and use the other hand to gently smear 8 to 15 times, and evaluate the appearance texture, spreadability, spreadability, docility, moisturizing, spreadable time, residual film, glossiness during application, final softness, final glossiness, whether the powder is stuck or floating. 0 to 10 points. The higher the score, the better the appearance texture, spreadability, spreadability, docility, moisturizing, final softness, and glossiness; the lower the score, the shorter the spreadable time, the thinner the residual film, and the absence of powder sticking or floating.

[0091] The foundation liquids 651-225E to 651-225J corresponding to Examples 25-30 and the added oil corresponding to Example 24 The sensory evaluation comparison results of MC 80 and 651-225D are as follows: Figure 18-Figure 23 shown.

[0092] Depend on Figure 18-23 The evaluation results show that the skin feel effects of the foundation liquids 651-225E, 651-225F, and 651-225G added with the compound emollient E of Example 11, the compound emollient G of Example 13, and the compound emollient H of Example 14 are similar to those of the foundation liquids 651-225E, 651-225F, and 651-225G added with the compound emollient H of Example 14. The skin feel of MC 80's liquid foundation 651-225D is closer, especially the skin feel of liquid foundation 651-225E is closest to the skin feel of liquid foundation 651-225D, that is, the liquid foundation prepared by adding equal amounts of ethylhexyl methoxycinnamate to the liquid foundation in a compounding ratio of LexFeel Shine and SustOleo MCT of 1.75:1 to replace ethylhexyl methoxycinnamate can obtain a skin feel that is basically consistent with the liquid foundation added with ethylhexyl methoxycinnamate.

[0093] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, this specification does not describe all possible combinations of the technical features in the above-mentioned embodiments. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Moreover, the above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent.

[0094] It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these modifications and improvements all belong to the protection scope of the present invention.
