Description

Technical Field

[0001] The present invention relates to the technical field of skin care, in particular to A61Q, and more particularly to a barrier repairing, anti-wrinkle and firming oil phase composition, preparation and application thereof. Background Art

[0002] With people's pursuit of anti-aging, anti-wrinkle cosmetics continue to emerge in the market. However, the anti-wrinkle and anti-aging cosmetics on the market are uneven, the effects are slow, and the anti-wrinkle effects are not ideal.

[0003] Chinese patent CN202110712595 provides a skin-moistening and anti-wrinkle composition, including snake venom peptide, collagen, silk protein, hyaluronic acid, hexapeptide, vitamin A alcohol, pearl powder, emollients, moisturizers, plant extracts, emulsifiers, etc., to improve anti-wrinkle properties, but it needs to add emulsifiers to improve stability, which increases factors such as skin irritation, and the emulsifier is very easy to change its physical properties after high and low temperature conditions, affecting the stability of the product, and the skin glossiness, etc., cannot achieve satisfactory results. Chinese patent CN201710449778 provides an oil phase composition with anti-wrinkle effects, including apple seed oil, olive oil, almond oil and propyl gallate, etc., and its skin affinity needs to be improved. Summary of the invention

[0004] In view of some problems existing in the prior art, the first aspect of the present invention provides a barrier repair, anti-wrinkle and firming oil phase composition, including a plant oil fermentation product, a plant extract with antioxidant effect, and a softener.

[0005] Preferably, the plant oil fermentation product is selected from one or more of Candida / glucose / rapeseed methyl ester fermentation products, nut seed oil fermentation products, and camellia oil fermentation products.

[0006] Preferably, the nut seed oil fermentation product is an almond oil fermentation product and / or a sunflower seed oil fermentation product.

[0007] Preferably, the rapeseed oil is a fermentation product of Candida / glucose / rapeseed oleic acid methyl ester.

[0008] Preferably, the plant extract with antioxidant effect is selected from one or more of rice (ORYZASATIVA) germ oil, turmeric (CURCUMALONGA) root extract, tea (CAMELLIASINENSIS) leaf extract, gardenia (GARDENIAJASMINOIDES) fruit extract, schisandra (SCHIZANDRACHINENSIS) fruit extract, lithospermum (LITHOSPERMUMERYTHRORHIZON) root extract, EUPATORIUM FORTUNEI extract, DENDROBIUM NOBILE stem extract, olive (OLEA EUROPAEA) fruit oil, argania spinosa (ARGANIA SPINOSA) kernel oil, grape (VITIS VINIFERA) seed oil, sunflower (HELIANTHUS ANNUUS) seed oil, and low-erucic acid rapeseed oil.

[0009] The emollient described in the present application is not particularly limited, and those skilled in the art can make conventional selections, and examples thereof include caprylic / capric triglyceride, dimethicone, cetyl alcohol, palmityl alcohol, stearic acid, olive oil, and the like.

[0010] In one embodiment, the oil phase composition comprises, by weight, 1-10 parts of a complex 1 containing a plant oil fermentation product and 0.2-5 parts of a complex 2, wherein the complex 2 comprises a plant extract having an antioxidant effect and a softener.

[0011] In this application, the complex 1 is selected from Forest in Jeju Oil, Summer inJeju Oil, Sunset in Jeju Oil, Olive Oil, OilArgan, Oil Grape Seed, Oil Sunflower Seed, OilCanola, One or more of Oil Rice Germ.

[0012] In this application The INCI name of Oil Olive is Candida / Glucose / Methyl Rapeseed Ferment, OLEA EUROPAEA Fruit Oil; The INCI name of Oil Argan is Candida / Glucose / Methyl Rapeseed Ferment, Argania Spinosa Kernel Oil; The INCI name of Oil GrapeSeed is Candida / Glucose / Rapeseed Methyl Ester Ferment, VITIS VINIFERA Seed Oil; The INCI name of Oil Sunflower Seed is Candida / Glucose / Methyl Rapeseed Ferment, Helianthus Annuus Seed Oil; The INCI name for Oil Canola is Candida / Glucose / Rapeseed Methyl Ester Ferment, Canola Oil; The INCI name of Oil Rice Germ is Candida / Glucose / Rapeseed Methyl Oleate Ferment, Rice (ORYZA SATIVA) Germ Oil; The INCI name of Forest inJeju Oil is Candida / Glucose / Methyl Rapeseed Ferment, Rice (ORYZASATIVA) Germ Oil, Camellia (CAMELLIASINENSIS) Leaf Extract; The INCI name of Summer in Jeju Oil is Candida / Glucose / Methyl Rapeseed Ferment, Rice (ORYZASATIVA) Germ Oil, Turmeric (CURCUMALONGA) Root Extract; The INCI name of Sunset in Jeju Oil is Candida / Glucose / Rapeseed Methyl Ferment, Rice (ORYZASATIVA) Germ Oil, Gardenia (GARDENIA JASMINOIDES) Fruit Extract, Schisandra (SCHIZANDRA CHINENSIS) Fruit Extract, Curcumalonga Root Extract, Lithospermum (LITHOSPERMUMERYTHRORHIZON) Root Extract.

[0013] The essential oil of the present invention uses complex 1, which contains Candida albicans / glucose / rapeseed oleic acid methyl ester fermentation products, is fermented using biotechnology, and has a better hydrophilic-lipophilic balance.

[0014] In one embodiment, the complex 2 includes an emollient, an extract of EUPATORIUM FORTUNEI, an extract of LITHOSPERMUM ERYTHRORHIZON, and an extract of the stem of DENDROBIUM NOBILE.

[0015] The proportions of the raw materials in the composite 2 of the present application can be conventionally selected by those skilled in the art according to actual needs.

[0016] The present invention uses a complex 1 comprising a fermentation product of Candida albicans / glucose / rapeseed oleic acid methyl ester, rice (ORYZASATIVA) germ oil, and turmeric (CURCUMA LONGA) rhizome extract, and also comprises an emollient, an extract of Eupatorium fortunei, an extract of Lithospermum erythrorhizon, and an extract of Dendrobium nobile stem, so that the complex 1 has excellent anti-aging properties, effectively improves the moisture content of the stratum corneum of the skin, the elasticity of the skin, the firmness of the skin, the glossiness of the skin, and reduces the friction of the skin, etc. The inventor believes that the reason may be that the addition of the extract of Eupatorium fortunei, the extract of Lithospermum erythrorhizon, and the extract of Dendrobium nobile stem does not significantly affect the surface tension of the composition at this time, and at the same time, the addition of the extract of Eupatorium fortunei, the extract of Lithospermum erythrorhizon, and the extract of Dendrobium nobile stem does not significantly affect the surface tension of the composition, and at the same time, the surface tension of the composition is significantly reduced by the addition of the extract of Eupatorium fortunei, the extract of Lithospermum erythrorhizon, and the extract of Dendrobium nobile stem. The complex 1 of SATIVA germ oil and turmeric (CURCUMA LONGA) rhizome extract has good dispersion compatibility, and the components work together to break the interface existing in the gaps between keratin cells, enhance the penetration effect, and tightly combine with the moisture in the stratum corneum to prevent moisture loss.

[0017] In one embodiment, the weight ratio of Compound 1 to Compound 2 is 5:1.

[0018] The addition of complex 1 and complex 2 in the present invention effectively improves the condition of the skin. However, the inventors found that the addition of complex 2 easily resulted in precipitation at room temperature. The inventors found in experiments that when the weight ratio of complex 1 to complex 2 was 5:1, the problem of precipitation caused by complex 2 could be effectively solved. The inventors believed that this ratio may be the reason why complex 1 has better compatibility with complex 2 and other raw materials, avoiding the precipitation of too many freely moving molecules into the original system, and controlling the movement of the macromolecular chains within a certain space, thereby improving the stability of the entire system.

[0019] The second aspect of the present invention provides a skin care product containing the oil phase composition.

[0020] The skin care products of the present invention include but are not limited to lotions, gels, emulsions, creams, facial masks, essential oils, etc.

[0021] In one embodiment, the skin care product is an essence oil, which includes, by weight, 30-50 parts of a penetrant, 1-10 parts of a complex 1, 0.2-5 parts of a complex 2, 0.02-0.2 parts of a UV absorber, 0.05-0.2 parts of an antioxidant, and a lubricant supplemented to 100 parts.

[0022] Preferably, the essence oil comprises, by weight, 30-50 parts of penetrant, 1-10 parts of complex 1, 0.2-5 parts of complex 2, 0.02-0.2 parts of ultraviolet absorber, 0.05-0.2 parts of antioxidant, 2-20 parts of ester lubricant, and silicone lubricant supplemented to 100 parts.

[0023] Preferably, the ester lubricant is ethylhexyl palmitate and / or isononyl isononanoate, and more preferably, the ester lubricant is isononyl isononanoate. The present invention uses isononyl isononanoate as an ester lubricant, which has a dry and extremely soft hand feel and is an excellent lubricant. It also has extremely high solubility in silicone oil, is very stable in a formula containing silicone oil, and does not feel greasy after use.

[0024] The silicone oil lubricant of the present invention is not particularly limited, and those skilled in the art can make a conventional selection. Preferably, the lubricant is cyclopentasiloxane. The present invention uses cyclopentasiloxane to make the essence oil feel lubricated and silky.

[0025] The penetrant of the present invention is not particularly limited, and those skilled in the art can make conventional selections, and examples thereof include laurocapram, dimethyl isosorbide, N-n-alkyl benzisothiazolinone, cyclohexane, tetrahydropiperidin, squalane, etc. Preferably, the penetrant is squalane. In the essence oil of the present invention, squalane is used as a penetrant, which has excellent penetration and efficient oxygen carrying capacity, can adjust the water-oil balance of the skin, avoid rough and dull skin, and restore the original soft touch of the skin.

[0026] The present inventors have found that the use of a complex 1 comprising a fermentation product of Candida albicans / glucose / rapeseed oleic acid methyl ester, rice (ORYZA SATIVA) germ oil, and a turmeric (CURCUMA LONGA) rhizome extract, and a softener, an extract of EUPATORIUM FORTUNEI, an extract of lithospermum erythrorhizon, and an extract of DENDROBIUM NOBILE) stem extract, while improving the antioxidant and anti-aging effects, will produce a heavy greasy feeling when used by users, affecting the user experience. The addition of cyclopentasiloxane, squalane and isononyl isononanoate has been found to effectively improve the greasy feeling produced above, and has a good refreshing feeling, and further improves the penetration and anti-aging effects. The inventor believes that the possible reason is that the addition of cyclopentasiloxane, squalane and isononyl isononanoate makes the macromolecules with strong intermolecular lipophilic effects and strong bonding have higher free mobility, improves the skin's absorption of various raw materials, and reduces the greasy feeling.

[0027] The antioxidant in the present invention is not particularly limited, and those skilled in the art can make conventional selections, and examples thereof include tocopherol acetate, ascorbyl tetraisopalmitate, coenzyme Q10, β-carotene, lycopene, tea polyphenols, vitamin C, 2,6-di-tert-butyl-4-methylphenol, etc. Preferably, the antioxidant includes a first antioxidant and a second antioxidant, and preferably, the first antioxidant is tocopherol acetate.

[0028] The second antioxidant is ascorbic acid tetraisopalmitate, and the weight ratio of the first antioxidant to the second antioxidant is (0.05-0.2):0.02.

[0029] The ultraviolet absorber of the present invention is not particularly limited, and those skilled in the art can make conventional selections, and examples thereof include p-aminobenzoic acid series, cinnamic acid series, salicylic acid series, carboxybenzophenone series, coumarin, quinine salts, amino acid methyl esters, α-phenylbenzimidazole sulfonic acid, etc. Preferably, the ultraviolet absorber is benzotriazolyl dodecyl p-cresol.

[0030] The third aspect of the present invention provides a method for preparing the essential oil, comprising the following steps:

[0031] 1. Mix the ultraviolet absorber, the second antioxidant, and 2-10 wt % of the ester lubricant to obtain a pre-formulated solution 1;

[0032] 2. Stir the remaining ester lubricant and compound 2, then add the remaining raw materials and mix them uniformly to obtain a mixed solution 1;

[0033] 3. Add the pre-prepared liquid 1 into the mixed liquid 1 above and stir until uniform.

[0034] The 2-10 wt % ester lubricant in the present invention refers to 2-10 wt % of the total amount of the essential oil.

[0035] In the preparation method of the present invention, part of the ester lubricant is mixed with the compound 2 and then added into the system, thereby avoiding the problem of molecular precipitation caused by direct mixing of the compound 2 with the silicone oil lubricant.

[0036] In one embodiment, the method for preparing the essential oil comprises the following steps:

[0037] 1. Preparation of pre-mixed solution 1: Mix benzotriazolyl dodecyl p-cresol, ascorbic acid tetraisopalmitate and 2-10 wt % isononyl isononanoate, heat to 60-65° C., and stir until uniform;

[0038] 2. After the remaining isononyl isononanoate and caprylic / capric triglyceride, Eupatorium Fortunei extract, Lithospermum Erythrorhizon extract, and Dendrobium Nobile stem extract are stirred uniformly, cyclopentasiloxane, squalane, Candida albicans / glucose / rapeseed oleic acid methyl ester fermentation product, rice (ORYZA SATIVA) germ oil, turmeric (CURCUMA LONGA) rhizome extract, and tocopherol acetate are added to obtain a mixed solution 1, and the mixture is stirred until uniform;

[0039] 3. Add the pre-prepared liquid 1 to the mixed liquid 1, stir evenly, and filter through an 800-mesh filter.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] The present invention uses plant oil fermentation products, that is, plant oil fermented by biotechnology, so that the plant oil has the characteristics of hydrophilic-amyphilic balance, has high affinity with the skin, can improve the skin's absorption of oil, and is compounded with caprylic / capric triglyceride, Eupatorium fortunei extract, Lithospermum erythrorhizon extract and Dendrobium nobile stem extract, which can soften the skin while improving the elasticity of the skin and moisturizing the skin, so that the oil phase composition has the effects of moisturizing, anti-inflammatory, anti-oxidation, repairing and anti-aging.

[0042] In addition, the oil phase composition is applied to skin care products, which has the effect of increasing the moisture content of the skin's stratum corneum, skin elasticity, skin firmness and skin glossiness; reducing the skin's transepidermal water loss rate, skin oil content, skin friction and cheek wrinkle parameters; and improving the number of nasolabial folds, the area of ​​nasolabial folds and forehead wrinkles.
