Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and particularly relates to a micron camellia oil moisturizing and emollient spray and a preparation method thereof. Background Art

[0002] The particle size of the current moisturizing spray atomized particles is larger than the pores of the skin (most of the particle sizes are above 100 microns), which is not conducive to skin absorption.

[0003] For example, Chinese patent application CN 109223669 A discloses a spray-type moisturizing body lotion, which includes the following components in weight percentage: 2.6%-33% emollient, 0.2-10% emulsifier, 0.02%-5% preservative, 0.33%-29% flu modifier, 1.12%-16% moisturizer, 0.01%-0.5% triethanolamine, 0.01%-1% disodium ethylenediaminetetraacetic acid, 0.01%-2% dipotassium glycyrrhizinate, 0.01%-0.5% essence, 0.5%-5% aloe extract and 0.5%-5% tremella extract, and the balance is deionized water. The body lotion of the invention satisfies the spray effect required by the spray body lotion by adding flu modifier and optimizing the added content of flu modifier, so that the body lotion can spray the lotion evenly, thereby achieving a refreshing and moisturizing effect. However, the particles of this body lotion after atomization are large, which is not conducive to skin absorption.

[0004] Another example is Chinese patent CN 107822904 B, which discloses a spray emulsion composition and a preparation method thereof. The spray emulsion composition includes an oil phase A, an aqueous phase B, a phase C, and a phase D; the oil phase A includes: an oil-soluble emulsifier, an emollient, a grease component, and a silicone oil; the aqueous phase B includes: water, acrylic acid (ester) / behenyl alcohol polyether-25 methacrylate copolymer, a water-soluble emulsifier, a moisturizer, and allantoin; the phase C includes: aminomethyl propanol and triethanolamine; the phase D includes: phenoxyethanol and parahydroxyacetophenone. The spray emulsion composition controls the oil phase and the aqueous phase in a specific ratio so that the system viscosity is less than 15,000 cps, and the acrylic acid (ester) / behenyl alcohol polyether-25 methacrylate copolymer is combined with aminomethyl propanol to control the system pH value between 7.0 and 7.5. The final spray emulsion composition can obtain a delicate emulsion through a sprayer. However, the particles of the spray emulsion composition after atomization by a sprayer are still large, which is also not conducive to skin absorption.

[0005] Therefore, in view of the problem that the particle size of the atomized particles of the current moisturizing spray is larger than the pores of the skin, which is not conducive to skin absorption, the present invention provides a micron camellia oil moisturizing spray and a preparation method thereof. Summary of the invention

[0006] In order to solve the problems existing in the prior art, the purpose of the present invention is to provide a micron camellia oil moisturizing spray and a preparation method thereof. The particles of the micron camellia oil moisturizing spray sprayed by the present invention are kept below 100 microns (more than 90% of the particle size is below 80 microns), the particle size is smaller than the size of human pores, and with the help of a penetration enhancer, the camellia oil moisturizing spray can easily penetrate the skin layer, lock the skin moisture, and play a moisturizing and moisturizing effect.

[0007] The technical solution of the present invention is:

[0008] A micron camellia oil moisturizing spray comprises the following components in parts by weight: 80-105 parts of a solubilizer, 0.1-10 parts of oil, 0.3-0.6 parts of an emulsifier and 0.02-2 parts of an active substance.

[0009] Furthermore, the micron camellia oil moisturizing spray comprises the following components in parts by weight: 96.5-105 parts of solubilizer, 3-8 parts of oil, 0.5-0.6 parts of emulsifier and 1-2 parts of active substance.

[0010] Further, the solubilizer comprises the following components in parts by weight: 65 parts of isododecane, 25 parts of isohexadecane, 4 parts of isononyl isononanoate and 2.5 parts of hexamethyldisiloxane.

[0011] Furthermore, the relative density of the solubilizing agent is lower than 0.8 g / cm 3 .

[0012] Furthermore, the oil is camellia oil or olive oil.

[0013] Furthermore, the emulsifier is PEG-40 hydrogenated castor; the PEG-40 hydrogenated castor also plays a role in promoting penetration in the micron camellia oil moisturizing spray of the present invention.

[0014] Furthermore, the active substance includes the following components in parts by weight: 0.01-1 part of vitamin E and 0.01-1 part of jojoba oil, or includes the following components in parts by weight: 0.01-1 part of vitamin C and 0.01-1 part of jojoba oil.

[0015] Furthermore, the micron camellia oil moisturizing spray comprises the following components in parts by weight: 65 parts of isododecane, 25 parts of isohexadecane, 4 parts of isononyl isononanoate, 2.5 parts of hexamethyldisiloxane, 2 parts of camellia oil, 1 part of olive oil, 0.5 parts of PEG-40 hydrogenated castor oil, 0.5 parts of vitamin E and 0.5 parts of jojoba oil.

[0016] Moreover, the present invention also provides a method for preparing the above-mentioned micron camellia oil moisturizing spray, comprising the following preparation steps:

[0017] Step 1: Mix and stir the oil, emulsifier and active substance to obtain phase A;

[0018] Step 2: Mix the components in the solubilizer, then add phase A to the mixed solubilizer, mix and stir evenly to obtain phase B;

[0019] Step 3: Add the above phase B into the binary aerosol can, set the pressure to less than 1MPa, and the aperture of the atomization button to 0.25mm±0.02mm to obtain the micron camellia oil moisturizing spray.

[0020] Due to the inherent surface tension of the liquid in the system, the moisturizing products atomized by the sprayer will re-aggregate to form large droplets and large particles after gathering on the skin surface. Therefore, the particle size of the particles atomized by the current moisturizing spray is larger than the pores of the skin (most of the particle sizes are above 100 microns), which is not conducive to skin absorption. However, the present invention breaks the surface tension of camellia oil by using a solubilizer with a specific ratio and specific density, and then cooperates with oils and active substances to reduce the surface tension of the liquid in the system to below 28mN / m; then the liquid is sprayed out by pressure, and after the dual effects of the mist point and pressure, the liquid is sprayed out to maintain the particle size of the liquid particles concentrated between 10-100 microns, thereby accelerating the absorption of the active ingredients in the cosmetics.

[0021] Compared with the prior art, the micron camellia oil moisturizing spray and its preparation method provided by the present invention have the following advantages:

[0022] The present invention breaks the surface tension of camellia oil by using a solubilizer with a specific ratio and a specific density, and then cooperates with oil and active substances to reduce the surface tension of liquid in the system to below 28mN / m; then atomizes the camellia oil moisturizing spray by using a low pressure below 1Mpa and a fog point with an aperture of 0.25mm±0.02mm, so that the sprayed moisturizing spray particles are kept below 100 microns (more than 90% of the particle diameters are below 80 microns), the moisturizing spray particle diameter is smaller than the size of human pores, and with the help of a penetration enhancer, the camellia oil moisturizing spray is easy to penetrate the skin layer, lock the skin moisture, and play a moisturizing and moisturizing effect.
