Description

FIELD OF THE INVENTION [0001] The present invention relates to fragrant oil porous particle compositions,

The present invention relates to a fragrance-oil porous particle composition and a process for its preparation. More particularly, the present invention relates to a fragrance-oil porous particle composition stabilized by a water-soluble polymer and containing a fragrant oil, an emulsifier and hygroscopic porous particles, and controlling the volatilization rate of the fragrance oil according to the degree of contact with water.

Fragrance oil, also called aroma oil, is composed of synthetic aromatic oils or natural essential oils. Synthetic aroma oil is a synthetic compound that is odorous and odorous, and is highly volatile, and the smell is transmitted to the body through the upper part of the nose. Fragrant oil is used industrially, for example, by adding fragrance, aromatherapy, and flavor of food. Essential oils are collectively referred to as volatile hydrophobic oils extracted from plants. Essential oils can be obtained mainly by distillation or solvent extraction. Essential oils include Cassia oil, Cinnamon oil, Sassafras oil, Allspice oil from fruit, Juniper oil, Juniper oil, Cannabis oil, Chamomile oil, Clary sage oil, Clove oil, Scented geranium oil, Hops oil, etc. can be obtained from flowers. ), Hyssop oil, Jasmine oil, Lavender oil, Manuka oil, Marjoram oil, Orange oil, Rose oil ), Ylang-ylang oil, Basil oil, Bay leaf oil, Buchu oil, Cinnamon oil, Common sage oil, Common sage oil, Eucalyptus oil, Guava oil, Lemon grass oil Lemon grass oil, Melaleuca oil, Oregano oil, Patchouli oil, Peppermint oil, Pine oil, Rosemary oil, Spearmint oil, Bergamot oil, grapefruit oil, etc. extracted from sesame oil, Speamint oil, Tea tree oil, Thyme oil, Tsuga oil, Wintergreen oil and shell, Grapefruit oil, Lemon oil, Lime oil, Orange oil, Tangerine oil, Benzoin oil, Copaiba oil, ), Frankincense oil, Myrrh oil, Galangal oil extracted from rootstock, Ginger oil, Valerian oil extracted from roots, Anise oil, buchu oil, celery oil, rye oil, Cumin oil, Flax oil, Ntmeg oil, camphor oil, cedar oil, rosewood oil, ), Sandalwood oil, and agarwood oil. Especially, eucalyptus oil is used as an additive to detergents to keep fresh fragrance continuously. Lavender oil is added to fragrance or used as a insect repellent.

These fragrance oils can be mixed with polymers to form emulsions, which can be used for dog pads, bathroom fragrances, and bathroom fragrances. However, there is a problem in that the emulsion can not be stored for a long period of time because phase separation occurs with the lapse of time and the particle size becomes large. Therefore, an emulsifier is essentially added to produce a stable emulsion. Lecithins, Sodium Dodecyl Sulfate, Polysorbate 20, Tween 20, Polysorbate 80, Tween 80, Poloxamers, The emulsion is stabilized by the addition of an emulsifier such as whey protein (Whey Protein Isolate, Arabic Gum, Soybean Soluble Polysaccharide).

There are various methods for controlling the vaporization rate of conventional fragrance oils, and they are applied to various products. Aromatherapy heats the fragrance oil to increase the rate of vaporization, and the diffuser controls the rate using a base alcohol or lead stick. Also, in order to reduce the vaporization rate of the fragrance oil, nanoparticles, capsules or films can be prepared and the rate of vaporization can be controlled. Thus, a method of imparting antibacterial property by adding fragrance oil to the film is also used. On the other hand, a method of producing a fragrance oil nanocapsule such as a chitosan capsule, a melamine capsule and a cellulosic capsule is widely used. However, such a method requires that the melamine-based capsule be crushed and crumpled before the fragrance is produced, And the fragrant film is often unable to function. In addition, there are problems in that a process for producing a melamine-based capsule is complex and toxic waste is generated in the process.

In particular, the fragrance oil used for the dog pads, the toilet fragrance, and the bathroom fragrance to eliminate or reduce the odor is odoriferous, and the condition that the fragrance oil does not volatilize in the dry state without moisture in the bathroom, The vaporization rate of the fragrance oil needs to be adjusted so that the fragrance is obtained only when it is satisfied.

As a result of the experiment, when the concentration of corn starch was 1% (w / v) or 2% (w / v), the oil volatilization rate after 2 hours was 15-16% and the concentration of corn starch was 3% ), The fragrance oil volatilization rate is less than 15%. When the water-soluble polymer is corn starch, the concentration of 1% (w / v) to 3% (w / v) has the optimum fragrance oil volatilization rate in the present experimental example. That is, corn starch can be used as a water-soluble polymer of a fragrance oil porous particle composition which limits the volatilization rate of fragrance oil in the air according to the present invention.

In this Experimental Example, a polymer aqueous solution was prepared at a concentration of 1% (w / v) of a water-soluble polymer (3% (w / v) in case of cornstarch) To prepare a particle composition. 100 mg of each of the prepared compositions is placed in a vial, and 1 mL of water is added. After 2 hours, the fragrance oil volatilization rate is measured. In addition, a fragrant oil porous particle composition is prepared with water-free hydroxypropylmethyl cellulose (HPMC, hereinafter referred to as HPMC), and the fragrance oil volatilization rate is measured after two hours.

Gas chromatography-mass spectrometry (GC-MS) experiments were conducted to quantify linalool, a major component of lavender oil, by adding 2 mL of methanol to each sample and extracting lavender oil overnight. The column was equipped with a DB-WAX Capillary GC Column (30m, 0.25mm, 0.25um), splitless injection method, port temperature of 80 ℃, transfer line temperature of 240 ℃ and scan mode (Solvent delay: 3 min) Respectively.

FIG. 8 is a graph showing the preparation of a porous particle composition of lavender oil stabilized by a water-soluble polymer while changing a water-soluble polymer, and measuring the amount of lavender oil released after two hours in air and water.

As a result of the above experiment, when the gabapul or sodium alginate was used as a water-soluble polymer, lavender oil, which is a fragrant oil, was released by 50% or more in five hours in the nucylline US2 composition of the stable lavender oil by the water-soluble polymer. 100% released. On the other hand, nucile of lavender oil stabilized by a water-soluble polymer made of starch, carboxy methyl cellulose (CMC), natural cellulose, carrageenin, chitosan, aloe vera gel The US2 composition contained less than 20% of lavender oil in the air for two hours when left in the air. In the case of water, lavender oil was dissolved in the nucylline US2 composition of stable lavender oil by a water-soluble polymer made of starch and sodium alginate Over 90% of the time was released. However, in the case of carbomers, about 60% was released in water and not released in HPMC at all. That is, the porous particle composition of the fragrance oil stabilized by the water-soluble polymer according to the present invention has a release control system in which the fragrance oil is not released when stored in the air and the release is started when the fragrance oil is contacted with water.

The results are shown in Table 1. The results are shown in Table 1. In the present Experimental Example 1, in the same manner as in Example 1 except that limonene, citronella, peppermint, eucalyptus, rosemary, cinnamon, frankense, rose geranium, lavender, phytoncide, ultra- Lt; RTI ID = 0.0 &gt; oil-porous &lt; / RTI &gt; particle composition. Then, the fragrance oil volatilization rate was measured in the same manner as in the above-mentioned 2. Experimental Example 1 for two hours.

As a result of the experiment, limonene, citronella, peppermint and eucalyptus oil had a fragrance oil volatilization rate of 50% or more after 2 hours, while 20% or less of lavender, phytoncide, ultra dauny, tea tree and ylang ylang oil. That is, the fragrant oils may be used as the fragrance oil of the fragrance oil porous particle composition according to the present invention.

10 is a graph showing volatilization rates of fragrance oil according to the hygroscopic porous particles of the fragrance oil porous particle composition according to an embodiment of the present invention.

In this experiment, a mixture of palm oil activated charcoal, charcoal powder, zeolite, volcanic ash, ethylene vinyl acetate foam (hereinafter referred to as EVA), micro silicagel (product name: Syloid F244, F244), nucyline US2 was used to prepare a fragrance oil porous particle composition as in Example 1 above. Then, the fragrance oil volatilization rate was measured in the same manner as in the above-mentioned 2. Experimental Example 1 for two hours.

As a result of the above experiment, about 3% and 14% volatilization was obtained in charcoal powder and nucilin US2 composition, and about 40-60% in zeolite, volcanic ash and silyloid F244 composition. In the case of palm oil activated carbon and foamed EVA, about 70-90% of lavender oil was volatilized. Therefore, a fragrance oil porous particle composition can be prepared which can control the volatilization rate of the fragrance oil most effectively by using charcoal powder and nucilin US2 among the hygroscopic porous particles.

Referring to FIG. 11, FIG. 11 (a) is a photograph immediately after the preparation of an adhesive containing an fragrant oil-porous particle composition stabilized by a water-soluble polymer according to an embodiment of the present invention. Fig. 11 (b) is a photograph of the adhesive after 100 days passed. As a result of the test, the adhesive of the present invention was stable without phase separation even after 100 days, and showed the same property as glue.

Next, the adhesive according to the present embodiment was applied to the surface of a white paper coated with polyethylene at the top and coated with silicone at a thickness of 0.3 mm, and after 1 minute, the adhesive was applied to PSTC-6 section 4.2 and ASTM D3121 section 6.1 measurement standard The initial tackiness of the tape cleaner sample was measured using a Rolling Ball Tack Tester (RBT-BALL, Fairfield, Ohio). Here, the ball tack value is a value obtained by testing the tackiness of an adhesive or an adhesive tape. It is a value obtained by measuring the adhesive force of the adhesive or the like from a stop length and a ball size by rolling a ball at an arbitrary angle at a predetermined position.

Referring to FIG. 12, glue which has not been subjected to any treatment shows a ball tack value of 8.3 cm, glue which is an acrylic adhesive to a porous particle composition of corn starch stabilized by corn starch including ylang ylang and lavender oil has 9.2 and 9.1 cm ball tack value, which is the same within the error range as for the untreated glue.

Therefore, as a result of the above experiment, it is possible to produce an adhesive including a fragrance-oil porous particle composition in which volatilization rate of fragrance oil is controlled by contact with water.
