Description

Natural essential oil composition for skin application to improve skin blood flow and cosmetic composition comprising the same

The present invention relates to a natural essential oil composition and a cosmetic composition comprising the same, and more particularly, it contains natural essential oils such as ginger oil, jasmine oil, and sweet orange oil to have a fragrance preference, no skin irritation, and skin capillaries. It relates to a natural essential oil composition for skin application that expands and improves blood flow to the skin, and a cosmetic composition comprising the same.

The purpose of cosmetics is to maximize the beauty by making the skin beautiful in appearance. Raw materials with various effects such as whitening, wrinkle improvement, and skin protection are screened and added during cosmetic manufacturing. Among them, the effect of improving skin blood flow is to make dull and inelastic skin fresh, clear and transparent through smooth blood flow improvement of the skin, making healthy skin that stands out in appearance.

Blood flow generally refers to the flow of blood caused by the gradient of blood pressure in the vascular system inside the body. Smooth circulation of blood flow in the body is essential for maintaining a normal state of the human body. By measuring and analyzing the blood flow volume of the subcutaneous blood vessels, it is possible to determine whether the blood flow is circulating smoothly, and through this, the health status of the body can be checked.

Blood flow measurement in a living body is divided into an invasive method and a non-invasive method in vitro. As an invasive method, a volume method to obtain the volume of flowing blood by cutting a blood vessel, a dynamic pressure method to obtain by placing an object in a flow and measuring the force that the object receives due to a change in the momentum of the flow, and a fluid flowing in a magnetic field There is a method using an electromagnetic flowmeter, which is obtained from the electromotive force generated by

As a non-invasive method, there is an ultrasonic blood flow Doppler method and the like. A measurement method using the Doppler effect has been used as a method for non-invasively measuring the blood flow velocity in blood vessels inside the human body. The Doppler effect is a physical phenomenon that when a wave is incident on a moving object, the frequency shift of the scattered wave is proportional to the speed of the object. The basic principle of the method of measuring the speed of blood flow using a Doppler beam is to measure the shift frequency when the reflected wave signal of ultrasound from a reflector (blood cell) in the blood receives a frequency shift due to the Doppler effect. do.

However, the skin temperature of the human body has the greatest influence on the blood flow internally. When the external environment is kept constant, the increase in skin temperature is evaluated as a physiological improvement of the skin as a result of active metabolism. Due to lack of sleep, stress, etc., the balance of the autonomic nerves is disrupted, and blood circulation deteriorates. As a result, the blood does not reach the periphery sufficiently, and the supply of oxygen and nutrients is blocked, and waste products and water accumulate. This lowering of metabolism affects skin fatigue recovery function, deterioration of complexion, and aging. Therefore, measuring the blood flow in the facial area is the basis for objectively evaluating changes in skin condition.

On the other hand, as the skin ages, keratinization and fusion of epidermal cells gradually slows down, and the epidermal cell layer becomes thin while the stratum corneum becomes thick, and the boundary with the dermal layer becomes smooth. In the dermis, fibroblasts age and the ability to produce fibers and matrix decreases, and as skin cells age, peroxide levels in the cells increase rapidly, and they are easily affected by various contaminants and stress.

In addition, due to skin aging, the components of cells and cell membranes are changed to peroxides, and protein damage occurs, and the cells cannot perform their functions smoothly, so that the metabolic activity of the cells is reduced, and wrinkles are generated due to this functional and structural damage. Because of these, skin aging is further accelerated. Blocking the steps involved in these skin aging mechanisms is a way to fundamentally prevent skin aging, and it will be important to fundamentally heal skin by improving blood flow.

However, substances having the effect of improving blood flow are extremely limited or not many types of substances are known, and a small number of substances currently used are chemically synthesized and used.

However, recently, the efficacy of aromatherapy has been continuously studied. Aromatherapy is a combination of 'aroma' meaning fragrance and 'therapy' meaning treatment. Aromatherapy is known to exhibit psychological, physical, and skin cosmetic effects using essential oil extracted from plants.

The basic principle of aromatherapy is that the fragrance particles of essential oil stimulate the olfactory nerve of the nose and are transmitted to the brain to show mental effects, and the essential oil absorbed into the skin is absorbed into blood vessels or organs to show physical effects. Aromatherapy mainly uses methods such as inhalation or massage through the nose. Stimulation through the sense of smell induces human emotions, and massage is actively used in the beauty field by combining physical and mental effects.

However, there are no related studies on the effect of improving blood flow when the essential oil applied to aromatherapy is directly applied to the skin. In particular, when the essential oil composition is directly applied to the skin, skin irritation is severe, individual differences in palatability are large, and even in that case, it is known that satisfactory effects are not obtained.

Korean Patent Registration 2016-0037304, Composition for improving skin blood circulation containing chamomile flower powder

The present invention is to solve the problems of the prior art, and an object of the present invention is to provide a natural essential oil composition for skin application that derives a significant skin blood flow improvement effect.

Also in this case, the present invention is to provide a natural essential oil composition for application to the skin having a high fragrance preference and no skin irritation.

The natural essential oil composition for skin application according to the present invention is characterized in that the essential oil is directly applied to the skin to derive the skin blood flow improvement effect.

At this time, the present invention was constructed in consideration of the balance of top notes, middle notes, and base notes in consideration of not only the increase in skin blood flow, but also the chemical components, fragrance, volatility, skin irritation, and precautions of essential oils. Each essential oil is preferably blended to a set amount and refrigerated until use.

In addition, it is preferable that the top note is sweet orange, the middle note is ginger oil, and the base note is any one selected from jasmine oil, ylang ylang oil, and frankincense oil.

Here, the main components of sweet orange (Citrus sinensis) are monoterpenes such as limonene, beta-myrcene, and alpha-pinene. Essential oils containing a lot of monoterpenes have a small molecular weight, are highly volatile, have a light top note fragrance, and are easily oxidized.

Sweet orange oil is an orange-colored liquid obtained by extracting the peel of orange sweet by pressing, and has a psychologically warm, bright and refreshing effect. It is safe because it is less likely to cause phototoxicity [a skin reaction that occurs in the presence of ultraviolet light, due to the property that the furocoumarine component of essential oils (mainly contained in citrus fruits) absorbs more light].

However, as a top note, sweet orange is a light and fresh fragrance that is added for the quenching effect that secures palatability such as fragrance preference and suppresses potential side effects caused by various components of essential oil as a relatively safe oil. It is preferable, but in order to induce direct blood flow improvement, it is preferable to further include an essential oil of middle note, which has an effect of promoting body metabolism and function. Accordingly, the present invention is characterized by adding ginger oil, which is an essential oil that stimulates circulation as a middle note.

In addition, in the present invention, it is preferable to further include the essential oil of the base note in order to serve as a fixing agent for imparting durability, depth, and strength by fixing the blending to the skin.

Ginger oil is a yellow liquid obtained by steam distillation of the root rhizomes of ginger, which stimulates circulation and helps relieve vascular problems. Ginger oil psychologically warms, relieves joint pain and muscle pain symptoms, relieves varicose veins and vascular problems such as cold hands and feet, helps the digestive system, and helps with respiratory symptoms such as cold symptoms. have.

The main chemical components of ginger oil are sesquiterpenes such as zingiberene and alcohols such as zingiberol and gingerol. This oil warms the body and mind and stimulates circulation, which can help relieve varicose veins, cold hands, and frostbite. It has a sterilizing action and is effective for phlegm, a cold, a fever, and a sore throat. It promotes circulation, warms the body, and has beneficial effects such as reducing pain and inflammation in rheumatism and arthritis.

At this time, the natural essential oil composition for skin application according to the present invention is applied to the skin using ginger oil as a middle note of the essential oil to further increase blood flow. However, since ginger oil may be irritating to the skin, it should be diluted at a low concentration and used, so it is preferable to contain sweet orange oil so that the content of sweet orange oil is 1.5 to 2.5 times that of ginger oil to alleviate skin irritation. At this time, when the content of sweet orange oil is more than 2.5 times that of ginger oil, the effect of increasing blood flow is saturated, so the upper limit is limited.

At this time, the base note may be any one selected from jasmine oil, ylang ylang oil, and frankincense oil. In terms of fragrance preference, the base note is preferably jasmine oil, and in terms of skin irritation, frankincense oil is preferable. .

Jasmine oil is a yellow liquid obtained by solvent extraction of jasmine flowers and has the effect of calming nerves and warming emotions. , has the effect of relaxing the stress state and normalizing the hormonal balance, and has been reported to be non-irritating and non-irritable. Frankincense oil is a pale yellow to green liquid obtained by steam distillation of boswellia species. It is generally reported as insensitivity.

At this time, the content of sweet orange oil, which is the top note, is preferably formed to be greater than the content of the oil included in the pre-basic oil or the base note for fragrance preference, and as described above, in consideration of skin irritation further, the top note, middle note and base The weight ratio of the notes is preferably 1.5:1:1 to 2.5:1:1.

On the other hand, the essential oil composition according to the present invention penetrates into the dermis of the skin to increase blood flow. In this case, the increase amount may be 0.01 or more. Therefore, it is possible to derive an immediate blood flow improvement effect.

In addition, the essential oil composition according to the present invention can be formulated for external application for skin such as perfume or cosmetics, and the formulation of the cosmetic composition is a pack, ointment, lotion, solubilized burn, suspension, emulsion, cream, gel, spray, patch, It may be any one selected from a warning agent, a patch agent, and a water paste.

The natural essential oil composition of the present invention has an effect of improving blood flow to the skin, satisfies the fragrance preference of aromatherapy, and minimizes irritation when applied to the skin. Accordingly, the natural essential oil composition according to the present invention can be widely used in various fields such as cosmetics and external preparations for skin.

1 is a view showing the blood flow increase rate of a natural essential oil composition according to an embodiment of the present invention.
