Description

The cosmetic composition for moisturizing comprising the mixture of extract of flower of Rhododendron mucronulatum var. lucidum Nakai, Malus pumila var. dulcissima and Magnolia sieboldii}

The present invention relates to a cosmetic composition for moisturizing and stimulating skin, and more particularly to a skin moisturizing or stimulating cosmetic composition containing a petal extract having a moisturizing effect and skin irritation-releasing activity.

Human skin must have the right amount of water to look soft, supple and healthy. This requires that the moisture evaporation be kept low even in a dry environment. Skin moisture balance is controlled by the epidermis. The stratum corneum of the epidermis is the accumulation of dead cells, but plays a very important role in maintaining skin moisture. The human body is composed mostly of water, which plays an important role in maintaining life. Moisture in normal skin is 70% in the body and 20% in the stratum corneum to support the elasticity and flexibility of the skin. If the moisture in the stratum corneum is less than 10%, the skin is known to dry out and cause skin problems. The amount of moisture in the stratum corneum produced by regular keratinization is always 10 to 20%.

Skin is classified into three types: normal, dry and oily. Skin types are classified by the condition of the skin surface, which is determined by the amount of NMF and sebum. If the amount of NMF and sebum is well balanced, the skin stays moist and soft. On the other hand, excessive sebum secretion can lead to oily and acne-prone skin. This type of skin is called oily skin and the pores of the skin come to the surface. On the contrary, if the amount of sebum is too small, the skin cannot keep the skin hydrated. Well-balanced skin is called normal skin and lies between oily and dry skin. In addition, as the skin ages, the amount of sebum secretion decreases, making it easier to become dry skin. The balance of water in the skin is related to the water binding power of the stratum corneum, the rate of water supply to the inner layer of the stratum corneum, and the rate of water loss on the outer surface of the skin. The stratum corneum of the epidermis is also located on the outermost side of the skin and suppresses the loss of moisture and electrolytes outside the skin, thus preventing the drying of the skin and providing a normal biochemical metabolism of the skin. It also plays an important role in protecting the human body from external physical damage and chemicals or preventing the invasion of bacteria and viruses into the skin (EliasPM .; JInvest. Dermatol., 80, pp 44-49, 1983).

Currently, a method of maintaining water in the skin is using an occlusive agent, which is a hydrophobic substance that promotes water retention by forming a barrier on the skin that prevents water loss. The most commonly used occlusion agents include petrolatum, lanolin, cocoa butter, mineral oil and silicone. In addition, to make cosmetics, 20 to 50 different raw materials are generally used such as sodium lauryl sulfate, dimethyl sulfoxide, croton oil, sodium hydroxide, etc. These ingredients can be applied to products that can cause irritation, itching, and allergies to the skin.

On the other hand, Rhododendron mucronulatum is a deciduous shrub of the Rhododendron azalea, also known as a real flower or a head of azalea. It grows in herds in the mountains of 50 ~ 2000m high in the whole country. Its height is 2 to 3 m and many branches are divided at the upper part of stem. The twig is light brown and has scales. Flowers bloom before the leaves in April and come out one by one from the side of the end of the branch. Corollas are open funnels, 4-5 cm in diameter, reddish purple or light red, with hairs on the outside, split into 5 ends. In oriental medicine, flowers are used as a medicine called Yeongsanhong (迎 山 紅), which is effective for headaches caused by seawater, bronchitis, and cold, and has a diuretic effect.

The apple tree (Malus pumila) is a rosaceae rosaceae and grows up to about 3-10 m in height. Twigs are purplish. Leaves are alternate, oval or egg-shaped, serrated at the edges and hairy over the veins. The flowers run in inflorescences in April-May, and white flowers come out of the leaf axes with the leaves.

In addition, the Magnolia sieboldii K. Koch is a plant belonging to the Magnolia Magnolia family, which has a white flower at the end of its branch after the leaves emerge. The diameter of the flower is smaller than that of the common magnolia, and the flower is prone.

Peach blossoms are also bloomed in the Prunus persica, which belongs to the genus Rosaceae. Peach blossoms bloom in April-May, before they bloom. Flowers bloom in old branches.

< Experimental Example  1> Moisturizing effect experiment of petal extract

The skin moisturizing improvement effect of the cosmetic composition of the extract of Examples 1 to 6 was measured in animals.

Acetone is applied to the back of young hairless mice 8 to 10 weeks after birth periodically for 5 days to impair the barrier function of skin such as experimental animals, and then 40 g of TEWL is measured using the evaporimeter. Only for experimental animals having skin showing percutaneous moisture loss of / m 2 / hr or more, the composition of Examples 1 to 6 was continuously applied twice a day for 3 days at a dose of 200 μl per 5 cm ² of skin area for a predetermined time. TEWL was measured every time. The amount of water evaporated from the skin was calculated according to the area and time, and the amount of water evaporated was read by the temperature and moisture electronic sensors, and the TWEL measurement to measure the moisturizing power of the skin was quantified by the following method.

After the temperature and humidity are kept constant and only a small number of people are left (preferably blocking the flow of air) besides the meter and the subject, the TEWL probe is placed on the subject's measuring area. After that, do not apply excessive force to the measuring part and place it lightly (not to leave marks on the skin) and make an angle of 90 degrees with the ground. Then, the value of the skin's TEWL level becomes constant over time (usually 1-3 minutes). Hold the probe's handle as far as possible to prevent the body temperature from being transferred. Thereafter, the amount of water evaporated per hour per area (g / m 2 / hr) is calculated.
