Description

A composition containing Cacalia extract as an active ingredient that does not irritate the skin and provides excellent skin moisturizing {A COMPOSITION THAT DOES NOT IRRITATE THE SKIN AND HAS EXCELLENT SKIN MOISTURE CONTAINING THE EXTRACT OF EMILIA COCCINEA}

The present invention relates to a composition containing Cacalia extract as an active ingredient, which does not cause skin irritation and has excellent skin moisturizing effect.

The skin is the largest organ in the body and is always in contact with the outside world. It acts as a protective layer that protects the living body from various stimuli or dry environments. Compared to other organs, the skin is an organ where the creation and extinction of new cells occurs more actively. It also plays a very important role in protecting against physical abrasions, preventing the loss of water in the body, protecting against harmful ultraviolet rays from the sun, and regulating body temperature. Baby's skin is generally white, soft, and free of inflammation such as acne. However, baby skin is never as good as adults think is ideal. Rather, due to its extremely immature state, the stratum corneum that forms the border with the outside is thinner than that of an adult, and the moisture content of the stratum corneum and the protective barrier function of the epidermis, which is one of the important functions of the stratum corneum, are weak. For this reason, baby skin is sensitive to external influences and can be easily exposed to viruses. As such, baby skin is prone to dry skin, and this dry skin can weaken immune function, which can lead to not only atopic dermatitis but also various skin diseases. Similarly, the weaker and more sensitive the skin is, the more urgent it is to strengthen anti-inflammatory and skin irritation-relieving functions.

In general, many products applied to the skin contain substances that can cause irritation, inflammation, or allergies, so more than 10% of people who use personal care products complain of side effects on the skin. A survey of consumers in the United States in the 1990s found that more than 50% considered themselves to have sensitive skin. Moreover, as recent cosmetics tend to focus on functional cosmetics that can have real effects on the skin, skin side effects due to the use of personal care products such as cosmetics are expected to increase.

The factors that are causing the increase in the proportion of people feeling that they have sensitive skin include increased ultraviolet irradiation due to ozone layer destruction, drying of living spaces, individual allergic constitution, stress, and increase in chemical harmful substances. On the other hand, recent consumer trends It is presumed that this transition to a nature-friendly and hypoallergenic diet is also a factor in improving awareness of sensitive skin. Therefore, interest in substances that relieve irritation from cosmetics is increasing.

Recently, as people's living standards have improved, interest in and demand for skin-related functional cosmetics has been rapidly increasing. However, as side effects related to functional cosmetics made of synthetic materials continue to be raised, research on the development of cosmetics using effective and non-toxic natural products is being actively conducted. there is. Cosmetic development research using natural products requires continuous development of functional natural products as part of the discovery of effective cosmetic materials that are safe, do not irritate the skin, and improve skin moisturization.

Accordingly, there is a need to develop a cosmetic composition that contains natural extracts, has no problems with side effects, does not cause skin irritation, does not cause discomfort in use, and has excellent skin moisturizing effects.

A functional food composition for skin moisturizing according to another embodiment of the present invention includes the skin moisturizing composition.

Hereinafter, the present invention will be described in more detail.

In the human body, the skin is an organ that functions as a protective film that protects the living body from the external environment. It prevents the loss of biological components in the human body, such as water and electrolytes, and also prevents harmful substances from entering the human body from the outside. do.

This skin is largely divided into the epidermis layer, dermis layer, and subcutaneous fat layer. The epidermal layer is composed of keratinocytes and melanocytes. The outermost keratinocyte layer of the skin is in direct contact with the external environment, so it requires strong resistance to physical, chemical, or material penetration, and prevents moisture loss from the human body to the outside. It must maintain flexibility by retaining adequate moisture while simultaneously shrinking.

In general, the moisture content of the skin is about 70% in the dermis layer, but decreases toward the epidermis layer, reaching about 10 to 30% in the keratinocyte layer. Water supplied from the dermal layer mainly moves to the upper part of the stratum corneum by passive diffusion and is ultimately discharged to the outside.

This is called Trans Epidermal Water Loss (TEWL), and it is known that the sebum component and epidermal lipid, which are lipid membrane components of the keratinocyte layer, maintain this transepidermal water loss at an appropriate level. In addition, it is known that the keratinocyte layer contains a hydrophilic substance with water-retaining ability called Natural Moisturizing Factor (NMF), which plays an important role in moisturizing the skin.

When the moisture content of the normal keratinocyte layer is maintained at about 10 to 30%, the skin is smooth and soft and functions to protect the body normally. However, when the moisture content of the keratinocyte layer falls below 10%, the skin becomes rough and loses its protective function, causing aging.

For example, in the case of dry skin, the cohesion of keratinocytes is weakened and a scaling phenomenon occurs in which keratinocytes peel off from the skin surface like scales. This drying of the skin is due to the moisture content of the keratinocyte layer. This is because it is less than normal skin.

In addition, even if the skin is healthy, the skin condition may worsen due to lack of moisture due to harsh external environments, such as wind, cold weather, sunlight, washing the face, and shaving.

Therefore, it is very important to maintain the appropriate moisture content of the skin's keratinocyte layer. It is known that when the moisture content of the stratum corneum is less than 10%, the skin becomes dry and causes skin problems. The amount of moisture in the stratum corneum created by regular keratinization is always maintained at 10 to 20%.

Currently, occlusive agents are used to retain moisture in the skin. Occlusive agents are hydrophobic substances that promote moisture retention by forming a barrier on the skin that prevents moisture loss.

The most commonly used occlusives 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. When these raw materials are applied to products, they can cause skin irritation such as inflammation, itching, and allergies.

The main characteristic of the composition of the present invention is that it does not cause skin irritation when applied to the skin and exhibits an excellent skin moisturizing effect.

A skin moisturizing composition according to an embodiment of the present invention includes Cacalia extract as an active ingredient.

The Emilia coccinea is an annual herb of the dicotyledonous plant Campanula Asteraceae, is native to India, and is cultivated as an ornamental plant. The leaves are alternate, long egg-shaped, have dull sawtooth edges, have no petioles, and look like they are powdered. The flowers bloom in an orange-red color from June to October, and a capitate flower (a flower made up of many small flowers without peduncles blooming at the end of a flower stalk, forming a head) hangs at the end of a thin flower stem. The capitol flower is composed of tubular flowers, and the corolla of the tubular flower is divided into five parts. The fruit is an achene. It is sown in spring and has strong properties. Cacalia is derived from the old genus name Cacalia, and is similar to the fireweed.

The extract may be extracted using any one selected from the group consisting of water, lower alcohols having 1 to 6 carbon atoms, and mixtures thereof as an extraction solvent.

Specifically, grinding dried Cacalia; leaching the pulverized material using an organic solvent; Leaching and drying the sample; Re-leaching the dried sample using an organic solvent; Leaching and drying the sample; Leaching using water; And including the step of leaching, a Cacalia extract can be obtained.
