Description

Oil-in-Water Solid Type Low Irritation and High Moisturizing Cosmetic Composition Comprising Polyol and Emulsifier and Manufacturing Method Thereof}

The present invention relates to low irritant and high moisturizing cosmetic compositions comprising an excess of polyol and a minimum amount of emulsifier.

When the excess polyol (5-40%) is contained, emulsified particles are formed by forming a lamellar liquid crystal through hydrogen bonding between the hydroxyl group of the polyol and the hydroxyl period of the emulsifier to solve the disadvantage of sticking and affecting the emulsion stability. It can prevent the formation of the gel-network that can contribute to the stability and hard viscosity of the emulsion to achieve an excellent long-term phase stability emulsification system, skin-friendly polyol component can increase the moisturizing power.

More specifically, the present invention is a low irritant and highly moisturizing cosmetic composition, consisting of an oil-in-water emulsion, 50-80% by weight of an aqueous phase containing a polyol component and a natural emulsifier of a wax or oil component and a sucrose cocoa derivative derivative structure It relates to a hypoallergenic and highly moisturizing cosmetic composition composed of 20-50% by weight of an oil phase including

In addition to the basic features that protect human skin from external stimuli, it is also closely related to beauty. In particular, the skin color represents the most fundamental phenomenon of skin beauty, and a lot of researches on the mechanism for controlling the skin color are progressing in the cosmetic industry. The pigments that affect skin color include melanin, carotene, and hemoglobin, the most important of which is melanin. The biggest factor affecting the biosynthesis of melanin is ultraviolet rays and hormones in the body. Melanin plays an important role in preventing or damaging the skin from ultraviolet rays by absorbing or scattering ultraviolet rays, and absorbs light in all areas without a specific maximum absorption wavelength. In addition, the function of removing active oxygen species is excellent, but sometimes melanin itself generates free radicals, and other substances are reduced or oxidized by catechol or quinone in melanin structure, and melanin itself shows the properties of free radicals. Pray. In recent years, the technology for preventing aging is mainly directed to preventing skin pigmentation by promoting collagen synthesis or inhibiting melanin biosynthesis.

Human skin has a barrier function that protects the body from various external stimuli and prevents moisture from the inside. To this end, the epidermal layer of the skin develops into a thin stratum corneum while containing moisture through the process of differentiation. Structurally, the cells of the stratum corneum act like bricks, and the intercellular lipids of the keratinocytes act as a mortar, forming the skin barrier.

However, as people age, dry skin tends to increase, and the need for skin moisturizers increases due to indoor heating and air pollution. To this end, polyhydric alcohols and sugars as skin moisturizers have been used in cosmetics as general moisturizers. However, there is a drawback that the stickiness occurs on the skin, there is a problem that does not give sufficient moisturizing effect to the skin, and also does not give a continuous moisturizing effect. In addition, in the summer when the humidity is very high, rather than draw moisture from the outside, the skin is sticky, in the winter, the humidity of the outside atmosphere is low, rather draw the moisture from the skin, rather the problem of drying the skin occurs.

Human skin is very sensitive to relative humidity and usually has a pleasant feel when the relative humidity is 40-70%. Relative humidity is the ratio of saturated water vapor in% at the same temperature as 1 m ³ of air in the air. In Korea, the humidity is very high in summer and the humidity is very dry in winter. People's skin is also affected by seasonal changes and changes in humidity. It is uncomfortable in summer with high temperature and humidity due to high temperature and humidity, and low in relative humidity in dry winter, causing lips and skin to become dry and sometimes cracked or sometimes difficult to breathe. I feel it. When the relative humidity is high, the moisture in the air is absorbed and becomes sticky. On the contrary, when the relative humidity is low, the moisture of the skin is evaporated and dried. In particular, when the relative humidity is low, the dryness of the skin is often accompanied by pulling and itching.

In order to improve dryness of the skin, various cosmetic compositions using various moisturizing agents such as oils, sugars and polyols have been developed. For example, by using the skin components such as ceramide, cholesterol, fatty acids, etc., the skin barrier function is strengthened to suppress moisture evaporating from the skin, or sugar, polyol, etc., which has a strong ability to bind with water on the surface of the skin, thereby improving skin moisture retention ability. To enhance the moisturizing effect of the skin. However, it is difficult to sustain the effect for a long time in winter when the relative humidity is low, and in the summer when the relative humidity is high, rather uncomfortable, there is a difficulty in preparing a suitable cosmetic composition according to the change in relative humidity. Also, many skin-related products contain substances that can cause irritation or inflammation, and more than 10% of people who use personal care products complain of side effects on their skin. The number of consumers who feel that their skin is sensitive is on the rise. More than 30-40% of respondents say they are sensitive skin in a consumer survey, and this trend continues to increase. Moreover, recent cosmetics are focused on the functional cosmetics (cosmeceutical) that can have a real effect on the skin, so skin side effects due to the use of personal care products such as cosmetics is expected to increase gradually. In particular, the environmental pollution is severe and the skin is easily damaged due to the increase in the amount of ultraviolet radiation due to the destruction of the ozone layer, the drying of the living space, the constitution of the individual's allergies, the stress, and the increase of chemical harmful substances. Therefore, the skin becomes easily reddened or sensitive. Generally, various raw materials are used to make cosmetics, and usually 20 to 50 raw materials are used. These ingredients have been proven to be safe through skin irritation tests, but they can be applied to products that can cause irritation, itching and allergies to the skin. Skin irritation that may occur with the use of cosmetics includes irritation such as itching, stinging and burning, and erythema and edema. Contact dermatitis may be roughly classified into irritating contact dermatitis, allergic contact dermatitis, sensory stimulation and phototoxic dermatitis, but it is difficult to clearly distinguish them.

Recently, in the case of emulsified emulsions used in cosmetics, in addition to the basic skin protection function, various additional functions such as sun protection and skin improvement function are considered important, and various harmful substances due to environmental pollution and pollution are applied to the skin. With increasing interest in the effects of the skin, consumers are more responsive to hypoallergenic emulsifying cosmetics with less skin irritation, but many products are on the market. Until now, hypoallergenic products are used to reduce irritation or to reduce skin irritation. It was common to limit the amount of raw materials and their amount, and as a result, the usability of the product was reduced and the skin improvement effect using the functional raw materials was limited. Examples of substances that cause skin side effects include preservatives, emulsifiers, oils, and skin-improving substances.In order to minimize their irritation, they are more effective than oil-in-water cosmetics that add these substances to the trauma to minimize direct contact with the skin. It is currently applied to oil-based cosmetics added to merchant oil phase. Among them, preservatives are being improved by reducing the production of preservatives and improving natural preservatives by improving the production and manufacturing facilities.In the case of oils, ester-based oils that can cause skin side effects have been developed due to the development of various kinds of silicone oils with excellent usability. And animal-based oils, etc. are being replaced a lot. However, even in these hypoallergenic compositions, an emulsifier should be included in an amount of about 3-10% for stability of the product. However, in recent years, efforts have been made to minimize the content of such emulsifiers, but in most cases, unstable emulsification conditions cause instability, severe changes over time, and contents harden after a long time. It was difficult to develop.

Patents or academic literature that improved the moisturizing feeling using various types of polyols, such as KR Patent Publication No. 10-2010-0109783 (name of the invention: cleansing and exfoliation, composition of moisturizing natural cosmetics) can be easily searched. No literature has been found to address the problem of stickiness due to overuse of skin and skin irritation caused by the use of emulsifiers.

Numerous papers and patent documents are referenced and cited throughout this specification. The disclosures of the cited papers and patent documents are incorporated herein by reference in their entirety to better understand the state of the art to which the present invention pertains and the content of the present invention.

The present inventors earnestly researched to develop an oil-in-water cosmetic composition that can reduce the skin irritation by minimizing the content of the emulsifier and have a good feeling, as well as high emulsion stability. As a result, hydrogen bonds between the hydroxyl groups of the polyols and the hydroxyl period of the emulsifiers are included when they contain 5-40% by weight of polyol, 0.01-5% by weight of emulsifier and 10-30% by weight of wax or oil component, based on the total weight of the cosmetic composition. The present invention has been found to facilitate the formation of a gel-network that may contribute to the stability and hardness of the emulsion by preventing the emulsion particles from coalescing by forming a liquid crystal of the lamellar structure through.

Accordingly, it is an object of the present invention to provide a low irritant and high moisturizing oil-in-water cosmetic composition containing an excess of polyol and emulsifier.

Another object of the present invention is to provide a method for preparing the low irritation and high moisturizing oil-in-water cosmetic composition.
