Description

Low Irritant Powder Composition for Washing Containing Mung Beans Powder

The present invention relates to a powder composition for hypoallergenic face wash containing mung bean powder.

In general, the face wash is one of cosmetics for the purpose of cleaning the skin by removing the skin contaminants, such as excess sebum or waste, look at the skin contaminants in detail as follows.

Skin contaminants are classified into exogenous and endogenous contaminants. Exogenous contaminants include various chemicals in the air, dust, bacteria, and cosmetics used for skin, and endogenous contaminants include sebum, sebum altered substances and sweat. For example, various excreta and old dead skin cells may be mentioned. These pollutants adhere to the skin, propagate various germs, and damage the health of the skin, such as loss of normal sebaceous membrane function. In particular, sebum generates lipid peroxide by irradiation with natural light, and the lipid peroxide thus formed causes inflammation, swelling, pigmentation, etc. on the skin, which is harmful to the skin.

Therefore, the most widely used to remove skin contaminants such as sebum and waste products is a surfactant of a fatty acid soap, but it may cause skin pulling, itching, and skin roughening during face washing to reduce irritation to the skin. The use of hypoallergenic materials is on the rise.

Surfactants conventionally used to remove the skin contaminants include alkyl sulfates, alkyl ether sulfates, and higher fatty acid salts. However, these have been a problem for skin irritation such as skin pulling, itching, rough skin, etc., and milder hypoallergenic surfactants have been required.

The hypoallergenic materials are monoalkyl phosphate, acylated methyltaurine, sodium cocoyl isethionate, amino acid surfactants, etc. These components have lower skin irritation than skin soap or synthetic detergent components and have low skin penetration. It is estimated to be quite low.

On the other hand, excessive washing with the surfactant may unnecessarily remove the natural moisturizing component (NMF) and intercellular lipids in the skin, and may cause adsorption of the surfactant or fatty acid to the skin, etc. by an incorrect washing method. .

In addition, the expectation of skin cosmetic effects such as moisturizing beyond the face wash function, which is the main purpose of face wash, is a reality that is constantly required in the face wash composition.

The present invention is to solve the above problems, primarily to reduce the irritation as the main stimulating source of the surfactant as a small irritant to the skin using an amino acid-based surfactant and isethionate-based surfactants The present invention was completed by removing the skin contaminants without irritation by containing mung bean powder having a soothing and selective sebum removing ability of the skin and minimizing the cleansing effect.

Accordingly, an object of the present invention is to provide a powder composition for low-low polar skin cleansing containing an amino acid surfactant, an isethionate surfactant, and mung bean powder.

The present invention provides a face wash powder composition containing mung bean powder. The composition of the present invention reduces the primary irritation by using an appropriate ratio of amino acid surfactant and isethionate-based surfactant exhibiting a cleaning effect, and by adding mung bean powder, not only a soothing effect but also a higher cleaning effect and improved usability In addition, the stability of the preservative system can be improved to minimize the stimulus as much as possible.

The present invention relates to an amino acid-based surfactant, an isocionate-based surfactant, and a face-wash powder composition containing mung bean powder.

Amino acid-based and isethionate-based surfactants are widely known as representative hypoallergenic surfactants for washing, and are also known to be excellent in biodegradability. The proper combination of these two components will improve the usability along with high skin safety, enabling a mild cleansing powder with better cleaning effects. Preferred amino acid surfactants for use in the face-wash powder composition of the present invention include acyl amino acid sodium-based and potassium lauroyl glutamate, potassium myristoyl glutamate, etc. It is selected from the group consisting of an acyl amino acid potassium system, and sodium acyl amino acid type surfactant is more preferable. In addition, preferred isethionate-based surfactants for use in the face-wash powder composition of the present invention include ammonium cocoyl isethionate, sodium cocoyl isethionate, sodium lauroyl isethionate, and sodium myristoyl isethionate. And sodium oleoyl isethionate, with sodium cocoyl isethionate being more preferred.

In addition, the powder cleaning composition of the present invention contains mung bean powder to selectively remove sebum with skin soothing effect, leaving a large amount of keratinocyte-derived lipids, which are important factors for preventing skin roughness, sebaceous gland-derived lipids are contaminated with other skin A sufficient cleansing with the material will provide a skin cosmetic effect beyond simple cleansing.

Mung bean powder used as an active ingredient in the composition of the present invention is dried seed of mung bean (Phaseoulus radiatus L.), weak and nontoxic and sweet. The main components of mung beans are sugar (44.9%) and protein (21.2%), which are rich in essential amino acids such as leucine, lysine and valine, and are known to be excellent in nutrition because they contain a lot of unsaturated fatty acids linoleic acid. The Chinese herbal medicine "Honbibiyo" is said to remove the heat of mung beans, to release poison and benefit urine. In the "food herbal", mung bean is said to be good for refreshing and beautiful skin. As a result, it is said that the effect of the effect is already well known.

In particular, mung beans in the skin to lower the heat and detoxification effect is excellent, it is excellent for skin diseases such as sweat bands and acne.

 Korean Patent Registration Nos. 10-0161333 and 10-0463081 have already presented the efficacy and effects of mung bean extract in cosmetic compositions. However, since it is not possible to apply a large amount of mung beans as an extract due to the formulation characteristics of the powder-type cleaning agent as in the present invention, by applying a powdered mung bean to maximize the efficacy and effect by the mung beans.
