Description

TECHNICAL FIELD The present invention relates to a cosmetic composition for refrigeration storage, and a method for manufacturing a mask pack using the composition.

The present invention relates to a cosmetic composition for refrigeration storage which maintains a solid gel state at a refrigeration temperature and turns into a liquid state within a predetermined time upon application to the skin to exhibit skin moisturizing and soothing effects through an improved skin absorption rate and a method for manufacturing a mask pack using the same will be.

When the body temperature is 36.5 ℃, the skin is normal at 31 ℃, which is 5 ~ 6 ℃ lower than this. However, if you are exposed to sunlight for a long time, your skin will rise to over 40 ℃. At this time, the capillaries of the skin are enlarged and the pores expand, causing the elasticity to fall.

Recently, the theory of skin aging due to recent skin temperature, such as increasing the collagenase of the dermis layer as well as the high skin temperature, or making rough and dull skin, has been disclosed in the paper, thereby lowering the skin temperature, The interest in cosmetics is increasing.

Recently, a hydrogel mask has been developed and has gained popularity in the mask market by enhancing the skin absorption rate of the active ingredient and the like delivered to the skin and cooling the skin. For example, Korean Patent Laid-Open Publication No. 2014-0061115 relates to a sticky hydrogel cosmetic composition containing 0.1 to 1% by weight of sodium polyacrylate having a degree of sodium substitution of 50% or more as a hydrophilic polymer and having excellent formulation stability, It has been disclosed that the hydrogel having an enriched mucus is formed, whereby the skin is excellent in adhesion when applied to the skin, thereby maximizing the absorption of moisture and components into the skin.

However, controlling the drug delivery to the skin while the hydrogel remains in the gel state requires a relatively long time for the drug to penetrate into the skin, and the drug is delivered only to a limited area where the hydrogel contacts the skin There are disadvantages. To overcome this, it was all about adding a penetration enhancer to the hydrogel or making a hydrogel of a skin-friendly composition.

However, in the gel state, there is a limitation in affinity with the skin, and there is a problem that the cosmetic agent can not have a satisfactory amount and speed to be delivered from the hydrogel to the skin. The affinity between the hydrogel and the skin has a crucial influence on the delivery of the cosmetic agent or drug contained in the hydrogel to the skin. That is, if the affinity is large, the delivery of the cosmetic agent or the drug can be easily and rapidly carried out from the hydrogel to the skin, but if the affinity is small, the delivery is not sufficient and slow. In the case of the hydrogel mask, And it was troublesome to remove it.

Hereinafter, the present invention will be described in detail.

The present invention provides a cosmetic composition which can penetrate an active ingredient directly into the skin without the hassle of peeling off the skin after phase change according to temperature conditions.

To this end, the cosmetic composition of the present invention comprises 0.1 to 3% by weight of tamarind gum; 0.15 to 0.45 wt% catechin; 1 to 10% by weight of polyol and water as the remainder.

The endosperm of Tamarindus india L seed is extracted with hot water, hot water or alkaline aqueous solution or treated with? -Galactosidase, and the main component is polysaccharide. It is stable to organic acid and salt, and does not decompose even when heated, and is excellent in acid resistance and salt resistance. It is also a complex polysaccharide composed of tamarind black glucose, xylose, galactose and the like.

Wherein the content of tamarind black is in the range of 0.1 to 3% by weight. If the content is less than the above range, it is difficult to maintain the gel state even in a refrigerated storage condition, and if it exceeds the above range, it affects the stability in the formulation.

Also, it is preferable to have a molecular weight of 450,000 Da to 750,000 Da, considering the purpose of using tamarind black.

The catechin is added for dehydration of tamarind gum. That is, each molecule is hydrogen bonded to each other through a tamarind black alcohol group, which is agglomerated by dehydration action of catechin to maintain a gel phase at a low temperature (4 ° C.) and a liquid phase phase change at a temperature above 30 ° C.

Preferably, such catechins are included in the total cosmetic composition in an amount of 0.15 to 0.45% by weight. If it is contained in an amount less than 0.15% by weight, it is difficult to change into a gel state at a low temperature, and when it is contained in an amount exceeding 0.45% by weight, it can not be changed into a liquid state upon application of human skin.

At this time, the polyol is used for moisturizing, and it is used for moisturizing, and may be used in the form of a liquid such as glycerin, 1,3-propylene glycol, butylene glycol, dipropylene glycol, glycerin, erythritol, xylitol, maltitol glycerin, sorbitol, polyglycerin, polyethylene glycol, Isoprene glycol, and a combination thereof. Such a polyol is used in an amount of 1 to 10% by weight in the total composition. If the content is less than the above range, it is difficult to secure sufficient moisture resistance. On the other hand, It can be used properly within the above range.

The water is distilled water, preferably deionized distilled water, and is used as the remainder to satisfy 100 wt% of the total weight%.

The cosmetic composition according to the present invention maintains a gel state at 0 to 10 캜 in a refrigerated condition and changes its phase into a liquid state within 10 minutes when it is applied to human skin at room temperature.

Accordingly, it can be stored under refrigeration conditions of 0 to 10 ° C and can be used under normal temperature conditions.

Specifically, the cosmetic composition is poured in a mask mold and stored in a refrigerated condition at 0 to 10 ° C for 20 minutes to 1 hour to obtain a gel mask pack. When applied to the skin at room temperature, Active ingredients can penetrate the skin without hassle. That is, when the thick gel at a temperature lower than the body temperature changes into liquid, it not only calms the skin but also obtains a skin moisturizing effect.

In addition, additives such as water-soluble active ingredients, antiseptics, antioxidants, pigments, dyes, fragrances and the like, which are well known in the art, can be further added if necessary, and the kind and content thereof can be suitably selected by those skilled in the art

The water soluble active ingredient may be selected from the group consisting of vitamin B and its derivatives, arbutin, water soluble vitamin C derivatives including ascorbic acid-2-glucoside, niacinamide, adenosine, N-acetylglucosamine N-acetylglucosamine), epicalocatechin gallate, various water-soluble plant extracts, and the like.
