Massage cosmetic composition containing encapsulated pigments

The present invention relates to a massage cosmetic composition containing an encapsulated pigment that gives an optimal skin massage time.

Cosmetics are aimed at preventing aging by cleaning the body and protecting one's skin and hair from ultraviolet rays and drying if they make themselves beautiful and attractive.

Recently, due to the increase of social activities, the self-consciousness to express oneself actively has increased, and the desire to care for and maintain one's own skin by using cosmetics has greatly increased. And thus new formulations are introduced.

Massage cosmetic products are applied by applying a moderate amount to the skin and rolling gently. These products effectively cleanse skin metabolism harmful substances, secretions, externally attached contaminants, makeup residues, and prevent wrinkles by stimulating blood flow by stimulating nerves and blood vessels distributed in the dermis and subcutaneous tissue. Has

The usual massage time is about 10-20 minutes, and if the massage time is too long, it irritates the skin, so the user can feel more convenient when checking the massage time with the naked eye.

Meanwhile, interest in cosmetics that change color in response to external stimuli such as pH change, shear force, light, heat, and the like is increasing.

Accordingly, the inventors have conducted various studies on the composition of the massage. As a result, the inventors have encapsulated the pigment to visually check the optimal massage time, and at this time, use alcohol to dissolve the capsule material to effectively control the destruction of the capsule. While using, it was found that the capsule breaking time can be effectively controlled according to the content of the alcohol to complete the present invention.

An object of the present invention is to provide a massage cosmetic composition that can tell the optimal skin massage time.

In order to achieve the above object, the present invention provides a massage cosmetic composition comprising an encapsulated pigment and an alcohol in a cosmetic composition comprising an aqueous phase and an oil phase.

The composition according to the present invention shows the effect of informing the optimal skin rolling time during the massage through the color expression of the pigment during the skin massage, it can be applied to various massage products.

1 is a photograph showing the color expression after the skin rolling of the cosmetic composition prepared in Example 1.

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

The massage cosmetic composition according to the present invention is an emulsion composition including an aqueous phase and an oil phase, and includes a pigment and an alcohol encapsulated in the emulsion composition.

The massage cosmetic composition releases the pigment present in the capsule as the capsule is broken during the massage of the skin for massage, thereby causing a certain color to be expressed on the skin to end the massage. As a result, it is possible to reduce the skin irritation caused by excessive massage by inhibiting the skin rolling for a longer time than necessary, it is possible to adjust the optimal massage time for the type of massage products.

Destruction of the capsule can be accomplished in a variety of ways, but is carried out with the use of certain materials that can decompose, dissolve or dissociate the material constituting the capsule. In the present invention, by using shellac, mannitol, lecithin and the like as the capsule material, lower alcohol is used as the capsule breaking material.

As the lower alcohol, methanol, ethanol, propanol, isopropanol, butanol and a mixed solvent thereof may be used, and ethanol is used in consideration of skin stability.

The rate of breakdown of the capsule is related to the ratio of the content of the capsule to the pigment and the content of the capsule to the lower alcohol. That is, the encapsulated pigment should mask the original color of the pigment until storage or use in the massage cosmetic composition and prevent the unwanted release of the encapsulated material into the composition during manufacture or for prolonged storage. In addition, in the case of the lower alcohol, the breaking rate of the capsule is controlled according to its content, so in the case of excessive content, the capsule may be destroyed in advance in a long-term storage process.

Preferably, the capsule material is used in a weight ratio of 1: 4 to 4: 1, and the encapsulated pigment: lower alcohol is used in a weight ratio range of 1: 5 to 1:10, and then the capsule is within 10 to 40 minutes. Destruction occurs.

In connection with such a content limitation, if the content of the capsule material and the content of the lower alcohol is less than the above range, the capsule breakdown occurs during storage of the massage cosmetic composition, so that the pigment is released before use or difficult to control the rolling time. If the content of the lower alcohol is less than the above range, there is a possibility that skin irritation may occur due to excessive rolling due to less expression by the pigment after capsule breakage.

The pigment encapsulated in the present invention is used in 0.1 to 5% by weight, preferably 0.3 to 0.8% by weight in the total composition, the lower alcohol is in the range of 1 to 5% by weight, preferably 2 to 5% by weight. use. If the content of the encapsulated pigment is less than the above range, there is a problem that the pigment is not expressed during the massage, on the contrary, if the amount exceeds the above range, the color is expressed even though the massage time is short, so that the proper massage time cannot be adjusted. . In addition, when the content of the lower alcohol is less than the above range, the pigment expression time is delayed, and if it exceeds the above range, the pigment expression time is too short, there is a disadvantage that can not adjust the appropriate massage time.
