WO2015163565A1 - Cosmetic composition that specifically reacts to soap - Google Patents

Abstract

The present invention relates to a cosmetic composition including an aqueous phase and an oil phase and, more particularly, to a cosmetic composition including an aqueous phase and an oil phase characterized in that the aqueous phase includes a water-soluble polymer, a water-repellent powder and purified water, and the oil phase includes oil, a hydrophilic emulsifier having an HLB number of 8 to 18 and a lipophilic emulsifier having an HLB number of 2 to 6. In the cosmetic composition of the present invention, a soap-sensing layer is formed by dispersing the water-repellent powder in the aqueous phase and by simultaneously using the hydrophilic emulsifier having an HLB number of 8 to 18 and the lipophilic emulsifier having an HLB number of 2 to 6. Since the soap sensor reacts with a saponification group in soap, the cosmetic composition of the present invention has an advantage over conventional cosmetic compositions of enabling convenient washing even through washing only once.

Description

Cosmetic composition that reacts specifically to soap

The present invention relates to a cosmetic composition comprising a soap sensor, and more particularly, to a cosmetic composition in which cleaning is simplified by including a soap sensor.

Hyundai is a society in which appearances are highly competitive. Accordingly, there is a growing interest in making appearances and expressing personality with makeup. Makeup applies cosmetics to the face to cover flaws, emphasizes its merits, expresses its individual beauty, and protects the skin from external stimuli such as ultraviolet rays. There are various kinds of makeup cosmetics such as make-up base, foundation, twowen cake, BB cream, CC cream, sun cream, eye shadow, lipstick, mascara and eyeliner.

On the other hand, in recent years, the trend of 'during', it is emerging as an important element than to make up. In addition, recently released makeup products are manufactured to have excellent skin adhesion and color repellency and water repellency for excellent skin expression, requiring more meticulous cleansing.

In general, users who make up use a cleansing cream or oil as a primary cleansing to remove the makeup, and then use a detergent such as soap or a cleansing foam as a second cleansing to double face wash. In addition, the color cosmetics are not cleansing well, and may be further subjected to cleansing using each remover.

As described above, the various steps of cleansing take away moisture and oil from the skin and cause irritation of the skin, thus causing trouble on the skin. In order to solve such a problem, natural soaps containing various natural substances as active ingredients, cleansing tools, brushes, vibrators and the like of various formulations have been developed.

However, cleansing still takes place in several stages. Accordingly, there is a need for a solution that satisfies both makeup and cleansing at the same time.

An object of the present invention is to provide a cosmetic composition which can be easily washed by dispersing a water repellent powder in an aqueous phase and simultaneously applying a hydrophilic emulsifier and a lipophilic emulsifier.

In order to achieve the above object, the present invention provides a cosmetic composition consisting of an aqueous phase and an oil phase, specifically in the cosmetic composition consisting of an aqueous phase and an oil phase, the aqueous phase includes a water-soluble polymer, a water-repellent powder and purified water, Silver, the oil composition, the hydrophilic emulsifier whose HLB numbers are 8-18, and the lipophilic emulsifier which HLB numbers are 2-6 are provided, The cosmetic composition characterized by the above-mentioned.
