Eye-makeup cosmetic composition

Abstract

The present invention relates to a colored cosmetic composition for making up eyes, in particular eyelids. One of the aspects of the present invention is a colored cosmetic composition for making up eyes, in particular to eyelids, comprising: (i) at least one polymer which has a Tg of −30° C. or less; (ii) at least one hydrophilic thickener; (iii) at least one pigment; and (iv) water. The cosmetic composition according to the present invention can provide a good feeling during use and appropriate adhesiveness to fake eyelashes, and is stable over time.

(15) Sensory Evaluation

(16) Each of the compositions according to Examples 1-8 is applied, as an eyeliner, to the edges of eyelids of each of 10 panelists in total. The feeling to use of the compositions according to Examples 1-8 is good.

(17) The adhesiveness of the compositions according to Examples 1-8 to the eyelids is sufficient to provide long term eye-makeup effects, while they can be removed by cleansing oil.

(18) Next, each of the compositions according to Examples 1-8 is applied to a fake eyelash. After drying the applied composition, the fake eyelash is attached to the eyelid of each of 10 panelists in total.

(19) As controls, a commercial adhesive product (Main Ingredient: Acrylic Resin, Control 1) for fake eyelashes comprising 54% by weight of acrylic resin and 46% by weight water is applied to a fake eyelash. After drying the applied composition, the fake eyelash is attached to the other eyelid of each of the 5 panelists. In addition, instead of Control 1, another commercial adhesive product (Main Ingredient: Natural Gum, Control 2) for fake eyelashes comprising natural gum latex is applied to a fake eyelash. After drying the applied composition, the fake eyelash is attached to the other eyelid of each of the 5 panelists.

(20) The removability of the fake eyelash and irritation caused by the fake eyelash are compared for the 10 panelists in total.

(21) The results are that the compositions according to Examples 1-8 show better removability than Control 1, with a comfortable feeling when removing the fake eyelash, and that the compositions according to Examples 1-8 show better removability than Control 2, and are less irritative than Control 2.
