JP6842402B2 - How to remove sweat and / or sebum - Google Patents

Description

The present invention relates to a method for removing sweat and / or sebum.

Conventionally, as a cleaning sheet for removing stains adhering to the skin, particularly the face, an oily substance absorbing dry sheet and an aqueous composition impregnated wet sheet are known.
As an example of a dry sheet, in addition to the commonly used grease-removing paper, it has an excellent oil-wiping effect and wipes off the oil on the skin surface before makeup and on the skin after makeup to prevent makeup paste and skin shine after makeup. For the purpose of this, a cosmetic oil-removing sheet made of a non-woven fabric having a specific fiber density and texture made of lipophilic fibers has been proposed (see Patent Document 1). As an example of a wet sheet, a sheet obtained by impregnating a sheet base material having a specific thickness and bending hardness with an aqueous medium for the purpose of effectively removing excess sebum and dirt that have emerged on the skin surface. Cosmetic cosmetics have been proposed (see Patent Document 2). In addition, the water-based cleaning agent composition is contained in a water-flow entangled non-woven fabric made of cellulose fibers and synthetic fibers for the purpose of exhibiting excellent retention ability of the water-based cleaning agent and exerting high cleaning power against makeup stains and skin oil stains. A skin cleansing sheet has been proposed (see Patent Document 3).

Dry sheets such as grease-removing paper and cosmetic oil-removing sheets described in Patent Document 1 can adsorb sebum on the sheets and remove the sebum that has emerged from the skin, but cause stickiness. Since the sweat cannot be adsorbed on the sheet, the sweat remains on the skin even after use, so that the stickiness could not be removed and the feeling that the dirt could be removed was not obtained. In addition, the dry sheet collapses due to sebum, and the collapsed makeup cosmetics mixed with sebum cannot be entwined from the skin and remain on the skin as it is, so even if you remake after use, the makeup will be clean. There was a problem that it could not be finished.
Further, since the wet sheets of Patent Documents 2 and 3 are intended to clean the skin by removing sweat, sebum and make-up cosmetics, they are placed on the skin to which the make-up cosmetics are applied. It is not intended to remove makeup cosmetics that are not removed from the skin, but only to remove the broken makeup cosmetics mixed with sweat and sebum on the skin, and even makeup cosmetics that you do not want to remove. It was supposed to be removed. Therefore, even if you want to get rid of sweat and sebum, you have to reapply makeup cosmetics after wiping it off, so it takes time to reapply makeup and it is difficult for women who make up on a daily basis to use it. There was a problem.
Therefore, for women who make up on a daily basis, without removing the make-up cosmetics, only the stickiness and sebum of the skin and the crumbled make-up cosmetics mixed with the sebum are removed, and the user is advised. There has been a long-awaited way to provide a clean, clean skin feel.

In view of these issues, without removing the make-up cosmetics, only the stickiness and sebum of the skin and the crumbled make-up cosmetics mixed with the sebum are removed to give the user a clean and clean skin feel. As a result of searching for the method to be provided, the present inventor has specified a specific amount of nonionic surfactant, divalent and / or trivalent alcohol in a non-woven fabric in which hydrophobic fibers and hydrophilic fibers are combined in a specific ratio. By wiping from the top of the skin to which the make-up cosmetics have been applied using a sheet containing the water-based composition contained in the proportion, sweat on the skin and / Alternatively, it has been found that sebum and crumbled make-up cosmetics mixed with sebum can be effectively removed.

In the present invention, by wiping the sheet obtained as described above over the skin to which a make-up cosmetic such as foundation is applied, sweat and / or sebum and crumbled make-up mixed with sebum The cosmetics can be effectively removed.
It should be noted that the act of wiping is to wipe the skin by pressing it lightly from the top of the skin in the form of a grease-removing paper, which is completely different from the act of wiping the skin.
Although the mechanism by which the effects of the present invention are exhibited is not clear, the mechanism is that the hydrophobic fibers in the sheet adsorb and remove the sebum that has emerged on the skin and the crumbled make-up cosmetics mixed with the sebum. , The water-based composition is released from the non-woven fabric by wiping the sheet against the skin, and at the same time, the mechanism of dissolving and removing only the sweat that causes stickiness is manifested, so that sweat and / or sebum and sebum and It is presumed that the crumbled make-up cosmetics mixed with sebum are effectively removed from the skin, producing an effect of refreshing the skin.
Taking advantage of this property, the skin is gently wiped from the top of the make-up woman's skin with a sheet impregnated with a specific aqueous composition on a non-woven fabric with a specific ratio of hydrophilic fibers and hydrophobic fibers. It is truly surprising that the make-up cosmetics attached to the skin are not removed, and only the sweat and / or the sebum and the crumbled make-up cosmetics mixed with the sebum are effectively removed from the skin.

The evaluation in the examples was performed according to the method shown below.
(1) Thickness of non-woven fabric:
The thickness of each sheet is based on the "thickness" test method A of the general short fiber non-woven fabric test method (JIS L 1913), using a constant pressure thickness measuring instrument (S-10908 type, manufactured by Teclock Co., Ltd.). The thickness at any 5 points was measured and used as the average value.

(2) Removal of sebum:
20 μL of model sebum (cottonseed oil colored with oil-soluble pigment (Oil Orange SS, manufactured by Tokyo Kasei Kogyo Co., Ltd.)) was dropped onto a PS plate (balance dish model number BD-3, manufactured by AS ONE Corporation), and the size was 2 cm x 2 cm. Spread evenly over the area. A sheet obtained by impregnating a non-woven fabric previously cut into 8 cm × 8 cm with each composition in a specified amount with a polydropper in half was placed on the model sebum and pressed for 5 seconds with a load of 500 g. Then, the sheet was removed, and the amount of remaining sebum was visually evaluated according to the following criteria.
1: Sebum is not reduced at all.
2: Sebum is slightly reduced.
3: The sebum is reduced, but the PS plate is not exposed.
4: A small amount of sebum remains, and a part of the PS plate is exposed.
5: Almost no sebum remains, and the entire PS plate is exposed.

(3) Makeup cosmetics are not good:
Take 5 mg of liquid foundation (Primavista Makeup Glue Liquid Foundation Ocher No. 05, manufactured by Kao Corporation) (hereinafter referred to as FD) on a PS plate (balance dish model number BD-3, manufactured by AS ONE) and make it within a range of 2 cm x 2 cm. Spread evenly. A sheet obtained by impregnating a non-woven fabric previously cut into 8 cm × 8 cm with each composition in a specified amount with a polydropper in half was placed on a liquid foundation, and a load of 500 g was applied to hold the non-woven fabric for 5 seconds.
