Description

The present invention relates to a cleansing cosmetic, and more particularly to a cleansing cosmetic that has a warming effect and is excellent in cleansing power.

Cleansing cosmetics are designed using surfactants and oils to remove makeup adhered to the skin such as makeup cosmetics, dust, and sebum. In recent years, many waterproof makeup cosmetics that are resistant to tears and sweat are used, and cleansing cosmetics are required to have a stronger cleansing power than before.

On the other hand, when removing makeup cosmetics using cleansing cosmetics, cleansing that also has a facial massage effect is performed by applying the cleansing cosmetics to the makeup cosmetics with fingertips etc. Proposals related to the use of cosmetics are also widely made.

As the use of cleansing cosmetics that also serve as a facial massage effect spreads, many cleansing cosmetics that are suitable for cleansing acts that also serve as massages have been proposed. For example, as cleansing cosmetics suitable for massage, Cleansing cosmetics such as emulsification type and aqueous gel type have been proposed.

Comparing the characteristics of the emulsifying type and the aqueous gel type cleansing cosmetics, the emulsifying type uses an oil agent compared to the aqueous gel type and has an excellent cleansing power, whereas the aqueous gel type is multivalent. It is possible to give a warm feeling effect by using a large amount of alcohol, and there is a feature that a high massage effect and cleansing power can be imparted (for example, Patent Document 1).

However, the cleansing power of the water-based gel type cleansing cosmetic does not reach that of the emulsified type, and it is technically difficult to give the emulsion type cleansing cosmetic a sufficient massage effect as the water-based gel type. There has been no proposal of cleansing cosmetics that have both advantages at a level that satisfies consumers.

From such a background, there is a need for cleansing cosmetics that have both an emulsifying type and aqueous gel type characteristics, have a massage effect, and are excellent in cleansing power.

Japanese Patent No. 585750

This invention is made | formed in view of the said situation, The objective is to provide the cleansing cosmetics which are excellent in cleansing power, while having a warm feeling effect.

As a result of intensive studies to achieve the object of the present invention, the present inventors have increased the amount of oil agent in cleansing cosmetics by combining a large amount of glycerin or polyethylene glycol with a specific surfactant and a specific polymer. It was found that it can be included, and the present invention was completed.

In addition, the compounding quantity in all the following examples and comparative examples is the mass%.

[Warm feeling effect (rising temperature)]
The evaluation of the warming effect (rising temperature) for the present invention is based on the change in the temperature of the face before using the cleansing cosmetic and the change in the temperature of the face after massaging for 5 minutes using the cleansing cosmetic (radiation temperature). The measurement was performed using a total of IT-545S). When the temperature of the face surface rises above 1.5 ° C, it is assumed that there is a warming effect (rising temperature), and when the temperature rise is below 1.5 ° C, the warming effect (rising temperature) is insufficient. Or not.

In the present invention, the cleansing cosmetics of the examples and comparative examples are used by 10 professional panels, and the thermal effect (sustainability), cleansing power, and usability (ease of massage) are evaluated by sensory evaluation. went.
