Description

detergent

The present invention relates to a cleaning agent.

Conventionally, in skin cleansing agents, an anionic surfactant such as an alkyl sulfate or a sulfonate or a higher fatty acid salt is widely used as a main component due to the characteristics of high bubble properties. However, although these anionic surfactants have a refreshing feeling after cleaning, there are problems in that they are tight or dry. A method of providing a skin moisturizing method which is applied to a skin without blistering a detergent having a high concentration of a polyol, and which is rinsing, is provided as a method of reducing the moisturizing feeling after cleansing. Document 1). However, in the skin cleansing agent, the foaming detergent is usually applied to the face after foaming, and is cleaned by massage. Therefore, the original method of application without direct application of the foam is not performed, and the full use cannot be performed. There are many cases of effects.

On the other hand, the "bubble type cleaning material" which is used by filling the cleaning material composition into a foaming container and ejecting it in a bubble shape can be cleaned with a fine texture of the foam while being less rubbed against the skin, and It is widely used because it is easier to foam the detergent by hand. The foam type cleaning material is also a user who directly applies the foam sprayed from the foaming container to the skin. Therefore, if the polyol is blended in the cleaning material, it is expected to obtain a moist moisturizing feeling after cleaning.

However, when the polyol is blended at a high concentration in the cleaning material, the viscosity of the composition rises, and when it is used for a foamed container, the discharge property of the bubble is deteriorated. In particular, there is a problem that the texture of the bubble at a low temperature is coarse and the shape retention property is deteriorated (Patent Document 2 and Patent Document 3). Therefore, it is impossible to formulate a polyol at a high concentration in the cleaning composition filled into the foaming container.

The polyol or the alcohol (1) can reduce the liquid viscosity of the cleaning material and the viscosity of the liquid at a low temperature by combining with the polyol of the component (C), and obtain a fine texture of fine foam from the foamed container.

In the polyol-based polyol of the component (C), a higher moisturizing effect can be obtained, but if it is formulated in a cleaning material, the viscosity becomes high, and the texture of the bubble which is ejected at a low temperature becomes thick. Therefore, it is difficult to prepare the cleaning material separately and in a large amount.
