Description

[0001] POWDER TYPE WET TISSUE [0002]

The present invention relates to a wet tissue capable of imparting a feeling of being smooth and / or smooth.

A wet tissue is a kind of tissue paper. It refers to a damp paper tissue that contains water during the manufacturing process. These wipes are mainly used for removing pollutants, and they are mainly used for cleaning hands and face, removing contaminants present in daily necessities, and treating children's defecation.

When the diaper is filled or the underwear is applied after using the wet tissue for the defecation treatment of the infant, the moisture transferred from the wet tissue may exist on the skin in a state of not ventilating, and the skin may become dull. Therefore, when defecation treatment is performed with a wet tissue, it is troublesome to apply powder that can impart smoothness or smoothness so that the skin does not get stuck.

In order to solve such a problem, a technique has been proposed in which a talc ingredient is added to a wet tissue to perform a bowel treatment and a powder effect can be seen. However, as a result of research that asbestos, one of the carcinogens, can be detected in talc, the use of a wet tissue containing a talc component in a human, especially an infant, can cause serious health problems.
