Description

The present invention relates to a dryness enhancer and a detergent composition.

Conventionally, cleansing compositions such as hand soaps and body soaps are required to impart a dry feel to the skin after being towel-dried. As a cleansing composition capable of imparting dry feeling to the skin after towel-drying, for example, a cleansing composition containing dimethyldiallylammonium chloride polymer, sugar alcohol, silica, etc. has been proposed (see, for example, patent References 1-3).

In addition, since the cleaning composition is used for the purpose of keeping the site to be cleaned clean, it is also required that the use of the cleaning composition gives a feeling of cleanliness. . Among the various properties of detergent compositions, the scent imparted to the detergent composition contributes to creating a feeling of cleanliness, and the highly palatable scent is also an important quality of the detergent composition. It has become. Therefore, detergent compositions containing various fragrance compositions have been proposed (see, for example, Patent Documents 4 to 6).

Therefore, in a cleansing agent composition capable of imparting dry feeling to towel-dried skin, it is possible to make the towel-dried skin feel more dry and impart a clean feeling fragrance. It is strongly demanded to provide a dry feeling enhancer capable of achieving a smooth feeling, and a detergent composition containing the dry feeling enhancer.
