Description

  The present invention relates to a non-aqueous cleaning composition using a non-aqueous solvent as a cleaning medium, a non-aqueous cleaning agent using the same, and a dry cleaning method using the same.

  In dry cleaning, so-called petroleum-based, chlorine-based, and fluorine-based organic solvents are used, and cleaning agents suitable for the respective organic solvents are prepared. The non-aqueous detergent composition contains various surfactants, and among them, the cationic surfactant provides a texture, flexibility and antistatic properties to the washed clothes.

  Generally, the non-aqueous detergent used for dry cleaning is a mixture of 0.1 to 5% by mass of this non-aqueous detergent composition with respect to a non-aqueous solvent that is a washing medium.

  However, in recent years, the needs of users of dry cleaning services have been diversified. Furthermore, in addition to general users, there are an increasing number of users such as hospitals, nursing homes, day nurseries and the like. As a result, a greater number of users have come to seek further improvements in the texture and feel of dry-cleaned clothing, and prefer to use natural ingredients.

  Therefore, as a result of intensive studies in view of the above matters, the present inventors have found that a non-aqueous cleaning composition containing camellia oil in addition to a cationic surfactant has further added flexibility and touch (moistness) to the washed clothes. It was found to give a feeling.

According to the present invention, it is possible to provide a non-aqueous cleaning composition containing a quaternary ammonium salt cationic surfactant and camellia oil.
In addition, when the fabric is washed with a non-aqueous detergent in which the non-aqueous detergent composition of the present invention is blended in a non-aqueous solvent, the bending resistance is not blended with the non-aqueous detergent composition of the present invention. It is possible to provide a non-aqueous detergent composition that is 95% or less of the bending resistance when a cloth is washed with the non-aqueous solvent.

  The content of the camellia oil with respect to the total amount of the non-aqueous detergent composition is not particularly limited and can be appropriately selected. When the content is less than 0.1% by mass, the flexibility and feel (moist feeling) given to the clothes after washing is lowered. On the other hand, when the content exceeds 10% by mass, the antistatic property and the like of other components that are relatively decreased in content is decreased, and therefore, preferably 0.1% by mass or more and 10% by mass or less, More preferably, it is 0.1 mass% or more and 7 mass% or less.
