Description

  The present invention relates to a fiber treatment composition. Specifically, the present invention relates to a fiber treatment agent composition that can exhibit antiseptic properties even without adding a large amount of preservatives.

In recent years, commercial forms of commercially available fiber treatment agents (softening agents) are mainly plastic bottles and refillable bag-like containers. In the latter case, since the contents of the bag-like container can be repeatedly filled into a plastic bottle and used, there is an advantage that the amount of plastic can be greatly reduced (reduction of waste) and is inexpensive compared to a plastic bottle.
However, when the contents of a refillable bag-like container are repeatedly filled into a plastic bottle and used, the color tone of the newly filled fiber treatment agent is affected by the effects of environmentally resident bacteria mixed in the bag-like container and propagated. There is a problem that it becomes easy to change.
As a means for solving this problem, a technique of blending a preservative containing antiseptic and antibacterial components is known (Patent Document 1). Antiseptic and antibacterial components are also used to impart long-term stability to fiber treatment agents (Patent Document 2).
Moreover, in the fiber processing agent, the fragrance | flavor component is mix | blended for various purposes (patent documents 3-5).

  Some cationic surfactants used as a base for fiber treatment agents have an antiseptic action. A fiber treatment agent containing a small amount of a cationic surfactant requires a large amount of preservatives in order to suppress miscellaneous bacteria propagation and component deterioration due to miscellaneous bacteria propagation. However, since preservatives are generally expensive, mass blending is economically undesirable. In addition, a large amount of preservative is not preferable from the viewpoint of safety.

  As a result of earnestly examining the above problems, the present inventor has used a perfume composition containing a specific amount of a perfume component in a specific amount in a fiber treatment agent containing a small amount of a cationic surfactant. It was found that even if it is not blended, it exhibits antiseptic properties and can maintain a stable color tone. The present invention has been made based on this finding.
