Description

  The present invention relates to a liquid detergent for textile products.

Two types of cleaning agents for textile products whose clothing is to be cleaned are generally powder cleaning agents and liquid cleaning agents. The demand for liquid detergents has been increasing because there is no concern about undissolved residue and because it can be applied to clothing and the like.
In recent years, there has been a demand for a liquid cleaning agent that can be rinsed with a small amount of water and has a good rinsing property because of increased awareness of environmental burdens. Especially for washing clothes, washing machines with low water consumption, such as drum-type washing machines, are used, and liquid detergents can be rinsed once even under conditions of low water usage. There is a need to promote the objects to be cleaned.

In recent years, some liquid detergents have improved texture improvement effects in addition to excellent detergency and excellent rinsing performance for objects to be cleaned.
For example, a liquid detergent composition containing a nonionic surfactant, an aliphatic amidoalkyl tertiary amine, a hydrotrope, and a protease has been proposed (for example, Patent Document 1). According to the invention of Patent Document 1, the detergency is good, it has an excellent flexibility-imparting effect, and the stability over time is improved.

JP-A-2005-105107

However, according to the conventional technique, although the washed fiber product can be given flexibility, it has a moist feel. Some textiles prefer a dry and dry feel.
Accordingly, the present invention is directed to a liquid cleaning agent for textiles that has good rinsing properties and can give a dry feel to the object to be cleaned without impairing the flexibility of the object to be cleaned.
