Description

  The present invention relates to a cleaning composition.

  Conventionally, wool and dry mark garment detergents, so-called light detergents, have been used in knitted products, primarily wool sweaters. However, in recent years, washing with this light detergent can reduce shape loss during washing, so not only wool sweaters but also fashionable clothes such as synthetic fiber and cotton cut-and-sew and pants, as well as underwear such as bras and shorts. It is becoming used.

  On the other hand, the light detergent requires touch and flexibility when the laundry is dried and worn. Cationic surfactants and amino-modified silicone compounds are generally used as a base for expressing the touch and flexibility. With respect to the performance of these bases, amino-modified silicone compounds are highly effective for wool materials, and cationic surfactants are highly effective for synthetic fibers and cotton materials.

  Considering the actual usage of light detergents, it is conceivable to use a cationic surfactant and an amino-modified silicone compound in combination to develop the feel and flexibility of each material of wool, synthetic fiber and cotton. However, when washing with these two agents in combination, the softness of the synthetic fiber and cotton is improved compared with the detergent containing the amino-modified silicone compound, but the wool has a hard finish, and the user's request is sufficient. Can't be satisfied.

Further, it has been proposed to use a cationic surfactant in combination with another modified silicone. For example, Patent Document 1 discloses a cleaning composition containing a nonionic surfactant, a quaternary ammonium salt type cationic surfactant, and a carboxyl-modified polysiloxane. Further, it has been proposed to use a cationic surfactant in combination with another modified silicone. For example, Patent Document 1 discloses a cleaning composition containing a nonionic surfactant, a quaternary ammonium salt type cationic surfactant, and a carboxyl-modified polysiloxane. Patent Document 2 discloses an aqueous emulsion containing an anionic group-containing organopolysiloxane and a cationic surfactant and applicable to fibers, but does not exhibit sufficient performance.
