DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a detergent composition containing an anionic surfactant.

[0002]

2. Description of the Related Art Anionic surfactants are widely used as components of detergents generally used in the industrial field and households. This anionic surfactant has various structures,
In recent years, it has been desired to have a good water solubility, good detergency and good foaming, a mild texture on the skin and hair after use, and an effect with a small amount. In response to these demands, a multi-chain poly-hydrophilic group type surfactant having a plurality of lipophilic groups and a plurality of hydrophilic groups in a molecule as having good water solubility and having a surfactant even at a low concentration ( Gemini type surfactants) are known (Iksan, Yuki Kagaku, 44, 54).
3 (1995). However, since this type of surfactant links a plurality of lipophilic groups and a plurality of hydrophilic groups, its production method is complicated, and it cannot be said that it is cost-effective. On the other hand, as a mild anionic surfactant for the skin and hair, there is a combination of a conventional general-purpose anionic surfactant and a polyvalent cation. As the polyvalent cation,
Methyl viologen, 1,1 ′-(1, ω-alkanediyl) bispyridine, propylene diamine, 2-hydroxypropylene diamine, and the like are used (Moshii, Surface, 30, 240 (1992), JP-A-9-34).
83). However, these polyvalent cations have the disadvantage that they lower the critical micelle concentration (cmc) of the surfactant, but have a significant effect on solubility.

[0003]

The object of the present invention is to provide a detergent composition which is excellent in water solubility even under low temperatures, has good foaming and foaming properties, and has a good texture and mildness to skin and hair. The subject.
