Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition, and more particularly to a detergent composition having a good feeling in use, a high detergency and a low irritation, which does not damage the skin or hair. It relates to a composition.

[0002]

2. Description of the Related Art Phosphate ester-based surfactants, which are a type of anionic surfactant, are extremely mild surfactants that have low irritation to skin and hair. It has been accepted and conventionally straight chain phosphates have been utilized as a component of detergent compositions.

However, although this phosphate has sufficient detergency in the case of cleaning weak dirt,
It was insufficient for cleaning stains that require high cleaning power and are hard to remove. In particular, in recent years, the development of makeup products has made it difficult to remove makeup, and the development of hair cosmetics has made it more difficult to remove polymers and the like contained in setting agents and the like. A low detergent composition was desired.

[0004]

Under the circumstances, as a result of intensive studies by the present inventors, the use of a specific β-branched phosphate-based surfactant has high detergency and, in addition, the skin. It was found that a detergent composition with low irritation can be obtained, and the present invention was completed.

That is, the present invention provides the following general formula (1):
