In the technique of Patent Document 1, although it may have a rich feeling and a high repair effect, depending on the case of containing other ingredients, there is a problem that the stability over time such as emulsion stability may not be excellent. .
In the technique of Patent Document 2, although it may give a light moist feeling, a dry feeling and a manageable feeling to the hair after drying, the higher alcohol increases the viscosity, the smoothness at the time of application is not excellent, and the usability is lacking. There was a problem that there is
In the technique of Patent Document 3, although it may be excellent in preventing peeling of the cuticle of the hair, it may not be excellent in compatibility with wet hair, and the place and method of use may be limited. there were. In addition, when the composition does not have excellent compatibility with wet hair, the applied composition becomes watery, so that it cannot be properly applied to the hair.
In the technique of Patent Document 4, although the gloss and manageability of the hair may be excellent, there is a problem that the smoothness at the time of application and the finger combability of the finish may not be excellent.
In the technique of Patent Document 5, although there are cases where the touch and finger combing are good even after volatilization, there is a problem that there are cases where the stability over time such as high temperature stability is not excellent.
In the technique of Patent Document 6, although it may be easy to adapt to the hair, there is a problem that the smoothness at the time of application, the finger combability of the finish, and the absence of stickiness may not be excellent.
Therefore, compared to conventional techniques, the hair is excellent in smoothness during application, smoothness of the finish, and non-stickiness, and in addition, it is an O/W type hair that has excellent compatibility with wet hair and excellent stability over time. It has been difficult to embody oil-in-water compositions for industrial use.

There has been a demand for the development of an oil-in-water composition for hair that has excellent smoothness during application, finger combing in the finish, non-stickiness, good compatibility with wet hair, and excellent stability over time.
In view of the above-mentioned circumstances, the present inventors have made intensive studies and found that the oil-in-water composition for hair contains a cationic surfactant, a saturated higher alcohol, and a specific methylpolysiloxane as an oil to improve the finish. I got the knowledge that the street is greatly improved.
However, this alone was insufficient for the smoothness when applied to the hair, and as a result of further investigation, it was found that the inclusion of a specific amount of phospholipid greatly improves the smoothness when applied. It is considered that this is because the phospholipid unexpectedly softens the α-gel that may exist near the emulsified interface of the oil-in-water composition for hair.
As a result of further intensive studies, it was found that when the polyhydric alcohol having 3 to 6 carbon atoms is further contained and the content ratio by mass of the polyhydric alcohol having 3 to 6 carbon atoms and the phospholipid is specified, it is compatible with wet hair. The present inventors have found that an oil-in-water composition for hair that is excellent in smoothness during application, smoothness of the finish, non-stickiness, and stability over time has been achieved, leading to the completion of the present invention.

That is, the present invention provides the following [1] to [6].
