Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a hair composition. More specifically, the present invention relates to a hair composition that satisfies both ease of removal from a bottle and usability.

[0002]

2. Description of the Related Art Hair compositions having a so-called rinsing effect of imparting softness and gloss to hair and improving combability are commercially available under the names of hair rinse, hair treatment, hair conditioner and the like.

[0003]

SUMMARY OF THE INVENTION These hair compositions having a rinsing effect are intended to be used in bottle containers when pursuing usability such as ease of spreading, spreading, body, and richness when applying the hair. There is a tendency for the liquid to come out from the container.

[0004] Therefore, bottled hair compositions have been provided by adjusting the molar ratio of the composition components and devising the squeezing properties of the container.

[0005] However, in each case, the ease with which the liquid is discharged from the bottle is not sufficient, and a composition which sufficiently satisfies both the usability of the composition and the ease with which the composition is discharged from the bottle has not been obtained.

[0006] The present inventor has made an object of balancing the good usability of the composition and the ease of taking out the composition from a bottle from the viewpoint of rheology. As a result of intensive studies for solving this problem, they have found that the balance between the two is improved in a certain region of the rheological properties of the composition, and completed the present invention.

[0007]

The present invention is as follows.

(A) a fatty acid amidopropylamine derivative or a quaternary ammonium salt, and (B) a carbon atom having 1 carbon atom
And a higher alcohol having a long-chain alkyl of 4 to 22. In the rheological properties, when the shear rate when the shear rate is increased is 10 (1 / S), the shear stress is 20 (P
a) The composition for hair, wherein the shear stress is 80 (Pa) or more and 100 or less when the shear rate is 500 (1 / S) or more and 60 (Pa) or less.

The above-mentioned (B) is a mixture of two or more higher alcohols, and the higher alcohol having a long-chain alkyl having 14 to 19 carbon atoms by mass ratio: 20 carbon atoms.
Higher alcohol having a long-chain alkyl of 22 to 22 = 5.
The aforementioned composition for hair, which is 5: 1 to 1.5: 1.

[0010] (C) The above hair composition further containing 3 to 20% by mass of a humectant.

The hair composition as described above, wherein the hair composition is a rinse that requires rinsing.

A hair composition in a bottle, characterized in that the hair composition is filled in a bottle.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below.

In the present invention, the rheological properties are values measured using a cone plate type viscometer at a cone size of 6 cm, a cone angle of 1 degree, and a measurement temperature of 30 ° C.

When the rheological properties were measured as described above, in the composition of the present invention, when the shear rate when the shear rate was increased was 10 (1 / S), the shear stress was 20 (P).
a) not less than 60 (Pa) and a shear rate of 5
At the time of 00 (1 / S), the shear stress is 80 (Pa) or more and 10
0 (Pa) or less.

When the shear rate is 10 (1 / S) and the shear stress is 60 (Pa) or less, the liquid can be easily discharged from the container, but there is no body or rich feeling during coating.
In addition, when the shear rate is 500 (1 / S) and the shear stress is larger than 100 (Pa), it is difficult to discharge the liquid from the container. Preferably it is about 90.

The above-mentioned rheological properties include, for example, (A)
A gel-based composition comprising a fatty acid amidopropylamine derivative or a quaternary ammonium salt represented by the following general formula or the following general formula, and (B) a higher alcohol having a linear alkyl group having 14 to 22 carbon atoms. The content of (A) is 0.1 to 5% by mass based on the total amount of the composition.
This is achieved by a hair composition wherein the molar ratio (B) / (A) of the content of (B) to the content of (A) is in the range of 3 to 15.
