Description
TECHNICAL FIELD
[0001] The present invention relates to a hair cosmetic composition
which has excellent effects for repairing or preventing hair damage
caused by coloring or blow drying, has good feeling upon use and is
effective for improving the luster and shine of the hair.
BACKGROUND ART
[0002] With recent popularization of hair coloring, damage after
treatment with a coloring system (one-part type or two-part type)
such as dryness or difficulty in styling of the hair has drawn
attentions. The permanent waved hair also suffers such damage. The
hair damage due to coloring or permanent waving treatment is said
to occur because pores appear inside of the hair by chemical
factors of the hair dye or permanent waving agent applied to the
hair.
[0003] The hair loses its luster and moisture even by blow drying
after shampooing. Such damage is found to occur because the inside
of the hair becomes porous by the heat from a drier (Fragrance
Journal, No. 6, 11(2000)).
[0004] For improving the touch feel of the shampooed hair, a hair
cosmetic composition such as hair rinse, hair conditioner or hair
treatment has been used. This hair cosmetic composition contains a
cationic surfactant. Since single use of it is not sufficient for
improving touch feel such as flexibility, a higher alcohol has been
used in combination. This higher alcohol imparts the hair with
flexibility and oily feel, thereby attaining an improvement in the
touch feel. Owing to its high melting point, however, addition of
it makes preparation of a hair cosmetic composition cumbersome and
moreover, the hair cosmetic composition thus prepared involves a
problem in stability (Japanese Patent Application Laid-Open (Kokai)
No. 2000-72628, etc.).
[0005] Various hair cosmetic compositions having an
organopolysiloxane oxyalkylene copolymer, acrylic resin or the like
incorporated therein in order to improve optical properties of the
hair such as luster have been proposed (for example, Japanese
Patent Application Laid-Open (Kokal) No. Sho 55-33745). In these
cosmetic compositions, improvement of optical properties is
attained by the action of such a component on cuticles existing on
the hair surface or in the vicinity thereof and its effect is only
temporary and is not sufficient. In addition, a hair cosmetic
composition for imparting the hair with luster by using a cationic
surfactant in combination with a polyhydric alcohol, hydroxypropyl
cellulose or the like is also proposed (Japanese Patent Publication
No. 2998027), but it involves a problem in the touch feel upon
application to the hair.
DISCLOSURE OF THE INVENTION
[0006] An object of the present invention is to provide a hair
cosmetic composition which is capable of repairing pores formed
inside of the colored, permanent waved or blow dried hair or
preventing formation of them; is capable of imparting the hair with
flexibility and oil feel, and in turn, smooth touch and improving
optical properties of the hair such as luster, thus having
excellent hair conditioning effects; is excellent in feeling upon
use when applied to the hair; and has good stability.
[0007] The present inventors have found that a hair cosmetic
composition capable of satisfying the above-described requirements
is available by using an organic acid, a specific organic solvent,
a cationic surfactant and a higher alcohol in combination and
adjusting its pH within a specific range.
[0008] In one aspect of the present invention, there is thus
provided a hair cosmetic composition which comprises the following
components (A) to (D):
[0009] (A): an organic acid,
[0010] (B): an organic solvent selected from aromatic alcohols,
polyols and carbonates,
[0011] (C): a cationic surfactant, and
[0012] (D): a higher alcohol, and water and has a pH ranging from 2
to 6.
[0013] In another aspect of the present invention, there is also
provided a method for repairing pores formed inside of the colored,
permanent waved or blow dried hair; or a method for preventing
formation of pores inside of the colored, permanent waved or blow
dried hair, each method being characterized by the application of
the above-mentioned hair cosmetic composition to hair.
BEST MODE FOR CARRYING OUT THE INVENTION
[0014] Examples of the organic acid to be used as the component (A)
include alkylsulfuric acids, alkylphosphoric acids, monocarboxylic
acids, dicarboxylic acids, hydroxycarboxylic acids and

rinse, hair conditioner or hair treatment.
EXAMPLES
Example 1
[0030] The hair conditioners shown in Table 1 were prepared. The
disappearance ratio of pores inside of the hair was measured; and
smoothness of the hair upon rinsing, and smoothness of the hair,
improvement in luster, dryness and styling ease of the hair after
drying were evaluated. The results are shown in Table 1.
[0031] (i) Disappearance Ratio of Pores Inside of the Hair
[0032] A hair bundle (0.5 g) damaged by coloring was washed with 1
g of a plain shampoo (prepared using sodium polyoxyethylene (2.5)
laurylether sulfate and diethanolamide). After water was drained
off roughly, 1 g of a hair conditioner was applied to the hair
bundle. The resulting hair bundle was allowed to stand for 1
minute, followed by further application of 4 g of the hair
conditioner. It was then allowed to stand at 35 C. for 15 minutes.
The hair bundle was rinsed with running water for 15 seconds, towel
dried and hot-air dried by a drier for 1 minute (this hair
treatment corresponds to successive use of the hair conditioner for
1 week). After this hair treatment was repeated 4 times in total,
the disappearance ratio of pores inside of the hair was
determined.
[0033] Measurement of Pores
[0034] The hair was exposed to a light irradiated obliquely (angle:
15 to 60 degrees between the hair axis and light irradiation axis
from a light source) from the hair root direction and observed from
a direction on the same plane with the hair axis and light
irradiation axis and at the same time, vertical to the hair axis by
using a simple measuring microscope ("WIDE STAND MICRO", product of
PEAK, .times.10). This method makes it possible to remove a
specular reflection light on the surface of the hair, which
otherwise disturbs observation, thereby permitting observation of
only the porous structure at the medulla as white streaks at the
center portion of the hair when the hair has pores formed therein
("Fragrance Journal, No.6, 11(2000)"). Before treatment, the whole
length of the porous portion observed at the medulla as white
streaks was measured. The hair after treatment was subjected to
similar measurement. From the ratio of pores before treatment to
those after treatment, the disappearance ratio or formation ratio
of pores was determined.
[0035] (ii) Evaluation Methods of Smoothness, Improvement of
Luster, Dryness and Styling Ease of the Hair
[0036] A hair bundle (20 g) was washed sufficiently with 1 g of a
plain shampoo (prepared using sodium polyoxyethylene (2.5)
laurylether sulfate and diethanolamide). After water was drained
off roughly, 2 g of a hair conditioner was applied to the hair
bundle. The hair bundle was rinsed for 30 seconds with water of
40.degree. C. running at 6 liter/min, towel dried and dried
sufficiently by a hot wind of a drier for 2 to 3 minutes.
[0037] Organoleptic evaluation was conducted by a panel of 20
experts in accordance with the below-described standards and
ranking was made based on the average of their scores.
[0038] Smoothness (Upon Rinsing and After Drying)

According to the organoleptic evaluation, the hair treated with
them had excellent smoothness, improved luster, and good styling

Example 2
[0069] In a similar manner to (i) of Example 1, treatment was
performed four times (hot-air drying time by a drier was increased
to 5 minutes) by using 0.5 g of a hair bundle free from pores
inside of the hair and hair conditioners of the invention product
and comparative product. The formation ratio of pores after
treatment was measured in a similar manner and results are shown in
Table 2.

indicating that they have marked effects for preventing formation
of pores.
[0071] According to the organoleptic evaluation, use of the hair
conditioner according to the present invention prevented dryness of
the hair, thereby bringing about good styling ease even after drier
treatment for 5 to 10 minutes.
