HAIR CONDITIONING COMPOSITION COMPRISING
POLYSACCHARIDE POLYMER AND AMINOSILICONE
FIELD OF THE INVENTION
The present invention relates to a hair conditioning composition comprising: a
cationic or
nonionic polysaccharide polymer; an aminosilicone; a cationic surfactant; and
a high melting
point fatty compound. The composition of the present invention can provide
hair volume-up
benefit and ease-to-rinse feel, while providing improved conditioning
benefits.
BACKGROUND OF THE INVENTION
A variety of approaches have been developed to condition the hair. A common
method
of providing conditioning benefit is through the use of conditioning agents
such as cationic
surfactants and polymers, high melting point fatty compounds, low melting
point oils, silicone
compounds, and mixtures thereof. Most of these conditioning agents are known
to provide
various conditioning benefits.
Hair conditioning compositions comprising the conditioning agent described
above can
provide conditioning benefits such as softness and moisturized feel on dry
hair, however, also
weigh down the hair. The weighed down hair gives an appearance of reduced bulk
hair volume.
For consumers who desire hair volume-up such as consumers having fine hair,
the effect of hair
weighing down is not desirable. The term "hair volume-up" as used herein is
not equal to fly-
away hair. Fly-away hair is due to the increased level of static, and
represents volume increase
of only very minor amount of the hair as a whole, and is not desirable. On the
other hand, hair
volume-up as used herein relates to increase of the bulk of the hair volume.
Consumers having
fine hair have the desire to achieve hair volume-up while controlling
undesirable fly-away of the
hair. Thus, there is a need for hair conditioning compositions providing hair
volume-up benefit
while providing conditioning benefits.
There also exists a need for hair conditioning compositions which provide
improved ease-
to-rinse feel, while maintaining conditioning benefits especially when forming
a gel matrix
comprised of cationic surfactants and high melting point fatty compounds. Hair
conditioning
compositions containing a gel matrix provide slippery feel during rinsing the
hair, even after
rinsing the hair. Ease-to-rinse feel are, for example, fast reduced slippery
feel, and/or increased
CA 02611244 2007-12-04
AA-734F/JW

clean feel after starting to rinse the hair. Such reduced slippery feel,
and/or increased clean feel
can be a signal for consumers to stop rinsing the hair conditioning
compositions. Consumers
who prefer such signals may keep rinsing the hair treated with hair
conditioning composition by a
large amount of water until they feel the signals. However, such rinsing
activity provides less
deposition of conditioning agents on the hair, thus less conditioning benefits
to the dry hair.
Thus, there remains a need for hair conditioning compositions which provides
such signals faster
after starting to rinse the hair, while remaining sufficient amount of
deposition of conditioning
agents on the hair and/or maintaining conditioning benefits.
Japanese Patent Laid-open 2004-143093 discloses a hair conditioning
composition
comprising: condensed polyalcohols having a viscosity of 4-100Pa=s at 25 C;
oily agents having
a melting point of 30-55 C; silicones having amino groups or derivatives
thereof; nonionic
surfactants having polyoxyalkylene adjunctions; and saturated fatty alcohols,
the composition
being said to provide sufficient moisturization and emollient to damaged hair,
while providing
excellent feel such as less stickiness, less unnatural heaviness, better
finger combing feel, and
softness. Japanese Patent Laid-open 2004-143093 also disclose, in Example 21,
a hair
conditioning composition containing: hydroxypropyl guar; cetostearyl alcohol;
stearyl trimethyl
ammonium chloride; amino-modified silicone with tradename SM8704C supplied
from Dow
Coming Toray.
However, it has been found that it is still not easy to obtain hair
conditioning
compositions which provide hair volume-up benefit and ease-to-rinse feel,
while providing
improved conditioning benefits.
Based on the foregoing, there remains a need for hair conditioning
compositions
providing hair volume-up benefit and ease-to-rinse feel, while providing
improved conditioning
benefits.
None of the existing art provides all of the advantages and benefits of the
present
invention.
