Description

"COMPOSITION FOR CONDITIONING HAIR UNDERSTANDING POLYSACARIDES AND AMINOSILICONE HAIR"

FIELD OF INVENTION

The present invention relates to a hair conditioning composition comprising: a cationic or nonionic polysaccharide polymer, an aminosilicon, a cationic surfactant and a high melting point fatty compound.

The composition of the present invention may provide hair bulging benefits and ease of rinsing, while providing improved conditioning benefits.

BACKGROUND OF THE INVENTION

Several approaches have been developed for hair conditioning. A common method for providing hair conditioning benefit is through the use of conditioning agents such as surfactants and cationic polymers, high melting point fatty compounds, low melting point oils, silicone compounds and mixtures thereof. Most of these conditioning agents are known to provide several conditioning benefits.

Hair conditioning compositions comprising the conditioning agent described above may provide conditioning benefits such as softness and hydration in dry hair, but may also impart a heavy appearance to the hair. Hair with heavy appearance gives the impression of a reduction in total hair volume. For consumers who want a hair volume effect, such as those with thinning hair, it is not desirable to give their hair a heavy appearance. The term "hair bulk" for use in the present invention is not the same as creepy hair. The occurrence of creepy hair is due to an increase in the level of static, representing an increase in volume only in a small amount of hair as a whole, and is not desirable. On the other hand, hair bulk refers, for use in the present invention, to an increase in total hair volume. Consumers who have thinning hair want to get a volumination of their hair, while controlling for the unwanted occurrence of goose bumps. Therefore, there is a need for hair conditioning compositions that provide hair bulk benefits while providing hair conditioning benefits.

There is also a need for hair conditioning compositions that provide an improved rinse sensation while maintaining the benefits of conditioning, especially when there is formation of a gel matrix comprising cationic surfactants and high melting point fatty compounds. Hair conditioning compositions containing a gel matrix provide a slippery feel during hair rinsing and even after rinsing. The feeling of ease of rinsing is, for example, a rapid reduction in slippery sensation, and / or an increase in the sensation of cleanliness after the onset of hair rinsing. This reduction in slippery sensation, and / or increased feeling of cleanliness, may be a sign for consumers to stop rinsing hair conditioning compositions. Consumers who prefer essessinals may continue to rinse their hair treated with hair conditioning conditioning with a large amount of water until they experience these signs. However, this rinsing activity results in less deposition of conditioning agents on the hair and therefore less conditioning benefits to dry hair. Therefore, there remains a need for hair conditioning compositions that provide these signals more rapidly after the onset of hair rinsing, while allowing a sufficient amount of conditioning agents to be deposited on the hair, and / or maintaining the conditioning benefits.

Japanese Patent Application Publication2004-143093 discloses a hair conditioning composition comprising condensed polyalcohols having a viscosity of 4 to 100 Pa.s at 25 ° C, oily agents with a melting point of 30 to 55 ° C, silicones with amino groups or The same derivatives, nonionic surfactants with polyoxyalkylene adjuncts, and saturated fatty alcohols, are said to provide sufficient hydration and emollient effect to damaged hair, while offering excellent touch properties such as less stickiness, lower natural weight, better feel in the combing with the fingers and softness.

Japanese Patent Publication 2004-143093 also discloses, in Example 21, a hair conditioning composition containing hydroxy propyl guar gum, cetostearyl alcohol, stearyl trimethyl ammonium chloride, and amino-modified silicone available under the tradename SM8704C from Dow Corning Toray.

However, it has been found that it is not yet easy to obtain hair conditioning compositions that provide benefits of hair bulging and ease of rinsing, while offering improved conditioning benefits.

Based on the foregoing arguments, there remains a need for hair conditioning compositions that provide hair bulging benefits and ease of rinsing, while offering enhanced conditioning benefits.

None of the existing techniques offers all the advantages and benefits of the present invention.
