Description
AA-605M/VB ~ 02444206 2003-10-09 t t7 HAIR CONDITIONING COMPOSITION COMPRISING THICKENING POLYMER
AND CATIONIC SURFACTANT
Field of Invention The present invention relates to a hair conditioning composition comprising a thickening polymer, a cationic surfactant, and the composition being substantially free of water-insoluble high melting point oily compounds. The hair conditioning composition of the present invention can provide conditioning benefits such as softness and smoothness, while leaving the hair with a clean feel.
Background of the Invention Human hair becomes soiled due to its contact with the surrounding environment and from the sebum secreted by the scalp. The soiling of hair causes it to have a dirty feel and an unattractive appearance. The soiling of the hair necessitates shampooing with frequent regularity.
Shampooing cleans the hair by removing excess soil and sebum. However, shampooing can leave the hair in a wet, tangled, and generally unmanageable state. Once the hair dries, it is often left in a dry, rough, lusterless, or frizzy condition due to removal of the hair's natural oils and other natural conditioning and moisturizing components. The hair can further be left with increased levels of static upon drying, which can interfere with combing and result in a condition commonly referred to as "fly-away hair", or contribute to an undesirable phenomena of "split ends", particularly for long hair.
A variety of approaches have been developed to condition the hair. A common method of providing conditioning benefit to the hair is through the use of hair conditioning agents such as cationic surfactants and polymers, high melting point oily compounds, low melting point oils, silicone compounds, and mixtures thereof. Most of these conditioning agents are known to provide various conditioning benefits such as moisturized feel, softness, and static control to the hair.
A common method of providing conditioning benefit to the hair is through the use of hair conditioning agents such as cationic surfactants and polymers, silicone conditioning agents, hydrocarbon oils, and fatty alcohols. Cationic surfactants and polymers, hydrocarbon oils and fatty alcohols are known to enhance hair shine and provide moistness, softness, and static control to the hair. However, such components can also provide greasy or waxy feeling on wet and dry hair.
Furthermore, most of these conditioning agents are also known to weigh down the hair, when these conditioning agents are included in a hair conditioning composition. The weighed down hair gives an appearance of reduced bulk hair volume. For consumers who desire maintaining or increasing hair volume such as consumers having fine hair, the effect of hair weighing down is not desirable. The term "Increasing hair volume" 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, increasing hair volume as used herein relates to increase of the bulk of the hair volume.
Consumers having fine hair have the desire to achieve increased hair volume while controlling undesirable fly-away of the hair.
Based on the foregoing, there remains a desire for hair conditioning compositions which provide conditioning benefits such as softness and smoothness, while leaving the hair with a clean feel.
There also exists a desire for hair conditioning compositions being easy to rinse-off, when the compositions are in the form of rinse-off products.
There further exists a desire for hair conditioning compositions which provide the above benefits, while not weighing down the hair.
None of the existing art provides all of the advantages and benefits of the present invention.
Summary of the Invention The present invention is directed to a hair conditioning composition comprising by weight:
(a) from about 0.01 % to about 10% of a thickening polymer;
(b) from about 0.05% to about 10% of a cationic surfactant; and (c) an aqueous carrier;
and wherein the composition is substantially free of a water-insoluble high melting point oily compound.
The composition of the present invention can provide conditioning benefits such as softness and smoothness, while leaving the hair with a clean feel.
These and other features, aspects, and advantages of the present invention will become better understood from a reading of the following description, and appended claims.

The hair conditioning compositions of "Ex.l" to "Ex.7" as shown above can be prepared by any conventional method well lalown in the art. They are suitably made as follows:
Deionized water is heated to 85°C. The polymeric materials, cationic surfactants, and if included, nonionic surfactants are added to water with agitation. The water is maintained at a temperature about 85°C until the components are homogenized and no solids are observed. Then the mixture is cooled to about SS°C, and the remaining components such as silicones, perfume, and preservatives, if included, are added with agitation. After it is homogenized, it is cooled to room temperature.
Examples 1 through 7 are hair conditioning compositions of the present invention which are particularly useful for rinse-off use. These examples have many advantages. For example, the compositions of "Ex.l" through "Ex.7" can provide conditioning benefits to the hair such as softness and smoothness, and leave the hair with a clean feel. They can also provide benefits such as being easy to rinse-off, and not weighing down the hair. They can also provide slippery feel on wet hair.
AND CATIONIC SURFACTANT
Field of Invention The present invention relates to a hair conditioning composition comprising a thickening polymer, a cationic surfactant, and the composition being substantially free of water-insoluble high melting point oily compounds. The hair conditioning composition of the present invention can provide conditioning benefits such as softness and smoothness, while leaving the hair with a clean feel.
Background of the Invention Human hair becomes soiled due to its contact with the surrounding environment and from the sebum secreted by the scalp. The soiling of hair causes it to have a dirty feel and an unattractive appearance. The soiling of the hair necessitates shampooing with frequent regularity.
Shampooing cleans the hair by removing excess soil and sebum. However, shampooing can leave the hair in a wet, tangled, and generally unmanageable state. Once the hair dries, it is often left in a dry, rough, lusterless, or frizzy condition due to removal of the hair's natural oils and other natural conditioning and moisturizing components. The hair can further be left with increased levels of static upon drying, which can interfere with combing and result in a condition commonly referred to as "fly-away hair", or contribute to an undesirable phenomena of "split ends", particularly for long hair.
A variety of approaches have been developed to condition the hair. A common method of providing conditioning benefit to the hair is through the use of hair conditioning agents such as cationic surfactants and polymers, high melting point oily compounds, low melting point oils, silicone compounds, and mixtures thereof. Most of these conditioning agents are known to provide various conditioning benefits such as moisturized feel, softness, and static control to the hair.
A common method of providing conditioning benefit to the hair is through the use of hair conditioning agents such as cationic surfactants and polymers, silicone conditioning agents, hydrocarbon oils, and fatty alcohols. Cationic surfactants and polymers, hydrocarbon oils and fatty alcohols are known to enhance hair shine and provide moistness, softness, and static control to the hair. However, such components can also provide greasy or waxy feeling on wet and dry hair.
Furthermore, most of these conditioning agents are also known to weigh down the hair, when these conditioning agents are included in a hair conditioning composition. The weighed down hair gives an appearance of reduced bulk hair volume. For consumers who desire maintaining or increasing hair volume such as consumers having fine hair, the effect of hair weighing down is not desirable. The term "Increasing hair volume" 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, increasing hair volume as used herein relates to increase of the bulk of the hair volume.
Consumers having fine hair have the desire to achieve increased hair volume while controlling undesirable fly-away of the hair.
Based on the foregoing, there remains a desire for hair conditioning compositions which provide conditioning benefits such as softness and smoothness, while leaving the hair with a clean feel.
There also exists a desire for hair conditioning compositions being easy to rinse-off, when the compositions are in the form of rinse-off products.
There further exists a desire for hair conditioning compositions which provide the above benefits, while not weighing down the hair.
None of the existing art provides all of the advantages and benefits of the present invention.
Summary of the Invention The present invention is directed to a hair conditioning composition comprising by weight:
(a) from about 0.01 % to about 10% of a thickening polymer;
(b) from about 0.05% to about 10% of a cationic surfactant; and (c) an aqueous carrier;
and wherein the composition is substantially free of a water-insoluble high melting point oily compound.
The composition of the present invention can provide conditioning benefits such as softness and smoothness, while leaving the hair with a clean feel.
