Description

Conditioning composition comprising hydrophobically modified crosslinked cationic thickening polymer

field of invention

The present invention relates to conditioning compositions comprising a hydrophobically modified crosslinked cationic thickening polymer, a surfactant system and a silicone compound. The conditioning compositions of the present invention have rheological properties suitable for conditioning compositions and provide conditioning benefits. The composition is especially suitable for hair care products, such as hair conditioning products for rinse-off use.

Background of the invention

A variety of conditioning compositions, such as hair conditioning compositions, skin conditioning compositions and fabric softeners, have been used on a variety of substrates, such as hair, skin and fabrics. One common method of providing conditioning benefits 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. For example, certain cationic surfactants, when used with certain high melting point fatty compounds, are believed to form a gel matrix with rheological properties suitable for conditioning compositions and suitable for providing a variety of conditioning benefits , especially when used in hair care products, which provide benefits such as smooth feel, softness and reduced tangling of wet hair, and softness and moist feel of dry hair.

Instead of forming the gel matrix described above, there is a need to use other methods to achieve rheological properties suitable for conditioning compositions while maintaining the conditioning benefits of the gel matrix.

Additionally, most of the aforementioned conditioning agents are also known to render the composition opaque. Accordingly, there is a need for conditioning compositions having a clear product appearance, ie, a transparent or translucent product appearance.

It is also known that most of the aforementioned conditioning agents weigh down the hair when included in hair care compositions. For those consumers who wish to maintain or increase hair volume, such as those with finer hair, weighing down the hair is undesirable. Accordingly, there is a need for hair conditioning compositions that provide conditioning benefits without weighing down the hair.

There is also a need for a conditioning composition that, when used in the form of a rinse-off product, especially a rinse-off hair conditioner product, provides a conditioning benefit that is perceived by the consumer as easy to rinse off. Conditioner compositions comprising the above-described gel base also provide a long-lasting smooth feel upon rinsing, which is undesirable for some consumers who prefer a clean feel. Accordingly, there is a need for a conditioning composition which, when rinsed from the hair, leaves the hair easily, giving a clean feel, while still depositing a sufficient amount of conditioning agent on the hair.

Based on the foregoing, there is a need for a conditioning composition that, when used in hair care products such as hair conditioning products, can be cured by using methods other than gelling of cationic surfactants and high melting point fatty compounds. The gel base has the right rheological properties while providing conditioning benefits, especially wet softness and tangling reduction. There is also a need for conditioning compositions that are adapted to provide additional benefits such as a sheer product appearance, no hair weighing down, and an easy-rinse feel while providing the aforementioned rheological benefits and conditioning benefits.

None of the prior art offers all of the advantages and benefits of the present invention.
