Description

Detailed Description of the Invention

The present invention relates to hair care compositions. In particular, the present invention relates to hair care compositions that provide good conditioning / gloss to the hair and reduce the sticky and greasy feel.

BACKGROUND hair of the invention are often exposed to a wide range of attacks that can cause damage. Examples of this attack include shampooing, rinsing, drying, heating, combing, styling, perming, coloring, and natural exposure. Thus, by rubbing the hair surface and removing the natural oils and other natural conditioning and moisturizing components of the hair, the hair often becomes dry, rough, dull or curly.

Various approaches have been developed to mitigate these conditions. These approaches include the use of ultra-mild shampoo compositions, the use of conditioning shampoos intended for both cleaning and conditioning in one product, and products of the rinse-off type and leave-on type (leave-on). ) The use of hair conditioning formulations such as products. The leave-on type of hair care formula offers additional advantages over other approaches. For example, a leave-on type formulation is more cost effective and longer lasting because the conditioning ingredients remain in the hair. The type of formulation that is left on is more convenient because the consumer can use the product at any time and does not have to wait to rinse the product. The product may also be applied to the part of the hair where the conditioning benefit is most needed.

It is well known to those skilled in the art that cationic polysaccharides provide conditioning benefits. For example, International Published Patents WO-A-97 / 35542, WO-A-
97/35545, WO-A-97 / 35546 all describe the use of cationic polysaccharides in conditioning shampoo compositions, to which reference is made. British Published Patent 2,211,192 describes the use of cationic polysaccharides in rinse-off conditioning compositions. German published patent 4,326,866 describes a composition for use before cutting hair, which comprises a cationic polysaccharide. Japanese patent JP-54138133 describes a hair product composition containing a polypeptide and cationic cellulose. However, these cationic polysaccharides are also known to cause stickiness or stickiness. This can cause the consumer to have a dirty or greasy feel on the hair, especially in leave-on conditioning compositions without a rinsing process.

Surprisingly, we have found that cationic polymers having a cationic charge density of greater than 1.5 meq / g and a weight average molecular weight greater than about 900,000 are tacky to the hair. It has been found to improve the effect of gloss / conditioning by suppressing the feel and greasiness. Without wishing to be bound by theory, it is believed that high cationic charge densities are more important for the polymer to provide the hair with sufficient conditioning benefits. Cationic groups interact with the negative charge of hair. The bonding sites increase as the proportion of said cationic groups on the polymer increases. The higher the interaction, the more likely the polymer backbone and hair fibers will be in intimate association, thereby reducing the depth of the hydrocarbon layer and interacting with other surfaces such as finger skin. The tendency to cause is reduced. Therefore, the close relationship between the polymer and the hair reduces the sticky feel and increases the gloss.

SUMMARY OF THE INVENTION The present invention provides a hair care composition comprising a cationic polymer having a charge density of greater than about 1.5 meq / g and a weight average molecular weight of greater than about 900,000. The composition of the present invention suppresses stickiness and greasiness, while at the same time providing good conditioning / gloss effects. All concentrations and ratios herein are by weight of the hair care composition unless otherwise stated. All averages are weight averages unless otherwise indicated.
