Shampoo Containing a Gel Network and a Non-Guar Galactomannan Polymer Derivative

Abstract

Shampoo compositions comprise (a) from about 5% to about 50% of one or more detersive surfactants; (b) a dispersed gel network phase comprising: (i) at least about 0.05% of one or more fatty amphiphiles; (ii) at least about 0.01% of one or more secondary surfactants; and (iii) water; (c) at least about 0.05% of a galactomannan polymer derivative with a net positive charge and having a mannose to galactose ratio of greater than 2:1 on a monomer to monomer basis, wherein the galactomannan polymer derivative has: (i) a molecular weight from about 1,000 to about 10,000,000; and (ii) a cationic charge density from about 0.7 meq / g to about 7 meq / g; and (d) at least about 20% of an aqueous carrier; all by weight of the shampoo composition.

AI Technical Summary

Benefits of technology

The shampoo composition offers long-lasting moisturization, smooth feel, and enhanced manageability for dry hair, along with improved combing ease and reduced static, while being cost-effective by using a less expensive galactomannan polymer derivative.

Problems solved by technology

The soiling of hair causes it to have a dirty feel and an unattractive appearance.

However, shampooing can leave the hair in a wet, tangled, and generally unmanageable state.

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.”

Moreover, the cost of such cationic guar polymer is relatively high.

As a result, incorporation of cationic guar polymer can add to the manufacturing costs of such shampoo compositions.

Additionally, these shampoo compositions typically are good for delivering wet hair conditioning, but are not capable of delivering satisfactory dry hair smooth feel.
