Embodiment

[0221] The following are non-limiting examples of anti-dandruff and conditioning shampoo compositions of the present invention. The provision of these embodiments is only for the purpose of illustration, and cannot be interpreted as a limitation of the present invention, because many changes can be made to the present invention without departing from the spirit and scope of the present invention, which are common skills in the art people can recognize. In these examples, all concentrations are percent by weight unless otherwise specified. The term "minor substances" as used herein refers to those optional substances such as preservatives, viscosity regulators, pH regulators, fragrances, foam boosters and the like. It will be apparent to those of ordinary skill in the art that the selection of these minor materials will vary with the physical and chemical characteristics selected to prepare the particular ingredients of the present invention.

Abstract

Disclosed are shampoo compositions that provide a superior combination of anti-dandruff efficacy and conditioning, and a method of cleansing and conditioning the hair comprising applying to the hair an effective amount of said compositions. The anti-dandruff and conditioning shampoos comprise: (A) from about 5 % to about 50 %, by weight of the composition, of an anionic surfactant; (B) from about 0.01 % to about 10 %, by weight of the composition, of a non-volatile conditioning agent; (C) from about 0.1 % to about 4 %, by weight of the composition, of an anti-dandruff particulate; (D) from about 0.02 % to about 5 %, by weight of the composition, of a cationic guar derivative; (i) wherein said cationic guar derivative has a molecular weight from about 50,000 to about 700,000; and (ii) wherein said cationic guar derivative has a charge density from about 0.05% meq / g to about 1.0 meq / g; and (E) water.

Description

technical field [0001] The present invention relates to shampoo compositions which provide a combination of superior antidandruff benefits and conditioning benefits. These compositions comprise anionic surfactants, conditioning agents, anti-dandruff particles, cationic polymers and water. Cationic polymers have certain molecular weight and charge density parameters that lead to improved efficacy of anti-dandruff shampoo compositions. Background of the invention [0002] Shampoo compositions comprising various combinations of detersive surfactants and conditioning agents, especially silicone conditioning agents, are well known in the art and commercially available. Many of these compositions have been found to provide excellent hair cleansing and conditioning benefits. For example, Pantene® shampoos with pro-vitamin conditioning agents in a formulation containing anionic surfactants, cationic polymers, and silicone conditioning agents provide outstanding ...
