Definitions

  • compositions are commercially available or otherwise known in the shampoo art. These compositions typically include particulate, crystalline antimicrobial agents dispersed and suspended throughout the composition. Antimicrobial agents used for this purpose include sulfur, selenium sulfide and heavy metal salts of pyridinethione. During the shampooing process, these antimicrobial agents deposit on the scalp to provide anti-dandruff activity.
  • anti-dandruff shampoos do not provide sufficient antimicrobial agent deposition during the shampooing process. Without such deposition, the antimicrobial agents simply rinse away during shampooing and therefore provide little or no anti-dandruff activity.
  • the detersive surfactants in these shampoo compositions which are designed to remove oil, grease, dirt, and particulate matter will also carry away particulate antimicrobial agents during rinsing, thus further decreasing deposition and anti-dandruff activity.
  • Deposition of particulate antimicrobial agents is especially difficult in anti- dandruff shampoo compositions containing crystalline suspending agents. These suspending agents help disperse and suspend particulate antimicrobial agents in the shampoo composition. These suspending agents, however, adversely affect lathering performance. It has therefore become conventional practice to enhance the lathering performance of these shampoos by increasing detersive surfactant concentrations or by adding foam boosters, both of which further decrease deposition of particulate antimicrobial agents from the shampoo compositions.
  • an anti-dandruff shampoo composition having improved deposition of antimicrobial agents (particularly particulate antimicrobial agents) as well as improved deposition of agents which impart a refreshing feeling to the scalp.
  • the present invention is directed to anti-dandruff shampoo compositions which comprise: (a) from about 7% to about 30% by weight of a detersive surfactant selected from the group consisting of anionic surfactant, amphoteric surfactant, and mixtures thereof; (b) from about 0.1% to about 10% by weight of an antimicrobial agent; (c) from about 0.5% to about 10% by weight of a suspending agent; (d) from about 0.01 % to about 1.0% by weight of a cationic guar polymer having a charge density of from about 0.1 to about 3meq/gm; (e) a cool-feeling agent selected from the group consisting of borneol, camphor, cineol menthane, glycosil-mono-mentyl-oacetate, menthol, 3-1-menthoxypropane-1-2- diol, menthyl malonate, 1-menthyl-3-hydroxybutyrate, menthyl salicylate, peppermint, spearmint, and mixture
  • the select cationic deposition polymers are especially effective in providing enhanced deposition of antimicrobial agents, especially particulate antimicrobial agents, from a shampoo composition.
  • the select polymers are cationic derivatives of guar gum which have been found to be most effective when used in combination with crystalline suspending agents and high levels of anionic, amphoteric or zwitterionic surfactant in an anti-dandruff shampoo composition.
  • the incorporation of cool-feeling agents in a shampoo composition comprising such select cationic deposition polymers provides improved deposition of the cool-feeling agents to the scalp.
  • Certain embodiments may also provide improved shelf stability. Without being bound by theory, it is believed the large size of the cationic guar polymer component improves phase stability of a shampoo comprising the cool-feeling agent.
  • Certain embodiments provide anti-dandruff treatment, as well as impart a cool-feeling sensation to the scalp of the user. Certain embodiments may provide high lathering in combination with improved deposition and/or improved stability of the cool-feeling agents.
