Definitions

  • the present invention relates to a personal care composition containing a cationic cellulose polymer and an anionic surfactant system. More specifically, it relates to a personal care composition containing an anionic surfactant system with specific ratios of ethoxylate and sulfate such that when combined with the cationic cellulose polymer, maximized levels of coacervate are achieved in use.
  • compositions comprising various combinations of detersive surfactant and conditioning agents are known. These products typically comprise an anionic detersive surfactant in combination with a conditioning agent such as silicone, hydrocarbon oil, fatty esters, or combinations thereof. These products have become more popular among consumers as a means of conveniently obtaining hair and skin conditioning and cleansing performance all from a single personal care product.
  • a conditioning agent such as silicone, hydrocarbon oil, fatty esters, or combinations thereof.
  • conditioning agents are not provided onto hair and skin during the cleansing process. Without such deposition, large proportions of conditioning agent are rinsed away during the cleansing process and therefore provide little or no conditioning benefit. Without sufficient deposition of the conditioning agent on the hair and skin, relatively high levels of conditioning agents may be needed in the personal cleansing composition to provide adequate conditioning performance. However, high levels of a conditioning agent can increase raw material costs, reduce lathering, and present product stability concerns.
  • Obtaining good deposition of a conditioning agent is further complicated by the action of detersive surfactants in the personal care composition.
  • Detersive surfactants are designed to carry away or remove oil, grease, dirt, and participate matter from the hair and skin. In doing so, the detersive surfactants can also interfere with deposition of the conditioning agent, and both deposited and non deposited conditioning agent can be removed during rinsing. This further reduces deposition of the- conditioning -agent onto-the hair and -skirr-after rinsing, thus further reducing conditioning performance.
  • One known method for improving deposition of a conditioning agent involves the use of certain cationic deposition polymers. These polymers may be synthetic or natural cellulosic or guar polymers that have been modified with cationic substituents. The cationic charge density of such polymers, especially when used in a personal care composition, is minimized so as to avoid incompatibility with anionic materials in the product such as anionic surfactant. Thus, most personal care compositions that contain both an anionic detersive surfactant and a cationic deposition polymer have a relatively low level of coacervate conditioning. A need still exists for improved conditioning performance in personal care compositions.

Analytical techniques have been developed to measure percent ethoxylation or percent sulfates within surfactant systems. The level of ethoxylate and the level of sulfate representative of a particular surfactant system is calculated from the percent ethoxylation and percent sulfates of individual surfactants in the following manner:
  • Level of Ethoxylate in a composition percent ethoxylation multiplied by percent active ethoxylated surfactant.

  • Level of Sulfate in Example 1 0.18830 multiplied by 10 (% active ethoxylated surfactant) plus 0.266845 multiplied by 4 (% active non-ethoxylated surfactant). Thus the level of sulfate in Example 1 's composition is approximately 2.95.
