  • Conditioning shampoo compositions having improved silicone deposition
    Patent number: 6200554
    Abstract: Disclosed are conditioning shampoo compositions which provide improved hair or skin conditioning performance. These compositions comprise a detersive surfactant, select ethoxylated fatty alcohols having a fatty alcohol moiety containing from about 6 to about 30 carbon atoms and an ethoxylate chain containing from about 5 to about 150 moles of ethoxylation, a nonvolatile conditioning agent, preferably a nonvolatile silicone conditioning agent, having an average particle size of from about 5 um to about 2000 um, and water. The select ethoxylated fatty alcohols provide improved hair or skin conditioning by improving silicone deposition of large particle conditioning agents onto the hair or skin.
