  • Composition and method of producing personal care compositions with improved deposition properties
    Patent number: 10058498
    Abstract: The presently disclosed and/or claimed inventive concept(s) relates generally to the use of nonionic hydrophobically modified polysaccharides in personal care and household care compositions. More specifically, but not by way of limitation, the presently disclosed and/or claimed inventive concept(s) relates to the use of hydrophobically-modified cellulose ethers, such as hydrophobically-modified hydroxyethylcellulose (HMHEC) polymers in personal care and household care compositions. These compositions show pronounced syneresis in aqueous solutions or in the presence of surfactants, including nonionic surfactants and anionic surfactants such as lauryl sulfate (LS) and lauryl ether sulfate (LES). It is also contemplated that the surfactants used in the compositions be sulfate free and/or multi-tailed.
    Type: Grant
