  • LOW VISCOSITY CELLULOSICS IN HAIR CARE COMPOSITIONS
    Publication number: 20170290759
    Abstract: Provided are hair care compositions comprising: (a) a cellulose ether having (i) a methoxy substitution of from 21 to 42 weight % based upon the weight of the cellulose ether, (ii) a hydroxypropyl substitution of from 0 to 32 weight % based upon the weight of the cellulose ether, (iii) a viscosity of from 15 cP to less than 4,000 cP in a two percent aqueous solution at 20° C., and (iv) either a gelation temperature of greater than 45° C. or a hydration temperature of 25° or higher; and (b) at least one hair fixative polymer, conditioning agent, or humectant.

  • Alkyd dispersion, and a process for producing the same
    Patent number: 9200177
    Abstract: The instant invention provides a high-solid, solvent-free alkyd dispersion, and a continuous process for producing the same. The aqueous alkyd dispersion, according to the present invention comprises (a) from 40 to 70 percent by weight of one or more alkyds based on the total weight of the dispersion, wherein each one or more alkyds has an acid value of less than 20 and a molecular weight (Mn) in the range of greater than 1000 Dalton; (b) from less than 10 percent by weight of one or more surfactants, based on the total weight of the dispersion; and (c) from 30 to 55 percent by weight of water, based on the total weight of the dispersion; and the dispersion has an average particle size diameter in the range of 0.05 to 5 ?m.
