  • Publication number: 20230082890
    Abstract: A method for styling hair comprises placing the hair in a desired configuration and applying a hair styling composition to the hair. The hair styling composition comprises a powder of a multistage polymer of a soft polymer of Tg<40° C.; and a hard polymer having a Tg>40° C., and at least 10° C. higher than the Tg of the soft polymer wherein the hard polymer forms a complete or partial shell around the soft polymer the weight ratio of hard polymer to soft polymer being 1.01:1 to 2:1. After exposure to liquid water and drying at temperatures below 100° C., a maximum thermal transition temperature of the multistage polymer in an atmosphere of 0% relative humidity that differs by 20° C. or less from the maximum thermal transition temperature in an atmosphere of 75% relative humidity.

  • Publication number: 20170283607
    Abstract: There is provided a powder that comprises a multistage polymer that comprises (a) at least one soft polymer having glass transition temperature of 40° C. or lower, and (b) at least one hard polymer having glass transition temperature higher than 40° C., wherein the glass transition temperature of said hard polymer is at least 10° C. higher than the glass transition temperature of said soft polymer, wherein the weight ratio of said hard polymer to said soft polymer is from 1.01:1 to 100:1, and wherein said multistage polymer, after exposure to liquid water followed by drying at temperatures below 100° C., shows maximum thermal transition temperature in an atmosphere of 0% relative humidity that differs by 20° C. or less from the maximum thermal transition temperature in an atmosphere of 75% relative humidity.

  • Publication number: 20170014328
    Abstract: Provided are hair care compositions comprising: (a) a polyolefin oil blend comprising (i) at least one metallocene catalyzed polyolefin with a density above 0.90 g/cm3, (ii) at least one metallocene catalyzed polyolefin with a density equal to or below 0.90 g/cm3, and (iii) a cosmetically acceptable hydrocarbon oil; (b) a thickener; and (c) a humectant; wherein the high and low density polyolefins have an average melt index greater than 7, wherein the polyolefin blend is present in a range of from 0.1 to 1.4 weight % by weight of the composition, and wherein the composition is substantially free of ethylene-acrylic acid copolymer.
