  • Patent number: 11421048
    Abstract: Disclosed are staged emulsion polymers comprising a crosslinked first stage polymer and a subsequently polymerized linear or slightly crosslinked second stage polymer segment. The staged emulsion polymers possess a dual activation mechanism and provide desirable rheological, clarity, and aesthetic properties in aqueous and aqueous surfactant containing compositions.

    Date of Patent: August 23, 2022
    Assignee: Lubrizol Advanced Materials, Inc.
    Inventors: Shui-Jen Raymond Hsu, Dongcui Li, Sinan Li, Robert Jacobs
  • Patent number: 11337906
    Abstract: The present disclosure relates to hair care and conditioning compositions; and to methods for conditioning, managing, and/or styling the hair using the compositions. The hair conditioning and managing compositions are substantially anhydrous and include: propylene glycol; one or more monoalcohols having from 2 to 6 carbon atoms; one or more cationic surfactants; and one or more fatty compounds. The compositions are solubilized, non-emulsified compositions until applied to wet or damp hair, whereupon the compositions form a lamellar phase in situ.

  • Patent number: 11254766
    Abstract: A crosslinked, nonionic, amphiphilic polymer is prepared by polymerizing a monomer mixture comprising an amphiphilic additive. The obtained polymer is useful for forming a clearer yield stress fluid in combination with a surfactant. The yield stress fluid is capable of suspending insoluble materials in the presence of electrolytes, perfumes, fragrances and/or organic acid preservatives.

  • Publication number: 20200375854
    Abstract: Disclosed are semi-solid gel compositions comprising (a) a gelling oil phase comprising: i) at least one oil gelator; ii) at least one fatty alcohol; and iii) at least one fatty compound other than (ii); wherein said gelling oil phase is present in an amount of from at least about 50% by weight, relative to the weight of the total composition; and (b) a lamellar crystalline aqueous gel phase comprising: i) water and optionally at least one polyol present in an amount up to about 50% by weight, relative to the weight of the total composition; ii) at least one lamellar crystalline phase structurant; and iii) at least one emulsifier. The disclosure also relates to methods of treating keratinous substrates.
