  • Publication number: 20210220243
    Abstract: The invention is directed to a hydratable concentrated surfactant composition. The composition is pourable, easy to dilute, substantially free of sulfate and oil, comprises a C6-C14 acid, alcohol or both, anionic surfactant and an amphoteric surfactant, zwitterionic surfactant or both. The composition is in lamellar phase and thickens and transforms to an isotropic phase upon dilution. The composition can be used as a concentrate in small volumes and diluted as used and needed or can be diluted with water in refill packaging to ensure a reduction in plastic waste.

  • Publication number: 20210045987
    Abstract: The invention relates to stable, mild and moisturizing lamellar liquid cleansing compositions which possess a lotion-like appearance conveying signals of enhanced moisturization. However, these liquids often are either unstable or cause poor lather production and other sensory deficits The use of a specific ratio of total acyl isethionates to acyl glutamates or other divalent anionic surfactant in a structured liquid product improve stability and lather production, mildness and acceptable odor.

  • Patent number: 5962398
    Abstract: The present invention relates to isotropic liquids containing anionic polymers wherein the polymers are not hydrophobically modified and can still be incorporated into the compositions. By using anionic/nonionic compositions in which more than 25% of nonionic is sugar surfactant, the polymers can be incorporated without such modification.

  • Patent number: 5776883
    Abstract: The present invention relates to liquid detergent compositions comprising linear or cross-linked, water soluble, highly salt-tolerant, nonionic polymers of MW 10,000 to 1,000,000 Daltons which, when added to structured heavy duty liquids makes the liquid highly shear thinning without decreasing pour viscosity of the composition or increasing it to a point where it is too thick. The compositions are also stable.

  • Patent number: 5753152
    Abstract: The present invention relates to a process for preparing matrix capsules having hydrocarbon cores sufficiently large to contain large size particle actives which process comprises dispersing actives in hydrocarbon core material, and dispersing the active containing hydrocarbon in a polymer solution to form a polymer matrix emulsion of drops of said core material in said solution. The key to the invention is to obtain the dispersion by utilizing low shear rates previously uncontemplated using the standard shearing machinery of the art. This in turn is accomplished by maintaining the core within defined rheological parameters. By using lower shear rates, applicants were unexpectedly able to prepare capsules capable of stably incorporating large size actives in the core.
