  • Publication number: 20260071148
    Abstract: Hard surface, namely floor coating compositions free of fluoro-surfactants and free of zinc cross-link agents are disclosed. More particularly, hard surface, namely floor coating compositions containing an organic polymer comprising (i) styrene or vinyl toluene and at least one monoethylenically unsaturated acid or anhydride, (ii) acrylic polymers or modified acrylic polymers, or (iii) combinations thereof as the floor coating material with a plasticizing agent, solvent and/or a coalescent and/or cosolvent, without the use of zinc cross-link agents and fluoro-surfactants are disclosed. The aqueous compositions and methods of use provide desired floor coating characteristics with enhanced sustainability profiles.

  • Publication number: 20250011685
    Abstract: The invention relates to neutral cleaning compositions comprising a surface modification polymer to beneficially aid in removing typical bathroom soils, such as hard water deposits, at a neutral pH. The neutral cleaning compositions effectively remove and/or otherwise assist in general cleaning of difficult bathroom soils without the harsh effects of a traditional acidic cleaning composition and without requiring PPE. Additionally, use of the cleaning composition beneficially aids in and/or improves subsequent cleanings.
