  • Publication number: 20160130745
    Abstract: Freshening compositions comprising a malodor binding polymer, a malodor counteractant comprising at least one aliphatic aldehyde, and an aqueous carrier, wherein the composition is essentially free of any material that would soil or stain fabric; and methods thereof are provided. In some embodiments, the malodor binding polymer comprises a homopolymeric polyethylenimine having a molecular weight of about 1,000 to about 2,000,000. Such freshening compositions may be used to reduce malodor and/or microbes on inanimate surfaces or in the air.
