摘要：
Freshening compositions comprising a malodor binding polymer 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. In some embodiments, the freshening composition includes a buffering agent providing a pH of about 6 to about 8. Such freshening compositions may be used to reduce malodor and/or microbes on inanimate surfaces or in the air.
