Patent No. EP4466335 (titled "Use") was filed by Unilever on Dec 9, 2022. The application was issued on Sep 24, 2025.
Patent Summary
The invention relates to the use of a laundry liquid composition to increase fragrance deposition onto fabric during cleaning. The composition comprises a fragrance and a combination of two cellulases: a first cellulase and a second cellulase. Crucially, only the first cellulase comprises a cellulose binding domain (CBD), while the second cellulase does not. The composition may further include detersive surfactants (such as linear alkylbenzene sulfonates or alcohol ethoxylates), anti-foams, builders, polymeric cleaning boosters, soil release polymers, fluorescent agents, microcapsules, and polymeric thickeners, such as hydrophobically modified alkali swellable emulsion (HASE) copolymers. The system is applicable to various textiles, including natural and synthetic fibers, and suitable for heavy-duty, fine wash, or color care liquid detergents.
