FABRIC CARE COMPOSITION CONTAINING HYDROPHOBICALLY MODIFIED POLYALKYLENE IMINE AS A COLOR-FIXING POLYMER Russian patent published in 2023 - IPC C11D3/00 C11D3/37 

FIELD: fabric care.

SUBSTANCE: fabric care composition contains (i) at least one hydrophobically modified polyalkylene imine at a concentration of 0.01 to 30% by weight of the composition, wherein the hydrophobically modified polyalkylene imine contains a polyalkylene imine backbone having a weight average molecular weight greater than or equal to 200 g/mol and less than 1000 g/mol, and hydrophobic fragments that are covalently attached to the backbone of the polyalkylene imine; and (ii) at least one non-ionic, anionic and/or cationic surfactant. Also disclosed is a method for providing a color protection effect during washing and/or treatment of dyed fabrics, the use of a composition for a color protection effect during washing and/or treatment of dyed fabrics, and for fabric care products.

EFFECT: group of inventions provides a color-fixing polymer that contributes to the effective fixation of dyes in the processes of washing and/or processing linen, while demonstrating better and wider compatibility with laundry compositions.
