Abstract
This invention provides a highly concentrated aqueous softener composition which has improved viscosity characteristics and an excellent long-term storability. The softener composition comprises 7 to 50% by weight of cationic softening agent, 0.05 to 10% by weight of alkylene oxide adducted nonionic surfactant having at least one unsaturated bond in its molecule, 0.005 to 5% by weight of inorganic electrolyte, and the balance of water.
