Cyclodextrin derivatives with linear polymer ions, useful e.g. in textile washing- or cleaning mediums, cosmetic skin care medium such as deodorants, soaps, body lotions, after shaves and perfumes; and as hair caring agents are new

摘要

Cyclodextrin derivatives (I) with linear polymer ions (comprising quaternary nitrogen atoms in the repeating units of the polymer main chain and hydroxyl, thiol and/or amino groups bound to the polymer main chain or at the ends of the polymer main chain and where each polymer in (I) is formed from cyclodextrin molecules that is covalently bonded with hydroxyl groups) are new. Independent claims are also included for: (1) the preparation of (I); (2) use of (I) (with active agent binder and/or precipitating agent) in temporary equipment (II) of fibers, where the equipment is non-durable to washing-/cleaning process and removable, and the active agent is an aroma based material; (3) a method of temporary equipment (containing the fiber with active agent binder and/or precipitating agent) comprising contacting the fiber with a composition containing (I) and water; (4) fiber (particularly textile fibers or their related products, or hair) obtained by the method; and (5) a composition, used in the equipment, comprising (I) in a solvent or dispersion medium.
