Abstract

Compositions and personal care articles are described comprising a complexed perfume and a coating material which acts to retain the perfume in the complexed state and to keep out other competing materials.

1 . A composition comprising a fragrance-releasing complex of an entrapment material and a fragrance; and an encapsulation material, wherein the encapsulation material comprises a non-ionic surfactant; and wherein the weight ratio of fragrance-releasing complex to encapsulation material is greater than 1.  
   
   
       2 . The composition according to  claim 1 , wherein the non-ionic surfactant comprises block copolymers of ethylene oxide and propylene oxide, polyalkylene oxide siloxanes, partially or fully hydrogenated polyoxyethylene castor oil ethers or polyoxyethylene hardened castor oil ethers, sorbitan esters of long chain fatty acids, polyethoxylated fatty alcohol surfactants, glycerol mono-fatty acid esters, fatty acid esters of polyethylene glycol, fluorocarbon surfactants and mixtures thereof.  
   
   
       3 . The composition according to  claim 1 , wherein the entrapment material comprises capsules, microcapsules, nanocapsules, liposomes, film-formers, cyclic oligosaccharides, materials capable of transforming fragrances into pro-perfumes and mixtures thereof.
