Abstract
A perfume-containing water-in-oil microemulsion is provided which is capable of being mixed with an aqueous fabric softener base composition to provide perfume thereto. The use of the defined microemulsion enables the addition of perfume as well as other cosmetic attributes to an aqueous base composition under conditions of low shear while avoiding any problems of gelation or physical instability in the finished fabric softener product.
