Abstract
Abstract COMPOSITIONS COMPRISING FINELY DIVIDED MATERIALS HAVING FRAGRANCE INGREDIENTS, I.E. PERFUME ASSOCIATED THEREWITH ARE IMPROVED IN THE ABILITY TO RETAIN SUCH FRAGRANCES WITHOUT DETERIORATING OVER A PERIOD OF TIME BY TREATING SAID MATERIALS WITH A CHELATING SUBSTANCE. IT IS POSTULATED THAT VARIOUS COMPONENTS OF THE FINELY DIVIDED MATERIALS THAT WOULD OTHERWISE REACT WITH SAID PERFUME AND DEGRADE IT ARE INACTIVATED. BOTH THE PROCESS OF INACTIVATION AND THE COMPOSITIONS RESULTING THEREFROM EMBODY THE INVENTIVE CONCEPT.
