Abstract

Disclosed are encapsulated perfume compositions showing improved balance between storage stability in consumer products and perfume diffusivity from intact microcapsules deposited on substrates (so-called pre-rub performance), the compositions comprising a combination of long chain aldehydes having 10 carbon atoms or more and/or tertiary alcohols having 10 carbon atoms or more, in combination with blooming perfume ingredients.
