Compositions are provided that include a matrix and a polymeric composite particles disposed in the matrix. The polymeric composite particles include a porous polymeric core and a fragrance positioned within the porous polymeric core. Polymeric composite particles are also provided including a porous polymeric core, a fragrance positioned within the porous polymeric core, and a coating layer around the porous polymeric core. Further, a method of determining a minimum temperature of a composition is provided including providing a composition including polymeric composite particles disposed in a matrix, heating the composition, releasing at least a portion of the fragrance as a vapor from the porous polymeric core of the polymeric composite particles at or above the minimum temperature, and detecting at least a portion of the fragrance vapor in a location outside of the matrix.

Suggested is a cooling preparation comprising phenylalkenals and homovanillic acid esters.

Embodiments in accordance with the present invention relate generally to a variety of norbornene derivatives exhibiting olfactive properties and are suitable as fragrance ingredient in a number of personal care products including lotions and shampoo. More specifically, this invention relates to various fragrance compositions containing one or more of a compound of formulae (IA) or (IB): ##STR00001##
Wherein m, R.sub.1, R.sub.2 and R.sub.3 are as defined herein. The compounds of formulae (IA) or (IB) are useful as perfume augmenting, modifying, enhancing, and imparting compositions. The compositions of this invention are therefore useful in a variety of products including shampoo, lotions, skin care products, hair products, sanitary products, among various other personal care products.
