In a fragrance and/or aroma composition for the targeted release of fragrances and/or aromas in the form of a solid lipid nanoparticle (SLN) dispersion, in which lipid-based nanoparticles are present which are stabilized by an emulsifier monolayer, one or more membrane layers or other auxiliaries, the fragrances and/or aromas are included in the nanoparticles and/or in the emulsifier monolayer or the membrane layers.

Compositions for the targetted release of fragrances and aromas

The present invention is directed to an emulsion base for formulating cosmetic and dermatological compositions. The emulsion base has particular surfactant and/or emulsifier ratios such that a wide range of compositions with varying forms and additional components can be formulated without changing the ratio or amount of the primary and/or co-surfactant/emulsifier in the emulsion base or the amount of the emulsion base in the final composition. The emulsion base can be used in a system of formulating cosmetic and dermatological compositions.
