Claims20
A scent patch comprising, in the following sequence, a backing layer, an adhesive layer, an adsorbing pad and optionally one or more protective liners, wherein:
- the backing layer is a fabric layer with a tensile strength >25 N/cm;
- the adhesive layer is a polymer layer resistant to ethanol/ethanolic compositions;
- the adsorbing pad comprises a non-woven pad which comprises a fragrance composition and which has an absorbance capacity for said fragrance composition of more than 20 g/100 cm2;
- the absorbing pad further comprises an anti-adhering layer opposite to the adhesive layer;
- the protective liner is a film with a thickness below 100 microns;
- and
- the non-woven pad and the adjacent adhesive layer are configured to interact during use of the scent patch, thereby creating tensions therebetween which result in short-term openings for gradually releasing the fragrance composition.
