Abstract

A liquid, transparent composition comprising microcapsules with at least one odor modulator compound, the composition also comprising at least one perfume. Even though the composition is in capsules, the transparent liquids can be produced using intense and lasting fragrances in the substrate.

First claim

What is claimed is:

1 . A liquid, transparent composition, comprising
a) at least one odorant
and
b) from 0.00001 to 0.2 wt. % microcapsules, comprising at least one odor modulator compound, wherein each individual modulator compound
i) is contained, based on the total of all the odorants contained in the composition, in an amount of from 2 wt. % to 0.000001 wt. %, and
ii) contains at least one heteroatom, wherein the at least one heteroatom is selected from N, O, S, Si, Se, F, Cl, Br or I, and
iii) has a molecular weight of lower than 250 g mol −1 , and
wherein the composition has an efficiency factor of at least 1.15 on account of the at least one odor modulator compound, wherein the efficiency factor is calculated according to the following formula:

E
=

P
GMV

P
+
1

≥
1.15

where E=efficiency factor and P=number of persons trained in odors that deemed the composition having an odor modulator compound (P GMV ) or not having an odor modulator compound (P) to be more intense, wherein the sum of P GMV and P is at least 34.

2 .
