A progressive liquid fill capacity indicator located inside a vapor diffusion membrane liquid reservoir that utilizes index refraction matching of liquid contact to components, dyes, and surface tension gradients. This fill capacity indicator is low cost and reliable. It enables users to visually assess readiness and remaining liquid capacity to deliver attraction, masking, and repulsion scent vapors from wearable and stationary devices to repel or attract mosquitos and arthropods.

A scented color-changing system for revealing a hidden message, brand, picture, and the like on a substrate such as a paper when a fragrance is applied or released on the substrate. The hidden message contains a color former such as a leuco dye and the fragrance contains a color developer such as zinc chloride that reacts with the color former to reveal the message. The fragrance can be sprayed on the substrate or released from microcapsules embedded in or disposed on the substrate by rupturing the microcapsules. The scented color-changing system is particularly suited for use with fragrance test strips, advertising mailers, magazine inserts, and the like.

A volatile composition having: (i) greater than 30% of a scented hydrophobic material by weight of the volatile composition, wherein the scented hydrophobic material comprises one or more volatile compounds; and (ii) greater than 20% of a regulating scent intensity (RIS) composition by weight of the volatile composition.

The RIS composition has at least two of: a first regulating scent intensity component (RIS component) having a high average vapor pressure (VP); a second RIS component having a medium average VP; and a third RIS component having a low average VP;

The average VP of each of said one or more volatile compounds is lower than at least one of the high, medium and low average VPs of the first, second and third RIS components at the same temperature.

A scent intensity regulating composition (RIS composition). The RIS composition includes at least two of:

a first scent intensity regulating component (RIS component) having an average vapor pressure (VP) greater than 0.3 Torr at 25° C.;
a second RIS component having an average VP from 0.07 to 0.3 Torr at 25° C.; and
a third RIS component having an average VP from 0.0099 to 0.07 Torr at 25° C.

Each of the first, second, and third RIS components is characterized by an Odor Detection Threshold (ODT) of greater than 20 ppb.
