Fragrance Constraints in Candles

Fragrance creation: No major technical constraints

To avoid fumes in the air

Citrus / hesperidic notes are difficult to create

Solubility issue with water soluble materials

Choice of solvent (TEC for crystallised materials)

1. Plug-Ins

Technology : By the use of heat, the perfume emanates in the air through a wick from

a liquid reservoir.

Pros : Very good performance (most performing A/F)

Visible end of life signal

Adjustable / Refillable

Multi room usage

Linear diffusion if fragrance well structured

Cons : Technical constraints

Not portable

32/33

32 Air Care

FAN versus HEAT

Temperature increase influences the vapour pressure of perfumery

raw materials particularly the bottom notes

Heated systems allow a better diffusion of heavier components than

fan driven devices

The best way ensure a good diffusion of bottom notes is the use of

heat

Air flow generated with a fan remains marginal versus convection
