Davana:
It is a oil derived from artemisia pallens, described as having a sweet, fruity odor. Depth: It is used in reference with the quality of a perfumes body and sophistication. A fragrance has depth when a leading identity of accord or character is noticeable during its evolution from top notes to dry down.Depth also refers to whether a scent is complex, sophisticated, rich or full-bodied. Destructive Distillation: A form of distillation where the material, usually wood, is heated in the absence of air to volatilise the essential oil. Usually the resulting oil is very dark with a smoky odour. e.g.. Birch Tar Oil, Styrax Pyrogenated Oil. Diffuser: A diffuser is an aromatherapy device that gently dispenses essential oils into the air. Diffusive : A term used to describe a fragrance, the odor of which spreads quickly and widely. The volatilization or evaporation and dispersal of a aroma material into the surrounding atmosphere . It fills the space. Also referred as lift to the perfume . In chemistry and physics this is normally related to the high Vapour Pressure and low molecular weight of a chemical. However, in perfumery it equally refers to a material or compounds ability to permeate the atmosphere with it's characteristic smell around it's source. Strangely, a materials ability to do this is not always related to it's Vapour Pressure. Some larger molecule materials (e.g.. Hedione, Iso E Super) not only demonstrate this ability but also 'hang' in the air. The molecules evaporate but instead of moving quickly from the vicinity of the source seem to move slowly away. Distillation : It is widely accepted oldest methods of separating oils from flowers in practice in recent times even . It is a heat-dependent process for separation and purification of a liquid mixture based on differences in vapor pressure of components of the mixture. In each case, the flowers or other sources of oil are changed into a still and heat is applied to separate the oil. One type involves direct contact between the plant material and boiling water. In another type, the heat source is steam that is blown through the flowers. The process involves vaporization of the more volatile component(s) and then condensation of the vapor back to a liquid. The water and oil are collected and as they separate, the oil is removed from the top. Dry: Alcohols help create this sort of scent not too sweet, more aromatic. A sensation produced by certain perfume ingredients which give a drying effect. Often associated with wood, iris notes and aroma chemicals with the active group 'formate'. Drydown : The final phase of a fragrance—the character that appears several hours after application. Perfumers evaluate the base notes and the tenacity of the fragrance during this stage. Also said to be the final phase of a perfume, the bottom note. The aroma that lingers several hours after application. The character which appears several hours after application of the perfume . |
