A chemical mixture used to preserve the tissue structures of an animal for histological study. Common fixatives used for C. elegans include aldehydes which fix protein, osmium tetroxide which fixes and stains lipids, and methanol/acetic acid which both fixes and clears tissue.
( in aromatherapy ) counters volatility of certain perfume components
a compound (such as ethanol or formaldehyde) that fixes tissues and cells for microscopic study
a plant or animal substance of low volatility that serves to draw together and hold the fragrances of other materials
a substance that combines well with the other ingredients in a blend, slowing down the evaporation of the fragrance and making it last longer when applied as a personal essence
Acts to slow down the evaporation rate of other essential oils.
a material which slows down the rate of evaporation of the more volatile components in a perfume composition.
a substance added to a perfume esepecially to prevent rapid evaporation.
Holds the scent of a fragrance.
An oil that is able to slow the evaporation of the more volatile oils. Fixative oils are usually base notes in a blend and perform the valuable function of creating a longer lasting, harmonious aroma.
A material which slows down the rate of evaporation of the more volatile components in perfume comosition and natural product formulation.
A substance which slows down the rate of evaporation of the more volatile components in a perfume combination.
Used to anchor or stabilize a scent or fragrance, to slow evaporation.
A viscous (thick) oil with a very low evaporation rate; used in perfumery to stabilize and increase the 'staying power' of a blend.
(AKA fixed oil) In perfumery, a material that slows down the rate of evaporation of the more volatile materials in a perfume composition. So-called vegetable oils fall into this category.
A fixative is a chemical which renders a cell or organism suspended or preserved in a stable state, usually so that it can be studied at a later date. For instance, a fixative might be used to preserve a tiny organism on a microscope slide.
A substance added to a perfume to slow the rate of evaporation.
Material that slows down the evaporation rate of more volatile components in a perfume composition.
is a perfume ingredient which prolongs the retention of fragrance on the skin and makes other fragrant ingredients mixed with it last longer.
A material used in a perfume to 'fix' the perfume or make it last longer. Fixatives may be simply materials that are relatively longer lasting than the other components in the perfume or they may have some physical or chemical effect of forming bonds with the other materials.
slows evaporation rate of volatile compounds in perfume
1. A substance that makes something permanent. 2. An element that prevents fading or evaporation. 3. Something that increases durability. Fixed Permanent. Unmovable.
A material that "fixes" the scent and slows evaporation of the essential oils
A fixative is an ingredient added to perfume to make it last longer, similar to a preservative.
A fixative is a stabilizing or preservative agent.
In perfumery, a fixative is a natural or synthetic substance used to reduce the evaporation rate and improve stability when added to more volatile components. This allows the final product to last longer while keeping its original fragrance. Fixatives are indispensable commodities to the perfume industry.
