C

Cabannes Factor

A factor used in light-scattering analysis to correct for particle anisotropy. See Depolarization.

Calcination

Producing, or modifying, a powder material by heating it to a high temperature in a dry atmosphere.

Calculation of Phase Inversion in Concentrated Emulsions

(CAPICO) A system in which potential cosmetic emulsion ingredients are numerically categorized so that one may calculate their influence on the phase inversion temperature of a formulated emulsion. See Reference [91].

Canada Balsam

An optical adhesive comprising the resin of balsam fir trees dissolved in a solvent. It is used in microscopy to permanently fix a specimen for viewing under a cover slide (slip) on a glass slide. As its refractive index is close to that of crown glass, the specimen remains clearly visible. It has been similarly used in the preparation of thin sections for mineralogical study. Canada Balsam has also been used as a glue in the manufacture of lens elements and prisms for the same reason. The use of Canada Balsam has mostly been supplanted by modern synthetic adhesives. Synonyms include Balsam of Fir and Canada Turpentine.

Canada Turpentine

See Canada Balsam.

Canal Viscometer

An instrument used to measure interfacial viscosity by measuring the flow rate of a surface or interfacial layer through a narrow channel or canal. The analysis is essentially a two-dimensional analog of the capillary viscosity method for fluids.
