C

CAS Registry Number

A unique numerical identifier assigned by the Chemical Abstracts Service (CAS) to every chemical substance described in the open scientific literature.

E

A substance that stabilizes an emulsion, which is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable), like oil and water. They work by reducing the surface tension between the two liquids.

S

Saponification Value

A measure of the average molecular weight (or chain length) of all the fatty acids present. It is expressed as the number of milligrams of potassium hydroxide (KOH) required to saponify one gram of fat under the conditions specified.

Surfactant

Short for "surface-active agent," surfactants are compounds that lower the surface tension between two liquids, between a gas and a liquid, or between a liquid and a solid.
