adulterant

The roots of this, after being ground and roasted, are used either as a substitute or an adulterant of coffee.

The root of this plant is the common adulterant of coffee, and large quantities are used for this purpose.

Otherwise, as likely as not, oil of geraniums is substituted for the attar of roses, or is used as an adulterant.

Strictly, therefore, this substance is not an adulterant, inasmuch as it is not a substitute in any sense for flour.

If the ratio falls below 3.6, stearic acid or resin has been used as the adulterant.
