 | | As the balsam solidifies, its odour becomes more feeble, but the quantity of cinnamic acid increases, and it thus becomes valuable to perfumers as a fixative, an ounce added to a pound of volatile perfume making it much more permanent. |
 | | Tolu Balsam is frequently adulterated with turpentines, styrax, colophony, etc., and may be tested by heating it in sulphuric acid. |
 | | It is freely soluble in chloroform, glacial acetic acid, acetone, ether, alcohol and liquor potassa, scarcely soluble in petroleum-benzine and benzol. |
