Benzyl alcohol is an aromatic alcohol with the formula C6H5CH2OH. The benzyl group is often abbreviated "Bn" (not to be confused with "Bz" which is used for benzoyl), thus benzyl alcohol is denoted as BnOH. Benzyl alcohol is a colorless liquid with a mild pleasant aromatic odor. It is a useful solvent due to its polarity, low toxicity, and low vapor pressure. Benzyl alcohol has moderate solubility in water (4 g/100 mL) and is miscible in alcohols and diethyl ether. The anion produced by deprotonation of the alcohol group is known as benzylate or benzyloxide.

Sodium thiosulfate (sodium thiosulphate) is an inorganic compound with the formula Na2S2O3.xH2O. Typically it is available as the white or colorless pentahydrate, Na2S2O3·5H2O. The solid is an efflorescent (loses water readily) crystalline substance that dissolves well in water. It is also often called sodium hyposulfite or hypo.

Sodium diacetate is a compound with formula NaH(C2H3O2)2. It is a salt of acetic acid. It is a colorless solid that is used in seasonings and as an antimicrobial agent.Sodium acetate is produced by reaction of acetic acid with sodium hydroxide. When acetic acid and sodium acetate are mixed in equimolar proportions and allowed to crystallize, the sodium acetate crystallizes with acetic acid of crystallization. This material is called sodium diacetate (E262). It provides a solid source of acetic acid for use in dry products.
