Documented Uses

• Used in perfumery; as a flavoring agent; in dyes; as a laboratory reagent; in stoving enamels; in cellulose nitrate and acetyl cellulose lacquers; as an additive in paint-removal agents; [HSDB] Used as an un-isolated intermediate in styrene production; as an antimicrobial agent; [CHEMINFO]
• Painting (Solvents) [Category: Paint]
• Painting (Pigments, Binders, and Biocides) [Category: Paint]
• PERFUMERY; FLAVORING; DYES; LABORATORY REAGENT
• Methylbenzyl alcohol can be used like benzyl alcohol, and can be employed in stoving enamels. In cellulose nitrate and acetyl cellulose lacquers, methylbenzyl alcohol helps to improve flow and film formation and prevents blushing at relatively high atmospheric humidity levels. It has also proved to be a useful additive in paint-removal agents on account of its dissolution properties and long evaporation time.
