The words "Macassar Oil" were registered as a Trademark by A. Rowland & Sons, of London, in 1888 (#15,093). The label shown was included as an example of how the Trademark was used. George W. Rowland was one of those who signed the petition. He indicated that the Trademark had been in use since 1797. According to Fike, this product was introduced by Alexander Rowland in 1793. There is a fantastic treatise on the hair by Alexander Rowland dated 1814. It is available on Google Books
According to Fike, Rowland's Macassar Oil was still for sale in 1953. An ad in the 1865 English Woman's Domestic Magazine listed four sizes of the bottles.
