Borwick’s was the highest selling baking powder in the world.
George Borwick (1807 – 1889) was born in Cartmel, Lancashire. He worked as a teacher in West Bromwich and married Jane Hudson (1807 – 1868), the daughter of a Congregationalist minister, in 1831.
Borwick’s brother in law, Robert Spear Hudson (1812 – 1884), had introduced the first successful commercial soap powder in 1837. A trained chemist, Hudson gifted his baking powder formula to Borwick.
Borwick relocated to 18 Aldermanbury, London to work as a wholesale agent selling Hudson’s washing and bleaching powder as well as his new baking powder, from 1844.
“Borwick’s German Baking Powder” received a recommendation from the private baker to Queen Victoria in 1849.
The firm traded as Borwick & Priestley, wholesale druggists and drysalters of 24 and 25 London Wall, London, between 1850 and 1852.
Borwick also introduced a successful egg powder.
Dr Hassall (1817 – 1894) analysed Borwick’s baking powder in 1855 and found it to consist of tartaric acid, soda (or maybe potassium carbonate), ground rice, a small amount of wheat flour and possibly a little sugar.
Borwick’s returns averaged £12,000 to £14,000 a year between 1845 and 1857.
Borwick’s baking powder and egg powder became some of the first widely known consumer products in Britain.
George Borwick employed 75 men and boys and 8 girls in 1861.
Growing sales saw premises relocated to 24 Chiswell Street, Finsbury from 1864.
Robert Hudson Borwick (1845 – 1936) and Joseph Cooksey Borwick (1847 – 1913), sons of George Borwick, entered the business in 1865 after a brief period working as manufacturing confectioners. They were made partners by 1870, and the firm traded as George Borwick & Sons.
George Borwick & Sons was awarded a Royal Warrant for baking powder from the Queen of the Netherlands in 1870.
Borwick’s baking powder won its fifth gold medal at an International Exhibition in 1882.
