- The origins of soap are unknown, likely invented independently in various places before recorded history.
- Soap is created through saponification, mixing fats (animal or vegetable), alkali (from ash), and water.
- Early soap may have been discovered accidentally, possibly from cooking fats mixing with ash and water.
- The first recorded evidence of soap-like materials dates back to 2800 BC in Ancient Babylon, used for garment washing.
- Gallic (Celtic) soap, mentioned by Pliny the Elder (AD 77), was used for hair dyeing and later for hygiene.
- Aretaeus of Cappadocia (2nd century AD) documented the first clear evidence of soap used for personal hygiene by Gauls.
- By the 6th century, Gallic soap was well-known in the Byzantine Empire, often enhanced with fragrances.
- Olive oil-based soap emerged in the Middle East and Mediterranean, becoming a luxury product.
- Industrial advancements in the 18th–19th centuries made soap affordable and widely available.
- Modern soap production was revolutionized by chemists like Nicolas Leblanc and Ernest Solvay.
