Who discovered detergent? The use of enzymes to clean laundry, and hence the invention of laundry detergent, was introduced in the early 20th century by Otto Rohm. Mr. Rohm founded Röhm & Haas in Germany in 1907, and his research on using enzymes in technical applications became a revolution in the use of washing detergents in 1914.
Also, Where was Tide detergent invented?

What is the history of detergent? During World War I and again in World War II, there was a shortage of animal and vegetable fats and oils that were used in making soap.

How did soap originate?
Ancient Mesopotamians were first to produce a kind of soap by cooking fatty acids – like the fat rendered from a slaughtered cow, sheep or goat – together with water and an alkaline like lye, a caustic substance derived from wood ashes. The result was a greasy and smelly goop that lifted away dirt.
What is the characteristic of detergent?

What is the characteristics of laundry detergent?
Detergents are surfactants since they can decrease the surface tension of water. Their dual nature facilitates the mixture of hydrophobic compounds (like oil and grease) with water. Because air is not hydrophilic, detergents are also foaming agents to varying degrees.
What are the two types of detergents?
Types of Laundry Detergents
- Anionic Detergents.
- Cationic Detergents.
- Non-ionic Detergents.
- Amphoteric or Zwitterionic Detergents.
- A mixture of Anionic and Non-Anionic Classes.
Is detergent an acid or base?
When chemicals are dissolved in water, the mixture’s pH level can become either acidic or basic (alkaline). Vinegar and lemon juice are acidic substances, while laundry detergent and ammonia are basic. With a pH level of 7.0, pure water is neutral.
Why is it called soap?

How do detergents work chemistry?
How do detergents work? Soaps and detergents are made from long molecules that contain a head and tail. These molecules are called surfactants; the diagram below represents a surfactant molecule. The head of the molecule is attracted to water (hydrophilic) and the tail is attracted to grease and dirt (hydrophobic).
