Modern detergents contain as many as eight different enzymes. In 2016, Novozymes generated about $2.2 billion in revenue and provided enzymes for detergents including Tide, Ariel and Seventh Generation.
The quantity of enzymes required in a detergent is relatively small compared with chemical alternatives, an appealing quality for customers looking for more natural ingredients. A tenth of a teaspoon of enzymes in a typical European laundry load cuts by half the amount of soap from petrochemicals or palm oil in a detergent.
Enzymes are also well suited to helping cut energy consumption. They are often found in relatively cool environments, like forests and oceans. As a result of that low natural temperature, they do not require the heat and pressure typically used in washing machines and other laundry processes.
