Lipases are a type of enzyme that can be used to target and break down fats. We use these in some of our products to improve cleaning performance and efficiency.

Enzymes are a kind of protein that occur naturally in the body, but have also been engineered for use in commercial cleaning products for many decades. The enzymes we use are produced in microbial systems, and they work by speeding up chemical reactions. When used in cleaning products, they can help dissolve stains attached to clothes or dishes by converting them into substances that are more easily removed in the cleaning process. Lipases specifically help to break down fats so they're water-soluble, improving stain removal.

Regarding their safety profile, extensive testing in large scale human studies has shown no evidence of the ability of enzymes in cleaning products to induce skin sensitisation. The large molecular weight of enzymes suggest they would not be able to penetrate intact skin. Any contact with wash solutions is not linked to significant irritation or allergy and residues on fabrics are so low they are not known to materially contribute to any skin effects. The combined evidence of substantial research has been sufficient to establish a long history of safe consumer use of enzyme containing products.

Enzymes also have a good environmental profile - they're readily biodegradable and are inactivated to a large extent under washing or cleaning conditions, minimising their impact when they reach the environment. Using enzymes can improve cleaning performance, increasing efficiency and reducing the amount of water and other surfactants required.
