May 16, 2010·One solution that the washing powder manufacturers have come up with is to add enzymes to the powder. Enzymes are biological catalysts, molecules assist chemical reactions and make them occur much faster and more easily without being used up themselves. Each enzyme molecule can catalyze thousands of reactions.

Biological washing powders contain enzymes which …

Biosciences - Enzymes - SAASTA

The biological powder is supposed to contain an enzyme which 'removes difficult stains like egg, gravy and blood'. These contain proteins. If this is a true claim, we would expect to find the gelatine (a protein) dissolved away under the 'biological' washing powder, but not under the ordinary powder.

Which laundry enzymes work best? | www.scienceinschool.org

If small amounts of biological detergent remain on clothing, however, they can irritate sensitive skin. For this reason, the use of non-biological detergent is preferred in some situations, particularly for washing clothes for babies. For tackling tough stains, however, non-biological detergents often need to be used at a higher temperature.

Investigating enzymes used in laundry detergents

Enzymes used in food processing are generally destroyed during subsequent processing steps and not present in the final food product. When enzymes are used to remove stains from fabrics, clothes can be washed at lower temperatures, thus saving energy. Enzymes provide an alternative to chlorine bleach for removing some stains from cloth.

GCSE CHEMISTRY - Which Enzymes are used in Biological ...

Rates of Reaction. Catalysts - Enzymes - Biological Detergents.. Which Enzymes are used in Biological Detergents?. Biological detergents and washing powders use lipases and proteases to break down fat and protein molecules from food stains that have remained on clothing. The fatty acids, glycerol and amino acids that are produced are removed in the water during the washing process.

Measuring the action of washing product proteases

original patent, enzyme washing powders began to take off. Today enzymatic detergents occupy 85% of the washing powder market in Western Europe and 50% of the market worldwide. Biological washing powders account for almost a quarter of the enzymes sold throughout the world. Most European consumers regard enzymes as

Enzymes and their uses

Enzymes can be taken out of organisms, purified and then used in science and industry. One common use in the home is in biological washing powders. These contain amylase, lipases and proteases and break down any stains that contain carbohydrate, fat and protein.
