2022-2-1 · Laundry detergents have come a long way since the first bar soaps made from animal fat and lye were offered for sale in the 1700s. The introduction of synthetic detergents to the marketplace in the 1950s offered homemakers more options for fabric care. But it was the 1970s that brought the most significant innovation in the laundry, the addition of enzymes that …
2007-1-30 · An enzyme was first used to improve the effectiveness of a laundry detergent in 1913 by a German named Otto RÖohm, the founder of the giant chemical company Rohm and Hass. The proteolytic enzyme he used, derived from milled animal pancreases, was quite crude and contained many impurities which, in turn, sometimes stained the very textile it ...

Enzyme Analysis. Measuring enzyme activity and enzyme assay is a precise job and can be influenced by many variables. The Gallery Enzyme Master enzyme analyzer is the first fully automated enzyme analyzer designed specifically for enzyme assay applications, from method development to routine analysis to quality assurance/quality control.
Prior to the adoption of improved dust control measures, some factory workers developed allergic respiratory symptoms during the manufacture of enzyme laundry detergents. Since then, the industrial hygiene problem is being brought under control by maintaining dust exposure below levels where allergic respiratory symptoms develop. However, the fact that enzyme allergies …
We present a practical activity focusing on two main goals: to give learners the opportunity to experience how the scientific method works and to increase their knowledge about enzymes in everyday situations. The exercise consists of determining the amylase activity of commercial detergents. The methodology is based on a qualitative assay using a colorimetric process.
2005-6-1 · Further, detergents with structures like fatty acids (such as Triton X-100) can inhibit lipases (Gilham and Lehner, unpublished results and ), or may be hydrolyzed by the lipase (such as Tween 20) resulting in competition with the intended substrate, etc. Strong detergent may also denature the enzyme, resulting in loss of activity.
