Second, the recycled HDPE can be used in a multilayer structure which provides a layer of virgin polymer as the product contact phase. This approach was first used for laundry products when problems were encountered with migration of odorous substances from recycled... 

Cleaners containing oxygen bleach or peroxides are gaining in popularity. Contrary to the usual trend in developed nations, these products are often in powder form rather than liquid to facilitate delivery of the peroxide (usually in the form of percarbonate), which is very difficult to stabilize in liquid formulation [44]. They are usually aimed at laundry problems, but directions on the label give dilution instructions for use as a cleaner on a variety of hard surfaces as well. Surfactants used in these cleaners are usually anionic or nonionic at low concentrations (<5%). Oxygen bleach formulas are touted for their greater surface safety, but with the greater safety comes a decreased spectrum of stains that can be bleached. 

The greatest field of application for nickel is austenitic stainless steels. This steel type and the influence of nickel are dealt with in Chapter 24 Chromium. Stainless-steel production accounted for more than 60% of the world nickel demand in the year 2000. The chemical industry is a very big consumer of nickel for a multitude of applications, mainly in stainless steels. In our everyday life we also meet nickel-containing, austenitic stainless steels in kitchen sinks, laundry equipment and cutlery, in railway cars and tank trailers. For the oil rigs offshore, with their exceptional corrosion problems, special stainless steels with high molybdenum contents, have been developed.
