So where are we today? We at KRAHN Nordics work with a range of chemical ingredients, all of which find their place in various applications. Even if there is little worry about polyacrylates as such they do persist in nature and its final effects are not fully elucidated. These anionic polymers are mostly derived from acrylic acid and its derivatives, acrylic acid in turn being produced from propylene, a fossil based raw material. As mentioned in the beginning the issues with using phosphates have resulted in its function being replaced by chelating agents in combination with anionic polymers. There is a problem with phosphate performing its job in oceans, rivers and lakes. It will perform its job where it ends up. Phosphate does not recognize when to contribute to biological growth and when not. 2, It performs its crucial task also outside of farming. If we cannot add phosphate into our farming the efficiency of it will be much less. Furthermore it´s access is crucial for modern agriculture. The issues with using phosphate are two: 1, It is an ending resource, once spread into nature it will not “reform” within a reasonable time. So what is the issue with phosphate? Phosphate is a naturally occurring mineral. This means EDTA contributes to animals and humans absorbing heavy metals. EDTA stays and attracts heavy metal ions, which through EDTA is then made available into the food chain. The lack of biodegradation results in EDTA keeping its function, a function well-appreciated in the intended product but dangerous when allowed to persist in nature. Why? When EDTA has performed its function and is subject to outlet in the nature, it finds issues degrading. Furthermore, most people know there is a strive towards replacing EDTA. Most of us know the trend of replacing NTA by EDTA. Looking at the complexing agent part, NTA and EDTA were found to be either toxic or indirectly toxic. At present the drive to abandon fossil-based sources calls for naturally based alcohols instead. The first stage was to replace nonyl phenol (NP) with other synthetic alcohols. The development lead into alternative alcohol bases for these highly efficient components and today the alternatives come in many shapes (around C8-C12 alkyl ethoxylates) with slightly varying properties and efficiencies. Starting with the surfactant base NPE's, which are to a large extent already replaced in the developed countries, they degrade into nonyl phenol which has been found to affect hormone levels in humans and animals. Well, the driver is the (potential) impact on 1, the environment/climate and 2, human health. Today's formulations are highly effective so why do we care about developing new ingredients? Although many detergents for laundry still today contain phosphates, the use of pure complexing agents in combination with anionic polymers are gaining ground by the day. Together with the birth of NTA and EDTA, the former dating back to as early as the mid 1800's, the basic composition of high-performance cleaners started to take shape. The large-scale production of nonyl phenol ethoxylates (NPE's), starting around the 1940's, can more or less be seen as the kick-off for formulation of today's high-performing cleaning agents. Simultaneously.Ever since the start of using soap, dated back as early as 2.800 b.c., there has been a constant development and evolvement of ingredients for formulating cleaning products. And as Eternalism posits, all things that do, have, and will exist do exist. Depending on time and space (space-time, as it's called), "now" is relative. Does this mean if we could somehow instantly shift to a distant star's location, we could experience it's own now "now"? You see the problem. Stars are just too far away for us to perceive except by seeing their past light from distant galaxies takes billions of years to reach us. Of course, we know the latter isn't true simply by looking up at the night sky. Kristie Miller further on ABC News, stands in opposite to "Presentism," the traditional belief that our linear, subjective experience of "now" is the only, single moment that exists. All things that do, have, and will exist do exist in a single, unmoving slab of eternal existence that we only happen to experience moving in one direction: "forward." This notion, explained by Dr. The point is that the Block Universe, or "Eternalism," as its sometimes called, posits that time is an illusion suffered by the mind.
