Thanks for your enquiry, maybe you have already seen the work from the US Environmental Agency. There is a large document, not very new about new technologies, they explain about 'Liquid Carbon Dioxide', 'Ultrasonic Cleaning Process, Rynex Solvent, Biotex Solvent'.
"Chemical solvents have been used for cleaning clothes since the mid-19th century. Perchloroethylene (PCE) has been the solvent of choice for commercial clothes cleaning applications since the 1960s, although the volume used by drycleaners has declined significantly over the last decade. Despite this decline, a variety of health and safety issues associated with PCE use and increased regulation of the chemical have compelled the U.S. Environmental Protection Agency (USEPA), industry and environmental groups to address concerns about PCE emissions. As part of an effort to explore opportunities for pollution prevention and reduce exposure to traditional drycleaning chemicals, the EPA’s Design for the Environment (DfE) Garment and Textile Care Program has developed the Cleaner Technologies Substitutes Assessment (CTSA): Professional Fabricare Processes."
The document tries to evaluate the tradeoff between efficiency and risks to health and environment. You can find the document at:

WARNING: it's 450 pages long! A.]
About the two products that you mentioned, they have also been studied widely and peer reviewed.
You can find the large studies from the US Enviromental Agency for Aquatex at:

and for Ecoclean at:

I am not sure that any of these products is completely safe to use as they all contain large amounts of chemicals [
Doesn't everything?? A.]. Ecover detergents and some dry-cleaners that are advertised as organic (
