It is limited to those surfactants and detergent systems for which the visible solubility change occurs over a range of 1\u00b0C or less at concentrations of 0.5 to 1.0 % in water between 30 and 95\u00b0C.<\/p>\n<p>1.2 Chemical LimitationsNonionic surfactants that exhibit a characteristic cloud point in general terms consist of a water-in-soluble moiety condensed with 50 to 75 % by weight of ethylene oxide.<\/p>\n<p>1.3 <i>This standard does not purport to address all of the safety concerns, if any, associated with its use.
