This is demonstrated for the low viscous system 2-butoxy-ethanol/water in Fig. 5. Short time intervals - e.g. 2 sec. - between the measured points result obviously in a stronger variation of the measured cloud points as with longer intervals (e.g. 10 sec in Fig. 5). The phase transition temperature (around 62.6 °C for this mixture) of an isobar can be estimated with an accuracy of 0.5 K.

As more sites are evaluated, the sites at which 2-butoxy ethanol or 2-butoxyethanol acetate are found may increase. This is important because exposure to these substances may harm you and because these sites may be sources of exposure. 

In a study of 2-butoxyethanol acetate, Wistar rats and New Zealand white rabbits were exposed to a saturated vapor-air mixture of approximately 400 ppm 2-butoxyethanol acetate for 4 hours and were then observed for 14 days after exposure (Truhaut et al. 1979). When the animals were sacrificed at the end of 2 weeks, no gross pathological lesions were observed in the hearts of either rats or rabbits. No histological examinations were performed. In the intermediate-duration experiments in this study, in which both gross and histological examinations were performed, no lesions in the heart were noted in either rats or rabbits after intermittent exposure (5 days per week, 4 hours per day) to 400 ppm 2-butoxy-ethanol acetate for 1 month or to 100 ppm 2-butoxyethanol acetate for 10 months (Truhaut et al. 1979). 

No studies were located regarding neurological effects in humans after inhalation exposure to 2-butoxy-ethanol acetate. Male and female volunteers exposed to 98, 113, or 195 ppm 2-butoxyethanol for 4-8 hours experienced headache at 98 ppm and disturbed taste sensation at 113 and 195 ppm (Carpenter etal. 1956). 

No studies were located regarding reproductive effects in humans after inhalation exposure to 2-butoxy-ethanol or 2-butoxyethanol acetate.
