[28] 1,4-Dioxane was present in ethoxylated raw ingredients at levels up to 1410 ppm (~0.14%wt), and at levels up to 279 ppm (~0.03%wt) in off the shelf cosmetic products. [28] Levels of 1,4-dioxane exceeding 85 ppm (~0.01%wt) in children's shampoos indicate that close monitoring of raw materials and finished products is warranted. [28] While ...

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
People wonder about the health risks they face – from driving on Interstate 4, to sun exposure, to consuming alcohol, to eating bacon and more – but drinking tap water usually isn’t one of them.
The Haw River empties into the southern end of Jordan Lake. Apex and Cary draw their drinking water about six miles northeast, near U.S. 64.
Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure.
Sanford is calling on two state agencies to say what they know regarding the 1,4-dioxane contamination first discovered a decade ago in the city’s wells, including at what concentration and over ...
