| This led to hydrogen abstraction from dioxane by curcumin triplet state and the formation of the corresponding ketyl radical. |
|
| After incubation the agarose was washed successively with dioxane solution, dioxane, distilled water and ethanol. |
|
| Carcinogens, such as dioxane and nitrosamine, are commonly formed in synthetic concoctions and are virtually impossible for us to know about. |
|
| In the case of the model compound of tyrosine NAYA, a small bathochromic shift of 2 nm in the emission spectrum from dioxane to water was observed. |
|
| So is dioxane, which rarely appears on labels because it's not an intentionally added ingredient but a byproduct of manufacturing. |
|
| Synergistic Products: Acetone, acetophenone and dioxane appear to increase toxicity. |
|
| White or slightly yellow friable granules or powder, freely soluble in water, soluble in methanol, slightly soluble in alcohol and chloroform, very slightly soluble in acetone and in dioxane. |
|
| Number sign, residual dioxane from Boc deprotection. |
|
| However, Mr. Long said the company has been working for decades to reduce or eliminate even trace elements of 1,4 dioxane and other toxic chemicals in its products and continue to do so. |
|
| And 1,4 dioxane, which has been linked to cancer in animal studies, is created during a process commonly used to make other ingredients gentler on the skin. |
|
| The ability of bacterial consortium to mineralise 1,4 dioxane was studied by the respirometric experiments. |
|
| In a three-necked flask, 120 mmol of paraformaldehyde and 60 mmol of 6-amino-1-hexanol, and 100 mL of dioxane were mixed for about 20 min at room temperature. |
|
| Due to the OH radical's high reactivity, persistent substances such as surfactants or dioxane decompose into carbon dioxide, water molecules and other inorganic compounds. |
|
| Fragrant dioxane derivatives identify 1 subunit-containing GABA receptors. |
|
| Qatar's expert panel which issued the order late on Saturday said the compound 1,4 dioxane was found above 10 parts per million in the two variants of the shampoo brand. |
|
| The likely source of the dioxane is the Twin Cities Army Ammunition Plant, which was identified as the source of other contaminants in New Brighton's drinking water supply. |
