Question:

Are ink and additives used in inkjet printers harmful to humans?

I have been working on the code for two years, would like to ask, this ink, additives, cleaning agents on what harm people, how long this work can be done (ink, additives, cleaning agents above the environmental labeling)

Answer:

Invasive approach: inhalation, ingestion, percutaneous absorption.
There are ah, the solvent that things are caused by how the chemical will not harm
The chemical properties of butanone and acetone are very similar. Butanone: colorless liquid. A melting point of -86.3 ° C, a boiling point of 79.6 ° C and a relative density of 0.8054 (20/4 ° C). Dissolved in about 4 times the water, soluble in ethanol, ether and other organic solvents. And water to form a constant boiling point mixture (containing butanone 88.7%), the boiling point of 73.4 ℃. Steam and air to form an explosive mixture, the explosion limit of 2.0% to 12.0% (volume). The chemical properties are similar to acetone.
The main ingredients used in the ink and thinner are: butanone (also known as methyl ethyl ketone) or acetone, there are a small amount of alcohol.
