Introduction
I work as a lab technician in a cosmetics company's research
and development department. Nail varnish remover is one of
the company's offerings. Ethyl ethanoate is used in the nail
polish. I am looking at how to make ethyl ethanoate and how to
measure its purity so that the company can manufacture it
effectively. I am going to make an ethyl ethanoate sample to
measure its purity. I will have to equate my laboratory methods
to the cosmetics company's manufacturing method for
producing ethyl ethanoate on a wide scale.
Ethyl ethanoate
Ethyl ethanoate is one of the most widely used small esters. It
is a flammable, colourless liquid with a sweet odour that is used
in perfumes, flavourings, and pharmaceuticals. Ethyl ethanoate
is a common ingredient in nail polish removers and lacquer
thinners since it serves as an organic solvent. Because of its
low boiling point, it has evaporative properties and can be used
in plasticisers and glues. Polystyrene cement, for example, is
made up of polystyrene soaked in ethyl ethanoate.
, Risk assessment
Ethyl ethanoate is an irritant that can cause irritation if it
encounters the eyes or skin. You can also feel lightheaded and
dizzy because of the exposure. Wearing medical masks and
gloves, as well as properly treating ethyl ethanoate, are all
precautions to take. You can also feel lightheaded and dizzy
because of the exposure. Wearing medical masks and gloves,
as well as properly handling ethyl ethanoate, are all
precautions to take.
Glassware – since it is sharp, broken glassware can inflict
wounds. The office may also be disrupted by broken glassware
because tiny pieces of glass can go unnoticed. Handling
glassware properly to avoid breakage is one safety/control
mechanism to avoid this danger. Furthermore, if the glassware
cracks, wipe up the glass pieces as soon as possible and wear
protective glasses.
