Glycol DPM is able to be used for a wide variety of applications. 
Dipropylene glycol monomethyl ether is useful on both a household and industrial level and is often used as a solvent or a coupling agent. 
Glycol DPM is useful in:
-Grease and paint removers
-Metal cleaners
-Hard surface cleaners
-Tail solvent for solvent-based printing ink
-Primary solvent for silk-based printing ink
-Stabilizer for agricultural herbicides
-Coalescent in floor polishes and finishes.

Dipropylene Glycol Monomethyl Ether is a colorless and transparent liquid. 
Dipropylene glycol monomethyl ether can be used as a solvent in water-based paints and screen-printing inks. 
Dipropylene glycol monomethyl ether can also be used as the coupling agent (often mix) of dilute aqueous coatings.

Dipropylene glycol monomethyl ether SWALLOWED
-Accidental ingestion of the material may be damaging to the health of the individual.
-Central nervous system (CNS) depression may include general discomfort, symptoms of giddiness, headache, dizziness, nausea, anaesthetic effects, slowed reaction time, slurred speech and may progress to unconsciousness.
Serious poisonings may result in respiratory depression and may be fatal.
Lethal doses produced respiratory failure within 48 hours.

EYE
-Limited evidence or practical experience suggests, that the material may cause eye irritation in a substantial number of individuals.
Prolonged eye contact may cause inflammation characterized by a temporary redness of the conjunctiva (similar to windburn).
-When one drop of undiluted dipropylene glycol monomethyl ether (DPME) was placed in a rabbits eyes on each of five consecutive days, a mild transitory irritation of the conjunctival membranes occurred. 
Fluorescein staining revealed no corneal damage.

SKIN
-Skin contact with the material may damage the health of the individual; systemic effects may result following
-There is some evidence to suggest that the material may cause mild but significant inflammation of the skin either following direct contact or after a delay of some time.
Repeated exposure can cause contact dermatitis which is characterized by redness, swelling and blistering.
-Open cuts, abraded or irritated skin should not be exposed to this material.
-Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects.
Examine the skin prior to the use of the material and ensure that any external damage is suitably protected.
-Continuous contact with DPME of the skin of numerous rabbits for 90 days caused only slight scaliness.
Patch tests on human volunteers produced no evidence of primary irritation or sensitisation.

INHALED
-Dipropylene glycol monomethyl ether can cause respiratory irritation in some persons.
The body's response to such irritation can cause further lung damage.
-Inhalation of vapours may cause drowsiness and dizziness.
Dipropylene glycol monomethyl ether may be accompanied by narcosis, reduced alertness, loss of reflexes, lack of coordination and vertigo.
-Inhalation hazard is increased at higher temperatures.
-Not normally a hazard due to non-volatile nature of product.
-In fog-laden atmospheres rats exposed to dipropylene glycol monomethyl ether DPME, for 7 hours, exhibited a mild narcosis from which they rapidly recovered.
Controlled human exposures to vapour produced CNS impairment at 1000 ppm in one subject.
-Acute effects from inhalation of high vapor concentrations may be chest and nasal irritation with coughing, sneezing, headache and even nausea.

CHRONIC HEALTH EFFECTS
-Long-term exposure to respiratory irritants may result in disease of the airways involving difficult breathing and related systemic problems.
Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems.
Some glycol esters and their ethers cause wasting of the testicles, reproductive changes, infertility and changes to kidney function. 
Shorter chain compounds are more dangerous.
