Adhesives used in mattresses are Toxic
Adhesives in mattresses are used to stick mattress components together and they
emit
toxic fumes for the first 2-3 years.
Harmful effects of adhesives
If you have bought a new mattress, you may be sleeping on a bed of harmful chemicals
and inhaling the toxic fumes emitted by the adhesives used in mattresses. You
would be surprised to know that while sleeping you are inches away from glues,
inhaling unhealthy fumes for
8 hours per night for
365
days per year.
EPA (Environmental Protection Agency) observes that the adhesives used in
mattresses may irritate the skin and the eye if you come in contact with it.
Irritation is your body responding to a contaminated environment.
Potential human health effects of adhesives can be classified broadly into:
- Cancers
- Systemic toxicity
- Developmental toxicity

list of toxic components
found in mattresses.
Cancers
According to EPA, many ingredients used in adhesives are
proven carcinogens,
that is, they cause cancer on chronic exposure. These chemicals can
disrupt
normal growth and body development as well as instigate the cells for
abnormal growth which
results in cancer.
EPA identifies
methylene chloride as a potential carcinogen.
Also,
benzene and
formaldehyde are examples
of carcinogenic compounds used in many adhesives.
Systemic toxicity
Many adhesives use solvents that are known for interfering with the proper functioning
of our body. Hexane, a solvent in adhesives is a
neurotoxin
and causes peripheral neuropathy, EPA identifies. Similarly, toluene is also
a neurotoxin shown to cause
damage to central nervous system.
In addition to the nervous system, all other body systems are equally at risk.
Developmental toxicity
If you are an
expectant mother, there are chances your unborn
baby gets affected by harmful adhesives used in mattresses.
EPA identifies n-Propyl bromide results in developmental toxicity. Xylene, an
ingredient used in glues causes
birth defects.
A mattress may be comfortable but nobody wants to bargain with their health.
The ideal would be a zero-emission mattress that does not contain harmful
adhesives.
The ideal would be a zero-emission mattress free of any adhesives and other
toxins.
Types of glues
The type and quality of the glue is an important factor in deciding the durability
of standard mattresses.
The glues used in the mattress industry are of mainly seven following types:
1. Methylene chloride-based adhesives
2. n-Propyl bromide-based adhesives
3. Acetone-based adhesives
4. Adhesives based on acetone blends with other chemicals
5. Water-based latex adhesives
6. Water-based latex/synthetic adhesives
7. Hot melt adhesives
Ingredients in adhesives
In any kind of adhesive, the main ingredients are:
- Solvent/water carrier
- Solid component
- Antioxidant
- Surfactant
- Stabilizers
- Fillers
Solvent or water carrier
It is the main ingredient in solvent and water-based adhesive formulations.
The function of these formulations is to dissolve the solids ingredients that
are deposited while bonding two surfaces. All types of adhesives have solvent
content except for hot melt adhesives which are 100-percent solid content and
rely on heat to cure.
Solid component
The solid component is responsible for the bonding of two surfaces. It is usually
dissolved in the solvent and is deposited on the surface when the solvent evaporates.
Most of the adhesives use a polymer called as styrene-butadiene-styrene block
copolymer, as the solid component; except for the water-based adhesives that
use latex.
Tackifying resin
Tackifying agents gives a sticky nature to the adhesives. The agent makes both
surfaces in contact to “tack up”. Most of the adhesives use a rosin-based
material as tackifying agent.
Antioxidants
Antioxidants are an important ingredient in mattresses adhesives because they
protect the glue for getting oxidized in their containers. Antioxidants account
for 0.1 to 1% of the total volume.
Surfactant
Surfactant is an important component of water-based adhesives constituting 0.5
percent of the glue. Surface-active agents are chemicals that increase the emulsifying,
foaming, dispersing, spreading and wetting properties of a product.
Stabilizers
Some adhesives are unstable chemically or thermally, and need addition of stabilizers
to function well. Some stabilizers neutralize acids and bases formed in the
glue due to interaction between the ingredients.
Fillers
Some adhesives used in mattresses use fillers. Filers are high-molecular-weight
substances like wax used for strength.
