Chemical Name…………………..
CAS#………….

(sodium metasilicate)……..6834-92-0..…….1-4
B.) 2-Butoxyethanol………111-76-2………....1-3
____________________________________________________________________________________________________
As to ingredient "A.)":
A few synonyms:
-Disodium Metasilicate;
-Sodium Silicate;
-Sodium Metasilicate, 9-hydrate;
-Sodium Metasilicate, anhydrous Soluble Glass;
-Waterglass.
Hazardous characteristics:
Corrosiveness:
In moist air it is corrosive to metals such as: zinc, aluminium, tin, and lead...forming hydrogen gas
Reactivity:
The substance is a strong base, it reacts violently with acids.
TOXICOLOGY:
-Sodium metasilicate is markedly corrosive and penetrating.
-Solubilizing reactions occur with protein and collagen, saponifying effects on lipids and dehydration of tissues and cells.
-Sodium metasilicate is highly corrosive due to its buffer capacity, which means that
the high pH is well sustained
in the presence of tissue components that would quickly neutralize other alkalis such as sodium hydroxide
(YIKES!!!)
Eye, ears, nose, throat (local effects):
-Dysphagia, drooling, pain.
-Burns of the epiglottis and vocal cords, and laryngeal obstruction.
-Possible longterm sequelae of acute exposure include esophageal stricture and vocal cord paralysis.
Acute poisoning by:
Ingestion:
-Can cause oral pain, dysphagia, drooling, and pain in the throat, chest, or abdomen.
-Esophageal or gastric perforation may occur, manifested by severe chest or abdominal pain, signs of peritoneal irritation, or pancreatitis.
-Hematemesis and shock may occur.
-Scarring of the esophagus or stomach may result in permanent stricture formation and chronic dysphagia.
Inhalation:-
-Acute exposures involving the inhalation of dusts of sodium metasilicate may result in irritation of the respiratory tract
and corrosive damage may result from contact with mucous membranes.
-Skin exposure usually results in immediate pain and redness. -Serious full thickness burns can occur
Eye contact:
-Eye exposure to corrosive agents commonly results in conjunctivitis and lachrymation. Blindness can occur.
-Sodium metasilicate is used with sodium carbonate in heavy duty alkaline laundry detergents.
This type of detergent causes damage to the cornea, with opacification, proportional to the alkalinity of the preparation.
Other manifestations can include:
-Dysphagia, drooling, pain and hematemesis.
-Oral, oesophageal, and gastric burns may be present.
-Extensive mucosal damage leads to fever, tachypnoea, tachycardia, hypertension, and shock.
-Acute complications include aspiration pneumonia, burns of the epiglottis and vocal cords, and laryngeal obstruction.
-Acute perforation of the esophagus or stomach with mediastinitis or peritonitis, sepsis,
and death may occur.
-Longterm sequelae of acute exposure may include esophageal stricture, squamous cell esophageal cancer, vocal cord paralysis, and pyloric stenosis.
There’s plenty more WARNINGS…But I’ll stop here.
So On To:
Description:
-Sodium metasilicate
is not a cleaning agent, by and of itself.
-It is, however, a VERY strong base.
-In moist air it is corrosive to metals like zinc, aluminium, tin and lead, forming hydrogen gas.
-As a VERY strong base, it reacts violently with acids.
Uses:
-It’s used as a
builder>>>: A material that enhances or maintains the cleaning efficiency of a surfactant…(mainly by “inactivating”
Water hardness)…in soaps and detergents.
-It is used extensively as an anti-corrosion agent in boiler-water feed.
-It may be used as part of a component in a chemical degreaser…where it would react with fatty acids (animal grease)…to form a soap, which is then rinsed away.
The pH:
Even in a 1% aqueous solution….
the pH is ~ 13.
The CANADA WHMIS HAZARD SYMBOL AND CLASSIFICATION:
CLASS D: POISONOUS AND INFECTIOUS MATERIAL
Division 2: Materials Causing Other Toxic EFFECTS
-These materials can cause life-threatening and serious long-term health problems
as well as less severe but immediate reactions in a person who is repeatedly exposed to small amounts.

As to ingredient "B.)": 2-Butoxyethanol
Synonyms:
2-BE, Butoxyethanol, n-Butoxyethanol, 2-Butoxy-1-ethanol, Butyl ethoxol,
O-Butyl ethylene glycol, Butyl glycol, Butyl monoether glycol, EGBE,
Ethylene glycol butyl ether, Ethylene glycol n-butyl ether, Ethylene glycol
monobutyl ether, Ethylene glycol mono-n-butyl ether, Glycol butyl ether,
Glycol monobutyl ether, Monobutyl glycol ether, 3-Oxa-1-heptanol.
2-Butoxyethanol is also known commercially under the following trade names:
Butyl Cellosolve®, Butyl Icinol®, Butyl Oxitol®, Dowanol EB®, Eastman® EB Solvent, Gafcol EB®,
Glycol ether EB®, Jeffersol EB®, Poly-Solv EB®.
Since this is one of the more discussed chemicals…I’ll just list some general information.
Description:
2-Butoxyethanol is an organic solvent.
-It is a colorless liquid with a sweet, ether-like odour.
-It is a relatively nonvolatile, inexpensive solvent with:
"modest surfactant properties", at best.
Uses:
2-butoxyethanol (2-BE) is used in paints and surface coatings,
cleaning products:
(surface cleaner, floor stripper, glass/window cleaner,
carpet cleaner, laundry detergent, rust remover, oven cleaner, ink/resin remover).
-Other products which contain 2-BE include acrylic resin formulations, asphalt
release agents, firefighting foam, leather protectors, oil spill dispersants and photographic strip solutions.
-It is also used as a feedstock in the manufacture of other chemicals, for example, butyl glycol acetate (BGA).
-It's used as a solvent for greases, oils, dyestuffs and nitrocellulose resins and enamels.
-It has been used as an ingredient in agricultural chemicals, cosmetics and brake oils,
-And as a raw material in the production of phthalate and stearate plasticisers.
The principal health effects:
Irritation of the eyes and respiratory tract.
2-Butoxyethanol is readily absorbed through the skin.
-For printing and cleaning operations…There are some concerns and adequate control measures are needed.
-Due to low and intermittent exposure...the public health risk from the use of products containing 2-
butoxyethanol is low. But given the potential for risk to human health in some situations,
further work on the extent of dermalabsorption is ongoing.
2-Butoxyethanol has moderate acute toxicity and is irritating to the eyes and skin; it is not a skin sensitizer.
2-Butoxyethanol is relatively non-volatile, miscible in water, readily biodegradable and non-bioaccumulative.
There is no apparent risk to any of the environmental compartments.
Personally, I see no need for this product in any detailers arsenal.
Used it frequently some years ago at the dealership to degrease transmission fluid leaks on RV's
which generally ran all throughout the frame and rear of travelling motorhome.
May be useful to reconditioners, but not professional detailers...IMO.
This is some dangerous stuff. PPE required...REAL TALK.
^^^I agree…Not something I would recommend for detailing/household use^^^
Trying to tie the two listed hazardous ingredients together…
-One is a binding agent for surfactants…the other is a solvent/”modest surfactant”, at best.
-Is there enough of the listed surfactant (2-BE) to allow the binder (sodium metasilicate) to perform up to par…
OR:
Is there another surfactant/chemicals included that may be proprietary, and not be hazardous…that we should know about?
It just may kill the properties of your defoamer additive...IDK for sure.
I would advise against using in this fashion even though it may be highly diluted.
Will probably attack the backing of carpets and the dye in fabrics.
Mr. Mike Phillips talks about the ever changing landscape of auto-interiors and how a detailer must adjust his skills/chemical-knowledge accordingly.
So...In that vein of thought…
-Even though many, many carpet cleaners contain sodium metasilicate..
It would behoove one, (and be well worth the effort...IMHO), to obtain an auto-carpet cleaner,
(sans sodium metasilicate), that’s been approved by the
CRI:
-Many janitorial supply houses carry such approved products/tools (including steamers/extractors), and provide training at a nominal fee, if so desired.
I used to do quite a bit of hacking before landing at AGO.
I pass on projects rather than harm my rep.
^^^Good Advice^^^
Hope this helps in some form or fashion.
