TiO2 Titanium dioxide has a health safety warning of 1.
It's non carcinogenous but is a mutinagenic for mamallia somatic cells.

It is a skin and eye irritant.

It biodegrades non-toxically. And is not considered an envioromentally hazardous material.

It is used as a white pigment for glues, creams, paint and food colorings.

It can be disposed of in any manner pertaining to the local handling of chemicals due to it's non toxic and stable nature...

Sodium hexametaphosphate • Posted 2 years, 1 month ago. #

1. What is it?
The chemical formula for sodium hexametaphosphate is (NaPO3)n or (NaPO3)*6 or O18-P6.6Na. It is normally in a powder form; white, with no odor.

2. Health Effects:
It can be hazardous to the eyes, harmful when ingested, and slightly hazardous in the case of skin contact and inhalation. Chronic health effects include carcinogenic effects, mutagenic effects, teratogenic effects, and developmental toxicity.

3. Environmental Effects:
All I could find about this topic was that no significant negative effects on the environment will occur when suggested use instructions are followed.

4. Common Uses:
It is used as a food additive. It is sometimes combined with sodium carbonate to raise the pH, which produces products for water softening and detergents.

5. Disposal Procedure:
First, scoop or vacuum, and then place into containers. Proceed to flush the area with water. Dry material may be land filled.

MSDS (Ammonium Lauryl Sulfate) • Posted 2 years, 1 month ago. #

Ammonium Lauryl Sulfate is a chemical that is in the presence of a 12 member carbon chain in the molecular backbone which allows the molecule to bond with non-polar portions of molecules while the highly polar sulfate head allows the molecule to bond with polar molecules such as water.It is commonly used in cleansers because it disrups the relationship of hydrogen bonding with water. It can be an irritant for the eye,skin, and in severe cases cause cancer due to it's carcinogenic properties. Environmentally, all alkyl sulfates are biodegradable and standard wastewater treatment operations removed 96-99.96% of short-chain (12-14 carbons) alkyl sulfates. Even in anaerobic conditions at least 80% of the original volume is biodegraded after 15 days with 90% degradation after 4 weeks. According the HERA project, Ammonium Lauryl Sulfate has little to no impact on our environment.

Monosodium glutamate [MSG] • Posted 2 years, 1 month ago. #

Monosodium glutamate or Glutamic acid is a neurotransmitter that excites our neurons (not just in our tongues). This electrical charging of neurons is what makes foods with added free MSG taste so good.

Fun Fact: At least 25 per cent of the U.S. population reacts to MSG from food sources.

Health Effects:

 Headache
 Flushing
 Sweating
 Facial pressure or tightness
 Numbness, tingling or burning in face, neck and other areas
 Rapid, fluttering heartbeats (heart palpitations)
 Chest pain
 Nausea
 Weakness
 With long term, high dose usage possible neurological damage could occur

Common Uses: Since MSG is cheap and since its neurotoxic nerve stimulation enhances so wonderfully the flavor of basically bland and tasteless foods, such as many low-fat and vegetarian foods, manufacturers are eager to go on using it and do not want the public to realize any of the problems.

There are no environmental effects that I could find and also no special ways to dispose of it.

Phosphoric Acid • Posted 2 years, 1 month ago. #

-Phosphoric acid (H3PO4)
-Hazardous effects: Very hazardous in case of skin contact (corrosive, permeator), eye contact (corrosive) and ingestion. Liquid or spray mist may produce tissue damage particularly on mucous membranes of eyes, mouth and respiratory tract. Skin contact may produce burns. Inhalation of the spray mist may produce severe irritation of respiratory tract, characterized by coughing, choking, or shortness of breath. Severe over-exposure can result in death. Inflammation of the eye is characterized by redness, watering, and itching. Skin inflammation is characterized by itching, scaling, reddening, or, occasionally, blistering.

-Environmental Effects: Can lower oxygen levels in the water, in a process known as eutrophication, which can seriously threaten aquatic organisms.

- Uses: A colorless, odorless, liquid used to acidify colas to give them their tangy flavor, and is also used in fertilizers, pesticides, detergents, and automobile polishers.

-Disposal: If spilled, neutralize the residue with a dilute solution of sodium carbonate and do not touch the spilled material. Call for help for disposal.
