Don't mix! (Do you know any cleaning agent that is dangerous to mix?)

　We live a clean and comfortable life in our daily lives using many household chemical products such as spray products, paints, cleaning agents, etc. However, some chemical products contain "toxic substances."
　In addition, these chemical products may cause unexpected health hazards if used incorrectly. In order for us to live safely, we need to use chemical products well.

（1） Do you know that there are various types of household cleaning agents, such as acidity, neutrality, and alkaline?

Type of household cleaning agent
	Type	pH	Chemical Substances
1	Acid type	PH 3 or less	There are inorganic acids such as hydrochloric acid and sulfuric acids as the main components, and organic acids such as sulfamic acid and oxuric acid. In some cases, surfactants are added to these.
2	Mild acidic type	pH3～6	Some are mainly composed of ion and non-ion surfactants.
3	Neutral type	pH6～8
4	Weak alkaline type	pH8～11
5	Alkaline type	PH 11 or higher	Some are mainly composed of sodium hydroxide, potassium hydroxide, etc., and some are obtained by adding surfactants and sodium hypochlorite.

（2） Do you know the action of the main ingredient of household cleaning agents?

The action of the main component of household cleaning agents
	Name of chemicals	Action of Chemical Substances
1	Hydrochloric acid, sulfuric acid (inorganic acids)	It mainly decomposes inorganic substances (calcium phosphate, etc.) to remove dirt.
2	Sodium hydroxide, potassium hydroxide	It mainly decomposes organic substances such as oil to remove dirt.
3	Surfactants	It works against dirt, emulsification, dispersion, etc. to remove dirt.
4	Sodium hypochlorite	Mainly bleach and decompose organic matter to remove dirt.

（3） Do you know that there is a danger or a mixed danger when using an acidic type washing agent and alkali type washing agent containing hypochlorite or alkaline type washing agent?

　Mixing these detergents is dangerous because chlorine gas is generated.
　It is known that this chlorine gas was first used by the German army (1915) as a poison gas in World War I.
　The odor of this chlorine gas can be found even if it is about 4 ppm in the air. It is also a strong irritating yellow gas that coughs at about 30 ppm.
