Nalgene

== Description ==
[ThermoFisher, formerly Nalge Nunc] A registered trademark for a series of plastic containers made from polypropylene, polyethylene, Teflon®, Silicone, Acrylic, polystyrene, and polycarbonate. Originally sold for laboratory use, most of these containers are relatively inert to chemicals and solvents. At the end of the 20th century, Nalgene® introduced a line of consumer products, including the popular sports' water bottles that were advertised as indestructable.

Naphtha

== Description ==
Since ancient times, the word 'naphtha' has had many meanings. Originally, it was a Persian word for liquid bitumen or petroleum. Later, naphtha refered to the volatile and flammable components in petroleum. Currently, it is used by the petroleum industry to refer to the petroleum or coal-tar distillate fraction obtained over the same boiling range as gasoline (35-204C). Naphtha contains both aliphatic and aromatic hydrocarbons. Naphtha is also used as the common name given to smaller portions of this hydrocarbon distillate mixture. 
* Light naphtha or petroleum ether = fraction collected from 35-60C 
* Petroleum naphtha, ligroin, or VM&P naphtha = fraction collected from 90-150C 
* Heavy naphtha, or mineral spirits = fraction collected from 150-200C 
Naphtha is used as a solvent and dry-cleaning fluid to remove oil and grease.
== Risks ==
* Highly flammable (flash point = -18C). 
* Toxic by ingestion and inhalation. 
* Univar Solutions: SDS
== Synonyms and Related Terms ==

Naphthalene

== Description ==
White, crystalline flakes with a strong mothball odor. Naphthalene is derived from coal tar. It consists of two aromatic rings attached on one side. Naphthalene was formerly used as a dusting powder, insecticide, fungicide, and moth repellent. It is not recommended for general use as an insecticide because it may recrystallize on specimens and can discolor wool in the presence of moisture. Additionally, its actual effectiveness against insects is questionable. It is used industrially as an intermediate in making dyes, explosives, and synthetic resins. Naphthalene can sublime at room temperature.

==Risks ==
* Toxic by ingestion, inhalation and skin absorption. 
* May cause allergic reactions. 
* Natural resins are softened by naphthalene. 
* Can corrode metals. 
* Combustible. Flash point = 87C (189F)

Naphthol pigment

== Description ==
A general class of azo-type organic colorants. Naphthol pigments contain a backbone of 2-hydroxy-3-naphthanilide (Napthol AS) and include many shades of red and some oranges. They were first patented in 1911 and sold as Grela Reds but did not become popularly used until the 1930s. About 6% of the red colorants used in 1985 were naphthol pigments. They provide good tinting strength and good lightfastness, but can bleed when exposed to organic solvents. Naphthol reds are used to color plastics, automotive finishes, architectural paints, pencils, crayon, printing inks and inexpensive artists oil paints and watercolors.

| This color is what was called as "Narashiba ()" in the Hitachinokuni-fudoki (), from 721 AD, Japan. With the left sample, the dyeing procedure was: 1) dye bath; 2) mordant bath; and 3) ash water bath. The resultant color on the right sample was similar to those dyed with acorns.
