Sodium hydroxide Usage And Synthesis
descriptionSodium hydroxide, also known as lye and caustic soda, is a highly caustic substance that is used used in small amounts in cosmetics to establish and hold the pH of a product.Sodium Hydroxide is a extremely important compound in our lives because it has so many uses.  It is a very common base used in the chemical industry and is used for many things, many of which occur in our daily lives. One of the most well known uses of Sodium Hydroxide is its use in unclogging drains.  It comes in many different brands of drain cleaners, but one of the most common is Drano.  It also comes in the form of lye soap which can be used to wash practically anything, from the dishes to your face.

At room temperature, sodium hydroxide is a white crystalline odorless solid that absorbs moisture from the air. It is a manufactured substance. Sodium Hydroxide is an inorganic compound used to control the pH levels or serve as a buffering agent in cosmetics and personal care products. It was historically used in the formulation of soaps, but is currently seen in a variety of formulas, including bath products, cleansing products, fragrances, foot powders, hair dyes and colors, makeup, nail products, personal cleanliness products, shampoos, shaving products, depilatories, skin care products, and suntan products, as well as chemical hair straighteners and hair wave sets. It is also a popular ingredient in industrial solvents as a chemical base for soaps, oven cleaners, detergents and drain cleaners because of its ability to dissolve grease, oils, fats and protein based deposits, according to Wikipedia. Less frequently, Sodium Hydroxide is seen as an ingredient in toothpastes.
Sodium Hydroxide is FDA approved, and has received the GRAS (Generally Recognized as Safe) rating as a direct food additive. However, it is primarily used in the washing and chemical peeling of produce. It is approved for use in cosmetics and personal care products in varying concentrations: 5% by weight in nail cuticle solvents, 2% by weight in hair straighteners for general use, 4.5% by weight in hair straighteners for professional use, up to a pH 12.7 in depilatories, and up to pH 11 in other uses as a pH adjuster.
UsesIt is basic chemical raw materials and can be used as high-purity reagents and widely used in chemical, metallurgy, paper, petroleum, textile and household chemicals and other sectors.
It can be used in the production of paper and cellulose pulp; it can also be used in the production of soaps, synthetic fatty acid and the refining of synthetic detergents. In cotton textile industry, it can be used as de-sizing agent, scouring agent and mercerizing agent. In the field of chemical industry, it can be used for the production of borax, sodium cyanide, formic acid, oxalic acid, phenol and the like. In the field of petroleum industry, it can be used to refine petroleum products and applied to the mud drilling in oil field. It can also be used in the production of the surface treatment agent of aluminum oxide, metal zinc and metal copper and glass, enamel, leather, pharmaceuticals, dyes and pesticides. In the fool industry, food-grade product can be used as an acid neutralizer, and can also be used as the peeling agents, bleaching agents, and deodorant of citrus and peaches.
It can be used as analysis reagents, saponification agent, and the absorbent of a small amount of carbon dioxide and as well as used for manufacturing of sodium.
It can be used in textile, printing and dyeing, enamel, paper, synthetic detergents, pesticides, metallurgy, food, rubber and other industries.
It is basic chemical raw material which is widely used in chemical industry, metallurgy, paper, petroleum, textile and household chemicals and other sectors.
For the analysis, it can be used for acid calibration.
It is mainly used for mucus method rayon, synthetic fibers, dyes intermediates, rubber regeneration, fabric dyeing, paper, soap, leather, etc.
It can used as the acid neutralizing agent for being as peeling agent for the processing of fruit but also as the detergent of bottles, cans and other containers. Apply proper amount according to the necessity of the production.

General DescriptionA white solid. Corrosive to metals and tissue. Used in chemical manufacturing, petroleum refining, cleaning compounds, drain cleaners.
Air & Water ReactionsSoluble in water. Dissolution can liberate enough heat to cause steaming and spattering and ignite adjacent combustible material [Haz. Chem. Data 1966].
Reactivity ProfileCAUSTIC SODA (Sodium hydroxide) is a strong base. Reacts rapidly and exothermically with acids, both organic and inorganic. Readily absorbs moisture from the air to give caustic semi-solids that attack aluminum and zinc with the evolution of flammable hydrogen gas. Catalyzes the polymerization of acetaldehyde and other polymerizable compounds; these reactions can occur violently, for example, acrolein polymerizes with extreme violence when put in contact with alkaline materials such as sodium hydroxide [Chem. Safety Data Sheet SD-85 1961]. Reacts with great violence with phosphorus pentaoxide when initiated by local heating [Mellor 8 Supp.3:406 1971]. Contact (as a drying agent) with tetrahydrofuran, which often contains peroxides, may be hazardous---explosions have occurred in such a use of the chemically similar potassium hydroxide [NSC Newsletter Chem. Soc. 1967]. Mixing with any of the following substances in a closed container caused the temperature and pressure to increase: glacial acetic acid, acetic anhydride, acrolein, chlorohydrin, chlorosulfonic acid, ethylene cyanohydrin, glyoxal, hydrochloric acid (36%), hydrofluoric acid (48.7%), nitric acid (70%), oleum, propiolactone, sulfuric acid (96%) [NFPA 1991]. Accidental contact between a caustic cleaning solution (probably containing sodium hydroxide) and Pentol caused a violent explosion. [MCA Case History 363(1964)]. Heating with a mixture of methyl alcohol and trichlorobenzene during an attempted synthesis led to a sudden increase in pressure and an explosion [MCA Guide for Safety Appendix 3 1972]. Hot and/or concentrated NaOH can cause hydroquinone to decompose exothermically at elevated temperature. (NFPA Pub. 491M, 1975, 385)
Health HazardStrong corrosive action on contacted tissues. INHALATION: dust may cause damage to upper respiratory tract and lung itself, producing from mild nose irritation to pneumonitis. INGESTION: severe damage to mucous membranes; severe scar formation or perforation may occur. EYE CONTACT: produces severe damage.
Fire HazardNon-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
