concept of lye

Lye has the chemical name Sodium hydroxide or sodium hydroxide (formulated as NaOH) or commonly known as caustic soda or caustic soda as an inorganic compound of sodium. Sodium hydroxide forms a strong base solution when dissolved in water-like solvents. NaOH solution is greasy, pulp, paper and leather. It is used in many industries such as paper, aluminum smelting, textile dyeing, soap, detergent, artificial silk … The world production in 1998 was about 45 million tons. Sodium hydroxide is also mainly used in laboratories, such as drying gases or reagents.

Application of lye in life

Today we are so popular with lye products because of many uses of this compound such as in cosmetic products, in cooking, water treatment, chemical industries, detergents, …

Application in cosmetic products

lye is used as a pH adjuster in cosmetics The main use of Sodium Hydroxide is to adjust the pH or be used as a filler in cosmetics thanks to the precipitation, the ability to attract water molecules from surroundings, the ability to dissolve grease, fats and proteins. Previously, Sodium Hydroxide was mainly used in soap, but now it is present in almost all formulas for making baths, cleansing products, foot sprays, hair dyes, makeup, nail products. , personal hygiene products, as well as used in hair straightening or curling products.

Use lye to treat water efficiently and economically.

NaOH is basic when dissolved in water, so it has the ability to increase the pH level. In addition, it is also used to neutralize and remove dirt in water supply pipes.
In the wastewater treatment industry, domestic water, sodium hydroxide is a chemical that treats swimming pool water to adjust the pH, bring the pH to the required level, to proceed with the next water treatment steps.

In addition, the addition of caustic soda will help some of the metal hydroxides to form a more durable form and easily precipitate or create glue. On the other hand, with some wastewater containing high levels of COD, the use of NaOH to increase the pH will make the microbiological water treatment more convenient. Specifically, when the pH level increases to the required level, this is a favorable environment for microorganisms to multiply and grow. At that time, the treatment of swimming pool water is at its best.

The use of lye in cooking (caustic soda, ash water)

whitening caustic soda, keeping the natural color of ingredients such as: soaking dried fish, making olives less bitter, when canning citrus fruits, making botanical eggs, making ash cakes, rice cakes, or helping the noodles to be tough more, and closer to us is to use when cooking sugar to make moon cakes (helps to soften the crust, darker color).

Used in chemical industry, pharmacy

Where to buy lye Australia – In the chemical industry, pharmaceuticals, NaOH is used to produce products containing Sodium such as Sodium phenolate (Aspirin), Sodium hypochlorite (Javen), ….

Used in chemical cleaning industry

Sodium hydroxide and sodium compounds are important components in the production of laundry detergents such as Javen water. In addition, it is also used as a dishwashing liquid due to its ability to hydrolyze fats in animal fats and oils.

Some other applications of NaOH

Producing paper: used to process, whiten wood, bamboo, … with sulfate and soda technology.
Petroleum industry: used to balance the pH of drilling fluids, such as removal of sulfur, sulfur compounds or acid compounds in petroleum refining.
Textile and dyeing industry: used to make decomposition pectins, waxes in the processing of raw fabrics, making the fabric easy to absorb dye and gloss.

Is Sodium Hydroxide safe?

According to the Cosmetics Database, Sodium Hydroxide is a non-dangerous ingredient. But this compound is still considered to be “a potentially toxic or harmful substance”, many animal studies show that the brain, nervous system, digestive system of animals all react with Sodium Hydroxide. at low dosages.

When used in cosmetics, Sodium Hydroxide is considered to have quite aphrodisiac properties. Studies by the National Institute of Occupational Safety and Health of America (CDC) show that Sodium Hydroxide causes “eye, skin, mucosal irritations; skin burns, eye irritation; cause hair loss. ” CDC recommends avoiding direct contact with Sodium Hydroxide to the skin and eyes, which will cause a burning sensation and pain for approximately 3 minutes. However, if it is a diluted mixture, even after many hours of exposure, there will be no symptoms.

For the eyes, it may cause a burning sensation and discomfort, in extreme cases leading to blurred vision or blindness. ” With a 12% dilution, Sodium Hydroxide can destroy healthy skin cells within an hour. However, this depends mainly on the pH level, contact time, as well as the different skin types.

The Food and Drug Administration (FDA) recognizes Sodium Hydroxide as a safe compound when used as a food additive. In cosmetics, it is mainly used in cleansers, chemical peels, cosmetics and personal care products with different concentrations: a concentration of 5% is used to exfoliate at nails, toenails, with a concentration of 2% are used for normal hair straighteners, 4.5% for professional hair straighteners.

Independent review organization EWG rated the safety of Sodium Hydroxide as 3/10 (10 being the highest danger level).
