- General Description
Caustic soda flakes is obtained from sodium hydroxide – technical grade, by electrolytic process.
It is a solid white, hygroscopic, odorless substance. Caustic soda flakes easily dissolves in water, with heat release. The product is soluble in methyl andethyl alcohols. Sodium hydroxide is a strong electrolyte (completely ionized both in crystalline and solution states). Sodium hydroxide is not volatile, but it rises easily in air as aerosols. It is insoluble in ethyl ether.

Standard Packaging and shipping Information
palletized polyethylene bags of 25 kg (permissible variation ±0.2kg) 1 ton (permissible variation ±5 kg) bags made of polypropylene lined with polyethylene.
Storage & Handling:
Keep the product in tightly closed and properly labeled containers. Do not store caustic soda flakes in aluminum container as flammable hydrogen gas can be produced.
Caustic soda flakes should be stored under dry and cold spaces well-ventilated in order to avoid dust forming and spreading. Never store caustic soda flakes together with other group of materials such as: acids and ammonium salts.
Health effects:
Please refer to the product Material Safety Data Sheet (MSDS) offering customers help to better satisfy their particular handling, safety and disposal needs and those that may be required by locally applicable health and safety regulations.
Additional Safety Information:
Caustic soda flakes is highly corrosive hazardous product. Avoid body contact. It is dangerous to eyes and skin. Destroys skin tissues and causes severe chemical burns. Inhalation of dust/mist can cause serious injury to respiratory tract. Ingestion can injure the digestive system.

- Exposure controls/personal protection
Control parameters Components with workplace control parameters
Exposure controls Handle in accordance with good industrial hygiene and safety
Appropriate practice. Wash hands before breaks and at the end of workday
engineering controls
Personal protective equipment Face shield and safety glasses Use equipment for eye protection
Eye/face protection tested and approved under appropriate government standards
such as NIOSH (US) or EN 166(EU).
Skin protection Handle with gloves. Gloves must be inspected prior to use. Use
proper glove removal technique (without touching glove’s outer
surface) to avoid skin contact with this product. Dispose of
contaminated gloves after use in accordance with applicable laws
and good laboratory practices. Wash and dry hands.
Body Protection
Respiratory protection
Control of environmental exposure
Complete suit protecting against chemicals, The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.
