Betaine Anhydrous CAS 107-43-7

Betaine (also known as Trimethylglycine) is a zwitterionic quaternary ammonium compound widely used in food, feed, pharmaceutical and cosmetic formulations for its osmoprotective, nutritional and humectant functions. It is supplied as a high-purity, free-flowing crystalline powder suitable for industrial and formulation use.

Physicochemical Properties

Applications

1. Animal Nutrition & Feed Additives
   • Used as a methyl donor to improve amino acid utilization and support growth performance in poultry, swine, aquatic animals and ruminants.
   • Helps regulate osmotic pressure and supports stress resistance during heat, transport or high salinity conditions.
2. Food & Beverage Industry
   • Functional ingredient in health foods, nutraceutical powders and beverages.
   • Supports homocysteine metabolism and is often combined with vitamins (e.g., B-complex) in dietary formulations.
3. Pharmaceutical & Healthcare
   • Used as an active substance or excipient in formulations related to homocystinuria and cardiovascular support, subject to local regulatory approvals.
   • Serves as a biochemical reagent in research on osmoprotection and cell metabolism.
4. Personal Care & Cosmetics
   • Functions as a mild humectant, skin-conditioning agent and anti-irritant in shampoos, facial cleansers, body wash and leave-on skincare.
   • Enhances moisture retention and improves skin feel without stickiness.
5. Other Industrial Uses
   • Osmoprotectant and stabilizer in fermentation processes and enzyme preparations.
   • Intermediate or additive in various specialty chemicals where a zwitterionic structure is beneficial.

Storage Conditions

• Store in original, tightly closed packaging in a cool, dry and well-ventilated warehouse.
• Recommended long-term storage temperature: below 25 °C, away from direct sunlight and heat sources.
• Protect from moisture – betaine is hygroscopic and may cake or liquefy if exposed to humid air.
• Keep away from strong oxidizing agents and materials that may generate dust ignition sources.
• Follow standard FIFO (First-In, First-Out) inventory practice and check packaging integrity regularly.

Safety Precautions

Handling

• Avoid formation and inhalation of dust; use local exhaust ventilation in powder handling areas.
• Avoid contact with eyes and prolonged contact with skin.
• Do not eat, drink or smoke while handling the product; wash hands thoroughly after use.

Personal Protective Equipment (PPE)

• Safety goggles or face shield to protect eyes from dust.
• Dust mask or suitable particulate respirator if airborne dust cannot be controlled.
• Protective gloves and work clothing.

Fire & Explosion

• The delivered product is generally not dust-explosion capable as supplied, but accumulated fine dust can form an explosive mixture with air; avoid ignition sources and reduce dust deposits.
• Use water spray, foam or dry chemical extinguishing media for surrounding fire.

First Aid Measures

• Inhalation: Move to fresh air; seek medical attention if discomfort persists.
• Skin contact: Brush off loose particles and wash with soap and water.
• Eye contact: Rinse immediately with plenty of water for at least 10 minutes; obtain medical attention if irritation persists.
• Ingestion: Rinse mouth; do not induce vomiting; seek medical advice if large amounts are swallowed.
