I. Product Overview
Betaine is a naturally occurring amphiphilic compound, and its most common industrial form is cocamidopropyl betaine (CAB). Betaine has been widely used in many fields due to its surface activity, mildness and environmental friendliness.
- Chemical name: Betaine or Cocamidopropyl Betaine
- Molecular formula: C19H38N2O3
- CAS number: 61789-40-0
- Main source: Naturally extracted from beets or derived from coconut oil.
II. Physical and chemical properties
- Appearance:
Usually a light yellow to colorless transparent liquid, some forms may be white powder or crystalline solid.
- Solubility:
- Easily soluble in water to form a clear liquid.
- Maintain chemical stability in a wide pH range (4-10).
- Biodegradability:
- Betaine is a highly efficient biodegradable surfactant.
- Environmentally friendly and will not cause secondary pollution.
- Chemical properties:
- It has good amphoteric surface activity, which can show cationic properties under acidic conditions and anionic properties under alkaline conditions.
- Very low irritation and toxicity.
III. Performance advantages
- Excellent surface activity
- It can effectively reduce the surface tension of water and enhance the wetting and dispersion ability of the solution.
- It shows good stability in hard water to avoid precipitation or failure.
- Rich and lasting foam
- It provides soft and delicate foam and is widely used in personal care products to enhance the use experience.
- Mildness
- It is almost non-irritating to the skin and eyes, suitable for infants and sensitive skin products.
- Antistatic and conditioning effects
- In hair care, it effectively reduces static electricity accumulation and improves the smoothness and glossiness of hair.
- Strong compatibility
- It can work synergistically with anionic, nonionic and cationic surfactants to enhance product performance.
Fourth, main application areas
- Personal care products
- Shampoo: Improves cleaning power, foam stability and product mildness.
- Shower gel: Gives rich foam, reduces dryness, and is suitable for a variety of skin types.
- Facial cleanser: Cleanses pores while moisturizing without irritating the skin.
- Household cleaner
- Dishwashing liquid: Enhances degreasing effect and improves the touch of hand skin.
- Multi-purpose cleaner: Suitable for floor cleaning, glass cleaning and other fields.
- Industrial application
- Petroleum industry: Used as an emulsifier and wetting agent to improve oil recovery efficiency.
- Textile industry: used in fabric softeners, reducing static electricity and improving textile quality.
- Agriculture
- Pesticide and fertilizer dispersant: Improve spraying uniformity and permeability of active ingredients.
V. Production process
The industrial production of betaine is usually produced by the reaction of coconut oil derivatives with sodium chloroacetate. The amphoteric structure originates from the synergistic effect of quaternary ammonium salts and carboxyl groups in the molecule. The main processes are as follows:
- Cocoamidation: obtained by the reaction of coconut oil acid and an amine reagent.
- Quaternization: react with chloroacetic acid to form the core structure of betaine.
- Post-treatment: purification and dilution, adjusting to a stable state.
VI. Safety and environmental performance
- Safety
- Skin tests show no significant irritation and can be safely used in cosmetics and care products.
- Low toxicity, in line with international cosmetic safety standards.
- Environmental performance
- High biodegradability, with a degradation rate of more than 90%.
- Comply with EU REACH regulations and environmental standards.
VII. Market trends and prospects
- Market demand
As consumers’ demand for mild and environmentally friendly products grows, the market size of betaine is expanding year by year.
- Regional development
- Asia Pacific: Strong demand for personal care products, betaine is widely used.
- European and American markets: Focusing on sustainable development, betaine is in high demand in the field of green cleaning.
- Technological innovation
- Launch high-purity betaine products to meet the needs of the high-end cosmetics market.
- Develop more efficient green production processes to reduce energy consumption and carbon emissions.
