Detailed product introduction of betaine-type amphoteric surfactant CAB-35:

I. Basic information of CAB-35

1. Chemical name and alias

  • English name: Cocamidopropyl Betaine
  • Common alias: CAPB, betaine, cocamidopropyl betaine
  • Molecular formula: C19H38N2O3
  • CAS number: 61789-40-0

2. Structural features

CAB-35 is an amphoteric surfactant, which contains both anionic groups (carboxylate groups) and cationic groups (quaternary ammonium salts) in its molecules. Its amphoteric structure gives it unique mildness and surface activity.

II. Physical and chemical properties of CAB-35

  • Appearance: light yellow to colorless transparent liquid
  • Smell: slightly characteristic smell
  • pH value: 5.0-7.0 (1% aqueous solution)
  • Active matter content: 30%-35%
  • Solubility: easily soluble in water to form a clear solution
  • Biodegradability: easily biodegradable, environmentally friendly

III. Performance advantages of CAB-35

1. Excellent surface activity

  • It has a lower surface tension in aqueous solution, which significantly improves the wetting and decontamination ability of the solution.
  • It can synergize with other anionic and non-ionic surfactants to improve the overall cleaning performance.

2. Mildness

  • It has very low irritation to the skin and eyes, and is suitable for use in infant and sensitive skin care products.
  • When combined with SLES (sodium lauryl ether sulfate), it can significantly reduce the irritation of the system.

3. Good foaming performance

  • It exhibits stable foaming ability in hard water, and the foam is rich and delicate.
  • It can significantly improve the texture and durability of the foam.

4. Excellent antistatic property

  • It helps to reduce the accumulation of static electricity on hair or fabrics and enhance the combing and smoothing effect.

5. Biological compatibility and environmental friendliness

  • It is easy to degrade and will not cause secondary pollution to the environment.

Fourth, CAB-35 production process

1. Main raw materials

  • Coconut oil acid or its derivatives (such as coconut oil amide)
  • Propylene diamine (DMPA)
  • Ethylene oxide
  • Monochloroacetic acid

2. Process flow

  1. Coconut oil amidation: Coconut oil acid reacts with an amine reagent to form coconut oil amide.
  2. Quaternization: Coconut oil amide reacts with monochloroacetic acid to form a betaine structure.
  3. Post-treatment: A stable liquid product is obtained through purification, dilution and pH adjustment.

3. Process characteristics

  • The process is simple and suitable for industrial production.
  • Green chemical process to avoid the production of toxic by-products.

V. Main uses of CAB-35

1. Personal care products

  • Application scenarios: shampoo, shower gel, facial cleanser, hand soap.
  • Function: Gentle cleansing, conditioning skin, providing rich foam, enhancing product touch.

2. Household cleaner

  • Application scenarios: detergent, kitchen cleaner, floor cleaner.
  • Function: Improve detergency, enhance solution stability and foam performance.

3. Industrial applications

  • Petroleum industry: Used as a wetting agent and emulsifier to improve the chemical properties during oil production.
  • Textile industry: As a softener, enhance the feel and antistatic properties of fabrics.

4. Special uses

  • Used in antibacterial preparations to enhance the dispersion effect of antibacterial agents.
  • Used as a dispersant for pesticides and fertilizers to improve spraying uniformity.

VI. Market application cases of CAB-35

1. Well-known products

  • Shampoo: An international brand adds CAB-35 to significantly improve the fineness of foam and smoothness after washing.
  • Household detergent: Using the low irritation of CAB-35, a laundry detergent for children is developed.

2. Regional market

  • In Europe and North America, CAB-35 is widely used in green cleaning products due to its environmentally friendly properties.
  • In the Asia-Pacific region, due to the rapid growth of the personal care products market, the demand for CAB-35 has increased year by year.

VII. Safety and environmental performance of CAB-35

  • Toxicology data: No significant irritation to human skin and eyes, no allergenicity.
  • Environmental degradability: More than 90% biodegradability, in line with EU REACH and environmental regulations.
  • Sustainability: Derived from natural coconut oil, no pollution byproducts in the production process.

VIII. Packaging and storage of CAB-35

  • Packaging form: 200L plastic barrel or IBC barrel.
  • Storage conditions: Avoid direct sunlight and store in a cool and ventilated warehouse.
  • Shelf life: Under suitable conditions, it can be stored for more than one year.

IX. Development trend of CAB-35

  1. Technological innovation: Develop higher purity and lower irritation betaine products to meet the needs of the high-end market.
  2. Application expansion: Explore new uses in medicine, agriculture and other fields.
  3. Green upgrade: Promote the extraction of raw materials from renewable biological resources to reduce carbon footprint.
