Lauryl Betaine(Dodecyldimethyl Betaine)-CAS 683-10-3
Lauryl Betaine, chemically named Dodecyldimethyl Betaine or Dodecyldimethylammonioacetate, is a high-efficiency mild amphoteric surfactant.
Its INCI name is Lauryl Betaine, with exclusive CAS No. 683-10-3 and EINECS No. 211-669-5.
The molecular formula is C₁₆H₃₃NO₂ and the average molecular weight is 271.44 g/mol.
Synthesized from lauryl dimethylamine and chloroacetic acid through advanced amination reaction, our cosmetic-grade Lauryl Betaine adopts low-impurity refining technology, with standard active ingredient content of 30%±1% and customizable high-purity specifications.
The product appears as colorless to pale yellow transparent viscous liquid.
It features stable amphoteric activity, outstanding hard water resistance, acid and alkali resistance, low irritation and excellent foaming performance.
The 10% aqueous solution pH value is stably maintained at 4.0–6.0, with strong compounding synergistic effect.
It can effectively reduce the irritation of anionic surfactants, thicken formulas and improve foam stability.
The minimum order quantity is 1KG.
It is widely applied in mild personal cleansing, hair care products, daily detergents and cosmetic formula conditioning systems.

Lauryl Betaine(Dodecyldimethyl Betaine)-CAS 683-10-3
Lauryl Betaine is a classic lauryl-based amphoteric surfactant widely used in global daily chemical and cosmetic industries. It integrates the advantages of anionic and cationic surfactants, featuring balanced foaming, cleansing, thickening and antistatic properties. With ultra-mild skin and scalp affinity, it avoids dry and tight discomfort after cleaning, and can significantly optimize the mildness and stability of compound formulas. It maintains stable performance in complex hard water and wide pH environment, with excellent dispersion and formula conditioning effects. Different from traditional surfactants, it has low impurity content, high safety and excellent environmental degradability, serving as a core green functional raw material for high-end mild cleansing and daily care products.
Key Benefits
• Ultra-Mild & Low-Sensitization: Pure lauryl-based formula, non-irritating to skin and scalp, effectively reduces overall formula irritation for sensitive skin care.
• Excellent Foaming & Stabilizing Performance: Produces dense and fine persistent foam, stable foaming capacity even in high-hardness water environment.
• Powerful Compounding Synergy: Perfectly compatible with anionic, cationic and non-ionic surfactants, significantly improves formula thickening and stability.
• Outstanding Antistatic & Conditioning Effect: Eliminates hair static electricity, smooths frizzy hair, and softens skin after cleaning.
• Strong Environmental Adaptability: Stable efficacy in wide pH range and hard water, no stratification or performance degradation during long-term storage.
• Eco-Friendly & High Safety: Fully biodegradable, low heavy metal residues, compliant with global green cosmetic safety standards.
Applications
• Mild Facial Cleansing Products: Widely used in amino acid facial cleansers and mild cleansing formulas to achieve gentle and non-drying deep cleaning.
• Professional Hair Care Products: Applied in various shampoos and hair conditioners for foam stabilization, antistatic and hair smoothing conditioning.
• Body Daily Cleansing: Ideal for body wash, hand soap and daily cleaning products to enhance foam fineness and product mildness.
• Low-Irritation Sensitive Care: Suitable for sensitive skin daily care and mild household detergent formulas with high safety requirements.
• Cosmetic Formula Conditioning: Serves as thickener, stabilizer and dispersant in cosmetic formulas to optimize product texture and usability.
