Liquid Myristamidopropyl Betaine-CAS 59272-84-3
Liquid Myristamidopropyl Betaine (MAB-35) is a high-grade long-carbon-chain mild amphoteric surfactant refined from myristic acid raw materials through professional amination and betainization synthesis processes.
Compared with conventional CAB-35 (coconut mixed carbon chain) and LAB-35 (lauric single carbon chain), MAB-35 has a longer and more stable myristyl carbon chain structure, featuring richer foam, better lubricity and superior hair conditioning performance.
The product integrates the dual advantages of anionic and cationic surfactants, with stable chemical properties in full pH range and complex hard water environments. It has ultra-low skin and eye irritation, excellent foam fineness and persistence, and can significantly enhance the fluffy and dense feeling of compound cleansing formulas.
It possesses outstanding thickening and system stabilizing capabilities, effectively improving formula viscosity uniformity and preventing finished product delamination and precipitation.
In particular, MAB-35 has far better softening, anti-static and dry-frizz repairing effects than ordinary betaines, which can deeply smooth hair scales, improve dry and rough hair quality, and bring long-lasting smooth and fluffy hair texture. With excellent water solubility, full formula compatibility and complete biodegradability, it is a high-end upgraded variant of amphoteric surfactants, specially used for mid-to-high-end mild care and cleansing products.
