Liquid Stearamidopropyl Betaine-CAS 6179-44-8
Liquid Stearamidopropyl Betaine (SAB-35) is a top-tier C18 super-long carbon chain mild amphoteric surfactant refined from high-purity stearic acid through advanced amidation and betainization synthesis technology.
Compared with medium and long carbon chain betaines, SAB-35 achieves unprecedented ultra-high lubricity and long-lasting smoothing effect, with unique residual film-forming performance that delivers durable silky hair texture after rinsing.
The product integrates the dual advantages of anionic and cationic surfactants, maintaining stable physical and chemical properties in full pH range and complex hard water environments. It has ultra-low skin and eye irritation, soft and delicate foam, and can significantly upgrade the moisturizing and silky touch of compound cleansing formulas.
In addition to conventional thickening and stabilizing functions, SAB-35 excels in deep repair of chemically damaged hair, long-term anti-static and anti-frizz effects, effectively solving common pain points such as dryness, roughness, tangling and short-term smoothness attenuation of high-end hair care products. With full formula compatibility and complete biodegradability, it is the core exclusive raw material for luxury long-effect smoothing and repair-type personal care products.
