Lauramidopropyl betaine

Lauramidopropyl betaine (CAS 4292-10-8) is an amphoteric surfactant derived from lauric acid, carrying both positive and negative charges depending on pH. It is commercially available under trade names including Mackam LMB, Lexaine LM, Amphosol LB, and Amphoteric L, and is registered under EC number 224-292-6.

In personal care formulations, lauramidopropyl betaine functions as a co-surfactant in shampoos and body washes, where it reduces the irritation potential of primary anionic surfactants while contributing to foam volume and stability. It also acts as an emulsifier in conditioning systems, helping to disperse oil-phase ingredients uniformly through aqueous matrices.

The material is subject to REACH registration requirements for EU market supply and should be handled in accordance with applicable SDS documentation. Procurement teams should confirm grade specifications, active matter content, and packaging formats directly with the supplier, as these vary by production batch and regional distribution agreement.
