Hexadecyldimethyl Betaine (BS-16)
CAS 693-33-4
Hexadecyldimethyl Betaine (CAS 693-33-4) is a premium amphoteric surfactant that delivers exceptional mildness and performance across personal care and cleaning applications. This versatile ingredient is specifically engineered to enhance formulation quality through its unique triple-action functionality: it significantly boosts viscosity when combined with anionic surfactants, generates rich and stable foam with a luxurious sensory profile, and dramatically reduces irritation potential—making it ideal for sensitive skin formulas, baby care products, and premium shampoos. Manufactured under strict quality control to ensure low free amine content and light color, our BS-16 offers outstanding compatibility with all surfactant systems and excellent stability in hard water. Available in standard 30% active concentration with customizable options, it serves as a reliable foundation for creating mild, high-performing, and consumer-preferred rinse-off products.
>> Main Uses
Hexadecyldimethyl Betaine (BS-16, CAS 693-33-4) is extensively used as a high-performance mildness enhancer and multifunctional additive across personal care and cleaning industries. Its primary application lies in formulating gentle rinse-off products such as baby shampoos, sensitive-skin facial cleansers, and sulfate-free body washes, where it effectively reduces irritation while maintaining excellent cleansing efficacy. In hair care and skincare systems, it serves as a key viscosity builder and foam stabilizer that creates rich, creamy lather and improves product texture. Furthermore, its exceptional compatibility enables versatile use in household and institutional cleaning products—including hand soaps, dishwashing liquids, and all-purpose cleaners—where it contributes to mildness, foam volume, and formulation stability. This surfactant also finds specialized applications as an emulsifier, antistatic agent, and compatibility booster in industrial formulations, textile processing, and hard surface cleaners.
