Product Usage

Lauryl Hydroxysultaine is widely used in personal care and household cleaning products. In shampoos and body washes, it significantly enhances foam richness and creaminess while reducing the irritation caused by traditional anionic surfactants (e.g., SLES), imparting mild conditioning effects to skin and hair. In facial cleansers and baby care products, its low-irritation characteristics are particularly valued. Additionally, it serves as a thickener and foam stabilizer, improving product rheology and sensory feel. In dishwashing liquids and laundry detergents, it enhances detergency while reducing skin irritation to hands. In industrial applications, it can be used as a solubilizer and emulsifier in oilfield chemicals and textile auxiliaries.
