Product Description
Lauryl Hydroxysultaine is an amphoteric surfactant featuring a long-chain lauryl group and a hydroxysultaine functional group. This molecular structure gives it surface-active properties that make it useful in cleansing and foam-forming formulations.
In personal care products, Lauryl Hydroxysultaine is commonly used as a supporting surfactant to improve lather characteristics and help formulators manage viscosity and overall product feel. Its performance depends on the primary surfactants, formulation pH, concentration, and other ingredients in the system.
Beyond personal care, it may be evaluated in selected household and industrial cleaning formulations where its surfactant properties are beneficial. The appropriate grade should be selected according to active matter, physical specifications, compatibility requirements, and the intended application.
For commercial use, confirm the supplied material's identity and specifications with the current Technical Data Sheet (TDS), Safety Data Sheet (SDS), and batch-specific Certificate of Analysis (COA).

Product Applications
1. Shampoo Formulations
Lauryl Hydroxysultaine can be used in shampoo systems to support foam formation and cleansing performance. Its dosage and compatibility should be optimized alongside the primary surfactants.
2. Body Wash and Shower Gel
In body cleansers, it helps develop a rich lather and can contribute to the desired texture and rinsing experience of the finished product.
3. Facial Cleansers and Hand Wash
It may be incorporated into facial cleansing products and liquid hand soaps as part of an amphoteric surfactant blend. Finished-product mildness and skin compatibility should be evaluated for the intended use.
4. Household Cleaning Products
Lauryl Hydroxysultaine can be assessed in selected household cleaning formulations where foam characteristics and surfactant compatibility are important to product performance.
5. Industrial and Specialty Formulations
Depending on the grade and technical requirements, it may be evaluated for selected industrial cleaning, oilfield, or textile-related formulations. Confirm suitability through application-specific testing before commercial adoption.
