Personal Care

Application of SLS Needles (Sodium Lauryl Sulfate Needles)

1. Cleansing: Provides powerful detergency in shampoos, body washes, and household cleaners, effectively removing oils and soils.

2. Foam Generation: Creates rich, stable foam even in hard water and low concentrations, enhancing consumer perception of cleaning efficacy.

3. Emulsification: Facilitates the mixing of oil and water phases in creams, lotions, and industrial formulations.

4. Wetting Agent: Reduces surface tension, allowing formulations to spread evenly and penetrate surfaces effectively. 5. Solubilization: Helps incorporate water-insoluble ingredients into aqueous systems through micelle formation.
