The Gold Standard of Mild Cleansing
High-performance taurine-based surfactant for premium care
Creamy Foam Texture
It creates a dense, stable, and fine-textured foam similar to whipped cream. Unlike other amino acid surfactants, its foam is highly resilient and doesn't collapse easily, providing a luxurious sensorial experience during use.
Hard Water Resistance
Excellent calcium and magnesium ion tolerance. It maintains its superior cleansing and foaming power even in hard water conditions, preventing the formation of "soap scum" and leaving skin feeling clean yet moisturized.
Biomimetic Mildness
Taurine is naturally present in the human body. This surfactant mimics the skin's natural chemistry, resulting in extremely low protein denaturation. It cleanses effectively without disrupting the delicate lipid barrier or causing "tightness."
🧪 Formulation Logic & Compatibility
1. Preparation & Solubility
For the powder form, heat the water phase to 50°C - 60°C and add SMLT under slow stirring. It dissolves faster than Lauroyl Glutamate, yielding a crystal-clear solution that remains stable even at lower temperatures.
2. Efficient Thickening
Unlike most amino acid surfactants, SMLT responds well to salt and amphoteric surfactants (like Cocamidopropyl Betaine). This allows formulators to achieve high viscosity in clear facial cleansers without excessive polymers.
3. pH Versatility
Optimal performance is found between pH 5.0 and 7.5. In this range, the surfactant provides the best balance of foam flash and skin mildness, making it ideal for tear-free baby formulas.
"Pair SMLT with Sodium Cocoyl Isethionate (SCI) for a 'syndet' bar or creamy paste. SMLT acts as a foam booster and solubilizer for SCI, resulting in a rich, soap-like lather that rinses off cleanly without residue."
