Unique Amphiphilic Properties
Sarcosinlau PW features a hydrophobic 12-carbon lauroyl chain and a hydrophilic carboxylate group, granting it amphiphilic characteristics. The nitrogen atom within its amide linkage remains neutrally charged across all pH levels, while the carboxylate group, with a pKa of approximately 3.6, becomes negatively charged in pH environments above 5.5. These properties contribute to its stability and performance in various formulations, particularly in pH ranges from 5.5 to alkaline conditions.
