Calcium lauroyl taurate (C11H23CONH(CH2)2SO3·0.5Ca, CaLT) was synthesized, and the internal structure and tribology were studied. The powder of CaLT is a plate type crystal whose structure is lamellar at room temperature. When the powder is applied to an artificial skin, the frictional coefficient is lower than that for other solid lubricants. Such a high lubricity is caused by disintegration of the powder aggregates, cleavage of the lamellar layers, and deformation of the powder particles.
